I recently noticed that the menus and dropdowns in Firefox 3.6 were *extremely* sluggish on my laptop running Slackware64-current. For example, if I click on "File..." or one of the folders on my quicklinks toolbar, the menus take about a second to appear. No other apps are affected and surfing is as fast as usual.
I'm running Slackware64-current on a Fujitsu Lifebook V700. I typically use the Xfce window manager, but was able to repeat the problem in Blackbox.
I uninstalled the Firefox 3.6 package from -current and reinstalled the Firefox 3.5.2 package from the slacware64-13 tree and it works fine.
I've been scanning the net for others having this same problem and to my utter shock I can't seem to find anyone else reporting remotely the same problem!
I'm fine using Firefox 3.5.2 indefinitely, but it's driving me nuts that I can't figure out the source of this problem!
CHANGES AND HINTS.TXT contains this, which may or may not be relevant:

If you notice Xfce's Terminal and perhaps some other applications being drawn
very slowly in X, then you should try explicitly disabling the Composite
extension in /etc/X11/xorg.conf, or set XLIB_SKIP_ARGB_VISUALS=1 in your
environment prior to starting X. For more information on this, see: http://bugzilla.xfce.org/show_bug.cgi?id=2792
We've also gotten a report of some other things (such as VirtualBox) that
might benefit from this.
My bet would be it's one or more of your addons, or some interaction of same. Try 3.6 in -safe-mode and see how it runs.

I first noticed that there was a build of Firefox 3.6, called Swiftfox, that is noticeably faster than the generic Firefox. It is 100% compatible with Firefox; looks the same, behaves the same (except for the response time). I have built a package for Slackware, and I can send it to you if you desire.

Any thoughts?

I have seen this exact thing on my machine. I cannot explain why, and know that it's technically impossible, but it only happens to me when wicd is running. As soon as I stop the wicd service (and start networking via. rc.ient1), and re-launch xfce, my GTK menus are back to normal.
Again, no clue why, nor have I had time to delve further into it, but it was 100% reproducible on my laptop.

good call! The problem goes away when I use the rc.wireless script instead of wicd...
What could cause that (anyone...)?
Also, no error messages when I launch firefox from the terminal.
This is probably not related but I'll just throw it out there. Have you disabled ipv6 either through blacklisting the ipv6 module or by disabling ipv6 in Firefox's about:config? ipv6 has led to slowdowns for some, and though I don't have wicd installed to check the script I'm just thinking that maybe it is enabling ipv6 somehow. Probably incorrect since I can't test wicd on my desktop.
I tried setting network.dns.disableIPv6 = TRUE in Firefox about:config with no luck. I do have the ipv6 kernel module loaded but rmmod won't let me unload it as (according to lsmod) there are 12 somethings (?) depending on it...
I'm running Firefox-3.6 under XFCE with wicd on -current64, and I haven't seen any issues on my box. Have you installed everything else from -current64, or are you only running Firefox-3.6 from -current64?
I see similar ff 3.6 behavior in my system. Reproducible by selecting a bookmark toolbar item, then middle-clicking a drop-down item to open in a new tab. Subsequent clicks on the toolbar then won't respond until the newly opened tab has partially loaded.
My system is running ubuntu 9.04 but with a 2.6.33 kernel and more recent xorg. Interestingly, when I was googling for info about this problem, I found several windows users complaining of the same thing. Is it possible there's a common ui bug?

I'm running everything from -current64 plus Alien Bob's 32-bit compatability libs and a handful of other packages (mostly Slackbuilds):
