I have been a portable firefox user for quite some time now, and Ive experienced this for the third time now.
On these rare occasions, my firefox wont load any of my addons including extensions and skins. I keep maybe only two or three themes, but extensions... well i would say i had a good 50+ I use, and i find all of them usefull. After the second happening of this i started keeping bookmarks of the extensions donwload pages, even tho its a huge hassle to install each one of them again. Pretty much firefox just loads up everything but my addons, and when it happens the first time, it nvr loads my addons again, leaving only one solution, to completly delete and reinstall my firefox following exporting my bookmarks. I checked the firefox folder and found some files which i recognize to be extension files, and i can tell because of the space used by the portable firefox folder (currently 77mb) and so its obvious that all my extensions are still there. I still have plenty of space left on my usb (about 200 mb free) so i doubt that has to do with it. Im assuming its just too many extensions for firefox to load, but idk why it happens when it loads them perfectly fine plenty of times before.
I'm not sure if i have just been repeating myself, but i hope you understand my problem. Im currently holding off on reseting in hopes of not having to reinstall all over again, and possibly finding a way to prevent it happening again.
