Getting 404 error on my banking site
I've been using my banking site for many years on my desktop computer. Today the site comes up but when I try to log in I get a "404" error message. I tried logging in with Edge and there was no problem. I have deleted all my banking cookies on Mozilla and the result is the same. This is a major problem and I would appreciate any suggestions.
If removing and clearing nothing else works, try right-clicking the page(s) in History and selecting "Forget About This Site". The browser will record new site data and cookies when you go there again.Read this answer in context 👍 1

Can you please list out all your Firefox extensions and plug-ins? Note there are 2 kinds of Add-Ons: Extensions and Plug-Ins, and it will be helpful if you please list both.
Maybe if everybody who has the problem lists their Add-Ons we can see which Add-On they have in common and then you all can try disabling it and see what happens.
If nobody has any Add-Ons and yet it still works in Safe Mode and not in normal mode then there may be something in your profile that is somehow interfering with the operation of the website. This is most particularly the case if "forget this site" works for a few hours and then stops working.
Nevertheless, if you're running any Add-Ons then it would be helpful to know which ones they are.
I just disabled "DuckDuckGo" and "Amazon Assistant" and was able to log in to my banking account, with no reboot or Safe mode. I've had "Duck" for ages and didn't even know I had the AA.
I hope it keeps working! Thank you DBBEN!
You're welcome pdic,
We are glad to be of help. :-)
I had the same 404 error after I logged into my BMO account. I fixed it by doing the following: 1) click the firefox extension icon "DuckDuckGo Privacy Essential" 2) then click the gear icon 3) then click "settings" 4) then click "Add unprotected site" 5) then add bmo.com
@tom.pm.ma - I tried that, but then was back to the dreaded 404, so I have permanantly disabled it and I'm fine with that solution. Thank you anyway. For anyone else having this problem, this is what solved mine, thanks to the forum here. Without the assistance I never would have guessed what the glitch was.
Reinstalling FF likely wont resolve the issue with that one site. Try using FF in safe mode, by going to the Menu Bar > Help > Troubleshoot Next run windows in clean mode (temporarily) by disabling all the apps that are starting with the desktop. You can do this by Task Manager > Start Up Tab Next reboot and retry that site or log in. btw: when i visit the url, i get a an okay webpage/homepage. But i think your issue may be occurring at/after login?
Today I have this same problem with Firefox and BMO login. However, when I started Firefox in safemode it did nothing to fix things. I only have 3 extras on Firefox and they are all themes, so I didn't think it would work. But when I disabled everything in Task Manager and restarted my computer, I am able to login into BMO. I hardly have anything set on for startup so I'm going to go and see what it could be that's caused this online trouble. No doubt it's something silly. I think it's odd that it's only on one site. When I called the bank, I was told to clear my cache and that would fix it which, of course, it didn't. I just wanted to thank you for the information.
Thanks for your post. Please let us know what you find out.
If the problem goes away with the computer in Safe Mode, the problem is with one of the other programs on the system.
As a test, disable your protection programs.
