I have been using Thunderbird for many years. I have 4 accounts that have all been set up and working fine. This morning the 2 yahoo.com accounts stopped working. I logged in to the impacted accounts using a web browser and password just fine. I then updated Thunderbird to 116.0 to see if that would fix the problem, but it did not. The outlook and gmail accounts are working fine, for now.

When Thunderbird attempts to download mail for the yahoo accounts, I get a large pop-up window with "Edge: Too Many Requests". The pop-up window is blank except for that error message. I get the small pop-up with the Authentication Failure message. Sometimes I get Retry, Enter Password or Cancel. But I never see a window that will allow me to enter my password.

I can send/receive mail from the accounts while logged in via a browser but authentication fails within Thunderbird.

I made a custom theme for firefox and submitted it to AMO. It's approved, but I have no idea how to actually apply it. I don't see any option to install or use. What am I missing? How do I actually use it?

After the latest update, my default search engine in Firefox keeps automatically changing to Google, even though I’ve repeatedly reset it to Kagi. This seems like a bug, but let me know if there’s anything I can do on my end to make the change stick!

i downloaded firefox update 145 and it removed the minimize window, maximize window, and close window funtions at the top right of the screen. is there a way to restore them permanently?

I have just upgraded to version 145 and the title bar has disappeared Even though I have the Title Bar option checked in the customize firefox panel. If I uncheck the title bar option and then check the title bar option, the title bar will appear, but when I close firefox and then restart firefox the title bar is gone.

What the title says. At some point Firefox wanted to update to a newer version, it asked me if I wanted to refresh it, I said yes, nothing much happened besides I got a brand new folder I can't remove from my desktop. It asks for admin rights, I have admin rights, it's a local account, I am the only user, I tried the command prompt solution and it didn't help. Is there any solution to this at all that doesn't involve me getting into the bios?

I have my desktop extended across two displays. If I disable Hardware Acceleration in Firefox, entering fullscreen causes the window to be slightly offset down and right, leaving a thin band on the top and left sides of the screen where the desktop background and taskbar are visible behind the Firefox window.

From testing I have determined that this issue does not occur if I only have one monitor enabled or the monitors are mirroring the same display. I have also determined that the issue only occurs when Hardware Acceleration is disabled.

I have various shortcuts saved on the shortcut page comes up after logging in. Its set to 2 rows.. I use it every day. Used it this morning and working perfectly. Been out and when I came back the page is totally blank. I've tried sytem restore to 5th October but makes no difference. I use Windows 10 and read that Firefox are continuing to support Windows 10 I'm visually impaired and use a desktop PC with a large screen. I'm not PC techically knowledgeable. How do I restore my shortcuts or how do I re create them?

I updated firefox through apt, and since then, have not been able to log into twitch I am on ubuntu 24

apt list --installed | grep firefox firefox/mozilla,now 144.0.2~build1 amd64 [installed]

Attempting to log in returns the generic "Your browser is not currently supported"

On many of the sites that require hardware key for 2FA, what I should get is a prompt to press the Yubikey button, but instead I get a technical error. This has happened with logging into Google and Vanguard. Both use Yubikey as a 2FA.

I did not encountered this issue on Micrsoft Edge. I am running this on Windows 11 24H2. I believe it used to work.

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.
