I was pretty sure manifest v3 had already happened - but when I knew it was coming, I went ahead and switched ahead of time. Came with the extra bonus that now I’m ad free on mobile too! Mobile websites are absolutely filthy with popovers and 2 sentence paragraphs with an ad between every paragraph. I’m sick of it. And unfortunately I spend so much more time browsing the web from my phone these days than my desktop - so when I swapped on pc to Firefox, it was such a relief to have browser extensions on my phone now too.
