Thanks to my colleague, who went tripping around Andalusia in the south of Spain and spotted several of these fire extinguishers. Finding the Firefox alone would have been awesome, but the Unix one takes the cake. Between these and the ubiquitous “Bimbo”-brand bread (which is originally Mexican), the Spanish seem to have a knack for branding that raises some eyebrows and lifts some corners of mouths in Anglophone countries.
The FireShot add-on for Mozilla Firefox allows you to take a screen shot of either the visible area of the web page you’re viewing, or the entire page. It includes an editor to tweak the image after shooting. FireShot allows you to save the image to disk, send it by mail, open it in an external editor or just paste the shot to the clipboard.
The built-in editor is a bit too much in my opinion, weighing down the add-on, but it can be good to have in your Portable Firefox, when you don’t have your favorite image editor handy.
