Nasty fix for Firefox OS X not working

[silviomoreto]

The new version of firefox for mac osx supports the os scroll bar, so this workaround c2be16e does not work any more.

I am trying to fix this, but if someone already has a fix, please share.

It still seems to work for me in FF 31 on OS X. In what way does it seem broken in your tests?

The new version of firefox is using the scroll bar from the OS if you are using magic mouse, so the 17 pixels are changing the div width.

To try to solve this I changed this value to 0 pixels. But both scroll bars appear one over the other. I dont know if there would be another way to fix it since ff does not support scroll bar width.

I'm also seeing that this workaround is broken on OS X (FF 31). The width of .tse-scroll-content is 17px too wide as a result of the hard-coded magic number. Removing the workaround solves the problem (though this does result in double-scrollbars, one on top of the other).

I'm not sure what the best solution is as I haven't experienced first-hand the issue that prompted the workaround in the first place.

The plugin attempts to emulate the OS X scrollbar -- so it should only target other platforms, right? This would avoid the need for workarounds like this one. It looks like OS X can be sniffed using something like navigator.appVersion.indexOf("Mac") != -1

I kind of disagree @6twenty . I use OS X but with a pen tablet, not the mouse. So my scroll bar is not like the one emulated by the plugin. This can happen for someone that is not using magic mouse as well.

I don't follow, @silviomoreto - how does using a different device change the scroll bar? The OS renders the scrollbar, so what gets rendered is the same whether you use a magic mouse or not.

On OS X there is also a setting to always show scrollbars, which displays a permanent scrollbar similar to Windows, so disabling the plugin based on platform isn't an option.

What might be an option is detecting a zero width scrollbar, which would indicate that user is on OS X and has has the scrollbar set to show automatically (which is what the plugin emulates), and disabling the plugin in that circumstance only. That's kind of a bigger conceptual decision though.

In the shorter term I will revisit the FF fix and see what I can do to hide the OS scrollbar without needing to make the content wider, since obviously it's undesirable for the content to be cropped. I might not get to this for a while though, since I'm super busy at work for the next couple of weeks.
