Can't restore previous session tabs after Firefox crash using Firefox 95 on Mac

I have consulted https://support.mozilla.org/en-US/kb/how-do-i-restore-my-tabs-last-time. That article says:

-Click on the menu button [three lines at the upper right] to open the menu panel. -Click History. -Click Recently Closed Tabs.

I am using Firefox 95.0.2 for Mac (iOS 10.15.7). There is no "Recently Closed Tabs" option to click after clicking on History per the above instruction. I have saved various files from the time of the crash, in particular "previous.jsonlz4" (a 20.6 MB file, as I had a very large number of tabs open). Is there any way to use this or some other file to restore my old tabs?


/moved thread from Firefox for iOS (for iPhone/iPad) to Firefox (desktop) section as you have macOS.

Thank you, James, for moving the thread. Also, I have just discovered what actually happened yesterday that resulted in the "loss" of several years' worth of tabs. I must accidentally have clicked on the "OneTab" icon in the toolbar in the upper right, with all of the tabs "disappearing" into OneTab! What a huge relief! My apologies for bothering anyone with this post, which should be considered "closed" (though I don't know how to do that from my side). I have now moved the OneTab icon into the Overflow Menu to keep that from happening again.
