Firefox opens PDF but cannot save browsing history, how to deal with it
If you have sync, and there is a problem anywhere, Shut Down Sync Immediately On All Devices to prevent the problem from spreading. Once the problem is fixed, perform the same repair on all computers/profiles before using sync again.
[v57+] Places Maintenance is built into Firefox.
Type about:support<enter> in the address bar.
You will find Places Database near the bottom. Press the Verify Integrity button.
When done, copy and post the results here.
