Lately, I've had a lot of performance issues with Firefox. I can pop open Task Manager at random times and see Firefox in the 2GB range (this on an 8Gb machine running Slack, Chrome and PHPStorm at the same time, so it's a little cramped for RAM at the best) and I'm running 20-30 tabs. Even chopping down to a handful still keeps you well over 2Gb. It won't seize completely the way it used to prior to multiprocess, but you get this weird situation where you get a spinner just switching tabs. For many years, I defaulted to Firefox because of an extension I loved (FireFTP) which could never make the leap to WebExtensions. I can recall developing on Firefox then patching things to make IE6 happy. But on my home machine I switched to Vivaldi entirely.
