Disappointment mostly. FF went from de facto browser to "my employer isn't even obliged to support it for clients because market penetration is below 5%". Like, containers are nice feature.... and I ran out of things to praise them for. Quantum finally caught on speed but broke stuff I used, and limited plugins so now I can't have vertical tab bar normally, existing tab bar addons have to shove themselves into sidebar. ...which means every time I Ctrl-H it gets replaced with History! and disappears completely when I enable it again! Wasn't a problem before but someone decided "plugin replacing everything you see on site is fine, but modyfing browser window? BIG NONO". I even had to dig in some files to hide the actual tabs because of course plugin can't be possibly allowed to do that. They had also few PR blunders like auto-installing some addon for promotion some time ago, or the fact they bundled pocket with it. I mean it's a nice service that I used before anyway but people complained Mozilla decided to essentially force-install a plugin in it. While before they were leader, now they are catching up, all while getting involved in some random stuff instead of making better browser. And the fact marketshare is low also means some sites just subtly break from time to time.
