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

I use this addon since more than 1 year, works as expected, no issues, no worries... thanks!

workings perfectly

best extension for keepass

非常好用，不知道为什么评分这么低

Seamlessly connects to KeePass 2.45 on Ubuntu 20.04.
Instructions to set up the extension are straightforward.
Never had an hiccup. Perhaps, it would be nice to add a URL field customizable in the "add entry" option. This would make the extension truly complete.
