Display Thunderbird Email Attachments With Their Full Name

I'm not sure why the developers of the Thunderbird email client have made the decision to limit the visible characters of email attachments in the desktop email application. Attachments in the email client are displayed with a maximum of 14 characters in the beginning, a few dots and one character in the end. That's problematic if the file extension gets hidden by that, or if the user wants to know what file that is before double-clicking or saving it.
If you look at the example on the screenshot below you see that it is not possible to identify the file extension or full name of the email attachment. Sure, you can hover the file to see the full name of the attachment, but imagine having to do that not for one but for multiple files, every day.
The first thing that I did to find out if there was a setting for this was to look in the email client's options, but the results were frustrating. No option, not even in the config editor. Second best bet was an extension, and again the search was fruitless.
The last option was to make changes to the userchrome.css file to manipulate the display in the email program. And this works. Here is what you need to do.
Locate your Thunderbird profile directory on your computer system. You can check Mozillazine for detailed information on how to locate the Thunderbird profile folder. In short:
- Windows XP / 2000: C:\Documents and Settings\\Application Data\Thunderbird\Profiles\
- Windows Vista / 7: C:\Users\\AppData\Roaming\Thunderbird\Profiles\\
- Linux: ~/.thunderbird// or ~/.mozilla-thunderbird
- Mac OS: ~/Library/Thunderbird/Profiles// or ~/Library/Application Support/Thunderbird/Profiles//
Now that you know where the profile folder is located you need to open it in a system file browser. Locate or create the chrome folder in the root Thunderbird profile folder and locate or create the file userchrome.css in there. The easiest way to create the userchrome.css file is to create a simple text document and rename it. Ensure that the file extension is .css and not .txt.
Open the file afterwards and add the following line to it:
#attachmentBucket, .attachmentBox {min-width: 25em;}
The important parameter is 25em at the end. This defines the width of the attachment area for each attachment in Thunderbird. Depending on the attachment names you get you may want to increase or decrease the value to make the box wider or smaller.
You need to restart Thunderbird before the changes become visible. As you can see in the example from my system, the email client now displays the attachment's name in full.

You said that Outlook isn’t your main email client, so which is your main one?
I think its thunderbird
It is Mozilla Thunderbird.
Awesome! This actually solved my problem… what a stupid bug.
If this is the same bug that I’ve encountered, there may be another fix: (1) hover over open Outlook item in Taskbar, cursor up to hover over Outlook window item, and right-click; (2) this should give you Restore / Move / Size / Minimize / Maximize — choose Move or Size; (3) use your cursor keys, going arbitrarily N/S/E/W, to try to move or size the Outlook window back into view. Basically, the app behaves as though it were open in a 0x0 window, or at a location that’s offscreen, and this will frequently work to resize and/or move the window. Don’t forget to close while resized/moved, so that Outlook remembers the size/position for next time.
THANK YOU Claude!!! I could get the main window to launch but could not get any other message window to show on the desktop. You are my hero!!!!
Solved my issue! 6 years later and this is still problem…
Fantastic. Thank you. Size did the trick.
This solved my Outlook problem, too. Thank you. :)
Thank you so much, this started happening to me today and was causing big problems. You are a life saver, I hope I can help you in some way some day.
You are a god – thank you!

Yah…thanks Claude. I’ve been having the same problem and tried all the suggestions…your solution was the answer. It had resized itself to a 0/0 box. Cheers

Thanks a lot for the article. Don’t know why it happenend, don’t know how it got fixed, but it was really annoying and now it works :-)
Thanks a lot. I was facing this issue from past 3 week. I tried everything but no resolution. The issue was happening intermittently and mainly when I was changing the display of screen ( as i use 2 monitors). The only option i had was to do system restore. But thanks to you.
I’ve been tried to sole this problem for 12hours. Your comment about changing the display of screen helped me a lot!! Thanks!!
Thank you…don’t know why this happened but your instructions helped me fix it. Running Windows 10 and office pro 2007

This problem was faced by only one user logging to TS 2008 r2 using outlook 2010.The issue was resolved.
Thanks.
Great tip. Thank you!!!! If it helps, I had to use the Control Key and the arrow keys at the same time to bring my window back into view. Worked like a charm.
Thank you, this worked !!!!
