I've been using Firefox since 1.5, I've accepted memory leaks as a fact of life. For comparison, I currently have two browser windows open and zero tabs. One is this comment box, the other is a GitHub page. Firefox is using a grand total of 3GB RAM, about 700MB of which is for the WebExtensions process so figure about 2.3GB for a grand total of two pages. This is actually an improvement on the way things used to be, but if I quit the browser now (as I probably will soon regardless), these same two pages would take up only about 200MB, which is still a lot for what it is displaying and running, and the WebExtensions process would reset to about 200-300MB. I have Waterfox running in the background too, basically Firefox 56, which I use for a single website with exactly one extension taking up over a gig by itself with a single page open. I'm not complaining, again, it's a fact of life that I've accepted and it doesn't hurt me any, but if I changed my habits I have doubts about how much I would actually use Firefox. Maybe I still would after considering my other options, but the web isn't as interesting as it used to be and I have other means of getting what I want off it now so I don't really require a web browser I can throw a million tabs at since tabs themselves are pretty harmful. That said, if there are browsers that do a better job nowadays, and I stopped looking a long time ago, I'm not convinced they would do much better than Firefox currently does.
