Hello,

I am reporting a performance issue specifically related to Google Search's AI features (AI Overviews) in Firefox 149.0.2 on macOS.

The Issue: When an AI-generated summary appears in Google Search results, GPU usage spikes significantly, reaching up to 212%. This causes the laptop to overheat and triggers high fan speeds.

Critical Comparison:

Firefox 149.0.2: Extreme GPU load and performance degradation when rendering Google AI elements.

Google Chrome 147.0.7727.56: Works perfectly with normal GPU usage under the same conditions.

Tested on two different MacBooks: MacBook Pro (A1502), 16GB RAM, i7 (2015) — OS: macOS Monterey. MacBook Pro (MMQX3), 64GB RAM, M1 Max (2021) — OS: macOS Sequoia (15.x/Tahoe).

Hello

Apparently, a similar subject https://bugzilla.mozilla.org/show_bug.cgi?id=2032772

For information, you can test, add custom search engines in Firefox https://support.mozilla.org/en-US/kb/add-custom-search-engine-firefox

4. In the URL with %s in place of the search term field, copy & paste the URL of the custom search engine.
