There is no good way to inform slave elinks instances about options. So, for mouse there is a workaround.
Note, If you set ui.mouse_disable = 1 in elinks.conf manually, to get effect on 2nd ELinks instance,
you must also touch ~/.elinks/mouse.lock . Changes via option manager delete or create this file automatically.
SpiderMonkey was updated to mozjs24. If you want to build elinks
with ecmascript support, you must compile using g++ with -fpermissive .
There is a lot of warnings.
There are some memleaks in ecmascript code, especially related to JSAutoCompartment.
I don't know yet, where and how to free it.
Debian does not support mozjs24, so I'm going to gradually update SpiderMonkey version.
