Warning - Don't update to TB 125 as it will auto-disable this extension.

If you are surprised by this, you can patch the extension to work again (own risk).

1. Rename *.xpi file to *.zip and unzip using 7zip

2. Edit manifest.json file and set strict_max_version": "125.*" or whatever Version you have to.

3. Save manifest.json

4. Create an new Zip archive containing all files from the old archive but with the updated manifest file using 7zip.

5. Rename zip file to xpi file and manually install in TB.

If you get an error, you may have included path/folder into your zip file. Make sure the content looks the same as in the original file.

TESTED with TB 125 but as I said: Your risk.

...sooo sad, the extension isn't maintained any more.
