BitDefender Wallet Troubleshooting with Quantum

Hi,
BitDefender Wallet addon, working for previous Firefox versions, now isn’t working with Firefox Quantum. I need it because it’s my password manager and I work with it.
How can I solve this?
Thanks

Try contacting the developers of the add-on for help.

Bump! Still having this problem. Trying to contact Bitdefender online support but I always get the guys who refuse to believe I know what I’m talking about.
