terrible

Works great on Firefox Quantum 60.0.2

Me gusta porque responde a casi todo tipo de preguntas,sean matematicas o no!

Great extension. I LOVE being able to search the worlds largest computational knowledge database at the tips of my fingers/

If you are on internet and you are on purpose then this is the search engine you need.

If this keep up being as good of a search engine as I use it for, this is the next google!!! Maybe even better!

This is a must-have for daily internet users. Superb work by great people with whom I have had the privilege of working with during the NKS Summer School of 2009.

Wow, das ist nicht nur eine Suchmaschine das ist ein richtiges Werkzeug. Es lassen sich Graphen von Funktionen darstellen(Bsp.: plot x^2), Funktionen lösen (auch elktrotechnische und physikalische), integrieren, differenzieren, fast alles dabei. Die Ergebnisse lassen sich dann sogar als PDF speichern.
Genial! Leider bisher nur in englisch.

Beats Google on many searches. Comparison searches with 'vs.' are awesome - its like doing instant information visualization of data with just a text search. Amazing natural language queries. I totally love it !!!

This has just got to be the greatest search engine if your mostly interested in raw facts but also like to have access to more elaborate information. Nice to have the add-on in Firefox. Works perfectly fine with me using version 3.0.10.

It is the most complete search engine because it allows the user a direct access to whatever he is looking for and also showing other relevant info.Although it is still experimental I say it is better than Google or any other search engine. 7 stars!

Wolfram Alpha search is amazing. I find it extremely helpful, and I am glad that the Firefox extension is already here. WAlpha is useful if you want to know, for example, the distance between New York and Cincinnati, without having to type the question into Google. I find it very efficient, and having the Firefox extension makes it even more effective.
