Latest News (22/10/2021) - Thunderbird 91 Compatibility

quickFilters 5.3.2 is fully compatible with Thunderbird 91. In rare cases there may be problems when updating from older versions of Thunderbird, see their bug 1732515. If there are issues after installing or updating, please read the instructions here.

Why did quickFilters go Pro?

In order to support the ongoing improvement of this mail addon, I have decided to offer a professional version of quickFilters in which some additional "power" features will be added. This is necessary as my country of residence just got so expensive due to additional taxes (water, house tax) and my wife had to give up her job as nurse due to health reasons. I am still investing a large portion of my free time to the development of addon code in the mail sphere and I would like to continue doing so in the future.

I have decided that the best way forward would be to use the freemium model which offers two versions, one for free which has standard features and shows the donation link whenever the software is updated and a registered professional version which asks for small fee in order to fund development and support.

Please support the future of quickFilters and enjoy unlimited Premium Features. You can purchase a license from quickFilters options, using the quickFilters Pro tab. It's super easy and helps future proof this Add-on. You can use quickFilters Pro on as many Thunderbird installations as you like as long as it has your registered email address on it.

You can buy a license directly from the quickFilters Pro tab in the settings dialog: How to buy a license from options dialog
If you prefer, you can also go to the web shop directly: FastSpring Web Shop

Version Details

All dates are displayed in UK format: dd/mm/yyyy - you can request any version that is marked as not released or any old version listed; simply send me a personal email from the quickFilters Options dialog, on the Support tab - [(Jump to Screen Shot)].

Thunderbird 68 support ended on thunderbird.net

Unfortunately thunderbird.net does not accept updates for legacy versions anymore - they only support the new "Mail extension" format and our "mail extension with experimental APIs" which is a workaround for missing advanced features.

From of version 4.6 forward you have to install such legacy versions from the github releases page.
