Something horrible and time-consuming has changed within this past week to Thunderbird. My version is 140.7 1esr 64bit. Over the past 4 days or so, I've found I cannot scroll down and see the full emails--until I have to use this new pop-up system.

This is definitely not an improvement in my estimation. Is there any way to undo this?

For many years I have had a Thunderbird Calendar, and have a large number of Tasks set up in it. I have now decided it would be convenient to link it to my Google calendar, so that it also shows on my new Windows 11 machine and on my laptop. I've gone through the process described in the "Create new calendars" article, to link the calendars, and the Google calendar is now appearing in the Thunderbird calendar, but not vice versa. How do I get the Tasks in the Thunderbird calendar to appear in the Google calendar?

I am running Thunderbird 140.7.1esr and Firefox 147.03 on my Windows 10 machine, which I used to set up the link. My Windows 11 machine has the same Firefox build, but Thunderbird 147.0.1, and the Google calendar display is the same, but I haven't yet set up the Thunderbird calendar on the new machine.

Thunderbird Version 140.7.1esr, Build ID 20260123195141 User Agent Mozilla/5.0 (X11; Linux x86_64; rv:140.0) Gecko/20100101 OS Linux 6.1.0-33-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.133-1 (2025-04-10) OS Theme Xfce / Adwaita Application Binary /usr/lib/thunderbird/thunderbird-bin

Having a problem with an ATT POP account. TB stopped getting mail. After a minute and a half or so (wish it would time-out faster), I get a pop-up box in the top right of the screen that states: "Connection to server inbound.att.net timed out" and then quickly goes away.

Deleted passwords and cannot see where to create them again, as it never prompts me for new ones.

Thanks.

With my Pixel 9a Android 16, I installed TB Android mobile by the export/QR code method. The settings were imported into the phone from my desktop, Win 11 TB version 147.0.1 and yahoo.com for my email service. I went through setup successfully, however, when I tried to sign in I receive an error: Oauth sign in failed. Oauth is currently not supported with this provider. Retry does not solve the problem. On my phone the settings are: Server is: pop.mail.yahoo.com Security SSL/TLS Port 995 Oauth 2.0 my user name @yahoo.ca These are the server settings on my desktop as well. Next step in the setup is to "Sign In". I immediately get the "Oauth not supported with this provider" error. I tried IMAP, same error. Under Oauth 2.0 there a pull down menu with: Normal password, Encrypted password or Client certificate. I'm not sure what these options are or if I can use them, ie with my Yahoo mail id and pwd. I tried IMAP server and got the same error. I'm hoping that someone can advise me as to how I get past this Oauth 2.0 error and finish installing Thunderbird for Android. Thank you

So either firefox or android (probably firefox) just updated, and it's made a mess of the browser. First of all, the layout of everything has changed - the traffic light menu's at the bottom of th e screen now, completely different, there's a pull bar to see stuff that was previously readily available, the tab icons are longer for some reason but I think they're also skinnier? The hell? It's just generally worse than what it was before. I hate every part of it and want it rolled back on that basis alone, because I actually liked how it worked before, and if I want to change how my phone works I'll do it myself. Stop messing with my stuff, mozilla, I don't come into your house and start moving all your furniture around and putting your cutlery in the wrong drawers, and I'd appreciate it if you returned the courtesy.

But, as annoying - read, infuriating and unnecessary - as that is, that's not the real problem. Oh no. No, that's a personal issue, I'd either learn to live with it or I'd find a modification workaround to get my old UI back. No, the problem is that my previously smooth tab screen - you know, the one where you can see all your tabs open - now lags. Noticeably. How do you mess that up? Seriously, what did you do? It freezes when I'm scrolling up and down! How! How do you do that!

In summary, update bad for UI reasons (please stop moving things for no reason, or at least give us an option to move it back, some of us hate that Really Quite A Lot, to the point where we left chrome over it) but also for previously-nonexistent latency where there absolutely should not be any. I'm on a Fairphone 5, this isn't an ancient brick that barely runs. How do you update something to be actively less functional? Please just roll it back. And if you only take one bit of feedback from me ever, stop touching the UI. It's really annoying. Please. Just don't.

In a recent Firefox update, UI was updated to reflect Material Design. However, some elements aren't displaying as intended. However, the screen with tabs is not displayed on the entire screen (that is, it does not extend into safe zones), although the indents on the screen allow this to be done.

I recently had my firefox mobile for android updated apparently, but it is so user unfriendly and not very accessible in the way that the new layout with the dark tabs and small pictures makes it very hard to read which tabs are open and is unfriendly on the eyes. Is there any way I can revert back to the previous version? I really loved the layout and the user friendliness of it and now I am just considering downloading another browser because I am so bummed by this update. Thanks in advance.

Tab management has been changed. Very annoying new UI design.

I can no longer share all tabs with one click.

Please bring back this feature.

Is there a setting to go back to the old behavior?

In which version had this feature?

Where can I download  old version's APKs?

bold textI recently had my computer get stuck in the "automatic repair" loop making it impossible to boot up. I restored a several months old back up onto a different hard drive. I can boot on the new hard drive, but Thunderbird is missing several months of e-mails. I have tried importing from the old hard disk, but IT DOES NOT WORK. Alll it does is create a new "Local Folders" with nothing in it. I have tried exporting the old profile to a zip file, but it is 14 GB, more than Thunderbird can handle. How can I import the old e-mails into the working version of Thunderbird on the new hard drive. Please, do not say "use the import function" as i have already found it does not work.

Context: So, I needed to get into Pear Assessment for school (I use my personal computer for school too) And I couldn't get into my Practice Test, so my mom suggested that I delete my history in an attempt to get in. So then I deleted it also thinking it might have a chance at working. But it didn't, and now I deleted my personal history for nothing. Please help me. Thank you.

(It is my first time using this website. I am a child, so I'm not sure how to answer everything in means of details. Also I put this on "browse" because, you know, browsing history. But I do know that my MacBook is a: ["macOS High Sierra Version-10.13.6 MacBook Air-(13-inch, 2017) Processor-1.8 GHz Intel Core i5 Memory-8 GB 1600 MHz DDR3" Hope this info helps you])

Bye, and have a good rest of your day. And don't let anyone tell you otherwise!

After creating an email message, I click on attachment button to attach a file or pdf document to the message. The file explorer screen opens for a second then closes, giving me no opportunity to attach anything.

I am running Windows 10 22H2, Thunderbird 140.7.1esr.

I cannot display some emails that are found when I make a search for a specific word and partially displayed. Therefore I understand they are still there.

However, when I request a list of these emails, none is found. Same thing if I try to fully edit them. I understand the index is somewhat damaged. How do I fix that ?
