IOS Firefox app update - lost previous session

I recently updated the Firefox app on my iPhone through the App Store. When I re-opened the app all my previous (many) tabs were closed. There’s no option to restore the session and while I still have history of “closed tabs” it doesn’t actually show the tabs the were closed as a result of the update, just the tabs I had closed before the update occurred. Since I’ve had some tabs open for a long time and I open and close tabs very often looking through my entire history isn’t a very viable solution. Is there some other way to restore my previous session like there is in browser?

I’ve never had an issue like this before on my laptop/windows. Thank you for your help.
