Entering Firefox in Safe Mode let Ally Bank's software work. When I put it back, it is broken again. I also put all Firefox settings back to default with no luck. The big problem I have is that I don't do changes to my computer except mandatory updates for Windows 10 and when Firefox says I need to update. The ONLY thing I am aware of that changed from Feb 9, when I last logged in successfully, and today, is a Firefox update. Given that my Windows 7 computer that has a non-updated Firefox version works fine and logging into Ally Bank with an Edge browser, it would seem something is wrong in the latest update to Firefox.

I take it all back. Just trying to troubleshoot, I went ahead and updated my Windows 7 computer to Firefox 97 and it work fine. Of course there might be something in Windows 7 that lets it work but it appears Firefox 97 may not be the problem. I'll have to go check if Windows 10 downloaded something I was not aware of (I hate these forced upgrades!!).

Please keep us posted. If you think the problem is settled,

Thank you for contacting Mozilla Support.

I did find that Microsoft put 3 items on my computer yesterday. However, when I go through the system to remove the latest updates, it puts them right back on so I can't see if Ally works without them. So it appears the problem is resolved as far as Firefox is concerned but not for me to get my work done.

I started having this issue as well. I tried many, MANY things to solve it, including calling their support team, and: - clearing cookies and cache - disabling addons - reinstalling Firefox - changing Firefox version - changing Firefox profile

None of the above worked... but there was one thing that did work: Restarting Firefox in troubleshooting mode using Help -> Troubleshoot Mode, log in successfully, then restart Firefox without Troubleshoot Mode.

This got it working again, and kept it working for ~2 days. After that time, the issue started happening again on log in, and the above had to be repeated to get it working again. So, this is a workaround, not a permanent fix.

EDIT: this post has been updated to remove unnecessary steps, and clarify based on subsequent testing that this is a workaround, not a permanent fix.

Fx-Wa It could have been a corrupt file that was overwritten.

That was very good work. Well Done.

I too am not able to log into my Ally account. I cleared the cookies/cache and that didn't solve the problem. I called Ally and they aren't seeing a problem on their end. I am, however, able to log in through Chrome. Apparently, this is a problem with the latest Firefox update. PLEASE FIX THIS PROBLEM!

I do not believe this is a Firefox problem. I have another computer that I also updated with the latest Firefox (does not have Windows 10) and logging into Ally is fine. I personally also had one of those Windows 10 updates so I am assuming that is what caused the issue. I tried to delete the latest update, but it tells you to reboot, and when you do, it puts the update back on. Therefore I can't see if deleting the update solves the problem. Given Microsoft's record of releasing bad patches (several years ago they created a massive outage with companies and regular folk for several hours), I would suspect the patch is the problem.
