I do remember Venkman crashing multiple times, but to be fair it was the older "sort of stand-alone"-ish Venkman. The later version packed as an extension was a bit more stable. But going back to the relevance subject, I don't really think it is worth mentioning. But not because of performance but because it was a fairly different thing. Mostly just a JS debugger with a couple of additional tools and little/no support. Usually you would need a bunch of other scripts such as XRAY [0] and others to reach a functionality somewhat comparable to Firebug. [0] https://westciv.com/xray/ https://westciv.com/xray/
