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
