Using a userscript manager: install a compatible manager first. Choose your browser above, select Install AIOEXT, and confirm the install in your manager. If the installer doesn’t open, download the script and import it into the manager. Chromium managers may also need their user-script permission enabled.
Using the Extension ZIP: download and extract the ZIP. Open your browser’s extensions page, enable Developer mode, then choose Load unpacked and select the extracted extension folder.
Firefox and Safari: use a compatible userscript manager. The ZIP option above is for Chrome, Edge, Brave, and Opera; permanent Firefox and Safari add-ons require their own signed releases.
Hello Kitty browser colors in Firefox (Beta): native tab and toolbar colors require the Firefox extension source package below. The userscript still supports matching AIOEXT appearance, but cannot change Firefox’s native theme.
For a temporary local installation, extract the source ZIP, open about:debugging#/runtime/this-firefox, choose Load Temporary Add-on, and select its manifest.json. This unsigned installation ends when Firefox restarts. A permanent signed release is not included. In AIOEXT, open Hello Kitty appearance → Browser colors, then choose Enable Hello Kitty to allow the optional permission. Restore browser appearance turns it off.

Tor Browser: extra extensions can reduce anonymity. AIOEXT uses the Firefox userscript path, but isn’t recommended for browsing where anonymity is essential.
