I have firefox 26.0. After it sits idle for 20 or 30 mins, it shuts itself down. How do I stop this?

None of the previous versions of FF did this. I haven't added any software or hardware, nor made any other changes. I'm using Win 7. As a side note, even though I have my Options set to re-open all tabs when FF is re-started, none come up unless I re-set the 'Homepage' to "Use Current Pages" each time before I shut down. Thx for your help -- Bob

Hello Bob, if you have set Show my windows and tabs from last time, then see if your settings may be incorrect in privacy panel.

Definitely you have too many pages as your home page and probably Firefox take long to start up !

It is not related, but in your system details it seems that you have in your profile folder a User.js file. The user.js file does not exist by default. If you create the file, forget it, if you have not create the file then you can delete the User.js file(some programs create the file also).

thank you

I see a browser.sessionstore.resume_from_crash: False line in the System Details List

You can check if you have an user.js file in the Firefox profile folder that sets the browser.sessionstore.resume_session_once pref to true.
