Diễn đàn hỗ trợ Firefox

Upon installing Firefox, it appears to run fine. However, upon closing and attempting to reopen Firefox, a small window showing "Run Firefox in Troubleshoot Mode?" will appear briefly, then close. I have already tried running it as administrator, and reinstalling several times, to no avail.

Application error: a client-side exception has occurred while loading (see the browser console for more information).

where is the browser console? how do i fix it never had an issue with until the last two days?

Fix it. Tnx, Larry Yesterday I got a full page notice that told me my access to Firefox will be shut down because my Defender detected that I had stepped in some SHXT while visiting something in Firefox. They gave me a phone number of Microsoft something to call to fix it. I did not call because it seemed like malware, I guess it wasn't because soon after Firefox would not load. I will get this when I try: Says: cannot find server v3lpea6ndyxwl4.azureedge.net , I have run Malwarebytes and Defender and rebooted. Any ideas?

I'm having major problems with Firefox and was able to use it for a long time and I love the software to death. But it has given this problem that I have run into before which the only way I was able to fix it was a full wipe of my computer to factory settings. So with this I started to troubleshoot on what I could do and reinstall was the first and send commands to refresh the dns but I found to what seems to be a startup incomplete file in the Firefox software and it seems to create itself even when deleted. It could be this which is causing problems but all I know for certain that when I click on Firefox it won't open at all or startup. With the only evidence that it responded from task manager or a popup talking about wanting to refresh Firefox for 0.1 milliseconds
