Netscape has been Firefox since version 7 so any anomalies you would find in FF is the same as you would find in NS. The only difference between the browsers is the visual layout (colours and skin).
As far as the scroll bar not working on FF it does work but the way the
frames are laid out code is written it is obscured by the
frame improperly marked up <div> next to it. You have to actually just catch the far left side of the scrollbar and it should work. If you hover your pointer over the scroll handle you should see the handle change colors.
The problem is that the element that is used to enable resizing of the tree (div.#treeSplitter) is overlapping the scrollbar. This can be fixed by changing a line in /manager/media/style/template_you_are_using/style.css at line 527 (depending on which manager template you are using) to make the right position to -10px insead of 0. It should read as follows:
#treeSplitter {
width:10px;
height:100%;
position:absolute;
right:-10px;
}
This should not interfere with any other elements as the manager main pane has no elements within the 10px space that this moves the treeSplitter to.
If anyone wants to test this out and get back to me here on how it works in various browsers/OSs so that I can submit a patch for 0.9.6.x.
I certainly hope that you are not thinking of switching to using IE for your development and management as is has more holes than a sponge. Firefox is not the problem, the problem is invalid code the treeSplitter is not in a valid element the empty div is marked up as <div /> and not as <div></div> as it should be. Firefox just doesn’t know how to style an element that doesn’t actually exist so it can’t do it correctly.
Hope this all makes sense.
