question re. add-on's URL setting option
Question on the Extensions setting page (menu: Opera/Extensions). Several extensions have this option:
Allow access to file URLs
What files would be accessed & how does functionality change if this option is selected?
(I tried to search for this topic, but couldn't get a combination of key words leading to answer)
With the PDF.JS extension, that means you permits the extension to open an pdf file that is stored in your computer
It's this permission: http://dev.opera.com/extensions/tut_match_patterns.html
Thanks for_d! Your comment plus the included link defining 'Content scripts' makes it very clear.
