StumbleUpon Rated 2 out of 5 stars

StumbleUpon takes over the hotkey Ctrl+Shift+N which is incognito mode for firefox. There is no option to change this, which is awful.

The websites aren't terribly random (if you look at other stumblers likes you'll see that the vast majority of websites are seen by everyone, so its more like an app that automatically sends you to trending websites)

A tool that helped me a lot in latest years, to promote and to build a strong community on my website. Besides that, SU has always helped me find new and innovative content online.

very nice Rated 5 out of 5 stars

StumbleUpon is my most favorite website. I love its features. It's easy and fun to use. I love how it shows a thumbnail of your favorite websites on your personal page.

Thunderball must not know how to use this!

It's nice to "Stumble" from time to time just to broaden your interests.

Worthwhile.

Rated 1 out of 5 stars

Totally useless for finding INFORMATION on subjects of interest. It is only a SPAM add-on that only shows search results of high priced useless junk for SALE.So after trying to find if there was any hidden settings that blocked any useful INFORMATION, and finding none, I uninstalled it . Junk/SPAM add-on. Should be removed from the Mozilla add-on site.

Cool! Rated 5 out of 5 stars

I discover articles that I would never find on my own.

It won't log in. Rated 1 out of 5 stars

StumbleUpon will be no fun till this is fixed :(

It won't log in. Rated 1 out of 5 stars

Trust me it wont. I've followed all the standared instructions, reset my password, even reinstalled the thing. It knows I'm logged into the site, but the bar just won't log me in. (I've had this problem on both windows and linux.) Though, yes the idea is like perfect.

StumbleUpon would not be the same without the add-on. The add-on practically makes the site.
