I am using a Dell Laptop with windows 11 and something corrupted Firefox browser with the Metamask add on. I got help to get firefox working and the tech had me delete items I thought were totally unrelated to Metamask and they got firefox working. But now Metamask does not stop to allow me to use my pass word. Now Metamask goes straight to a page to start a new wallet or to use the 12 word pass code. That does not work either. Now was it a firefox browser problem or Metamask. In any case I have some crypto in that wallet that I can not access........yet?

This has been working great until Firefox 107 (Mac OS Catalina). Now, as another user also observed, it has a massive memory leak that eats up all the RAM, loads the CPU, and eventually crashes the machine. I really hope my comment is seen and this gets fixed soon. Other than that, it's been great and mostly reliable. It did crash and fail to load about a year ago and I had to manually re-add all of my wallets and tokens again, but hopefully that won't happen again.

Ok

Installed this on my browser and 15 minutes later I lost over $500k in NFTs. Nobody can tell me how or why... Can't say definitively this is the cause. But it's certainly on my radar now.
