This browser extension checks if it's friday
The extension add a new button to the browser. When you want to know if it's friday, click on the button.
- From the top bar open Window.
- Click on Extensions.
- Click on Load unpacked.
- Select the extension folder
To open the settings type this in address bar:
about:debugging
- Click This "This Firefox".
- Load Temporary Add-on...
- Select the manifest.json
Unfortunately, Firefox only supports loading the extension temporarily. This means you have to load it every time you close your browser.
To load the plugin permanent it is requried to have the plugin package, signed and reviewd by Firefox. I did not bother jumping trough the hoops of get a developer account and go through their review process.
Nice to know details for any future development.
