Firefox Problem - White Screen of Death?

This never used to happen before.:cry

When I create a new tab and load a website onto it, whenever I switch to the first tab, all the data is gone, and it's just like a white screen of death. I need to close and reload the tab, as refreshing doesn't work.

 

Would uninstalling and reinstalling Firefox be too much of a hassle? Do you use a lot of Firefox add-ons that would need to be reinstalled? And, you'd want to export/backup your Bookmarks, I presume.

 

Which version of FireFox you running?

 

Uninstalling right now... I might switch to Google Chrome - so much faster
