I use FF both at home and work. I use same profile and let FF to synchronize everything - however, for work purposes, I need some other add-ons, which I don't want to get synced to my personal computer. Solutions currently available: - Turning synchronization of add-ons off - but then I would have to keep track of what is installed for each FF installation I use - Creating new profile for work - but then I have to keep track of bookmarks, passwords, site settings, ... It would be great if I could install add-on locally (disable syncing for it) (... could be similar to making add-on available in private mode) Is there such option somewhere? If not, how can I turn it to feature request?
