Problems finger signing with Firefox and IE on PC

What I have tried: I have replaced signature_pad.min.js with the newest version from the website: https://github.com/szimek/signature_pad

This was updated to address a problem with touch events. Now, Chrom and IE are working fine but I continue to have issues with Firefox.

A better explanation of the problem:

In Firefox, the signature pad displays on the screen, but apparently the touch events from the touch screen are not forwarded to the signature pad event handler (in most cases). Instead, the whole page is being moved up/down.

In other cases, if I am persistent, I can get it to register some strokes (right to left registers best or if making a C and continuing without lifting my finger I can squiggle all around but it does not seem to register an Up event or off because if I start another line or squiggle it will connect both drawings with a line).

So, any ideas about how to fix this in Firefox?

More observations about Firefox
I see problems with it both on the PC and Mobile in reference to moving the page rather than writing in the canvas when using touch input (finger). On the PC, pen input and mouse input work fine. On the mobile device, Firefox registers very poorly (unreadable) for both pen (Samsung Note) and finger input.

Now I have tested it on Surfari and it works great in that. So the problem is in Firefox only and the problem is in both android mobile and desktop versions. Firefox works with the touch pad and pen on desktop. It does not work on desktop with touch (finger) input. It works poorly on android mobile with finger and pen input.

And another observation:
When I use the demo for signature pad at https://szimek.github.io/signature_pad/

You can see the problem with the code not picking up the mouse up event in Firefox. Often the first and last names will be tied together with a line. But it works better than it does in the plug in within firefox. So it appears that part of the problem is Firefox and another part is with the code in signature pad.

Hi Cravaus
Thanks for this detailed report and tests. Looks like i need (at least) to update the signature pad library in the plugin …
I’ll have a look at this Firefox/TouchEvents issue aswell.

Thanks for looking. It seems like a general problem with Firefox and the way it responds to event.preventdefault(). Others have noticed and there are some bug reports in Mozilla. But apparently there are work arounds. So that is a signature pad library issue. I am trying to figure out a better way to run those lines in the JS. But I am hitting 0 so far.

Hey there
Been quite busy lately, and i didn’t have much to work on the plugin, and won’t be able to do so for quite some time. I only updated the library to v1.5.3 in the latest plugin release (2.7). Tests i did were OK.
If you find a solution to the problem, please post it here so i can check it out later ??
Thanks
