I need to use Spotify's web player because I cannot install the player on my work PC. Unfortunately I have noticed that after 30 mins - 1 hour of continuous play, Firefox starts lagging; a few moments later it either completely crashes or freezes.
Most of the times I solve by terminating FF from Windows task manager (ok, task manager is not the most reliable method, but it can provide an idea of what is going on) and when I do so, I find that FF is using 60-70% or the available RAM.
I never experience this behaviour when I am not using Spotify, making me suspect that the site is leaking memory.
Is there some option in the website (or some other method, maybe with Greasemonkey?) that can solve or mitigate this problem?
