BUILD: Current trunk Firefox build STEPS TO REPRODUCE: 1) Start with a vanilla profile 2) Install enough extensions that in the Add-On manager there are a few out of sight below the bottom of the window. I have Adblock Plus, DOM Inspector, Google Safe Browsing, Leak Monitor, XForms, Nightly Tester Tools, Web Developer. 3) Scroll down all the way to the bottom of the list. 4) Select the last item. ACTUAL RESULTS: The window scrolls up a bit. EXPECTED RESULTS: Stay scrolled all the way down so that I can see all of the item I just selected.

Please try duplicating this with the download mgr... I suspect you are able to and this is an Toolkit XUL Widget bug that is not due to bug 329045 and has been present on the trunk since bug 328881 was checked in.

fwiw, my personal guess is that this has to do with the listbox item resizing itself... As in, we scroll to the "top" of that item, but then it gets bigger after that.

I can't reproduce this on the 1.8 branch - I can on the trunk. I suspect this is due to bug 328881.

Boris, do you want to keep the request for blocking-firefox2 since it doesn't affect the 1.8 branch?

I can reproduce in the download mgr which is available in Tools -> Downloads - this is pretty noticeable. It will probably be easier to find this in the current Product and Component so I am leaving them alone though they aren't correct. Should be Toolkit -> XUL Widgets since it affects users of the richlistbox on trunk. May change later but I suspect that after bug 334765 is fixed this will also be fixed which will hopefully be soon. I'm compiling now to verify. This has nothing to do with bug 329045 and was caused by bug 328881... changed blocking accordingly.

This is fixed by the patch in bug 334765.

This appears to be fixed by the checkin of bug 334765. Anyone confirm?

Resolving wfm though this was fixed by bug 334765.

Yeah, this works now.
