A few things.

  • Browsers use a lot of memory
  • Linux tries to utilize memory so when there is no demand for memory from other applications, it may not show as free. That doesn't mean it is isn't available for other applications.
  • Please read through https://www.linuxatemyram.com/. It explains some of this in more detail

Your whole system is using 50% RAM, not just your browser. Run top to see what is using memory.

Here are my Firefox processes tab and system monitor captures. They show the main process using nearly 1GB and the kernel reports it is using almost 2GB in total (including all processes and threads). This is with 4 tabs open. However, if I open 10 tabs it often goes up slower, maybe only going up to about 2-4 GB range and hovering in that range unless I open A LOT of tabs. This is normal.

Modern browsers have a lot of moving pieces and take up a lot of memory. They launch processes and threads for rendering, processing parts of websites, running scripts, decoding audio and video, etc. Most now have a separate process for each tab or set of tabs. They may also allocate a bit of extra memory in anticipation of loading more tabs so that they open faster. Unless the browser starts eating up all the memory when it should be doing nothing (a memory leak), like @dalto said, I wouldn't worry about it.

The other solution is to buy more RAM. :grin:
