Mozilla’s Process Manager vs Task Manager

Keep note that Mozilla Firefox already has a feature called Task Manager that focuses on memory use and energy use of open tabs and extensions.

However, things are a bit different from Firefox‘s upcoming Process Manager, mostly because the information that it provides is useful mostly to engineers and those interested in technical details.

Available with Mozilla Firefox version 78 and later, this feature is a welcome addition to a browser that is already at the top of the list of many Windows 10 users.

Alternative browsers with similar tools

Another amazing web browser that has a similar feature is Opera GX, and this one is recommended to common users, not just devs.

This is all because Opera GX advertises itself as the world’s first web browser for gamers, and thus comes with gam-boosting tools like a memory and RAM limiter via the GX Control Panel.

This way you can enjoy running other programs in the foreground, without having to worry that your browser is eating up all of your RAM, regardless of how many tabs are open.

More so, GX Control lets you monitor in great detail which process is taking up the most memory, and which are the ones that take up most of the bandwidth.
