“Task Manager” addon for Firefox?
Chrome has a built in task manager under "Tools" to look at the process within Chrome, extremely beneficial in locating a stuck page. What is the similar feature in firefox?
I need to identify what is causing it to run slowly, and the addons they suggested dont work for OSX or are outdated, and Chrome's about:memory isn't recognizing FF
How to get to Task Manager:
Task Manager:
Short answer: FF doesn't have a task manager because it doesn't use tasks.
Chrome is unique among web browsers in that it each tab renders its web content using its own OS task. This approach relies on the fact that modern processors have a lot of extra capacity and don't get bogged down by the high overhead of spawning a lot of tasks. You can see this in action by using the OS's task manager to view all the Chrome tasks:
Older browsers were designed when processors were less powerful. They tend to make less use of concurrency. And when they do use it, they rely on threads which have less overhead, but also make it harder to limit the effect of errors.
