Browser freezes in both kali and debian linux

[w.h.0]

I am facing this issue more than 3 weeks. When i using lots tab in the browser suddenly browsers starts slowing down like scrolling is kinda laggy , when trying to close tabs , tabs are closing after 10s of clicking cross of tabs, switching to different tabs are also looks like it freezes. And literally i downloaded brave for less memory usage but brave has started taking more than expected space. I remember at first brave took max 1 gb or something like that now its taking too much memory space. another issue i face when coping something from website it literally turns into black background which is disturbing. usually happens in try hack me web. i can do normal copy paste in firefox not in brave.

Description of the issue:
How can this issue be reproduced?

1. By opening lots of tab

2. By using brave more than an hour.

3. while copy and pasting from try hack me website

Expected result:

Brave Version( check About Brave): latest one

Suggestion:

Brave Browser Task Manager window that displays column titles:

→ Task | Memory footprint | CPU | Process ID | Image cache | Script cache | GPU memory | JavaScript memory (<-- that creeps up)

When you add columns in the Brave Browser Task Manager window, they may not appear in that same arrayed order.

That monitoring, along with your Operating System’s monitoring that you have been using.
