Well, one thing to note here is that browsers ─ both the applications themselves and the content they are showing ─ are extremely memory-hungry, and Firefox in particular has since time immemorial been notorious for its memory leaks.
In addition to that, your inxi snippet tells us you’ve got 8 GiB of RAM installed. With a browser open at two tabs, one of them playing a video, and a few other things in memory, your system will start swapping. And swap is not as fast as RAM.
I dont use brave actually, i was setting up the global menu in the kde panel and it was not working for firefox so i just installed the first browser i seen in pamac software manager. FYI i also have falkon installed as well.
Later i got to know that firefox has weird implementation of menu and Global menu doesnt work for all application.
You dont have rephrase your sentence too look nice btw as about information i didnt know where my memory is being used, the system monitor didnt helped me either.
so i provided what i could…
My system boot up around exactly with 1GB make sense as i have latte dock and few others thing setup…
