Review for SendWithoutSubject by DS
Rated 5 out of 5 stars
This addon is fully functional in TB 60 by bumping the maxVersion or setting "extensions.strictCompatibility" to "false" in about:config.
To change the maxVersion, follow these instructions:
------------------------------
1. Unzip the .xpi file (change extension to .zip to extract natively, or use 7-Zip or other extractor).
2. In extracted root folder, open "install.rdf" file in a text editor.
3. Search for "<em:maxVersion>" string, and change the version number to "60.*" (no quotes).
4. Save file.
5. ZIP up addon, keeping complete folder structure. Change .zip extension to .xpi.
6. Install in TB 60.
