It's honestly a pity. Firefox is it perfect but the Internet is becoming worse because of chrome. Google is able to fast track any non standard Web tech and the hordes follow. Soon after, that become the standard. I don't want to cheer for a broken browser, but only Safari is able to stop this madness now. Also, Firefox on the Desktop is really good and still let's you do so much more than chrome clones. But it suffe…
Chrome is already the standard. Firefox usually works, but more and more often nowadays I encounter a glitchy or poorly performing page, which I switch to Chrome to use properly. I use Firefox to not be part of the Chrome monopoly, not because it's actually a fundamentally better browser.
For me there is - in addition to not wanting to support Chrome - still a few things that Firefox does better.
As for websites that only support Chrome I consider them broken which means I don't use them or if I have to I try to notify the operator.
