Whenever I click on 'bladwijzers' (bookmarks) my installation of Firefox hangs. What can I do about this?

Each time I click on 'bladwijzers' (bookmarks) my firefox hangs. After a while it becomes responsive again and I can continue using it, but it happens every time. I have no clue what causes this.

I do have a lot of bookmarks though. They used to be in folders and everything, but those seem to be gone. I have 'refreshed' Firefox, but I'm reluctant to reinstall firefox, because I'm afraid I will lose all my tabs and windows and bookmarks. Without plugins the problem persisted.

I'm running the latest version of Firefox (59.0.2) on the latest version of macOS (10.13.4) on a iMac 13,1.

How do I delete Firefox and keep al my tabs and windows? I'm quite addicted to Firefox and keep a lot of stuff open and I would like to be able to just continue where I left off.

I hope all this is a bit clear. Thanks in advance for any suggestions, tips and tricks.

Chosen solution

If you use Sync then best is to disconnect Sync temporarily during troubleshooting.

You can check for problems with the places.sqlite database (bookmarks and history) in the Firefox profile folder.

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

See also:

If "Verify Integrity" on the "Help -> Troubleshooting Information" (about:support) page cannot repair places.sqlite then remove all places.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.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

Firefox comes in two or more folders on all computers. They are;

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And two folders in the profile of each user on the computer for each Firefox profile for that user.

If you remove the Firefox folder, the user profiles would not be affected.


Let's try this first; [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 I try to verify the integrity, this happens:

> Task: checkIntegrity - Unable to check database integrity > Task: invalidateCaches - The task queue was cleared by an error in another task. > Task: checkCoherence - The task queue was cleared by an error in another task. > Task: expire - The task queue was cleared by an error in another task. > Task: vacuum - The task queue was cleared by an error in another task. > Task: stats - The task queue was cleared by an error in another task. > Task: _refreshUI - The task queue was cleared by an error in another task.

I removed the files, restarted firefox and the folders magically reappear when I click 'Bladwijzers' and the best thing: my firefox doesn't 'hang' or stops working anymore! Thank you!

Sounds like the places.sqlite file was corrupt.

That was very good work. Well done. Please flag your last post as Solved Problem so others will know.

I already have chosen the suggestion that solved the problem and I can't pick two. Why do I have to pick my own, less informative, as the solution?

Sorry, I didn't know a solution was picked.

Ah, well, that's okay. I was just a little in doubt. When I got the notification e-mail I was like: I would swear I have chosen a solution.

BTW, nice support forum. Kudos. Keep up the good work. Have I mentioned how much I like using Firefox?
