Status: RESOLVED DUPLICATE of bug 810796

(Core :: Layout: Form Controls, defect)

Description

[Daniel Holbert [:dholbert]]

Noticed this go by in my logcat output on my B2G trunk build (but I suspect it affects desktop builds as well):

JavaScript Warning: "Found trailing token after pseudo-element, which must be the last part of a selector:  '['.  Ruleset ignored due to bad selector." {file: "resource://gre-resources/forms.css" line: 90}

Looks like this is for line 90 layout/style/forms.css , shown here:
> 89   input.uri-element-right-align:-moz-locale-dir(rtl) > .anonymous-div[dir=ltr],
> 90   input.uri-element-right-align:-moz-locale-dir(rtl)::-moz-placeholder[dir=ltr] {
> 91     text-align: left !important;
> 92   }

Apparently the "::-moz-placeholder" has to go at the end there.  This was added a few days ago in bug 737786.
