Hello I was listening to a song from amazon music premium like usual but today the website updated and somehow it said the browser didn't support high quality songs... It didn't show it, but it seems it never supported hq music, is there a way to play it on the best quality or is it a limitation on firefox's part? How can I fix it if it's just an error?

"Browser does not support HD quality"

On my Mac with current OS X update, Firefox is great except for one website: kaiserpermanente.org - it will not respond. Attached is a copy of the Firefox response page when I try to login, or ask about cookies, or anything besides their home page. PS, everything works perfectly on my i-phone.

Thanks.

I get PR_END_OF_FILE_ERROR when trying to load certain websites. I don't use any proxy or VPN, I tried disabling DoH. Also sometimes i get 403 forbidden cloudflare.

Why is Firefox Browser no longer an acceptable browser to access some on-line accounts? Business entities are no longer recognizing Firefox. When utilizing another browser connectivity is no issue.

When previewing an image that was uploaded to a Google Calendar Event, I get an error "Couldn't preview file. There was a problem displaying this image." I've spoken to Google support and they suggested I reach out as when I try in Chrome, it works. Firefox is my preferred browser so I would love if I didn't have to switch to Chrome.

Troubleshooting Done: - Verified Firefox is up to date (130.0 64 bit) - Cleared cache and cookies, closed browser, reopened - Tried in 'Troubleshoot Mode' - Ad Blocker turned off - Uploaded test .png and .jpeg to see if it was a file extension issue - Uploaded smaller versions of images to see if it was a size issue - No issues when doing same steps in Chrome browser

Cannot get into Firefox as of 3 hours ago. Error message see screenshot below. Hope you can help as Firefox is my default browser.

Good afternoon, In my extensions, I use Cozy Pass. But since weeks ago, Cozy Pass is in grey, not blue as usually. When I try to connect there is this message: " Une erreur est survenue. NetworkErrorwhen attempting to fetchresource" Can you say me how to resolve this problem. Best regards Patrick

Every time I have to restart the microsoft nightmare called windows 10, the 1st time I open Firefox it opens in a half screen window on the right side of my screen. It's set to open maximized and run as administrator but still won't do so immediately after a restart. Is there a fix for this?

Hey, I just recently started using Firefox, and I've started to notice some odd behavior. When watching videos and reels on Facebook (Desktop version), videos will flip-flop between normal and really bright and washed-out. I'm currently on Firefox 130.0 on Windows 11, and I always have HDR on. The imagery is silly, but these two screenshots (using win-shift-s) are from the same video only seconds apart, and this happens on almost all of them. Not yet tested to see if it also happens on Youtube or Twitter videos.

Hello all, I recently made the change from chrome to firefox and have been loving it so far. The only issue is; when I have a youtube video open while playing minecraft, the video lags and the audio skips. It never buffers and I have a great fibre Ethernet connection. When I try on chrome it doesn't happen. Only on firefox.

Lately I have been having some real problems with Firefox. PG&E (Pacific Gas & Electric) does not support Firefox (I get a message telling me that Firefox is not a supported browser and I need to use Chrome, Edge. I also am having problems with sites like Petsmart where I keep getting logged off and nothing actually ends up in my cart. I don't like Chrome and I won't use Edge under any circumstances. What is the problem that these sites are having with Firefox? I have been using Firefox from it's first being offered (yes I'm that old) and I don't want to change. I use DuckDuckGo with both Firefox and Chrome so I'm reasonably certain that the issues I am experiencing are Firefox issues. I have tried turning off the add blocking extensions and even my firewall but that hasn't helped. I get the feeling that these sites (and others) are part of an effort to get rid of Firefox in favor of the 2 giants Google and Microsoft. Am I just paranoid or what?

I use Windows 10, McAfee Security software, Firefox browser with DuckDuckGo search engine. I also use Chrome browser with DuckDuckGo search engine. Everything works fine with Chrome.

When I go to bcbsm.com and look at my EOB's...it is a pdf and a lot of information is missing, but if I switch browsers (Chrome) all the information appears. How can I fix this?

About a month ago, firefox stopped remembering a download location, it's only on one website though. I can download from anywhere but there and it remembers the location but it won't from that site and that's where I download from the most.

This was ALSO occurring BEFORE I switched to ESR, in both types of windows (Private & Standard):

A click to open a website link results in Firefox doing a runaway, unstoppable, rapid opening of tab after tab after tab. The only way I have found to stop it is to close Firefox entirely, losing the tabs I was working with in addition to the runaway tab openings. Any solution?

Windows 11 Pro Firefox 128.2.0 ESR (also behaved in same way using standard release version, as well as ESR)

The amount of memory firefox takes is drastically higher (2GB + tabs and extensions) on Apple Silicon when compared to having the same tabs open on windows or linux.

When I look into the memory tree generated at `about:memory`, it seems that the `heap` is allocated nearly 1.5GB.

I am just a computer science student at the moment but that seems unusual to me. Please find the attached memory-report.json.gz file here

I was enjoying using firefox. It has only been 2 days since installation after which it started lagging. It lags only while scrolling pdfs, youtube. All other animations are working fine. Only problem is in scrolling it.
