I have competed the 2FA activation with no issue, but am unable to upload my LotW certicate to get verified. I'm using windows with a Firefox browser. I have saved my LotW cert in a .p12 file and steps 1-7 of the firefox/windows instructions. Step 7 says to "view certificates" in the firefox browser. I do that, and then click on the 'next' button to get the next step (since it seems there must be a next step after simply 'viewing certificiates') and then I get: "No Certificates Were Provided By Your Browser" And kicked back to the start of the process. Seems like a step is missing somewhere (like telling the browser where the .p12 file is located)? Any help is appreciated! Kevin.
