Download Media with Cobalt API - Adds a context menu item to download media from supported video sites using a direct URL.
VK: Friend Requests Bulk Operations - Manage your friend requests. Add all friends or cancel all subscriptions with just one button click. Very handy if you are a public person or a YouTube star with VK account for publicity, like my wife :3
VK and Telegram.org: Make the 'Go up' clickable area narrower - Makes the clickable area of the 'Go up' feature on the left side of pages on VK and Telegram.org narrower (fitting the width of the highlighted section) rather than covering the entire left half of the page. It can be very annoying when you accidentally click anywhere to the left of page content and are suddenly taken to the top of the page.
