Efficient and lightweight but with a difficult UI Rated 3 out of 5 stars

This tool is super fast and lightweight but it has some weaknesses in the UI.

The ffscrape UI opens inside the browser window but closes whenever you switch tabs, causing your changes to be lost. If like me you are using firebug to probe the DOM while writing the selectors it becomes quite difficult to open and load ffscrap each time you switch window/tab. I ended up working in a text editor and copied the final JSON into ffscrap when it was finished.

Also the normalizeNumber pre-process, which is a great idea for cleaning $-symbols and what not, also cleanses - (minus) symbols causing all the negative numbers to become positive.

Once I had worked out the nuances however, I found the scraping process to be very quick and efficient so I think the underlying framework of this addon is sound and I'd still recommend it.

I would love the UI to keep its simplicity but open in a separate window so you can use it in conjunction with firebug/dev tools :)

This review is for a previous version of the add-on (0.1.2.1-signed). 

To Tab button

There is "To Tab" button, by which you can open scraper definition UI in new tab (must give it name before). Then scaper works on tab left from its tab.

The developer didn't give any instructions or say what kind of script. Out of curiosity I tried it anyway. I right clicked on some tables and couldn't find a context sensitive menu. I didn't notice anything new in the menu bar or in the browser chrome. I don't see where it is, how to activate it, so I can't even guess as how to script or target anything.

This review is for a previous version of the add-on (0.1.1.1.1-signed). 

Short instructions

Instrucktions are at plugin home page.
Quickly:
Plugin sit in Add-On Toolbar - so first you should show display it View / ToolsBars / Add-on Toolbar. There is plugin icon - right click on it and you can define script for that page - there is example how it should look like - it's basically JSON which defines CSS selectors to choose right data.
