recovery keys

more options

I have two recovery keys, how can i check which is the one set for my preferred installation of Firefox. One was for my en-CA install, the other for an en-US install made a week later due to an update glitch. I had to use my en-CA recovery key to recover my settings to the en-US install, which also made a new recovery key. I want to get rid of the spurious en-US install.

Now i don't know if that new recovery key replaced my en-CA install's key.

en-CA is in it's original location c:\program files\mozilla firefox

en-US is in "C:\Users\%username%\AppData\Local\Mozilla Firefox\firefox.exe" the directory trees appear the same except en-CA has a locale.ini file that the other does not.

Despite search results to the contrary there is no longer a way to view the recovery key in Firefox.
