Firefox had freezing issues on my laptop and my desktop in the US. After all the years of using it, I became spooked by bad programming. It would hang Firefox up and I would have to {cntrl}{alt}{del} and kill the process. Many times.

I figured it was a developmental flaw and would be fixed in future versions. I am reluctant to put it on the new machine.

Yup, latest update. Weird that it's random.

I used Firefox for about 4 years and loved it until I found Chrome. I just prefer the clean layout. Not worth it to download it just for the one website.
