Firefox 39.0 zoom does not in the preview Windows 10 Pro

When I Zoom in on a web page to get to a readable size comfortably, the zoom is as long as Firefox is running. But if I closed Firefox and then restart it, the zoom has been reset to the default state. He holds the zoom to the point settings Windows 8.1. Don't know if it's a Windows 10 vulnerability or a situation that Firefox will need to take care when the final version of Windows new starts installing the 29.

Thank you FredMcD and cor-el for your answers. But the problem seems to have resolved itself. The available settings are now, but I did nothing to cause trouble that I know. Microsoft is pushing updates at the premiere of Win10, then maybe one of those who did it. All the settings of Firefox 39.0 were and are exactly the same as on a couple of my 8.1 boxes which are always held for expansion without problem.

    I get a pop up box with the message: Application JavaScript error: "setTimeout" called on an object that does not implement the interface Window for Firefox.

    But it seems to appear when I go to Amazon.com. Then he opens with this message and the OK option? But as fast as I can click OK, another box appears. After all a half dozen, she disappears - until what I move to another part of Amazon! I uninstalled - reinstalled and then - Firefox and BA. I do not understand this!

    (And of course, there is always the possibility that it is not only attacking me on Amazon... There may be a lot of other sites that also trigger, and I just haven't been there yet.)

    Hello

    Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • In Firefox 29,0 and above, click on the menu button

      click Help

      then select restart with disabled modules.

    • In previous versions of Firefox, click on the Firefox button in the upper left of the Firefox window and click help (or click on help in the Menu bar, if you do not have a Firefox button) and click on restart with disabled modules.

    If Firefox is not running, you can start Firefox in Mode safe mode as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac: Hold the option key during the startup of Firefox.
    • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
      (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. This might help others with the same problem.

  • SideWinder X 4 does not disable the left windows key in games

    SideWinder X 4 does not disable the left windows key in games.

    When on the windows desktop, he will have the disabled windows key and a small box will popup in the lower right corner, saying he is.
    But if I press it, then in a game (fullscreen), it will be the game tab down, put me to what is "beneath" and open the start menu.
    I tried both Intellitype 8.2 and the latest Microsoft Mouse and keyboard Center but they both react in the same way.
    The Bank or the profile is set to number 2 (game) and of course, the windows key is disabled in the settings. Even if I turn it off on THE 3 banks it'll always exhibit the same behavior.
    I tried to implement the individual profiles for the games that I play as well but no luck there either. And re - install the drivers does not help.
    It completely defeats the purpose of this feature. Ideally, she would work on the other hand, being active only in an office environment and disabled in games/full screen applications, but it should at least work as announced, following the rules laid down by the Bank or the current profile.
    In addition, the auto feature does not work with these games or the other and some applications as well. Am I alone in having these problems? I'm ready to completely reinstall windows because it's *.
    Any help/ideas please?

  • Virtual machine does not start the Server Windows 2003 Std ISO file?

    Hello

    I am trying to create a virtual Windows 2003 machine, I created the ISO file, downloaded on my ISO library and connected the CDROM drive for the ISO file.

    When I boot the maching, I select the start menu and select the CDROM drive the virtual machine starts the ISO?

    The continuous boot just on the network card boot.

    It's as if the virtual machine does not see the CDROM drive?

    I use folder2iso

    To me, it sounds as if the ISO created may not be bootable! How did you create the ISO file?

  • Firefox on Ubuntu Linux does not open the PFD files (blank tab opens)

    Firefox running on Linux (Ubuntu 13.04).
    When I click on any file (or attachment) which is in PDF format, Firefox opens a blank tab and display content.
    I saw a similar question for Apple computers, but it does not work under Linux and neither does Windows patches. It only started with the last udate to Firefox.
    Unfortunately, like most people, I did the stupid thing and update, then went nuts loading of modules so it could be an add-on and not only the update.
    The same problem occurs on thre PC (AMD and Intel) - one on the Mint and the rest on Ubuntu

    That's all,

  • Since the update to Firefox 22 Twitch.tv does not load the player more

    I've just updated to Firefox 22 and no Twitch.tvplayer simply does not load. Just a black rectangle where the player is supposed to be and if I right click in this area, I get the same menu as everywhere else, which means that the player certainly didn't load. YouTube works fine however.

    If you use extensions (Tools > Modules > Extensions) as NoScript , Adblock Plus or Ghostery which can block content, and then make sure that these extensions are not blocking the content or Block of Flash .

  • 12 Firefox on OS Lion does not obtain the crash report on a second account on the past. On the main account (admin) it works very well and also on a third test account.

    12 Firefox does not get beyond the crash report. This is a second account (standard). However, it works very well on a third party, as well as on the main one admin account. I reinstalled Firefox, disc repaired permissions and so on, but nothing helped. For the second account .plist file could be damaged? I can't remove it because of permissions so cannot test this. Please notify.

  • On all websites, buttons at the top don't work, such as the sign in and sign buttons. Also the scroll up button doesn't work. I click on the scroll bar to move upward. I just upgraded to Firefox 901 and it does not solve the issue.

    If a button is in the top 24 mm of a web page, it does not. This includes the scroll bar. If one button operation below that is introduced in this area, it stops working. The dead zone is across the entire screen. I've upgraded to Firefox 9.0.1 and it did not fix the problem. Think that question may have started after I installed a program called Babylon and it installs a browser bar. Deleted the program and the bar of the browser, but did not affect the dead zone.

  • I have Firefox 22.0 who does not read the .js files. How could I fix it?

    I think that the problem started after I installed also Chrome on my computer. But I do not know...

    If this happens again, you can try basic steps as for the problems with web pages:

    Reload Web pages and ignore the cache to refresh potentially stale or corrupt.

    • Hold down the SHIFT key and click the Reload button
    • Press 'Ctrl + F5' or 'Ctrl + Shift + R' (Windows, Linux)
    • Press 'Command + shift + R' (Mac)

    Clear the cache and cookies from Web sites that cause problems.

    "Clear the Cache":

    • Firefox/tools > Options > advanced > network > content caching Web: 'clear now '.

    'Delete Cookies' sites causing problems:

    • Firefox/tools > Options > privacy > Cookies: "show the Cookies".

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/Firefox/tools > Modules > appearance).

    Hi AymanTakieddin:

    Many of SP2 for Vista and Win 7 SP1 users currently have the same problem.  If you leave Windows Update running for several hours and do not see an error message if you think that "check for updates..." will be finally executed completion and the report that the updates are available for download.

    If this does not help, see the step-by-step instructions posted on 16 June 2016 wire m #l's updates does not, he has been looking for updates for hours.

    These instructions are based on the instructions on the page Web of Dalai Search for Windows Updates takes forever?-a possible solution http://wu.krelay.de/en/ and take you through the process of finding a Windows kernel-mode driver (Win32K.sys) updates currently absent from your system, download the standalone update packages (.msu file) from the Microsoft Download Center and pre installation of these missing updates (in order from oldest to the most recent) before running Windows Update in order to install your remaining updates.  This work around usually decreases "checking for updates..." a few hours to ~ 20 min.

    If you have completely connected from may 2016 there should be only a lack Win32K.sys update - KB3161664 - you must install before running Windows Update to install remaining this month dozen or so June 2016 Patch updates Tuesday.

    Create a new profile as a test to see if your profile is the source of the problem.

  • Equium A110-280 does not read the disk Office XP PRO!

    Hi all

    Is there anyone who knows how to install MS Office XP PRO on my satellite A110-280?

    I have a full version of Office XP pro, but this strange pc does not even read the cd...
    Cd station just continue, and nothing happens.

    I tested the cd on the other two machines, and there is no problem.
    Also tested another cd on the A110 and they get up in Explorer, but the office-cd does not work...

    Is this something strange happens simply on Toshiba?

    Best regards Patrick

    Hello

    It s nothing unusual, I know a lot of cases where the CD/DVD drive could not handle a drive

    In this case you could copy/burn the Office CD with the help of another computer!
    After this attempt to install the desktop software using this second disc!

    I think that might help you.
