The 'Message Header' is the area above where the message content of an opened email is displayed. It typically contains a set of buttons - Reply, Forward, Archive, Junk, Delete and More It shows From, To, Subject and Date It may show other information depending upon settings and type of email.

Do you find the spacing between eg: the 'From' line and the 'TO' line is too much? Do you want to reduce this gap? If yes, then the following information may solve your problem.

I have 4 accounts in Thunderbird all with both incoming and outgoing servers set up and under account management they should all be using there individual SMTP accounts but no matter which one I send with it only sends from the default account which is creating all sorts of delivery problems. How do I delete the default account so it sends from the individual smtp accounts like it should do

I had an issue with one of my domain emails hosted at ionos so I removed one of my domain accounts and reinstalled it I let is set up with default storage diorectory user/appdata and so on then went to sever settings and changed the local directory to the hard drive my other emails are stored on the only thing is I'm missing all the folders in the directory but my emails are still working. does any one know how I can fix this as I said I have already tried to remove the account and reinstall it and it still come up the same i have included an image of both accounts hosted at ionos not that that should make a differance where its hosted just that they should look the same in the directory!. thanks to any one who could shed some light on this. as you can see there are folders in one but theri missing the ones on the right. shame there is no little app from mozilla that can fix issues like this in thunderbird it would solve so many little issues that seem to pop up now and again.

I have been getting this error message for over a week now, PR_END_OF_FILE_ERROR. My internet is fine and I have restarted my computer a few time since the problem started. I have added some sites to the Exceptions list but even then they don't work properly. I have tried refreshing Firefox and changed the profile and they both didn't fix the problem. I am sadly not knowledgeable enough to make sense of the Web Developer Tools. The attached image is what my YouTube page looks like after add the site to the Exceptions list.

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

Hi all.

Why did Mozilla move to an update that doesn't work?

115.5.1 update. Thunderbird not accessing email servers.

Thanks for upsetting a system that worked. Why?

It might look very swish - but it doesn't work and if and when it does I'll need another weeks course to find out how it works interupting my well versed routine.

Thanks.

So to cut it short, i have an issue with not just firefox but almost all other browsers too. I have tried Firefox, Chrome, Opera and Edge. Both Firefox and Chrome will instantly close when i open them. As in, the window will open and immediately close after barely half a second. This has happened with Chrome and Firefox, yet Opera and Edge dont seem to have this issue. I am a Firefox user normally so this does make it a little annoying. Any ideas on why that is?

I can't download anything anymore. I get the "failed" message. I see in support questons that this has been going on for a long time even though there have been repeated "fixes" reported. I've used Firefox for a long time and really prefer it, but I'm having to change to Chrome to be able to complete my work.

Ok well i went to about config and tired off all the accessibility about the quick help bar and now my question is every time i try to go to google search and click on shopping no matter what item i am searching for I get a pop up at the the bottom i of the page every time i hit on shopping that say error update can not be added to this list or some thing like that. it was ok until the last update o of firefox and since i did that but am not sure why. doe not do it in Chrome just frefox. firefox is getting to the point b where i an thing king of leaving it. Thank you tried a scree n shot but it does not sty on long enough '

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

Running Firefox 120.0.1 on Windows 10. I also run Vivaldi and test with Chrome. I installed Google Analytics Opt-Out add-ons on FF, Vivaldi, and Chrome. When I go to any site with links to X (Twitter), and click on the link, instead of that link appearing the last X link I went to appears. If I click again I get to the correct link.

When I disable the Google Analytics Opt-Out add-on all works fine. This doesn't happen with either of the Chromium browsers, so I'm thinking there's something happening in Firefox by avoiding Google analytics that isn't in the Chromium browsers. In addition, this behavior began within the past couple of weeks of recent FF updates.

I installed several different Google Analytics add-ons and the same thing happened in FF, but not in the Chromium browsers.

Any ideas? I know I can disable the analytics crushers but I really don't want Google hijacking my browsing.

Stop tabs from automatically refreshing to top of page. Many people have this problem and I don't find a fix. One article states to go to Options and "Warn me when websites try to redirect or reload the page," but I can't find options.

Hi. Recently Thunderbird automatically updated(current version is 115.5.1 32bit) on my win 10 Pro 64bit (v22H2) desktop, and now most of my accounts have a problem. My GMAIL account is the only one that I can both receive and send mail from.

Both Outlook accounts can receive mail, but only one account can send. Both accounts have exactly the same imap & smtp settings. Both have Authentication set to normal password. The account that cannot send mail fails login, the popup window suggests this is a password problem, but no password I have works. (this includes 2 MS generated App passwords).

Most importantly, my main Yahoo account cannot send or receive mail. I will just focus on this one for the time being. The 2 error messages I get are:- 1. "Connection to server export.imap.mail.yahoo.com timed out" (after several minutes) 2. "Sending of the message failed. The message could not be sent because the connection to outgoing server(SMTP) smtp.mail.yahoo.com timed out. Try again" (after several minutes).

Here are things I`ve tried.

Disabling the ipv6 setting using config editor as suggested here https://support.mozilla.org/gl/questions/1401034 Changing the timeout mailnews.tcptimeout with config editor as suggested here https://support.mozilla.org/bm/questions/1367042 Logged into my yahoo account through browser using email address and password. Deleted all app passwords for TB. Waited 24 hours. Logged back in to check changes had taken. Generated new app password, and took copy of it. Checked with yahoo that the spaces in the password should be removed. I deleted the Yahoo account from TB, and re-installed it, both with the automatic configuration TB uses, and the manual configuration method. Despite TB asking for a password (I supplied the newly generated Yahoo App password), there is no password for smtp, imap or OAth2 stored in the saved passwords within TB.

I have checked the imap & smtp settings against these https://help.yahoo.com/kb/manually-download-yahoo-emails-sln28681.html, and used OAuth on both incoming & outgoing. I have also tried these settings with Authentication set to normal password. I have tried these settings https://help.yahoo.com/kb/SLN4075.html with OAuth2, and with normal password.

I have previously temporarily turned off Avast free antivirus, as well as Win 10 firewall. Since there is activity on some of the accounts I`m assuming the problem is not this. I have also previously loaded windows in safe mode with networking, and that did not make a difference.

Outlook on my Android has no problems sending or receiving from any of these accounts. I can find no useful info on the net with regards to problems after updating, but refuse to believe I am the only one experiencing problems.

After 3 days I have run out of patience. I have exhausted information and options. Can somebody offer suggestions? Thanks in advance, Dave.

I am using Firefox version 119.0.1 (64-bit) on Ubuntu 22.04. Using this version of Firefox, as well as previous versions for the last few months, I am having a persistent error when using Google Advanced Search. I enter search criteria into the field “Find pages with … all these words” and successfully progress through a chain of web pages. Previously I was able to backtrack to the previously mentioned field and find my search criteria, then edit the text, and carry out a modified search. For many months this field has been blank when returning to it. So it is now necessary to re-enter all text for a new search. This is very frustrating. I have experienced this problem on the three computers that I regularly use.

I have found that when I use the Google Chrome browser the problem goes away and searches progress normally. I would much prefer to use Firefox as my browser as I find its bookmark system superior. The truth is that if this problem with Firefox can’t be fixed soon I will be forced to migrate to Chrome. Can you please help me resolve this Firefox problem?

Hello Mozilla Support,

I have a streaming app's website, and I'm encountering responsiveness issues. The site doesn't seem to be displaying correctly on different devices. Could you provide guidance on how to improve the responsiveness of my website? Your assistance would be greatly appreciated.

Thank you,

Whenever I open Firefox, it opens every tab from my previous session. I don't want this - if I closed the window, it was because I wanted it closed, and I don't need any automated system to re-open everything on the off chance I was wrong. I believe the setting for this is on the General tab, but as you can see in the attached screenshot, it's definitely off, yet the feature won't go away. I also tried changing the config settings, as listed here:

https://askubuntu.com/questions/1285172/firefox-always-restores-windows-and-tabs-after-reboot

, but it had no effect.

How do I stop Firefox opening these tabs without permission?

The Firefox "New tab" page shows quick-navigation buttons. At the top right of each button, the 3-dot menu has an Edit option. On the edit dialog is a link "Use a custom image", which then prompts you for a image URL.

I've tried pointing this to images in my Google Photos (a 1024x1024 .JPG), using an open-shareable link, but it doesn't work.

a) What format does the icon image have to be in? b) Are there any limitations on the URL? c) Is there a way to use a locally stored icon image?

Any guidance would be most welcome! Thanks :)

I just updated my Firefox browser. Now it doesn't work: "tab is crashed" - an endless chain, always again this.

You should try harder to release bugfree software ...

What about short-time help?
