Created attachment 8889145 [details] The scam which crash Firefox User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:56.0) Gecko/20100101 Firefox/56.0 Build ID: 20170722112649 Steps to reproduce: I browsed a website (adf.ly), and an ad redirected me to this link : WARNING, DANGEROUS LINK : www.support.microsoft4141afrmsf0125.com.s3-website.eu-central-1.amazonaws.com This is a scam for Windows user, it's asking an user password. Actual results: I wasn't able to close the scam tab, even with the Windows' task manager. The only way to close the tab was to kill the main Firefox process. This bug occurs with Firefox 54 and 56 on Windows 10, and with Firefox 56 on Ubuntu 16.04. Expected results: I should have close the scam tab directly, and without the task manager, or with the task manager but without kill all Firefox process.
The website is now offline, there is a 404 error...
(In reply to filman230 from comment #1) > The website is now offline, there is a 404 error... Yeah, without the resource that caused this, there isn't much to go on. This and any other malicious sites can always be reported to Google's Safe Browsing service, which protects Firefox users as well. https://safebrowsing.google.com/safebrowsing/report_badware/ Other than that, with no web page, stack trace, etc. we have to close this bug for now. If you get more information, please update.
