Preliminary Checks

• I have read and understood the important section above.
• I have searched existing issues and avoided creating duplicates.
• I am not filing an enhancement request.
• I have checked that this issue cannot be reproduced on Mozilla Firefox.
• I have checked that this issue can be reproduced once I removed all my Mods and Custom CSS.

What happened?

Zens current release appears to lag behind Firefox upstream version (Firefox 150) which includes many security fixes: https://www.mozilla.org/en-US/security/advisories/mfsa2026-30/

The README.md states that the releases are built on firefox 150 - which seems "not true" as the latest release is two weeks old according to the github release page.

My installed flatpack version (1.19.8b (Firefox 149.0.2)) of zen as well as the downloaded tar.xz (1.19.8b (Firefox 149.0.2) (64-bit)) show that they are still not up to date.

Expected behavior

Zen reports to be based on Firefox 150

Actual behavior

Zen reports to be based on Firefox 149.0.2

Steps to reproduce

Check out release section on github page.

Hi, the update should drop soon, it says on our docs updates are within 0-72 hours. There has been some breaking stuff regarding update signatures that prevented us from releasing yesterday.
