Features & Capabilities

Tab Suspender Mini enhances your Firefox browsing experience by automatically suspending inactive tabs, freeing up memory and reducing CPU usage. Designed as a lightweight extension, it replaces inactive tabs with a custom suspension page storing the original URL and title, ensuring efficient resource management.

Key features include automatic suspension with customizable timers, immediate suspension of current or other tabs, and toggle options such as lightweight mode and screenshot capturing. The extension also offers domain exception handling to prevent suspension of important sites, with easy management via the popup interface. Additionally, it protects tabs playing audio from suspension and safely ignores internal browser URLs to guarantee smooth operation. Source code is available on GitHub for transparency and customization.

I appreciate that this extension has more options than the original Tab Suspender extension. This extension does a good job with the suspending of tabs, but the unsuspending of tabs is not working smoothly on my end. Each time I open a suspended tab and go to un-suspend it, the browser locks up as though it's processing a huge amount of information. Firefox becomes unresponsive for about 15 seconds before I regain control and the tabs eventually reload. A message appears on-screen stating that the tab is slowing down Firefox and asks me if I want to kill the tab.

Works seamlessly, screenshots are fast, and handles website icons perfectly. Current issues I have: -Shortcut to suspend current tab doesn't work for me (and would be nice to be able to remap it EDIT: turns out you can in the firefox settings, and it's just the default shortcut on Windows at least that doesn't work) -Would be nice to have the option to disable the suspension timer entirely. I'm coming from chrome using the marvelous suspender, and I prefer to manage things manually -Another feature from that extension that would be nice to have here: A button to suspend all tabs in the current window only Thanks!

Is Tab Suspender Mini Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Tab Suspender Mini requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
