• Computer off, showing U2913WM "there is no signal from your computer press any key on the keyboard.

  Hi all

  Any help on this incredibly annoying would be much appreciated; I googled the out of him, but without success. I have a month or so old Dell U2913WM which I am more than happy with picturewise, but he demonstrated a very annoying problem. Whenever my PC goes to sleep, or worse, when I turn off my system, the monitor goes power save mode BUT after 30 minutes or so flashes upward:
  "There is no signal from your computer. Press any key on the keyboard or move the mouse to wake him up. If there is no display, place the monitor button now to select the correct input in the on-screen Display menu source. »
  It then repeats this message every 3 minutes approximately.

  I tried to reset the options in the menu of the screen, change the PC drivers (although this may not be the issue once the PC is turned off) and checking the dual link cable DVI for bent pins. Nothing worked and he drives me crazy! I have also another 22 "Dell Ultrasharp plugged on the GTX 780 and who falls asleep without problem. Any help would be most welcome!

  Thanks :)

  OK I fixed this annoying problem. I thought I'd post here in case someone else falls on this problem.

  To remedy this I simply connected via DisplyPort and the monitor is no longer wakes himself of no apparent reason.

• If Firefox is set as the default browser and any application tries to open a new window, it doesn't work and I get the error "Firefox is already in running... »

  Here's what I'm running:
  Microsoft Windows 7 Service Pack 1, fully updated to 04/10/2012
  New installation of Firefox 11. No add-on enabled following troubleshooting.
  I am a user has administrator rights
  SAMU is disabled.

  For starters, this has happened since Firefox 10 or more. A couple of months now.

  I am able to open Firefox. My modules worked (ABP, Flashblock, ABP Element Hiding Helper, IETAB2, Downthemall, Greasemonkey, extension of 4chan) had no problem. Firefox is defined and has been fixed for the past two years as my default browser.

  But since about 10 or so, maybe Firefox before, if I opened a session of Firefox and any other application attempts to open a session in a new window, I get the Firefox is already running but not responding do not error. »

  I tried to follow the advice of already posted troubleshooting (glance to parent.lock files left [no date], several sessionstore.js [no date] files, create a new user profile, has tried to erase the 'read only' permission in windows 7, but as soon as it is cleared, only read permission back.)

  As a last resort, I deleted the Firefox folder, the directory %APPDATA%/Mozilla in its entirety and then used CCleaner to remove all references to Firefox in the windows registry, and then made a complete re - install, without extensions installed right now.

  I checked the preferences and have the option "open new windows in a new tab" checked. The problem persists without worrying if this option is checked or not. This problem persists in or out of safe mode, even with the new facility.

  Test case:

  All cases:
  Firefox is selected as the default browser for windows 7

  Case 1: Log in to firefox. Use any other program that is trying to open a link to their Web site in a new window browser or the new browser session. "Firefox is already running" error

  Case 2: Open a firefox session. Right click on Firefox in the taskbar. Select 'open in new window '. "Firefox is already running" error

  Case 3: Open a session of firefox. Select the Firefox Menu > new tab > new window. In fact, a new window opens.

  This is the only method of opening a new window in the same browser session or profile that actually works on my system. Attempting to open a browser session from the task bar "open new window dialog" or opening a new window while a current window/session is running will not open firefox in a new window or a new tab in the current session. The "Firefox is already running, but is not responding" error will occur every time.
  

  Make sure that you do not start Firefox with the - No.-remote switch or have defined the MOZ_NO_REMOTE = 1 environment variable (Control Panel > system > advanced > environment variables).

• Set the default browser for Flash CS6

  How can I configure the default browser used by Flash when I hit the F12 key.

  Currently it is by default I.e. who doesn't there seem to be problems with the flash player even if it says it is installed. However Chrome works well, but for reasons that are other words that anybody's guess doesn't seem to like it.

  In any case, I think that the simple solution would be to simply change the default browser Flash wishing to use. UN fortunately an hour and a half of research has made no apparent solution to this task.

  Can anyone tell me where and how can I accomplish this?

  I expect it to be the same on Windows as on Mac, and it will use the default browser of your system. Try to change Windows so that the default browser is Chrome.

• How to set the default browser after update 35.0

  I've just updated to version 35.0 today. Now, every time I restart my browser that asks me to make Firefox the default browser. I've always said yes and check the box to remember. It does not work. Research help and did what was told to go into Control Panel, then programs and by setting the default value for it. That no longer works. I've never had this problem before. I'm at a loss to know what to do. Any suggestions would be greatly appreciated. Thank you.

  You can check for problems with preferences.

  Delete possible user.js and files numbered prefs-# .js and rename (or delete) the file prefs.js to reset all the prefs by default, including the prefs set via user.js and pref which is no longer supported in the current version of Firefox.

• new tab to go to the default browser, why not?

  I went to about: config, browser.newtab and set the default browser to google, and as long as I continue to work in the new tab opens this session at google. But if I connect to internet, close the browser and reopen the first tab goes to google, but any new tab goes to start.iminent.com/startweb/1033/Newtab.aspx. Very frustrating! Help, please.

  But, the closer you have an extension named Iminent, so this file can be re-created immediately if you delete that. Serves no useful purpose known?

  You can review and off and usually remove unwanted extensions on page modules. Either:

  • CTRL + SHIFT + a
  • Firefox orange (or the Tools menu) button > Add ons

  In the left column, click Extensions. Then, when in doubt, turn off.

  Typically, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

  Note: If the button Delete is missing, you must generally remove the extension via the Control Panel, uninstall a program. I suggest you click on the column "installed on" section so the more recent articles are grouped.

  A little luck?

• How can you make Firefox the default browser when the normal route does not work?

  Im trying entirely chrome once a friend showed how my firefox got his act together. However I can't for the life of me set it as default browser. I tried the 'make firefox the default browser' button in firefox, making that opens the windows default programs Panel. Whenever I try to use the Panel she simply sets the Protocol http for every night, which is not yet installed! ( http://puu.sh/2vJHM ) I think that a possible solution would be to change the registry manually, but I don't know where to start.

  Thank you for your help, but I managed to fix it by myself. The registry key for the associations of html and URLs of firefox have been corrupted so I scoured their in regedit (at HKEY_CLASSES_ROOT\FirefoxHTML and HKEY_CLASSES_ROOT\FirefoxURL) and them deleted entirely, then redid them by clicking on the make default firefox button in the options.

• xdg-open does not take into account the url and opens the different website when Firefox is the default browser in Ubuntu

  I am running Ubuntu 14.04 64 bit with Firefox version 38 for Ubuntu
  It is complected, and I tried to explain everything clearly.

  Today, I noticed a strange behavior.
  I have several URL saved as .desktop files.

  I use webupd8.org as example.
  The code for the exec in the desktop file is:
  Code:

  Exec=xdg-open http://www.webupd8.org/
  

  Today, I noticed that if I try to go to webupd8.org, or most of the other sites, by launching the .desktop file for this site, or by typing the url
  Code:

  http://www.WebUpd8.org/

  in the dashboard Firefox opens to a completely different site. The site that opens is a site that I set up for my children's grandparents to watch videos and see photos of the children. This Web site opens each time. I'm not be directed to a site at random each time. This is the case when I try to visit the webupd8.org OR one of several websites using .desktop file or enter the url you want in the dashboard. Whenever I went to my own domain.

  It happens that I have also several sites registered in a reminder in the Firefox icon in the Launcher sidebar thing in Ubuntu.
  In the case of the beast, the exec code is slightly different and it still responds as it should. In this case, I have:
  Code:

  Exec = firefox-new-tab http://www.webupd8.org/

  Also, if I change my default in opera browser, for example as .desktop files and entering the url directly in the dashboard work as it should.

  To recap:

  When Firefox is the default browser, enter a url in the dashboard or use a to surf to a desired site .desktop file causes my be redirected to my own domain name (which is hosted remotely and not on this computer).

  If, however, I change the Exec command in the .desktop file
  Code:

  Exec=xdg-open <url>
  

  TO
  Code:

  Exec = firefox-new-tab < url >

  the .desktop file will open Firefox and go to the desired site.

  If I change the browser by default Firefox to another browser, everything works as it should and has always so far. That is, with the Opera for example, both
  Code:

  Exec=xdg-open <url>
  

  and
  Code:

  Exec = firefox-new-tab < url >

  result in the browser by opening and going on the planned site. Typed a url in the dashboard is not a problem if the default browser is not Firefox.

  Anyone seen this before? If so, how to solve it?

  Thank you very much for your answers!
  I checked the url of the home page in Firefox and it has been set at startpage.com, but then when I looked at the default programs in Ubuntu, I noticed that the default program for the web had been unintentionally configured to use a .desktop file that leads to t he admin for my Web site login page.

  I changed this back to Firefox and the problem was solved.

• Addition of Google Chrome, now Safari does not open, impossible to link electronic mail links.  Just received message "Safari is closed."  Tried deleting 3rd party add ons. Is went into preferences, Safari is the default browser, but it does not open.

  Add Google Chrome, now Safari opens Cannot link e-mail links.  Just received message "Safari is closed."  Tried deleting 3rd party add ons. Is went into preferences, Safari is the default browser, but it does not open.

  Third party extension and plug-ins?

  If Safari is slow, unresponsive, which closes unexpectedly, or has other issues

  The problem may be caused by a Safari Extension, Internet plug-in or another add-on.

  The safari Extensions, Internet plug-ins, and other modules are designed to improve or customize the browsing experience. Modules are widely available on the Internet, and some are installed as part of an application or other software. If you have Add-ons installed, an add-on might be at the root of the issue.

  If the problem is the unwanted pop-up windows, advertisements and graphics while surfing on the web, discover how to remove the ad-injection (adware) from your Mac software.

  Disable the Safari Extensions

  You can disable Extensions Safari to learn if all are causing the problem.

  1. In the Safari menu, choose Preferences.
  2. Click the Extensions icon, and then select an extension from the list.
  3. Uncheck the box enable disable this extension.

  If turning off an extension solves the problem, look for updates of the extension by clicking Update in the lower left corner of the window. Or remove the extension by clicking on the button uninstall.

  Remove Internet plug-ins and other add-ons.

  You can remove Internet plug-ins and other add-ons to see if everything is the origin of the problem. To find them, quit Safari and open these folders in library:

  • The library folder at the top level of your hard drive. Open it from the Finder by choosing go > go to folder in the menu bar. Then type /Library and then click OK.
  • The record library in your home folder. Open it by organizing the Option while choosing go > library in the menu bar.

  The folders in the library contains the following folders for modules. Move all the files in these folders to the trash.

  • Internet Plug-Ins
    Do not remove the default Browser.plugin, nslQTScriptablePlugin.xpt, Composer.webplugin of Quartz or QuickTime Plugin.plugin.
  • Input methods
  • InputManagers
  • ScriptingAdditions

  If the removal of the files in these folders solves the problem, quit Safari again and gradually put the files until you find the one at the origin of the problem:

  1. Open the Recycle Bin and select one of the files that you removed. Chose file > back up. The file back to its folder.
  2. Open Safari and see if the problem returns.
     • If the issue is returned, you have identified the add-on causing the problem. Do not use or contact its manufacturer for an updated version.
     • If the question does not return, quit Safari and put back another file.

• I can't change the default browser on iMac.

  I am running Yosemite on my iMac.  I want to change it the default browser to Chrome, Safari, but in preferences, no navigation software is displayed.

  I don't know how Chrome has set as the default, but it's a pain to wait for it to load when I click on a url (by mail, for example).

  Although the problem is not the same, please follow the instructions in this article to support to reset the launch Services database.

  Instead type the command as shown in the article, I suggest that you copy and paste the web page in the Terminal window. Make sure you only select the whole line before copying. One way to do that is to triple - click anywhere in the line.

  If you do not already have a current backup, back up all data before proceeding. You should perhaps log out or restart to see a change.

• Firefox won't be the default browser for a user and pins himself to the taskbar

  On my Windows 7 PC parents, Firefox always said my mother is not the default browser (giving him the possibility to make sure) and then when closing, he pinned himself to the task bar.

  I checked and Firefox to default programs "has its flaws. I tried to get IE by default and then back to Firefox but the problem persists. The PC has no other browsers on it. Clicklinks in Thunderbird cause Firefox open, there'S no so it seems as if it is actually the default.

  When Firefox is closed it still pin himself to the taskbar. I can detach it and when it closes, it is still there.

  Search on Google, I have a suspicion that pinning occurs when the default configuration of Firefox. I also have a suspicion that something is wrong with the default for HTTP as it does not exist as a protocol to control custom Programs\Set Associations

  I have it solved!

  The command "Firefox.exe - silent - setDefaultBrowser" seems to have restored the HTTP protocol in control custom Programs\Set Associations.

  I found this command on http://kb.mozillazine.org/Setting_Your_Default_Browser#Force_Firefox_to_make_itself_the_default

  Thank you!
