Take a look at https://bugzilla.mozilla.org/show_bug.cgi?id=213534 This is a two-year-old bug, where closing a tab doesn't release memory.
Firefox doesn't really suck, but this bug does, and I'm getting desperate enough to use any forum I can to spread the word about it.

That's the problem; I'm a user, here, not a developer.
Whether it's technically a memory leak that closing a tab doesn't release memory doesn't change the fact that it's a problematic situation.
Obviously, the best way for me to get the bug fixed would be to figure out who actually owns the relevant piece of code... which is more hackery than I would prefer to do. It is, certainly, a possibility down the road, particularly if I fail in my cheap, thuggish campaign to bring the bug to the attention of the powers that be.
