Is Steam Bulk Sell safe?

Select and list multiple Steam inventory items for sale at once.

This extension adds bulk selling tools on Steam inventory pages, including selecting multiple items or a whole inventory tab and applying price presets such as median, multiplier, or custom prices. It fetches item prices from Steam asynchronously after opening the sell modal and uses Steam market sell pages to submit selling actions. Permissions also support cookies, container identities, and web request handling for Steam pages to work with cookie-isolating add-ons.
