I lost all my tabs recently & wanted to restore them. The advice via Help topic was to click the 3 horizontal lines, click history & then click "restore previous session" However I do not have that selection. I have the other shown but not restore previous session. I do have the latest version of FF & am on chrome. I was able to restore my tabs one at a time, but in the future I would like the ability to easily restore the whole session. Thanks for any suggestions.
