Note: I have updated to FF 26.0 today, and I have not confirmed whether the issue still occurs on this version. Other active extensions in FF (each of these can be active while ABP is disabled, and the closing issue does not occur): Still confirmed to occur up to Dec.20 (we enable ABP again from time to time to check if issue is gone, but it's still recurring predictably)įirefox v25.0, v25.1 (occurred during both versions on both comps) Details are as follows:īegan after updating to FF 25.0 on both machines. This is why I think it may be an issue with ABP on FF on a certain version. Each test of disabling/enabling the extension was for several days of browser usage at a time (about a week or so I think), so it's unlikely to be coincidence that the problem didn't occur when ABP was disabled. I found that whenever ABP is disabled, the issue never occurs, but when it is enabled, the issue occurs with the frequency mentioned earlier. The issue did not occur when running with all add-ons disabled, so then I started singling them out one by one. It happened intermittently, on around 1 out of 3 runs of FF, on each of two computers. I had been having an issue in which closing Firefox (by clicking the X, or hitting File->Exit) leaves the application's process "firefox.exe" open indefinately, and requires manually ending the process in Task Manager before re-opening FF. (I actually had created a new topic with this problem as I didn't see this one here, so I'll repost in this thread:) I hope this helps and you are able to reproduce and find a resolution to it as for now we have had to disable ABP like many of others we recommended it to experiencing the same problem. This issue is not present in 24 or 27 so it could be a SDK library issue that was newly introduced or conflict with changes to firefox source. We are unsure as to why this issue occurs with your addon maybe a observer or function hangs during the shutdown process or something fails to unload causing the process to hang as a result of what ever the error is it give the above annoying issue of manually having to stop the firefox or cyberfox process. We started general troubleshooting to try to narrow down the causes.įormat and reinstall of operating systems.įinally we narrowed it down to one extension they all had in common ABP

This is happening on gecko version 25/25.0.1/26 Recently on 6 different pc's we noticed that closing firefox or cyberfox, restarting for addon installs ect we kept getting firefox process is already running message and had to keep killing the task process manually now it did happen all the time but it has become more frequent.
