Common Questions About Tab Suspender Tools

What is the difference between suspending and discarding tabs?

Suspending replaces the tab content with a lightweight placeholder page. Discarding uses Chrome native API to free memory while keeping the tab visible in the tab bar. Suspended tabs need to reload the page when clicked. Discarded tabs also reload but the process is handled by Chrome itself.

Will tab suspenders lose my form data?

Most tab suspenders will cause unsaved form data to be lost when a tab is suspended. Good suspenders like Tab Suspender Pro detect tabs with unsaved form input and skip them. Always whitelist tabs where you are filling out long forms or composing messages.

How much memory do tab suspenders actually save?

A typical web page uses 50 to 300 megabytes of RAM. Suspending it reduces usage to under 5 megabytes. With 50 suspended tabs, you can save 2 to 10 gigabytes of RAM. The exact savings depend on page complexity, embedded media, and JavaScript memory consumption.
