Huge fan of Firefox (and Mozilla in general, leaving aside the recent controversies) for a decade and a half. But after the great improvements in performance as part of Quantum (v57), the last 2 years or so have been a slow degradation of performance for all power users (esp. users who keep a large number of tabs open, and especially so on OSX. Firefox is almost always the single biggest memory hog on my system, and pushes the fan spinning at full speed every few hours. I wish there was more focus from Mozilla on continuously improving (or atleast keeping stable) Firefox performance, instead of these cycles of degradation, 1 great release to fix issues, and then a few years of ignoring perf again. ;(

Firefox performance is very important to Mozilla. Mozilla has a dedicated Firefox performance team and some of the team members are "tab hoarders" with (literally) thousands of tabs, so they have a personal interest in keeping Firefox performing well with many tabs. :) If you experience a performance problem, you can use the Firefox profiler to record a performance profile and share it in a Bugzilla bug report. Having a profile makes a performance bug much easier to diagnose and hopefully fix. The profiler is easy to use: it's just a toolbar button to start/stop recording. Here are the instructions for enabling it: https://profiler.firefox.com/ https://profiler.firefox.com/
