ProfileSwitcher

This extension makes easier to use more profiles in Firefox and Thunderbird.
It adds also in the File menu two new items to start another profile or the profile manager. From the extension's preferences, you can choose what to do when you launch another profile (close the one in use, don't close it, ask every time - If you choose to run the profile manager in safe-mode, the current profile will be always closed).

Moreover it can add the name of the profile in the titlebar or as icon in the statusbar.

Notes:
- from the 0.1.3 version, it works properly also if you install it globally in the program directory;
- 0.3 version or higher, compatible with Firefox/Thunderbird 2 or higher, works properly on every operative system, without limits, and doesn't use launcher scripts;
- from 0.3.3 version, on Thunderbird, profile's name is added also in addressbook window.

At the present the extension is localized in italian, english, german, french, polish, portoguese, hungarian, dutch, swedish, chinese, serbian, romanian. Some locales could be not complete. If you are interested in traslating the extension in other languages, please do it through Babelzilla project

Note for firefox-3.5 - ubuntu version - users: ubuntu users that have firefox-3.5.X packaged by ubuntu, could need to create this symbolic link:

ln -s /usr/lib/firefox-3.5.X/firefox-3.5 /usr/lib/firefox-3.5.X/firefox

where X is the number of firefox subversion.
