I found the extension great, but I can't install the script.
I type the path in cmd with the script name and then install, but cmd keeps telling me to type install.

C:\Users\User\AppData\Local\Programs\Python\Python310>open_with_windows.py install
This is the Open With native helper, version 7.2.6.
Run this script again with the word "install" after the file name to install.

I have no idea where the error is.

This extension is absolutely amazing. I consider it one of the very select "Absolutely Mandatory and Indispensable" extensions I always use. I truly do not know how I lived without it, before first finding it. I don't know why Mozilla isn't pushing this as one of the *Recommended* extensions, because it should. Maybe I'm overestimating the number of people who would be interested in launching a webpage from one browser directly into a specific other browser, but for those that ever do this more than occasionally, this thing is terrific. I love Open With so much.

A little messy to install, but very useful when you get it going.

Works perfectly on Manjaro Linux! The AMO page should mention that the extension requires additional setup after installation. It took me a while to figure out that I need to go to the Options page after installing the extension.

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.

(1) In C:\Users\xxx\AppData\Local\Programs\Python3xx paste the file: open_with_windows.py
(2) open prompt command here > paste this in cmd open_with_windows.py install
(3) everything will be ok, if 5 files appear:
open_with bat
open_with_chrome
open_with_chromium
open_with_firefox
open_with_thunderbird

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.
