My favorite thing about using the MetaMask extension is that it doesn't work 98% of the time. It was constantly not fully loading, they fixed it, and now its back to the same not loading again. The same answers for help are, "close browser, try again" ... yeah, that doesn't work.

It crashed 3 times in a row :(

Horrible experience. Metamask has become trash at everything.
This extension is slow, full of bugs (you need to refresh it many times). The pop-up windows and the app page often don't match. For every single operation (like reviewing your wallet or opening a token page) there are a lot of stuttering, connection issues, freezes and so on.
Metamask has become literally trash, even the Android app has the same issues. Also, it has too many spam pop-ups during navigation to convince you to buy its useless services.

Avoid Metamask wallet like the plague.

It became so bloated that even on a reasonably new computer it takes forever to do basic stuff.

It was a nice addinn, but right now I'm better off without it.

I have no idea how it works, but after metamask changed the UI, it becomes garbage. And it will continues loading sth in the background and finally it eat all my memory (FYI, used more than 15GB RAM) and affect my whole PC WTF... BTW I don't even unlock it and it still running in the background.
After I disabled metamask extension, Firefox become normal and as smooth as before. Very disappointed to metamask.

Ой! Что-то пошло не так.
