Thanks for Updating quickFilters!
the developer.

If you've found quickFilters to improve your Thunderbird life, please consider support quickfilters development through obtaining a pro license.

We can really use the support. Thanks again in advance.

QUICKFILTERS PRO HALLOWEEN SALE - starts October 7th

Please support the future of quickFilters and enjoy unlimited Premium Features. Install the latest version of quickFilters and then click the Buy License item from the quickFilters Pro tab on the Options dialog:

How to buy a license from options dialog

It's the easiest way to get a license as you get to select an email address for registration and delivery. If you prefer, you can also go to the web shop directly: FastSpring Web Shop

I have kept the process as simple and hassle free as possible, and you can use quickFilters Pro on as many Thunderbird installations as you like as long as it has your registered email address on it.

Your personal information will not be passed on or stored in a database by the shop. You can use quickFilters Pro on as many Thunderbird installations as you like as long as it has your registered email address on it. Also, the licensed email address is not given to any third parties or used for emailing you, it is only used for order fulfillment and license verification.

Renewals: The annual renewal is voluntary and typically costs 30% less than a new license. This way quickFilters can become fully sustainable and I can add new features and keep the add-on compatible with the modern versions of Thunderbird / SeaMonkey.

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!

Donate Instead

If you're not ready to support the quickFilters project through buying a license, you can buy me a coffee instead. Just note for this you will need a paypal account. The licenses (above) can be paid with other payment methods.

In US $:

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.
