When you say you get a new tab, do you mean the page with tiles for sites in your history, or a completely blank tab?

There were a couple of posts last week that the home page wasn't loading at startup, and the user needed to click the Home button to display the page. Does that seem to be the same issue you're having?

In the following thread, clearing a settings file (renaming prefs.js to force Firefox to return to many default settings) resolved the issue, but that's a bit drastic, so we might do a little more troubleshooting first... When I open Firefox it does not go to my home page even though my setting are set to go to home page when Firefox is opened.

A blank new tab is what I get. if I click the home button it does go to my home page. The issue is when the browser opens.

sorry...and to answer your other question.."There were a couple of posts last week that the home page wasn't loading at startup, and the user needed to click the Home button to display the page. Does that seem to be the same issue you're having?" Yes. I don't get the default homepage..say Yahoo.com.. I get a Blank New Tab as a home page. But as I mentioned if I click the home button it does goto the expected Yahoo.com page. Hope I made it clear :-)

Currently I don't have a clear idea of what causes this. If it becomes intolerable, you could try the approach that worked in the other thread. Please keep the old prefs.js file (for example, rename it to prefs-old.js or copy it to a different folder) in case there is any irreplaceable data in there.

I just completed doing that. I rename prefs.js in proper folder shown by Help-Trouble-shooting Information and closed the browser. I restarted the browser again and despite a few tabs coming up the first time and having close those and having to reset my default home page it now works 100% all the time ( 30 opens and closes) and I can't see any other negative side effect. I also checked and it did create a new prefs.js. So I am thinking somehow the 44.0 update and a combo of something else perhaps messed up that file. All good now.. I hope for a very long time. Thanks for taking time out to help me. Appreciate it.  :-)

Thanks for the update.

If curiosity gets the better of you, you could look in the file at the customized settings (right-click > Edit, don't double-click), but it's probably a needle-in-a-haystack situation.

There is a possibility that some of you are suffering from a known bug with Firefox 44. ( _{Bug 1243549 - When I run (launch, open...) Firefox for the first time during a session I get a blank page instead of my usual home page.} )

The defining features of the bug are

• Firefox has been set to clear History on closedown
• An intermittent problem on closedown {You may not be directly aware of that)
• Problems on restarting after the close down issue. This could result in for instance a blank tab displaying.
