Show HN: Fresh Fresh extension for Firefox

Hi everyone, a few weeks back I released an extension for Chrome that faded out old content automatically as you browsed certain sites (HN, Reddit, YouTube, news sites). It was pretty well received, so I've translated it to Firefox: https://addons.mozilla.org/en-US/firefox/addon/fresh-fresh/ https://addons.mozilla.org/en-US/firefox/addon/fresh-fresh/ Hope you find it useful and would love to hear what you think. The original Chrome version is also still available: https://chrome.google.com/webstore/detail/fresh-fresh/ileahjmkefakkiimcocmnoppbnkpehfp https://chrome.google.com/webstore/detail/fresh-fresh/ileahj...
