I-Firefox Isithangami Sokwesekwa

I ran an update on my Firefox after Flash keep causing it to hang but now the entire browser is not working. When starting in Safe Mode and normal mode nothing loads. Complete white screen. I can access the settings and options but nothing else. Can someone please help?

Hello, so I was doing something and then it started lagging. I closed Firefox and when I pressed it again it wouldn't start. It updated then it stopped working. I restarted my PC, clicked many times on Firefox logo and it wouldn't start. I got an error message in the top left corner that appeared for a milisecond. I took a video of it with my phone so I could read what was wrote there. It said "XML analysis error:entity undefined. Location:chrome://browser/content/browse Line number 53, column 1. (Sorry if it ain't the exact words, im translating because my Firefox is in french). There was also <windows id-"main-window"> under it. Don't tell me to open Firefox in safe mode, because that doesn't work either. When I hold shift, nothing happens. It doesn't ask me to go to safe mode. How do I fix this? Thanks

This is not a gripe about frequent updates, nor a case of being redirected to the "browser updated" page every time I start Firefox.

What is happening is that every time I open Firefox, I get a message from Windows asking for permission to let Firefox perform an update, then after I click "Yes" a window with a loading bar that says "Firefox is installing your updates, this may take a few moments..." or something similar to that comes up, and then the browser opens when it is done updating.

This happens literally every time I start Firefox, even if I close it and immediately start it again. This has been happening for several days now, and refreshing Firefox has not helped.

Help?

Mozilla's latest policy change, forcing FF updates and the latest messages to update are the " last straw." I don't like my computer resources being high jacked to perform upgrades but prefer to do them manually each month or so. The latest message appearing in the upper right hand corner is very annoying. I've been using FF and it's predecessor Netscape for a long time but the upgrade issue is a significant problem. This web browser will be missed. Thank you for the run.

After the last "update", every time I open Firefox, I get a box with the Firefox Software Updater. It says it's updating/installing the latest updates. This happens every time.
