Earlier we have posted two articles about the memory usage of browsers and also some alternative light weight browsers. which you can read here Memory usage of the browsers - Lightest browser and 3 Alternate Browsers - Lightweight browsers.
K-Meleon is an open source browser which uses the Gecko engine developed by Mozilla.
K-Meleon is one of the lightest browser in the list, but they stopped the development on 2012 (Last release was on 12/12/2012). After a year they started the development again and released the first beta on 16th January 2014. Now on 8th August they have released the first release candidate after 3 Beta releases. The application do not have a 64 bit version.
You can read more and get the K-Meleon 74 Beta 4/ RC from here. Remember the latest version is in Release candidate stage which may have bugs and may not even work as expected. So if you were a K-Meleon user earlier we would like to hear from you about the new development. Leave a comment.
