Thunderbird Support Forum

Dear support,

I installed recently Thunderbird 115.5.0 (64-bit) on my laptop running Debian 12.

I have a problem with the font size settings in the message view.

By default, the font size is very small. I can increase it by tuning in the top Menu. Tuning the Font size to 26 pt I get a readible text, see Picture 1. When I move to the next message, the font size becomes small again. Picture 2 shows when I moved and came back to the same message. The menu is shown, and the Font Size appears to be 26 pt in both screen shots.

I have set layout.css.devPixelsPerPx to -1

I have a userChrome.css, but it does not fix the font size in the message view. I wish I could know how to do that!

Thank you in advance for your help! Eric CM

Thunderbird will no longer save sent emails to my SENT folder. I get an error message when I send an e-mail saying, "Your message was sent but a copy was not placed in our sent folder(Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent-using my email address. Cox Communications is my ISP and they say the problem is not theirs.

Need to set up Thunderbird to receive emails from yahoo. Cox is transitioning emails to yahoo presently have two addresses : cliven@cox.net and daciaandclive@cox.net

I have spent the last TWO HOURS trying to find an answer to what should be a simple problem, and it seems not to exist!

I need to find out WHERE Firebird lists my email account PASSWORD.

I do NOT want to reset my password.

I simple need to know WHAT my password is, and since I set up the account [actually a few accounts] several years ago, my notes are evidently null and void, because none of those passwords seem to work.

My email is through verizon.net, which is one of the problems because they gave all of their email coltrol to AOL, which thouroughly sucks, and they seem not to have anyone who speaks fluent English who can assist me in FINDING the current password!

If ANYONE can help, it would be most greatly appreciated!!

I have a friend who has been using the Outlook email client with her Gmail account. She's looking into moving to Thunderbird. Is it just a matter of... - making sure that IMAP is enabled in her Gmail account - installing Thunderbird - adding the Gmail account and credentials to Thunderbird

She's got lots of folders so is concerned that they won't be lost in the process.

Version 115 is absolutely horrid! I was surprised recently by an apparent automated update and it has thrown off my email routine enough to seriously consider changing clients. The user interface is unusable, folders are disappearing from view, and is aesthetically a mess. As a 10+ year user of Thunderbird, I'm going back to 91 or will find a new product...

I use dark mode (Windows 10 Pro, Thunderbird 115.4.2 (64-bit)). Fresh installation, fresh profile. When I reply to some emails, the reply text is not visible. The examples I saw were with a light (white?) background, but I'm not sure if it also happens with other backgrounds. But it's not all white backgrounds either, some emails with a light background I can reply to just fine.

The reply area can be dark with a dark grey font (slightly different color), or it can be white with a white font. In both cases, obviously the text I type is not readable.

Any idea how to fix this?

Every year I am required to update my university's net id password. Normally T'bird responds asking for a password update. Not this year; I am just cut off.

I followed all instructions from the T-help site. But it is impossible to update the "saved password." "edit" is not allowed.

When T-bird did ask me to connect via Google, see the screen shot, the next screen locks with a 403 error message, also attached.

I would like to continue to use Tbird, but this is making it impossible. My university's IT people had me download the T-bird again, but the problem persists.

Please advise soon.

Hi, since I use a set of different browsers for different tasks, it would be great if there was an easy way of opening links from within thunderbird emails to your browser of choice. E.g. via right mouse button: Open Link in ... I use that method in other applications frequently.

Kind regards

I am getting a non-overridable TLS error when Thunderbird opens or when I attempt to download new emails (the emails will sometimes download later after I force a download. I have tried to change my TLS version without success. Please help me solve this issue.

My email setup is to an IMAP server (POP will not work with Gmail.com accounts). See my attached image files for further information.

Hi when I uninstall TB and re install it still has old accounts info. I want an empty TB to then bring in new accounts / email accounts

Many thanks steve

I have over 200 emails that I can find in search and can view a preview type showing of emails, I can right click or take any action aside from clicking to open email. But when I try to open email it seem to open a new page that is blank and shows a page just like regular email listing but the field showing emails in blank. This same blank results also happens when I can see emails in search window but click the link to view in list view. I just need to open an email enough to be able to see what email address the original email was sent to. I also will add I cant seem to find any of the emails found in search in any of the accounts that being used in Thunderbird (accounts listed in left side column) Also these emails are 2 years old and the computer may or may not have had a OS reset during that time but not sure.

I just got the new "supernova" update and now I can't find the stettings to place my tabs bar at the top of the screen. The old version had the tabs right at the top, just as a browser would typically have it as well (see new and old schreenshot for comparison). But I'm just unable to configure it that way.

Can anybody please tell me how to configure thunderbird to use all that wasted space at the top sensibly?

Cox has tranferred my email accounts to Yahoo. I need to know how to connect back to Thunderbird. Had a discussion on your FB group with ANJE YELF.. She said to leave a message here and she would get back to me on how to do that. I have imap.

On opening Tbird I have started getting a Google pop up asking me to sign in to Google to continue to Tbird. This is just annoying as I can access all my email accounts without signing in to Google. I just have to close the annoying pop up every time I open Tbird. How can I stop this happening?

After decades of using Thunderbird it has amassed contacts. Even for my own contact it saves a contact like "lynn@szetosolutions". incomplete email addresses, or associated with DMV...just for my own email it has saved 7 versions and or affiliations. I want to clean up and remove the excess, inaccurate email addresses that keep auto filling my emails and reduce the constant annoyance. Can someone help me? I'm so grateful for any help.

Since the big update I cannot read my messages in the message window without scrolling as I read each line. The message window is so small that I can only see about four lines of text at a time. I can't get the messages to open in a new window unless I click on them and choose "open in new window" even after setting them to open in a new window on their own.

The last update fixed the font on everything from being too big in spite of settings so now I can read a little more at a time. It's still very frustrating having to scroll constantly.
