Firefox will not restart old session

It began a few days ago. I had started up firefox expecting my old session to turn up, as I had selected the settings for it to reappear. However, I was given a tab with a video about firefox, a tab with the firefox homepage search engine, and every time I open a fresh new blank tab, it gets redirected to some strange address which the servers cannot actually find. I ran malware and spyware, and got rid of stuff, but the sessions will not reappear unless i manually select things in the history, and the all the settings i changed in firefox reset to defaults.

Did you check the startup setting?

  • Tools > Options > General > Startup: When Firefox Starts:

Show my windows and tabs from last time

I do that every time. It still sends me to a Firefox search engine page, and I have to click on restore session.

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

Delete the sessionstore.js file and possible sessionstore-##.js 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).


Do a malware check with some malware scanning programs on the Windows computer.
You need to scan with all programs because each program detects different malware.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.
