EDIT (20/02/23) : Following dev's response, I reinstalled the latest Kee version, and for some reason it did not force me onto creating an account on KeeVault anymore, and actually synced with my local KeePass.
Sorry for the trouble Luckyrat and thanks for that great extension <3

-------------- Before edit below, not applicable anymore --------------
I've been using it for years along with KeePass and it was great, but version 3.10.10 was the end of it : it now requires to create an account and pay a yearly subscription.

Thanks but no thanks, I will stick to v3.2.7 which worked flawlessly, for free, and without asking for my information.

Very good tool, it's so needed in my workflow.
One more extension that keeps Firefox being the best browser for me, since mid-2000's !!

Expansion is an integral part of the workflow. 10/10

good application

quelle galère, il ne trouve jamais le logiciel qui est pourtant ouvert, tous en anglais et hyper compliqué... je le vire au bout d un an de prise de tête....
