hi, this got reported a couple of times and we are looking at fixing this problem in a 55.0.1 release. in the meantime it should help if you set your homepage to about:blank (while still leaving the 'Show your windows and tabs from last time' option in place).

ok - thanks - the work-round does seem to have helped. BTW where were the other reports posted?

in bug 1388628 and its duplicates it was raised.

Try to update to 55.0.1 if you haven't done this yet.

• Help -> About Firefox
• https://support.mozilla.org/en-US/kb/update-firefox-latest-version

• https://www.mozilla.org/en-US/firefox/55.0.1/releasenotes/

thanks - seems to work well!

I'm already using 55.0.2 and I still have the problem of my tabs not coming back when I close and restart Firefox. I tried the about:blank and that didn't help, either.

Hi kimberk

In case you use "Clear history when Firefox closes".

• do not clear the Browsing History

• Options/Preferences -> Privacy -> Firefox will: "Use custom settings for history": [X] "Clear history when Firefox closes" -> Settings
• https://support.mozilla.org/en-US/kb/delete-browsing-search-download-history-firefox

• clearing "Site Preferences" clears exceptions for cookies, images, pop-up windows, and software installation and exception for password and other website specific data
• clearing "Cookies" will remove all selected cookies including cookies with an "Allow" exception you may want to keep

I don't clear history. I double checked and that's how it's set. Thanks.
