Thunderbird 115 “Supernova”
&gt; Our fastest ... ever<p>Last time I installed Thunderbird seems to have been in the  00&#x27;s sometime[0]. Since then I have used the same install, only updating it, and moving&#x2F;cloning  to other units.<p>Back then PCs  were  s-l-o-w but Thunderbird was _fast_. Moreso than Outlook&#x2F;Outlook Express in  startup as well as operation. Then, speed deteriorated bit by bit over the years. Due to feature creep, I suppose (in other news; also UX in several subtle ways that all add up).<p>I do not believe that the claim of &quot;Fastest  ...  ever&quot; is credible, and I have reason to believe that speed on an 13yo X86 unit still running 32bit[1] will not be impressive. Still, if speed is improved even slightly I&#x27;d welcome that.<p>[0] Datestamp of earliest email in a random folder  is  December of 1999 - 23 years ago. But then the earliest emails were imported from another email client into Thunderbird. In  any  case I started  using Thunderbird as a very  early  adopter,  mostly  due  to their very convincing  Firebird product (I was in Tech then, too).<p>[1] The unit I prefer using for anything that does not require Windows or other  ressource hogs (eg. browsing like now). Yes it&#x27;s _that_ old. It&#x27;s Linux, so no  problem.
