Firefox Support Forum

Firefox automatically upgraded itself to version 41 and now the Trusteer Rapport Endpoint Protection icon is no longer shown to the right of the address bar. It is still there and working in Internet Explorer. The same situation is happening on 2 PCs, both Windows 7 64 bit.

Surely Trusteer Rapport is a widely used feature - one would have thought a new release of Firefox would have been tested to work with it.

Running Windows 7 (64-bit). Two days ago, any time I started a new tab, I would get an error box similar to the one attached and the subjects line. About 3 to 4 times per tab open. No matter if I hit okay, or cancel, no difference. Everything worked as needed. Last night, firefox Quantum was forced installed, and now nothing works any longer. No internet connection, nothing. It's pretty much a dead piece of software.

I have uninstalled it using various methods. One was to rename the folders in Program files to old and re-install. No go. Used the Control Panel - Programs and Features. No go. Followed about all instructions I could find, but the error does not go away. Reboots, safe mode, you name it. I even installed the previous copy, an no matter how often I change settings to not automatically install updates, that Quantum update will eventually force it's way in and be installed, no matter what. I think that pending update is what broke this, and now it completely non-recoverable.

It's pretty much bricked at this point, and I have had to switch to Chrome for everything, while I used both depending on what I was doing in the past. The poor working and memory hogging of the past version forced me to use Chrome more and more, and I may have to give up on what once a good and decent product, as it apparently was not tested with Windows 7 as I see a series of similar issues, and no solutions. Everybody is provided with similar instructions, but I have yet to see a working solution.

Firefox 56.0.2 fails to launch. Running on Windows 10 64 bit May be related to Norton Taskbar I installed on prior version.

I tried starting firefox 57 in safe mode and while there is some activity, the browser does not open as it normally should. I have attached a screenshot of what I see - where do I go from here. This is in safe mode.

I have tried everything, but Firefox won't open. Hasn't worked for two years, and I thought a totally clean install of Quantum may fix. Here is the windows event error: Faulting application name: firefox.exe, version: 57.0.0.6525, time stamp: 0x5a085587 Faulting module name: ntdll.dll, version: 10.0.15063.608, time stamp: 0x8274fd8b Exception code: 0xc0000005 Fault offset: 0x000000000001f8cc Faulting process id: 0x132c Faulting application start time: 0x01d360fa7c6cdfef Faulting application path: C:\Program Files\Mozilla Firefox\firefox.exe Faulting module path: C:\WINDOWS\SYSTEM32\ntdll.dll Report Id: 32cfb942-b173-4e33-8174-a1a8a7139fcc Faulting package full name: Faulting package-relative application ID:

I am so out of ideas, but am not happy with Chrome, don't want to use edge. When this all started back in spring 2016, I just loaded chrome and said screw it. Thought I'd go all in trying to fix this time. I am running a fully updated install of Windows 10, have never had ANY issues whatsoever, don't know why firefox is a problem.

Any suggestions?

I didn't realize what I was doing back when I downloaded Firefox at first, and I'm not even sure the 64-bit browser was even available back then. If I downloaded the 64-bit Firefox, would I lose all my data?
