Firefox recently upgraded on my desktop. I ONLY use Firefox - do not want Google, Edge, Etc. I can get into all of my on-line accounts with the exception of my Bank Account. I do not get a message about browser - but if I click SIGN-IN, it just sits there. I called my Bank...told me I have to use Google, Chrome or Edge - DO NOT WANT TO USE ANY OF THOSE. I had no issue signing in until it upgraded. PLEASE tell me how to fix this - I have cleared my Cache and History, etc. Nothing works. Please HELP!!! Do not want to use another browser to access this account - do not feel safe with any of them - why I use Firefox. Thank you.
Did your try in Private mode?
No I didn't, but I figured out that I have to turn off the Ad Blocker in Firefox in order to open my banking site. Makes no sense because it worked before with Ad Blocker on.....Don't like using websites (even my banking site) with Ad Blocker off, but only way to get into it from Firefox.
Depending on which ad blocker you use, you may be able to whitelist that website.
