About three weeks ago Yahoo mail changed and I could not access both of my email accounts at the same time, even tho I had 2 browser windows open. GeeksToGo suggested I install a different browser system, I installed Firefox and was pleased with it for two weeks. Then, all of a sudden, accessing Yahoo email became harder and the page writing became garbled. Now even this Geeks site is garbled. So. I would like to uninstall Firefox. Can I use Revo uninstaller for that? I installed Revo a while back. Maybe I will try Chrome as a different browser.
