Why in Thunderbird or in any other known email client software, do I have to create a new email using "forward" or copy-paste, in order to resend an email that for some reason, like the destination server mail was down, did not reach the destination and has to be resend again? Why not create an option or a button for "resend", that just repeats the email and sends it again to the destination email addresses? It seems a basic option that should exist in every email client software, but unfortunately it does not exist.

I looked through the help files but still have no formatting toolbar when trying to create my signature in order to format the font, color, ...etc. I set me messages to be sent in HTML and checked the box in Account Settings to use HTML too. I can type my signature content but there is no formatting bar at all. I'm using the TB new beta 60 version.

I'm new to Thunderbird so this is pretty basic I know, but? I want to set the font style, size, and (color although that doesn't seem to be an available option) and make them my default for all newly composed emails. Any help will be appreciated. Thanks.

Before the Thunderbird 45.0 update came through, I used to use an ad-on called TT DeepDark. Since the update, I get an error message telling me that this add-on is not compatible with version 45.0. Because of a visual impairment, I depend on dark themes so that I can read more easily. I thought at first that it was something with that one individual add-on, so I searched for one to take its place. However, it appears that no theme add-on available through Mozilla is compatible with the latest version. Is there any kind of time frame for when this might be fixed?

I do know that things often depend on individual developer, but since every single theming add-on is currently nonfunctional, I know it isn’t something like dependent on an individual developer.

Is there any kind of workaround in the meantime? I really depend on that dark theme so that I can use Thunderbird more effectively.

I was wondering if Thunderbird can play an mp3/wav song as the e-mail alert or is it restricted to just a maximum 5 second sound file? I installed Tonequilla and tried some of the sounds that came with that but TB would only play the smaller files so I am guessing there is a restriction. I am using TB v 52.7.0 in a linux environment but I have also have V 52.7.0 on a windows xp computer as well. You already know this but when you browse for sound files from within TB it does not recognize mp3 files only WAV and OGG the other aspect is that WAV files are enormous in comparison e.g in the attached image there is an extract from a song The Brightest Star. TB plays the OGG file but will not play the MP3 or the WAV and the WAV being uncompressed is significantly larger. I also installed Mailbox Alert, there is a Command feature in that and I was wondering if that can be programmed to launch and play an MP3 track as an alert although I would be at a loss as to what commands to put in there. Thanks for your time.

Made a mistake by changing user_pref("layout.css.devPixelsPerPx" from I think - 0.5 to +0.5 as incoming emails font was miniscule, but made nor difference... so thought it may be a font size, so changed to 12.... Now ginormous and unreadable. Searched through pages here for an answer and got to the prefs.js folder to find this file but it is not there.... I searched with notepad edit search for "layout" but no luck. Any ideas anyone? I tried adding the line user_pref("layout.css.devPixelsPerPx", "1.5"); whilst TB was closed and then opened TB but had made no difference.. :-( Any ideas anyone? TIA Graham

We have multiple email accounts. How do I make one of the accounts the default sender address when we Send to a document to Mail Recipient? Or how can I change the order of the email accounts on Thunderbird that they appear?

On my old small laptop I wanted to increase interface font size. Erroneously thought that in layout.css.devPixelsPerPx I could insert the desired font size. I have inserted 12, now Thunderbird is unusable, some giant menu words appear but I cannot move anywhere. Can I I edit a configuration file manually to reset to a readable size? Which?

I was happily typing along and noticed both a typo and the fact that the typo was NOT underlined in red squiggles. Hmmmm, I thought.

Fiddling around, I discovered an option on right-click that allowed Me to turn on spellcheck. Now, every time I type in an email or forum, on Twitter, anywhere, I have to right-click to be sure of My spelling.

Thus began My efforts to find how to set the button to be on by default... Finding none led Me to "Help," which a search of the term "spellcheck default" led Me to a zero in returns. Sure, there were discussions with those terms, but I could not prowl them all looking for the method of setting spellcheck to be on by default. The first few pages yielded nothing...

So if You would please, direct Me to that function. [smile]

Thank You.

All of a sudden, I can't see emails that I know are there because the subject of a previous message in my inbox is underlined. I can find the emails when I search for them by putting in a recipients name. And when they show up the thread column exhibits a red flag (don't know what it means). HELP.

Hi all,

I am using FiltaQuilla (add-on) in Thunderbird to save the attachments of received e-mails (filtered on domain, e.g. "@example.com") to a specific folder for each sender. But for some reason, all saved files are empty. The file name is correct, so all attachments seem to saved, but without their content. I checked the attachments in the mails: they are not empty files.

I've added a screenshot of one of the filters (my apologies, but it's in Dutch). A little translation: Filter: - From, contains, @example.be Actions: - Move message to, VERWERKT (other folder in mailbox) - Save attachments to, C:\FTP\...\...\MAIL_IN - Mark as read

This is a very weird problem, and I cannot figure out the cause. All help is very much appreciated, every hint might get me on the trail to the cause and solution!

I use an translator extension for firefox for russian so I do not need this integrated tool and it's annoying to see it everytime I open a russian page. Please help me, I don't know what the source is of this translator but I can tell it's not from an extensions as I deleted every extension and tried, not worked.

I want to send bulk mails as bcc to all the recepients. On adding the mail ids from the address book all are being added as `To` and so I am forced to change them to bcc one by one. How can that be done automatically instead?

When I download an image in Firefox and open it from the downloads folder it will always open in Pixelmator not Pixelmator Pro.

If I double click on an image file elsewhere they correctly open in Pro, but in Finder, the icons are for Pixelmator not Pixelmator Pro. This can be hidden if I turn on finder icon previews, but selecting Get Info always has the Pixelmator icon not the Pixelmator Pro one.

Im not sure if this is a macOS problem, a firefox issue or a Pixelmator bug but it seems to be related to the way the files are registered.

Things I have tried:

Changing file associations in firefox. Rebooting Changing the open-with properties in finder: Open all with Pixelmator Pro Reset the Local & User domains with lsregister lsregister -kill -r -domain local -domain user -domain system -v

Firefox has started making a piercing high-pitched screech when the "save image" and "file update" panels appear. This is a confirmation or alert sound I suppose. It occurs when saving an image from a right-click menu and when downloading a file. Formerly Firefox used the system default sound for this, and that sound is still working in other programs for similar operations.

How can I fix this? Or alternatively how can I disable the sound during such operations in Firefox (or alternatively system-wide)?

Thunderbird recently updated to 60.0 and now I cannot install themes. None of the help threads I have found work. I must be missing something. Everything I try keeps adding themes to Firefox instead of Thunderbird.

I just upgraded to Thunderbird 60 and wish to use Google Search as the default search engine. I installed the Google Search for Thunderbird addon, and restarted Thunderbird, but Google Search does not show as choice in the search-engine list. Am I missing a step?

I have researched endless options how to download an add on for google search in the options dropdown menu for search engines.

The download https://addons.mozilla.org/en-US/thunderbird/addon/google-search-for-thunderbi/?src=search says it is not compatible with my version of thunderbird which is 60 Beta. What must I do?

See the previous, now archive post about it.

If this option makes emails sent from Thunderbird to any other email client have arbitrary line breaks where the line changes in the view of the composer. Please explain to me like I am 5, why is this ON by default? I just spent hours wording and formatting a work email vital for my career just to find out it will most likely look like a poem to the person that reeds it. This mailnews.wraplength "feature" looks a lot like is there to signal to other non-Thunderbird users to use Thunderbird. I really really hope there is a good explanation for why `mailnews.wraplength` exists and is on by default.
