Firefox was updated. I was Hacked. Now I cannot log into my email Provider. Firefox is my default browser. How do I access my email provider via firefox browser now?

Hi, I opened Firefox to continue with my work, just to get greeted with a 'start a new profile' page. All my profiles, saved data, history, add-ons and customization, were discconected/removed. Even on my phone it logged me out from my account- logging back in doesnt retrieve my history from my previous sessions on my desktop device.

I tried logging in to my account, checking if theres an 'old firefox' folder on my device or anything like that, but it did not retrieve any of my old data.

Just to clarify, I have not played around with my settings, left or deleted anything, so I really dont understand why I've just came back to nothing.

Was wondering why this happened, how do I know this won't happen in the future, and if, when possible, how can i get all my data back?

Thanks

When watching a video on a platform and the video needs to load, instead of pausing to load then play it once again, it doesn't stop, making the video audio sound so glitchy that you can't understand it

surprisingly, it works as expected on youtube

When I switched to vertical tabs in Firefox, the Hikcentral professional web client camera server page changed, part of the page appeared at the top, making it difficult to use and watch the camera images, and the image doesn't display properly. How can I fix this problem?

When I open a new tab, I have it set to the home page. When I go there, it adds the most visited sites, yes? ok. but...now when I go there, it has a bunch of sites past my pinned ones. When I dismiss one, all of them disappear except my pinned. A few minutes later, I open a new tab, and theres a bunch of new sites again, but I can only dismiss these one at a time, and they again disappear for some minutes, or a couple/few tab openings. Bug or feature? how do I fix it?
