I have a tendency to switch my default browser every so often. I like playing with new toys.
I just switched from Safari to Firefox 3.5.5 and discovered I couldn’t stand
the way external links open in new tabs though I wanted new-window links such
target="_blank" to open in a new tab.
This used to work via browser.link.open_external.
But no longer. They nuked this via bug 324164. I can sort of understand it. Most people want a new tab or a new window on each new link. However, if you use spaces in OS-X or desktops in Linux, then setting this unified option to “new tab” sucks -- you have to play “hunt the window” every time you click a link in a program.
Fortunately, someone came to our rescue with a handy addon: Tabs Open Relative (Modified) by mojo-chan.
It also has the side-effect of opening new tabs just right to the current tab, like chrome does. I’ve become used to that behavior and definitely prefer it.
