Hello @weigand​
I'm sorry about the recent change in LastPass behavior there.
There is a new version for Firefox being released in the coming weeks that should help. In the meantime, are you able to re-install the browser plugin to see if that rectifies the site launch ability?
Thanks for the response. I did as you asked, to remove and then re-install the browser plugin for LastPass. There was no improvement. It still results in the "Launch" clicks on the Vault page not doing anything. I'll check for Firefox updates to see if that fixes things.
Updating to Firefox version 134.0 today caused the problem to go away. Clicking "Launch" now works. This issue is closed.
