Have you tried staying logged in on a separate unmodified browser? Sometimes my extensions have weird side effects

This is not the issue; and this test was already performed well in advance of the posting of this post. I am aware of every plugin I use and have a general idea about how it interacts with my browsing…not to mention several other browsers I can spin up with varying levels and degrees of plugins and protections to troubleshoot the issue.

Currently I am on Firefox 129.0; and have tested the following and observed the same behaviors:

• Librewolf
• Ungoogled Chromium
• Edge
