Web browser tab freezing and high memory usage when running dynamic automation tools alongside Proxmox VE web GUI

Hi everyone, I am running into a persistent browser performance issue while managing virtualization cluster workloads and container nodes in Proxmox VE. Whenever I keep an external dynamic web utility tab open here to run background testing scripts and process secondary web workflows while simultaneously managing VM consoles and storage pools in my main Proxmox web GUI, my browser memory spikes heavily and the active window locks up.

During heavy client-side JavaScript execution and continuous web socket status updates, the primary Proxmox web interface becomes sluggish and stops responding to click events or console inputs.

I am also noticing a couple of related interface and rendering glitches across desktop and mobile browsers. Switching between active web tabs occasionally causes input focus loss in novnc terminal frames and text input fields, which forces a full browser tab refresh to restore interactive console control. Furthermore, mobile WebKit browsers seem to experience touch responsiveness delays when navigating node resource graphs and storage allocation tables while secondary script execution processes remain open in adjacent tabs.

Has anyone else noticed web browser tab freezes or memory management lags when running dynamic external utilities alongside the Proxmox GUI, and are there specific browser hardware acceleration settings, memory flags, or WebEngine configurations you would recommend tweaking to keep multi-tab administrative workflows responsive?
 
Pragmatic approach: use multiple independent browser sessions.

Personally I do start "librewolf -P" by default and select one of six defined profiles. I am running three of them in this very moment - for separation reasons.
