1465743 - On mobile it's difficult to click on the top left button on herschel.eu

Status: RESOLVED FIXED

(Core :: DOM: UI Events & Focus Handling, enhancement, P3)

Description

[Julien Wajsberg [:julienw]]

STR:
1. Go to herschel.eu. (if you get a popup asking to change the website, click on "continue on this website")
2. Try to tap on the top left menu button.

=> Its much more difficult to activate than in Chrome.

This is a small <a> button with a JS click event attached to it. There seems to be several issues:
- we need to tap right on top of it
- even when we tap right on top of it it doesn't seem to activate all the time.

I feel like kats might have salient thoughts on touch "fuzziness" but I could be way off.

Does it behave better if you turn on ui.mouse.radius.enabled in about:config?

Comment 3

[Julien Wajsberg [:julienw]]

actually herschel.eu changed their website so I can't try, and their new website reacts better even without the fuzziness.

I tried on other places where I had similar difficulties:
* twitter.com, dismissing images: looks like they changed too and this is better now, without the config
* lemonde.fr, displaying the top left menu: this is better with this pref.

I'm a bit surprised it's not enabled in Firefox yet, given how much thought and polish we injected into this for Firefox OS.

I'll continue looking for other use cases, I can update here or file new bugs if I find more, as you prefer.

Yeah, I find the behaviour much better with that pref on, but there were some other issues with it, and it was disabled in bug 1247095.

You can put them here, that's fine.

Per comment 3, herschel.eu has changed their website and this bug no longer reproduces. I turned on mouse event retargeting in bug 1618532 which would have fixed it. At any rate, we can close this bug I think.
