Do you happen to keep the Web Developer Tools open?  Or console logs
set to persistent?  Those will keep lots of things in memory just in
case you need them as a developer trying to debug an issue.
Generally, if I notice my memory usage going up, I will be sure to
close the Dev Tools and reload the tab a couple of times.  Then,
eventually, the JavaScript garbage collector will kick in and start
releasing the items the Dev Tools have stopped tracking.

FF also has built in performance tools that can be used to determine
what may be using resources.  Menu -> More tools -> Task Manager (aka,
shift-esc or about:processes).

Nothing Debian specific here.
