The analysis part of the tool seems to do nothing. Well, the rest of it doesn't respond either.

First I installed jsdetox in my OSX and when I saw that I thought it was the OS, even though there were no errors. So I installed it in my Debian and the same.

I don't see errors anywhere:

I've been stripping down the code to easier and easier bits just to try. I even tried the sample on your website: var x = 10 * 3 + 100 - 70 / 10; but this is all i get:

It was weird the disparity between what I saw in Chrome and back in the server so I dug a little more. Using a requester app I found I could get the backend to do the analysis so it was something in the frontend.

Long story short, one ad blocking extension in my browser was blocking my requests. I filtered the site and It's working now! 😁

Thanks for analyzing this and documenting it here, this might help other people having similar issues. Great to hear it works now for you!

Thank you for developing the app. It's a shame that it hasn't been updated/improved in so many years, though. There are plenty of nice features and improvements that could be added. If I knew ruby I'd help out (or if it had been written in js or c/c++ 😜)
