People make fun of Chrome being a RAM hog but I'm having more issues with FF than I ever did with Chrome. For some reason on reddit specifically FF will randomly freeze for a few seconds, my cursor will stop rendering on top of it (like it's going behind the window) and it won't accept inputs. If I keep typing through it it all appears in the window after it unfreezes. Also FF will regularly take multiple gigs for random tabs like Youtube if I leave them open.
Tldr it might be more of a firefox problem than a framework problem.
I would hazard a guess that it’s more of a “devs only test against Chromium” problem than it is a Firefox problem. It’s a problem seen under WebKit-based browsers at times, too. Gecko and WebKit often behave differently and have different performance characteristics than Chromium/Blink does, but that’s often not accounted for at all. The extent of QA on non-Chromium browsers too often stops at “it technically runs”.
That's also probably part of the story but ultimately as an end user the fact is Firefox is a bad experience I'm suffering through only to not use Chrome. I can't force websites to patch whatever memory leak is causing Youtube tabs on FF to eat 5 GB of ram for example.
I have a ThinkPad T480s with Ubuntu and Firefox. Works like a dream except every now and again the whole thing locks up (have to power cycle). Happens with AWS Console and LinkedIn. Maybe it's doing me a favour.
