ntoxeg I am in the same boat. dashlane, when activated, is super slow and laggy, unusable and unable to autofill. When enabled, it slows down the browser often making the whole application freeze for minutes on end. cpu and gpu temperatures go high, fans start spinning, performance is throttled. I never leave the extension enabled for more than a few minutes, if I do, I'll be caught out, and it will take me minutes to disable it, because even browser menus become laggy.
For all practical web survival purposes, I have to copy an paste passwords from an independent dashlane app.
I'd support on Orion+ immediately, but the absence of a plan for Android (I understand the argument why, so I don't need repeating thanks!), and this issue with Dashlane on the desktop experience, are stopping me from committing more seriously to the project. I think I will endure this for a while longer, but eventually, I think password managers must just work for a modern browsing experience it is essential
suggestion for reproduction: open a free trial dashlane account. import your passwords from your other password manager. install the extension and keep enabled as you browse on. see if it freezes.
