How would i know how you can reproduce this issue? Hoping you could tell me how to stop this issue. Google search indicates Mozilla has it designed to open multiple sessions….

Somehow you've managed to make Firefox use too much memory. Just describe here, step by step, how to do it so that we can understand the problem and find a solution.

Firefox is default browser. When we open a session task manager shows 7 to 10 sessions running using a lot of dats- usually bogs down.

OK. Enter about:processes in the Firefox address bar and sort your processes (not sessions) by memory.

Then make a screenshot and attach it here. Thank you!
