I have Firefox ESR 60.8 on Windows 10. In the bookmarks toolbar, I see some bookmarks that were synchronized from another computer through my Firefox web account. But, I cannot make any changes to my bookmarks:
- I cannot bookmark new pages. Clicking the “bookmark” star does nothing – the star remains white instead of becoming yellow as it should.
- I cannot even move bookmarks in the existing bookmark toolbar.
- When I change bookmarks in the other computer, the changes do not synchronize to this computer.
What I tried:
- Refresh Firefox;
- Start in safe mode;
- Delete the file “xulstore.json” in the profile folder.
None of these helped. How can I fix it?
