After upgrading firefox to 110.0, WhatsApp web failed to load. I refreshed the browser also as I found one solution on forums, but after QR code came but failed to load the chat.

Firefox stopped working with my VPN on when I updated my OS to Sonoma, yesterday. I use PIA for my VPN.

I have done the following, so far, restarting my system several times between trying these things:

Checked that internet connection and modem are fine. All pages load in Safari, with VPN running, but I prefer Firefox.

Checked the Network settings for my Mac. Ensured that No Proxy was selected.

Cleared my Firefox cookies, cache and history.

Tried running in troubleshooting mode, turning off all extensions.

Tried turning off Advanced Tracking Protection, which I usually run on Custom.

Refreshed Firefox.

Finally, I turned off my VPN and, viola, all sites work. Turned it back on, and can’t navigate, again. For instance, I tried to open YouTube, and got a blank screen. Turned off VPN, and got to main YouTube page. Turned the VPN on and tried to log in…nope. Turned it off and logged in. Turned it back on and tried to open a video….nope. Turned it off and opened the video…etc., etc..

I very much wish to continue using both Firefox and my VPN. Can you suggest a course of action? Thank you for any advice you can give!!

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

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

Hello all,

For some reason, I can no longer upload or download files, with the pop-up window failing to appear entirely. I can upload folders through, for example, Dropbox or Google Drive, but individual files don't work.

I've reset my browser, uninstalled and reinstalled it, opened it in troubleshooting mode, disabled enhanced tracking protection, but nothing seemed to work. I've tested another browser, and I was able to upload and download files just fine.

Is there anything I can do to fix this? I'm on Ubuntu 22.04 using Firefox 107.0.1.

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.

Starting yesterday, every youtube video I try to watch never plays or is in a constant state of buffering. It works fine in Edge, and Twitch streaming has no issues so its definitely not my internet connection.

I've already tried clearing my cache, rebooting, clearing it again and refreshing Firefox and the issue remains. Disabled adblocker as well. I am currently on version 106.0.5

Since yesterday (Sep 26 2023), Twitch.tv has been having multiple issues related to basic functionality of the website, and this has happened before but I did not report it because I was able to fix it. I can not purchase or use bits despite Twitch having a stored payment method on file that I have confirmed has sufficient funds, I can not subscribe or gift subscriptions despite Twitch having that same sufficiently funded payment method on file, I can not redeem or earn channel points, I can not send or receive Twitch Whispers (a form of DM), I can not follow or unfollow channels, and I am convinced that if I was to log out, I would not be able to log back in. I can chat in stream chat, and I can watch streams, that's all I can do. But I enjoy using the other features that are currently blocked, I am over 18, and I am the only person that uses this computer, so there should be no parental controls problems either. Yesterday, I restarted my browser, which did NOT alert me that it had updated, and all of this functionality was broken. Roughly 6 months ago I was having the exact same issues, but I was able to fix it by disabling many of the anti-tracking protections on my browser (had to disable them universally except for blocking cryptominers, not just with the shield icon). However, now, even with those settings unchanged, roughly 75% of the features of the website Twitch.tv are nonfunctional. I have included a cropped screenshot of me attempting to redeem something using channel points, the purple box is the button, and the spinner icon stays there for over a minute with nothing happening, which is not how that is supposed to work.

I enjoy watching streams and interacting with people on Twitch.tv, and I wish to continue doing so in the way I am accustomed to. However, it would appear that Firefox has other plans. If this continues, I will be forced to switch to a less secure browser for specifically that site, which is an idea I do not look forward to.

Just today, I can no longer access the Amazon website. The pages load halfway and then it just churns/spins and never completes loading the page. So far I've discovered no other websites that have the same problem.

I am able to access the Amazon website on three other browsers - Edge, Brave and DuckDuckGo - with no problems and normal loading speed. I don't use Chrome, so I can't speak to that.

I've tried clearing the cache and that did not help. I had a Firefox update installed a couple of days ago. Don't know how long it had been sitting there, as Firefox is almost always open and doesn't have the opportunity to update until I close everything and restart my computer, which I did a couple of days ago.

Windows 10 on a Dell pc/laptop. Firefox Version 126.0 (64-bit).

Any ideas on how to fix?

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.

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?

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?

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

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.

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.

Hi,

I use Firefox daily, but since the last update I'm unable to make card payments on websites and I'm having to use Chrome as a backup. Up until the update everything was fine and there were no issues making payments on the Royal Mail and Asda websites. When I click the pay button on these sites, the payment window does not open up.

I've tried disabling all addons/extensions to no avail.

Regards Andrew

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!

Hello, everyone.

4-5 days ago, I've noticed weird YouTube playlist behavior. When I start playlist and switch to a different tab (or minimize browser) first video will play normally and it will autoplay the next one. But after finishing playing 2d video (3d in some cases) video will just stop at the end of playbar and not autoplay the next one in playlist. Playlist for example: https://www.youtube.com/watch?v=giUY_pEKTzY&list=OLAK5uy_nKmglmCCbx14WeFyH8e7YGYcL5skYwnp0&index=1

It's rather easy to replicate, I can record desktop video if needed.

Expected behavior: I can start YouTube playlist playing and switch to a different tab or minimize browser and playlist will only stop after playing last video in said playlist (unless "Loop playlist" option is enabled).

What I've tried to do so far: 1) Googling: I only was able to find old thread and the culprit was extension: https://support.mozilla.org/en-US/questions/952608 2) Disabling Extensions and confirming issue in Troubleshoot Mode: Did not help 3) Clear cache & cookies for YouTube: Did not help 4) "Allow Audio and Video" autoplay for YouTube: Did not help 5) Confirming issue in another browser: Works as intended in Opera 6) Checking about:config: I'm not that savvy with Firefox config to understand what may cause an issue. Tried to change media.block-autoplay-until-in-foreground to False. Did not help, rolled it back to True.

What I have noticed: 1) Firefox recent update: 118.0.2 October 10, 2023: Correlates when I started experiencing this issue. 2) YouTube playlists plays next video continuously just fine if I don't minimize browser or switch to a different tab. 3) There is a Firefox extension that does exactly what I don't want in my experience: https://addons.mozilla.org/en-US/firefox/addon/no-playlist-autoplay-for-yt/ I installed it just to check. And yes, it does what expected and it is similar to what I'm experiencing. Although it stops playlist after finishing first video, my issues go into the affect after playing first video. (Deleted it after testing)

Before posting I've tried a few different things and here where things gets extremely weird: 1) It works just fine in Firefox if I log out from my YouTube account: (Incognito/Main tab) Do not work if I'm logged in, even in Incognito. However... 2) It works just fine in Opera if I'm logged in my YouTube account. 3) It works just fine if I open playlist in mini-player. (Current workaround)

After all that weirdness I attempted to Clear cache & cookies for YouTube and it did not help once again.

P.S. Yes, I use YouTube as a music player. :)

Dear Technical Support,

I'd like to report a problem which affects the rendering of websites in Firefox with a HiDPI monitor.

I'm having issues with the text and graphics of web pages, that are often mismatched or misaligned, with text being too large compared to graphical elements. See the enclosed pictures for an example; as you can see, this happens also on your website. Also, I've noted that pages (and plugins) appear to be "shrinked" as opposed to when viewed on Chrome, where they are shown to their true size.

Setting ui.textScaleFactor=100 and tweaking with layout.css.devPixelsPerPx did not change much. I must admit that I find this behavior quite strange, since HiDPI monitors have been around for more than a decade, and especially considering that this did not impact my experience with Firefox on Windows, using the same monitor and machine.

I hope to find an effective solution to this problem and look forward to your reply. Please let me know if I can be of any help in this matter.

Best regards, Federico
