Look what you have done FireFox turned a once great simple addon into a complex addon.

6.8.6 version took some hacks for Basilisk.
I've got the toolbar button working on my Basilisk install matching the one on my Pale Moon install. Took some slight modifications of about-openwith.js, openwith.js, and openwith-fx.xul

It is cool seeing Pale Moon icon in my Basilisk and Basilisk icon in my Pale Moon status bars.
Also convenient for checking how sites render in IE, Edge, FF, Chrome easily.

I prefer the 6.8.6 version on my browsers which will continue to support XUL addons.

It may not be the developer's fault that he had to modify this extension like this, but now it is useless because too complicated to install. You have to understand what Python is and how to install it (on a Mac). I tried it several times and couldn't.

I thought the instructions were fairly simple. Install python. Open a command prompt and run the Python script. Great extension, very very useful.

Instruction for installation is insufficient, only thanks to user f495dc (not far below) i managed to install this app

i repeat it again here

1. Install Python (Download from link, run file, and then follow install screens)
2. Download the linked .py file and then move it to a special folder or the root of your C:/ drive (I put mine under the python install folder/Lib)
3. Open a Windows Command prompt (Type command or cmd into Start Menu search and select the cmd.exe)
4. Navigate inside the command prompt to the folder where you put the file in #2 (i.e. "cd c:\path_of_file_folder")
5. Run the command given in instructions: "open_with_windows.py install" (You must be in the same folder as the file)
6. Click Test in the extension info screen inside of Firefox. It will tell you immediately if it worked and you can begin finding/adding external programs to launch

It was good before, but the new install process with Python is complicated and I couldn't get it to work. :(

Followed the directions for Firefox 57. Doesn't work. I keep getting "open_with_windows.py is not recognized as an internal or external command, operable program or batch file." Lame.

It works well, you have to manually paste the path to your exe

Love the extension in Thunderbird but it is difficult to locate

Perfect for opening video links with mpv. It just works.

Edit: Contrary to recent reviews, as of March 2024, this add-on still works! At least on my machine (Windows 10).

Loved this extension for such a long time and now on Firefox 57 is fantastic. Even better, developer Geoff has the support of his work that other developers should aspire to. Thank you.

simple to use and reliable

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!

I spent so long looking for an extension that does this. I want the author to know how much I appreciate any work he puts into this (already donated

I missing Qupzilla.
Your script cannot find QupZilla

I have modify it in this way:

"
def find_browsers():
apps = [
'Chrome',
'Chromium',
'chromium-browser',
'firefox',
'Firefox',
'Google Chrome',
'google-chrome',
'opera',
'Opera',
'qupzilla',
'QupZilla',
'SeaMonkey',
'seamonkey',
]
"

INSTRUCTIONS ON HOW TO INSTALL IN WINDOWS BELOW

So far this is working fine with Windows 8.1 - I will report back if I have any issues in 7 or 10 when I get around to installing it on my other systems.

For those not understanding WHY this new setup is required, Firefox has completely changed how extensions will work moving forward. Long story short, they took away the deep functionality which pretty much all developers relied on. Trust me, no one is happy about it and the majority of devs are publicly jumping ship.

However, I'm not sure of the issue from reviewers about installing Python for this extension to work, since all it does is expand a few language extensions in the background on your computer. Python has been around since 1991 and trustworthy. A standard user will never see a difference in any normal day to day operations.

For those who do not understand how to install in Windows:
1. Install Python (Download from link, run file, and then follow install screens)
2. Download the linked .py file and then move it to a special folder or the root of your C:/ drive (I put mine under the python install folder/Lib)
3. Open a Windows Command prompt (Type command or cmd into Start Menu search and select the cmd.exe)
4. Navigate inside the command prompt to the folder where you put the file in #2 (i.e. "cd c:\path_of_file_folder")
5. Run the command given in instructions: "open_with_windows.py install" (You must be in the same folder as the file)
6. Click Test in the extension info screen inside of Firefox. It will tell you immediately if it worked and you can begin finding/adding external programs to launch

Can't get it to work with Python and all the other steps involved.
