The new profile did have the correct version number. Resetting the general.useragent.extra.firefox value in my own profile fixed the problem.
I checked my backups and the general.useragent.extra.firefox value was modified Ant.com Video Downloader addon a long time ago while I was using Jaunty. I think this caused the general.useragent.extra.firefox to be marked as "user set" and not updated to reflect new versions (I'm assuming "user set" values in about:config are not changed by upgrades). Even after I uninstalled the addon, the version number was never changed through two Ubuntu and Firefox upgrades. Thanks for your help. -- Firefox user agent reports wrong version number -- 3.0.6 instead of 3.6.3 https://bugs.launchpad.net/bugs/580352 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
