The first K-meleon that I used was 1.5.4, alternating with Crazy Browser. Sometimes it gives me problems, but I can not use another. There were a couple of years where I was worried because the 1.6.x seemed to be obsolete. I tried Palemoon, Qt, Firefox, Iron, Avantbrowser and some more. They go well, all right, but there's no way I'm comfortable. Either I find them heavy or a joke; for example, Qt, you only have to establish three or four things, K-meleon, instead, you have to work a little, but then you feel at home. You can not recommend it to anyone, because if you do not configure it as you wish, you can use any other. Time passes and remains the fastest. So I'm very happy with 75 and 76. It's the Foobar of the network!
I use it both in Windows and in Linux. I regret not being able to help and I thank everyone very much for their time and work (by the way, I can not get the Rss-atom subscription to work; it would also find interesting an add-on for feedly, freshrss or other similar services). Regards
