Hello, I have some issues, when Firefox is not minimised. When I watch movie on my BS Player or playing World of Tanks and I have not minimised Firefox (there is a window, no matter it is maximised or just window), there are visible FPS drops, but when I minimise the Firefox window, it works just fine. Also when I connect my laptop to my sound amplifier with 2.1 speakers, I can hear a jamming, hamming and whirling, also works fine, when Firefox is minimised. Is there any way to remove this? Its quite annoying. I tried to disable all addons etc., nothing worked. Thanks.

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.
