Until Firefox 2 it was easy to copy and paste Firefox profiles from one computer to another. You just had to copy and paste the profile folder - more or less. I now tried the same again for Firefox 3 and I did not succeed now for many hours; I've looked up the web for support, looked for extensions. But to no avail.
But finally I got it and need to share it immediately. In fact it's quite easy (tested for migrating my Firefox profile from a Vista to a XP machine):
On the computer with the Firefox installation to be copied:
- Open your profile folder (easier whith the add-on " open profile folder ")
- Close Firefox (that seems to be important)
- One step ahead in the file explorer
- Copy the whole profile folder (named something like rgnrgnrgnrgn.default; "rgn" is a r andomly g iven n ame)
- Install Firefox.
- (Run Firefox & close Firefox)
- Open the Firefox profile manager by typing "firefox.exe -p" or "firefox.exe -profilemanager" in the command line (Start > Run/Ausführen)
- Create a new profile
- Uncheck "Don't ask at startup"
- (Do not start Firefox by now)
- Find the new profile in your file manager (it's named rgnrgnrgnrgn.newprofilenamefromstep5)
- Copy and paste all the contents from your profile folder from the "old" firefox installation into this new profile folder. If asked: Overwrite any file.
- Now start firefox via the profile manager by choosing your new profile.
- :-)
Finallly some paths to find your profile folders:
