PAC file causes foxy prox to crash Firefox on Linux, and freeze on Windows

Wed, 10/28/2009 - 23:20 — djcovey

I've configured foxy proxy to use our PAC file for the proxy and its causing a segfault on Linux, and in Windows XP causes Firefox to freeze.
I can provide the PAC on request, would prefer not to have it public.

‹ When trying to upload something to website, Firefox still tries to use system proxy instead of FoxyProxy rules Release notes tab opens multiple times ›

Thanks for mailing those to

Thanks for mailing those to me.

I suspect this is a race condition because I'm not able to duplicate it on Firefox 3.5.5 on Ubuntu 9.10. Can you try a test for me?

1. Copy the PAC file to your local hard drive
2. Change the URL of the PAC file in FoxyProxy to file://c:/path-to-pac/thepac.pac
3. restart firefox and post here (not https://bugzilla.redhat.com/show_bug.cgi?id=530236) if you still get the crash or freeze on Windows

If the above fixes it, then I know what to fix in FoxyProxy to prevent the race condition. If not, I'll need to re-examine the code.

Thanks,
Eric

test results

I've made the change to load pack file from local disc rather than network.  It works fine in Windows XP with Firefox 3.5.3 and foxyproxy 2.15.  I'm unable to cause firefox to freeze or crash on windows with foxyproxy.
I also tried on my Fedora Firefox (the one segfaulting) and I can confirm that still occurs using either a local .pac file, or a network resource pac file.

Thanks for the info. I'll have a beta for you to test, probably on Tuesday or Wednesday.

Crash with PAC file load notification enabled

Hi,
I noticed that firefox kept crashing while the "Notify me about proxy auto-configuration file loads" option was flagged. I casually un-flagged it and now it seems to be working great.
I'm using Fedora 12, firefox-3.5.5-1.fc12.i686, FoxyProxy 2.16.1

Cheers,
Giacomo

Many thanks for this suggestion - it fixes my crashes too (so far).
John.
P.S. Fedora 12 x86_64,  firefox-3.5.6-1.fc12.x86_64, FoxyProxy 2.16.1 FWIW

Can someone tell me where I can turn off the 'notify me about proxy auto configuration...' option is?  Since downloading FP, my Firefox crashes over and over.

Where to disable notifications.

Within each proxy configuration open the "Proxy Details" tab.  At the bottom of that screen, if you are using an "Automatic proxy configuration URL" make sure in the "Notification" section that both checkboxes are unticked.  It is these checkboxes that cause notifications to be displayed, and it is these notifications that seem to cause the crash.

crashes

Thanks.  I'll try that and see if that stops the crashing.  It's maddening.

Similar problem occurs with different version

I use FoxyProxy Standard 2.22.1 with Firefox 3.6.8 on Windows Vista.
After a FoxyProxy Update (but unfortunately I cannot determine which one) Firefox started to freeze when loading our company PAC script from web.
The freeze can be also experienced using the "Test" and "View" Buttons in the configuration. With "View" I had to kill firefox, with "Test" I could close the window receiving a message box.
The Workaround "load PAC from filesystem" I found in this thread worked.
Best regards,
Kai
PS: Thank you very much dear foxy proxy developers for providing this great tool !
