User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:55.0) Gecko/20100101 Firefox/55.0 Build ID: 20170824053622 Steps to reproduce: 1. Open a new Private Tab 2. Browse to any page 3. Right-click anywhere on page and select "Inspect element" 4. Click "Responsive Design Mode" 5. Firefox window crashes Actual results: The window becomes white and totally unresponsive - impossible to close the tab, or switch to another tab. I have to close the entire window, or kill the process. Expected results: The Responsive Design Mode should be executed in the same way as if I wouldn't use Private Tab
Hi. I can't reproduce this issue on Arch. I tried 55.0.3 and Nightly. So this may be platform specific? Have you got any addons installed? Can you reproduce the problem if you run firefox in safe mode? https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode In steps to reproduce, you say Firefox crashes. Do you get the crash reporter? If so, could you please post a crash report id? But if the browser is just hanging, you can force it browser to crash, which should generate a crash report. The instructions are here: https://developer.mozilla.org/en-US/docs/Mozilla/How_to_report_a_hung_Firefox
I could not reproduce either. I tested on FF55 and FF57 both on Windows 10.
Component: Untriaged → Developer Tools: Responsive Design Mode
Also, do you see any errors in the Browser Console when this happens?

I would really like to find the root cause of this issue, but the reporter doesn't seem to reply. This is a tricky issue, so I imagine it may a require some back and forth diagnostics to work out. Please re-open if I have made a mistake.
