Firefox 141 Release Brings Lower RAM Usage on Linux

Great, this can't happen fast enough for me. Now to be fair, I stress Firefox's memory usage by having a metric shit-ton of windows and tabs open simultaneously. But that aside, any improvements in memory usage will be greatly welcomed here.

>Some forms just break in Firefox for me. I’ve been applying to a lot of tech companies, and roughly 10% of their application forms fail in Firefox but work fine in Chrome. I can’t figure out why it’s inconsistent. Even some CAPTCHA and payment pop‑ups won’t load.

>Most browser games(I play an absolute shit ton) run WAY better on chrome than Firefox, on both macOS and Android. Not sure about Windows where I play full real games.

>Home Depot. They never test against Firefox, so most of their pages are a dumpster fire.
