Updated for FireFox 11 and I keep getting "compatibility check Add-on" when I launch the browser.

I've just updated to FireFox 11 and whenever I run the browser, I get this annoying window that checks for compatibility of modules.

I looked for solutions and have tried the following:
1 remove several extension files in the profile folder.
2 returning to about: config to disable the extension: checkcompatibility (is not here).

None of them worked.


Have you tried to delete the prefs.js file?

What security (firewall, antivirus) software do you have?

Some security software has features of virtualization that can cause protection problems and restoring files in the Firefox profile folder.

  • is it possible to STOP firefox open a tab to perform a check of plugin, everytime I open the browser? I LIKE the version I have and find the additional delay caused by this to be quite frustrating

    as stated in my opening 'Summary' sentence/question...i'm becomes more and more annoyed by an additional tab (plug-in check) opening whenever I open firefox... I have plug-in versions that I WANT and I DON'T want or don't need to push me to update or to change them whenever I opened a window of browser... I've searched and searched and so far I have found no way to prevent this and was really hoping that someone could provide me with firefox a method to stop intrusive loading page again and again...

    I have uninstalled Viewpoint Media Player, that fixed my problem with tab plugincheck still of the opening. Viewpoint Media Player is responsible for the plugin called "MetaStream 3 Plugin r4", and I think this plugin is the outbreak of Firefox to open the plugincheck page. It is not enough to disable the plugin, it must be uninstalled.

    Since it seems that you do not have the "Plugin for MetaStream 3', it may be that some other plugin is at the origin tab plugincheck opened pop. Try to go to (menu) tools-> Add-ons-> Plugins. See the list of plugins and see if any of them have an icon of red warning next to them. If one of the plugins has a red warning icon, it may be responsible for the outbreak of the opening of the plugin tab. Try to uninstall this plugin, or upgrade to a newer version.

    It does not properly detect some most likely SSE extensions, but don't let it stop you. It's just a side effect of computers becoming too recent for 3 year old software. Even if in strictly technical terms, there would be a performance degradation, reinforced specs of the newest processors would more than make up for it...

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

    See "basic troubleshooting: a new profile:

    There may be extensions and plugins installed by default in a new profile, so check that in "tools > Modules > Extensions & Plugins" in case there are still problems.

    If this new profile works then you can transfer files from the old profile to the new profile, but make sure not to copy corrupted files.

  • Portege M700: Cannot use the fingerprint reader after update for Firefox 3


    I have a Toshiba Portege M700 Tablet and with the truesuite software on a fingerprint reader and password Bank plugin.

    It's all working fine and dandy with firefox 2.
    Then last night I went and updated for firefox 3 and now I can't log in to Web sites with the fingerprint reader.

    No error messages, nothing. I can say that the truesuite or Bank password software is not detecting firefox 3. I've updated to the latest version that I could find,

    I found this thread by telling me the process of update of firefox it breaks and I should completely uninstall and reinstall firefox, which I did.
    That didn't fix it.

    Then I completely uninstalled and reinstalled truesuite. That did not help either.
    Its still broken.

    Anyone know a workaround or a way to fix this, or should I wait and see if there is an updated version of the password database? (I find it unlikely because this isn't really a standard program)


    I think that the new Firefox version is not fully tested and possibly it s not completely compatible with the 3rd party applications.
    I remember the same problems with older versions of firefox. Finally, it has been resolved.

    But why you don t use internet explore? As far as I know the fingerprint works without a problem

    In any case if you want to continue to use the browser firefox 3 so I think that the only solution is to wait for an update.

  • Downloaded the update for Firefox, and now I can't get rid of AOL.

    Downloaded the update for Firefox, and now I can't get rid of AOL. I tried to remove anything that is related to AOL and when restart Firefox... There are once again AOL. I even reinstalled Firefox... He was there again.

    Where AOL is displayed - homepage?

    I think the first thing to check is if you have any modules related to AOL. These can replace your regular settings. You can view and disable all extensions essential or unknown here:

    Firefox orange (or the Tools menu) button > addons > Extensions category

    Note that in most cases, you should use the link to restart Firefox to actually disable the extension that you have chosen to disable.

    Then, to fix your homepage, try the procedure described in this article: How to set the home page.

    If there is a problem with your suppliers of research from Google for AOL, try this extension:
