Subject: Feedback on Performance Scaling and Resource Management for Heavy Web Applications

Thomas Prigl

Dear Mozilla Team,

I am a long-time, dedicated user of Firefox. Recently, my workflow has shifted heavily toward modern, resource-intensive web applications (such as large, stateful AI chat platforms, complex dashboards, and heavy documentation tools) that handle massive amounts of text and DOM elements over extended sessions.

While Firefox’s multi-process architecture is generally robust, power users often have to resort to tweaking hidden settings in about:config (such as adjusting process counts) to prevent performance degradation, memory management friction, or sluggish re-rendering during heavy, long-running tasks.

It would be fantastic to see more accessible, user-facing performance profiles or advanced resource-management options directly in the Firefox settings—for instance, a dedicated "High-Performance" or "Power User" mode for heavy web apps. This would allow users with high-end hardware (such as 32GB+ RAM systems) to explicitly allocate more resources and processing power to specific tabs or workloads without compromising the stability of the rest of the browser.

Thank you for continuing to build such an open, customizable, and user-focused browser!

Best regards, Thomas Prigl

Hi,

The people who answer questions here, for the most part, are other users volunteering their time (like me), not Mozilla employees or developers. When a Mozilla employee jumps into a discussion, you'll see the Mozilla Staff label next to their name.

If you wish, you can leave feedback for developers on the Mozilla Connect website. Click the Firefox Menu Fx89menuButton button in the toolbar, click Help and select Share ideas and feedback…. Alternatively, you can use this link. Your feedback is collected by a team that reads it and gathers data on the most common issues.

You can also file a bug report or feature request. See File a bug report or feature request for Mozilla products for details.
