• Since W10 is released, Firefox seems to have been sabotaged.

  Since W10 is released, Firefox seems to have been sabotaged "voluntarily."

  Repeatedly, I asks me to change my default on firefox browser, despite the fact that it is long established as such.
  It runs much more slowly, with a lot more mistakes.
  I now get apparently screen continuous updating, making almost impossible email screen freezes when it "thinks".
  I now get messages of error of pursuit "(firefox ne répond ne pas) '."

  Hope you can do some alternatives.

  Firefox 40, scheduled to be released next week, will have many patches of compatibility for Windows 10. I hope that will address several issues that you are facing.

  Since you seem to be an "early adopter" type person, you want to try Firefox 40 in his last days of tests?

  Note: Some extensions is perhaps not compatible with Firefox 40, especially the toolbars now of security which tend to be updated simultaneously with or shortly after Firefox versions.

  The following procedure will not remove your settings; don't uninstall NOT Firefox, that does not need.

  (A) download a complete Installer for Firefox 40 'beta' of https://www.mozilla.org/firefox/beta/all/ in a convenient location. (Scroll down your preferred language).

  Note: to retain the use of your plugins installed, I suggest the 32-bit version.

  (B) the release of Firefox (if any).

  (C) to rename the program folder, either:

  (Windows 64-bit folder names)

  C:\Program Files (x86)\Mozilla Firefox
  

  TO

  C:\Program Files (x86)\OldFirefox
  

  (Windows 32-bit folder names)

  C:\Program Files\Mozilla Firefox
  

  TO

  C:\Program Files\OldFirefox
  

  (D) to run the installation program that you downloaded in the #1. It should automatically connect to your existing settings.

  No improvement after this installation?

  Note: Some plugins can only exist in this OldFirefox file. If it is missing something essential, present in these files:

  • \OldFirefox\Plugins
  • \OldFirefox\browser\plugins

  When the final version of Firefox 40 becomes available (approximately 11 August), I propose to install this beta because will be auto-updated to Firefox 41 shortly after and unless you like software testing, maybe it's a little more adventure you are looking for.

• Firefox seems to have recently developed seemingly random usually do not remember bookmarks, particularly when the pc does not stop correctly. Thank you

  Firefox seems to have recently developed seemingly random usually do not remember bookmarks, particularly when the pc does not stop correctly. Thank you

  If Firefox detects that the places.sqlite database is corrupted then Firefox can create a new database file and import bookmarks from a JSON backup that does not contain the most recent bookmarks (a new JSON backup is created when you run Firefox for the first time on a day), then you may lose the bookmarks in such a case.

  You can check for problems with the database places.sqlite file in the Firefox profile folder.

• Firefox seems to hang or take a break for about 10 seconds after selecting a file in a file upload field

  Windows 7.

  This happens on all websites that uses a file entry box to download images/files.

  I click on Browse.

  Select a file, and then click "Open" in the file browser window.

  Then, firefox seems to hang or take a break for what it is between 5 to 12 seconds, after this time, the name of the file appears in the file input field - you cannot interact with the browser at all during this time.

  Can be reproduced every time i run firefox - does not happen in IE or another browser on that machine.

  Can you check this problem on Firefox 9?

• Text in firefox seems bad

  On some sites the text (font) seems wrong and nearly broke.
  Reload the Web site using Ctrl + F5 will correct the text, but recharge using F5 only make the wrong text appear again.

  Searching I found a suggestion that cost disabling hardware acceleration might help, but I already tried this suggestion with no luck.

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

• Firefox seems to be ignoring DNS TTL and DNS resolved cache indefinitely

  Hello

  Since we started to serve our js and css by CloudFront a few weeks ago, we started to see a problem with Firefox, where these goods would not sometimes be charged.

  So far, the only way I could reproduce the problem has been to load our home page in the afternoon, without closing my browser and then refresh the page the next day morning. I know it's pretty extreme, but some customers reported this problem, which means that it happens in both real life scenarios. We have been able to reproduce it on Windows and OSX from our office in New York and Krakow, Poland.

  I used Firebug to track down this problem and it seems that Firefox is ignoring the TTL of DNS queries when looking for URLS and caches them almost indefinitely. Due to the constant rotation of the CloudFront servers, after enough time the cached IP address server unresponsive and all applications are abandoned (applications abandoned on the screenshots). That sounds like a plausible explanation? Has anyone have the same problem and has a solution for this?

  Screenshot taken: 2013 - 06-13 at 22:29:30 watch the page loaded with success, then one taken on 2013-06-14 at 09:33:30 watch tab firebug "Net" with all requests of the asset given up. Force-refresh the page several times allows, as shown in the screenshot of 09:34:03.

• Update of Firefox seems to be frozen. The mouse does not work on Firefox at all.

  I updated Firefox when it was asked to do. Now, when loading, the mouse doesn't on Firefox at all. I've seen suggestions to go in the Options or help, but frankly, it's impossible because the screen seems to be totally frozen. The only thing I can do is to open the Task Manager and close the program.

  I will note that once or twice, it seems to work very slowly. For example, I would like to click on something and about a minute or later, he would answer a little bit, but again, the mouse never seemed not at all working again.

  Do a clean reinstall and remove the Firefox program folder before reinstalling a new copy of Firefox.

  Download a new copy of Firefox and save the file to the desktop.

  • Firefox 20.0.x: http://www.mozilla.org/en-US/firefox/all.html

  Uninstall your current version of Firefox, if possible, the settings in the software security and cleaning of the Windows registry.

  • Do NOT remove the data personal when you uninstall your current version of Firefox, because all profile files will be deleted and you will also lose your personal data such as bookmarks and passwords from other versions of Firefox profiles.

  Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

  • It is important to remove the Firefox program folder to delete all the files and make sure that there is no problem with the files that were the remains after uninstallation.
  • http://KB.mozillazine.org/Uninstalling_Firefox

  Your bookmarks and other profile data is stored in the Firefox profile folder and will not be affected by a uninstall and (re) install, but make sure that 'delete personal data' is NOT selected when you uninstall Firefox.

• Accidentally allowed AVG PC Tuneup set up something and I don't know what it was. Firefox seems slower, which could have caused?

  AVG wanted to bother with "Site display settings" Firefox or something like that, in order to use Firefox for my internet speed. I did accidentally and Firefox has seemed to become slower (or paranoid). I can't understand what AVG has done, and I hope that someone might know.

  Here's a Word to copy Word of what he said:

  "Firefox settings for the display of the Web site are not optimal for the selected in your profile or your computer Internet connection.

  Our recommendation: your browser settings must match your Internet connection and allow the performance of your computer for you to surf the Internet at the maximum speed possible.

  If you apply this recommendation, AVG PC TuneUp automatically performs all necessary optimizations for you. »

  So any ideas on what AVG could change?
  I will try to provide other necessary information.

  2. Click on the button 'Reset Firefox'.
  3. Firefox will close and reset. After Firefox is finished, it will display a window with the imported information. Click Finish.

• Why Firefox seems to zoom the web pages by default?

  Whenever I open firefox, the browser seems to be enlarged two normal steps.

  It causes blurred images and web pages to the different aspect of how I see them in my other browsers.

  Why does this happen? Thank you.

  If you press command + 0 or use view > Zoom > reset, restores the zoom level to the expected size?

  To set your zoom level by default than that specified by the stylesheet to the site, you usually have an add-on. For example, there is a named Default FullZoom Level and one other named NoSquint with this feature. You have either of those installed?

  Tools > Modules > category: Extensions

  If you have not already tried disabling use Firefox hardware accelerated graphics, go ahead and try that as well.

  You need to restart Firefox for it to take effect, so save any work first (e.g. you compose mail, documents online that you are editing, etc.).

  Firefox > Preferences > advanced > general

  Uncheck the "use hardware acceleration when available.

  If you restart Firefox, is improved clarity?

  Under Windows, you can set compatibility modes dimension screen in your Firefox shortcut, and that everything will appear larger. I don't know if this same concept applies to the Mac.

• Since I upgraded to 7.01 (linux xubuntu) firefox seems to crash, but only on the pages have something to do with Flash. I served flash and reinstalled and it seemed to fix, but is happening again today. Is there something I can do to fix this?

  I have Linux Xubuntu.
  I had 11.04, but upgraded to 11.10. bold text
  I've never had a problem with firefox until I upgraded to firefox 7. I've always made changes to about: config and went through my edits and none is related to this.
  I just checked on: fails and I had 34 accidents since the upgrade on 11.10.11
  Fix on the 13th, it seemed to me that there can be no planting until the 17th and it was through flash and then purge by reinstalling the necessary packages.

  I solved this problem by disabling hardware acceleration. At the time where I went down as my flash 10 (instead of 11).
  This option is no longer available. But disable hardware acceleration seemed to fix it.

• Windows Mail and browser FireFox seem frozen in time

  For a week, whenever I turn on my computer, the same e-mail to a date and time come in yet.  The messages that I had deleted from the deleted items folder are back there once again.  I've sent or forwarded messages are not in the "sent" folder.    I entered the server and delete these messages and prevents them from coming back, but the most recent messages are the same.  Whenever I turn on the computer, previously received messages come in, as if they had never been delivered before.

  Also, my browser, seems blocked.  Every time I turn on the computer, open the browser, I get the same error message - something cannot be found the page I looking for me and offers me a choice to try to reopen the tabs I had open the last time I used it, or to start a new session.  The tabs it offers me to resume the same each time - are apparently the same ones that I had opened every time that the incident that is causing all this trouble.

  In the last two days, I have done the disk cleanup and defragmentation, System Restore to a point before the date of the last post, I had received before this all started, checked with my antivirus (Avast Internet Security - the paid version) and have tried to remove my email and my browser of the 'Sandbox', a virtual environment, well that whenever I turn on the computer they are back in the sandbox.  The computer runs even slower he was before all this drama started.

  My computer is two years old and it runs Windows Vista.  No idea where to start?

• Firefox seems too high, she has no header and covers my taskbar and I have to restart the computer to get away. That's happened? I win 10.

  Hello

  I have a Dell inspiron with a 32 "screen. Operating system Windows 10.

  Watch a video on facebook using the full screen. It froze and has a strong low buzzing sound. I had to reboot, could NOT 'leave' back to the facebook page to leave that video. After turning the power back on, I opened firefox to go to facebook and discovered that I had zoomed in on firefox somehow and I can't see my task bar background nor and the header bar, or on part of firefox. IT DOESN'T TO ME ANYWHERE ELSE ON MY COMPUTER. I can use the browser Microsoft Edge and facebook is normal, works very well. Can use my Mozilla Thunderbird and it is fine. But every time I open Firefox, it is just too big for my screen as described above. Uninstalled and reinstalled firefox and was no help at all. Always do the same thing now, so I uninstalled again. I love firefox and never use another browser.

  Does he have already seen this before?

  Never understood what that was this corrupted file that Fred Mcd spoke, but I followed your link, Fred. And stumbling around in the help of mozilla, I found the part on updating firefox and who did it. He actually sent me a "assistant" who did the job when I clicked on "Finish".

  If Firefox is working again and my thanks to Cor - el and FredMcD

  The trouble hit when I was a video on facebook using the full screen. It froze and gave a continuous hum and I had to reboot. Trouble appeared then on Firefox. Weird how? But as I say, it's OK now.

  Once again thanks to you two.

• Mini Mac OS 10.8.5 - all settings, modules, etc. completely disappear to reopen after closing firefox (seems completely reset)

  I tried as much as I could find to fix - firefox is not set to reset the story with each new reboot, and I was by the audit of the my file is not locked in the profiles. I do not have a lot of folders and files - prefs is this normal to have several of them. At one point I tried to remove all except one of them because I read here that it would be creating a new file automatically. He did, I checked that it was unlocked, but still, at each closing Firefox, everything gets reset as if I just download the program. Any ideas?

  Using the latest Firefox for my os on a mac (just deleted the old and downloaded it again today).

  Thank you

  Try to remove the file profiles.ini (i.e. move the folder to the trash).

  You can also delete all the folder in the profiles folder that Firefox was created because he wasn't able to safety profile for the file profiles.ini file.
