Momiji web browser

If you have an older Mac that’s still perfectly usable, as most older Macs still are, then you might be interested in running a modern web browser on that Mac, and that’s what Momiji is for. Momiji is based on Firefox, so it includes up to date security patches, and support for modern web browsing features and capabilities.

The Momiji web browser brings a modern browser with support for OS X Lion 10.7, 10.8 Mountain Lion, 10.9 Mavericks, 10.10 Yosemite, OS X 10.11 El Capitan, MacOS 10.12 Sierra, MacOS 10.13 High Sierra, and MacOS 10.14 Big Sur, which covers a lot of Macs built all the way back in 2007.

If you’re not familiar with downloading apps from Github, go to “releases” and then download the most recent DMG or PKG installer file. While Momiji is open source, you most likely do not want to download the source code.

Having a modern up to date web browser on an older Mac can be the difference in continuing to have it be a usable computer or not sometimes, particularly if a critical site is not compatible with the older browser. And that’s really what makes apps like Momiji so useful, allowing you to continue to get usage from an older Mac, even if Apple has long ago stopped supporting it, and every other major browser also long ago gave up releasing supported versions for those older MacOS and OS X versions.

If you try out Momiji, or have a preferred alternative modern browser for older Macs and MacOS versions, share it with us in the comments!
