Tab Memory is a fast and lean Firefox extension to monitor tab memory usage. It displays memory usage of individual tabs next to the tab's title. Memory usage is calculated upon tab updates to prevent Firefox slowness.

FAQs:
How does Tab Memory Usage work?
Firefox has a built-in API to determine the amount of memory each JavaScript/non-JavaScript objects consumes. This extension fetches these data for each tab and displays the result as a label adjacent to the title of each tab. To improve extension's performance, memory report is performed for each tab individually just after the tab gets new updates.

1. Why there is no memory usage indicator when a new tab opens up?
To improve performance, memory usage calculation is only triggered when a tab is refreshed or get updates. A black tab usually uses less than a mega byte of memory and hence the extension skips blank tabs.
