Synaptics trackpad won't scroll on Mozilla Firefox/TB.

This question is answered

The newest version of Synaptics track pad for the XPS 17 (L702x) does not scroll on any Mozilla applications; that goes for Firefox and Thunderbird mail. All other stuffs like Internet Explorer, MS Office applications, etc scrolls fine. I tried an older version of the touchpad driver or one directly from Synaptics and it will work, but then the Fn+F3 key won't disable/enable the pad. We need an update on the driver.

  • Try this, it worked for me. Using RegEdit (so be careful not to break more things than you fix), create a DWORD entry called UseScrollCursor in [HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPEnh] and sets its value to 0, then reboot your laptop, You should be able to scroll with your trackpad after that.

  • Hi 80sGuy,

    Welcome to the Community. Have you tried uninstalling the driver and then try reinstalling it? To uninstall, click on start, right click on computer, click on properties, click on device manager, click on the symbol next to Pointing Devices, right click on Synaptics Touchpad and click on uninstall, click ok to confirm, once its removed use the below link to install it.

    Hope this helps.

    Thank you

  • The driver that came with my computer is OEM Ver: 15.3.22.0. It is so new (along with the BIOS: A14) that it's not even listed on Dell's support site yet. I have tried the version from your link but the FN+F3 key does not disable the pad. I've also tried a version from the L701X, and finally I gave up all from Dell's and decided to use one directly from Synaptics. The only annoyance is that the FN+F3 key which supposed to disable/enable the pad is obviously not working since it is not embedded with any of Dell's program. It's not a really big deal since I hardly turned the pad on/off anyway. Also, if I need to, I can control it through the 'Quickset' function, but the problem would be turning it back on since I can't use the cursor when the pad is disabled. I'd have to navigate using the TAB key from the keyboard to get to the button and hit ENTER.

  • Oh, sorry Royan and thanks for the suggestion, but Dell definitely needs to take care of this issue.

  • I have NO IDEA where to begin to create such list of numbers!

  • Sylvain,

    I had decided to 'carefully' duplicated your instructions and now it is working!

    Thank you.

  • THIS finally solved my problem on my Dell XPS 17. This Dell was delivered February 2012 and scrolling in Firefox was not possible.

    Many many thanks!

  • Hello Sylvain,

    Thanks for your suggestion. It helped me and others a lot. 

    Only the other day I learned that the touchpad still isn't working in the agenda of outlook.

    Do you have any suggestions to tackle this problem?

    Best regards.
