Using F5 Key to Refresh/Reload Page in Mozilla Firefox 3.5+

I don’t know why, but I recently noticed that the F5 key no longer refreshes the page (reloads the page) when using my Mozilla Firefox web browser. I’m a web developer, so I am often refreshing/reloading pages to see what changes look like as they are completed. I don’t know when Firefox changed (maybe with the release of 3.5), but I now apparently have to press Ctrl + R in order to refresh/reload the page that I’m on.

Has anyone else encountered a problem with the F5 key not reloading the page in Mozilla Firefox? Is there a workaround or a way to map keys in Firefox?

Firefox Crashing – Mozilla Crash Reporter – Firefox had a problem and crashed.

I don’t know what is going on, but ever since I installed Firefox 3, it has been crashing occasionally. From time to time, when I shut it down, I get the Mozilla Crash Reporter window popping up. Has anyone else encountered this problem? Any suggestions? Here’s a screenshot of the Mozilla Crash Reporter that appears when Firefox Crashes

And here’s the text that I see within the Mozilla Firefox Crash Reporter window:
