Steam Bulk Sell is a web-extension for Firefox to help selling multiple inventory items at once. It allows one to select multiple items, use prices presets (median, median * multiplier, custom) and sell them. - Does not require any permissions, except for Steam inventory pages - Allows to select whole inventory tab at once - Prices are loaded asynchronously - just open sell modal once and the extension will start fetching prices for currently checked items, close modal and continue selecting/deselecting items - Prices are fetched from Steam, so expect ~1s delay between requests, ~2s delay for each selling action - Open source - feel free to contribute!
