Hi pgriffin, on the Options page, go to the "Home" panel by clicking Home in the left column.

For "Homepage and new windows" choose Custom URLs. Then you can enter addresses(es) for tab(s) you want as your home page(s).

Does that work on yours?

Version 61.0.2 of Firefox doesn't appear to have the option of selecting a custom startup page. The only options under Startup are "Restore previous session" and "Always check if Firefox is your default browser." There is nowhere to enter a URL or to select the current page as the startup page. That option was available in previous versions of Firefox.

Hi please follow the URL above your reply or go to Options then Click on Home which is where you turn off all the tiles and select a homepage you would like to use.

I'm not having a problem setting the home page. My issue is with the startup page.

Please expand on your issue with the Startup page then.

Firefox is supposed start up with your home page if you do not check the box to restore your previous session. What page are you getting instead?
