A childishly simplistic one. I grabbed that number from Wikipedia. I find Firefox so much better than chrome or edge, I can’t believe some metric puts some order of magnitude around 3%. Triple it to 9%, and if still wish for better.
There’s only 3-4 browser platforms chromium, safari, and Firefox which might be better said as gecko and web-kit. Ladybird and Orion are trying to enter this market with something new.
*this information is probably close to right but I didn’t double check it first.
Chrome and edge are basically the same now.
