Форум спільноти Firefox

I often hit ^T (control-T) in firefox without meaning to, because I use that chord in other applications a lot. In firefox it opens a new tab, which is almost never what I want. I'd like to suppress that keyboard shortcut. I tried doing it using vimium (unmap <c-t>) but that has no effect.

Thank you, Silvio

Due mostly to upgrades in the app software, it's necessary to restart Firefox on occasion. Also, it's necessary due to OS upgrades. While the Restore Previous Session is a wonderful feature, it arbitrarily (and properly, by default) forgets all of the Private Tabs. But, there are times when I'd like to save some or all of the Private Tabs I've got open. A 'settable' feature to 'Remember Private Tabs during Restart' would be a tremendous asset at times.
