Trying to watch a video on Nebula and it will not load. Receiving the following errors:

NS_BINDING_ABORTED Media resource https://nebula.tv/static/small-video-h265-DaPPbwJq.mp4 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_NOT_SUPPORTED_ERR (0x806e0003) Details: Utility MF Media Engine CDM only support for media engine playback

Just made a new profile and wiped everything from my history following another issue which isn't strictly speaking resolved. I am unable to load image-dense websites with any consistency. Issues do not occur on other browsers. I receive similar errors on Twitch:

The website in question loads great on other browsers and on a new profile. I have attatched images of the website open on original and new profiles. On new profile i didn't change any settings. Things i have tried: 1. disable all extensions 2. disable strict security settings in firefox 3. reset all windows 11 internet settings 4. reset firefox through about:profiles > Restart with addons disabled > Refresh Firefox 5. just to check i tried to copy all the original profile settings on to the new profile, and the website still opens fine, with all the same wxtensions enabled too.

This has only started happening recently. I use that site for publishing articles, it is based on OJS. What more can i try?

Hello. I get this screen quite often in response to a search, mainly from a Google search. It started about a month ago. I have deleted must of the junk that Firefox accumulates, as well as refreshed Firefox. This is running on Windows 11.

When I start Firefox in the morning, I normally have multiples pages open, which I need for work. Over the course of the day, the websites become unreadable in terms of the fonts and even new pages I cannot see all of the fonts. I have attached a image from a new website I loaded and if you look above username and below log in you will see messed up fonts that are unreadable. They even print that way. I have to exit all pages and restart Firefox to make it go away. It is a pain to have to do that and re-log into all the sites I need open during the day. This has happened for about a year. I update it all the time and it never fixes it. I have a desktop computer. I have windows 11 professional. I have all updates to windows and all updates to programs in Microsoft Store. I have Firefox 152.0.6 (64-bit). I have reported this before but go not useful information from the report I put on here.

I'm suddenly getting a blank, white screen when attempting to open GMAIL What got broken and how do I fix it?

I verified that the exact same link works fine in EDGE, so this is some kind of recent change specific to FIREFOX.

So, If anyone knows about what i am talking about is that. When loading an Roblox Item from the Martketplace or your invetory or any other page it just not appearing now i do have some adblockers but even if i disable them nothing works I will Also attach an Photo now.

received an email from a website, Chewy.com, about upcoming order. I clicked on Chewy's manage order button that should have taken me to their website so I can make any changes. What it did was tried to open up their website in a new tab, but the tab was blank. I refreshed the website and got nothing but a blank website page. I cleared my cache and tried to load the page again but still received nothing. This is not the only website this is happening to but others like Walgreens, AT&T,

Since the update I performed today, 4/27/26, I am unable to upload files to my NAS via the Firefox web browser on a Windows 11 PC. I can still do it via the Google Chrome browser so I am not completely crippled, but it would be nice if I could still use Firefox for this work. Any suggestions on how to fix this, or will it require the software itself to be fixed?

Hello. I have a question about Firefox. I shut down my PC and turned it on two hours later, but Firefox is still displaying page layouts properly, images on pages aren't displaying, and the screen remains blank even when I load a page from a bookmark. How can I fix this? This is the first time I've seen this happen, whether I've restarted or shut down and restarted.

Am trying to access a TV site and the site appears as a page but does not provide any functionality for days now. Have contacted the site and followed their advice without any results. Could this possibly be a Mozilla issue?

The site address is https://www.ertflix.gr/#/show/Home%20Guest
