Download & install MUFFLER
Chrome Web Store approval is still pending.
Until that lands, you can download the private build here and install it yourself in about 60 seconds.
Download muffler.zipUnzip it somewhere easy to find - you'll need the folder in the next steps.
Open a new tab and go to chrome://extensions
Find the Developer mode toggle in the top-right corner and flip it on.
Click Load unpacked - a file picker will appear.
Navigate to the folder you unzipped earlier and select it. MUFFLER will appear in your extensions list.
Click the puzzle-piece icon in the toolbar, then click the pin next to MUFFLER.
Keep the folder in place. Chrome loads the extension directly from the folder - if you move or delete it later, MUFFLER will stop working.
