Dear support: My O.S. is Ubuntu 16.04 MATE. Since an upgrade last week thunderbird crashes as soon as I open it. After some days fighting with it I've discovered a possible cause: It happens when I try to display a message with certain characteristic, I suspect it has something to do with unicode special characters. When such a mail is displayed, TB child process dies causing then mail program to crush as well. The versions of TB I've tried are 68.10.0 (64-bit) and 91.1.1

Today I tried to send an e-mail using my signature and the problem manifested again. As soon as I disablepears my signature the problem disappears. This is the signature I was using: <style>

   #firma *	{ color: navy; font-size: 10pt; font-family:"Arial","sans-serif"; }
   #firma p	{	margin:0px;  }
   #firma span.nombre { font-weight: bold }
   #firma span.puesto { font-style: italic }
   #firma span.y { display: inline-block; background-color: yellow; width: 7px; height: 15px; }
   #firma span.b { display: inline-block; background-color: #000080; width: 21px; height: 15px; }
   #firma span.logo { font-size: 11pt; font-weight: bold; color: #000080; letter-spacing: 1pt; margin-left: 5px;}
   #firma div.address p span { font-size: 9pt; color: #787777; }
   #firma span.var { display: inline-block; text-align: center; width: 13px; margin-right: 5px }

Are you using the vanilla version of Thunderbird from or the one provided by your distribution? In the latter case you should ask in a support forum for your distribution.

Thanks for your replay, christ1.

Version 68 is the one provided by the Ubuntu distro. Version 91 has been directly downloaded from; so I am using both with the same result.
