I use Whonix and run the Tor Browser inside it. Whenever a Tor Browser update appears, I often encounter problems afterward. To avoid this, I copy my profile.default folder before updating and then restore it if the update causes issues. That has worked until a few days ago: I updated my tor, restored (copy-paste) my profile.default as usual, but this time it still produced an error.
the bookmarks and history system will not be functional because one of tor browsers files is in use by another application. some security software can cause this problem.
i did many things and can not solve it.
