So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

Hi. Strange request I know because Firefox is working perfectly but Google has failed me.

We have a printer/copier in our small club. The IP address assigned is 192.168.1.125. Typing this into a browser should bring up the copier admin dashboard.

When I do this using Firefox everything works fine, BUT when I use any other browser such as Chrome, Edge or Opera I get the "Cannot connect" "Error connecting" etc message.

I removed Bitdefender antivirus and disabled Windows Defender but it's still the same.

Any network people who can point me in the right place as to where to look or report to the correct forum.

Apologies for posting in here when it's not a FF problem.

Thanks in advance TQO

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

I always want the address bar suggestions to start with my bookmarks. Is there a way to control the results? I remember there was something in about:config previously.

I've been having problems with some websites not displaying content, others displaying error messages. So have been going through the Troubleshooting Mode and diagnostic process.

The cause is the MS CoPilot extension for Firefox.

Useful in other ways as I discovered several other extensions I don't need, hence have remained disabled.

This has been happening for about a year now, I followed the guide and tried the troubleshoot mode and my tabs still crashes.

Can anyone help me read the crash reports and find the cause or common issue?

Here are the most recent crash reports I submitted.

I am unable to reach Facebook on both Firefox and Waterfox.

Other browsers (Opera, Edge, Chrome) are able to access Facebook.

I can access other Meta-owned sites (Messenger.com, Instagram, Threads) on Firefox and Waterfox.

This issue exists on both my desktop (Windows 10) and laptop (Windows 11).

This issue does not apply to Firefox for iOS or the Facebook app.

All apps and OS's mentioned are up to date.

This has been going on for over a week now.

Several instances of this "verification.exe" malware appear on download history when firefox is opened as shown. Remove from history or clear downloads doesn't eliminate them. They reappear whenever firefox is opened.

Suggestions to eliminate this nuisance welcome.

I reset a computer, deleting all my files. I want to use, as I do elsewhere, Firefox as my browser. And though I signed into Firefox using my old credentials, none of my bookmarks are there. How do I complete this setup?

Urgent Help Please as lost ALL EMAILS - I cannot get to post in Thunderbird: 1) I've now spent 4 hours, (from what was trying to sort a 'simple' problem on the server), as I couldn't send or receive any emails, as they think I've 6.5Gb of data on it, in spite of my deleting all my emails off it. So they allowed some extra space to temp sort it again. It's been an issue for about 3mths now. But I deleted everything just the other day having confirmed that was not deleting them off my laptop and that the previously lost emails 2 yrs ago weren't still on their server.

But now checked back on my email client Thunderbird, and I've no emails. They're all GONE bar the odd few I've put into folders (I stopped using folders years back as that lost all my emails way back then!), so I'd been keeping them all in the Inbox. Although I've a few old Inbox files with previous old old emails in so I can access them if I need to. But at least their there! But now again I've just lost everything. This is such a disaster.

Over the last 2yrs it's been going OK until today. Now it's LOST ALL MY EMAILS. I'm as per usual up to my eyes and have to travel this friday for meetings next week. The last thing I needed today was this. I've lost so much data and info in those emails it's doesn't bare thinking about. From show tickets that I need, medical info and data, to flight details to all sorts of crucial data. My ONLY saving grace is that anything I've replied to, I have a copy in the sent folder.

So Please Forgive this being in Firefox, as I can't even add it to Thunderbird help area!! I've had to reset my pw too just to sign in. Sadly right now it all feels so very upsetting I'm thinking I'll have to just have to start using another email client! If every 2 yrs I lose all my emails then this is just not acceptable. I hope you can move this to the Thunderbird threads. If you do please send me a link to it so I can try and find it.

What's so upsetting is had I saved the Inbox file when I saw the 13Gb file size, a bit eariler then, I think I could have saved them. I fear though that the remote server people deleted something, that was somehow still linked to my system and that's meant they've deleted my emails off my laptop too! Terrifying! (Perhaps that is what happened before back in '22. ???) I did look at a 'Sync' settings but not sure what they did so cancelled back out of them.

Running on Win 10 Pro 64Bit i7core 8Gb Ram Thunderbird 115.10.1 (64-bit)

Any and all help will be most gratefully received.

Sub issue to get help : 2) Error to Sumbit to Thunderbird: Sadly I've gone around and around your system saying Ask Question when nothing answers my query on the Thunderbird email questions. But when you click on Ask Question it just takes you back around the system again / Browse all Programs / re click on thunderbird/ reclick on Emails and back to list of FAQ's but nothing helps so click on Get Help and back around you go in a deja vu system.

I am using Firefox version 125.0.3(64-bit). I am not able to access my saved passwords. It is asking me to log in when I am already logged in to my Firefox account. When using Firefox in Troubleshoot Mode I can access my saved passwords. How do I solve this problem? Moreover I am unable to add a Primary Password to protect my saved passwords. I have never tried to add a primary password before this problem.

I am running the latest updates to Windows 10 Pro x64. One of my monthly bills is paid at

1) https://e.synchronyfinancial.com/

which, in Brave, redirects to

2) https://lowes.syf.com/accounts/login

Inputting either link in Brave gets me to the finish line but the first link above fails in Firefox with the "Secure Connection Failed" message and dumps me at https://www.synchrony.com/accounts/. The second link does the same.

Is there any way to troubleshoot the problem?

I HAVE tried shutting-down Malwarebytes but the result was the same.

This is the only site on which I have encountered this issue. All that I can determine at the moment is that that certificate is from DigiCert and the expiration date is in 2025, i.e., this is not a Symantec cert.

I don't use Google Chrome browser nor do I use MS Edge. After using the Mosaic browser, I switched to Netscape Navigator, then to Mozilla, and, finally to Firefox. I am not looking forward to migrating to another browser. ;-)

When I went to start firefox today on my MS Windows computer, I got a file error message saying pathway was corrupted (or something like that) and then the firefox app disappeared from my pinned toolbar. When I went and reinstalled it, all of my saved bookmarks and passwords were gone. How do I get them back?

Firefox just will not print anything at all. I have tried all the suggested fixes; everything else on my computer prints fine to either directly connected printers or to network printers. The 3 other computers on my home network all print to all printers from Firefox. I have deleted Firefox and reinstalled I have deleted all printers and reinstalled When I do try to print with the print queue open, the file spooling briefly splashes up and disappears quickly. If I download a PDF from the web, it will not print from within Firefox, but will print from Acrobat or Nitro I have changed antivirus from Eset to Webroot anywhere. No improvement and in between with no Antivirus, Firefox would not print. Any thoughts, as I had to change browsers and I want to get back to Firefox? Help!!
