Kudos!! The extension is a must while learning Vue atleast. I would like to request you to provide a similar extension for Firefox.

Please! can i expect it?

Update: (17-March-2017)

It is now possible to use (chrome's) vue dev-tools in Firefox.

1. Install Firefox Developer Edition
2. Install Chrome Store Foxified extension
3. Now go to Chrome Web store and search for vue- devtools, you will now see an Add to Firefox option
4. Once you click on Add to Firefox you will get a pop up with different options, choose Save Signed Addon option and save the file to your disk.
5. Now navigate to about:addons in Firefox and click on the gear icon in the top right corner (just before the search field), you will see an option Install Addon from File in the dropdown menu.
6. Click Install Addon from file and choose the file which you downloaded and saved in Step 4.
7. The vue-devtools will get installed in Firefox, restart Firefox and start using vue-devtools in Firefox.
