How many times have you thought of making change to online content on some website and taking a screenshot or print out. Well, this is not possible since the content we see is read only and is hosted on third party servers. We have a free bookmarklet ( a script bookmark ) which can give you temporary write access on the local copy and allows you to make changes and can printout.
The modified web page stay until you refresh. The feature is very useful if you are printing web pages or even for making fake screenshots.
Just drag & drop this Bookmarklet: Edit current website on your browser.
