This article describes the steps to set two tabs as your home page: How to set the home page. Does that procedure work? If not, you could try manually copying and pasting this into the dialog:

http://xfinity.comcast.net/|https://mail.yahoo.com/

Regarding cookies, I noticed in your More System Details that you are not accepting "third party" cookies. You might try switching that to allowing those in case it is necessary to get Comcast's site to work.

That can be adjusted on the Privacy tab of the Options dialog, when you have "Use custom settings for history" set. More info: Websites say cookies are blocked - Unblock them.

Note that current Firefox version have a third choice for third-party cookies "From visited" to avoid getting to many third-party cookies.

Did you check the startup setting?

• Tools > Options > General > Startup: "When Firefox Starts": *"Show my home page"

Try to use "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit) to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar.

Third party cookies are NEVER and tried exiting FF from File>exit and it still says enable cookies. Request for me to call Specialist at Silicon Valley Comcast if this can't be figured out. I may need to call them.

I have tried everything and it doesn't save the two home page tabs. I am wondering if maybe Xfinity Comcast does not allow for two home pages to be saved, although from my research that doesn't seem to be the case.

Did you try to set the home pages via Firefox/Tools > Options > General?

If you only open both pages in tabs then you can click the "Use Current Pages "button.

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History > Show All History" or "View > Sidebar > History") or via the about:permissions page.

Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks, cookies, passwords, cache, history, and exceptions, so be cautious and if you have a password or other data from that domain that you do not want to lose then make a note of those passwords and bookmarks.

You can't recover from this 'forget' unless you have a backup of the involved files.

It doesn't have any lasting effect, so if you revisit such a 'forgotten' website then data from that website will be saved once again.

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem.

Cor-el - I thank you so much for your info, however, not being tech savvy, it looks very intimidating to me to create a new profile. At this time, I am going to use Xfinity in FF as my home page and then open my emails. I will just keep both tabs open until I need to restart my computer, which is not something I need to do multiple times during the day. I will continue to try to save both pages as home pages and maybe one day it will just "work." Thanks again!!
