Install VRT on Firefox

Firefox has a different extension system than Chrome/Edge, but the install is still straightforward. Takes about 2 minutes.

Note: Firefox treats unsigned extensions as "temporary"—they'll be removed when you close Firefox. This is a Firefox security feature. For a permanent install, we recommend using Chrome or Edge, or waiting for our official Firefox Add-on Store release.

Download VRT

Click the button below to download the VRT extension package. It's a .zip file—don't open it yet.

Download for Firefox

Extract the Folder

Find the downloaded .zip file and extract it. You'll get a folder called something like vrt-firefox.

Important: Remember where you put this folder—you'll need to navigate to it in a moment.

Open Firefox Debugging

Type this into your Firefox address bar and hit Enter:

about:debugging#/runtime/this-firefox

This opens Firefox's debugging page where you can load temporary extensions.

Load Temporary Add-on

Click the Load Temporary Add-on... button. Navigate to the folder you extracted and select the manifest.json file inside it.

Firefox difference: Unlike Chrome/Edge, Firefox wants you to select the manifest.json file, not the folder.

You're Done (For Now)

VRT should now appear in your browser toolbar. Open ChatGPT, Claude, or Gemini—VRT will automatically detect your conversations and let you export them.

Remember: This is a temporary install. When you close Firefox completely, you'll need to load the extension again using Step 3 and 4. We're working on getting VRT approved in the Firefox Add-on Store for a permanent install.

Troubleshooting

"This add-on could not be installed because it has not been verified"

Make sure you're using about:debugging to load the extension, not dragging it into Firefox or using about:addons. The debugging page allows unsigned extensions.

Extension disappeared after closing Firefox

This is expected behavior. Firefox treats manually-loaded extensions as temporary. You'll need to reload it each time you restart Firefox. For a permanent solution, use Chrome/Edge or wait for our Firefox Add-on Store approval.

VRT doesn't detect my conversations

Make sure you're on a supported site (ChatGPT, Claude, or Gemini). Try refreshing the page. If it still doesn't work, reach out to support.

Want a permanent install?

We recommend using Chrome or Edge for now—their manual installs persist across browser restarts. We're working on getting VRT approved in the Firefox Add-on Store.
