fontonic
v1.7.1

Effortlessly change the web's typography!
If you are using Brave, Microsoft Edge, Yandex, Opera or any other chromium-based browsers, download the extension from Chrome Web Store. For Android devices, use the Firefox Mobile Add-On.
Run the TypeScript compiler to generate the JavaScript files required in the manifest.json:
tsc --watch -p tsconfig.jsonThe Chrome Web Store requires you to package your extension as ZIP to submit for review. Unnecessary directories like node_modules and ts should be excluded to reduce the size footprint of the extension. The build.py automates this process.
python build.py <version_string>This saves the ZIP file to the build directory (create the directory if not already there).
