Created attachment 8545854 [details] cookie.html - for reproducing the bug User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:34.0) Gecko/20100101 Firefox/34.0 Build ID: 20141127111021 Steps to reproduce: I created a test page to examine the behaviour of popsci.com articles. They store the scroll position in a cookie. So visit http://users.itk.ppke.hu/~fenta/vajon/cookie.html Scroll up and down, and watch the counter. Actual results: After 77 scroll events (bound to set cookie), no more "Confirm setting cookie" window opens. After about 130-140 scroll events, all firefox windows disappear, but the process is running. If I run it from console, it doesn't let me know what had happened. Expected results: I expected that firefox will handle infinite "Confirm setting cookie" windows or at least infinite set cookie events. I think this would be fair for people caring cookies, since websites tend to use more and more cookies.
I set the following in Preferences: Privacy -> History: Use custom settings for history -> Accept cookies from sites: yes -> Keep until: Ask me every time (This setting is good for web developers)
Component: Untriaged → Bookmarks & History
Severity: normal → critical
Keywords: hang, testcase
Summary: crash if more than 77 "Confirm setting cookie" windows are open → hangs if more than 77 "Confirm setting cookie" windows are open
Didn't we remove the "Confirm setting cookie" feature?
Severity: critical → normal
