Per the title. Firefox crashes randomly, usually (but not always) when I click a link. The issue started occurring when I had to perform a hard shutdown on my computer after a failed video driver update. The last thing I did before the first crash (after I'd rebooted my computer) was compose a JavaScript app for my website, but I used the site's built-in JavaScript app composing page, not a Firefox addon. Help!

Edit: There's something I neglected to mention. Usually, before the crash, there will be some sort of small problem, such as a quick hang or the page not loading correctly.
