For lost capo Rated 1 out of 5 stars
UPDATE: Doesn't work in 3.0.1 :-( Someone has a solution?
Took me a few minutes but now I get it!:-) You have to install 0.3.7 version provided by sperenz55 and then go to about:config, into filter put url and at the bottom of the page are all the suffixes you can change - without the extension installed they're not there. Originally I thought sperenz55 wrote two alternative ways but it's all one manual ;-)
