Firefox is a fully open source browser. Whether or not it fails and goes down doesn’t really matter, as its source code is out there for anyone to use, and build a browser off of it.
Stopped using that garbage browser a couple of weeks ago. Hardened Firefox ftw. Just using stock Firefox isn’t enough if you’re concerned about your privacy on the internet btw. If all you’re looking for is an ad free experience tho, then stock Firefox should be enough.
Oh, ok.
