Extension Metadata
About this extension
EQ Pro is a simple, lightweight sound booster and 10-band equalizer for Firefox.
Most volume boosters have a bad equalizer or break the sound on many sites. This one is a clean, no-nonsense alternative that just works on normal pages like YouTube, Twitch and SoundCloud.
Features:
- Volume booster up to 600% (real percentages: 200% = twice as loud)
- 10-band equalizer (32 Hz – 16 kHz)
- 10 presets: Bass Boost, Voice Boost, Hiphop, EDM, LOUD AF, Smooth Loud, Classical, Pop, Metal, Podcast
- Settings are saved automatically
Unlike many other boosters, EQ Pro doesn't break sites that display DRM content (Netflix, Prime Video, Crunchyroll).
