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.

Thanks! Working perfect with my Ubuntu machine!

I don't know what happened to all the old "open in" or "open with" extensions that used to work perfectly. Now all the extensions need an add-on program installed. I added Python but it still doesn't work. I have no idea how to do the "install" command. So this is basically worthless. Could we get some more detailed instructions? Or just make it simpler for all us non-geeks?

Not usable until a new solution is offered.

First broken through requiring me to install something new software for a *plugin* to work, then also broken because not compatible with ESR.

Loaded Python, tried several versions, and no connection to IE could be made. Does not work on windows 10 machines-7 is anotherstory.

The update requires python instal???? Sorr but most people will never install that to use a plugin.

Firefox57 kills it, even Python script install on windows does not work, "see browser console" -> where should you find this? Conclusion : too complicated for the average user.

Works fine, lightweight open source .py helper file,* option to select all installed browsers, good job.

* with FF 57, all other "open with" addons require external helper files, too, one of them is 20 MB on Linux... However, the Python helper file has to be installed using the command line, which may be difficult for some users.

Have successfully transitioned to the new version with the external Python helper application (on ubuntu, a version of python was already previously installed). For the previous version, I had "browsers" (actually custom scripts) specified by command line, and the UI for the new version made it relatively painless to re-create them. The biggest frustration was that browsers configured under the old version aren't automatically imported into the new version upon upgrade - and in my first attempt to set a browser up, I got my entry for the "name" and the "command" field the wrong way round - but after correcting that mistake, it worked first time.
