[Solved] [sort of] Firefox add-ons giving NS_ERROR_FILE_ACCESS_DENIED, dual-boot

[chconnor]

Hi - thought i'd post this in case it was useful to anyone else. I dual-boot windows and 10.04, and after the upgrade Firefox wasn't working so well.

First i had to fix it up with: http://mozillalinks.org/wp/2010/05/b...with-noscript/

But i was still getting add-on update and installation problems, including a message in the error console including "NS_ERROR_FILE_ACCESS_DENIED". I didn't want to wipe the profile. Couldn't make it work, until i realized that it had something to do with the profile being on an NTFS partition (saw the same thing on another computer with the same setup). I never did sort that out, and i didn't try it on a shared FAT32 partition, but i was willing to sacrifice the shared profile setup (especially since the repository FF version never keeps up with my windows version anyway, and running two versions of FF on the same profile gets old), so i simply copied the profile into a newly created directory:

cd ~/.mozilla/firefox/
mkdir mynewprofiledir
cp -r /windowspartition/path/to/previously/shared/profile/dir/* mynewprofiledir/.

(you can figure out the previous profile path from the profiles.ini file, if you need to)

Then i edited the profiles.ini file to include a new entry:

[Profile5]
Name=mynewprofilename
IsRelative=1
Path=mynewprofiledir
Default=1

(note: i used Profile5 because profiles 1-4 existed already; number yours accordingly)
(also find whichever other profile has Default=1 and remove that line for that other profile)

Then i started firefox from the command line:

firefox -ProfileManager

...selected the new profile, made sure that the appropriate check box was checked to make this the new default (can't remember how they phrase it), and was good to go. Half-installed add-ons finished installing correctly, new add-ons installed correctly, etc.
