Unstable Rated 1 out of 5 stars

When installed this maxes out the FF application. It should be avoided at all costs until development has fixed.

Whoa!!! Super bad add! Slows FF to a crawl... causes FF to stop responding and startup is very slow.

Like the concept, but there must be a serious conflict other extensions or something like that.

makes ff3.5 almost unusable Rated 1 out of 5 stars

This add-on slows the loading of firefox to many minutes so as to make my computer unusable for long periods of time. Then clicking a web link in an email takes many minutes to load the page in ff. The author needs to look into what so people many are complaining about and mozilla needs to remove this add-on from the list of available add-ons until it is fixed.

Firefox 3.5 crashed immediately after installing this add-on and was unusable even after restarts.

Works Rated 5 out of 5 stars

Lot of alternatives to this add-on. But this one does what it should perfectly.

Rated 3 out of 5 stars

This extension caused frequent lock ups with Firefox 3.0.10. Less than 10 seconds into a new session, Firefox would lock up and have to be end tasked. Once this addon was disabled, the problem vanished.

If it would work without causing lock ups, it would be a very useful addon. When it does work, it's very useful. But crashing 4 times in 2 minutes is a bit much.

It works fine Rated 5 out of 5 stars

I have used this addon since Firefox 3.0 and do not see any problem. It is simple and allowes qiuck control of cookies.

STAY AWAY! Rated 1 out of 5 stars

**STAY AWAY!** It immediately locked up the Firefox browser. Thankfully I had the Google browser and was able to use it to find out how to start Firefox in safe mode without add-ons, allowing me to remove this thing. I'm not going to knock the maker because it may have worked fine with an earlier version of Firefox, but Firefox needs to remove this version of the add-on. Unless you want to roll the dice and hope that you are one of the fortunate few who has good luck with it I recommend that you stay completely away from it.

1-ClickWeather worked fine with all addons, until I installed this addon. What a shame.

The Extended Cookie Manager not only didn't work, it completely crashed my Firefox!

I had to restart Firefox several times before I could disable and uninstall this program.

Dieses Add-on sollte in experimentell verschoben werden, mein Firefox ist durch dieses Plugin abgestürzt und ich konnte ihn nur mit viel Mühe wieder aktivieren um das Plugin dann endlich zu deinstallieren.

This add-ons slow down and stops my firefox. After 3 minutes i received a message like "script chrome://xcm/content/xcmOverlay.js:196 blocked".
The only solution was to remove it.
(BTW I have a dell with a core duo T8800 with 4GB of ram)

I love this add-on. Rated 5 out of 5 stars

My computer has no problem handling this add-on. I simply cannot imagine living without it or without having something similar in my life.
