I use firefox as my daily for a few years now, I switched for panorama view, and almost switched back to chrome when the extension was broken, but stuck it out until it was fixed. Quantum improved it, but I still have lots of issues with Firefox on Linux. To name a few: (For reference I'm running Firefox 67 on NixOS, xmonad, no DE, 7700K, 64GB RAM, RTX2070, only extensions I use are uBlock Origin, Panorama View, but I've run into all the problems below in safe mode also) * Still slower than Chrome if you use lots of tabs and windows (generally 100+ on 3 windows depending on current jobs). It's much faster than it used to be but I can't deny when I have to switch back to Chrome for some things, I'm surprised at the (slight) speed difference. * Visual glitches with lots of tabs the tab bar will occasionally spasm, sometimes all the text will disappear etc. * Sometimes a window will just stop working. All the tabs are still there, but they all show blank white pages, new tabs are also blank. Different windows will work and a new window will work. Restarting firefox, the same window will be all blank pages. The only solution I've found is open a new window and copy the tabs you want to save one by one to the new working window. * Bunch of websites just don't work in Firefox. In particular several of my governments payment portals don't work in Firefox on Linux but work fine in Chrome. * Sometimes I get crackling audio from Firefox that can only be fixed by restarting pulse, never had it happen in Chrome. * Some streaming websites choke firefox out, for example ufc.tv PPVs are sometimes entirely unwatchable in FF, the audio and video fall out of sync after a few minutes, sometimes it can makes other tabs sluggish. Never have a problem with Chrome, will usually just open a chrome window to watch live streams. I chalk most of these up to Linux weirdness, but I do quite often find myself annoyed at FF considering its running on a moderately well specced machine, and its literally the only app I run regularly that gives me heartache. That being said I've stuck with FF over Chrome and still prefer it for various reasons and recommend people try it. I just disagree with the idea I see floating around that there's nothing wrong with FF at all and its just as fast and stable as Chrome. It's not been my experience.
