RUN THIS SCRIPT AT YOUR OWN RISK

This is for addons signature expiry of firefox in 2025-03-15. Not recommended unless you understand the security risks.

If you are not running Firefox ESR with xpinstall.signatures.required set to false i.e. normal firefox, then you have some steps to follow first to tweak your firefox, your OS's methods may vary:

This script is to be run in firefox developer console.

Works for some newer version (2024+) of firefox, so you may have to tweak as needed for your firefox version e.g. ChromeUtils to Components.

• may need to run special developer console Ctrl-Shift-J
• may need to set devtools.chrome.enabled to true in about:config

unsigned addons 24 hours validity due to automatic re-verify

Addons may be automaticallly re-verified and re-disabled due to default timer of 24 hours set in the settings.

You may want to find const XPI_SIGNATURE_CHECK_PERIOD = 24 * 60 * 60; in omni.ja's ./modules/addons/XPIProvider.jsm to edit accordingly.

You may also want to look at verifySignatures() in omni.ja's ./modules/addons/XPIPDatabase.jsm

You may need to find the files in other locations in different version of firefox.

Some users reported that in certain firefox versions, the edits to omni.ja doesn't work, as there's a precompiled version somewhere.
