Firefox Support Forum

Starting yesterday firefox, no recent updates etc, gives a 403 error for several large corporate sites and 404 page not found for most paypal payment pages. These sites/pages work fine with Chrome. There were no changes by by myself to my firefox installation, not any antivirus changes.

Within the last hour today everything is working properly. What is going on? jn

I've had this issue ever since switching to a new laptop. This issue is specifically within Firefox (I have tested this in other browsers and programs, and the issue isn't there. Everything else works perfectly fine!)

Essentially, whenever Firefox plays multiple sounds at the same time (for example, I use both youtube and discord in-browser) the second sound will briefly mute the other sound. (Going back to the discord-youtube example, if I am watching a youtube video and recieve a discord notification, the youtube video will pause for about half a second.) Or if a site has background audio but also plays a short audio clip when certain elements are clicked, for example, it will cause this "overlapping" issue. Again, this issue is only within Firefox.

I am using Windows 11 if that helps. I've already tried using a Firefox Refresh and peeking in about:config but I'm totally lost as to what I can try next, since I can't find any other examples of people with this issue online. Sometimes the issue briefly fixes itself but then reappears.

I have Ubuntu 22.04 (on a Dell Optiplex 3000) with a minimal installation. I downloaded Firefox 125, removed the SNAP Firefox and installed this Firefox with no issue. I can run "firefox --kiosk" and Firefox runs in kiosk mode with no issue.

I have made some changes in the "about:config" part of Firefox. I have also made some changes to the Ubuntu keyboard shortcut list. There is only one user created on this system and I have configured Ubuntu to login this user automatically upon reboot.

However, if I setup Firefox --kiosk to start automatically (I use the gnome-session-properties application to achieve this) and then reboot, Firefox does run, but it does not appear on the screen. If I enter the "switch windows" keyboard shortcut (ALT-TAB), the Firefox kiosk appears.

So, is this something I can fix by changing the Firefox configuration, or is it an Ubuntu configuration change. If so, can anyone tell me what I should do, or have an idea how to debug this?

Everytime i try to watch a video it says it can't play or it just sits there buffering. Youtube works but only lower quality, but every other site i go on doesn't. Twitch won't load, other sites show Error Code: 102630. This is only a problem on my browser on my windows pc I have. On mobile the browser works great and has no problem showing videos so it a problem for my pc browser.. I've tried all of the steps, i've updated, i checked drm and even went into config to check there. But nothing works, it still can't load videos. I have version 125.0.3 and for me it's the latest one. I even turned off all of my add-ons to check if it works or not but nothing there either. It worked before, just now the latest two months it hasn't. What can I do in order for the videos to load? Thank you for your time.

I have accidentally end up with two FireFox accounts. I want to combine them, but I can't change either account to the other one because FireFox tells me that the replacement email/account is already in use. How do I get around this?

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.
