Seems to work for PDF, but not Excel files. Not helpful for me. Might be for you

Ulasan ini untuk add-on (2.3.6) versi terdahulu. 

With the new update, Excel files (XLSX) are now supported. You can search and select cells directly in Thunderbird. Just like: CSV, DOCX and more.
Or open and browse HEIC images, ZIP, 7z files.
All new in Version 2.7.2
I hope you give it a second chance.
