With all these posters complaining, am I the only one who is totally satisfied with Firefox? I never had many issues using firefox. I did use Chrome briefly, but came back to firefox. If it matters, I mostly use firefox on Debian Linux and am also not a web developer.
Another satisfied user, but it comes with the caveat that my habits let me use it. Firefox really knows how to make memory leak and if I weren’t the type to aggressively close windows/tabs I don’t need and not keep the browser going 24/7 I would probably end up switching to Safari as my default.
In my experience Firefox handles a large amount of tabs very well, while Chrome tends to eat a lot more RAM in the same situation (while doing its best to hide that fact).
On the other hand there are some websites that will easily demand a gigabyte of RAM on their own, or that use excessive amounts of CPU time. Chrome handles those cases much better than Firefox. But those are outliers, and if I have to visit them I just open them in Chrome.
