Hello,
I will change the splash screen from Thunderbird portable Version: 52.5.2 (32-bit)
How can i do that?
New: MBox Viewer (Mar 22, 2026), Platform 30.3 (Mar 29, 2026)

Our costs have risen a bunch. Please donate if you can!
You'll need to recompile the ThunderbirdPortable.exe launcher using NSIS Portable. Note that it can not be redistributed if altered.
Sometimes, the impossible can become possible, if you're awesome!
