Flow Tabs Pro by Catalyst Tools

The Problem: Mozilla tabs consume enormous amounts of memory. Having 20+ tabs open can slow your entire computer to a crawl.

The Solution: Flow Tabs Pro suspends inactive tabs, freeing up memory instantly while keeping everything accessible. When you need a suspended tab, it resumes in under a few seconds.

Boost browser speed with smart tab suspension. Save up to 70% memory in your browser, create sessions, and maintain perfect focus while browsing.

Cut your browser's memory usage in half while staying perfectly organized.

Flow Tabs Pro transforms heavy browsers into lightning-fast productivity machines. By intelligently suspending inactive tabs, you'll reclaim up to 50% of your system's memory while maintaining instant access to everything you need.
