Firefox touchscreen support

[afmma...@gmail.com]

Hi,
I have a Dell 7359 touchscreen laptop running Ubuntu 16.04. I'm running firefox 49.0.2 and all touch inputs are being treated as if i am just left-clicking and dragging. Google Chrome and other apps can differentiate between pinch-zoom, touch scrolling and a finger tap.

I thought that maybe touch input wasn't supported in Firefox but I have used Firefox on a Windows touchscreen PC.

Any suggestions?

I read that Firefox's touchscreen support requires e10s (Multiprocess
Windows) in order to work. Go to "Help >> Troubleshooting Information"
and see whether "Multiprocess Windows" is enabled. It is shown in the
first table, at about row #13.

If e10s / "Multiprocess Windows" is shown as enabled and touchscreen
support still isn't working, then check out the other suggestions at
https://support.mozilla.org/en-US/questions/1091627

If e10s / "Multiprocess Windows" is shown as disabled: One of the
catches is that e10s / Multiprocess Windows is not compatible with some
extensions. In Firefox 49, e10s is only enabled when your extensions
are all white-listed. Here in Ubuntu 16.04, e10s is disabled unless I
disable the "Ubuntu Modifications" extension.

You can try disabling extensions which are not known to be compatible.
For a start, see the list at "https://www.arewee10syet.com/". You could
also try to force-enable e10s at your own risk -- see
https://wiki.mozilla.org/Electrolysis#Firefox_Release

Disclaimer: I do not have a touchscreen PC myself.

I do an HP ENVY 15 inch touch screen and it works fine with both its
original windows 8.1 and windows 10 Professional.

As I read the original post, afmmancini was asking about Linux (Ubuntu
16.04) and had it working on Windows.

My expectation would be that e10s is enabled in your Firefoxes on
Windows but not in the OP's Firefox on Linux (Ubuntu 16.04), and
that is the reason why it works in your systems but not in
afmmancini's Linux system.
