I keep getting spam where the option of marking it aw junk has been disabled, apparently by the sender. The JUNK button on the menu bar is grayed out, and the route of using the OPTION key and marking the item as junk doesn't work either.

Hi I bought a new android phone (the Xiaomi Poco F7) and I want to sync the Firefox from my Windows PC to the device. But when I try to scan the QR code it cannot be scanned. Please advise. Thank you

I keep getting this message "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox." every time I log in, try to delete an email that has already downloaded, and every time I click get messages to download messages.

No messages have been downloaded since two days ago. I did go on the web version of my email and deleted all emails from that time period in case there was a virus so it's not that. I strangely started when I ignored the compact folder message sever times. I did however try to compact the folder from the file menu, as well as cleared the cash and emptied the trash.

I made sure I had the latest update as well. I am thinking the software is corrupt at this point.

I've read everything apropos here, tried everything, and I'm lost--and totally screwed--if I can't get into my old Thunderbird. Spectrum, computer died, nobody competent here to get past "Registry Error," I guess, but I need all the data, contacts, calendar, etc., in the T'bird I've relied on for MANY years. PLEASE help. I tried to get a screen grab: It didn't work.

This is the second time I've appealed for help.

In an IMAP account I can create subfolders in all folders except the inbox. Subfolders created in the inbox become folders at the same level as the inbox. TB 140.2.0esr Screenshot of server settings, advanced attached.

Hello, After recently I installed ThunderBird after installing a clean installation of Windows 10.

I have managed to successfully connect ThunderBird to my Email Server, and its associated CalDav and CardDav server.

However when I try to sync the ThunderBird Address Book with the server, it only uploads information (new address book entries, edits, deletions). Changes made on the server do not get reflected in ThunderBird.

This includes the situation where the address booked entry is originally made in ThunderBird, uploaded to the Server, and then edited on the server (e.g. added extra character to the name field).

I can sync emails and calenders between ThunderBird and the Server without problem.

I have tried deleting the abook.sqlite files in my ThunderBird Profile, but this has not had any impact.

For avoidance of doubt, I am using the "Syncronise" menu option in ThunderBird rather waiting for the default automated 'every 30 minutes' setting.

Question: Can anyone advise how to resolve this one-way synconisation. I would like ThunderBird Address Book to update/reflect changes made on the server

LOGIN FAILED ERROR MESSAGE DRIVING ME CRAZY! At LEAST 100 times I get the same gray pop-up error message which I've attached. I will type it here as well

Login to server pop.earthlink.net with username professor[hidden for privacy]@earthlink.net failed.

Retry - Enter New Password - Cancel are the choices presented.

Obviously my primary email server is Earthlink Webmail, which in turn I redirect to use Thunderbird as my mail reading and filing system for my messages. Webmail is simply too cumbersome for daily use. No matter.

I have two email accounts with Webmail, both redirected to TB. I use a particular password for the Webmail server, which in turn I needed to set up a flow-thru account to TB. No problems there for the past 10 years or so.

Suddenly beginning last week, these infernal gray box error messages began appearing throughout the day. Now they popup every 2 or 3 minutes!

I have double and triple checked my Webmail passwords to insure they are correct. I have also attempted on NUMEROUS occasions to use the optional tab ENTER NEW PASSWORD, into which I have typed the password again. I check the box that asks "Use Password Manager to remember this password." in hopes that TB will somehow remember the correct PW. No Luck whatsoever.

To prove my point, during the time it has taken me to type this message, the popup has appeared no less than 6 times thus far, and I am not even finished with my question.

Actually - opps, there it is again - I am finished with the question. What I am desperately seeking is how to disable this damned error message once and for all, or to input whatever information it needs to simply disappear.

Thanks to you all for putting up with my frustration. I only hope it doesn't happen to you, 'cause it will drive you NUTS!

Thanks again,

Lenny

I have multiple gmail accounts set up on Thunderbird. They were all working fine until I traveled overseas and came back. Then, all of a sudden, 1 gmail account stopped working. The rest kept working fine. I checked the settings and they were correct. I removed the account and tried to set it up again (about 10 times), but kept getting the same error message: "Unable to log in at server. Probably wrong configuration, username or password." The automatic configuration passed and I even tried manually configuring to the recommended settings to no avail.

The only thing I can think of is that when traveling overseas and trying to get online, Thunderbird and/or Gmail asks for further security verification, and I just avoided using Thunderbird altogether while abroad. Upon my return, I started getting this error message. It is extremely inconvenient to have to use the Gmail interface for only 1 email (my main email!). Does anybody know anything I can do to repair this? I'm almost tempted to use another email client altogether to make my life more efficient as the new setup is not sustainable.

I used to troubleshoot when Thunderbird would fail to download new messages by looking at the last successfully downloaded email. But I can't find the error log. I'm pretty sure older versions allowed you to see the error log under Tools. But it isn't there and developer section is not helpful. I have tons of message filters going into folders so it is impossible to identify the last successful email download.

How am I to fix this issue if there is no longer a way to see failed email downloads via the error log?

I wasn't happy with the UI changes burying the menus into the hamburger on the side, but figured I could live with it. Not sure the benefit, maybe it looks cleaner? But removing functionality at the same time is really NOT helpful.

Anyone have any ideas how to find the error log or find the email causing Thunderbird to stop seeing downloadable emails?

I'm following up on https://support.mozilla.org/en-US/questions/1492943 which seems to have been archived without having been solved.

The issue is still present, I would like to use gemini in the sidebar chat with a different account than the "default" google account and/or an account sandboxed within a container.

It's a firefox issue because firefox doesn't allow for the sidebar chat to be containerised to use a different google account. BTW, It works for chatgpt but not for gemini.

Hi - I have a batch of a few hundred emails that include names and emails from a form that people filled out. I didn't know how to create a form that collected this information directly into an email list at the time (now I do, thankfully), so now I need to download specific data - name, email - from the body all of those emails into a csv file.

I used Google Takeout to download the specific emails and then imported them into Thunderbird. I used ImportExportTools NG to export the data into a csv file, but the data I need was not included. Is there a way to export data from the body of an email into a csv file?

Yesterday I tried to pay via PayPal for that the website opened a window and then PayPal ask for a 2fa and I switched to the authenticator and got the number, when I tried to switch back to the website it looks like it had started new and I was forced to enter my credentials again but the PayPal 2fa number had switched again.

Why is Firefox closed, when I switch to another app?

The same happens to me when I try to hear a podcast or a radio football game. I start the stream it runs and then the screen went black and then the streams stops all together. When I lock in, the stream web site shows like before I started the stream.

So what forces this behaviour? I couldn't find anything in the app settings.

My mobile has android 15.

I hope something be can point me in the right direction, how I can hear my streams undisturbed

Since about a week ago, possibly after the recent update, the tool bar icon of Firefox stoped working - now its a blank "document" icon. When hovering over the tool bar icon, the minimized version of the window displays the correct firefox icon over it, the desktop icon is also correct, but the blank tool bar icon persists. Reinstalling the program did not help.

It is a minor bug, but it's quite annoying when working with other text documents with similiar icons, or just with a lot of programs open at the same time.

Hi, Firefox updated my browser to version 142.0 on the 24 Aug 2025. After shutting down my PC and reopening the next day, all my opened tabs in the browser were removed and have dissapeared? I have checked the history folder, but only tabs from after the update are available. Where have they all gone and how do i recover them. Very frustrated !!!

Recently upgraded to windows 7, and upgraded firefox to version 115. Why am I getting notices that Windows Vista is no longer supported. [upgraded from vista to 7]
