duplicate of /questions/1451961 support forum thread.

What does it mean browser not supported by the way I don't like reading so that's why I prefer to talk to a customer care representative

Fix my browser it says unsupported I can't play my casinos my games are nothing not been able to ever since I downloaded Firefox I don't want to go back to Outlook that's why I chose Firefox it used to be a good browser I'm having second thoughts

I recently migrated my Firefox profile from a windows 10 to a windows 11 computer. Everything seems to be working fine except saved payment methods.

My cc info appears when I go to type in card information on a website, but when I click on it and press enter or tab, it disappears. My saved payment methods in settings appears empty, and the add button doesn't do anything.

What can I do to fix this?

Fully patched Windows 11 on ARM Windows Surface Pro X SQ2

What I see: Misrendering of UI elements and some elements of webpages. Rectangular areas of all white with white on white text e.g. tab labels, settings page, etc.

What I tried. Uninstalling FF Reinstall FF Refresh settings

None of these fixed the problem for me.

Uninstalled Firefox Reinstall of Firefox

My system specs is as follows

i5-12400 32gb DDR4 3200mhz 250GB SSD as main (wd blue NVME)

Whenever I play 8k 60fps video on youtube it lags and get massive frame drops with igpu sitting at 100% usage. With other browsers like chrome and edge it works 100% can play 60fps 8k video without any issue.

Since 127.0.0 and now with 128.0.0 i am unable to print readable barcodes from the firefox web browser due to the print quality being so poor, (other web browsers print fine)

I sat down to use PC running MS Win, my Firefox icons no longer opened Firfox. It seems that Firefox was been removed. Problem is, I didn't remove it, no one else has access to this PC. Is MS Win doing this? Any ideas? (Switching to Linux ASAP).

Dear Sir or Madam,

Once again, Firefox is blocking my ability to go into X (Twitter). I'm guessing you guys did an update and changed the settings again. PLEASE FIX. Thank you.

Sincerely, Britt

What's with youtube this week? Earlier there were issues with buffering every now and then, which I've read was google to make firefox users change browser to chromium-based one (chromium browsers didn't had buffering problem). But now videos won't even start to play just buffer endlessly. I've read somewhere that youtube changed something on the server side and now third party apps may have problems playing video. I don't have playback issues on vivaldi or chrome but I don't want to switch browser.

I provide IT support for an 80 year old friend. He uses Windows 7 and Firefox ESR. He has Firefox home as the home page. He had 3 rows of icons showing on Firefox homepage. However today the home page did not show any icons when Firefox was started. Since then about 10 websites have been visited but only 2 show on the home page (Settings Home Shortcuts [for sites saved or visited] is ticked with 3 rows specified. Saved bookmarks are still present as are the saved login credentials.

Any ideas as to why the home page 'lost' all the icons? Why are many of the visited sites not showing on the homepage and how can they be shown? Are there any criteria that apply before a visited website shows on the Firefox homepage?

Thanks for any advice.

I'm not sure why I get this message: "This site isn't currently available in the EU", but only on my Windows 11 laptop. I don't get the message on my cell phone; instead it goes right to the website. They both use Mozilla/Firefox. here's an example: "https://mail.yahoo.com/d/folders/1/messages/AN6WxktugKP1Zo6E-gXQSGxZLg4." Connection button shows that the site is secure. I have not cleared the cookies. When I select any one of the subjects in the email which are usually local news items I get this response: "This site isn't currently available in the EU." Here's an example of one of the items: "https://www.audacy.com/wwjnewsradio/news/local/michigan-man-guilty-of-making-threat-of-msu-stage-act-2?utm_source=WWJ-AM&utm_medium=email&utm_campaign=WWJ-AM%20NEWSLETTER&utm_content=WWJ%20Daily%20Recurring%20Newsletter&mi_u=1655089&mi_ecmp=WWJ%20Daily%20Recurring%20Newsletter."

The problem is I'm not in the EU and it appears that I might be dealing with a tracker but when I scan the computer there is no evidence of that. Is there something else that might be going on?

Mozilla Firefox will not open websites for gooutdoors, millets or blacks, or any linked to the 'blacks' group. Their website addresses are all different but there is clearly some association with the group.

No messages, just a blank screen as though continually waiting.

Used to be ok but this issue has been consistent for at least the last two weeks, and there have been no changes to equipment or software in that time.

Have cleared cache and cookies, and restarted the router but makes no difference.

These websites open ok on my phone, which uses google chrome, so specific to firefox. I use norton 360 on both pc and phone and have done for last couple of years with no issue.

Previous post from around 3 years ago show this issue has occurred for other people in the past and no solution provided, where some reported the problem evewntually disappeared on its own with no explanation, but don't think it lasted this long.

Help please.

I am able to set Firefox as my default browser, but as soon as I close out, it is no longer the default browser.

Another issue I have is that I have a message at the top of the Settings page indicating that some other organization is managing Firefox. I have read all the support notes on this problem, but the one the instruction that I think would work is grayed out so I can't change the parameter.

So, I use Fn + F7 which should stop or play the last active audio source.

Sometimes it works, sometimes it just refuses to work for one site at time, while the others work fine. So, for example, I have site x which plays audio, and site y which played audio some time ago, both windows open. Sometimes medias keys work as supposed, sometimes it doesn't work for site x for no apparent reason while it works for site y, or vice versa.

To get it to work, I have to spam it, move the tab around to the front (sometimes it works, it seems it gets priority, but it could be just coincidence) or completely close the tab and open another one with the same site. Whatever's causing this, it seems to be random, but it seems to be caused the most when having multiple tabs that can play audio, but not exclusively.

I just switched to Firefox and I don't really want to switch back, so it'd be great if any assistance is offered. On my last browser this wasn't the case.

This is what I've tried to solve the problem, but didn't work: - Go to about:preferences and turn off and then back on media.hardwaremediakeys.enabled - Open your Firefox settings (about:preferences); Uncheck Control media via keyboard, headset, or virtual interface. It is at the end of the page; Restart Firefox; Check that setting again

Additional information: - Here's the site that causes me trouble the most (this is a YouTube playlist loader for big playlists): https://youtube-playlist-randomizer.bitbucket.io/ - I use Windows 11

When I enter "about.config" in the address bar, it searches it instead and I can't get to the about.config page. I thought maybe it was the search extension I was using but when I changed it, the problem persisted. Is there a way to fix this or at least a way to get to the page?

Hi, I have a problem with Youtube playback on my machine. Sometimes videos are playing and skipping few seconds, sometimes stopping/hanging and using a lot of CPU (I can hear CPU fan ramping up). It mostly happens when I play videos at 1080p and up. Sometimes video can start playing, then skip few seconds, play few more seconds and hang, sometimes after refresh it works fine, another time it works for like a minute and then again hangs/skips. I had this problem on FF 89, I've updated to 11x, still persisted, now I have FF 125.0.3 (64 bit). Things that i've tried: - enabling/disabling hardware acceleration in FF - enabling/disabling gpu hardware acceleration in Windows - changing some settings in about:config (fe. media.wmf.zero-copy-nv12-texture to false and gfx.direct3d11.reuse-decoder-device to false, and few more) - disabling and deleting addons
