If you’re like me, you set up your Firefox to restore tabs from your previous session. (It has this option in-built, but I prefer to also use the Session Manager add-on.) If you’re also like me, you tend to keep a large number of tabs going. Firefox doesn’t handle this very well, especially at startup. Things can be especially ugly if you’re on any kind of compromised connection like free wifi.
Solution: get the add-on called Restore Control. It allows you to disable the auto-load of tabs on startup. This is pretty genius because it makes Firefox restart and respond wicked quickly in the aforementioned circumstances. Be sure to check out the settings – the one tweak I required was for the width of unloaded tabs: changed it to No different than loaded tabs. This let it play nice with my Tabkit sidebar tab list. I also trimmed the space following the * in the ‘prepend unloaded tabs with’ option.
Edit: my current preferred Load Tabs Progressively
