Thanks for taking the time to report this!

Please describe what "don't work" means, and provide steps to reproduce on gl.wikipedia.org (I have no idea how to use HotCat and reproduce the problem, and I assume that "enhanced editing toolbar" is the stuff at the bottom, like "Formato wiki:"?)

Does "don't work" mean that clicking an item in "Formato wiki:" jumps to the top? If so, see bug 56718 for how to fix this.

As a first good step when trying to track down problems, could you please open the Error Console (or whatever it is called in your browser) and reload the page that you see the problem on? If there is a problem or an error with JavaScript it should be printed in that console.
For more information please see:

• Internet Explorer: http://msdn.microsoft.com/en-us/library/ie/dn255006

More info: I consulted some articles in en.wiki and es.wiki and the two tools worked fine with my user in that wikis. The same in ca.wiki, eu.wiki, fi.wiki...

Being logged in, I do see the advanced editing toolbar on https://gl.wikipedia.org/w/index.php?title=Lingua_galega&action=edit shown in https://commons.wikimedia.org/wiki/File:Add-media-wizard-button-screen-shot.png in Firefox 25.

Could you provide links to compare?

HotCat seems to be https://gl.wikipedia.org/wiki/MediaWiki:Gadget-HotCat.js ?

I have Firefox 25 too and I can't view the advanced toolbar in that edit and I have checked the Hot Cat preference., I don't understand why it doesn't work in my computer.

Yes, HotCat is in that url, but, I don't know why it doesn't work.

I have found the problem, but not the solution. If I unmatch "Disambiguation detector" at preferences-Gadgets-Browsing, then the advanced edit toolbar and the HotCat work!

But I don't know how to fix the problem.

I think that I solved the problem updating the code of https://gl.wikipedia.org/wiki/MediaWiki:Gadget-DetectorHomonimos.js.

I will do some tests and then I'll report it.

It's fixed, thanks for your help!

Happy to hear that it works for you again. Closing as INVALID as this was not a bug in MediaWiki software or its extension, but in an on-wiki script.
