At the moment, if I leave
https://developers.google.com/chart/interactive/docs/gallery/linechart
open in Firefox (40.0.3/Win8/64) for a few hours, it begins to consume surprisingly large amounts of memory. It goes from ~50MB to 500+MB as shown by about:memory ...
In addition, creating a large linechart (example attached) and reloading it leaks large quantities of memory.
I really have no idea where THAT problem is although offhand it seems like reloading a page shouldn't be leaking memory.
I don't think these issues are necessarily related. The first case, the page grows to a very large size. The second case, Firefox reports increasingly large amounts of uncommitted memory.

Joseph,
We've fixed several memory leaks for the next release, which we will start pushing out within a week.
The memory leaks shouldn't survive a page reload, however, so what you are seeing in Firefox sounds like a problem with Firefox. The chart-related memory that is leaking within the page is attached to the window/document, which should be detached when you reload the page, and thus it should be garbage that can be collected.
