Add - ons do not appear in the toolbar since I switched to Firefox 4?

No they are not disabled. I use win7 32

You can try:

This can also be a problem with the files that store the registry extensions.

Delete the files (extensions.sqlite, extensions.rdf, extensions.cache, extensions.ini) extensions.* and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created if necessary.

See "extension corrupted files":

If you see people with disabilities, is not compatible extensions in "tools > Modules > Extensions ' and then click the Tools button, on the left side of the search bar (or click on the"Find updates"button in older versions of Firefox) to do a compatibility check or see if there is an update.

  • Webutation extentsion will not appear in the toolbar

    installed webutation extentsion... will not appear in the toolbar...

    I checked the Webutation extension and this extension is broken because it uses a function (quote() to quote a string) that is no longer supported in Firefox.

    This is not a bug in Firefox, but a bug in the extension and thus must be fixed by the creator of the extension.
    You can point the creator of expansion on the subject if you wish.

    I don't know for other extensions, but they can be broken as well and you will need to check the Console browser (Firefox/tools > Web Developer) for the error messages.
