Hi,

How do I change the color of the white border and the color of the arrows?

I have menupopup > menu, menupopup > menuitem { -moz-appearance:none!important; color: white !important; background-color: #1551C0!important; } menupopup { -moz-appearance:none!important; background-color: #1551C0!important; border:none !important; padding:5px 0px 5px 5px!important; }

I have .menu-right { filter: invert(100%) !important; but it only turns the arrows white in some locations but not in the bookmarks menu and not in the right-click menu.

I want to prepare emails in advance (in the Outbox folder?) and have Thunderbird send them later, at a time that I specify when I prepare them. I looked at the Events and Tasks tab but I can't see how to do what I want with a task. All the prepared emails can be sent at the same time. Can it be done? Thanks Peter M

hi all guys ... I'm experiencing several issues with oauth2 authentication, and I never had any issue before February the 2024 ... at the beginning the only account I have was not working was a microsoft account, so I thought it was "because of microsoft restriction"

but now, little by little, all my accounts requiring oauth2 authentication are failing, and I don't know were to check ...

I do NOT have any httpd/apache server running on localhost

I already tried changing things like general.useragent.compatMode.firefox or network.protocol-handler.warn-external.http network.protocol-handler.warn-external.https

I also created another blank profile ... but again ... not way to make it works ...

cookies are permitted ... javascript is enabled ...

the result is always the same ... a blank page when I try to do any oauth2 authentication ...

if I manually copy/paste that link in Firefox/Chrome it perfectly works, so it's not a network connection issue ...

from what I can understand, it seems to be related to the "built-in browser" in thunderbird, that for some reason does not work "as expected" ... If I try to click on any link for example in the settings page

like the "learn more" link of this option Send web sites a “Do Not Track” signal that you don’t want to be tracked "learn more" thunderbird does NOT show anything ...

something is broken, and I can NOT understand what it is ...

is there anyone with some good advices?

please let me know

thanks in advance

There is no option for message headers under View. How can I see email message headers in Thunderbird?

I Googled how to do this but they all say there is an option in the main menu under View. Maybe at some point there was, but not now. So how can I see the email headers?

I have 4 accounts with different names but all with the same domain name (name1@samedomain.com, name2@samedomain.com ...). The first one set up perfectly and works. The 2nd and the 3rd can't retrieve mail from the server (didn't try the 4th yet). The SSL ports are the same for all. The passwords happen to be the same for all. (I haven't tried changing the 2nd and 3rd passwords as that seems unlikely to be the problem.) When initially setting up the 2nd or the 3rd I get a "Sending of password for user name2@samedomain.com did not succeed. Mail server pop.yyy.zzz responded: [AUTH Authentification failed." I've checked the passwords on both the client and the server ends multiple times and they are the same. Then, of course, periodically I get a pop-up with "Login to server pop.xxx.yyy with username name2@samedomain.com failed. When I go to the Account Settings screen with the 3 accounts and click on each Server Settings one after another, the only thing that changes is the User Name, yet the first account receives mail and the other 2 don't so everything is correctly set up. As an aside, I CAN SEND emails from the 2nd and 3rd accounts but can only RECEIVE and SEND from the 1st. Any help appreciated.

when I try to send an email you ask for a pass word for jojack@dslextreme which I havent had for years

I am running Thunderbird 115.9.0 on Lubuntu 23.10. I have 4 IMAP accounts I use. The folder and file is not shared and I am the only account with access to the directory.

I use emoji as tags for messages, and have a large number of filter rules defined, nearly all of them Tag a message and set the Junk Status to `Not Junk`. These rules are all set to execute `Manually` or on `Getting New Mail`.

If I select a given inbox folder for a mailbox and select `Tools` > `Run Filters on Folder`, all of the messages are properly tagged, however, after some time (10m?, On new mail receipt?) at least one of my mailboxes will lose all of the tags that were previously set for messages. Manually running the filters will restore the tags, until they disappear again some time later.

I've not seen anything in the Browser Console log (but perhaps I'm not using the right term?) Is there any way I can diagnose or fix this issue? Thanks!

In my attempt to help my wife with her email problems I have managed to totally screw up her profile. There now duplicate inboxes, duplicate local folders, duplicate Outlook Express Import files, etc.

Is it feasible to export/backup the inbox, address book, files&folders, Outlook Express Import files (but not the profile), then uninstall Thunderbird in order to start over? If so, how is the best way to do this?

She only has one email account on Thunderbird and is running Windows 10.

Thanks in advance for any help.

Hi everyone. I have installed Firefox on all windows 10 workstations and I have also installed latest Firefox Group Policy ADMX on Server. I need to set some preferences on all Workstations. The preferences that I want to set are the ones that can be found in about:config.

But the problem is that only some of these preferences exist in Group Policy by default and it says "deprecated". I know that I can add additional about:config preferences in a Group Policy object called "Preferences". But no matter how I enter the format or how I change the JASON file, no preference policy is applied to Firefox in workstations. By the way when I change "Preferences" gpo in group Policy the next Policy called "Preferences (JASON on one file)" does also change. I have thoroughly searched the web and Mozilla support and have tested all suggestions but all to no avail. Can you please help me and Give me an example of how to do that? I would appreciate any answer in advance.

When I download PDFs on my MacBook using Firefox (currently 124.0.2 (64-bit)), they are always blank - I have attached a screen shot.

But if I download the same PDF using Safari, it opens straightaway - 2nd screen shot.

Is there something I need to adjust in Firefox to allow PDFs to open?

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

Hello. In our company, every employee has an IMAP account, but over time the IMAP profile takes up too much space on the hard drive (100-200GB per user...). What can we do to have more storage space? Can we delete the file? Or will all emails also be deleted from the server?

I've been trying out Thunderbird and Spark for the past few weeks, and decided to go with Thunderbird to replace Windows Mail. After uninstalling Spark, I changed all my email passwords, and now Thunderbird can't connect. I deleted my Google and Xfinity email accounts from Thunderbird, then closed and reopened the program, but I'm still getting this error from Google when I fill in the credential info it automatically asks for when re-adding it to my account:

"400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

On the "set up your existing email address" page in Thunderbird, I'm getting this error (see image), even though the copy/pasted password works fine when logging directly into Google.

I also can't reconnect to Xfinity at all. The 3rd party box is checked in their system, but when Thunderbird tries to connect, it looks like it's auto-filling and submitting a password on my behalf, without stopping on that screen so I can change it.

I did this: https://support.mozilla.org/en-US/kb/password-manager-remember-delete-change-tb

And tried all of the suggestions on this post: https://support.mozilla.org/en-US/questions/1434503

What am I missing?

Cox.net is transitioning from in-house e-mail to e-mail handled by Yahoo.com. Our cox.net addresses are supposed to (and apparently have) transitioned so that they still work, but are processed through pop.mail.yahoo.com.

It is my turn to be transitioned and I have been successful in doing so to the extent that I can send and receive using my address(es) ...@cox.net through Yahoo web mail and on my Samsung phone. I have not, however, been successful in either sending or receiving mail using Thunderbird on my desktop.

I have been successfully using Thunderbird with POP settings for years with four different cox.net addresses. [I'm currently just trying to get two of them working -- unsuccessfully.]

I am using Windows 10 on a Dell desktop. I am using Thunderbird 115.9.0 (32 bit). I have reset the POP and SMTP settings as directed by Yahoo. One of the errors I receive is: "Error with Account .... Sending of password for ...@cox.net did not succeed. Mail server pop.mail.yahoo.com responded (SYS/TEMP) Server Error - Please try again later." It then asks me to retry or enter a new password. I have checked the passwords saved by Thunderbird and they are correct.

I suspect, that with all the Cox accounts being newly routed through Yahoo servers that I am not the only Thunderbird user experiencing this problem. Does anyone have any suggestions? Is it likely to help if I uninstall and reinstall Thunderbird? Would I loose all my mail, etc. if I did that? [I did the delete and add account in my phone and that was successful, but I wasn't concerned about losing mail there as it is all on my desktop.]

Thanks in advance. billb1111

Give that I use TB as my desktop client to access my nyu.edu email (provided by google), and that recently I updated my password as periodically requested by nyu admin When I try to access nyu email a pop up screen come up asking to authenticate with imap.gmail.com. I click next and get a 403 Access Forbidden error (Authentication failure while connecting to server imap.gmail.com.)

Solutions I have tried: 1. Clear cookies, history and cache on browsers and TB; 2. Changed default browsers (Ffox, Ch, Edge); 3. Deleted account in TB and created it again using instructions here https://www.nyu.edu/servicelink/KB0016473 4. Accessed my nyu email on browser to check user name and password. It works. I can access the email.

Nothing seems to work. Still get 403 error. As a result I am unable to authenticate and hence use the email account in TB.

I have the latest FF browser. I'm not using any proxy service, just spectrum connection. when i try to access my credit union account, i get this message

"Error: "WWF2TUh4dnM=" - You're using an outdated browser or are using a Proxy service which is unsupported. Please update your browser or turn off your Proxy to continue, thank you."

how can i get past this? All help appreciated!

I clicked the 'a' key on a folder in my email and a stack of emails disappeared. Some unread and some requiring a response! They're not in the archive folder.

Thanks!

I use a web application that lists items in a table, which provides a link to download the table as a CSV file. It used to work fine in previous versions of Firefox. However, in the current version, while the file save dialog defaults to a filename that ends in .csv and CSV is selected in the "Save as type:" drop-down, the data in the file that Firefox actually saves is in XML rather than CSV format. I don't know in which version of Firefox this behavior changed, as it's been a couple years since I tried to use this feature. Or I suppose it actually could be a new bug. I do know that when I use the same feature in Microsoft Edge, it saves the CSV file in the correct format, so this behavior seems to be peculiar to Firefox, rather than anything wrong with the web application.
