DebugBar, Companion.JS And IETester

Some days ago a colleague of mine pointed out to me this tool (IETester) that allows testing the different rendering and JavaScript engines of Internet Explorer (5.5, 6, 7 and 8beta1) side by side with the installed version.

I haven’t tested IETester yet, but I found two other tools in the site that caught my attention: DebugBar and Companion.JS.

DebugBar is like other tools I use [^] with a few differences. DebugBar is an explorer bar (and docks on the left side of IE) and can’t be undocked but has a JavaScript console and tracks only the HTTP/HTTPS traffic that belongs to the visible web browser tab (IE 7). DebugBar can also spy on other instances of IE like Document Explorer or FeedDemon.

Companion.JS is a Firebug-like tool and was the one that liked the most because it gave me something that I hadn’t: something that kills those annoying scripting error dialogs.

Both DebugBar and Companion.JS claim to be JavaScript debuggers but I couldn’t find any way for setting breakpoints or running scripts step by step. Probably because I have Visual Studio installed on this machine.
