Windows 10: My Firefox invaded by the Matrix? (UI Glitching)

I've been staying on the stable release channel of firefox, updated to Version 71 a few days ago, and either its something I changed in the "about:config" section that didnt translate well into version 71 when I updated, or something in this release is turning itself into fractals because the devs missed something when they pushed this into the stable channel

the following attachment has both an example picture on what it sometimes does (NSFW links were edited out except one that took care of itself, thank you glitches, for once), the list of extensions I currently have installed on my firefox (all updated to their latest stable release, no dev/nightly versions installed), and the prefs.js file that contains the changes I made in "about:config", to both increase my own security, and to frankly turn off some stuff I did not want on at all (PiP mode, pocket, etc...)

Yes I have reported this on bugzilla and am waiting for a response for either a passing dev/admin/mod/whoever bothers replying, but like the last time I used it, its going to be a long while till I get a reply there

Windows Version is 1909 OS Build: 18363.476

Virus in Microsoft Edge invades Firefox

I use Firefox and Google as my browser. I have never used Microsoft Edge, but there is an icon on my tool bar, and a virus lodged itself in there that periodically invades my Firefox page when I am browsing. It locks up my computer, and puts up a screen
that says a virus has taken control of my computer and I need to click on a link that will take me to a Microsoft Engineer who will help me get rid of it. If I don't, my bank, finance, and other personal info will be stolen so I had to act fast to stop
it. Control>Alt>Delete>close Edge gets rid of it temporarily, but it is still lodged in there and comes up at random intervals. How can I remove this virus?

 

Web Matrix support is ending this year.

Can i expect any tool like WEB Matrix from MS ?.

Obviously VS Code is not replaceable with Matrix (having a lot more features like Dev Server, better UI, lot of plug in support) .
