Thunderbird not updating vista

When messages are composed in paragraph format, "body text" and split mail quotes are converted to paragraphs when pressing the enter key.

Mozilla Thunderbird makes e-mailing safer, faster, and easier with features such as intelligent spam filters, a built-in RSS reader, and quick search.Thunderbird was designed to prevent viruses and to stop junk mail.This security code is sent to your registered mobile phone or alternative email ID.Recently Microsoft enabled this in its Gmail service since long time.No other applications on my System were slow and the notebook has afast harddisk and SSD, so this was not the problem.

The following steps helped me to speedup Thunderbird so that it got usable again.

Various improvements in the Thunderbird themes on all platforms, especially for Windows 10.

Fixed: Unwanted inline images shown in rogue SPAM messages.

Set some interface options Edit Thunderbird options under Preferences → Advanced → General tab, click on "Advanced options" button and set these values: and gfx.direct2d.disabled = false and restart Thunderbird.

If it is still slow, try the next options: Disable Aero Glass Disabling the Aero Glass interface makes the interface reacting much faster.

I've experienced that Thunderbird has gotten slower and slower on my Laptop, at last it was nearly unusable.
