I modified the Theme Font & Size Changer 53.0 extension on the addons.mozilla.org site to eliminate automatic expiration. The extension's developer claims that a GPL 3.0 license controls the rights to this extension; and I attempted to comply with the terms of that license, especially §5 ("Conveying Modified Source Versions"). Since the .xpi file is the only source with which I worked, I do not feel §6 ("Conveying Non-Source Forms") applies. In further compliance with GPL 3, I left Baris Derin as the developer of the extension but added my own name as a contributor.
I successfully tested the modified version in SeaMonkey 2.46 and Thunderbird 52.0.1 to the extent of installing it and using it. I make no warranty that it is error-free.
This is effectively an unsigned version and thus cannot be installed for Firefox. Thus, the "fx" has been removed from the .xpi file-name. When Mozilla finally mandates only WebExtensions to the exclusion of prior extensions, I have no plans to create a new WebExtension version. Before that dreaded time, I will update this only when needed for compatibility or new features in the expiring version.
The UUID has been changed from f69e22c7-bc50-414a-9269-0f5c344cd94c to 6e5104b6-3c42-11e7-a919-92ebcb67fe33 to reflect that this differs from the version available from Mozilla's Add-ons site. Also, the URI for finding my version has been changed to reflect this Web page that you are currently viewing.
The modified version will be identified in the Addons Manager as Theme Font & Size Changer (no expire) 53.0.
