The screen you are getting indicates that Firefox has a problem automatically recovering from a crash.

What is Windows set to do when you close the lid? For example:

• Sleep
• Hibernate
• Shut down

From time to time, users have reported problems with Firefox after resuming from Sleep. I don't know whether these problems were fully sorted out. (Hibernate takes a lot longer, but as far as I know, does not have those problems.) Are there any particular sites that seem associated with this problem?

If Windows is shutting down, it probably is killing Firefox without allowing time for shutdown file maintenance. To avoid that you probably have to manually exit Firefox and allow it time to finish (up to 60 seconds) rather than just putting the lid down.

Can you help me with which one of the 3 shut down is which and how I can change from one to another. i do not know how these selection are set.

Try checking here:

Windows 7 Start menu > Control Panel

If you have the icon-style listing, click "Power Options".

If you have the category-style listing, click "System and Security" and then "Power Options".

In the left column, click "Choose what closing the lid does"

Then you can see and, if you like, change what happens when you close the lid.

I have set the power options to put the computer in sleep mode when I close the lid.

This has solved 2 problems. I no longer get the error message when I return to the computer and the computer no longer takes 5+ minutes to boot during a power on.

My only question at this point is is there any harm in never turning the computer off.

Sleep mode still uses battery, so if you're going to be away from it for a few days, you may want to really shut down.

Restarting Windows occasionally may trigger necessary security updates.

I find that after about 7-10 days Windows starts to bog down. Maybe memory is very fragmented or things are going wrong in the background, so restarting once a week -- when it's convenient for you -- might reduce frustration with random breakage.

Does anybody get a crash indicator when they close out Firefox? I have the same problem as Howie E. When I'm done using my laptop for the day and close the lid, the next day I'll get a crash indicator saying that Firefox crashed, But it really didn't I just mainly closed the windows. OR before I close the lid I'll wait a few minutes to see if I get a crash report and I'll get one within 5 minutes after closing out Firefox. This has been an ongoing problem with the last few versions of Firefox, probably going back to Firefox 45 or Firefox 46.

Hi crazycappy01, this thread is already marked solved. If this solution doesn't work for you, please start a new question.

Firefox should either shut down properly or display a crash dialog within about 60 seconds of your selecting Exit from the menu, either:

• "3-bar" menu button > "power" button
• (menu bar) File > Exit

If yours hangs for 5 minutes, I don't know what would cause that, so you might also include crash report IDs in your new question. This article describes how to get those: Firefox crashes - asking for support.
