ExtJS 5 is broken in Firefox 52 when laptop has a touchscreen
In Firefox 52 Touch events where re-enabled, which seems to cause a lot of trouble in ExtJS 5.
The most annoying exampel is that you can't open a combobox list.
STR: On a laptop with touchscreen (or modifying source to have Ext.supports.TouchEvents returning true) open https://fiddle.sencha.com/#view/editor&fiddle/1s9l and try to open the combobox by clicking on the arrow.
Expected result : The list open
Actual result: The list does not open
I can spot several Ext.isWebkit tests along those on supports.TouchEvent , and I think one of them in Ext.event.publisher.Gesture might be the root of the issue :
Code:
if (!handledDomEvents.length || (supportsTouchEvents && Ext.isWebKit && Ext.os.is.Desktop)) {
handledDomEvents.push('mousedown', 'mousemove', 'mouseup');
}
Because if you don't add those, only the touch events are handled. So if you're on your touch-capable laptop, but using a mouse, you can't interact with anything.

We also have a case where the user can't scroll a panel (the scrollbar is not even displayed) on a touchscreen supported device.

We are also facing issues. Our application got a web desktop. Where we are not able to open start menu as well as not able to open any window by clicking icons on desktop.
Also sencha web desktop example does not work.

Looking forward for any quick solution to this problem.

I saw same issue posted for Ext 6 and an override provided there seems to be working for Ext5 as well.

Got the click issue fixed with an override from Sencha, but still looking forward for scrolling issues.
Its a bad show stopper for our production, either its Sencha framework or browser release.

Hello,
It would be greatly appreciated if we could have some information about this issue, if it will be fixed and if so, when, so we can go back to our consumers and tell them.
It's a bit harsh to be left out of the blue here, it hurts not only ExtJS but also Firefox.
Thanks for your understanding

We still have the problem with the scrolling in Firefox.
Is there a solution?
We need it in extjs5 not extjs 6.

For us, the problem solved itself after firefox update, we could not get anything from sencha neither found anything ourself.
