Please, update the extension to the latest version of Firefox!

Good Extention.
Some wish from me:
Is it possible to add "open with" to the context menu not only for the links on the page, but also for the bookmarks in the bookmarks menu too?

Still the best "open with" addon out there. Thanks a lot!

非常好用！

I love this

Many thanks for this great work !! ;-) Maybe hard to install for some people, but I think the documentation is good enough and this work really great with all browsers....

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
