π‘οΈ How to Disable Firefox Security for XPI Installation
If Firefox blocks the .xpi installation with a warning like "Installation is disabled" or "This add-on could not be installed", follow these steps:
Method 1: Allow via Settings (Firefox ESR 115+)
- Open Firefox and type
about:configin the address bar. - Click "Accept the Risk and Continue".
- Search for
xpinstall.signatures.required. - Double-click the preference to set it to
false. - Restart Firefox.
- Drag and drop the
.xpifile again β it should now install.
Method 2: Add to Allowed Sites
- Open Firefox Settings β Privacy & Security.
- Scroll to the "Permissions" section.
- Next to "Install Add-ons", click "Settings".
- Add the website where you downloaded the
.xpifile (e.g.,https://github.com) to the allowed list. - Click "Save Changes".
- Try installing the
.xpiagain.
Method 3: Install via about:debugging (No Security Bypass)
- Open Firefox and type
about:debuggingin the address bar. - Click "This Firefox".
- Click "Load Temporary Add-on".
- Select the
manifest.jsonfile from the extracted.ziparchive. - The extension will load temporarily (remains until Firefox restarts).
