When I go to another app, and back, tabs have to reload, often loosing what was done in the page. I have set Firefox as "No restrictions" on my Xiaomi 15 Ultra (HyperOS 3, Android 16), but Firefox still seems to unload memory very frequently.

I seem to be unable to install Firefox on my Windows 11 desktop because there is apparently an old version already on my computer. I wish to reinstall Firefox with your help

The last automatic browser update (147.0.3 (aarch64)) has wiped off all changes I made to bookmarks and passwords from the past year.

How can I go back to a previous version and recover my details?

This browser version is terrible and looks exactly like Microsoft Edge which is not intuitive at all. I don't want to set up multiple personas, Its just me and the one computer?

Please help me. Kerri

I have an existing account on my old computer. When I put Thunderbird on my new computer, it downloaded thousands of old emails but would not open new mail. I uninstalled and reinstalled and it still won't show new mail.

This is a new Fedora-42 desktop, upgraded (dnf upgrade) today. I installed Thunderbird today (dnf install thunderbird), after doing the operating system upgrade. I tried to add my yahoo e-mail account. Settings are as follows:

• create accounts in the new Account Hub is unchecked (off).
• accept cookies from sites is checked (on).
• remember password is checked (on).
• I'm using "IMAP".

When I click "Done", a separate window pops up in which yahoo asks for my password. After entering it, yahoo says "Something went wrong", and gives no other indication of what the problem is.

If I instead "Configure manually"... I tried both the default hostnames and "export.imap.mail.yahoo.com" for the outgoing server. I tried both "Normal Password" and "OAuth2" authentication methods.

In all the above cases, I get "Unable to log in at server. Probably wrong configuration , username or password." with a yellow background.

I see nothing of "Edge Too many requests" as was happening to several people recently.

How do I add my yahoo account to this new Thunderbird on Fedora-42?

Hello,

After today's Thunderbird update for Windows 11, over half of the folders in the local folder are no longer displayed. However, the folders are present in the backup folder on an external hard drive.

What's causing this?

Have been trying to set up some pop3 yahoo mail accounts on a new computer. I have used automatic configuration. I have used manual configuration using the data from my old computer. I have checked the configuration settings on both Yahoo and Thunderbird sites. In all instances Thunderbird verifies the account is valid, but the next window asks for my yahoo username and password. I cannot get passed this stage. I have tried entering my yahoo password and I have also tried the app generated password from Yahoo, all I get is a Yahoo "something went wrong" message. Interestingly I did manage to get one of the accounts to work yesterday, but I must have tried no end of different permutations and I have no idea which one eventually worked.

Trying to use Google Meet on my new Mac (OS 26.2) using Firefox (140.7.0esr (aarch64)) However, when I attempt to share my screen during a video call I get the following message instead: "Meet needs permission to screen share. You must grant permissions in order to screen share" but it does not provide instructions or links to where I need to grant these permissions. This is only happening when I try to use Google Meet or Zoom with Firefox. If I use Chrome (which I prefer not to) from the same Mac computer, I am able to do screen share with both Google Meet and Zoom. I have already tried the following: added Firefox to the Mac OS privacy & security accessibility and camera settings AND added both Zoom and Meet to the Firefox to the Firefox Privacy settings to "Allow" camera access. However none of this worked. What specific Firefox or Mac OS setting must I turn on so that I may do screen shares during video calls?

Starting Feb 8, 2026 my yahoo accounts no longer work in Thunderbird. I have accessed these for over a dozen years using Thunderbird. In addition, when I open Thunderbird at all I end up getting endless loops of yahoo login messages. The mechanisms in the messages do not work at all. I have received no Yahoo mail since that date. To troubleshoot the issue I tried logging into the accounts directly through Yahoo. Broken, with no access at all to any help resource from Yahoo. Although Yahoo seems to be keeping mum on the problems, there is spotty information online that Yahoo servers were breached a few days ago. One report claimed that user data for about a billion accounts was compromised. I suppose that may explain why my accounts no longer work anywhere- neither from Yahoo itself nor within Thunderbird. Is there a way to disable the incapacitating yahoo popups pending any larger solution to this?

I use both Gmail and Thunderbird. I can see both in Thunderbird on my PC. I would like to sync my TB address book with Google contacts. I searched a good while on-line and find information about adding a CardDAV Address book. However the instructions mention steps that simply are not available on Thunderbird on my PC. I have the latest version of TB (140.7.1esr (64-bit)). The first step says to "open the Address book, select File>New> CardDAV address book". That is not a choice. Anything in Mozilla support is several years old.

So is this possible or not?

I have Norton 360. I just reinstalled a brother printer and now I get the "Your browser is being managed by your organization". While I sync with my laptop, as others have said, I'm not an organization. There is an Enterprise policy .

Active Policy Name Policy Value ExtensionSettings {"firefoxhpsureclicksecurebrowsing@bromium.com":{"installation_mode":"blocked"},"firefoxhpwolfsecurityextension@bromium.com":{"install_url":"https://addons.bromium-online.com/wsx.xpi","installation_mode":"normal_installed"}}

I can't store or edit any bookmarks. How do I correct this? I need answers in very simple terms as I am very much a layman with computers. Thank You!

When using Firefox mobile for android, a black bar appears at the bottom of the screen, above the address bar. Please see attached picture.

It only seems to occur when the "scroll to hide toolbar" setting is disabled. The bar moves upwards when using the keyboard.

Please let me know if any more information is necessary.
