⚡ PAGE KEEP-ALIVE
Keep Your Tabs Working for You.
Do your browser tabs go idle while you're working elsewhere? Do supported web applications become less responsive when left in the background?
Page Keep-Alive helps counteract browser background throttling and maintain activity signals that supported web applications may rely on.
Designed for people who work with web applications throughout the day, Page Keep-Alive gives you control over background activity, site-specific behavior, and additional productivity features.
