Firefox Support Forum

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.

Radio buttons on some websites neither display nor update when the area in which is should have displaed is clicked. FireFox 113.0.2 (64-bit) on Mac OS X 10.13.6 (High Sierra). This problem has been present for some time. On other websites the radio buttons do display and do upate when clicked by toggling the dark center. The minority of websites which don't work seems random, but does include some banking websites and the IRS.gov website. Often using SAFARI will work when FireFox doesn't.

The CheckBox at the end of this page "Email me when someone answers the thread" appears but does not respond to a click.

For the past few days I get the request to enter captcha characters every time I try to access the Amazon website using Firefox on my Win10 PC. It works fine on my Firefox for android on my phone and also works fine using the Edge browser on this PC.

I've tried resetting Firefox. I've tried troubleshooting mode. I've tried turning off enhanced tracking. What else could cause Amazon.com to feel the need to verify that I am not a robot ?

Hi, Hope you all are doing well. I recently checked my website [removed] on different browsers. Website is working fine with most of the browser, but when i checked it on Firefox i got an error in DevTools "Image corrupt or truncated". What does it mean? This is a category image and present on sidebar of website. But all other images are same, i mean with same size and format. Why exactly this image is creating an issue?

Kind Regards, Hassan Mujtaba

The subject website pge.com has blocked Firefox apparently because new function that they have instituted features that Firefox cannot support. The subject website states it does not support Firefox. Is this refusal to support on the subject website a known problem? I have searched the Firefox Help without results. Is this even considered a problem? I appreciate Firefox and would like to see it be a supported browser on the subject website.

I got this issue when tried to read some API document provided by a marketplace that i have project with. I tried on another browser and it shown normal, not a single text is overlapping. I've tried some suggestion on another topic to pick No Style on Page Style menu (View -> Page Style -> No Style) but it got more messed up and tried changing font size but still got no improvement. Helpp me pls~

When I open "Wheel of Fortune" and click on "Log-in", nothing happens. I am unable to log-in. Using another browser, I have no problem.

Anyone with a suggestion or solution for me?

The layout on the Roblox website, https://www.roblox.com Has appeared to break, I've seen the website on Google chrome and Microsoft Edge and it's good to go. I am not aware as to how this has happened. I have disabled every Addon I have, This issue is not caused by the Addons I have installed.

CTRL + F5 has Fixed My Issue! Thank You cor-el!

In the last week or so, iPlayer, All4, and Spotify (that I know of) have stopped working in the Firefox browser. All4's error suggests DRM isn't enabled, the others just say try again. Roll20 hasn't been working for even longer (more like months). They work in Microsoft Edge and Chrome. Youtube is still working, as are video players in social media.

I have tried the following solutions:

• Firefox is up to date
• Windows is up to date
• Updated graphics drivers
• 'Widevine Content Decryption Module provided by Google Inc.' is set to 'Always Activated' and is up to date
• 'Play DRM-controlled' content is ticked in about:preferences
• Checked if anything changed if either of the above were turned off (it did not)
• media.eme.enabled is set to true in about:config
• Put Firefox in troubleshooting mode
• Turned off my addons (including uBlock Origin) manually
• Tried in a Private Browsing window
• Turned off Tracking Protection
• Restarted my laptop

Nothing has fixed the problem, or given me any more indication of what is wrong. I don't know how to a) fix or b) find the problem. All I can think is that it may be related to the recent changes to Chromium regarding ad-blockers? But no one else seems to be having the same problem so I doubt it.

When I copy text from other websites, I'm not able to paste in the text field of Whatsapp Web. I'm using Firefox Developer Edition Browser in my laptop. But when I copy text from Whatsapp Web itself, I am able to paste in the text field.

This issue started happening just a few days ago.

Here are my specifications:

Browser: Firefox Developer Edition 117.0b8 (64-bit)

OS: Pop!_OS 21.10

Hello, since 2 weeks I have some plugin who are not displaying in my wordpress dashboard and they are working normally on Chrome. This morning I got this message: An error occurred while connecting to WordPress REST API. It seems blocked by one of your plugins or your theme. Thanks for your help

• The attached image shows Firefox (on the right) not displaying Helvetica correctly. It appears jagged and not pleasant to look at. The browser on the left is Edge and all Chromium based web browsers seem to render it as it should.
• I've tried to look into (about:preferences#general) and the option that says (Allow pages to choose their own fonts, instead of your selections above) is ticked.
• I've also tried reinstalling the browser, clearing the website cache and also, removing my profile from it. None of these seemed to fix the issue.
• It's been persistent for quite some time now, however I didn't really find any articles regarding this issue.

  Any help would be greatly appreciated!

Hello everyone. I do not know if any else has experienced this but I have several websites that I cannot sign in to. I have no problem reaching the sites but when it comes to signing in I either get a message that my sign in information is not correct and this happens on Bestbuy.com or I get this message on Chewy.com Access Denied You don't have permission to access "http://www.chewy.com/app/login" on this server. Reference #18.88dcda17.1684871617.2bce7d64 . Now if I use the awful MS Edge I have no problem signing in to either one. I have racked my brain to figure this out even disabling each addon which I only have a few. I have ran scans for Malware with Norton 360, Malwarebytes and MSERT and nothing there. I was hoping someone could shed some light on this in some way or maybe change a setting in Firefox that I am overlooking. I can access these sites fine and move around in them but like I said I cannot sign in into them. I would greatly appreciate any help.

Respectfully, DT

We've noticed that in Firefox 112.0 (maybe in 111.0? haven't tested yet...) when a `fetch` request with an `Authorization` header gets a `302` (or `307`, and probably any other redirect response code) and `redirect` is set to `follow`, the second request is made _without_ an `Authorization` header, which breaks our website.

In 110.0 this isn't an issue, and no warning is logged to tell us it's about to change.

I'm guessing this is a security change - could someone point me at the discussion that led to it being made? My feeling is that if the redirect is to the same origin as the original request sending the same `Authorization` header should be secure enough.

I'm wondering what the right mitigation is; we could follow redirects manually of course, but it's a pain.

I must've accidentally pressed a button last night while I was watching a YouTube video on my desktop, as now the right and bottom edges are cut off when the video is in standard mode. Refreshing hasn't fixed the issue, neither has restarting or shutting down my laptop, as it was turned off for 12+ hours and I still had the issue when using YouTube today. It's even an issue in incognito mode, but not an issue if I use a completely different browser. I can't find anything else that has been affected by whatever button I must have pushed. Laptop is a Dell G15, if that's relevant. Would love any tips to fix this.

One particular website that I login to frequently in Firefox suddenly stopped opening the login screen when I click "Login." It opens in Safari and Tor browsers, but not Firefox. How do I get the login screen to appear? I have disabled enabled Pop Up Windows for this site, but it still won't load the login screen. It works in Troubleshoot mode. What does that mean and how do I get it to load the login screen in normal mode?

When I try to log into Google I get this message:

This browser or app may not be secure. Try using a different browser.

I am using Firefox 91.13.0 ESR (64bit). I have been using the 91.x ESR releases for a while now and this is a new problem that I never had before.

Having any google related webpage open for more than a couple of minutes causes it to disconnect (gmail, calendar). This results in no connectivity to any Google services. Opening new tabs will refuse to load even Google.com. The only fix is to completely close out of Firefox and relaunch. But having gmail open for a few minutes will result in it disconnecting again.

The issue persists in 'troubleshooting mode' as well as after doing a refresh. I have experienced this now for the past couple of weeks on my Windows 10 work laptop. I have also seen this on 2 different Linux machines in the past few days. I had attempted to disable http3 and telemetry settings from an older post I had found, but no luck. Not sure what else to try at this point.

I tried to access my Amazon Music account with Firefox v102. I received a message from Amazon that says "Update Firefox - We have upgraded and this browser version is no longer supported. Please update your browser or download our desktop player." when I try to access. I've deleted all cookies and history. I've tried with no add-ons (safe mode). Nothing seems to help. I'm running Windows 10 (64bit) build 19044 on a Thinkpad with 16GB RAM and 1TB SSD.

Amazon music works fine with any chromium browser. Is this another big-tech effort to clear out their competitors? I'm not going to download any application from these big-tech overloards!

Thanks,
