The "Developer Information" link in the "Developer" section of the release notes page - https://www.firefox.com/en-US/firefox/153.0/releasenotes/ - for Firefox is broken as of v153.0.

1. It attempts to open: https://developer.mozilla.org/docs/Mozilla/Firefox/Releases/153
2. MDN shows a 404 message, and offers a "153" suggested search link which eventually gets me to https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/153

I have not tested this for other regions, but without the "en-US" (and possibly other "language-CountryCode" flavors), the link in the Firefox release notes page will not open the Developer release notes in MDN.

Could be an MDN configuration issue if it's not a problem with how links are generated for the Firefox release notes page.

Let me know if I can provide any additional information. Thank you in advance if this issue is fixed.

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:

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.

http://www.portal.lincare.com. When I typed that www. and it shows firefox cannot open it for me to order the supplies for my CPAP.

I am having trouble getting yahoo.com to appear on Firefox. It worked perfectly for many years but on my current Firefox browser, www.yahoo.com does not work. The page will appear for seconds and disappear. How can this be fixed? Do I need to download a newer version of Firefox?

I have been trying to get amazon prime videos to play. It keeps saying videos are unavailable

threw a little research I discovered that a new update. probably an old update by now .. they could not use the video service.. they had to switch to a different browser.

I'm not switching to the anti-American google to watch a video..

i'm on ver 152 in windows 11

Any help?

Around July 2nd I opened FireFox to find that the text on whatever screen I was on is spaced in an ineligible form. It seems to be the correct spelling, just jumbled together. I've tried adjusting the fonts, browser acceleration, to no avail. It's becoming difficult to read, and it has only been affecting the desktop browser. It works just fine on my Mac and phone, but not my windows computer. It is the only application that does this. I've updated my drivers and all.

Previously available websites suddenly stopped opening for me. I just get a blank page. I thought it was the VPN so I canceled my account and deleted it. Still not working.

Hey

On sunday 05 july 2026 I was filling in an online form and all of a sudden most of the data I was filling on the form just disappeared. This is really important information.
