See the upstream bug report. They say it's due to a previous bug. I've sent them the requested files, but no answer yet.
I've even ended up with some extensions in the state "get updated/removed/installed after Firefox has been restarted", but they did not change after restart. So I removed my "extensions" directory and re-installed the extensions I want (and discovered some new ones :)) I don't need the patch now anymore. Seems like there's been some internal corruption. -- "installLocation has no properties" error in nsExtensionManager.js during install/update of extensions https://launchpad.net/bugs/65609 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
