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.

not working take infinity leading screen after writing password at start pls fix

Ой! Что-то пошло не так.

Lixo da pior especie

update to 13.4 killed extension with bug An unexpected err ocurred. Which not fixed on update.
New updates made extension MORE BUGGY LESS SECURE AND ITS NOT POSSIBLE TO OPEN IT OFFLINE OR WHEN SOME RPC NOT RESPONDING, there is no more feature switch network and no more possibility to open it offline.

I like old design where everything was simple minimalistic and stable, your updates made it slow and unusable, moreover unfixable crash? I back up everything, but what about others, its not only me according to reviews, and you possibly should receive enough bug reports to start make it better.

MAKE OFFLINE MODE and MAKE IT BLAZING FAST AND STABLE, YOUR FEATURES which cannot be disabled SHOULDNT trigger FATAL ERRORS AND impossibility to check offline wallets details

Absolute piece of shh!t wallet. Breaks more than it works. I'm thoroughly sick of seeing "Metamask had trouble starting" and "An unexpected error occurred." Restarting doesn't fix it and I've reported it a hundred times. I'm not re-installing and re-importing my wallet again for the 30th time to this garbage app that breaks constantly.

Absolute garbage, get's stuck in loading loop every few hours and requires a clean reinstall to work again.

THE SLOWEST WALLET EVER ON FIREFOX! AVOID AT ALL COST!!

Avoid at all costs. You will be unable to login causing loss of funds. Developers have failed to fix this issue for several months. github(dot)com/MetaMask/metamask-extension/issues/35567

Doesnt fucking work

Hi, 
i just wanted to say from the bottom of my heart that this is the worst application i ever used in my life. I suppose you won't care but really i can't express my disappointment in using your service. I am not a social media person. I have 0 influence online so my opinion count 0 in today world. I just hope this message reach the person that is earning money through this application. This is complete a complete failure and no amount on money in the world can pay back the time you make lose me. I have no words.

The metamask extension upgraded to 13.1.0 version automatically under Firefox browser. The login page can not appear and continue spinning and loading

Lately has become unstable...

I am not sure what exactly this addons want to do with 2gb of ram while not having been opened this session? Are the programmers behind this actually trying to use my pc for something else or are you just incompetent?

I bought ETH, and then used the inbuilt swap option, but instead of a swap it was mysteriously transferred to another wallet. Their support couldn't help.
