Sourcegraph for Firefox by Sourcegraph

The open-source Sourcegraph extension adds code navigation and code intelligence to GitHub, GitHub Enterprise, GitLab, Bitbucket Server, and Phabricator.

• Code intelligence on your code host:
* Hover tooltips with documentation and type information
* Go to definition
* Find references

• Integrations with third-party services like Codecov coverage overlays, open-in-editor buttons and many more with Sourcegraph extensions

• Browser shortcut (src + Space) that performs the search on your Sourcegraph instance

It works for 20+ languages on public and private code on popular code hosts (see below).

Make it work on your code host:

• GitHub - No action required. Your extension works here by default.
• GitHub Enterprise, GitLab, Bitbucket Server and Phabricator - grant additional permissions in the extension menu

Browser extension docs: https://docs.sourcegraph.com/integration/browser_extension

Make it work for private code:

To use the browser extension with your private repositories, you need to set up a private Sourcegraph instance and connect it to the extension.
