However, my biggest gripe about Safari has to be the developer tools. They're noticeably slower, clunkier, and the network tab is unpredictable at times. I think it's getting better, but I defer to Firefox to do development.
if you have a retina display, this "even" is sort of a joke, because ff is so CPU-heavy (and often slow) that it's unusable for me https://bugzilla.mozilla.org/show_bug.cgi?id=1404042
But it is true that for some users Firefox on retina is barely usable. It is a confirmed bug.
Am I using it wrong in Safari?
Because to me the Chrome integration with 1Password X extension is by far the easiest, you get the dropdown right there in the field. In Safari, I have to click the 1Password extension button next to the address field and then select Autofill.
The one thing about 1Password X is it doesn't integrate with the installed 1Password app on your system, which means no TouchID, for one.
TBH the ability to use uBlock Origin was my only killer requirement, but Container tabs are a leap in web security. I hope that idea gets stolen and becomes a norm in browsers. (Or First Party Isolation in general).
