Tab Mix Plus Now Requires Monthly Payment for New Versions

🚀 Tab Mix Plus is Evolving
Thank You for Your Support!

Our development depends on user support. In the past month, less than 1% of users contributed — which isn't sustainable for ongoing updates and fixes.

Tab Mix Plus has been a free and open-source Firefox extension for years, maintained through countless browser updates. But with donations falling short, sustainable development requires a small contribution.

Starting with version 1.32, Tab Mix Plus is now a paid extension to help fund ongoing updates and compatibility.

Price: $2 per month.
Need a lower rate? Just ask — we’ll reduce your payment to $1/month.
No subscriptions: We use a Trust Plan — you track your own payments, we trust your support.
Still open source: Tab Mix Plus remains open source — view, audit, or fork the code anytime.

We believe in openness — there are no subscriptions, no account creation, and no restrictions. Tab Mix Plus will always install freely, and we trust our users to contribute $1–$2/month to support ongoing development.

Version 1.31 and earlier remain free and compatible with Firefox up to version 139.

Your support ensures future enhancements and day-one compatibility with Firefox updates. If you value stability and continued development, please consider contributing.

Tested on Firefox versions 140, 141 (Beta) and 142 (Nightly)

Hey there,

It’s hard to believe, but it’s been 20 years since I launched Tab Mix Plus back in the early days of Firefox! My passion has always been to make your browsing experience smoother and more efficient by enhancing Firefox’s tab abilities.

But keeping Tab Mix Plus top-notch and evolving with web standards takes continuous effort. New features take time to develop, and Firefox changes require my attention all the time. That’s where you come in, my friend.

A small, monthly donation—think the price of your morning coffee—could make a world of difference.

Sincerely, thank you for your unwavering support. Together, let's keep Firefox a more awesome place to browse the internet!

Remember, every bit counts!

Always up-to-date

I am maintaining Tab Mix Plus since Firefox 1.0.
I continue to improve Tab Mix Plus by fixing bugs and compatibility problems with other extensions and themes, as well as other Firefox's based browsers like Zen Browser, Waterfox, Floorp and LibreWolf.

I regularly release new updates every 4-6 weeks to ensure that Tab Mix Plus remains compatible and functional with the latest versions of Firefox and other supported browsers.
