About 2 weeks ago it stopped working, it freezes on the loading page.

Suddenly stopped working (stuck on loading screen), restart, re-enabling does not help. Lost access to bunch of my private keys, don't recommend.

The extension stopped working, or it is very intermittent. You key in the password, and it does not go any further

It keeps crashing
I saw it use up 90% of RAM and cause Firefox to freeze
