Please explain the problem in detail. What happens? What is the exact error messages?

more options

The error message which keeps repeating is "The User Name or password is incorrect try again" which keeps repeating each time I try to sign in. In any other browser I am allowed access immediately with same user name and password.

Many site issues can be caused by corrupt cookies or cache.

Warning ! ! This will log you out of sites you're logged in to. You may also lose any settings for that website.

If there is still a problem, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

Tried all this before contacting support. Tried again did not help.

Are you using any password add-ons or programs?

more options

NO. I have also contacted Fidelity and they cannot find anything wrong on their end. As I have stated their is no problem in Chrome, Explorer of Edge. I am granted immediate entrance with same user ID and password. I even got a new password from Fidelity -- it worked once but when I tried again I was not allowed to enter Fidelity website.

I am NOT having trouble loading the Fidelity website. I am having trouble with either my user name or password being accepted. When I try to sign in on Chrome, Explorer or Edge there is no problem and I am using the exact same user name and password. I have tried everything to get this to work on Firefox which is why I am asking your for help. I can always use another browser for Fidelity but would rather use Firefox for everything. Fidelity is the only website that I cannot enter with my user name and password and I have many other websites that use passwords with no problem. I have looked into all Firefox troubleshooting and nothing works. I have been working on computer for 30 years and am not a beginner. If you cannot help me thank you any way I will just have to work around the problem. I thought perhaps other people were having the same trouble and a solution might help them too. Which is the reason for my contact with your support.

I called for more help. You did try Safe mode, yes? Did you check out the links I posted?

more options

I have tried safe mode and have tried all the links you have sent and also tried search suggestions by other people on the internet. I have tried disabling just ad blocker and ghostery which have given trouble in the past. Nothing has helped. The only help I found was when I was able to use my three other browsers with no problem. This leads me to believe that there is either a problem on Fidelity's end with Firefox or else there is some setting in Firefox that I am unable to find to help. I do not want to try to refresh Firefox which might work because I might lose a lot of stuff in settings. I already lost some stuff when trying different fixes.
