Upwork Optimizer is a Chrome add-on developed by James Keezer. This free tool falls under the Browsers category, specifically in the Add-ons & Tools subcategory. Its main functionality allows users to toggle the announcement banner on and off on the "Find Work" page within the Upwork platform.

With Upwork Optimizer, users have the convenience of hiding the Announcements banner on the "Find Work" page by default. This feature provides a cleaner interface for users who prefer to browse through job listings without the distraction of the banner, while still offering the option to toggle it on when they want to view announcements.
