Strange bug when browsing forum pages

[Sayd]

I recently notices strange bug: sometimes when browsing forum
pages I can't go back to previuos page (I used backspace and
directly hit the "Back" button, no reaction). Only after 2 or 3 hits browser
show me previous page. I turned off javascript and bug
disappeared. Also I noticed withing "Back history" there are 2 strange records:

I'm using latest Opera 11.62 (Win7).

Do you get the same issue with different browsers? I use Chrome and have never seen this (nor with FF, that I used to use).

Have you linked your forum account to Facebook?

Have you linked your forum account to Facebook?

No, I didn't becouse I don't have any facebook account.

I asked because the extraneous history entry mentions facebook.
Test and make sure this does not work the same way with any other sites, could be you have a virus or spybot of some kind, no one else has reported it here.

I have outdated IE8 with the same problems - inside history I can see jscript code and url to facebook js code.

I didn't see same entries for other sites. I have Kaspesky 2012 running, it didn't detect any problems. I turned it off to check -- no difference.
Right now I have that problem only with your forum and site.

Cleared the browser cache and cookies?

Cleared the browser cache and cookies?

Of course - no, I have 20Mb on disk for cache, it clears automatically.
I did exit from forum, checked if cookie exists (no cookie), logged in again -- no difference.

I've found limited solution: Opera can be configured to block connections to specified pages or just everything. I traced your site with internal dev tool from Opera to see which js code is loaded and saw a load from https://connect.facebook.net/. I tryed to block this site, after that I don't see any JS code inside history. So one part of my problem was JS code from facebook, so I suppose you should probably debug it better.

It is standard vbulletin, not really something we can change.

 

[Sayd]

Exact script location is https://connect.facebook.net/en_US/all.js

vbulletin seems to work, I can post here via quick reply, etc, JS seems to work with other parts of forum.

I noticed this behaviour week or more ago. Probably facebook changed something, but I don't know any other site with vbulletin + facebook connections to test them.

 

[AndrewT]

Probably facebook changed something

Possibly, but as noted above only you are having this problem, as far as we know.

You said above you had no cookies for this site. That would be very unusual unless you are deliberately blocking them - are you?

 

[Sayd]

No, I don't block them. May be I missed them. I got same issue with my netbook's IE9 Win7.
I think we can finish now, I've found solution for me, everyone else will wait for fixes if they ever have this problem.
Thanks for your patience.

It may be an option in vbulletin, however, I don't see it in any of the other vbulletin boards I follow. This is quite troubling because we don't know what may actually be loaded with those pages (especially those of us who avoid Facebook out of concerns about their security and privacy issues).

I only see this after I use the back button to leave a page.
