Actual results:

Nothing? I thought the most recent update would fix it but it hasn't. I read that the memory leak is because of a specific theme but i don't use themes so i'm... unsure. i'm not tech savvy either i'm sorry.

task manager shows cpu at 39% and memory are 4.5k

There are many possible causes of memory leaks in Firefox. We need more information to understand the problem. What has lead you to say that you are experiencing a memory leak? How much memory is your system using? Where are you seeing that? Does it happen quickly or slowly?

None of the processes in your report have super high memory usage, but there are a vast number of structured clone holders

Main process:
41.70 MB (08.90%) ── structured-clone-holder [12940]

Pinterest process:
196.44 MB (46.10%) ── structured-clone-holder [107618]

Google processes:
228.23 MB (57.70%) ── structured-clone-holder [125612]
83.41 MB (23.61%) ── structured-clone-holder [43853]
183.99 MB (55.75%) ── structured-clone-holder [103553]

Truity process:
226.39 MB (68.76%) ── structured-clone-holder [123858]

Maybe this is related to an addon, but I'm not sure if there's any way to tell from the memory report.

I only assumed memory leak since that was what google said when I tried to figure out what was wrong. I'm sorry, I don't know much about this sort of topic. In task manager when this starts to happen it shows 80% of my PC memory being used and a large chunk of it is from firefox (at the moment it's using 5k mb total).

I tried turning off some of my add-ons/extension to see if the problem would slow stop but it didn't seem to work. It happens slowly, but it seems to start freezing more when I open a google doc/sheet for the first time.

From the profile, I think the Kaspersky addon might be the problem. Can you please try disabling it and see if this stops or reduces the problem?

Hello, sorry for the late response, but after disabling the Kaskersky addon the problem stopped. Thank you for your help and thank you to everyone who responded!

The latest release of Firefox includes more details in the about:memory report. Could you re-enable the add-on, trigger the bug and generate a new dump from about:memory?
