Sorry I thought it was intended to guide a possible K-Meleon user.
I hope my answer helps.
Yes, but siria's post is in answer to many peoples requests that clearly have cause in the down time of some Yahoo mail servers, forgotten passwords, ID thefts and simple ignorance.
BTW. Even You posted in answer to Subject
"can not enter my yahoo mail box"
My post is in answer to Subject
"I can not enter my yahoo mail box with K-Meleon"
This subtle difference is constantly causing Google and other search engines to direct people with generic but not K-Meleon specific problems here to the K-Meleon forums. And siria answered.
Yahoo Mail Box Use With K-Meleon Browser
1.) For the old yahoo mail You need K-Meleon 1.1-1.5.4 and spoof an older Firefox string.
See also: FAQs Why does website "X" not display/work properly? Is it a K-Meleon bug?
2.) For the "brand new Yahoo mail" You need K-Meleon 1.6.beta or newer and spoof e.g.
Mozilla/5.0 (Windows NT 5.1; rv:10.0a1) Gecko/20111008 Firefox/10.0a1
This string can be inserted into:
Menu item: Tools -> User Agent Custom
Or via Privacy Bar - Right Click on User Agent...
Else a modern User Agent String can be permanently added as an menu option via editing the file:
Approximately line 14, section // Privacy
Replace the original code with this. That adds the bold/highlighted UA string.
And two extra lines of code are inserted.
pref("kmeleon.privacy.useragent1.name", "Firefox 3.5");
pref("kmeleon.privacy.useragent1.string", "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:188.8.131.52) Gecko/20101130 Firefox/3.5.16");
pref("kmeleon.privacy.useragent2.name", "SeaMonkey 2.0");
pref("kmeleon.privacy.useragent2.string", "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:184.108.40.206) Gecko/20101123 SeaMonkey/2.0.11");
pref("kmeleon.privacy.useragent3.name", "Firefox 10");
pref("kmeleon.privacy.useragent3.string", "Mozilla/5.0 (Windows NT 5.1; rv:10.0a1) Gecko/20111008 Firefox/10.0a1");
