The 12.0.712.0 dev build allows you to select multiple tabs at once using Ctrl key and issuing a specific action to all selected tabs thus effectively reducing the need of 'Reload All Tabs' extension.
Thats nice, I yet to upgrade from 11 beta.
But still I prefer a button like this -
or something like this -
which does the job with a click or two !
I think thats something like "Panic button"??
U press ur customised key, and all the open tabs shut out immediately. Not only that, u can even customise which Sites u wont to open up, when the OTHER tabs are shut.
On repressing, the whole process gets reversed. Pretty useful add-on for offices!!
That was the one I posted in start of the thread, if I'm not misaken, its bit similar but it refershes all the open tabs, especially useful for people like me who go on to open something like 10-15 or more tabs at a time(many a times).
