Great module, however, for some time, it has been slowing down some websites. For example, youtube can take up to 20s to load (on a powerful mac).

it slowing down firefox. youtube opens after 10+ seconds... I Disabled it until it will be fixed.

It's slowing down Firefox since the last update, had to disable it for now..

This extension is great, but is slowing down Firefox significantly after its update. YouTube has gone from instant loading to 10secs+, Reddit, Google, Facebook, etc. All take 2-3secs+ now. Drove me crazy until I disabled every plugin I had and started enabling them one-by-one.

Great plugin. Unfortunately on the latest firefox version in ubuntu, the add on is incredibly slowing down firefox.

I like the extension a lot. Seeing how there are other extensions that do the same but give different results, some better indication of how the results were obtained and how dependable they are wouid be great.
One bug I encountered: The Export function fails (download gets in FF download list but just fails)

This is such a handy tool whenever you are curious about the technologies used on a website. Whenever I find a website interesting, I can easily peek at what technologies they used and it also greatly helps while developing my own websites.

It's amazing

Best extension to detect technologies but it's quite heavy in performance and sometimes a bit buggy.

It does not work most of the time. Use BuiltWith instead.
