You know this Opera feature, Fit to width:"automatically shrinks a web page to the current width of the browser. No more scrolling to the left and right. ". I can't find something equivalent for firefox. Do you know if there is a plugin for this?
search keywords: I never use the extra search field. I just type a keyword like g for google and start adding the phrases I am looking for. Other keywords I use are gg (google.de), a (amazon) auk (amazon.co.uk), imdb (selfexplaining), dict (dict.leo.org) or w (wikipedia). Add your own.
Can you do that in FF?
