Every time I start Firefox it repeats the add-on compatibility check
I understand the need to check compatibility with newer versions of Firefox. But in my installation (FF4) , it performs this check EVERY time I start up Firefox, and - as the message says - it takes several minutes.
After this check, everything works fine, inclusive all my plug-ins
Previous versions did not have this problem.
I tried already setting all copmpatibility settings to false: extensions.checkCompatibility.4.0 false
and so on
Is anything else casuing this check at startup of Firefox?

Make sure that you do not use that profile folder with other Firefox versions.

Use the advanced config editor (about:config), look for plugins.update.notifyuser and double-click it to set it to FALSE.

Thank you for this suggestion; however, this setting was already set to false, and nevertheless the check is started avery time I start Firefox
That check can be caused by the presence of outdated plugin or by some specific plugin like the The "MetaStream 3 Plugin r4" plugin.

i had this problem too. in your C:\Users\yourname\AppData\Roaming\Mozilla\Firefox\Profiles\yourprofilename directory you will find a file called "user.js". i had upgraded from firefox 6.0.1 to 6.0.2, but for some reason this file did not get updated properly. using notepad i edited this file and changed all references to 6.0.1 to 6.0.2 instead (change your version number as appropriate of course). that fixed the problem for me.
Thanks to Cor-el posting. I follow the link and read the information provided in the Preferences Not Saved page. In my case I found that the users.js was locking certain preferences. I follow the instructions and proceed to delete the users.js file in my Firefox profile directory. I re-launched firefox and the add-on compatibility check did not repeat again.
