This problem seems to be linked to version 62.0.

I rolled back to version 61.0.2 and the problem is not there.

I set Firefox so that it doesn't update; I'll wait until the devs fix the problem in the future versions.

I wish to be warned when this happens.

Thank you.

Regards.

Hi, that is not how it happens. Yes it is a bug and you can follow what is going on. Do Not make comments in bugzilla, it is not a forum or a place to leave comments of any nature. Thanks.

I would not turn off updates as then you miss security updates for issues like https://www.theinquirer.net/inquirer/news/3023893/opera-mozilla-vivaldi-and-more-rush-to-patch-spectre-and-meltdown-security-holes

hi, does it make a difference if you enter about:config into the firefox address bar (confirm the info message in case it shows up), search for the preference named browser.startup.blankWindow & double-click it and change its value to false?

Hi, The latest updates fixed the problem, I can now return to a more normal use of Firefox. Thank you guys! Regards.
