I am facing two issues with Firefox. I am using Firefox on Macbook Pro 2017 with i7 processor and 16GB Ram, but after importing all my bookmarks from chrome its laggy like when i move mouse hover the bookmarks its animation response time is slow ie :- Moving cursor up and down the blue animation strip its bit delay comparatively mouse cursor movement.

Secondly i am having issue with YouTube, when i am double click on YouTube video to full-screen its give blank screen for a sec its bit annoying i think it need to fix.

The issues you describe can be caused by a problem with the places.sqlite and favicons.sqlite databases in the Firefox profile folder.

  • use "Verify Integrity" button on the "Help -> Troubleshooting Information" (about:support) page

If errors are reported with "Verify Integrity", close and restart Firefox and retry.

If "Verify Integrity" cannot repair places.sqlite, rename/remove all places.sqlite and favicons.sqlite files in the Firefox profile folder. Firefox will rebuild places.sqlite and restore the bookmarks from a recent JSON backup in the bookmarkbackups folder.

  • keep a backup copy of places.sqlite in case a new places.sqlite database has to be created

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

HI Iqubal Singh

When you wrote "Hey FredMcD i already did this drill" does that mean you tried Firefox Safe Mode as Fred suggested?
