Does this only happen when you close and restart Firefox or already during a browsing session?

In case you are using "Clear history when Firefox closes":

• do not clear the Browsing History

• Tools > Options > Privacy > Firefox will: "Use custom settings for history": [X] "Clear history when Firefox closes" > Settings
• https://support.mozilla.org/kb/Clear+Recent+History

Note that clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, and passwords.

Both the history and homepage issue happens during browsing.

Nope, I am not using clear browsing history.

The homepage issue - I have more info on this - if in the the homepage text box, I used a site that was in the dropdown auto-fill selection, it would not stick - as soon as I picked another tab or clicked ok, it would revert back to the default firefox start page.

If I enter a page in manually that is not recognized in that autofill selection dropdown, the page will stay.

Or if I use "use current page", if it is a page that is new or not recognized, it will stick. But, if it is a page that will be recognized by autofill, it won't stick.

Hope that is clear and makes sense.

Thanks for responding so quick!

I should also add this...

If I open other tabs and visit sites and then close them, these pages will show up under the recently closed tabs, but again they won't appear in the history themselves.

ok - crazy - but now that I worked out the homepage issue and have it going to a page that wasn't in the dropdown - I restarted FireFox and it is now remembering the history correctly. However, all my old history has been wiped - it looks like it is all deleted. I did not delete it.

The only other change that happened when I restarted FireFox this last time was the Adobe Application Updater updated itself and also updated Adobe's Camera Raw.

Anyway, it seems to be working now -so that is great!
