Suddenly in both ff 3.6 and beta 4 all of my add-ons are gone; they are all listed on the add-on page but they are not on the browser--help!
One day when I opened ff all the add-ons had disappeared. I've uninstalled ff and re-installed. I've installed beta 4. I've uninstalled some of the add-ons and re-installed them...nothing makes a difference. I tried deleting extension configuration files in case they were corrupt (per support page)...no help. I'm using Chrome right now but I want my firefox back, I miss it so! Can anyone help me?

Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox profile folder to reset the extensions registry. New files will be created when required.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the "Find Updates" button (in Firefox 4: right-click the extension -> "Find Updates") to do a compatibility check.
