1276695 - Zooming in/out not working on touchscreen Dell laptop,Ubuntu(14.04) but working with another browser

Status: RESOLVED DUPLICATE of bug 1245183

(Core :: Panning and Zooming, defect)

Description

[meena24dhanani]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:46.0) Gecko/20100101 Firefox/46.0
Build ID: 20160511224433

Steps to reproduce:

I logged onto a website and tried to zoom in using touch on my Dell laptop, having Ubuntu(14.04). I also tried the same using another browser.


Actual results:

Zoom in did not work, instead it started selecting random text on website because of the touch. But the other browser could zoom in easily with touch.
So problem may not lie in Ubuntu or my laptop.


Expected results:

Firefox should have been able to zoom into the content on the website.

To use touch input, you have to set MOZ_USE_XINPUT2=1

ah, SupportsApzTouchInput isn't implemented in GTK3.

That's a good point, we should fix that - I'll file another bug for it. However it's unrelated to the actual bug here. Pinch-zoom is not supported on desktop at the moment, we have bug 1245183 on file for that.
