Hello there,

Clearing your browsers cookies and cache can help remove excess data that could be causing Firefox to crash.

You can try and clear the cache/cookies by doing the following:

1. Click the menu button and choose “History” 2. Then click “Clear Recent History” 3. Clear everything and tick all the boxes before clicking on “Clear Now”

Finally, relaunch your browser and see if the issue still persists.

Hope this helps!

If you have submitted crash reports then please post the IDs of one or more recent crash reports that start with "bp-".

• bp-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
