User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:38.0) Gecko/20100101 Firefox/38.0 Build ID: 20150525141253 Steps to reproduce: With no Firefox task currently running, from Windows Explorer select an HTML file and hit Enter. Actual results: After scrolling the web page, Firefox becomes "unresponsive" which is the word Windows puts in the window title bar when it then makes the window inaccessible to further use. I am able to kill FF from the Task Manager, which appears to be the only way out. When it relaunches, it tries to resume the same session. I quickly close all the windows before scrolling any of them in order to avoid a recurrence of the problem. Expected results: It shouldn't have locked up, obviously. If I launch FF from the Start Menu so that a firefox.exe entry already exists in Task Manager, even if my only open FF window is just the Library window, then I can hit Enter on the HTML file in Windows Explorer and the problem does not occur.
This bug is intermittent. I have encountered it a number of times over the past 3 or 4 weeks. But I've tried several times just now to reproduce it & I have to admit I was unable to recreate it. But honest, it was happening. I didn't imagine it. It was happening practically every time. Now it's fine. Go figure. Maybe FF figured out I was tattling on him & now he's behaving. I don't know . . .
please post a log from about:support It's possible some of your add-ons is causing this strange behavior, maybe you could try in a clean profile? https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles And if that helps you might try resetting your profile: https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings

I swear this product is self-aware. Since I posted this report I have been utterly unable to cause the problem again. And I've tried maybe 15-20 times. To my knowledge I have done nothing to alter my system. I promise I'll post again if it ever happens again but for now, I think maybe I'll just tuck my tail between my legs and slink back into my burrow.
Besides that, I think you should update your ATI Radeon HD 3400 drivers to the latest version, 13.9 (15/10/2013): http://www2.ati.com/drivers/legacy/13-9-legacy_vista_win7_64_dd_ccc_whql.exe It could fix some perf issues.
Thanks for that. I suppose I should have done that on my own a long time ago. However, this problem seems to have gone away the moment I reported it. And I am not suffering any performance issues. Nonetheless, I have downloaded & installed the newest drivers for my video adapter. Which aren't all that new, are they? I'm not sure it's made any difference. Then again, I haven't rebooted yet. The installer did not tell me I had to, which rather surprises me. But I will make a point of rebooting later, when it's more convenient for me. Assume no news is good news, which is to say, if I remain silent here from this point forward, it means everything is fine. Unless, of course, somebody posts something that requires some action on my part. I do note that, buried in the new software I seem to have acquired with this new driver, there is something that appears to allow me to define multiple desktops. That sounds like a fun toy I may play around with. And anything more about that is so far off this topic I won't mention it again.
It sounds like this has gone away ("works for me"). If you figure out steps to make this reproduce reliably and/or have more clues about something Firefox is doing that we need to address, please feel free to reopen this report.
