Count down, timer and random dynamic text for Thunderbird signatures

Some weeks ago, when planing my this years holiday I searched for the possibility to create a signature for Thunderbird that contains a count down and a random dynamic text – without success.

So I decided to write the little external AddOn "MB-DynamicTextSignature for Thunderbird", that fills this gap – an AddOn, that allows to add

  •  timer
  • count down and
  • random dynamic text

to your HTML signature in Thunderbird.

Have a look at
for a detailed description or download the installer from

"MB-DynamicTextSignature for Thunderbird" is freeware for non commercial use and currently in beta state.
