Please let us know when we can expect and update on this extension. It is a bit frustrating having to click on every message to enlarge.

I thank you in advance.

This review is for a previous version of the add-on (1.0.8).  This user has a previous review of this add-on.

Set minimum font size in message view

In addition to the font size settings in Preferences->View and Preferences->Display, you can use a userContent.css file in the "/chrome" sub-folder of the user profile and add the following CSS value "body { font-size: 20px !important; }" to the file (without quotes) to store a minimum font size value between sessions. Since this file isn't automatically created or managed by any built-in functionality, it's beyond the scope of my addon to build something from scratch.
