I reported LP:502367 a while back, but there's been no response (and nobody has confirmed it). Could some visit http://www.adobe.com/, try to hover over the menu and see if the menu is hidden under the flash content?

Bug on Launchpad:> This is a regression from lp:49613. Using Firefox 3.5, on http://www.adobe.com/, when I hover over "Solutions", the menu is partially covered by the flash object.
This was fixed in Firefox 3.0, however I am still facing this issue in Firefox 3.5. Bug 49613 claims this was fixed for Firefox 3.
I'm using Firefox 3.5.6 (3.5.6+nobinonly-0ubuntu0.9.10.1) on Ubuntu Karmic Koala 9.10 and Shockwave Flash 10.0 r42. It still affects me on Firefox 3.6.
