Um actually... Opera and Edge weren't always based on chromium!

Firefox with add-ons. Especially, but not only, Ublock Origin.

This is why I've stuck with firefox through thick and thin

Brave, Vivaldi, Edge and other chromium browsers are forks of the main chromium project. They can decide whether to include or exclude features from mainstream chromium.

As far as I know, Brave and Vivaldi will keep Manifest V2 extension support and said that they will not ship WEI (Web Environment Integrity).

Discord uses a modified version of electron, and it's also probably an outdated fork as well, although I am not sure about that.

Steam, in the other hand, uses CEF, which they use as a way to render it's interface and as a replacement of VGUI (a good example of this is the steam game overlay), I don't know if they will ship WEI if it ever releases in chromium as there isn't a statement from Valve yet.

If I missed something, please tell me!

Google accounts for some 80%+ of Mozilla’s revenue. Firefox struck a different kind of deal with the devil than chromium browsers, but Google is the one pulling the strings.

This feels weird to say.... I really think Microsoft should've stuck with trident / edgehtml.

Wait STEAM AND DISCORD ARE CHROMIUM?

Mozilla doesn't make it as easy to use the Firefox / Gecko engine in other projects, which doesn't help for adoption.

Firefox is kept alive by Google default search money AFAIK otherwise why don't they sue google for showing different search results page in firefox

wait, the steam browser is chromium? no way

I just wish Mozilla didn't just tread Gecko as part of Firefox, the few who tried developing on it came to the conclusion that it's not sustainable if the engines developer doesn't give a fuck about you! :/

It gets worse. All Electron applications are Chromium, too.

Firefox user since before it was called Firefox.

But... but... it's an open-source...

Edge wasn’t always chromium. It was their own engine and it was great, but too many people complained essentially that it wasn’t chromium so they switched to chromium.

Safari still uses the WebKit engine... right?

Google Chrome used to use WebKit before switching to their own weird engine that a whole bunch of other browsers now use.

Be sure to install AdNauseam on your Firefox to really go full "fuck you" to google.
