I'm a big user of Firefox's tab groups (typically with 100s of tabs between the groups) and this is definitely not the case. I just tried it out and closing the last tab in the current group will take you back to the group overview screen.

I'm just starting out on something similar (OCR'ing letters from a word game), so would also love to here more about the process you're using with Tesseract and OpenCV.
