Social networks and browser differences.

[kgun]

I have noted some differences on social network sites:

1. FaceBook
   
   IE. 6.0: Sorry, the new facebook is temporarily disabled. Chat unavailable.
   
   FireFox: Welcome to, the new facebook. Chat available.
   
   Opera:Welcome to, the new facebook. Chat unavailable.
2. LinkedIn
   
   This site Meta Search Engine and search resources: SurfToolbar.com is different on Opera and the other two browsers. Look at the Linked in message in the lower left corner. My comapany is registered in the LinkedIn database.
   
   Opera:
   
   0 people on LinkedIn work at (Code pasted from the page)
   
   MultiFinansIT
   See how you’re connected
   Access them in minutes
   
   Register or sign in »
   
   About LinkedIn »
   
   IE and FireFox:
   
   1 connection works at (Code pasted from the page)
   MultiFinansIT
   
   Kjell Bleivik
   
   
   See this connection »
   
   
3. When logging out from WPW, Opera ask:
   
   Stop executing scripts on this page? No such question on IE and FF.
4. Now my question is. Is this related to security issues, (default) browser configuration or other differences?

Any opinions?

Note: I use default settings in Opera (9.51) and FF (2.0.0.16)

[kgun]

Give and take. I was surprised that this thread was puplished on the home page of WPW. Some of you that use my sites know that there are overlap of linkcollections for semantic reasons. I am working on the Peer to peer site of MultiFinanceIT (second signature link). I renamed the site to

P2P: Peer to peer and social networks.

Now the related linkcollection that may be of interest to some members and visitors (the surfer is still the boss) are semantically linked in in the upper right corner of

Cybertoolbar.com: A collection of popular resources related to the cyberspace.

with the anchor text: P2P-Links.

The links are there for you to use.

With the recent revamp of Face Book, I'd expect some aberrations until it's truly ready for prime time.

As regards Opera, and with no personal usage experience to go on other than with IE & FF, I'd hazard a quess that the answer there lies in its own settings and/or its interaction with the OS.

I recently heard that Internet explorer 6.0 is only compatible with the old Facebook layout.

1. That Opera is different may be due to the default browser settings, but I am not sure.
2. Did you note the difference that happened when I copied and pasted the same code from the "Opera and IE /FF" page? That is an interesting difference.
3. I know that Opera is nearly paranoid on security. Their overall security principle is:
   
   "Don't rely on any internet site."
   
   That is why I recommend Opera for the surfer. My children constantly got viruses. After installing Opera, they have not had a single known infection. I think we are too sloppy on security issues.
   
   Regarding toolbars and plugins. There are hundreds if not thousands of them for FireFox. I would be very careful with directly recomending such plugins / toolbars, even if I have links to some I personally regard as secure in my link collection. But who knows?
   
   So back to the LinkedIn plugin. It functions with default settings in IE and FF but not in Opera. Look at the source of the LinkedIn olugin:
   

    
   The company that owns this site has one account on:<br /><br /> 
      <span id="mfit"></span>  
         <script type="text/javascript">           
          new LinkedIn.CompanyInsiderBox("mfit","MultiFinansIT");     
      </script>

   From the Opera security and privacy page.

"JavaScript

JavaScript (or actually ECMAScript) is a means of embedding executable content in Web pages. It is used for everything from making image links change when your mouse hovers over them, to receiving and sending cookies.

These scripts are completely safe most of the time, but they have been used for malicious purposes. JavaScript should not be able to access applications and information outside the Web page it resides on, but if you still fear JavaScript abuse, you can choose to disable it. You can also put some limits on what Opera should let the script do, e.g., resize or move windows, by clicking "JavaScript options". And you can choose to have the JavaScript console displayed should there be an error.
If you completely disable JavaScript, however, some sites may report errors, fail to display vital content such as menus or even shut you out. Remember that JavaScript is easily toggled on and off by way of Opera's "Quick preferences", that is displayed by pressing F12".

My bolding. That is (most probably) the reason since I have JavaScript enabled. It is regarded as a fact that cross server scripting is impossible in Opera. This may be an indication that that is true. I agree with Opera on this issue.

Aside from facts, this was no Ad for Opera. As a webmaster, I find FireFox and FireBug very useful, but will never recommend another browser than Opera for the uninformed surfer in 2008. Now I recommend my children to use OpenID. May be it takes additional 4 years before they use it (it can be misused, but is more secure than the alternative - no digital Id).

Does it also has some "noscript" default code that accounts for the results you observed and pasted into your 1st post?

[kgun]

Hitting F12 in Opera, the following



options are active:

• Open all pop ups.
• Enable animated pages.
• Enable Java
• Enable Plugins
• Enable Javascript.
• Enable cookies.

The following is unchecked:

• Enable sound in web pages.
• Send referrer information.
• Enable proxy servers.

Under advanced preferences

• Enable fraud protection is checked.
• Networks: Max connection to server is 8 (default).

There are so many choices under advanced settings that an Opera specialist should answer. I am a beginner.

P.S. Writing this answer, I noted new features:
"Adding new searches

Opera comes with a useful set of default search engines, but you may want to add some of your own favorite searches to the mix.

Adding a new search is most conveniently done as follows: (My addition: CTRL + F12 gives you an overview)

1. Go to the site that has the search you want.
2. Right-click the search field.
3. Select "Create search" from the context menu.
4. Edit the name of the search engine to your liking.
5. Add a short keyword to be able to use the search engine directly from the address field, as described above.
6. Click "OK", and the new search is added and can be used anywhere within Opera.

If you want to make the new search your default search engine, expand the dialog by clicking the "Details" button, and check the "Use as default search engine" box. You can also make it your default search engine for Speed Dial by checking the "Use as Speed Dial search engine" box.
In the expanded dialog, you can also edit the search string directly and specify that the POST method should be used for this search".

The oddity that you note is not confined to Opera. I've just now observed the same behavior on IE 6. And, whether related or purely coincidental, the following Scripting Error is observed:

Line: 14
Char: 1
Error: Object expected
Code: 0
URL: Meta Search Engine and search resources: SurfToolbar.com

Code in the head of the page:

<script src="http://www.linkedin.com/companyInsider?script&useBorder=no" type="text/javascript"></script>

Does it ...?

Do you mean the browser setting or my page?

Now I note the following:

On advanced + content + JavaScript options. (I can't see that any of those default options are the reason).

[deepsand]

I was referring to the presence or absence of the HTML <noscript> tag in the page itself; HTML NOSCRIPT TAG

Definition and Usage
The noscript element is used to define an alternate content (text) if a script is NOT executed.
This tag is used for browsers that recognizes the <script> tag, but does not support the script in it.

OK something like and Image with an alt attribute. Good hint.

But I think that the reason that the information about my company is different in Opera and FF / IE is that cross server scripting is not possible in Opera as far as I know.

Can't cross server scripting be used to steal a credit card number?

That might not be the actual line referred to. I may be wrong, but I believe that the error reporter does not include Comment lines in its line count.

As noted above, I am seeing, in IE 6, precisely the same results as you've observed using Opera.

[kgun]

Opera: 0 people on LinkedIn work at

FF and IE 6.0.2900.2180: 1 connection on LinkedIn works at

It is eviden that no content is deliverd from the Linked In database to the Opera page.

[deepsand]

Understood, but, what I see under IE 6 is

0 people on LinkedIn work at

MultiFinansIT

• See how you’re connected
• Access them in minutes

[kgun]

Wait, I am logging in on Opera.

1 connection works at

Time to log out?

[deepsand]

Precisely. That is why I said that this appears to not be an issue with Opera itself.

[kgun]

Did you note my edited post?

[deepsand]

Same result, i.e.

0 people on LinkedIn work at
MultiFinansIT

• See how you’re connected
• Access them in minutes

but without Script Error.

[kgun]

So if you had logged into LinkedIn you would have seen...

Most professional social network site?

As I do not have an account with LinkedIn, I cannot say.

[kgun]

And I may have misunderstood the concept of Cross site scripting ?


There are two logout states on the site:

1. Log out.
2. Complete logout.

I only use 1 and have never logged in on Opera. Took a time before I understood the difference.

Cool functionality.

Cool if one has the owner's manual!

If I had to choose, I would prefer the owners manual to the Google infra structure. Most probably I had to hire 10 mathematicians via the Linked In network to crack the code.

With that tool / plugin I may find them when surfing web sites that I like.

Can you guess where I first heard about LinkedIn?

I answer for you. Ukraine.

I think this SE is www.com &mdash; the web starts here Ukrainian. What a name.

[deepsand]

So, is it then the case that what Linked In reports is dependent on whether or not you are logged in and/or which browser you used to log in?

BTW, I'd hesitate to say "Idiotic Norwegian." One cannot be expected to understand that which is not yet known. And, thanks for the rep. points.

Considering that Google remains a work in progress, it's doubtful that even they have a complete, accurate & timely manual!

Poignantly, the Registrar is "MONIKER ONLINE SERVICES, INC."

While the Registrant's address is in Canada, the name, "Yonatan, Belousov domains@original.com," suggests Byelorussian.

1. You have to be logged in (not completely logged out) to be identified.
2. That should indicate that the browser is identified by the application.
3. I am not identified unless I clear browser settings, that means log out completely (see below).

As I told above. If you sign out, you get a new message on a button that says:

Sign out completely.

"When you click this button, this browser will not remember any information about you, and you will have to enter both email address and password to use the system".

Very few sites have a "destructor" option or a "garbage collector". That gives a professional impression IMO.

Yes, I felt like an idiot when I understood the difference. I thought:

How many posts do you have to write before I understand the application?

Whome are that. I don't use the SE, but the name should have potential or do you disagree on that? I noted the bot when it visited my forum.

How many searches include WWW or is it filtered out?

Update on Cross site scripting here: XSS: Cross site scripting. An update.

For Facebook, I use SeaMonkey which is a Mozilla derivative. I complained when I got the message about chat not working and that I should use FireFox and lo and behold a few days later it worked!
