Originally, ff3sudoku was a Firefox 3 add-on for playing SUDOKU. Now it also features a stand-alone application and a Google Chrome extension.The main goals of the project are:
- To play sudokus from various web pages.
- To stay simple yet powerful.
Current version: 1.1.0
ff3sudoku requires Firefox 3 or newer. Works very fine with FF3.1 betas. You can install it from https://addons.mozilla.org/en-US/firefox/addon/8036
Google Chrome Extension
Firstly, follow this post
to get the development branch of Google Chrome and to enable extensions.There is no need you make your own extension, just make sure you run Google Chrome with parameter:
Then click this link to install the ff3sudoku
extension. You will be asked whether you really want to do it. After you have installed, there will be 2 features available to you:
- A sudoku icon on your bookmark toolbar. When you click it, a new SUDOKU puzzle opens.
- When you visit http://websudoku.com/, there will be a link, in the top-left corner of the screen, which will allow you play the websudoku puzzle in ff3sudoku.
Google Chrome does not allow extensions to store any data yet. Therefore you will loose any unfinished puzzles. Pitty I cannot use Google Gears.

Looking for hosting
This video contains instructions on how to use the extension.
the installation, you can display the SUDOKU sidebar, either by
pressing Ctrl+Shift+S, or from menu View->Sidebar->Your SUDOKUs.
The sidebar contains all the SUDOKUs you have started to play and not yet finished. It also contains 2 buttons to start a new medium or hard puzzle. This part still needs some work, because the button for starting a hard puzzles often generates a medium puzzle.
The button Play! can also be middle-clicked to open the puzzle in a new tab.
The add-on can detect SUDOKUs on some web-pages. If that happens, a notification is shown.
The add-on can detect puzzles from following sites:
you know about any other it supports, please let me know. If you wish
to add support for some more, let me know as well, I will see what I
can do. Post me a note to: mailto://firstname.lastname@example.org.
the most important part. As you might have noticed, most of the web
SUDOKU engines require you click on the cell and press a key -
preferably a number. My approach is much closer to native applications.
First, choose the number you want to place, then click on cells to
place the number.
The features include:
Highlighting of the column and row under the mouse.
Highlighting of the number being placed.
Highlighting of mistakes.
Marking of the used-up numbers.
You can place/remove hints by middle-click, right-click or ctrl-click. Pick one that does not clash with your browser settings.
You can press numbers to select the number to be placed. (see known bugs)
Select an eraser by pressing a spacebar or 0.
Double-click on a cell to clear it. Double-click also selects the next number to place.
