Rated 5 out of 5 stars
Firefox has a pesky annoyance: the lack of "partial name matching" mechanism in the cookies list. Oddly enough, the "Saved Passwords" list does have the mechanism . . . making the cookies list more irritating . . . lol.
The CookieExFilter add-on solves the problem with flying colors. I enterd "ens" and it selected the 2 matching items from my list of dozens: "opensuse" and "licensing". I refined to "ensi", and selection was narrowed to 1: "licensing". Powerful matching mechanism, and easy as pie to use.
Further, it solves a number of other inconveniences---this add-on does its job very well.
Only difficulty I found is that I couldn't figure out what the preferences "Add Search Bar" to "Popups", and to "Images" meant. Which popups? Which images?
Deserves 5 stars.
