Sometime the wallet functions, then sometimes you nowhere without function.

nice

It's legit and it hasn't been scammy, however it's incredibly buggy and poorly designed. Right now it can't start at all. It sometimes just breaks. That is horrible if your money is relying on this tool working properly on time. Also the UI is not great, especially for gas fees - sometimes I've had a transaction be reverted and it was completely unclear that this was even possible; I constantly had to use "custom" transaction speed and look up gas fees from a 3rd party website because the in-built tools weren't good enough. I'd recommend using a different wallet if possible - for example, Phantom is good. (Also there was a time where I lost the opportunity to earn a few thousand dollars since I was minting NFTs very slowly, because of Metamask on mobile acting very badly under poor network conditions, but I cannot honestly blame them for that - most software isn't designed and well tested for that. 95% of the fault was mine, for not foreseeing that most software gets buggy/bad with unreliable network.)

Lately has become unstable...

32gig ram, i7 13g seems to be insufficient to run Metamask in Firefox
It is getting heavier with each update. Long load. I am afraid it will damage the RAM or SSD.
Maybe the activity and nft section on the home page can largely cause this heavy load.
Very often there is this annoying problem: when making a transaction on a site, the network I am trying to transact on shows correctly in the pop-up, but the transaction fails with an Internal JSON-RPC error. When I open Metamask, the connection network is something else.
Please add a network search field in the Send Token section. I have to search for the network I want from more than 50 networks every time. It is really annoying.
select the network and permissions in previous versions was much better, easier and faster. The reason for this change is really annoying
I hope these problems are resolved very soon. ex updates in Firefox are always behind Chrome :(
Anyway, thanks to the team.
I hope to continue using MetaMask after 4 years.

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.

The only official metamask wallet that exists on Addons.
