The problem re-occurred again today when I had 10 tabs to print one after the other. The symptoms were exactly the same as before, described above, occurring after selecting the third tab and requesting it to be printed. When I closed Firefox and tried again I was only able to print one tab before the problem occurred.

But then after Firefox 3.0 was released I gave it another go - and the problem seems to have been resolved. No matter how quickly I switch to another tab and select Print, it behaves as it should. Thank goodness - Firefox is so much better than IE.

No matter what I do in I.E., e.g. select the next tab and start printing its page before the previous tab's page has finished printing, I can't break it. So it really does look like a Firefox problem. (I still use Firefox for most browsing as I much prefer it to I.E..)

</p><p>I forced the problem to occur again (by trying to print the page in the next tab before the previous page had finished printing and before the Canon print progress box had disappeared). As usual, nothing happened (i.e. it didn't print and no print was added to the Canon print queue) and when I tried to print again I got the error message box saying print function is not available. I tried printing from yet another tab I got the same error box.
</p><p>So I clicked the X to shut down Firefox, and this time, as you suggested, I waited and after half a minute or so Firefox ended, and, on re-starting it, it told me that it had crashed.
</p><p>For your point about printer drivers, I have software that monitors for driver updates, so I'm sure I do have the latest. And the problem has been occurring for months, during which time I've re-installed Windows and all software onto a completely new system drive disc; this made no difference to the problem.
</p><p>It appears that, if I don't wait for each print to finish processing completely before requesting another print, Firefox's printing routine fails in some way such that it never finishes (stuck in a loop?). Task Manager shows some activity for Firefox all the time after this has happened. So my guess is that when I try printing again the routine cannot start because it's already active. Then when I try to close Firefox, whatever has gone wrong with the routine causes the whole of Firefox to crash. Could it be that there is some incompatibility with Firefox's print routine and the Canon print driver?
</p><p>I also sometimes print from Paint Shop Pro, Microsoft Word and Publisher, Open Office Writer and Calc, Thunderbird, Foxit PDF Reader... and I've never had the slightest problem printing from these applications. It must surely be a bug in Firefox, mustn't it?
</p>Hi PeteThirdEye,
It might be saying Firefox is already running because a process is taking a while 2015-06-10T09:25:24-07:00rmcguiganhttps://support.mozilla.org/zu/questions/1066206#answer-739536<p>Hi PeteThirdEye,
It might be saying Firefox is already running because a process is taking a while to close the program completely, when you restart Firefox do you see an apology that Firefox closed improperly?
