"Scrolling within a list of bookmarks doesn't work."

Three different displays of bookmarks list, which one?

1. Menu bar drop-down
2. Library window
3. Bookmarks sidebar

The Menu drop down bar and the Bookmarks sidebar.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do not click the Reset button on the Safe mode start window or otherwise make changes.

Thanks for the reply.

Tried safe mode. Problem still persists. Disabled all plug ins. No change.

Anything else I should try?

Update. The problem occurs in any drop menu.

Any help much appreciated. I'm sure its hardware related as I'm using windows 7 64 bit on a HP 8460. With windows XP I never had a problem. It's getting to the point where I prefer not to use FF which is a shame.

Same problem here on two different HP laptops. I really hope Mozilla can fix this problem, maybe in collaboration with HP. It must have something to do with HP's hardware customization. HP do their stuff their way and customers suffer. I've had no such problem on any other laptop and they were all using Synaptics touchpads.

I have lots of Bookmarks and it is really annoying to wait for them to scroll automatically with the cursor placed over the little arrow bar at the bottom of Bookmarks dropdown list. If you use an external mouse, you can scroll through Bookmarks with it just fine, so the problem is with the touchpad.

I have now found a proper solution. Turns out Firefox and Synaptics don't like each other too much. The scrolling problem has been going on for years in one way or another and neither side seems to care enough to provide a permanent solution.

I have found a registry fix in one of the older debates about a similar problem. My addition to the fix is that you must make sure that Vertical Scrolling is enabled in Synaptics preferences. It may seem like it is, but the registry fix won't work unless scrolling is really enabled. Once that is confirmed, all you have to do is to add this registry entry into [HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPEnh]: "UseScrollCursor"=dword:00000000

If you don't know how to do it manually, just create a .txt document on your Desktop, open it and copy/paste this into it:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPEnh] "UseScrollCursor"=dword:00000000

Save it as a .reg file, then double-click it and confirm the action when promted. Restart Firefox or even Windows and there, Bookmarks scrolling now works!

I would recommend you to use the drivers provided by your laptop manufacturer, even if they are older than what Synaptics have on their website.

Madaloas - Thanks for sharing. I will try your solution and report back.
