Usually great stuff. Mostly useful for finding max curios. Doesnt work anymore since the Atoma.cloud website rework and needs to be updated.

Very helpful, needs to be updated for the itemization changes though.

It wants me to login to steam with my password but I am already logged in on Firefox / Windows!

I had the same issue, having accounts.atoma.cloud opened you have to go to Extensions menu in Firefox and give the addon permission "to read and change data on this site", now it works perfectly for me.

Excellent extension, but at least as of Jan 25, 2024, it no longer appears to work.
It prompts a login to accounts.atoma.cloud, but after login, the Armoury Exchange UI is absent.
For those who want an alternative, he Chrome version appears to still function normally: https://chromewebstore.google.com/detail/armoury-exchange/hcjihmkcnjkfkaeebhnpjcnnibpoolgc

The requires an update, the new weapon types in the December update are bugged in this add-on; otherwise great

Excellent means by which to get the perfect weapons so only my skill causes me to fluff runs.

Community fixing the broken game. GJ!
Does not work in Firefox since circa 02.2024
