Authors/Port authors:

Mozilla Thunderbird is a redesign of the Mozilla mail component, with several new features and improvements to make your mail and news experience better. It integrates chat client and, since version 38, a calendar application.

This software is distributed as compressed package. You have to download and manually install it; if prerequisites are required, you will have to manually install them too.

Manual installation

Program is distributed as ZIP or 7 ZIP package: download to temporary directory and unpack to destination folder (delete files from previous versions). See below for download link(s) - calendar-timezones-2.2016c.xpi is a fix for Lightning integrated in Thunderbird ver. 38.8.0 beta 7.

  • Before starting the program, it is useful to set mozilla_home in Config.Sys file, to preserve profile and plugin directories and make program upgrades easier. For example:
  • To run at the same time Thunderbird with Mozilla or Firefox, use Run!: copy RUN!.exe in Thunderbird's installation folder; rename it as thunderbird!L.exe and use this one to start the program.
  • You can load XUL.DLL in high memory using Highmem.
  • Find at the dictionaries and language packs for Thunderbird (select the language you want, then at the bottom of the page choose "Version information" and click on "See complete version history"). You need to modify general.useragent.locale setting in the "Configuration editor" from en-US to your locale.

You can install the prerequisites with rpm running the following string in a command line:

yum install libc freetype fontconfig pthread mmap libgcc1 libstdc++6 nspr
