Last time I asked Which site / problems don't work on Firefox ? >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. >Memory hog on Linux

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.

Also, here's a few settings to limit memory growth for your about:config / prefs.js: // Enable automatic tab unloading (true by default on windows & mac os) user_pref("browser.tabs.unloadOnLowMemory", true); // tab unloading enabled when free memory drops below either user_pref("browser.low_commit_space_threshold_mb", 8192); user_pref("browser.low_commit_space_threshold_percent", 30); // time in milliseconds (so 15min) to wait before kicking tabs out user_pref("browser.tabs.min_inactive_duration_before_unload", 900000); // visibility user_pref("browser.tabs.fadeOutUnloadedTabs", true); user_pref("browser.tabs.fadeOutExplicitlyUnloadedTabs", true); And here's a one-liner (courtesy of deepseek-v3) to conveniently show current free memory ratio in percent to make an informed choice about what value to put in: awk '/MemTotal:/{total=$2} /MemAvailable:/{available=$2} END{printf "%.1f%%\n", (available / total) * 100}' /proc/meminfo

  > (true by default on windows & mac os) Is that not the case on Linux?
