[SOLVED] "Firefox is already running" on Dual Monitors

[choogi]

I actually have 3 monitors--two of them are in TwinView and I have a third set up as a separate X server that I use just for email. I just recently reinstalled Gentoo.

Before the reinstall, I could have Thunderbird on my third monitor (separate x server), click a link in an email, and the link would open in the firefox window on my other monitors. Likewise I could click an email link on my main monitors and a "Compose to" window would open on my Thunderbird monitor.

But now, whenever I click on a link in my email, I get a "Close Firefox" window that says:

As a workaround, i use to have 2 profiles and launch firefox with something like:
DISPLAY=:0.0 firefox -P MyFirstProfile
DISPLAY=:0.1 firefox -P MySecondProfile

That way, it doesnìt complain anymore, but you'll have to sync profiles if you need it.
Maybe you can fake them by a simple symbolic link, but i've never tried.
Can't help you with thunderbird.

Okay finally figured it out.

I just had to got to System->Preferences->Preferred Applications and change the command land launcher to "firefox" instead what was there before and the problem was fixed. Now when I click on a link in thunderbird it automatically opens in a firefox window on my other window

I did the same with the thunderbird launcher and that fixed itself too
