## Firefox (ESR, Nightly or Developer Edition)

If you are using the [Firefox Developer Edition](https://www.mozilla.org/en-US/firefox/developer/), the Keeper browser extension can be side-loaded for an indefinite period of time.

<mark style="color:red;background-color:yellow;">**Important: Remove your existing Keeper extension before installing the preview.**</mark>

**Step 1. Change security preferences**

Firefox [Extended Support Release (ESR)](https://www.mozilla.org/firefox/organizations/), Firefox [Developer Edition](https://www.mozilla.org/firefox/developer/) and [Nightly](https://nightly.mozilla.org/) versions of Firefox  allow you to override the setting to enforce the extension signing requirement, by changing the preference `xpinstall.signatures.required` to **false** in the [Firefox Configuration Editor](https://support.mozilla.org/en-US/kb/about-config-editor-firefox) (*about:config* page). To override the language pack signing requirement, you would set the preference `extensions.langpacks.signatures.required` to **false**.

**Step 2. If you already have Keeper installed,** go to Extensions and click on the ellipsis icon next to the Keeper extension and select "Remove"
