Thanks, it works! Rated 5 out of 5 stars
Many setttings have been removed or dumbed down. This add-on helps to return these settings to the Preferences panel. There are still more settings that could be exposed, though I cannot specifically recall them.
SeaMonkey has traditionally had more settings available outside of about:config. Unfortunately, there is not a regular 64-bit build of SeaMonkey available for Linux. I wish they never separated the code. It would be great to have the installation similar to the way Netscape was, where one could install the entire suite or just individual components. The code for the browser was the same whether one installed the suite or just the browser. This really is just my rant, I don't expect the author to resolve these additional issues. Additional preferences would be nice though.
