The Firefox Partitioned Engine Patch has been updated to 1.7, hot off the press.

1.7 is a bugfix, performance, and fluidity update. Therefore, changes should be felt in all three aforementioned areas.

For the best experience, installing with a fresh profile is recommended.

PowerUOC VI is ready, with a fresh coat of paint AND now boasting 95% to 100% compatibility with most Mozilla browsers across architectures! It should now work flawlessly on everything from a 400 MHz PowerPC G3 w/ Arctic Fox 27.9.16, all the way to a 4 GHz 28 core Xeon workstation w/ Firefox 72.

Enter PowerPEP, PowerUOC completely rebuilt from the ground up, designed to place an emphasis on only the essentials, while covering all the accoutrements via four specialized "engines", each one curated to churn out the absolute best delivery of their specialized departments.

And that's not even to mention the new additions included!

Needless to say, this is the most secure, compatible, and performant release ever made. Take it to town on every machine and OS you've got, and if you're impressed, tell everyone about it!

Let's make browsing faster, together!
