For a couple of months now, my favorite browser, Firefox, has been locking up on me. It started this year right after an update. It suddenly locks up! Completely! Sometimes I cannot get it to close. I have had to shut down my pc to get rid of a locked up Firefox browser. These days I only need to right click the Firefox tab on the task bar and click "Close Window". That has been a big help. So, I give up on Firefox and made Chrome the default browser. Then behind the scenes, someone installs a patch to the main server and fixes the problem. I check it often and when I see that you fixed it, I set it back to default browser for about 2 or 3 weeks and then Firefox locks up again. I shut it down and switch to the Chrome browser again. Back and forth I go. It locks up. I switch to Chrome. You finally fix it yet again. I try it after a few days and discover that you fixed it and make it default browser again. And here I am again! I cleared the lock up by right clicking on the taskbar Firefox tab. Now I get a dialog box that has an option to shut down Firefox. Then I see a time bar move across the dialog box and close. Nice touch! Now I switched to the Chrome Browser again and I am waiting for you to fix your Firefox browser for the 5th or 6th time this year. Let me give you some advice. Burn it to the ground and start over. What you are doing does not help!
