Update
Tab Mix Plus Now Requires Monthly Payment for New Versions
🚀
Tab Mix Plus is Evolving
Thank You for Your Support!
Make a Payment Special thank you for the 92 users who supported me with the amount of $476 in July 2025, which is encouraging, but my monthly goal to continue development is $3,000.
For 20 years, I've been the primary developer maintaining Tab Mix Plus through Firefox's constant
evolution.
With Firefox changing every month, I must release new versions monthly to ensure
compatibility, your support makes these day-one updates and future enhancements possible.
📋 More details about Tab Mix Plus support
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 — I'll reduce your payment to $1/month.
- No subscriptions: I use a Trust Plan — you track your own payments, and I trust your support.
- Still open source: Tab Mix Plus remains open source — view, audit, or fork the code anytime.
I believe in openness. There are no subscriptions, no account creation, and no enforced payments. Tab Mix Plus versions, including the Development Build XPI, will always install freely. I use a Trust Plan where I rely on my users to contribute $1-$2/month to support my ongoing development.
Version 1.31 and earlier remain free and compatible with Firefox up to version 139.
💬 Personal message from the developer
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!
