Thunderbird Community Forum

Hello; I have been using Mozilla Thunderbird for many years on my PC and was wondering if I can start using my account on my Ipad or Iphone as yet?

          Regards

1. Where can I find the release notes for Thunderbird versions?

2. I mistakenly installed v148.0 from the release channel, when I really want the ESR version. This article says, " "Still unsure which channel to use? Start with the Thunderbird Release channel. You can always switch later if your needs change." and this thread says that one can perform the necessary downgrade by simply deleting the compatiblity.ini file from the profile folder. However, the current release channel version (149) and the version I have installed (148.0.1) are far ahead of the ESR version (140.8.1). I have already configured 8 IMAP accounts and 4 add-ons and would like to retain my existing profile. Can I simply downgrade by deleting the compatiblity.ini file from the profile folder or do I risk data corruption due to changes to the data structures? Can I simply install ESR 140.8.1 over 148.0.1 or do I first need to uninstall 148.0.1?

Athough you advertise Thunderbird as a free product, your website does not allow me to download it unless I first pay. I am unwilling to pay until I have been able to test the product and verify that it will do what I need it to do.
