duplicate of /questions/1553385 thread in Thunderbird for Android section

Thunderbird app on Android suddenly stopped moving emails; instead just repopulated inbox. Uninstalled and reinstalled app; added email account and proper password. TB locked into "Checking incoming server settings" loop. Comcast properly set up; accessible from browser. Tried entering settings manually; same result. Cleared cache and data; same result.

Hi I wrote before that Thunderbird won't let my emails through. I realise that I didn't leave my email address it's [edited from public] @dodo.com.au. Thanks Richard Starrett

Before the problem started, there was normally an instructions box visible on the screen when in Thunderbird. This box included instructions such as open, close, delete etc files. Now that box (at least I recall it as a box) does not appear. Now, eg, to delete a file I must right click on the file and hit the "waste" bin.

I would have added a screenshot of one of my in boxes but I cannot get the screenshot key (Prt Sc) to work. What it would show, if I was able to print it, is an inbox screen without any instructions box.

think I must have deleted an email received today from PayPal in error, as I can't trace it in my inbox - can you advise on how to recover it, please. I am not too hot on all things computer-related

duplicate of /questions/1544917 thread

Everthing was fine but last night it stopped sending emails saying verification failed for my email address. I installed this on my phone yesterday and imported info from desktop version

duplicate of /questions/1549163 thread as it has a reply.

Today as I got to work (Windows 11 machine), I had a suspicious Firefox.exe file on my Desktop, it was not a shortcut, but exe file. I did a little investigation and research, and I noticed some difference from Program Files exe file and Firefox.exe on my Desktop:

C:\Program Files\Mozilla Firefox\firefox.exe

Size: 695424 bytes SHA-256 hash: EEB242895F8ED48B43EAAA9ECA06C6DDE54425F8AE0E16200D2D46F839B9A540 File version: 145.0.0.327 Copyright: ©Firefox and Mozilla Developers Date modified: 16.11.2025 12:35 Original filename: firefox.exe Digital Signature: Mozilla Corporation

and Firefox.exe that appeared on Desktop

C:\Users\User\Desktop\Firefox.exe

Size: 389248 bytes SHA-256 hash: E8DA5735FE1B5E92BA3636B8D17B5BEC0EA521DB6A8B5A52177FF3E8B2F60710 File version: 145.0.0.327 Copyright: Licence: MPL 2 Date modified: 16.11.2025 12:35 Original filename: desktop-launcher.exe Digital Signature: Mozilla Corporation

I scanned both files in VirusTotal, and they both seems clean and legit

I uploaded both files to:

https://drive.google.com/file/d/1kALgQbfhIpHqs1pN6dmTdF71nm10LlD-/view?usp=sharing

Can somebody assure me that both files are OK, and can somebody explain to me why Firefox.exe appeared on my Desktop, and why is there difference between two files in size, Copyright info, and original filename ?

Coloured attached PDFs are displayed and sent in black and white, in both normal and troubleshooting modes.

This is not the case with DOCXs and JPEGs.

In this version, do I still have another account and password from other application that already saved before in the past version?

JPEGs and DOCXs keep their colour.

Dear Firefox Support Team,

I am reaching out regarding an ongoing issue with the NordPass extension on Firefox. For over a month, I have been encountering a source map error when attempting to log in using the Windows Hello PIN code.

The specific error message is as follows: Source map error: Error: NetworkError when attempting to fetch resource. Resource URL: moz-extension://23234j35k5j439434932u2j32l/css/biometrics.css Source Map URL: biometrics.css.map

I have already contacted NordPass support, but unfortunately, I have not received a resolution. I am hoping that your team can investigate and address this issue.

Please let me know if you need any additional details.

Best regards, Alexander

Most local folders are missing from Folder Pane view

Have a bunch of local folders that i use for archiving stuff which normally sit under Local Folders in the folder pane, but they have disappeared from view :-( If I search for an email that i know is in one of the local folders then it does appear to find the email, but when i click on it, it does not show any detail for the message. The local mail archives still seem to exist on my hard drive - see image 1 & 2. The TB folder view is image 3. Contents of profile/Mail folder shown in image 4 (some of missing Local folder are in the tree but not all!)

Yesterday, I enabled the Microsoft OneDrive protect documents feature, not sure if this is related to issue as cant be sure when Local folders disappeared (sometime in the last week though!).

Help much appreciated!

I want to know if it is possible to use multiple instances of Thunderbird (different versions!) on the same computer. The add-in "Attachment extractor" does not work beyond version 52.9.1 and it is so handy that it justifies the use of an older version of Thunderbird. However, I only need it once per month (each month!), because of invoices (yes, I work in accounting). Any suggestions would be appreciated. An update of the add-in would be more appreciated, even when payment is needed. PLEAAASE!
