Diễn đàn hỗ trợ Firefox

I like using Fire Fox (FF), but I am constantly met with resistance from different organizations which try to tell me to use MS Edge, or Google Chrome. It seems like FF is a problem for them. Now, after successfully using Fire Fox for decades, I can no longer log in to my bank account when using FF. I can use any other browser, but not Fire Fox. I've spoken to the bank, and they point the finger at FF (of course), but this time (unfortunately) I have to agree with the bank. What did FF do that now makes it impossible for me to access certain web pages, or certain features, like "logging in" to accounts?

Can you please un-F whatever you F'd up? Or, please explain to me why I can do everything the exact same way I've always done things when like using Brave, Chrome, Edge, Chrome Cast, and TOR, but can no longer do them when using FF

This problem only occurs in my Hotmail email account at outlook.live.com using Firefox in the last few weeks.

I typed exactly the same including spaces in both Chrome and Firefox. First 2 lines typed in Chrome, saved the draft, last 2 lines typed in Firefox but in Firefox the nonsense occurs. Amazingly the 2 lines typed using Chrome still display well in Firefox. Firefox adds the extra number in the fractions in the space I had typed! How can I get Firefox to work well at outlook.live.com?

This has only happened in the last few weeks, during all those updates. Am on 138.0.4 Are any of these updates buggy?

I recently downloaded Firefox and would like to use it as my primary web browser (M1 14" Macbook Pro). But my Google calendar web site is not showing any colors, making it hard to use. On my other browsers (Brave, Safari, Edge) it works fine . See screen shots below from Firefox, Safari, Brave. I have tried re-booting Firefox, the computer, reverting the Firefox theme back to basics etc., and searching on line for a solution, but I can't find anything. So far all other websites are working OK, except for 1 other that has partially the same problem. If it can't be fixed I'll stop using Firefox, which I otherwise like.

Thanks for any help.

I can not get Youtube to load on desktop Firefox. It works fine on the mobile website, app, and Chrome. I've tried clearing cookies and site data, removing extensions, resetting Firefox, and disabling hardware acceleration, and so far nothing has worked. Has this been happening to anyone else ?
