I have installed Thunderbird 102.3.0 as snap version on Ubuntu 22.04. Until now I had the .deb version. There I could create a new userChrome.css file and with it I could for example enlarge the profile picture of the sender. Under snap this no longer works. What do I have to do?
You’ll have to add the file in the
.thunderbird folder located in the Snap’s home directory (different to your user’s home directory). The path to this is:
until now I had in the directory home/stefan/snap/thunderbird/common/.thunderbird/sywxb570.default/ folder chrome and in it the file userChrome.
Neither moving the folder nor moving the file to the parent folder ./thunderbird did the desired result.
