334253 - MacOSX: Vertical scrollbar sometimes sticks when in top-most position

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Chris McAfee]

Firefox 1.5.0.2
osx 10.4.6
ppc g5

This is a weird scrolling bug.  Some pages have a "sticky vertical
scrollbar" if the scrollbar gets to the top-most position.
I saw this happen just now on www.cartalk.com, and can reproduce
after restarting Firefox.  This doesn't seem to be a function
of tabs, and I don't see any obvious JS errors.

I can also reproduce this on a ! bugzilla list, make the
window smaller, move the vertical scrollbar to the top,
let go, then try to scroll down.  The behavior I am seeing
is that I can't drag the scrollbar down, I have to "page" it
down or use arrows to get it out of the top position,
then it starts working.

I think FF on Mac treats "Z-Index" and "visibility" poorly - specifically it forgets to actually apply the z-index or visibility to the scrollbars.  But by using style.display = 'none' and style.display = '', you can make the scrollbars disappear properly

The scroll bar slider gets stuck at the bottom of the scroll lane forcing the use of the up selector to unstick.  This is not intermitent; but, consistent whenever I reach the lower limit.  The Firefox version is 2.0.0.4 and the MacOS is 10.4.10 (the problem was also present in earlier versions of MacOS 10.4).  The system is a dual 800 MHz PowerPC G4 Quicksilver w/ a dual 1.73 GHz PowerPC G4 7448 upgrade (the problem was also present before the upgrade).

This bug is part of a query for Firefox bugs that have Status set to NEW, but have version field set to 2.0 or older and have not changed in over 800 days.

If you still see this bug, or if it is still valid with Firefox 3.6.10 or a firefox 4 nightly build, please update the version field and steps to reproduce.
