While using Firefox today, I had a malware popup (for the curious, this one: https://support.mozilla.org/en-US/questions/1030444#answer-651838) on one of my tabs. The only way to kill the popup was to kill the Firefox process. But now if I try to reopen Firefox and restore my previous session, the tab with the malware is active and unkillable. I have two windows each with multiple tabs I had as references - tabs that are buried weeks down in my history at the moment. Once upon a time, if Firefox crashed (and/or was killed from task manager's process tab), you'd get the "this is embarassing" version of session restore and that would allow you to not load the offending tab, preserving everything else. Whatever happened to that feature? Are there any plans or ways to bring it back? In situations like this, it would be supremely useful.
