feedly memory leak or database corruption?

Feedly begins to slow down firefox a LOT. Every 10 seconds or so my hard drive starts going crazy, freezing the computer for about 5 seconds. This even happens when feedly isn't "loaded" in a tab. I had been using feedly with no big problems for couple of months, but after the last usage of feedly, this problem started. Also, when using feedly that last time my memory usage in firefox spiked a lot, up to 250k memory in use with only 1 tab loaded.

I finally figured out it was caused by the feedly addon after disabling all of my addons one by one.

At the moment I have feedly disabled so that I can use firefox for other things until this problem is solved.
