[GTALUG] PSA: FireFox updates required by March 14 or add-ons fail

This looks like it could be a problem: <https://support.mozilla.org/en-US/kb/root-certificate-expiration> A root certificate used to sign add-ons expired on March 14. If your FireFox is older than 128 (or older than ESR 115.13), add-ons will probably break. My FireFoxes are currently at 136. And I don't think that I use add-ons. So I don't expect to see this.
