Description of problem: If horizontal scroll from a pointing device is enabled in OS, X11, and Firefox, then Firefox scrolls backwards. Version-Release number of selected component (if applicable): 3.0-0.beta2.12.nightly20080121.fc9 How reproducible: 100%, easy Steps to Reproduce: 1. First you must establish that your pointing device works correctly. This step ensures that you don't have your buttons remapped inside X to suit Firefox 1.1 Open a text file with a 80 character line in gedit (actually any app will work, only Firefox is backwards, but let's use gedit) 1.2 Go Preferences->Editor, uncheck "Wrap" 1.3 Return to text. Move horizontal scroller, verify operation. For example, on a laptop with Synaptics, moving finger to the RIGHT will move the SCROLL TAB to the RIGHT. Compare with the operation of the vertical scrollbar, it should be the same. If you scroll backwards at that point, fix it in your X setup 2. Run Firefox 2.1 Go to about:config, set this: mousewheel.horizscroll.withnokey.action;0 2.2 Verify that every other mouse setting is at default 2.3 Find something wide, like Red Hat Bugzilla 2.4 Narrow the browser window until horizontal scroll-bar appears 2.5 Scroll it, verify operation It's backwards Actual results: Horizontal scrolling is backwards Expected results: Horizontal scrolling same as all other GNOME applications Additional info: This is NOT a regression in Firefox 3. It was like that for years, but finally I figured that it's not going to get fixed by itself unless I report it. BTW, keep in mind that at least in GNOME the X cursor has to be inside the window or the scroller won't work. Even menu or tab areas of the browser are no good.

Couple of questions -- if you really want to have this fixed soon, than probably the best thing you can do is to file a bug in the upstream bugzilla (http://bugzilla.mozilla.org). We are now fully immersed in making FF3 working at all and anything which at least slightly resembles upstream development has to wait. In order to be sure that we know what's going on in the computer, could we get output of this command in the moment you did moving with the touchpad? xev 2>&1 |tee xev-log.txt And then please attach xev-log.txt to this bug. Thanks a lot for your help with fixing this problem.
