If you haven't been using Firefox, what are you even doing with your life?
A chrome version of Firefox is Brave.
A chrome version of Opera is Vivaldi.
A chrome version of MSIE is MS Edge.
After FF kept breaking extensions with their switch to XUL, I stopped using them.
Using Brave on desktop and Vanadium on my phone. They are more secure and private which is why I like them.
I've been using it for 20 years and switched 4 yearso ago to something else. My life is fine, thanks.
EDIT: so, the downvotes are because what, exactly?
I have been, on desktop and back when I used Android. When I kicked deGoogled Android out of my life and went to iOS where most things Just Work ™ and I could stop thinking about my phone and its bugs, I had to start using Orion because Firefox iOS sucks so much.
This news from TFA is the biggest step in the right direction; I might be able to use Firefox mobile again finally.
