How do I find out which extensions take a lot of ram.

How do I run AutoDiscardTab more agressively ? !!!!

The about: keyword in the searchbar enables access to divers tools and configuration pages. There is autocomplete on, so if you can't find a page, it either doesn't exist, or you are misspelling the words.

Unloading Tabs

about:unloads

It displays information about your open tabs, such as the order of priority for unloading tabs, the last time you accessed each tab and the memory each tab is consuming.

Source:

  1. about:config
  2. type sidebar
  3. Scroll down until you see sidebar.verticalTabs
  4. Set sidebar.verticalTabs, sidebar.revamp.round-content-area and sidebar.revamp to true.

Fix gesture swiping tabs not working correctly on linux (laggy, jagged slow movement):

  1. same as above
  2. apz.gtk.pangesture.delta_mode set to 2
