Great Extension.

Requires third party download with manual installation

Quantumになって今見ているページを IEで開き直すものが使えなくなってしまいました。代わりを探しました。ですが、なかなか実装が難しいものばかり。このプラグインは他の同様のアドインと同様に内部クライアントのインストールが必要です。けれども他のものより短い時間でスムーズに使えるようになりました。

why need to install install.bat file?

Works only with IE button. Combination with keys and left clicks won't work. I always must first open link (from favourites) in Firefox then press IE icon to force open in IE.
I'd like to open some link directly in IE but it's impossible.

Works fine

almost good

the extension works with the directory C:\Program Files with internet explorer 64 bit

it doesn't work on the 32 bit version of internet explorer

please fix this issue only on firefox

still didn't fix the default path bug!!

this extension does not work i have installed all the necessary apps that it said to and still it does not work in Firefox 57

Even after a few updates to the native client and the extension, this doesn't do anything at all in 64-bit Firefox 57 for Windows.

It works very well!Nice job~

Works fine on Firefox 57. Installing the native client is necessary because of the WebExtension format in Firefox. It is open source so harmless. Andy Portmen is very reactive on Github.

This extension works, but I've removed it. It opens a gaping hole in Firefox's security. The new node that is installed allows virtually any program on your computer to be run. It's not limited to IE.

I couldn't get this working initially, but it turned out that I had to set the path to IE's executable manually. Even though in the add-on's settings it says that the correct path (for Windows users) is automatically set if you don't manually type in a path, for me this didn't work. I had to manually set the path as the following: -

C:\Program Files\internet explorer\iexplore.exe

Once I'd done that, it started to work just fine.

I've knocked a star off because of the issue mentioned above and because of having to install an extra process to get this to work. While I get that the latter is a limitation of Firefox's new add-ons system, it's still off-putting from a security standpoint.

Many thanks to the developer for both this add-on and the "Open in Microsoft Edge" one, which worked fine without me having to set the path manually.

Neat and precise.

NOT working in new firefox Quatim release Windows 7
