I recently bought a cheap&small office laptop with intention of taking it with me and completing assignments in public places. Problem is, it chokes up and dies when running more than eight tabs on firefox. I also tried k-meleon, it has great performance but the UI is ancient and many websites that I need dont support it.
for Firefox v93+, set
browser.tabs.unloadOnLowMemory
totrue
inabout:config
; it’s probably the same in sufficiently up-to-date Firefox-derived browsers
