When I start a Firefox session, it tries to 'restore from crash' but there was no crash

When opening a new session, Firefox (29.0.1) tries to restore a previous session -- even though I have that setting disabled NOR was the last session ended by crashing.

Sometimes it's the session immediately previous, but sometimes it reopens pages that I haven't visited in over 24 hours.

Does Firefox say Restore From Crash? Are you sure there was no crash? Please follow these directions to check.

We're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.

Make sure that Firefox closes properly.

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.

You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.

Rename (or delete) the #sjs and sessionstore.bak# files and delete possible numbered sessionstore-##.js files in the Firefox profile folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).

Does Firefox say Restore From Crash?

Actually, before posting here I tried to find a solution, and in the process was directed to the Session Manager add-on. It was that add-on which gave me the crash message. Behind the add-on window, however, was this message from FF.

Enter about:crashes in the Firefox address bar and ... copy the 5 most recent Report IDs that start with bp-

This shows no crashes since 30 March 2014, and only one with the prefix 'bp-'. Top six on the list

'bp-' entry for copy paste (if needed):

I'm afraid you lost me with that last one.

Oh, about the memory on that three month old crash report on an older version of the browser. Yes. That doesn't really seem to pertain to the problems I'm having now with the newest version of FF?

I meant you lost me on the "Please remove, Firefox hanged". Is that instruction for me (and, if so, crypticmuch?) or some forum shorthand about which I don't need to worry?

Sorry, My Firefox hanged, and I ended up posting the same message twice. I was asking for the moderator to remove that message.

If you have no memory issues now, Great !

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Did this fix your problems? Please report back to us!

I'm very diligent with the malware hunting, cross-checking with several (not all at once, of course) programs including MSE and MalwareBytes, so I don't think that would be the problem -- but I'll run through the regimen again just to be sure.

FWIW, I haven't had the problem today -- actually, it only happens 1 in 10 (or so, I haven't actually been tracking it that exactly) times I start up the browser. So, it's more of an annoyance than an OMFGWTF, Firefox!?!?!?!1!?! thing. :)

Thanks for the help.

That is good, but sometimes they sneak in anyway.

Next time you have the problem, (hopefully never) try to remember what was going on.
