Sometimes I need to use Firefox with a lot of different settings (like turn off several addons and change some settings to get a lower bandwidth usage).
I have the idea of having multiple profiles for that. So far, so good. But what if I want the profiles to share the history, bookmarks, open sessions/tabs, saved passwords, input field history and so on - everything except addons and config?
My actual idea is to copy the existing profile and symlink some files to the "main" profile.
Do you have a better idea to do that? Firefox Sync isn't an acceptable solution since it doesn't synchronize open tabs (it says it does, but it rather saves the open tabs as bookmarks). If symlinking is the only solution, which files do I have to symlink?
