I know most of the answers here, prefer Gecko over Chromium because Google is a monopoly, but honestly I would like to make the switch, the bad thing is that I still find the Firefox interface on Android old, I know it seems a bit silly to risk a little privacy for a comfortable and visually pleasing interface, but recently I saw that Chromium forks are even more secure than those using Gecko, that’s why I still use Cromite
I take this opportunity to say that possibly the solution to this is WebLibre, a browser based on Gecko which is exactly what I’m looking for, unfortunately still in alpha but from what I’ve seen it’s on the right track



I use Fennec and Nightly on Android, mostly because of extensions. On desktop, I’ve been using Vivaldi.
Personally I feel that XUL Gecko > Vivaldi Chromium > Current Gecko. Especially since Vivaldi’s built in tracker and ad blocker is really good and Chromium feels much smoother than current Gecko. I do hate that it’s propping up Chromium market-share, but at least I can set up Vivaldi to use their own custom user agent.
I feel that Gecko/Firefox lost so much with the switch away from XUL and to WebExtensions.
Pardon my ignorance, what’s a XUL Gecko?
The old extension platform before the switch to WebExtensions. I was just saying Firefox pre-Quantum was better than post-Quantum (after the switch to WebExtensions and away from XUL extensions).
I see. Thank you for a clarification!
