Good morning

Since this morning (05/03/2026) Thunderbird freezes within a minute or two of opening the program.

Everything in the program freezes up. I cannot even close it.

I am running Version 140.8.0esr on a Windows 10 PC.

Initially I was getting a pop up warning message that ask me to confirm if I wanted to send an email with attachments of over 20 MB. There were 3 or 4 such messages. I had not tried to send such emails.

I checked the Outbox in Local folders for old messages, but it was empty. I also checked the Unsent messages files in Local Folders in the Profile folder. I deleted the Unsent Messages.msf file to no effect. I renamed and replaced the Unsent messages file. Also no change.

I checked for crash logs but there are none.

I have run out of ideas as to what to try next. Does anyone have any advice?

I use an online retailer to buy birthday cards and gifts - Moonpig.com. Whenever I choose Paypal as my payment option, it logs me directly into my Paypal account without me entering any details. I have several Paypal accounts and want to choose which one to use. I have no saved payment details on Moonpig's site and having checked, they say that somehow my browser is logging me in automatically. That's Firefox and I want it to stop.

I have no issues with Firefox storing log-in details but I should be able to choose which Paypal account I want to use.

Any thoughts please? UF

Hi everyone,

I recently built a small Firefox extension for my website https://calcolo-stpendionetto.it https://calcolo-stpendionetto.it , which helps users calculate their net salary in Italy using updated IRPEF and INPS rates.

However, when I try to upload the extension to addons.mozilla.org addons.mozilla.org (AMO), I keep getting this error message: Signing is not possible due to an error with the manifest file

{

 "manifest_version": 2,
 "name": "Calcolo Stipendio Netto",
 "version": "1.0",
 "description": "Calculate your Italian net salary (IRPEF, INPS, regional tax) quickly.",
 "icons": {
   "48": "icons/icon48.png",
   "128": "icons/icon128.png"
 },
 "browser_action": {
   "default_popup": "popup.html"
 },
 "permissions": ["activeTab"]

} I also tried switching to manifest_version 3, but then Firefox gave a warning that some properties like browser_action are deprecated or not recognized.

Has anyone experienced the same issue when uploading finance or calculator-related extensions? Is there a new manifest format or signing rule I might be missing for Firefox extensions?

Any help or examples from working extensions would be greatly appreciated. Marien Klin

Please help.

after Firefox update all bookmarks stopped working and are not editable. All tabs crash, including Firefox help link from the Firefox menu.

Password list is blank - no entries

Is there any way to retrieve bookmarks?

I need to enter each url in the browser line and save bookmark for it to work.

Can you please help?

There are times when i am using Firefox that my PC will randomly disconnect from the internet. Sometimes it will reconnect on its own after I close Firefox. Other times I either have to restart my PC or go into Network & Internet settings and connect to my network. I am still running Window 10, free updates. Does anyone know what is causing this? It does not happen with any other browsers.

Es bestehen 3 E-Mailadressen (Konten), Nachrichten werden immer in allen 3 Konten angezeigt und gespeichert, wie kann die Zuordnung geändert werden so das Nachrichten nur in den angesprochenen Adressen angezeigt und gespeichert werden?

Hello everyone,

I’m wondering what exactly "remote improvements" actually are.

Mozilla says: "Remote improvements range from fixes to feature changes to Firefox. They are delivered remotely between versions and updates to make your browsing experience stabler and richer (...)."

They are not studies or A/B tests, as those are enabled/disabled separately. They also do not concern WebCompat shims, Safe Browsing, or similar features, nor larger security fixes or more significant bugs that are resolved with a out-of-band update – correct? Is it similar to Windows CU Previews - meaning improvements, fixes, and feature changes that would be included in the next upcoming regular update anyway? Not a case of "let’s roll something out and see how users react" thing?

Have I understood that correctly?

Thanks and best regards, Martin
