How can stop Firefox from re-opening windows after a crash?
Hi, I have the problem that Firefox restarts after a crash, re-opening exactly the same windows that were open at the time of the crash, which most of the time reproduces the crash.
I want Firefox to restart with an empty window, like it is configured.
I have read a support entry that hints setting browser.sessionstore.resume_from_crash to false, which does NOT to the job (anymore).
Chosen solution
Check that browser.startup.page is 1, browser.sessionstore.resume_from_crash is false and browser.sessionstore.max_resumed_crashes is 0 in about:config.
Does it still happen in a new profile (without signing into sync account)? Alternatively you can refresh your existing profile.

Add the following line to a file named user.js in your profile folder :
user_pref("browser.sessionstore.resume_session_once", false);

There was no such file, but I added one. But it didn't change anything.
You can set this pref to 0 (zero) on the about:config page to always show the Session Restore (about:sessionrestore) page in case of a crash or when you force a shutdown.
- browser.sessionstore.max_resumed_crashes = 0 (-1:never ask; 0:always ask)
user_pref("browser.sessionstore.max_resumed_crashes", 0);
