Review summary

User reviews show mixed experiences: when the Audio Equalizer works, it can noticeably improve audio quality (clarity, bass control) and is praised for being user-friendly and among the better Firefox EQ options. However, a large share of reviews report instability, including site breakage, video playback/format errors, and inconsistent performance across sites (YouTube/Discord) and browsers. Some users also note memory/stability issues. Overall, the addon can be effective but is frequently unreliable, with significant compatibility and stability problems across many popular sites.

Pros

Improves audio quality when it functions (e.g., clearer speech, better balance)
Helps with poor-speaker setups by reducing certain frequencies
Simple, usable control panel/interface
Regarded by some users as one of the best Firefox EQ add-ons
Often praised as reliable when it works/displays solid performance in favorable cases

Cons

Breaks websites and video playback across multiple sites
Does not work on YouTube and other sites (Discord mentioned) or often has no audible effect
No video with supported format and MIME type found errors occur on multiple videos
Inconsistent performance across sites/browsers; works sometimes, but often breaks or is unstable
Memory usage and stability issues after extended use (potential performance impact)

2026-04-20	SM*****	This extension caused a critical issue with video playback on certain websites that use CDNs and HTTP Range streaming. After installing it, videos would not load in Firefox in normal mode, showing the error “The media could not be loaded…”, while ads and other content played normally. In DevTools, media requests returned status 206 (Partial Content), but were marked as “blocked”, indicating that the data stream was being interrupted on the client side. Interestingly, videos worked correctly in Firefox’s private mode, which made the issue harder to diagnose initially. This behavior suggests that the extension interferes directly with the media playback pipeline (MediaElement/WebAudio), causing conflicts with browser security policies (CORS/ORB) or segmented streaming. After removing the extension, the problem was completely resolved without any changes to browser settings. Use with caution, as this extension may break video playback on sites that rely on CDN-based streaming or cross-subdomain media delivery.

2026-04-13	al*****	does not include a voice/speech/podcast equalizer set. no way to import equalizers nor sync them to my firefox account - so re-entering a preset visually on 5 firefoxes after each major firefox upgrade is not sustainable
