Firefox 140 : Developer-Centric, Privacy-First, Performance-Driven

Explore Firefox 140, featuring manual tab unloading, improved privacy controls, and performance optimizations for developers and heavy workflows.

Manual Tab Unloading: Take Back Control of Your Memory

Firefox 140 introduces a powerful manual tab unloading feature allowing users and developers to reclaim system memory on-demand. By right-clicking on one or multiple tabs and selecting “Unload Tab”, tabs are suspended but remain visible, saving RAM without closing your work.

This explicit user control surpasses Chrome’s automatic background tab suspension by putting the power directly in your hands, ideal for memory-heavy sessions or development workflows.
