You can use local AI beside a Firefox page. The Off Grid AI extension opens a sidebar and sends your question to OGAD (Off Grid AI Desktop). The desktop app owns the models and does the processing. Firefox provides the page and the place to read the answer.

Install OGAD, download a local text model, and activate it. Keep OGAD running during browser chat. The default connection is the desktop gateway on the same computer at http://127.0.0.1:7878/v1.
The extension setup here uses a source build. It is not an AMO store installation. You need Node.js 20 or later and internet to download source and dependencies. The Firefox temporary add-on is removed when Firefox restarts, so keep the built folder available to load it again.
git clone https://github.com/off-grid-ai/browser-extension.git
cd browser-extension
git checkout 970fec49e2a630a3e1f419c1fc86df241891d40c
npm install
npm run build:firefox

The pinned extension source supplies this build. the Chrome folder is not the Firefox setup.
Open a long product or documentation page and turn Use page on. Ask for a result that helps with your next decision:
List the required setup steps on this page in their stated order. Keep warnings beside the step they affect. Do not add steps from memory.
The extension extracts readable text from the current page. Check the answer against the page before following it. Hidden controls, a login state, and incomplete can affect what the model receives.
For a policy page, change the question:
What does this page say about cancellation? Separate the deadline, any fee, and exceptions. Quote only the short wording needed to identify each condition.
This gives you a list to verify instead of a general summary. If the page does not state a fee, the answer should identify that gap. A local model can still make a wrong inference.
Basic model access and approved desktop access are separate. Pair when you want shared chats or desktop tools. In extension Settings > Desktop, select Pair with desktop. Compare the six words with OGAD's native dialog and approve there only when they match.
For the first Firefox setup, prove ordinary chat before adding these workflows. The repository notes that browser origin handling can affect pairing. If chat works but pairing fails, retain that distinction when reporting the problem. It is not proof that local model inference failed.
Chrome's debugger-based task route does not apply unchanged to Firefox. This guide covers sidebar chat and page questions. Do not assume that every automated browser action behaves the same across the two browsers.
After restarting Firefox, load the temporary add-on again. If the sidebar is present but no model is listed, check OGAD and its active model. If the reply stops partway through, check the desktop connection before repeating the request.
Keep a source link and any checked notes you need for later work. Local inference avoids a hosted AI service for this selected route; it does not remove Firefox's website traffic or the need to protect saved browser data.
This guide covers OGAD beta 0.0.55-beta.114. The release and build record identify the desktop version and its included Pro code. Setup details follow that code; they are not a device test.
Download OGAD and load the Firefox build. Start with one question about a page you know, then check the answer beside its source.
