Para abrir una ventana nueva, debe cerrar antes el proceso Firefox, o reiniciar su sistema" (Firefox is still running, but is not responding. To open a new window, you must first close the existing process, or restart your system.) If I use "Desktops" (http://technet.microsoft.com/en-us/sysinternals/cc817881.aspx) I get that error every time that I try to open Firefox in 2 or more virtual desktops. Reproducible: Always Steps to Reproduce: 1. Install Desktops (http://technet.microsoft.com/en-us/sysinternals/cc817881.aspx) 2. Activate at least 2 virtual desktops 3. Open Firefox in 2 or more virtual desktops simultaneously. Actual Results: I get the error I told Expected Results: Open Firefox
The problem lies with the fact that Sysinternals Desktops is preventing Firefox from detecting existing instances of itself. This causes Firefox to spawn a new process instead of reusing the existing one. The Firefox profile can only be used by one Firefox process at a time, so when a new Firefox process is spawned instead of the old one being reused, you have two processes trying to use the same profile, which is not allowed. One solution is to find a different desktop virtualization app that doesn't hide previous instances. You might want to give Microsoft's virtual desktop powertoy a try, but I don't know if that works on Vista. The other options is to run subsequent copies of Firefox with a different profile. The best, long-term option is to contact the Sysinternals team and let them know that their method of hiding previous instances can cause problems where multiple instances try to access an unsharable resource.
Summary: firefox doesn't open with virtul desktops → Firefox doesn't open with Sysinternals Desktops
All right... but that problem appears too some times (apparently in a random way) when I close Firefox (without virtual desktops) and the process doesn't finish correctly (these times I must kill it from task manager)
