back and forward buttons not working when dragging files into the window
User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:65.0) Gecko/20100101 Firefox/65.0 Steps to reproduce: opened some random page (optional: went a page backwards) Dragged some file onto it that Firefox can't open (default behavior is download): like the Firefox installer or a wave file I click abort (no download) Actual results: The forward and backward buttons aren't working anymore. Workaround for now: Press and hold the button you want to use to get the last back or forward pages and then select the one you want to go to This bug exists in Release and Nightly
I'm guessing this is a problem at the DOM level with process switching, and not sandboxing itself, because of how it affects browser history (but the DOM people can send the bug back if I'm wrong).
Component: Security: Process Sandboxing → DOM: Content Processes
Too late to fix in 64. Marking this issue as fix-optional for 65; if you land a patch in nightly and think it's low-risk for beta, please request uplift.
