Manual install
Install from a ZIP file
The package on this site is a ZIP archive, so it has to be loaded into your browser by hand. It takes under a minute.
- 1
Download and unzip
Unzip the file into a folder you will not delete later. The extension runs from that folder, so moving or removing it breaks the extension.
- 2
Open the extensions page
Type chrome://extensions in the address bar and press Enter. On Edge, use edge://extensions instead.
- 3
Turn on developer mode
Flip the developer mode switch in the top-right corner. Three extra buttons appear above the list.

- 4
Load the unpacked extension
Click "Load unpacked" and pick the folder you unzipped in step 1.
- 5
You are done
TranslateBuff now appears in the extensions list. Click the puzzle icon in the toolbar and pin it for quicker access.

About the "Disable developer mode extensions" prompt
Extensions loaded this way make the browser show that prompt on every start. Dismiss it — it does not affect TranslateBuff. Installing from the browser's store instead avoids the prompt entirely.
