Firefox crashes on startup immediately (due to re-opening a session) - how can I force a restart without session restore?

One of my FireFox session crashed (I think the page was trying to print something), but now each time I want to restart the browser, this session is immediately restored, which immediately crashes Firefox.

I don't have any chance to interact with its UI at all prior the (re)crash.

How can I force a "clean" firefox browser start in this case?

Ah, found a solution. Right-click to launch "private session". Then open "new window" (which restored the session, but had the new window active, hence not immediately encountering the "send to printer" situation which caused the crash). Then "close all other tabs."

Still, I would have preferred a right-click option "Start without restoring a session"...

You can set browser.sessionstore.max_resumed_crashes = 0 on the about:config page to make Firefox always show the about:sessionrestore page when you restart after a crash.

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

I like your suggestion. I've filed https://bugzilla.mozilla.org/show_bug.cgi?id=1669438 to have the Firefox developers consider it. If you're interested you can create an account on that issue tracking site and CC yourself on it to monitor the response.
