Today I used a new technique for downloading some rigs from RE, which involves DownThemAll and Nuke Anything Enhanced, two powerful free plug-ins for Firefox.
Let's say you want to download r_u_serious last set of profiles related to his Marshall. This is just an example, in some cases you have enough elements to isolate just the files you need, but in case there's ambiguity and you are responded with a larger selection of rigs than your search target you can proceed as follow:
search for r_u. You're returned with a number of files, the first n of which are the 1970 Marshall. Select with a single elegant mouse gesture (LOL) all the contiguous files in the page you're not interested in, right-click and choose "eliminate selection" (or whatever the English version reads). Then right-click again on an empty area in the page and select DowThemAll or DownOneClick. Done.
Note: this implies that you've already defined a "*.kipr" mask in DDA, but it's a DIOAF operation
Let me know if it works for you!
PS: Nuke Anything is a powerful too per se, it can be useful in a number of very diverse circumstances.
For example, I use it when I want to save a page full of stuff I don't need (ads, banners, headers, pictures, blablablas)
