When I access my email on my computer using Thunderbird, I have it set to downloaded the emails locally and remove from the server. Starting today, WHEN I access my email using Thunderbird in my phone, all the messages are still there, and I have to manually delete them, and they still stay on my computer email app. I need Thunderbird on Android to start removing them again once I clear the server.

Hello Since I changed my TB Android incoming server setting from POP to IMAP, Android has repeatedly reported app crashes. It asked me to clear cache, which I tried. See img attached. Eventually it said it was putting the app into deep sleep. Yesterday, after I sent an email to a gmail acct I was unable to find a copy of the email in a sent folder, there wasn't any Sent folder. There were only 2 folders, Inbox & Outbox. I expected there to be Sent & Draft folders. Eventually I discovered via Manage folders an Inbox.sent & Inbox.drafts. So I tried to change folders so Sent & Drafts are at the same level as Inbox & Outbox. Yesterday there were approx 26 emails in the Inbox. This morning there are 3 new emails in the Inbox & the 26 emails have disappeared & Inbox.sent, Inbox.drafts have disappeared. The 3rd & 4th attachments show the current folder settings. My TB Desktop incoming server swrting is POP. Please tell me what I am doing wrong & what I must do to be able to see all my emails, received & sent. Thank you

I use a local .html file as my home page in FieFox. There is no problem setting it to be used by the "homepage" icon on the toolbar, the little house. But now, unlike for years, I can not set it to be opened when I click the + to create a new tab. How can I work around this conflict with my long established patterns?

win11 :Thunderbird will not launch, It appears the issue is a Background Process labelled "Thunderbird" which is unresponsive to "end task" in Task Manager. Will launch after reboot.

I have no clue as to how Tbird into this state, but it has happened more than once

Thunderbird Version 156.0.1 Build ID 2026092215180

It is with a great deal of anxiety and concern I relay this issue. The mozilla webpage I have been using with great effect has crashed today without warning. Can a technical staff assist immediately. The long term damage is real and has an unfortunate side effect.

My email is [redacted] @cox.net, which now redirected to a Yahoo site. Was working unbtil a month ago. Now it says downloading emails on startup but I cannot get or see anything after 8/20/2026......

I disconnected a Google Workspace account - Calendar and mail - from a former workplace. As far as I can tell, it's been deleted from Thunderbird.

However, I'll still get dialog boxes and an occasional browser popup asking me to reauthorise it.

How do I get rid of it once and for all?

I start FF in safe-mode. I open a local page which includes only one URL. When I hover on this link I see (`tcpdump`) a DNS lookup being performed for this domain. I followed the suggestions from Mozilla but I still see this.

How do I stop this access.

I use FF "156.0 (64-bit)" on Fedora 44.

TIA

I recently installed Thunderbird on both of my Windows 10 PCs.

I have two email accounts:

axxxa1@shaw.ca

and

axxxa2@shaw.ca

The first account worked perfectly upon completing the Thunderbird set up.

The second account does not work and I have spent hours playing with various Configuration options.

It's very strange that BOTH of these email address successfully pass the "Connection Security" test.

I'm out of ideas.

Incidentally, I still have Eudora 7 on my PC and BOTH emails are working fine in that application.

Hopefully, you can assist me to resolve this problem.
