our Chrome extension is not getting as much attention and installations as it should - so I've added a big "Add to Chrome" button to all the language pages on languagetool.org. Feel free to translate the button's text by adding
$addToChrome = "your translation"; to your language's
This button is only shown for Chrome. There's no button for Firefox yet, as the Firefox add-on is being featured by Mozilla and thus getting a lot of installations anyway.
