About:config tweaks

browser.sessionstore.enabled = false

Firefox 2 removes option to “Force link that open new window to open in new tab”. I found this to be very disappointing, since I always activate this option. Working with tabs is one of the reason I use Firefox, if some sites force me to open new window, it is just as annoying as using MSIE 6 again!!

So here is how you can set this in Firefox 2:

Open about:config and set:

browser.link.open_external -> 3
browser.link.open_newwindow -> 3
browser.link.open_newwindow.restriction -> 2
