We’ve worked on reducing CPU usage in the extension. We increased the check interval for heavier tasks, fixed a potential issue where the extension could endlessly attempt to refresh Steam service authorization, and resolved an issue where the extension would endlessly reconnect to the websocket service.

Our extension requires maintaining a constant websocket connection to transmit commands for trade creation. To achieve this, we use the browser.alarms API. In Chrome, the wake-up interval is set to 2 minutes. In Firefox, it’s set to every 10 seconds (otherwise, the extension may miss websocket events and constantly reconnect to our servers).

If the issues persist in version 1.5.0, please record a video showing the extension’s behavior and send it to our support team, requesting them to file a bug (https://market.csgo.com/ru/usercab/support).
