This is a simple web extension for Firefox browsers that hides tweets from verified accounts on Twitter.
If there are verified users that you don't wish to hide, you can manually enter their handle in the excludedAccounts variable.
All you really need from this repo are the contents of the src directory. As long as you save those 2 files together (content_script.js and manifest.json) and inside their own directory, this should work as expected.
Load this extension into Firefox by navigating to about:debugging in the address bar, clicking "This Firefox" on the left-hand side, clicking "Load Temporary Add-on", and selecting the manifest.json file.
Open Chrome and navigate to the Extensions page by clicking the three-dot menu icon in the top right corner of the browser and selecting "More tools" > "Extensions." Alternatively, you can navigate to chrome://extensions/ in the address bar. Then, toggle on the "Developer mode" switch and click the "Load unpacked" button. Select the folder containing the extension files.
