Not sure what that is, could you expand or point to a resource where I could learn more? Thanks.

- acdha 12y agoOpen the location bar and type "about:memory" – it displays all of the memory usage in Firefox by component so you can look for hot spots. Once you've opened it, click "Measure" and you'll get a huge tree view of memory allocations. Simply searching for "add-on" should quickly give you an idea of whether you have a known hog like AdBlock Plus or something more subtle.
- bsbechtel 12y agoThanks. It looks like there is a huge amount of memory devoted to recently opened tabs that are now closed, especially from js heavy sites. I run a session manager extension, so that could be the source of these sites still using resources. I'll try disabling it and seeing if anything changes.
