I have 200 tabs open in Firefox (3 windows), 100 tabs open in Opera (1 window), 37 tabs open in Chrome (1 window) and 51 tabs open in Firefox Nightly (x64, v9; 2 windows).
Obviously my efficiency has gone to hell with all this clutter.
Could you recommend an addon for Firefox which is more efficient than having all these windows, tabs and browsers open constantly?
I am thinking maybe Speed-Dial groups, or some other group bookmark orientated "Keep for later" addon... or maybe a Bookmark addon providing keyboard-shortcuts for "bookmark to specific group" functionality.
Offline storage (i.e. for viewing on the train or on the slow-connection at home) would also be good.
