i remember using this first before actively joining the site itself

..i also remember that when i uninstalled it because the site offered the same things anyway;what i'd liked when 'stumbling'...all gone.

apparently it was saved into a bookmark folder and once i got rid of that too,.. it wasn't 'backed up' in my actual account so no way of ever recovering it.

aside from that, it actually worked exactly the way it says and i had no problems-wouldn't ever know i had any - if i hadn't decided randomly that it was one of those types that i didn't really need.

of course, i don't intend to ever reinstall it again (misc. reason mentioned above) but since others most probably would..i'd recommend looking into that.

thank you for reading and sorry to bother you.

A SYSTEM CRASH WAITING TO HAPPEN! Rated 1 out of 5 stars

The software itself is OK.
The problem is that you visit so many sites that you are bound to wind up with a virus, a worm, mallware, etc.

I thought it was great, too. That is until I had two system crashes in six weeks.

USE AT YOUR OWN RISK!

SU recently released a new version (V4) which is poorly developed and vastly inferior to previous version.

Pros: None. Compared to the old version which rightly deserves high marks, this version has no redeeming features.

Cons: Ability to add friends with common interests has been removed. Visual editing of your pages has been removed. Visitor counter is inaccurate. Customization of pages has been limited to only a few basic tweaks. Overall feel is less intuitive.

Summary: The company says the new version (V4) is more social and user friendly but the exact opposite is true.

Cannot change the default password - says "ERROR_UNKNOWN_ERROR". Tried restarting firefox - doesn't help. Really dissapointed as I will not remember the generated password and do not like storing passwords in browser.

Stumbleupon is the Best! Rated 5 out of 5 stars

When I first joined I used it a little but after about a week or so the number of favorites I had skyrocketed! I have used stumbleupon for anything from researching for a school project to finding a fun recipe or just for fun!

Great new update 3.52, everything works fine but just wanted to let mozilla know that the link must be broken here because i get the unable to download -228 error. Looked into it and I just downloaded from StumbleUpon's actual site and it worked perfect.

Great app, but there appears to be a bug in the latest version. Whenever I stumble, I always get the same page until I change the category. For example, I have it on all, and every time I press stumble, it'll just reload the same page. Then I change it to humour, and it'll load a different page, but if I press stumble again, it'll just reload this new page. So I have to change it back to all, and the whole cycle starts again.

I love this add-on, as much for the easy stumbling but for the ability to email sites to people (it keeps a menu of all the email addresses I've sent to). It also is great for driving traffic to my site.

Makes adding favorites to StumpleUpon very simple by clicking "I like it!". I chose this add-on last week on my desktop and have doubled my favorites thanks to this add-on. I would like to give it 10 stars!

I love it, and have used it off and on for a few years now. Only problem I have is that I have A.D.D., and StumbleUpon gets me side-tracked a lot. lol
But seriously, I would recommend it to anyone. It's a great time-waster, a great tool for work, and it's great fun if you're just REALLY bored online and just wanna "surf the 'net".
