I have that issue myself but I just use an add on or extension that unloads the tab when I’m not using it, or something like one tab where I can store tabs indefinitely “just in case” and ease my tab hoarding mind. Cause I don’t wanna bookmark the tabs, I prefer to use bookmarks for important links or ones I revisit regularly, I just often don’t know if I might need a tab one more time again in the future, or might plan to go back to it eventually, so I need a different method to manage it.
