No matter what I try to read or go to, Firefox crashes repeatedly. I literally cannot use it at all. I keep getting: Gah. Your tab just crashed. We can help! Choose Restore This Tab or Restore All Crashed Tabs to reload the page/pages.

Clicking those options fixes nothing! How do I go back to the previous version, please?

I have recently encountered reproducible failures when attempting to download files or save pages to local storage. The target directory is located on a mounted NTFS file system with the options umask=007, user=root, and group=disk. My Firefox browser is running under a non-root user account that is a member of the disk group. However, I consistently receive the error message: “XXX could not be saved because the source file could not be read.”

I would greatly appreciate anyone's assistance in resolving this issue.

I cannot often download emails via a hotspot. Sometimes one or two will come, then it will just stop. I get two different error messages. Most of the time I start with the "Home folder is being processed," then it will refuse to write to the disk. I have no issues at home or on wifi, only with a hotspot connection.

Since we frequently camp where there is no internet, this is a bit of a bother. This is xfinity email over a tmobile hotspot. Thanks for any hints.

Today my Windows 11 pro operating system updated itself to Version 25H2 (OS Build 26200.7171) When I opened Thunderbird it required me to put my account details in and then accessed my IMAP details. All my folders and sub folders were there but no Local Folders. How can I import them into Thunderbird please. Thanks

I am using Mozilla as my default web browswer in Unix environment. It is great... except for a particular behavior of the browser window. When I middle click (MB2) the frame of the window, it doesn't go to the background, like all my other windows. Intead it opens a new tab (when I click at the top of the window). This is very annoying becaue I use MB2 /go to background all th etime. Any idea how to change that behavior and make it consistent with my general unix preference? Here is how it looks: see attachment.

Thanks in advance.

When I approved the installation of the latest Foxfire update this morning, I got the message "Couldn't load XPCOM." Another popup message included "error status 0xc000012f." Firefox does not work. Thanks, Joan Karrie

Hello. For about a month or 2 videos on my mobile browser won't play with sound and sometimes they play without sound. The same situation I have with Brave browser. I tried Vanadium and IronFox and it works fine there. I really don't know what's wrong and how to fix it.

Can someone please help.. My passwords are saving. They auto fill...But before this latest version I had a few sites that I could ciIck on the bookmark and it would just open without having too log in.. I do have clear and delete cookies and history, but in previous versions these were in the exempt list so everything was saved. Would like that to still be in place both in private Firefox and normal.. This version has wiped out a lot of settings I assume I dont want to have to log in and go through check ups..Passwords and user details are there but not auto log in think there exception rule in previous version not sure where that is now

I can't find in mobile Thunderbird address book. It is not convenient to fill manually Adresse of Adressat to write email. There's no way to keep email address of people in email in non existent address book. Can you help?

The update to v145 completely changed how background color and highlighting of HTML emails are displayed. It was nicer before. Can someone please share which setting in about:config to change to return to HTML display in previous versions?

Thanks!

One of the things I like most about Firefox is the home page with 'tiles' for my most used websites. Since the last upgrade some of my tiles have the website logos but most do not. Is there a way I can fix this?

I've been a Thunderbird(TB) user for many years. Or I should say "was". A few months ago my computer was hacked. As a result I was unable to access my TB account. Since then I've had no choice but to use Gmail.

  When I lost access to TB I also lost all of my contacts. Is it possible to get a list of those contacts. Even if it was just the names, and not the passwords, that would still be big help. My  username here was pwrichcreek@twc.com. That email address is no longer valid.

Thanks for your consideration, SweetTasha

Recently, if I am playing audio from Firefox on my phone, the audio stops when my phone screen is locked. This did not used to happen and does not happen if I play the same audio from Safari. I am using an iPhone 17 Pro running iOS 26.1. I have tried resetting the phone and removing and reinstalling Firefox, but it persists. The problem does not occur with audio played from the same webpage through Firefox using my iPad, logged into the same Firefox account.

When I forward an email, all of the metadata is displayed at the start of the message. How do I stop this? I'm concerned the recipient will not bother to scroll down to the actual message contents. Thank you!

Hi,

I hit an error configuring two gmail pop accounts: "incoming server already exists". I do have an existing account on Thunderbird, also gmail, but not sure why this is an issue. Any help would be greatly appreciated!

Somehow I have many emails on the same topic (like 40 or 50 of them, going back over several months, even years) all piled up on top of each other, and then I have to close them all one at a time when I need to switch off my PC.

It does not seem to be due to being in Conversation View. I have followed 2 or 3 videos re how to get out of Conversation View, going into settings etc, only to discover I appear to be not in it in the first place.

Is threading different from conversation view?

Bookmarks & shortcuts that I visited and tried to keep them.. Firefox (at Samsung Galaxy X110 Tablet ) shows the first letter of these visited sites,or Google' s "G" letter.... but Firefox (at Ubuntu Notebook) shows the icons of these sites. I would like to see the same vision (icons) at my Galaxy Tablet also... Thank you for your support Ali Eren
