I'm having a strange problem with
Firefox 3.5.8 on
Win7 x64. If I start Firefox and close it, and then later want to start it again, the little icon in the task bar gets its highlighted background for a few seconds, then it disappears and no firefox window appears.
I have checked this against Task Manager, and found that the earlier process is still running - in the list is an entry for "Firefox *32", which usually is taking up around 200,000 K private working memory. If I kill that process, I can start firefox normally without problems.
Why doesn't this process die when I exit firefox? Is there anything I can do to "automagically" kill it, either right after exit, or right before starting a new instance, so I don't have to go into task manager every time?
I have now discovered that this does not only prevent me from opening new instances of the program when I have closed it - it also prevents some popups, if they require opening in a window and not just in a new tab. In that case, killing the current process is not an option, since I don't want to be limited to one firefox window at a time.
I experience the same problems if I try to start a second window with the first still open, by right-clicking the icon in the task bar and selecting "Mozilla Firefox".
For some reason, Firefox is preventing me from opening a new window, if there is already a firefox process running - regardless of whether I already have a window open or not.
