I love this plugin, but isn't working with FF8.0.1 and Growl 1.3.2 Rated 5 out of 5 stars
This was my go-to plugin for development, but it stopped working recently. It doesn't seem to either empty the cache or reload the page. :( (Mac OS X Lion)
UPDATE: Yes, this appears to be a FF bug. Hopefully it will be fixed soon.
It's probably a Firefox bug
Sorry to hear that but I think it's a Firefox (Mac version) bug ... the cache clearing API didn't change and it works fine on other platforms.
Can you try another cache clearing extension and report back if it works? Thanks.
