Saved Password Editor 2.10.2

Windows 10/Firefox - now updating to 50.0. It may change things.
For the first time ever, I cannot edit my passwords.
No errors; just no response from add-on. Whatever line I choose to edit, it bounces back to the top line.
I can open and view passwords on the opening page, but that’s it. I cannot click on any individual feature.

This installation also lags for a fraction of a fraction of a second after clicking “close.”

I don’t know how long I’ve been using this, but it has performed excellently and restores well after having to wipe out all data and start again.

After the update, the same problem still exists.

Thank you.

Have you tried contacting the developer? There’s contact information in the add-on page. Also, there appears to be a new version available. Maybe it fixes this problem.
