Toster Extension is a browser extension that enhances the capabilities of the Хабр Q&A website. Developed by Ярков Алексей, this free extension adds missing features or modifies existing ones to improve the user experience.

The extension offers a range of useful features that have been developed based on the author's personal needs and user requests. Some of the key features include the ability to use Ctrl+Enter to submit forms, the ability to save entered text in answer/comment forms before submission, duplication of pagination above question lists, hiding of questions with solutions, and the ability to create blacklists for tags and users.

Toster Extension goes beyond these features and offers even more functionality to enhance the overall browsing experience on Хабр Q&A. The developer, Ярков Алексей, is open to dialogue and welcomes any suggestions or feedback from users.
