Useless Now in FF13 Rated 1 out of 5 stars
"Add-ons are compatible by default in Firefox 10+. As a result, the ACR's functionality has changed, and it can no longer be used to force add-ons to be installed."
Translation: This add-on now has literally no purpose. Uninstalled. FF13 tried to tell me that Digger, Copy Plain Text, and Screengrab are no longer compatible with FF13. Usually I'd simply use Add-on Compatibility Reporter to force-enable these types of add-ons, and usually they'd work just fine. Why does Firefox think they're incompatible? Oh, because an add-on's install.rdf file claims that the max version is version x, which is less than the current version. The solution? Change the max version to anything higher than the current version (I just set it to 100.0), and guess what? Firefox goes, "Oh, duhhhh, green light!" And wouldn't you know it - all three of the add-ons I mentioned above work flawlessly in FF13 after this modification. This just goes to show how asinine FF's method of checking compatibility actually is, and further, how asinine it is that they can no longer be force-enabled. This browser is taking a turn for the idiotic.
