I have about 10 tabs open in Firefox, which isn't a lot compared to what I can do on other computers. My RAM is largely taken up by "Firefox CP Web Content" and I found others experiencing the same issue. Would love to know what that is and how I can solve it.

Comment 1

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Performance' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Comment 2

[Julien Wajsberg [:julienw]]

Hey Alix,
thanks for the bug report.
From the memory report, it looks like Google websites are taking up a lot of memory. This may be a problem in the websites themselves.
It would be good to look at about:processes (open a new tab, type "about:processes" in the address bar then press enter) and have a look which tabs take the most memory from there.

Thanks a ton!
