@Thane: Thanks so much. This pretty much disconfirms my working hypothesis, at least for Thunderbird -- that going into Expo view is necessary to trigger the problem -- but disconfirmation is useful information nonetheless.
This seems to be a nasty bug in that I suspect it's going to be a hard one for the developers to nail down. It's specific to Mozilla software, and seems to be a bad Mozilla / Unity 3D / Compiz interaction, possibly also specific to certain video drivers (as not everyone has this problem -- 68 affected users is a lot, but I suspect small compared to the active Ubuntu user base who would take the time to report it). So, the more we can do to narrow down the boundary conditions -- or define some usage case that _always_ causes the problem for all users affected -- the more we can help the developers isolate the problem (obviously). Unfortunately, I'm not sure what to suggest next, although one question does come to mind: Is anyone having this problem with a _fresh_ install of Oneiric (11.10)? (I for one upgraded from a 11.04 fresh install to 11.10 on its release date.) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/872207 Title: When Firefox is running in Unity, drop-down menus sometime close when opened Status in Compiz: Confirmed Status in Unity Distro Priority: New Status in “compiz” package in Ubuntu: Confirmed Status in “firefox” package in Ubuntu: Confirmed Bug description: This is something which used to happen regularly though not always (I switched to using fallback mode for a while because of it). Basically, drop-down menus in Firefox such as RSS feeds (or in Natty without the global menu the normal application menus were affected too) are simply not shown when clicked on. Context menus also fail to appear. This often disappeared for no apparent reason after I had used Firefox for a while. I haven't seen it for a while, but it has just re-appeared, possibly because I started Unity as "unity --replace" since I am currently testing an application's behaviour with different window managers. I'm sorry if this information is a bit threadbare. Please let me know if I can provide any additional helpful information.
