New Tab Suspender for Firefox

New Tab Suspender is a very lightweight Firefox extension designed to help you reduce your browser’s memory usage by automatically suspending inactive tabs. By leveraging Firefox’s native discard API, this extension ensures that unused tabs are put to sleep, freeing up valuable system resources and keeping your browser running smoothly.

Why Use New Tab Suspender?

Modern browsing often leads to having many tabs open at once, which can quickly consume a large amount of memory and slow down your computer. New Tab Suspender solves this problem by suspending tabs you haven’t used in a while, making your browsing experience faster and more efficient.

Key Features

• Suspend inactive tabs: Automatically suspends tabs after a set period of inactivity using Firefox’s native discard API.
• Customizable timeout: Choose how long a tab should be inactive before it is suspended (e.g., 5 minutes, 10 minutes, etc.).
• Whitelist support: Prevent important sites from being suspended by adding them to a whitelist.
• Ignore audible and pinned tabs: Keep tabs that are playing audio or are pinned always active.
• Disable/enable extension easily: Quickly turn the extension on or off as needed.
• Localization: Full support for English, Hindi, Spanish, Russian, and French.

How It Works

Once installed, New Tab Suspender runs quietly in the background. You can set your preferred timeout for suspending tabs, manage your whitelist, and choose whether to ignore audible or pinned tabs. The extension’s simple interface makes it easy to configure your preferences.

When a tab is suspended, it is discarded from memory but remains visible in your tab bar. Clicking on a suspended tab will instantly reload it, allowing you to pick up right where you left off.

The extension provides a straightforward options menu where you can:

• Set the suspension timeout (e.g., 5 minutes)
• Add or remove sites from the whitelist
• Choose to ignore audible or pinned tabs
• Temporarily disable the extension
