Sure, I can, but it would be a hassle and I'm kind of comfortable with what I have now. The first thing that hit me when I tried to get back to firefox (a couple weeks ago) was actually the time to load a page. It felt long compared to what I am use to. Sure it's anecdotic, but I opened a game called factoryidle that ran capped at 200 fps on Brave, it was only at 70-80 fps on Firefox. The adblocker I had installed was also inferior to Brave's. I guess it may be due to some extensions or I don't know, but something was wrong and I didn't want to do the effort to fix it.

It's like I want to believe, but as you say, I'm too lazy. I will try Ungoogled Chromium since you recommand it.
