Problems with bookmarks and history not working properly can be caused by a corrupted places.sqlite database file.

You can check for problems with the places.sqlite database file in the Firefox profile folder.

I am using Firefox 26.0 for mac

The way to fix issues like this is the same for all platforms.

What did you try so far in case you still have this problem?

If the places-maintenance extension didn't help then you have to delete the places.sqlite file to make Firefox to create a new file.

So deleting the places.sqlite file to make Firefox to create a new file worked. Glad I had a bookmark backup. Thanks! Al
