Firefox Community Forum

Hi,

The Firefox browser came through with an update and I found that on Bluesky it is hard to load or see video's, which makes it a slightly pointless exercise.

Previously I have found that after an update (can't recall if it was Chrome, but think it was Firefox) the problems cleared up after a couple of days.

However, that doesn't seem to be happening right now.

Can't think what I should be tweaking at my end.

Whenever I try to full screen in any streaming websites, it's not full screen at all. There is a little bit of space in the left-side and top-side of the screen where the other windows or applications I have can be seen (or my desktop if nothing else is open). This is not happening to other browsers. Can you please help me to fix this?

When I watch Downton Abbey on PBS from outside the U.S, using the Firefox VPN in a Private Window the Closed Captions of the PBS video are displayed TWICE: one above the timeline and the other above it.

This issue is specific to this particular show AND to the Firefox browser.

I was receiving Directv content on Mozilla Firefox for months without issue. Suddenly it stopped completely and left a message "We couldn't play this content at this time". I don't understand why this happened or how to fix it. I want to do all my browsing with Mozilla Firefox so I need help. It would be truly excellent if I could speak to a human about this issue. Please.

Pages not starting to show. Page itself working ok. in Crome works 100% Note: Funny thing is that many of the videos work ok, but some not ??

Whenever I'm on X or Instagram (websites that displays feeds with media), the auto-play video feature sets the volume to the maximum even though I just set the volume to a lower level: like, if I set a Reel or a X (Twitter) video on the feed that was auto-played while scrolling to like 15% volume, the next one will auto-play in the max volume apart from me setting it to low. I already tried to use the Zen Site Volume Manager extension, but it only broke Twitter, blocking me from playing the videos or breaking the page completely.

So I clicked into a video, and it did not play. Further troubleshooting showed it was a video hosted by vimeo, and youtube videos still worked. I tried on multiple vimeo hosted videos, on multiple unconnected websites (dropout, patreon, and directly on the vimeo website).

I tried the following fixes:

• I opened it in a private window and nothing played.
• I booted into safe mode, still nothing.
• I turned off all of my add-ons, nope.
• I cleared my cache and restarted, nothing.
• I cleared my browsing data and restarted, also nothing.
• I checked for updates: up to date.
• I created a test profile, and it works there.
• I opened Chrome and it worked there too.

The test profile/chrome thing suggests it's an add-on or something but the fact that I turned them all off and this still happened has me baffled.

Update: I fixed it. Was user error.

hello my problem is widespread, recently i took my pc to shop because of some system problems, shopkeeper updated my windows 11 to newest version before update i think i had version from before 2025 i think, anyway many old programs i had saved stopped working or started to have problems if they worked, i had to instal new Firefox too because i completely lost the old one, and the problem i had while watching youtube was weird white blinking sometimes, it was very annoying, i searched online for solution and found out that i should turn off hardware acceleration, blinking stopped but now i see weird horizontal line in the middle of my screen while looking at pictures and moving them up or down or watching movie that moves up and down too, i dont mind turning acceleration back on but then resolving blinking while watching videos on Youtube my windows 11 version 25hc GPU Nvidia RTX 3060 driver updated 23.04.2026 version of driver 32.0.15.9636 firefox version 151.0.1

Recently I formatted my pc and after reinstalling windows I immediately downloaded Firefox and synced my profile.

For some reason, videos on some (most websites) are not working at all. They just dont play, and these are websites that I used just last week on Firefox, and that I've tested on other browsers and work just fine. I've tried troubleshooting mode, new profile, deleting cache, etc, and nothing has worked. On some websites, I dont even see the player, its just blank, and in others I see the player but no playback (doesnt even seem to buffer).

YouTube works just fine strangely enough.

Hi, for some time now I've been having problems with Mozilla Firefox, nothing is heard in YouTube, I reinstalled it but still the same problem, in Google Chrome the sound works, what can I do? And this is from the latest update.

When I am in Google hangouts meeting and have anotehr tab open in the browser that is playing music (Youtube), the noise is audible to my hangout meeting attendees. This was never the case until an update of two ago. I do not have this issue with Chrome browser.
