Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

I've been using T-bird for a couple of years without a problem. A couple of months ago, T-bird started sending me error messages and no longer sent outgoing mail. I checked with Spectrum (my main mail provider for email: mad1doc@twcny.rr.com) and it looks like all my settings are correct. I have 2 other Gmail accounts and they both work perfectly. I'm including a screenshot of the most recent error message / server refusal. What do I have to do to fix my RR email account?

I don’t know how it happened but I can no longer type into the url/search box in Chinese when using the ios app. I’m having to type out everything in a notepad app and copy paste into Firefox which is becoming tedious. Switching to the English keyboard works, it just Chinese keyboard that’s blocked. I can’t find how to fix this in settings. Please help!

Hi guys. I have a problem with the program, I'm not receiving anything from anyone, and also when I send messages, I got this message : "Your message was sent but a copy was not placed in your sent folder (Sent Mail) due to network or file access errors." My account is on google, and I've been using tunderbird since 2017y. Any solution for this?

Hallo, in der Desktop Version funktioniert das verschieben von Mails in Ordner eines anderen Mailkonto ganz wunderbar. Wenn man auf Verschieben geht werden alle Ordner aller installierten Mailkonten angezeigt und ich kann die Mail in den notwendigen Ordner verschieben.

In Thunderbird für Android kann ich nur innerhalb des einen Mailkonto verschieben, was die Arbeit doch schon einschränkt.

Ihr hattet verkündet, das Thunderbird für Android die gleichen Funktionen erhalten soll wie die Desktop Version.

Gibt es eine Aussicht auf diese Funktion bei Android?

Hello everybody, I'm facing an issue with an icon appearing on some sites and propagating down to the print out of the pages. Let me give an example: I'm interested in an article published on: https://www.electronicdesign.com/technologies/analog/article/55246421/modeling-on-mondays-nonlinear-spice-models-of-vacuum-tube-triodes-part-3?o_eid=9960G5790701E5D&oly_enc_id=9960G5790701E5D&rdx.ident[pull]=omeda|9960G5790701E5D&utm_campaign=CPS241216087&utm_medium=email&utm_source=ED+Power+%26+Analog When I open this page, an icon appears in the low left corner. And when I try to print the page, the icon appears on each page. If I use the simplified print mode, a kind of background of the icon (white box) is still visible on each page and can hide the text behind. On top of that the images no longer appear in the print out...

Any help to sanitize that is welcome.

For a few days, for unknown reasons I have been unable to access my blog..."Kitchen Connection". This has never occurred before, and it is very annoying. I have been blogging for many years.

Your assistance in this matter would be appreciated. Thank you in anticipation.

I've tried submitting the above a few times...and for whatever reason, it has not gone through to you, it would appear.

I am using Thunderbird 128.5.2esr, Win 11. My screen resolution is 1600 x 900, when using for example Message filters I cannot see all all of the image to allow me to accept what I have done. The buttons are off screen and cannot be accessed. If I change to 1920 x 1080 everything is accessible.

Any suggestions other than change my screen resolution.

For the last month or so every time I restart Firefox (macOS 15.1.1) it asks for the master password, which I have saved in a third party password manager. Every time the prompt pops up I use my password and it won't accept it so I have to reset my password. This week I deleted the app from my computer, rebooted, redownloaded Firefox, and reinstalled it without any change in the behavior. Anyone have any ideas?

It's sort of difficult for me to explain. Other than I have used both Mozilla and Google. I have a Gmail account and a Proton mail account and I changed my email for Gmail by eliminating the last four digits of my social security number. Which used to be my Gmail address and I believe that I was using my last four digits for my proton mail account also? But to be honest I am not really sure of that? So to attempt to simplify my situation. [edited] @gmail.com is my email address for Gmail and I really don't know if I changed this for proton mail account also. I am definitely getting old. Because I will be 68 on the 23 of this month. And I remember the days when none of this even existed. So I am sure that there must be someone who can help me straighten this mess that I created out and please help me simplify my life again. Thanks to whoever reads this and replies. They have to understand that cell phones didn't exist for me and many others when I was young. Computers didn't exist as we know them then either. But obviously I have learned alot in my 68 years of existence.

I can see and manipulate my extensions in the little puzzle piece in my toolbar but when I go into settings all my extensions are gone, replaced by an extension I did not authorize. I was having difficulty with a pop-up on a news site that wanted me to turn off my add blocker or buy a subscription. When I go into the add browser and turn it off the website does not recognize that I have do this and keeps me from getting behind their pay wall. So I thought I would go into the settings and temporarily turn off the extension from there and that is when I discovered the lack of extensions in my settings.

The add on is AdBlocker Ultimate and the website is RawStory.com

when we set the default zoom some percentage e.g. 80% in settings> the zoom level of the toolbar/ addons/ extensions is not set to 80% also there is no option to set the zoom for particular sections such as zoom for the system toolbar, pages, side menu, address bar. The main issue is when the default is decreased> the zoom in the addons/ extensions remains still at 100% which pop-ups on the screen and the addons/ extensions settings cannot be accessed due to zoom in on the panel (it happens when scaling of the windows in set to high percentage such as 130%) so the Firefox zooms in at 130% by default (considering it as 100% in firefox)> and decreasing zoom to 80% (to get 100% zoom from 130% in firefox) so it doesn't work> u understand> what is the solution tell quickly. I have tried to set the compatibility Troubleshoot and override the system Scaling in Program settings. It also doesn't work. Tell me the solution soon.

I am not going to embellish on the confusion that I am experiencing right now. Because I really don't know how to explain it completely. But I use Firefox and Google. And I have a Gmail and a proton mail accounts and have changed my passwords so many times I couldn't possibly remember. But I am only trying to simplify the complications I have caused over the years in my own digital world.
