Used to be one of my favorite addons. Did not use it for a long time.

V 7.1 (Python 2.7) stopped working after upgrade to Firefox 100.0.2 from 99.0.b8.

"Something went wrong. There might be more information in the Browser Console.."

Any ideas?

Useful to run commands like mpv or yt-dlp. I've quickly reviewed parts of the source code, looks fine.

For the above commands, best practice is to add "--" as the last argument. (Maybe not a real concern, because the URL is passed as a single argument and probably cannot start with "-", but just in case.)

(Update 2023-12: Keeps working for me, for years, without maintenance.

Intitial setup was a hassle, but it's much easier than when I wrote my own private extension for the same purpose. Firefox keeps deactivating that one all the time, because apparently I shouldn't trust my own code, lol.)

Finally, the installation is successful,Set the default open mode to Python,and use "open_with_windows.py install"
in the folder where the file is located. If you open any other windows when use "open_with_windows.py install" ,you should set the default open mode of .py file. Chinglish

Thanks for the Plugin! Good but complicated. Have written a small tutorial in english and german. Maybe it helps someone.

Great add-on, but open with Edge doesn't work.

Would be nice if it works with bookmarks too.

Works great, and the Python Script is much better than the binaries required by other tools. That said, I'd prefer a solution without additional install, but that unfortunately doesn't seem to be possible with the new add-on framework :/

I suppose that it comes down to this: is installing python a pain in the ass? If you think so, avoid this extension. Otherwise, this extension is great!
