  Thank you very much for your help!

  More information and additional troubleshooting steps are in the article Firefox plant - troubleshoot and prevent assistance fixing crashes .

  ________________________________________________________________________________

  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).

• I get a saying of popup, that I need to install software to make sure that my browser is the latest version, but I already have firefox 28.0 and I am bit suspicious.

  I just started having this extra window that says: "RECOMMENDED updates! It is recommended to install the software to make sure that your browser is the latest version. Please update to continue. "The link says: Rvzr - a.akamaihd.NET. I'm a little reluctant to touch anything because it never happened. In addition, I've doubled checked and my firefox is 28.0 isn't up-to-date. I even re-downloaded firefox to ensure, and I always get the pop-up window.

  You're smart to be wary. You can check to see if an unnoticed add-on slipped? In particular, I suggest disable all non-essential or unrecognized extensions on page modules. Either:

  • Command + shift + a
  • Tools menu > Modules

  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.

  That get rid of the nagging dialog boxes?

  -Microsoft got a big update last night for the Windows 7 and I came this morning I was wondering if the update would help my FireFox. I thought it might because a lot of things in this forum said it was a security problem and they have been updated with security updates. SHAZAM! Firefox is now the new my browser to goto. Very happy to resume. Once more I did anything this morning, but click the icon after the big windows 7 update and we're back in business. Thanks for all your help!

• I updated to Firefox 8.01 and confirmed that it is the current version. However, both Google and Firefox do not recognize my current verision - these sites indicate that my version is 3.5.7. Why?

  I've updated (more than once) to Firefox Version 8.01. When I check the Firefox Help: About, it confirms the version number and indicates that it is the current version. Google, however, when I try to use G-Mail or + Google, gives me a message that my version of Firefox is no longer supported (and provides a link to download the current version). In addition, Firefox itself, when I tried to use the help: menu option to submit your comments, indicates that I can't use this option until I first updated to the current version. Apparently, even though I've updated, there are some markers or indicator, which is not updated since a previous version to indicate which version of this browser Web sites is running on my computer. I would like to get this resolved, because it prevents me from doing a few things I want to do. Furthermore, I just watched the dialog below, following the comment "we have made some assumptions about your current browser...". ', also indicates that my current version is the 3.5.7.

  You have a pref general.useragent.override that identifies you as Firefox/3.5.7

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

  • C:\Program Files\Mozilla Firefox\
  • http://KB.mozillazine.org/Installation_directory

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

  • ESR 10.0.x Firefox: http://www.mozilla.org/en-US/firefox/organizations/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.

• WHY don't images suddenly appear or show in my gmail messages using Firefox 12.0 AND 13.0 but I can see the beautiful in IE9?

  WHY don't pictures suddenly not appear or display in my personal messages gmail using Firefox 12.0 AND 13.0 but I can see the beautiful in IE9? This isn't a problem with the images being seen on Web sites or in emails from various sites like Amazon, Bloomies, etc.. It is a problem with the images, copied and pasted while composing mail in GMAIL and the other Windows Live email accounts, etc. It started suddenly yesterday when I still had version 12.0 Firefox. (there may be a few days, but I hadn't been reading emails too for a few days due to time constraints). This morning I tried to find some fix for this by searhcing constantly through the web and through the forums of Firefox here. I checked my version of Firefox and also check for updates after about 2 hours of research from the forums without success and I was about to just get rid of Firefox 12 because some people were just that frustration with finding no solution, when suddenly, I got a message from Firefox 'urge' Update update me Firefox 13. It was AFTER I had just checked an hour earlier to see if there's an update! I did this update to version 13.0, BUT again, I do not receive emails containing images with these images posted (messages sent from my other e-mail account for myself and also e-mails to a friend - the two images containing). However, I can send and receive your same emails through IE9 in my gmail account and see all of the images of the FINE through IE9. What gives? I am so tired of what's going on. It happened before about a year or two ago, but I do not remember how it was corrected for ever. According to me, it has been resolved by a Firefox patch, and no action on our part. And these 4 + hours of work on that is just crazy. WHO has that kind of time to devote to fix these defects that occur every time updates of Firefox? I can not even find any mention of the same show. Now I'm seriously behind. You talk about time constraints! Anyone else having this problem? Someone at - he found a cure yet?

  Is he missing pictures then make sure you are not block images from certain domains.

  • Check the permissions for the domain in the active tab in "tools > Page Info > Permissions.
  • Check that the images are enabled: Tools > Options > content: [X] loading images automatically
  • Check exceptions in "tools > Options > content: Load Images > Exceptions.
  • See the tab "tools > Page Info > media ' for blocked images (scroll all the images with the cursor key).

  If an image in the list is grayed out and there is a check mark in the box "block Images of..." and remove this mark to unlock the images from this area.

  Make sure that you do not block the images of third parties, the pref permissions.default.images must be 1.

  • http://KB.mozillazine.org/Images_or_animations_do_not_load

  There are also extensions (Tools > Modules > Extensions) and security software (firewall, antivirus) that can block images.

• browsers (IE8, Firefox, Google Chrome and Opera) 32-bit and Vista 64-bit

  Hello

  I have a HP Pavilion dv2842se. I've had a little more than a year. IE 7 was originally installed with a version 32-bit and 64-bit. Not long after that I got it, the 32-bit version stops working. More specifically, as soon as I open the program it would be closed and completely unusable. I couldn't understand the question, so I installed Mozilla Firefox 32 bit and just used that. When the update of IE 8 came out, I downloaded and still had the same problem, so I continued to use Firefox.

  With the help of Mozilla has worked for me until about two weeks ago, when Mozilla started to become more and more reliable and now completely unusable. Assuming that it was a specific problem of Mozilla, I downloaded the 32-bit versions of Chrome and Opera and finished with all versions of four 32-bit navigation programs are the same.

  I realize that I can simply use the 64 bit version of IE8, as I did since I have no choice. However, there is a big problem with this. IE8 does not support Adobe Flash Player, which is required to run virtually all Web sites - including on the main site I use for my college classes. As the main reason that I bought this computer was for College, my computer as a whole is pretty useless to me without a functional browser that supports Adobe Flash Player.

  By the statement of HP, I tried to disable all add-ons, reset all internet settings and uninstall then reinstall Adobe Flash Player. I even on my own I've tried a system restore and scanned for viruses, spyware and software malware. Nothing has worked.

  Please, please, please if there is absolutely everything I can do to restore my browsers 32 bit in a usable state, please help me. I really do not have the money to buy a new computer, and 64-bit operating systems are almost now - standard, so there is no saying that if I bought a new computer for the same thing does not happen everywhere.

  Thanks for any help you can provide! It is much appreciated!

• My laptop crashed and when I turned it back to firefox was updated and my favorites have disappeared

  Hello

  It seems that you have updated to the version of the developer, so please see this support article:

  • https://support.Mozilla.org/en-us/KB/recover-lost-bookmarks-Firefox-Developer-Edition

• on the home page, the symbol of firefox has disappeared and there is an ad for registry cleaner?

  Yesterday, my homepage has changed - there is no normal firefox symbol with the little Fox hug th Earth. Just four color wheel, next to him "search results" then the field empty to enter in a search. Below that is an ad for a registry cleaner. It presents the new homepage of firefox?

  Hello, this looks like a problem maybe caused by adware on your pc. Please go to firefox > addons > extensions and remove any suspicious entries (toolbars, the things that you have not installed intentionally, I don't know what purpose they serve, etc.). also, go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there and run a full scan of your system with the security software you have in place and various other tools such as the free version of malwarebytes & adwcleaner.

• Firefox stop working and I can't even open the profile page to create another profile and start the migration to a new profile, what to do now?

  I can't get firefox to respond - even to open. I tried the suggestion of support for the creation of a new profile, but the instructions are not working anymore so I can't create a new profile and test the system. I don't want to lose my info saved thanks to a re - install if I'm not even sure that it will work - if the data is corrupted. whatever that means.

  At a stand still...

  BTW - since I have to use IE even access this info I can't find the troubleshooting information below. It gets ridiculously more complicated that I never wanted him.

  Some Firefox problems can be solved by performing a clean reinstall. This means that you remove Firefox program files, and then reinstall Firefox and won't lose bookmarks and history. Please follow these steps:

  1. Download the latest version of Firefox from http://www.mozilla.org office and save the installer to your computer.
  2. Once the download is complete, close all Firefox Windows (click on quit in the file menu or Firefox).
  3. Remove the Firefox installation folder, which is located in one of these locations, by default:
     • Windows:
       • C:\Program Files\Mozilla Firefox
       • C:\Program Files (x 86) \Mozilla Firefox
     • Mac: Delete Firefox in the Applications folder.
     • Linux: If you have installed Firefox with the distribution-based package manager, you must use the same way to uninstall: see Install Firefox on Linux. If you have downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
  4. Now, go ahead and reinstall Firefox:
     1. Double-click on the downloaded Setup file and go through the steps in the installation wizard.
     2. Once the wizard is completed, click to open Firefox directly after clicking the Finish button.

  Please report back to see if this helped you!

• Linux, Firefox 21.0 and the last flash for LINUX (11.2). I can't view youtube videos because firefox has disabled the plugin. Help!

  An hour ago, I watched with happiness of the videos from youtube on Linux using Firefox 20.0 and 11.2 flash. I've just updated firefox and it of now my blocking flash and invites me to update. The problem is I can't update because 11.2 is the LATEST version of the flash for firefox plugin, there is no other version.

  Is there a way to prevent the deactivation of my firefox plugin?

  The directory structure, at least for linux, seems to have changed for version 21. I have my distribution of firefox / opt/firefox /, and so far I keep the plugin flash in/opt/firefox/plugins /. Verse 21, the plugin directory should be/opt/firefox/browser/plugins/EC directory does not exist by default. You can create or mv just the old directory of plugin to the new location

  $ cd/opt/firefox / #(ou partout où votre firefox est installé)
  $ mv plugins / browser /.

  Icons / directory has also been moved to that subdirectory, that's why my office firefox button was not correctly displayed after the update.

  -The main thing that firefox really should do is to archive the previous version of firefox, whenever there is an update. It is ridiculous to have to deal with this kind of issue immediately after an update when you have important work to do on time! To do a simple option to temporarily return to the previous version of firefox. It would be trivial to implement and could be used when a new release breaks something.
