A single Firefox window with many tabs will not appear, yet other new windows will?

I've had this problem a few times before. .

Whenever I start up the browser, the one window with most of my tabs, about 30+ of them stays stuck in the taskbar. I know that the pages are loaded, yet for some reason, which I think may be that a single page has prevented the whole window, with all of the important tabs from appearing, to be the case.

So I was wonder if there is anyway to fix this while saving my precious tabs?

I can open up new windows by right clicking on the stuck window in the taskbar, which I have done in order to ask for help on this issue. I hope that this is understandable enough, thanks.

Please continue in your other post if you still have problems after deleting the below mentioned files or with a new profile.


It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.

Delete the sessionstore.js [2] file and possible sessionstore-##.js [3] files with a number and sessionstore.bak in the Firefox Profile Folder.

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