From my old HD (Ubuntu 16.04) I copied ~/.thunderbird and other programs to the new disk with Ubuntu 18.04 installed.
All went good.
I tried to install Opera. The installation was unsuccessful, a window asking something was held.
After that Thunderbird Local Folders -> Inbox (only) was invaded by large icons like this screenshot
enter image description here
Flowers, plants, trucks and others.
I restarted but those images are still there.
Opera was successfully installed. What can I do to remove them?


This fixed it for me:

sudo apt-get install fonts-symbola

but turns the icons b/w!

From https://ubuntu-mate.community/t/thunderbird-with-huge-icons-emoticons-mate-18-04/16249/23

Here's a way of getting colored icons:

sudo apt-add-repository ppa:eosrei/fonts
sudo apt-get update
sudo apt-get install fonts-twemoji-svginot

I did not have to uninstall fonts-symbola for this to work but I don't know how Thunderbird decides which to use.

    remark: the issue goes away, and so does your colored emojis! (they are the right size, but black and white now). Would be nice to be able to keep colored emoji... – Sulliwane May 12 '18 at 20:32
  • @Sulliwane thank you for pointing that out - I hadn't noticed! Have edited my original answer to include a color font. – B.Tanner May 17 '18 at 16:57
  • i like the message: Only Mozilla Firefox/Thunderbird currently support the SVG-in-OpenType font format required to display these fonts in color. All other applications will display the included backwards/fallback compatibility B&W outline glyphs.

  • and I need to say, this that this font hurts my eyes somehow .. need to play around with the settings in thunderbird .. – rémy May 29 '18 at 7:15

    I like black and white - it's less intrusive. So the first line only helped me already. Ideally, I'd find a way to block these things from appearing in subjects completely. – Alexander Engelhardt Aug 29 '18 at 7:07

While not a long-term solution (but should work until the fix for the bug is deployed), you can install the EditEmailSubject add-on for Thunderbird. It will allow you to delete offending characters from message subjects.

I find the add-on useful generally so this works for me.


To fix this I downloaded the


from here: https://github.com/googlei18n/noto-emoji/tree/master/fonts

and copied it to


(sudo was required)

then restarted Thunderbird and everything was fine.
