By any chance could you perhaps share information about the leaky website? If not here, perhaps send me email?

The memory report does show that one child process (something which loads a web page) uses lots of memory, mostly javascript.
And there seem to be quite a few addons too. Have you tried disabling some of the addons?

Hello, unfortunately I don't remember for sure the exact site for the memory-report. But it did happen multiple times with different sites, for example Reddit & Youtube. Closing tabs didn't help with the issue, only closing Firefox from task manager did temporarily, if I remember correctly I opened the memory report tool when only Firefox default home page was on (after closing other tabs).

I also did try running Firefox in safe-mode (which should disable extensions) when the issues were occurring and it didn't help with it. I haven't noticed the issues recurring after that day.
