Manifest V2/V3 is a reason to still use Firefox.
There are still a lot of differences between the two browsers and a monoculture is still bad.
How ever I see the pull towards Chromium.
Good point Manifest V3 is scary, but there are chromium forks out keeping it at bay, question is if thats a long terms solution or just a bandaid?
without PWA and a terrible service worker support, firefox holds the web behind.
Users don't care if their favourite websites are PWAs.
Not having PWA & Webworker support isn't a win.
I use PWAs myself.
users don’t care about firefox anymore either
Well, they would be holding back the web, if they had significant marketshare.
Personally at my job we dropped Firefox support. I imagine we're not the only ones to do so.
