I don't get why it's doing this, but it has for the past few weeks.

After a random period of time of browsing the internet in Firefox (anywhere from like a few minutes to a half and hour usually), it just... stops loading pages. I'll click a link or type in a URL, but it will just sit there and say it's loading the page. I've waited up to 5 minutes to see if it begins to work, but nothing happens. I have no idea why it does this, but I do know it has nothing to do with my internet, as all my other apps work fine when Firefox stops working. I end up having to restart it whenever this happens, and it's really becoming annoying.

Any ideas?

The 'Other Causes' section may have what you need.

Nothing on that page, or that I've looked for has worked. I've tried reinstalling, removing all my add-ons and plug-ins, do the standard diagnostic thing, even using a different version of FF.

Maybe Firefox just hates me.
