Comment 3 for bug 120991

I don't use desktop-effects, only the murrina theme. Normally, the behaviour occurs using my WLAN USB stick (Zyxel ZyAir g-220 with Feisty driver) when opening a new tab and there a site with many effects (e.g. the German page www.web.de). During log in to my e-mail account at web.de (SSL) it takes very long to finally log in, and every move within the mail account takes very long. The 2nd situation is when I am away leaving the laptop running (no energy saving tool) with finally the screensaver switching on. After a while, when reactivating (mostly to look something up in google - I had to learn for an exam) FF seems to hang immediately after opening a webpage (FF was on during inactivity, but it occurs also when re-opening FF after closing it completely). I don't know if this description is useful for you, I hope so.

Thank you!
