fiddle code: http://jsfiddle.net/2jzmr/1/

update: saw problem not version of firefox, tested on 2 different computers same version of firefox (v28) , 1 worked , other did not. i've reinstalled firefox on machine , problem persists. tested on firefox in android 4.4.2 , worked normally.

update2: when open firefox in security mode error not happen. disable plugins, add-ons , themes not correct error.

update3: found reason of error. problem firefox hardware acceleration.

i follow steps:

  1. at top of firefox window, click on firefox button , select options
  2. select advanced panel , general tab.
  3. uncheck use hardware acceleration when available.
  4. at top of firefox window, click on firefox button , select exit
  5. start firefox way do.

but possible change css or perform code via javascript run in firefox hardware acceleration turned on?

the alternative follow if not, use images instead of css3.

edit: firefox @ version 32.0 , problem continues.

i don't problem on ff, can try double ':' before pseudo-element :

sometimes see double colons (::) instead of 1 (:). part of css3 , attempt distinguish between pseudo-classes , pseudo-elements. browsers support both values.

note: ::selection starts double colons (::). can use 1 pseudo-element in selector. must appear after simple selectors in statement.
