I use eBird extensively. When I try to play the audio (with sonograms), I get a message that says "We are still processing this file. Try again later". These files perform well on my Android phone, so I know it it is not eBird's glitch. I am confused about the setting options on Firefox that I need to set. These files are usually .wav format. I have tried to open a ticket with eBird, but have not had a response. Can you guide me? Thanks.

I'm not sure when it started happening, but whenever I'm watching something full screen, or just full screening, Firefox on Mac, there's this thin white line at the top of the window that's very distracting. Has this been happening to anyone else and does anyone else know how to get rid of it?

Hello there.

Since last update i'm unable to browse websites like youtube, social media and all other websites with video content. Video often fails to load,the wholewebsite is not loading, freezes while played or while exiting full screen mode. All of these freezes the browser - the site cannot be refreshed, links does not work. The only way is to close the tab with the freezed page or kill the Firefox process in windows Task Manager. Refreshing, re-installing, deleting or using different profile don't work. Same with add-ons. Seems like the issue lies within the browser and it started to appear since last update.

For the past.. month I would say, any time I try to use Youtube on my Firefox Browser it nearly always switches over to landscape mode after watching a video. It doesn't matter whether my phone screen's auto rotate is on or off it still does it. Yes. I already tried to turn my auto rotate on to switch it back to potrait mode, it still won't work. The only solution I currently have is closing Youtube all together from my Browser, which really REALLY sucks!!

Can someone PLEASE look into the glitch?!

The taskbar (the one with the Start menu) doesn't hide when watching videos in fullscreen mode. This happens on YouTube as well as on any other website. The problem disappears if I run the browser in Safe Mode. It's only Firefox that doesn't work — in Chrome the taskbar does disappear.

Lately, whenever I click into a youtube video from within youtube, instead of Firefox blocking autoplay, it mutes the video but lets it play.

Initially, it was muting EVERY video I pulled up, but messing with my settings has fixed the problem if I click into a youtube video from elsewhere (ex. a google search result), or if I refresh the page. It's super annoying to having navigating youtube be this non-functional right now, though, since everything just silently plays until I catch and unmute it! Any help would be super appreciated!

(I'll attach an image with my current autoplay settings.)

Is anyone else having problems manually playing videos after selecting Block Audio and Video in order to prevent videos from auto playing? I got sick of videos starting automatically every time I navigated to a web page, so I followed the instructions to disable auto play by selecting Block Audio and Video in the settings. Now, when I try to manually play a video, it fails to start. Any suggestions on how to resolve this issue while still preventing videos from autoplaying? BTW, this is occurring on iPad and iPhone rung the latest iOS version.

As of around 6 weeks ago (bit of a guess) I no longer have the option of pausing/playing media on a tab from the tab list. For at least the last few years prior to this issue, whenever I had a tab playing media (mostly video, but sometimes audio e.g. a podcast episode on BBC.com) there would be a small pause button for that tab in the tab list.

I've attached a attachment (2 screenshots merged). The tab with the purple circle is currently playing a MP4 video (streamable.com) and I would usually see a pause button, I think where the circle is located but might have been in a different corner.

I found this Reddit thread which mentions the issue but outside of the 2 people in this thread I have not found any other info or reports. https://www.reddit.com/r/firefox/comments/1rh5gcy/youtube_buttons_playpause_missing_in_android/

Additional info: while playing video, I am able to pause through system notification (see image attachment) so the playback IS recognized. But no pause/play button in tab list.

Unable to play a video on Hulu with my own Hulu account, which I have had no issues in the past doing, even with all my ad blockers and trackers enabled (Privacy Badger, uBlock Origin, AdBlocker Ultimate, Ghostery, and Malwarebytes). I have tried disabling all of the above extensions, refreshing the website and still no luck. I have also followed the instructions Hulu guides me to via a link on the screen (see attached screenshot) to their help page https://help.hulu.com/article/hulu-power-cycle?utm_source=hulu&utm_medium=error-message&utm_campaign=video-02 None of these have helped either. My internet speed is fine, I checked it through 3 different internet speed testers to verify Also checked my Wifi signal through our Google Home portal. I've searched online for solutions and haven't found anything new to help or in the Mozilla Support forum. My computer/laptop is up to date on all updates and software. Appreciate any support, thank you!
