A little touchy to install it for a newbie like me...
But once you follow the instructions given, it work like a charm!
Thanks a lot from a Waterfox Classic user.

AWESOME! I wanted such an extension for a long time! The best part? It supports Linux, unlike some other similar extensions! :D
This extension has a HUGE potential! I just added SMPlayer to watch YT vids in it and damn - it works! :D :D

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.)

Thank you for a very nice add-on.
I have one request, but I want you to be able to export the settings

不能直接运行，需要装Python，并且还要在系统中建立一个文件。太Low了。

La verdad es fácil la instalación y funciona correctamente. sería bueno que estuviera para los demás exploradores.

Does not work in Quantum: instructions are poor and following a tutorial for installing the two additional files still results in failure. Sorry.

Nécessite Python, pas facile à installer avec Windows, Surtout un Windows 7 !

Excellent add-on. Installation requires a few extra steps, but the instructions are very clear. Deserves donations.

I kept checking back to the reviews in hopes of more info on the installation of "open with", and there it was. I put open_with_windows.py in my Windows\system32......opened a command prompt, which opened in the Windows\system32 folder, and ran the open_with_windows.py install, and that was it for me. I ran test installation in my Browser and Thunderbird, and it showed, "Found version 7.2.3 at C:\​Windows\​System32\​open_with_windows.py." I then edited the order of my four Browsers, with Firefox on top.
Thanks to all the reviews with the help, and thanks to the the Author of this addon!!

Amazing addon! I'm only missing the ability to select multiple tabs and open them on the chosen browser, instead of doing it manually for each tab! There's an open issue on the github repo asking for this already, just in case other users would like to show their interest on this feature.

Misleading description, This extension can also launch different application and media player . Superb

安装了python，还是不能打开

Sorry, this add-on has served me well in the past, but now it completely stopped working on Firefox (clicking the browser icons does nothing, and sometimes it the menu also displays the message "Open With can't connect to the outside world"). I of course would prefer to get support fixing this rather than leaving a low rating, but there doesn't seem to be any realistic way to request help.
