> This might be a Windows issue rather than a Firefox issue I leave multiple tabs open for weeks+ on Windows (and android), I have never experienced any issue (except when windows decides to update - but firefox always restores itself without issue, or I can press ctrl+shift+t to reopen previous tab/session). There must be something specific to the other commenter's setup, whether it be specific addons or specific pages that are causing the crash.
