HOW TO VIEW FIREFOX EXTENSION SOURCE CODE". The extension webpage keeps all previous versions with changes log and you can extract the extension file (*.xpi) EASILY to get the source code. I see no reason to public this extension on websites like github,... - Some websites may not work properly with this extension. They may use text node as a placeholder for other element and will break the page if we modified it. - You can use shortcut keys to quickly turn on/off and control other options, in case you encounter any problem. - Please adjust the text opacity in the options menu if you use dark mode, for better visibility. 1. Apply Bionic Reading style with adjustable strength to a webpage. - You can skip short words and short text (do no apply Bionic Reading style). - You can change the strength of bionic algorithm (more bold characters with higher value). 2. Adjustable vowels for different languages. - You can input characters that will be treated as vowels for the algorithm. For example: a á à ả ã ạ. 3. Adjustable font family, font size, font weight and font opacity. - You can adjust font's properties to read the text easier. 4. Support Unicode characters. - The extension will work correctly with unicode text, instead of skipping or catching only English vowels. - However, a combination like "a" and "`" is not the same as "à". I have no plan to support this for now, as it is rare to see on the web. 5. Apply dark mode to a webpage. - You can click on the button on the Options GUI to apply dark mode to the whole webpage. NOTICE: - Some websites may block web-fonts to load. Thus, the extension may not display the selected font correctly. In that case, the similar font family in the same group will be used. - Dark mode will not work with <iframe> elements inside the webpage. The source of <iframe> elements may be somewhere else, and not belong to the webpage that you are viewing.
