Hi there, I was wondering if we could get a setting to change the aesthetics of the tabs in our browser. Currently, we have a 'button'-type highlight for our current tab, but I was hoping we could manage our themes or preferences to actually have the tab visually 'connect' to the browser page itself.

It would help a lot with visibility, and I would greatly appreciate either the suggestion as an option or giving theme creators the option to tinker with the shape of tabs as a whole.

I have three separate Yahoo email accounts. I set up Thunderbird to link to each Yahoo email account separately. It worked fine for a year or more. On 5/25/26 one of the three Thunderbird email accounts stopped downloading emails from Yahoo. I could see at the bottom bar Thunderbird indicating that is was downloading 1 of XX emails, but never actually downloads them. There is no error message. I checked the Yahoo email account to verify the number of emails I am missing from Thunderbird and the number is correct. I can see the emails in Yahoo. I'm the only person using Thunderbird, so no changes have been made to previous settings for retrieval. I confirmed Security and server settings for Thunderbird in and out going emails, and Yahoo are correct. I tested the connection in Thunderbird, and the connection is successful. I tried to send an email from the Thunderbird account having issues, and the email was sent and received by the recipient. The recipient replied, and Yahoo received the email, but failed to download it to Thunderbird...along with all the other emails since 5/25/26. I unlinked the account and reestablished the link between Yahoo and Thunderbird, and still not fixed. I tried restarting the computer, with no change. I tried to send an email from Thunderbird to one of the other Thunderbird emails and it was sent and received. I made changes to Thunderbird to force the download of emails, and it still wouldn't do it. I turned off my antivirus, closed Thunderbird, and restarted it, and that didn't change anything. The capacity of emails on the email in question only has 739 emails, so it's not over the limit and I have plenty of storage capacity. Thunderbird is set to save emails, Cookies and cache were cleared, no change. I ran the folder repair feature in Thunderbird, but there was no change. I compared all the settings between the other Thunderbird emails that are working against the one that isn't, and they are all the same. There was a suggestion to close out of Thunderbird and delete the "Global-message-db.sqite" file from the Thunderbird profile in case it was corrupted, and it would recreate this file when Thunderbird was restarted. The file was recreated, but it didn't fix the problem. There was mention that a suspicious email in Yahoo might be blocked by Thunderbird, so I placed various emails in the spam folder, and it didn't work. I did find one email in the Yahoo spam folder that was dated before 5/25/26 and moved it to the Yahoo inbox. Lo and behold, that one email downloaded to Thunderbird. So there is something within Thunderbird preventing emails from downloading after 5/25/26. I've read many people complain about similar download failures with no solid fix. Someone mentioned it fixed itself on a day, but then stopped again days later. Someone else mentioned Yahoo changed its password protocol to transfer emails, but that doesn't make sense since the other two are still downloading based on the "old" password protocol. I'm at wits' end. Thanks for reading all of this. I hope someone has a solution.

I have 5 Gmail accounts they r all configured the same I automatically let thunderbird install two but none of the other three will not connect i have tried everything i can think of but to no avail

dear support, plese help me, i accidentally remove message data when i want to move email to another laptop. usually if mesage data in local D, the checkbox will greyed but it grey and checked what should i do. i already use recovery software but inbox & sent file won't recover, only archive like 2025 & 2025.msf and it can't be oppened, message still empty although capacity of that file 3GB. any help will really appreciate.

Whenever there's an update, my saved passwords seem to disappear, and sometimes show up later on. Right now they seem to have disappeared again, so I made sure that sync is on, and everything is selected, but they still aren't there.

Please help.

Thunderbird will not let me move messages to the trash folder. If I do move a message to the trash bin the message will re-appear in the in-box. I have tried to follow the steps in the Mozilla support website but that did not work. When I try to delete a message I get the following:

The current operation on "inbox" did not succeed. The mail server for account rex@rexperry.com responded: [TRYCREATE] Mailbox doesn't exist: INBOX/ Trash (0.001+0.000 secs).

I am using an HP desktop machine running W11. This problem did not happen until I switched to the W11 machine.

Any suggestions? Thanks, Rex Perry rex@rexperry.com

Today TB froze during start up. No problems yesterday.

I deleted global-messages-db.sqlite and restarted TB. Now it is frozen with a "Loading messages". Maybe it is rebuilding indexes and this takes a long time and I should be patient.

Maybe my In and Sent mail boxes are too big? If so, how can I safely prune them?

TB is becoming increasingly unstable for me. It was very reliable before about a month ago.

I doubt my AV is the culprit because AV has not changed today.

Thank you one and all.

Hi - My mozilla email is tied to my old work email, i.e. a company I left in 2018. That company has long since folded. I never added a secondary email. I'm now trying to use features like the VPN etc but need to sign in to do so. Despite being signed in on mozilla(and remaining that way since 2018 across two laptop transitions) it still wants to send me a code to the old work email which is defunct and no longer active. It's kind of an even bigger problem because now I have to remember to navigate to this here forum since I won't get email notifications that someone replied! :)

What do I do? Is there anything I *CAN* do or am I S-O-L as they say? Again, the gold is just to switch out the primary email for my current, working, personal gmail lol

Many thanks.

Since yesterdayevening I am experiencing problems with connecting to imap.one.com with all four of my accounts in Thunderbird 157.0.1 (64-bits). It says something like "Connecting to the server at imap.one.com with username XX@XX.XX failed" (translated to English) Mailsystem at one.com (webmail) and in my Android (Bluemail-app) works fine. I tried to fill in the right passwords, even changed a password and tried the new one, but still no effect.

Settings: Servertype: POP-mailserver Servername: imap.one.com Port: 995 Username: emailadress

Connectionsecurity SSL/TLS Authenticationmetod: Normal password

I use the release-update-channel (if that is usefull info?)

What can be wrong?

Hi there I have been using Thunderbird for many years to manage the same many mail accounts on diverse PCs. I prefer using a portable version from portableapps.com, partly because when it comes to transferring to another gadget, it suffices just moving the portable folder, and I do not have to create dozens of accounts in a fresh install. Of late, I have been getting frequent irritating error messages for 2 Yahoo accounts. It connects to them & I can receive mail, but for automatic connections to the server in between, I keep getting error messages like: The current operation on 'inbox' did not succeed.' The mail account to abc@yahoo.com responded: p.', ... etc The other day, after reading about possible solutions from some forums, I decided to just delete both accounts and used the recommended Thunderbird connection settings for Yahoo to create the 2 accounts anew. I thought the problem was solved, only to have the same alerts every now & then reappearing, which amounts to a lot, if you have Thunderbird on many hours a day. I consistently update Thunderbird, the moment I'm alerted to a new version. I also have Gmail, Outlook, AOL(AIM) & other accounts, but not get similar issues. How do I permanently solve this problem? Thank you in advance.

I no longer have a right click menu available for photos in an email. There is only the option to zoom in or back out. My screen does not match what directions Google has to offer to fix the bug.

Hello, I am having an issue that Emails which are displayed in the reading area disapper for appr. 2 minutes. Afterwards they appear again. I have not been able to find out if this is a problem in Thunderbird, or if another application is causing this. I have read an article that Avast Antivirus is temporarily locking folders during scan. Maybe someone has had the same topic and can give me a hint where to search for the root cause. Thank you.

I HAD MY SCREEN SET UP SO THAT I COULD COPE WITH MY VISUAL DISABILITY AND NOW I CAN'T USE IT. YOU HAVE SCREWED IT ALL UP AND I HAVE SPENT HOURS USING AI TRYING TO PUT IT BACK. I HAD DECLINED THE UPDATE, BUT YOU DID IT ANYWAY WITH NO CONSIDERATION THAT SOME PEOPLE NEEDED IT THE WAY IT WAS!!!!!!! I WILL SUE YOU UNDER ADA IF YOU DON'T GIVE ME MY SCREEN BACK THE WAY I HAD IT. Details: I can't have left column bar; I need all my tools on the top bar like they used to be. You made the address bar so huge, I can't move things back on the top bar. You are using tiny symbols on the left bar that I can't even see to tell what they are; I need it in words, not tiny symbols. You took away the choices under the Google Search box so you can't choose to use AI or not. There's probably more, but that's all can think of at the moment. I'm so upset that my blood pressure is skyrocketing and I'll probably have a stroke. This is the second time since I've been a user that you have forced major changes on the users, whether they wanted them or not. I eventually got a usable screen after the prior changes, but it took me time I can't spare, and it was never perfect. Now what you're doing is even worse. Give us a way to go back to the old version so it doesn't destroy our lives like this is doing to mine. I will sue and move to a different browser if I have to.

hi team

How can I stop firefox automatically saving .pdf documents into my downloads folder.

I open and use hundreds of .pdf documents everyday, and my downloads folder is at capacity with my viewed pdf's.

please help.

Difficulty viewing my Firefox bookmarks page.

Summary: I want to launch a new tab, • open my bookmarks, • select one of my bookmarks and go there. Details: My device is a Samsung Android phone running the latest Firefox browser. I start by click the plus (+) on Firefox top menu bar. Firefox opens a new blank tab. The problem is the 3 dot vertical menu is gone. It's replaced by a camera icon. I use the 3 dot vertical menu button to drill down and access my bookmarks page. Is there a different way to open my bookmarks page that I should know about?
