Hi. Please could you guide me through moving my email messages from a POP3 account on one Mac to another? I have an old iMac (late 2015, Monterey) that I am tearing down for parts, but this has been my main Thunderbird computer. It is running the latest version of Thunderbird (153.0.2), as I updated it to do the Export. I am trying to move my email accounts onto my M1 Macbook Pro. When I first installed Thunderbird on the Macbook I was delighted to see that my data and settings for the IMAP accounts had somehow miraculously (to me!) migrated. But I have a POP3 account which has only partially moved across. It seems to be receiving new emails, but all the Inbox history is missing, and other folders such as Drafts and Sent are not there either, I just have Inbox, Spam and Deleted. I have tried your Export/Import method twice, but to no avail. In the expanded profile on my USB stick I can see Mail>mail.oddplanetstudios.co.uk which looks like it might contain all the files and messages. Now I want to move them across into Thunderbird, but I don't know what the steps are to do this. I would be very grateful if you could lead me through this, if it is indeed what I need to do, or give me some directions to do it differently. Many thanks.

The app itself sorts ubread mail at the top, this is obviously vert useful. What seem strange is that the home screen widget does not do this. That setting would be doubbly useful on the widget where a quick peek to see what is what is the entire point.

Is there a way to configure the widget to also do this type of sorting?

Running on Windows 11. There are many supposed "solutions" on the Web, but none of them work. I have tried with: about:config, css files, etc. None of them work.

I like Firefox greatly, but this is so frustrating.

The developers have created a solution to a problem that didn't exist. The result is to make Firefox user clumsy.

It would have been nice if they - at the very least - had provided a way to change the 'Profiles' icon position on the menu.

Again, Firefox 153.0.1 (64-bit) on up-to-date Windows 11. Amd Ryzen 5, 6 core processor, 32 GB Ram, 500 GB SSD C drive = 197 GB free.

title sums it up mostly. I've entered troubleshooting mode; no discernible difference. When I switch profiles the issue is resolved even with the same YouTube account. Tried clearing the cache, nothing. Most recent version of Firefox, windows 11.

The SEND button has vanished in Thunderbird. I don't recall changing anything or performing any updates, though my memory is getting to be unreliable.. In addition, the LINK button has vanished as well. I imagine I did or am doing something stupid and it's an easy fix, but what that might be totally escapes me..

Hi - I am running Thunderbird release 140.12.1esr (aarch64) on a desktop Mac runnning Sequoia 15.7.3.

Thunderbird is set up to take addresses from my personal address book. When I bring up Collected Addresses in the Thunderbird address book, there are no email [or any other kind of] addresses listed. Absolutely nothing in Collected Addresses within the Thunderbird address book.

There are 21 email and other addresses listed in my Mac OSX address book. When I search my stored email messages, Thunderbird brings up each and every address that matches the string in my query. The matches appear to go back more than twenty years.

I have searched the web on how to clear the autocomplete cache. There appear to be several different methods. I have tried bringing up the matches via the string and the resulting query, and then scrolling through the matches with the down arrow key. When I reach an address I would like to remove from the autocomplete cache, I have tried clicking on various combinations of keys. These combinations include:

1) Shift + Delete keys 2) Option + Delete keys 3) Command + Delete keys 4) Option + Command + Delete keys 5) Just the Delete key

My intuition tells me the autocomplete cache must be stored somewhere in a file. I cannot conceive of the autocomplete cache being maintained across versions, hosts, etc. over a period spanning twenty years without getting stored in a file.

Please enlighten me on how to clear out the junk email addresses in my autocomplete cache.

Thanks in advance for your help.

Corwin

Won’t let me sign in says I’m using os 18.7 I’m not and at one point was shared with n unknown device and now Knox is installed not me doing and fire fix was installed not me so yesterday I officially put it on MY PHONE n now icant use it cause someone else is using it too with my phone credentials.

It seems to be related to video playback but not sure. It was happening while a video was playing full screen, and also after stopping playing/hiding a non-full-screen video.

To catch the issue had to screen record at 240fps. I used Nvidia Overlay to record the issue, but was happening before the overlay was even enabled.

Disabled all addons, made no difference. HW acceleration on or off, still happened.

I tried turning on logs, and this always seemed to show up with the flash: ``` 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 ```

Why the h377 did firefox change the screen shot tool by removing it from the address bar AND delete the center search bar, along with changing the location of all my recent web visit from the along the bottom of the screen? This is annoying and unhelpful to pc users, I need these functions back like they were in order to us your site on my pc. I donot and will never use firefox on my phone. If these functions are gone, then I will have leave as well. Either that or remove the update from my pc and cease ALL further updates.

I changed my password for Greenby/Plusnet today. Now Thunderbird is unable to connect to them. The password is correct as I can enter website directly. No problems before change. Grateful for help.

Should I reinstall?

Recently (past few weeks) I’ve found Firefox on my iPhone (iOS 26.5.2) has stopped loading. I’ll open the app and it won’t load the page at all. It also doesn’t let me reload the page, add tabs, or close tabs. Occasionally it will fix if I click a link from an SMS or something that then opens in the app. Quitting Firefox doesn’t work, restarting my phone also doesn’t work.

my translation is from English to French . Request for this to change to French to English please . fed up with continually having to change this around manually. It should nbe a simple as pressing a button ?

Thunderbird just updated and the next time I opened it all of the folders I created and the emails I'm storing within them are missing. I found my profile as directed. I'm not sure if I have a backup of it. I've included the screenshot as you ask for. I know that those folders and emails are there as I was playing around with the the 3 lines > View and when I moved between the different choices I saw my folders/emails are all in there.

Any assistance you can provide is appreciated!
