I'm using Firefox mobile since it's release and haven't observed this issue. For years now I have so many not-closed tabs that FF just shows infinity sight instead of a number, so it's not that I'm limiting my browser use in any way. And I never force close any of my apps ever.
I did encounter memory leaks on my desktop Firefox and every single time it was a particular shitty site (for example the latest one is our corporate Jenkins). I suggest you check your sites, find and close the offender. Do you maybe use some fat portals like mail or chats in the browser? They may request OS to stay in memory to provide user a service of constant up to date communication.
