Call me fickle I guess. I was on FF again tonight, I typed a song review on on a music site and it would not post in the thread. It just sat there timing itself out. I copied my post, closed the site and went back in, my post was gone, I pasted it back in, same thing happened. It would not post my reply. I opened the same site in Chrome, pasted it and it went right through to the thread. I had a similar error in Facebook on FF. Maybe it has something to do with using Ublock in FF. I have no idea, don't really feel like tinkering with it right now.
I did download and try out Vivaldi, I am posting this from Vivaldi, it is just as fast and snappy as FF, it uses less ram and has a built-in ad blocker, which seems to work pretty darn well, and I can add Chrome store extensions. I also found this article, it looks like Vivaldi may be going to do everything they can to not use or support MV3. Vivaldi seems to be ok but I don't know much else about it yet, time will tell. I don't think I will try Brave, I just don't care for how it works.
Other browser makers don't seem to be on board with Google's decision to neuter its extensions API, and essentially, ad blockers.

I really don't know how much good this is doing me anyway. I have an Android phone, I use Waze, I have a Chromecast on my tv and a gmail email and am signed in on Youtube. Google probably knows what I ate for breakfast this morning and can track me no matter what browser I use. I just want to get the full benefit of extensions the way they are intended. I don't like Google monkeying around with extensions I choose for my own browser.
