Firefox restores my old tabs on start up even if I dont want it.

Hi Mariam,

Thanks for your reply. I implemented what you said. It WORKS at least as far as normal shutdowns are concerned where I quit Firefox normally with multiple tabs open. But there has been no forced shutdown of Firefox due to some web page / java script malfunctioning where Firefox says with a popup : "Force Quit Or Wait" here in the Linux Ubuntu 26.04. I was waiting for that to happen so I can confirm your solution completely works on all cases . I have a feeling it will work then too. Otherwise Ill let you know. But so far so good. Thanks a Lot.

Hi Mariam,

It has happened again. Right now textbrowser.sessionstore.resume_from_crash is set to false as you told me last time. I did it myself. In spite of that, one of the websites that I visited sometimes seems to freeze the app (mouse movement still works) which forces me to close the app by clicking the x box at the top right. Then Linux Ubuntu (I am running in Ubuntu 26.04) says "Force quit yes / no " in a popup. and I force quit. Then when I reopen it tries to reopen the tabs as before. I do not want this.

So the solution you gave works in normal cases but not now. Thanks

OK Jbr, I have implemented your solution. It works now when I close Firefox with multiple tabs and reopen . It opens with a clean slate which is what I want. But I cannot simulate the "Firefox force quit scenario in Linux Ubuntu 26.04" which happens occasionally with some website malfunctioning. When that happens we will see if it works or not. If it works in that case also I will mark as solution. I will let you know. But for now it works. Thanks.

Ok jbr. The solution you gave works even if Firefox is forced to shutdown due to some website having some issue in Linux Ubuntu. When restarted it starts in with a clean slate meaning 0 tabs which is what I want. Ill mark this as a solution.
