Cannot install extensions that existed before a reinstall
Hello, I originally installed Firefox in my work laptop and logged in to sync my stuff. Due to some company policies, I had to uninstall it. Eventually, I was able to overcome some oddities and finally could reinstall Firefox. But when I logged in, sync was neverending (matter of hours, if was just stuck); thus I refreshed it, but no luck whatsoever, still neverending sync. Tried a few refreshes and reinstalls until eventually everything was fine.
Unfortunately, during this process something must have been damaged as I lost most of my extensions and themes. So I decided to reinstall them one by one. For some of them everything went just OK, but some others (e.g. FoxyTabs) cannot be installed anymore, see screenshot. The path is:
- Click add button
- confirm I want to add the extension
- that error is shown (translate from italian: An unexpected error occurred during the installation)
I really don't know what to do. Did my Firefox installation get corrupted or what?
Thanks a lot!
