I installed the Diccionario de Español add-on but i couldnt figure out how to use that dictionary. The options in the add-ons menu is disabled for this extension. I use Firefox 2. Anyone got idea about this?

Rightclick in any textfield and choose the "Languages" submenu and choose your dictionary.

I have a bookmark that fixes a page with horizontal scroll bars:
javascript:(function(){var D=document;F(D.body);function F(n){var u,r,c,x;if(n.nodeType==3){\S{45}/);if(u>=0){r=n.splitText(u+45);n.parentNode.insertBefore(D.createElement('wbr'),r);}}else if((n.tagName!='STYLE')&&(n.tagName!='SCRIPT')){for(c=0;x=n.childNodes[c];++c){F(x);}}}D.body.innerHTML+=' ';})();

I copied the code into a "Mouse gestures" new gesture but it won't work. "An error occured in the gesture function. n has no properties" How can I get this to work as a gesture rather than a bookmark?

Solution - I made a bookmarklet and linked the "Mouse Gestures" to it (too easy). Works like charm.
In a forum with long URLS and horizontal scroll bars, I can now drag my mouse and the page fixes itself! Super.
