MM is just so bad. Some of the severe issues are:
- its sooooo slow. Other wallet like rabby are more than 2x faster signing transactions, why?
- Login often hangs so I have to completly restart FF to fix it.
- Managing addresses ist so much worse than on other wallets and features are just lacking so much behind.
- The mobile version for iOS is just the worst of the worst. My phone gets insanly hot, the app hangs, never updates and crashes periodically. Whoever build that thing is just the peak of incompetence.

I am only using MM because I am too lazy to migrate all my addresses. I really should switch, it has become unbearable.
