Two new "CacheViewer" add-ons Rated 4 out of 5 stars
There are two other ("experimental") "CacheViewer" add-ons, based on the old one, available on this site: "CacheViewer Continued" and "CacheViewer Fx6". Type CacheViewer in the search box on this page. Haven't checked those as the old one still works for me on my FF6.0 as I mentioned below. Good luck!This review is for a previous version of the add-on (0.6.3).
If the "Preview" doesn't work... Rated 4 out of 5 stars
If the PREVIEW doesn't work (even after you've edited the install.rdf), you have to go to the bottom of this page, click on "Version Information", then on "View all versions" and get the LATEST version of CacheViewer (0.7b right now). The version on the main page is only 0.6.3 right now. Even in the latest version 0.7b you will have to edit manually the install.rdf file in the known manner.This review is for a previous version of the add-on (0.6.3).
