I-Firefox Support Forum

Hi All,

This salesforce site is working in safari, chrome and edge but it is not working in the latest Firefox browser. It crashes after getting stuck for minutes. Is this technology not supported by Firefox?

The lag is very problematic to me, because I do most of my work using the browser. When the keyboard starts lagging I can only enter text using copy/paste with mouse (which works fine). The only way to solve it is to restart Firefox (which can result in lost work).

The lag, when it starts, is 10 seconds or more for each keystroke. It occurs about once every few days.

Ubuntu 22.04.4 LTS

126.0.1 (64-bit) Mozilla Firefox Snap For Ubuntu Canonical-002 - 1.0

I don't use Wayland.

Setting accessibility.force_disabled to 1 did NOT help.

Some lines from the top when this happened:

I've been dealing with this issue for a long time now, without finding any solution

On macOS, whenever I am using Bluetooth headphones (Sony XM4, Airpods Pro), videos will hang for a few seconds just as the video is starting. This happens again if I pause/unpause or if I seek forward/backward on a video. The video "spinning animation" will appear and it will take 2-3 seconds for the video to start. This happens immediately, even if I click pause/start fast (ie: this is not after some delay necessarily). Also, if I mute audio on the video, the issue does not manifest itself.

During the waiting, Firefox itself seem to be hanging: for instance if I click on an extension icon in the toolbar, nothing will happen until the video finally start playing and then the extension menu will open up

When using Google Meet or Zoom for instance, I sometimes have to wait up to 10 seconds or so before Bluetooth Audio/Microphone starts after I've joined a meeting.

The issue is not specific to these platforms: I experience the same issue on other platforms such as Facebook, dailymotion, vimeo, zoom. On Facebook, since videos start muted, I can see the videos start playing right away, and then if I unmute sound the video stops, and start again with sound after 3 seconds or so

The issue does NOT manifest itself when playing an audio-only stream: ex Soundcloud or local radio stations audio stream

Things I've tried and didn't help - Troubleshoot mode - Different Firefox profile - Different Firefox install - Restarting my system

This feels like Firefox/macOS is waiting for Bluetooth to activate, or something like that. I have a feeling this only happens for certain types of video/audio codecs but I am not sure how to validate that (ex: no issues on soundcloud, petron audio-only posts).

The problem is entirely non-existent when I'm using sound output that is not Bluetooth.

This does not happen with other browsers otherwise I wouldn't be posting here :)
