Over the past week or so, Youtube videos take a while to start, and will at times just stop and buffer. I turned off uBlock Origin for Youtube, and I have Youtube Premium, but this issue is still happening. Ookla speed test is 569.32 Mbps download, and 23.50 Mbps upload. My Firefox is set to automatically update. Current version is 127.0.1

Twitter's login page won't load when I try to open it in Firefox. https://twitter.com/ https://twitter.com/ loads just fine, account pages like https://twitter.com/firefox load just fine, and individual tweets individual tweets load just fine. But when I click the login button on any working page, or go directly to the login page at https://twitter.com/i/flow/login, all I get is a white rectangle in the middle of the screen that flashes a loading-spinner for a few frames every two seconds but never actually loads any page content.

I can log in just fine in Chrome, so the problem is specific to Firefox. The problem started at least a week ago, but I don't log in on my desktop regularly enough to know exactly when the problem started.

I turned my Browser Privacy setting to "Standard" and cleared all site data from Twitter, with no effect. I use uBlock Origin, but the problem persists when I disable it. The problem also occurs in Private windows.

I've been watching and following along with a Unreal Engine 4 Course on Youtube for some time now (mentioning in case the resource usage has something to do with it), and in the past couple days I've noticed a pretty serious and annoying bug. When I pause the video, tab (Cmd + Tab on MacOS) into Unreal Engine, do some things, then tab back and resume the video, it will play for one frame and then stop and buffer, but the audio will continue playing. The only way to get the video to resume is to skip forward/backward in the video (either with the arrow keys or the progress bar). I've also tried Troubleshooting/Safe mode and the issue still persits.

Hi! I'm using Firefox 126.0 on Fedora 39.

Pages from Amazon.co.uk load very slowly, incompletely, or not at all. All other Web sites are fine.

I had a couple of certificate-related errors saying that the identity of the site couldn't be verified, but I can't reproduce the problem, so I can't quote the exact wording, I'm afraid.

The same Amazon pages load properly in Chrome on the same machine, and they load properly in Firefox in a VM on the same machine. That tells me network connectivity must be fine.

I've tried disabling all extensions, reverting to the default theme, running in Troubleshoot Mode, clearing cookies and site data, clearing the startup cache, disabling hardware acceleration, and creating a new profile. The new profile helps slightly, in that it loads more of the page before getting stuck. Nothing else helps at all.

I'd prefer not to refresh Firefox if I can avoid it, because I don't want to lose all my plugins and settings. This installation is five years old. Besides, a new profile didn't fix the problem.

What's the next thing to try? I'd really appreciate any ideas.

I am trying to sign into my bank accounts per usual this week and am encountering the above issue. I feel like I have tried everything. I can sign into the account on Safari, Microsoft Edge, or the on phone app just fine. I did not have this issue last week. To date I have tried: 1. Clearing cookies and cache 2. Forgetting the website 3. Turning off all addons/plugins 4. Changing theme 5. Uninstalling and reinstalling FireFox 6. Refreshing FireFox 7. Turning off fingerprinting 8. I do not use a VPN 9. Tried using incognito mode 10. Tried using safe mode

Please help. This is so frustrating. It is not on the bank's end as others can sign into their account just fine from Mozilla Firefox. It is not a computer issue, because I cannot sign in on either my laptop or my computer. I do have my browsers synced across machines, but I have tried logging out and signing in again to no avail.

When a playlist is loaded and played on YouTube, the next video in the playlist should automatically start playing once the current video reaches its end. This feature is commonly known as autoplay. However, I couldn't get it to work consistently. When the current video is finished, next video is loaded normally but where it should automatically play it doesn't.

I have tried below to address this issue:

• Autoplay next video works in safe mode.
• "allow audio and video" in autoplay permissions in https://support.mozilla.org/en-US/kb/block-autoplay doesn't help
• I have also set media.block-autoplay-until-in-foreground preference to false in about:config but didn't help
• I have tried uninstalling all extensions and it didn't help
• Tried logging out of youtube, but this didn't seem to help with the issue.
• Tried "Clear startup cache" in "more troubleshooting information" menu, didn't help
• Tried "Refresh Firefox" which didn't help

Thank you.

Since this week I have been unable to access flightradar24 web site due to a problem with WebGL. It tells me that I need a compatible browser e.g. Firefox

I am running Linux Mint 21.3 Cinnamon on and I7 processor with a NVIDIA Corporation GK208B [GeForce GT 710] graphics card.

I have edited the about:config file as follows:

webgl.force_enabled TRUE

but noted a collection of failed messages as shown on the attached screen shot.

This web site is still accessible using chromium on the same computer, suggesting that there isn't a hardware problem.

Thanks

This problem exists ONLY on Firefox. I vary search engines, from DuckDuckGo to Presearch and Startpage depending on the search results I get.

For no apparent reason I will get a "suspended connection" message on Startpage while using the Firefox browser. I have included both the link and a screenshot of the problematic page. The page will open perfectly several times, and then suddenly, in the same session, if I open a new Startpage tab, this message will appear. While the suspended connection message is visible in Firefox / Startpage, I will try Startpage in Edge, Opera, Chrome and Midori, and they all open to the Starpage beautifully.

I am using the Firefox 125.0.3 browser, I have cleared caches and cookies, and run full malware scans, with zero negative results, and yet this problem persists. It is sporadic, and does not occur on a predictable basis. It occurs whether the Mozilla VPN is on or not, and switching from on to off or off to on changes nothing, even after refreshing the page.

I am assuming that this is a Firefox issue, as the problem does not occur on other browsers

I can easily switch browsers and / or search engines, but Firefox in conjuction with Startpage is my preferred combo. I just find it frustrating in that I cannot fix it myself.

So....Ehhhh...what's up doc?

Hi! I was wondering why nearly every single page these days opens to the message :

"400 Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. Apache Server at canvas.instructure.com Port 80"

Nearly every link I click on a website refuses to open! It has become impossible to do school work on this browser because I can't open any link on my school website, and nearly every website struggles to open except from google. I know the links work because I copy/paste them into Google Chrome and they open immediately. Truth be told I prefer Firefox and would much rather keep using this browser! I also can't find an update for Firefox so I believe my Browser is up to date (and I know my laptop is up to date and virus free). Is there a fix coming soon? Or a setting I can change to be able to open links? Classes start this week and I'm stuck!

Thanks for your help!

I'm not sure how this happened, but one of my firefox web pages keeps zooming in only on one website and the zoom refuses to reset no matter what I do.

For reference this is wikipedia. Every time I load a wikipedia page it loads zoomed in to 210%, which I will then have to reset to 100% in order to read the page properly. If I for some reason click on a link on the wikipedia page that goes to another wikipedia page, the zoom will reset again to 210%, which I will then need to reset once again. This happens also whenever I switch from the wikipedia tab to another tab and then switch back again. I do have an addon that changes wikipedia slightly (the Wikipedia Vector Skin addon) but disabling this addon doesn't fix the issue.

I went into about:config several times already and changed different settings to try and make it stop, but nothing so far has worked. I've tried resetting layout.css.devPixelsPerPx to 1.0 and back again to -1.0 and it makes no difference. I also tried changing browser.zoom.full to false and it keeps happening. Changing browser.zoom.siteSpecific to false does fix the issue, however it also resets the zoom I have on other websites that I want to keep, so it's not an ideal fix. I also cleared all my cache and cookies and it changed nothing.

Does anyone have any idea on why this keeps happening only with wikipedia, and how I can get this to stop happening? I assume there must be some internal setting that would need to be reset in order to fix this, but I don't know how to do it or where I would even go.

Hello For a few days now, every time I go to youtube the page appears almost completely blank (see screenshot). I've tried disabling all my extensions and go in troubleshoot mode but it still does not work. When I try removing youtube storage from firefox settings "manage cookies and site data" and saving, data of the same size is still there when I open the storage manager again. The only thing that seems to work is going into a private window but since I have to keep signing in each time it is painful especially with google MFA. Please help.

Thank you

I have had 2 sites produce this error box in place of the target Web Site (See Picture). I have read previous topics about this and have followed the instructions with no positive results. FYI, clearing the web site's cookies, clearing Cache and disabling Hardware acceleration.

The first was https://www.walmart.com. After leaving a "Feedback" 2 weeks ago it appears as if they were able to fix the problem. However, the site is not as important as my Medicare PPO provider. I tried loading previous versions of Firefox, but that did not help.

In both instances the LOL "support" people's response was to try a different Browser. So, I reluctantly loaded Google Chrome and it worked perfectly. From my perspective, this eliminates everything to do with my machine setup.

Below is the sign-on URL (not unique to me). Please note that this 668 character URL has not changed for over a year. It is just Aetna's adoption of the Imperva Security Firewall. Both my Winders 8.1 and Winders 10 machines produce the identical results.

Hello!

Started up Firefox today and these whited out boxes started appearing over my search bars and random part of the screen, such as the descriptions of different articles on my home pages, extension and theme information in my settings, and different tabs (see pictures 1 and 2). The text is also white, making it almost impossible for me to see what I'm typing or selecting in the search bar (picture 3).

I've already tried some tips that I found on the forums such as changing the hardware accelerator, making sure my extensions and add-ons were up to date, etc. When I go into troubleshooting mode, the boxes disappear and Firefox functions normally, but when I tried turning off all my add-ons and themes on the regular browser, the problem still wasn't fixed. I did a full refresh of the browser, hoping that would help to reset whatever was causing the issue, but that didn't help either.

Any advice or troubleshooting tips would be greatly appreciated!

I have tried watching videos through chrome and other browsers by searching something via duck duck go and watching that video on duck duck go, and it works on other browser so it must be specific to firefox.

Whenever I try to watch a video, in the drop down bar firefox select to mute audio for some reason. I then select 'allow audio and video' and refresh the page but the video is still muted for some reason. This also happens when I try to use other video sites. This has only started to happen recently in the past two days (and yes I am updated to the latest version of firefox).

I'm trying to use Microsoft Teams in Firefox because the native app for Linux is abandoned and crashes, and at first sight the app is blocking Firefox on purpose. Buttons to make calls are disabled, stating that audio and video are not supported in my browser, but everything works normally if join to existing calls using e.g. links.

Is it possible to trick Teams to think I'm using Chrome? I found the "User-Agent Switcher and Manager" add-on, but I can't figure out how to possibly use it.

On both my old laptop and a new one (so a new installation of Firefox), I'm unable to load Frontier Airlines' website (www.flyfrontier.com) and get a time-out message:

The connection has timed out

The server at flyfrontier.com is taking too long to respond.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

This happens even with all of my extensions disabled, with enhanced tracking protection turned off for that site and with HTTPS-only mode and DNS over HTTPS disabled. It also happens when using Firefox in safe mode. Safari loads the same website very quickly and with no problems. Does anyone know what might be going wrong? Thanks.

YouTube is blocking playback on Firefox due to my use of an ad blocker. However, playback is not blocked in the same circumstances when I use Chrome. Are they trying to stop me from using an ad blocker or overturn my browser choice by forcing me to move from Firefox to Chrome for playback with an ad blocker enabled?

this is definitely a unique issue i have not ever had, LOL

i'm running into a very strange issue where only the roblox page is not loading properly. everything else seems to work just fine; trying to load roblox on google chrome works fine too! ive turned off my extensions and run it in troubleshoot mode, i've updated the browser and my pc and my drivers, nothing seems to want to fix it. i'm not very sure what's going on. it's very funny, but definitely troublesome- the website is not navigatable in this state.

it randomly popped up like this last night, i was under the impression roblox itself was down because my friend in the call at the time had been talking about how slow the site is. upon digging deeper and asking around, nobody else is having the issue i'm having so i'm lead to believe its a me issue

Hi,

On https://replit.com/login, no captcha is visible, and login in says "Your captcha token is invalid. Please refresh the page and try again.."

I tested with LibreWolf 128.0.3-2 and FF 129.0.2.

With Chrome, it works.

As of recently, every time I try to watch someone on Twitch, where the video feed would normally be is the streamer's offline banner image. Chat is working fine, and is active despite the stream not being displayed on my end. If I check the Twitch mobile app the stream displays as normal, so I know they are currently streaming. I tried disabling all of my add-ons and restarting the browser to no avail. I am a noob, so please be patient with me. I have attached images of an example, but this happens with any live channel, not just ones I am following (I do not have any active subscriptions as far as I know).
