[Unrelated] Crashes with Friefox 38.0.1

[blancsanglier]

After auto-updating to Firefox 38.0.1 (from 37) I had lots of crashes on startup or page navigation. After troubleshooting by refreshing Firefox (which got rid of the crashes) I found that reinstalling a few addons brought the crashes back, but that disabling NoScript (2.6.9.22) gets rid of the crashes again. The crashes come back with NoScript enabled. The only other addons I have installed are uBlock and Logitech SetPoint, and they don't seem to be responsible for the crashes. All this makes me think that somehow Firefox 38.0.1 and NoScript 2.6.9.22 are not playing nicely together, at least on my computer (Windows 8.1 64).

Can you try creating a new profile and seeing if that crashes too?

38.0 or 38.0.1.

There is a Nvidia video card related crasher with 38.0 fixed in 38.0.1.

I had lots of crashes

about:crashes, the last few crash report URLs?

My last four crashes were:
https://crash-stats.mozilla.com/report/ ... 5462150516
https://crash-stats.mozilla.com/report/ ... 0d72150516
https://crash-stats.mozilla.com/report/ ... 5da2150516
https://crash-stats.mozilla.com/report/ ... 40e2150516

I do have Nvidia graphics (GTX 770), but this is definitely 38.0.1, so if they really fixed that issue, it's not the problem (and as I say, Firefox seems stable with NoScript disabled).

I did refresh Firefox, which I thought is the next best thing to trying a new profile, but that didn't solve my problems. I don't really understand what I lose if I try a new profile - maybe I can just restore from Sync.

Anyway, looking at my crashes suggests that the culprit might be something called rookscom.dll which seems to be part of Trusteer (some kind of online banking safety system). Maybe that is interacting badly with NoScript. (Though it didn't used to.) All very puzzling, if I can figure out how to disable Trusteer I might try that.

You got it - NoScript is just the messenger, the real culprit is rookscom.dll. I think it's the same problem as viewtopic.php?f=7&t=20806 .

Ok, so after disabling Trusteer and re-enabling NoScript, Firefox appears to be stable. So I now do tend to think that somehow the upgrade to 38.0.1 has brought Trusteer and NoScript into conflict, when they were fine together before. I'm not sure it's a permanent solution for me, because I may want to re-enable Trusteer for internet banking safety.

Thanks for pointing out the other thread. So I take it that there's a bug in Trusteer which gets exposed somehow by NoScript? And so I should go bother the Trusteer people

You're welcome.

Yes and yes.
If you do contact them please let us know what they say or if they fix it.

Oh, and if it really matters to you, a temporary solution could be to downgrade to Firefox 37.0.2 (if it doesn't have the same problem) until they fix it? If you don't run NoScript in Scripts Globally Allowed mode, and you're careful what you (Temporaily) Allow, NoScript could be enough protection that publicly known browser security vulnerabilities may not matter. I've run REALLY outdated Firefox versions that way with no issues, being just one release behind should be no problem as long as you're aware of the risk.

@spastorino: Your issue _is_ different (and I think could be related to NoScript but not sure), so I've split off your posts to viewtopic.php?f=7&t=20818 so that you get proper attention.

[tinchoflavour]

Same problem here. I disable Noscript and Firefox doesn't crash. Noscript version: 2.6.9.22. Firefox version: 38.0.1

[tinchoflavour]

Sorry. The solution for me was this: viewtopic.php?f=7&t=20817

[Giorgio Maone]

Everybody, could you check whether the problem persists with latest development build 2.6.9.23rc3?
It does contain a few changes in the area (HTTPChannel management) which seems to trigger the Trusteer bug, so it may have the side effect of working around it.

Good luck and let me know

Hi all, I've been having exactly the same issue with Firefox 38.0.1 & NoScript 2.6.9.22 since yesterday, and it looks like the solution was (as suggested by Giorgio in an earlier post) to uninstall Trusteer Rapport.

To confirm, these were the symptoms on my system:
- Two different Win 7 x64 computers (home PC and work laptop)
- Auto-updates for Firefox and NoScript enabled on both systems
- Work laptop performed a background update yesterday and started crashing immediately, but I hadn't noticed the update at that point.
- Crashes were intermittent and not very frequent, maybe one or two an hour. I presumed it was something like Flash plugin causing the issue as the crashed were more prevalent when loading pages with Flash embeds.
- During the last 15 mins of being at work I started to investigate cause of crashes today:
- Used the 'Refresh Firefox' button to try and fix things first. Didn't help.
- Disabled all add-ons, which helped. When add-ons enabled again, crashes occurred within 1 or 2 mins.

- Came home, booted PC, browsed around for a bit (no issues), then noticed Firefox Sync had failed to run and that there was an update for Firefox.
- Applied update, restarted Firefox, immediate crashes ensued. Tried relaunching firefox multiple times...there was just enough time to get to the Add-ons page to disable all add-ons before it crashed again (literally after clicking the 'Disable' button).
- On subsequent relaunch, no crash, able to browse happily.
- Enabled add-ons one-by-one (with re-launches in between) leaving NoScript for last. No crashes until I enabled NoScript, whereupon the crash was immediate
- Disabled all add-ons except NoScript, still got aggressive, immediate crashing.

I then came to check the support forums etc and found this page. Removed Trusteer as Giorgio suggested and now everything is working perfectly again

Would be helpful to reinstall Trusteer, then the latest #dev version of NoScript (linked above) & see if the crashes continue.

Might help rule out, or confirm, a possible link between NoScript & Trusteer.
