It also has the problem that sometimes others Flash windows goes slower (me watching a youtube video for example in another tab). this is with the new Firefox 3.5. I did not have this on the previous version of Firefox 3 Reproducible: Sometimes Steps to Reproduce: 1.use the Livestream Studio (log in) or something that is made of all flash and that wastes many CPU usage. 2.Open another Tab 3.try to press on the Bookmarks and move the mouse to folders or to write something in the Address bar and wait until it gets the results (that will apear blank but some will show) Actual Results: the results looks with no words but some does show. I am running Win Vista Home Premium, with Firefox 3.5. it is a Laptop, Intel pentium Dual-core.
