Problems with some websites
Hi everybody! Recently I've been signing in an amazon prime account which gives me access to many service. One of them is Prime Video. I've never been able to use Prime with Firefox. It let's me navigate inside the website but when it's time to stream the movie/series/stuff that I choose, it tells me that I can't because I need to get the latest version of Firefox. Well... It's nothing special in this case, since it's just entertainment. But very recently (less than a week) I have the same problem with whatsapp web. And this is quite annoying since I use it for work and to have another browser open makes me slow down on my job. Can you tell me if there's a solution to this? My version of Mozilla Firefox is 83.0 (64 bit) and it says it's the latest. No need to update. Sorry, the pictures are in italian (I'm from Italy). Let me know if you need any help with translation. Thank you in advance!
Websites say that Firefox is outdated or incompatible even though it's the latest version https://support.mozilla.org/en-US/kb/websites-say-firefox-outdated-or-incompatible

I guess the link is too old. Went to about:config and looked for some of the strings. I found them but nowadays there's no way to right-click them and then reset.
Double-Clicking on a True/False preference will change from one to the other. Double-Clicking on preference using a value will open a small window to change its value.
