Great Extension.

This extension has been incredibly reliable through all my installations of Firefox, which is currently a portable cloud implementation.

Great extension, you need to install Python for it to work though. I use it to open Internet Explorer, Waterfox and videos in PotPlayer. A definite must have addon.

Excellent addon, I use with mpv (various settings like mpv.exe --ytdl-raw-options=format="bestvideo[height<=?1080]+bestaudio/best" to avoid 4K that my internet doesn't handle, mpv.exe --ytdl-raw-options=format=bestaudio for audio only),
to download videos with the help of youtube-dl and a bat file (can be done without a bat, I download both bestvideo and best),
to test pages on ESR (firefox.exe -profile "path\to\ESR\profile" -no-remote) or Chromium or Opera,
to use pre-Quantum addons like DownthemAll or HDS/HLS link detector on 56.0.2,
and more.
Very handy, highly recommended.

A suggestion:
Easy backup/restore entries option

It works well.
This extension should be renamed to something more appropriate like "Open url with..." because it can work with anything you put there not just browsers.
I use it not for browsers but to open links with MPV media player (youtube links mainly).

Merci Anonymous user 36ff4e : ça fonctionne !

そもそもchrome他のブラウザがメジャーになってもfirefoxを使い続ける理由としていた程のアドオン。
かつての使い勝手と遜色ない使い勝手なのは良い。
起動させるアプリのアイコンを自動取得する仕組みがあれば尚良いが、難しいか・・・。

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.

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

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.

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

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:

"

apps = [

'Chromium',
'chromium-browser',
'firefox',
'Firefox',

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
