EDIT 2: now trades just aren't being created, regardless of whether I try the Firefox or Chrome version of the extension. When I open my sent offers page in Steam I see "Create trade offer for [user]" divs at the top of the page corresponding to my sales, however they all immediately just show "Unknown error occurred" as their statuses. It will still manage to create trades every now and then but it's absolutely getting worse, and frankly at this point I'm sick of getting temporary bans basically every day over something I can't do anything about.

To give credit where it's due, it's great that the infinite refresh bug is fixed, don't get me wrong. But the user experience for sellers is still one of the worst I've ever dealt with. At the end of the day the goal for this extension isn't just "avoid crashing the user's PC", it's "create trades for the user to verify on their phone", and this extension just doesn't seem to be there yet. I can't justify giving more than one star to an extension that doesn't do the one and only thing it's meant to do.

EDIT: tested again after the dev response, it does actually seem to be working now. I've been able to keep it running for a couple of days now without any CPU spikes, and trades do actually seem to generate properly! The only issue (and to be honest I'm not sure whether this is the extension or the site itself) is that notification sounds don't seem to work. Even when I try to create a test notification in the site's settings I just see the toast notification in the top left corner. Strangely I do get a Windows notification but it's hidden by default and doesn't make a sound either.

ORIGINAL (outdated):

Extremely broken, and the Chrome extension isn't exactly better. This one starts spiking my CPU usage from >10% usage to 100%. The first time this happened I disabled the extension since it was recently installed... the problem went away. I tried enabling it again, except this time I must not have disabled it in time because my entire PC crashed and needed to be hard rebooted. Turning off "Automatically refresh Steam auth" seems to have helped quite a bit (are you really refreshing every 5 seconds? and by default?) but I still end up idling at ~20-40% with the extension enabled now, and again, if I disable the extension I drop straight back down below 10%. This is Windows 11, Firefox 138.0.3 (64-bit).

With that said... this extension was indeed able to send a trade, which is more than I can say for the Chrome extension. In Chrome all I could do was keep reopening my trade offers page and hoping the extension would wake up before the time ran out (it never did). Yes, I did watch the video guide (if the user's language is English why does this help link take them to a video recorded entirely in Russian?) but even after turning on subtitles it was useless, essentially boiling down the step of sending the trade to "install one of our various pieces of middleware and confirm the trade in the Steam authenticator when it automatically appears". Can you at least add some sort of manual refresh button for when the extension just doesn't seem to know that there is a sold item that needs to be sent? It's crazy to penalize sellers for situations that they can't do anything about (using the desktop or mobile app is not an argument for allowing your extensions to be in this state, if they were open source then fine but surely I shouldn't need to give you arbitrary code execution on my PC for you to implement a system that other sites have managed without these issues).
