StumbleUpon Logging Me Out?

After using "StumbleUpon", I'm finding that I have to login to my usual websites again, eventhough I had visited them shortly before using StumbleUpon. Is it possible that StumbleUpon is logging me out of the websites? This isn't the first time, that it's happened, and I haven't done anything else on the computer except surf and e-mail.
:confused

 

try cleaning out your internet temp/history and cookies because the site maybe don't like/clashing with somthing in your temp folders also u could try resetting your web settings

 

Thanks!
1. If I clean out my internet temp/history and cookies, would I just end up having to login again, just as I'm doing now?
2. How would I go about resetting my web settings?
:confused

 

yes you would still have to log on but you would know that the web page an't clashing with anything

tools /internet options then advance tab then reset web browser.

its just call prosses of elemination

also have you tryed to log into the site from a different pc?

 

I'm so sorry, I failed to mention that I'm using FireFox.

This is the program StumbleUpon that I was speaking of;
https://addons.mozilla.org/en-US/fi...tion=firefox&category=Popular&numpg=10&id=138

No, I haven't tried logging onto the sites from a different PC.

I wonder if perhaps if I view several webpages with the StumbleUpon Extension, that my FireFox browser is just overwhelmed and is cleaning up? lol

 

So, I used the FireFox Extension "StumbleUpon" last night, then this morning when I turned the computer on, I had to log on to all my usual websites again. I didn't do anything different with the computer except use that extension. Is there a setting I can change and exactly how do I go about doing it?
Thanks!

 

Thank you, I'll try this.

 

Just to update;

Unfortunatly, with several trials, I'm still having the same problem.
(When using FireFox "StumbleUpon" for a period of time, when I go to click on my usual forums, I'm logged out of all of them.)

 

I'm addicted to the program, so I'll just deal with it, lol. Thanks for your previous suggestions, much appreciated!

 

Eureka!

Ok, so far, I think I may have found the trick. (Using FireFox browser). I open one window with several tabs with my favourite forums logged on.

I open a second window and use the "StumbleUpon" program within that.

After Stumbling for a while, I'll go back to the first window, hit refresh in each tab to update posts within the logged on websites, and so far so good I'm still logged into my favourite sites.

Conclusion
Have your favourite logged on websites open in one window with tabs, and use StumbleUpon within another window.
