I've called the big guys to help you. Good luck.

What job does your app do? Any other problems / issues?

Do you have a link to a publicly available page or test case demonstrating the problem? (I could only test on Windows myself.)

Hi, there. I tried to make a simple sample case... but it worked. My application is a backbone based dashboard panel. The problem occurs in some special condition I am trying to replicate. I the following links it was related to jquery.ui.modal window and datepickers. It is not my case, but I guess I am using something similar to modal windows.

I guess to case are related: 1. Select does not open dropdown onclick 2. Month select in datepicker inside a bootstrap-modal won't work in Firefox

If I succeed replicating the case, I will post it here.

Thanks!

Got it!

I was using the jquery-ui's deprecated function .disableSelection() . It should disallow users to select text, but seems to give this collateral effect on FF.

I will try a CSS alternative suggested here .

Thanks!

Anyway, the FF behaviour is not fine. Disabling text selection should not disable the dropdowns...

Hi floridia, if you compare the CSS in Firefox's Inspector between your two versions, what rules are being used to disable selection? Some of the proprietary -moz properties can definitely cause problems.

Hi jscher2000,

It seems it works by capturing the event and dropping it out...

From jquery-ui core:

(...) disableSelection: function() { return this.bind( ( $.support.selectstart ? "selectstart" : "mousedown" )

Could it be because there is no "selectstart" event, so it uses the "mousedown" instead ?

I didn't find that CSS rules in the inspector...

According to this site , FF and Opera don't have the selectstart event...

I think that's right.
