Requires an extra utility that is NO LONGER AVAILABLE.
Garbage. I'm using it under Xunbuntu and it does nothing. The path works in a shell, but the button does nothing.
Does not work. No error message to indicate why it does not work.
Didn't work. Win10, latest FF and Chrome.
I have chrome book and this is supposedly easy to download but then there is a bunch of stuff to do after that. I'm pretty confident it would work but I'm having difficulties
Doesn't work, don't waste your time on it.
Does not work. First, you need to know how to use the command line interface on Mac just to install it. I know how to do CLI on Mac. I successfully run the install command from the proper directory on the Mac (which requires administrative privileges), but the Terminal CLI reported "command not found". The instructions say Python is required. I have several versions of it installed, including Python3. This extension is not recommended for being DOA.
it does not work
Doesnt work
Needs extra software, but the download page contains only one download button, and that button downloads some sketchy program with a TON of bloatware. Avoid at all costs.
sorry. doesn't work. wasted time. (archlinux/python2.7/chromium)
does not work closes tab but does not open it in FF (win7x64)
it doesn't work
Like the other extension, this one requires an additional installation because Chrome doesn't allow opening other browsers directly. Fine. You have to 'install' a python --YECHHH!-- script, which is always problematic, from the command line. Worse, I only got it to open one tab in FF. It didn't work on any other tabs. And now it doesn't work at all. Worst of all, there is no uninstall script for the script I installed.

Does not work at all.
installed host, installed python, restarted everything. doesn't work. period.
The extension worked well for me with Win 8 and Win 10 and was very useful. But it doesn't work anymore on both Win (8 & 10), possibly since Mozilla updated Firefox to Quantum. Posted the following question to support: Could you confirm that the Extension is not working with Quantum? If yes, do you plan a fix? Thank's a lot in advance for your reply. I downgrade from five to one star, as the extension is not working actually, will upgrade stars again as soon as the extension works again. Previous opinion (29.10.2015): Works perfectly with Windows 8, very useful extension. Thanks! To work Windows host needs to be installed from Developers website: http://openwithfirefox.wix.com/openwithfirefox (very easy to install).
stopped working.
Waste of time
Doesn't work
does nothing
It is not working for me.
FYI: Does not work in 64-bit version of Chrome. 64-bit will not accept NPAPI plugins.
No Context menu item, which makes it useless

Didn't work for me under Arch linux. Input the executable path but was unable to get it to work.
don't work on ubuntu 14.04
Does not work in Linux.
All it does is start up firefox, I can do that without this
Needs Mac compatibility
doesnt work at least for me
It doesn't work! When I go into Linux, then penguin, I try downloading Python, and it doesn't work. It says no file found.
It recently stop working completely :-(
The extension did not respond when I clicked on the extension icon. It also did not respond when I clicked on the 'Open ALL' option in the context menu. I think the issue might be that the extension was not pointing to the correct executable location. In my computer the Firefox.exe file is located in 'Program Files' and not the 'Program Files (X86)' folder. However, even after I tried to update the Executable file location and it did not change anything. I would suggest adding a browse folder link to open a window that lets the user manually browse to the executable file location in order to ensure that there is not syntax error.
did not work for me the one by yokris.dev did
