Firefox always checks compatibility

Hi, ever since installing latest version 10, every time I open Firefox I am getting 2 tabs, one start page and one with the 'checking compatibility of add on's' how can this be stopped Bill

sorry for late reply, was abducted by aliens I managed to escape and back now. I use Online Armor firewall and Emsisoft anti virus, Ive recently upgraded this amazing software as they brought out a newer version, this could be the problem as now I think about it my Firefox problem was around the same time. I will check out the Emsisoft community forums, hope that brings some answers but in the meantime thanks to everyone that has taken the trouble to help

  • How i can stop Firefox to check compatibility ?

    i have two version of Firefox and have two different problem that when i close one and open another then i found that they spent some second on checking compatibility of plugins so if i can stop them to check compatibility then how i can.
    second thing is that are i can install plugin for separate version. like a version of Firefox have support this version of plugin and it's probably not sure that same version of plugin support in another version of Firefox.
    so their is two queries i have about Firefox.
    How i can stop Firefox to check compatibility of plugin everytime when i open them.
    How i can install plugin in Firefox separately then their is no need to install them again when i open another version of Firefox

    You need to use separate profile folders for each version. Firefox will perform a compatibility check and recreate all cache files if you switch versions.
    Create a new profile exclusively for each Firefox version and create a desktop shortcut with -P "profile" appended to the target to launch each Firefox version with its own profile.
    See these mozillaZine KB articles for information:

    * http://kb.mozillazine.org/Shortcut_to_a_specific_profile
    * http://kb.mozillazine.org/Using_multiple_profiles_-_Firefox
    Do you mean plugins (Tools > Add-ons > Plugins) or extensions (Tools > Add-ons > Extensions) ?
    Extensions can easily be installed if you use separate profiles. Firefox 4 will also recognize plugins that you install in the plugins folder in the[http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder], but you need to create that folder yourself and copy the plugins files to it.

  • Firefox checking compatibility of add-ons every time it starts.

    Every time I upgrade, Firefox begins checking compatibility of add-ons every time it starts. And it brings up the "Hooray! Your Firefox is up to date" page every time too. How to fix?

  • "Checking Compatability of Add-ons" Update window at each startup & redirects to a welcome page. Tried disabling all add-ons & updates / force compatability checker. Thoughts?

    Each time I start Firefox a "Checking Compatibility of Add-ons" update window appears, which redirects me to a welcome to Firefox 5.0 page with my normal home page in another tab. I tried disabling all add-ons and updates as well as the force compatibility checker. I think my AVG safe-search bar might be causing the problem, but I have it disabled and never use it. Please help me get rid of this.

  • How do I get Firefox to check addon compatibility first, then ask me if I want to continue the Firefox update?

    How do I get Firefox to check add-on compatibility first, then ask me if I want to continue the Firefox update? The update process currently only tells me that an add-on has been disable after applying the Firefox update. The Options > Advanced > Update tab switch, "Warn me if this will disable any of my add-ons", does not seem to work.

    How do we check that new versions of FF are compatible with our existing Add-ons? I'm really quite over always having half of them not working after updating FF. It's very frustrating. Couldn't there be an option in the Add-ons menu that checks if they're compatible with a new version? Thanks.

  • Checking compatibility of add-ons always running after update

    After updating Firefox to version 6, the checking compatibility of add-ons is always running with each start of Firefox, and "Welcome to Firefox" site is always opening as well.
    This is very disturbing.

    Apparently I wasn't clear or the word upgrade wasn't right. I meant going from 4 to 5. I downloaded it, installed it and got no option resembling that at all, it just saved a DMG to my hard drive and then told me to put it in my applications folder as always. I opened it and that was that, no compatibility check. I already got one error about an add-on that's vital. I'd backed up before I installed and saved Firefox 4 as a separate file before opening 5, I hope I'll be able to go back to it. The old system was really much better, what's the point of finding out after you already installed something if your systems will work? Or of avoiding installing because you're afraid they might not when everything very well might be fine? I can guarantee you that I won't be installing an major updates for a very long time, that's for damn sure.

  • How do I completely disable initial "Checking Compatibility of Add-ons" pop-up for all users on a Citrix server where the FireFox was upgraded to 29.0.1

    I have a set of Citrix servers, we need to upgrade the FireFox on them to 29.0.1
    When I have done this, and a user runs FireFox, now the users are being presented with a pop-up "Checking Compatibility of Add-ons" which delays the start of FireFox.
    I need to prevent this so users just see FireFox start up without any delays.
    I have installed the add-on that re-enables extensions.checkCompatibility and tried various ways of implementing it like pref("extensions.checkCompatibility", false);
    However we seem to have a situation where the add-on that enables the setting is not loaded yet so the setting is not implemented.
    How do I solve this for all users?

    You can try to set the browser.startup.homepage_override.mstone pref to ignore on the about:config
    *http://kb.mozillazine.org/browser.startup.homepage_override.mstone
    You can use a mozilla.cfg file in the Firefox program folder to specify new (default) values and possibly lock prefs.
    Place a local-settings.js file in the defaults\pref folder where also the channel-prefs.js file is located to specify using mozilla.cfg.
    pref("general.config.filename", "mozilla.cfg");
    These functions can be used in the mozilla.cfg file:
    defaultPref(); // set new default value
    pref(); // set pref, but allow changes in current session
    lockPref(); // lock pref, disallow changes

    How to stop Firefox from checking for add-on compatibility every time it opens?

    That can be a problem with the compatibility.ini file in the Firefox profile folder.
    Try to rename (or delete) the compatibility.ini file in the Firefox profile folder to see if that helps.
    You can use this button to go to the currently used Firefox profile folder:

  • After updating firefox the first window after opening first time "checking compatibility of add-ons" window is froze won't progress pas 1/3 of completion

    I updated my fire fox on my MAC OS X to 3.6.6 version of firefox, everything went smooth till I open FireFox then the window firefox update opens up and about 1/3 through the process it gets stuck on Checking Compatibility of Add-ons and doesn't go any further. I have hit cancel and firefox opens but it doesn't open any web sites. I have removed firefox and re-installed and it is still doing the same thing. I have also let it run over night thinking it may just take a while and it never progresses, please advise, I am new to MAC but FireFox is the only browser on my mac that will open one of my business pages, known issue with mac for this company.

    I am not clear what your problem is and importantly whether you are trying to ask for help with Firefox.
    If you have a Firefox problem can you explain what you need help with please. If the problem is with a new Windows 8 operating system you will need to find a suitable forum to discuss that.
    A websearch will turn up many suitable fora one possibility is

    The people who answer questions here, for the most part, are other Firefox users volunteering their time (like me), not Mozilla employees or Firefox developers.

  • Why does "checking compatibility of addons" come up each time I turn on Firefox?

    Each time I turn on Firefox a box comes up with "checking compatibility of addons".

    It is possible that there is a problem with the file(s) that store the extensions registry.
    Delete the files extensions.* (e.g. extensions.sqlite, extensions.ini, extensions.cache) and compatibility.ini in the Firefox profile folder to reset the extensions registry.
    *https://support.mozilla.org/kb/Profiles
    New files will be created when required.

    *https://support.mozilla.org/kb/Unable+to+install+add-ons
    If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to do a compatibility check or see if there is a compatibility update available.

  • Why doesn't the auto update to my Firefox always hang up when it is checking compatiblily with my addons?

    Towards the end of an automatic Firefox update, the program opens a dialogue box that says it's checking compatibility of the new version with my addons. It also mentions that I should be patient, that the process could take several minutes. The process continues without normal termination, and I have to use Windows Task Manager to stop it. I've let it run form as long as 35 minutes, but it never completes the process. This has happened for each of the last 3 or 4 auto updates. What's going on?

    We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.
    #Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
    #In that text field, enter %APPDATA% and press Enter. An explorer window should open.
    #From that explorer window, double-click on the ''Mozilla'' folder, then double-click on ''Firefox'' and then on ''Crash reports''. Double-click on ''submitted''.
    #Now, you should see a list of files that contain reports. Go to ''View'' > ''Arrange Icons by'' > ''Modified'' to get the most recent files at the top of the window.
    #Open the most recent 5 files with a text editor and copy the IDs.
    #Paste each ID with '''bp-''' into the reply window on the forums.
    Thanks in advance!
