there are no problems here with tgdaily..i was able to access almost all links(cool site by the way) with out problems or any script errors..the site for the most part is well-coded too, producing few errors in the console and only one that was particularly critical Error:
'Permission denied to get property HTMLDocument.body' when calling method: [nsIDOMEventListener::handleEvent] = NS_ERROR_XPC_JS_THREW_STRINGbut
not enough to produce a crash or a script, k-meleon is just blocking a domevent it's regarding as a security thing
i didn't change my useragent maybe that's your problem? using an agent that made the site inject special js code not for 1.8..try browsing with the default agen, you don't need to use the ff agent with that site.
naturally there are js codes that are specific to 1.9+ gecko but so far i havent run into one that cripples k-meleon or completely blocks the site.. some features may not work requiring tracemonkey etc but it shouldn't cause a script error or a crash..anywho, the devs are aware of the limitations of the current 1.8 engine and are working on an update to 1.6 but you see.. unlike other browsers that rush and adopt new engines without enough testing etc the devs for k-meleon (within their very limited time) cannot migrate to a new engine unless everything has been tested enough to work seamlessly and without problems.
sure they can easily throw in the new engine in a couple of days, and trust me it's not that hard..as various unofficial releases include the new gecko but that will produce endless problems, bug reports and bitching users will come in with all sorts of complaints.. we all know the problems firefox has went through when they hastily used 1.9.1+...numerous bugs and patches and updates released every couple of weeks. if you notice , the seamonkey devs have been cautious taking in 1.9.. they have been testing it for almost 2 years and until very recently(a month ago) their official version was using gecko 1.8.. they are good guys just like the km ones, they take their time to ensure no loose ends in their final product.
if you just can't wait..then i highly recommend that you try the unoficial kmeleons like fred's nx/sm editions or hao's ccfme, both using the latest gecko trunk
