    I am looking for a freelancer to customize a web browser for me. The task is to fix the lack of JS support in our custom web browser... without breaking anything else.

It is JavaScript support that needs to be updated. Our own web browser does not provide dev tools, error console or view-page-source, so it will be useless for debugging. However we can provide the source for the browser that we forked from which will be identical in all relevant aspects. We will provide the original source that we used for our browser, with build instructions and a ready compiled binary for initial testing. Previous...
