Important news about the latest Thunderbird update (91):

The latest version of quickFilters supports Thunderbird 91; I did most of the conversion work myself, but got some help from John Bieling (Thunderbird Staff) converting the licensing / encryption module into an ES-6 module which is a more future proof method of encapsulating code.

quickFilters now communicates with the different parts and windows via a so called "background page", which is an invisible container necessary for mail extensions that don't just manipulate a content tab (a web page in a tab). This makes updates of different parts in the UI a lot cleaner and is able to better deal with multiple Thunderbird windows.

Localization: since version 5.3, quickFilters uses the new "json" format which has all translated texts in a single file for each language. These are all tested for validity when installing the Add-on so no more nasty surprises when you open a dialog in your language to be greeted by an xml:base error. Missing texts will simply be replaced by their English counter parts. Note that I am using google translate to generate these for cost reasons, but you can always drop me an email to suggest corrections and improvements.

As regards converting into a "native mail extension", there is still a lot of work to be done. There is no API method for things like toolbar / special commands in the filter list, so these have to still be covered in "experimental" APIs provided by the Add-on.

This also necessitates the Add-on asking for full permissions on install. We will try to find a permanent solution for this problem, but it may require a complete reimplementation of a lot of the code. Currently there is no support for user-defined toolbars by a natvie "mail extension", so this will also be subject to negotiating with the Thunderbird Core development team.

If you find any specific problems in Thunderbird 91, please report it here.

In order to support quickFilters transition into a full "mail extension" many methods of accessing the Thunderbird programming interface have to be recreated. Therefore please support the future of quickFilters by buying a license at the FastSpring Web Shop

quickFilters is fully compatible with Thunderbird 91.0 - which is the latest version of the new ESR period (starting August 2021).

Thanks for supporting quickFilters through your Premium License. If you want to buy me a beer as well, you can donate below - many many thanks!

Don't like paypal?

I love quickFilters - it makes working with filters a breeze! Yes! It makes me more productive so I want to buy you a coffee! Any Questions?

If you actually have donated already or only like freebies (yes, there is them...) you can also disable this page.

Do you suggest any amount?

US$ donations: we suggest 10$ as that seems to be be a what most people like to donate - but of course smaller and greater amounts are always welcome.
Euro donations: 10 Euros will be considered generous. Some people have given 50$ some 2$, but anything is welcome.

Your tip is important to make QuickFilters even more excellent!

But I don't like / never use Paypal!

Just send me an email, and I give you my address for sending a cheque or bank note.

What's the meaning of this free software ??

Free as in Free Speech, not as in Free Beer.

I think the most important aspect on free software is that it is a political statement to avoid the pitfalls of proprietary, monopoly driven software that coined terms such as "Embrace, Extend and Extinguish" and the innovation crippling model of patenting software (for further reading, please see links below). At the moment there is a conflict (I almost wrote war) between the old proprietary model of software and the Free Software Concept, and its you, the users who will really decide where the future will take us. By downloading the Mozilla products and extensions by independant software developers, like quickFilters, you are actively helping the cause.

The "free" Model
the free model.

As users, we like to use the software the way we want, and we more or less expect it to be free of charge. The question is what do the commercial software vendors make of this? Since the advent of facebook is a shift of users (and their data) from being the customers becoming the merchandise, and the corporations becoming the customer. This is because even the best community sites cannot operate without profit. The web is already overfraught with advertisement and data mining - The alternative is truly Free software that is funded by donations.

there is an excellent description of this concept here:

Quote: “Free software” is a matter of liberty, not price. To understand the concept, you should think of “free” as in “free speech,” not as in “free beer.”
Free software is a matter of the users' freedom to run, distribute, study, change and improve the software.
