Thunderbird 115 introduced a new look. I hate it. Not only does it no longer fit in with KDE Plasma, it lost functionality due to it’s new integrated search bar in the title bar.
So I went on a mission to fix it.
To restore the regular title bar:
Go into Settings > General > Language & Appereance and uncheck the Hide system window titlebar
To remove search bar:
Toggle toolkit.legacyUserProfileCustomizations.stylesheets to true in Config Editor (bottom of Settings)
Find your profile directory via Help > Troubleshooting Information > Profile Directory (or about:profiles in same page)
This directory should have lots of files e.g. prefs.js and places.sqlite
Create directory chrome
Inside that folder, create a file named userChrome.css with the below content:
#unifiedToolbar {
display:none !important;
}
Restart Thunderbird
Enjoy!
imo i liked the fact that it looked like Windows XP-era Outlook (not that i used it), i just liked the simplicity of it and the legibility. With 115 now it just seems poorly put together.
for instance, the buttons for messages have now moved to the pane where your accounts and folders are, Get messages is now just a little cloud icon in the left, and New message gets all the spotlight for some reason. it just looks like someone just slapped things together with no rhyme or reason, it’s inconsistent.
i liked the prior spaces update because you could just hide it into a little toolbar. Now they have a bar that when you get rid of it, it just messes with the position of the window buttons. not a good look imo.
it’s still a good client though.
