[Firefox] empty buttons in addon options

[typhoon71]

From about:addons click on uBlock properties button.

The page that opens has 2 empty buttons (no text on them): they are on the left, one up and one down.
If I click on disable they go away, if I click on enable they reappear.
The upper one opens chrome://ublock/content/dashboard.html.
The lower one opens chrome://ublock/content/devtools.html.

It's similar to #1018.

FFOX 36.0.1, uBlock 0.9.1.2 (dev package), win7 x64, italian (both OS and FFOX)
Console output (disable/enable):

Can you test with 0.9.1.2-dev.1?

[typhoon71]

Got 0.9.1.2-dev.1 from your link, it's fixed: the buttons have text on it (the correct one, checked).
Question: the 0.9.1.2 I got from the release page was somehthing different right?
Because I did test that before posting... and it didn't work.

There were no translations available for these strings in 0.9.1.2-dev.1. The translations were downloaded and included in version 0.9.1.2-dev.2.

Thanks for fixing it.
And thanks again for this addon, I really like it and the philosophy behind it.
