For Firefox I'm on 115.0. What's interesting is my Edge Version of 114.0.1823.67 is working.
I cloned my windows 10 boot drive to another SSD before I installed 11 (I did a clean install). I'm with you though, that reinstalling everything is a paint. I just did it with windows 10 not too long ago (about a month), as I was chasing some bluescreen issues (didn't fix it). I'm mostly fine with windows 11, I'm just not a huge fan of the new Mac like task bar now. I'm a vertical task bar and individual icons (with text) for each instance of an application like file explorer, but I guess it's not the end of the world
