Firefox is using 4GB of vram

I upgraded to firefox 57 yesterday and noticed that I had a lot of microstutters when playing games while having firefox run in the background. Upon closer inspection I noticed that firefox was using nearly 4gb of vram. Most of it in one of the processes. At the time of the attached screenshot i was not watching or buffering any videos. I had around 30 tabs open (only around 20 of which were actually loaded) but still 4gb is quite excessive in my opinion. I already tried a refresh but it is still eating the same amount of memory.

Upon further debugging I noticed that there seems to be a memory leak somewhere. GPU memory usage increases each time I am refreshing a page. In fact each time I am refreshing this page here firefox will use around 1mb of additional GPU memory. Also opening the attached screenshot and closing the popup will use up an additional 200kb each time.

Edit: I also tried closing all tabs. Which resulted in firefox still using around 3GB of vram as can be seen in the attached Screenshot.
