Firefox for Android Community Forum

Hello, after updating the mobile Firefox to version 135, I encountered a problem. When I start speeding up video playback on YouTube, a clicking sound regularly appears, as if it’s a micro-stutter in the audio. I uninstalled and reinstalled the browser, and the issue persists even on a clean browser with no extensions. A similar issue also exists in the beta version of Firefox 136 and the nightly version 137, which I installed for testing without making any changes. To check, I installed Firefox 134 again, and the issue does not occur there. My phone, the Tecno Pova 6 Neo, is relatively powerful with an 8-core processor at 2.2 GHz and 8 GB of RAM. Operating system HiOS 14 on Android 14. Could you help me? Thank you.

When listening to YouTube in the background, sound is distorted and stutters frequently, which makes it pretty much unusable. Audio is okay when Firefox is in the foreground, but as soon as I lock the phone, audio stutters appear.

I found one fix on Reddit, disabling HD sound in developer options, but I was unable to try it since nobody explained how to get to these developer options, I wasn't able to find that setting myself.

It started happening since 135, was in beta as well. I opted out of beta because of it, but it came on stable release as well so now both beta and stable versions has this issue.

Has anybody encounter that or have fix?

As explained in the title. On my Galaxy A15, i tested the browser version of Reddit, Youtube, Behance, Instagram and even 4chan. All give the videos as corrupted or stuck on loading.

I already tried cleaning Cookies and site data, the history, already tried disabling all the add-ons, already checked for updates and reinstalling the app. I tested the same websites listed above on Opera and they worked perfectly. Please tell me if there is anything else i should try
