When Firefox keeps freezing for no apparent reason, following the right troubleshooting steps is the surest way to fix the problem.

Clear download history If Firefox freezes when you try to download a file, clearing your download history may resolve the issue:

1. Click the Library button and select Downloads 2. Click Clear Downloads

Create new places database If your browser keeps freezing at random, Firefox’s places database may be corrupted. You can create a new database if you don’t mind losing today’s history and bookmarks. Here’s how to reset the places database when Firefox keeps freezing:

1. In the top menu bar, click Help → More Troubleshooting Information 2. Locate the Profile Folder section in the Application Basics table and click Show in Finder. Alternatively, you can locate this folder in ~/Library/Application Support/Firefox/Profiles 3. Open the gdpl1e1q.default-release folder and quit Firefox completely 4. In the profile folder, rename places.sqlite to places.sqlite.old and places.sqlite-journal to places.sqlite-journal.old if it exists 5. Reopen Firefox

Hi James,

Thanks for your thoughts here. Unfortunately, I'm unable to action any of these suggestions.

The window and top menu bar aren't staying open/visible long enough for me to click anything. They appear and then disappear almost immediately.

I would be glad for any other suggestions!

Kindly,

Deborah
