Bookmarks don't work from 1.1.6
Had to re-load 1.1.6

Make sure that You set Preferences Bookmarks to know here the bookmarks file of Your choice is or copy the bookmarks.html that You want to reuse into Your new 1.5 profile.

I have several K-Meleon installed in working condition & I use the very same bookmarks.html file for all official M-Meleon 1.1.4 de-DE to 1.5.0 de-DE plus in several test versions. They all use this file that is in an 1.1.4 profile - but the file is much older (You can still use a K-Meleon 0.8 or older bookmarks file).
