How Can I filter out (hide) a Chrome extension

[Frederik]

Hello,

I am new with Fiddler.  Please bear with my inexperience. :-)

My result panel is polluted with a Chrome extension 500 error. The URL is http://127.0.0.1:55296/ChromeExt/pabeoippfoppjkpbmbpjjjglbldlajfg.  Please find a screenshot attached.

 

Could you please tell me what my filter options would be?

I have tried:

* Filter rule: Request header > Hide if URL contains: "/ChromeExt/pabeoippfoppjkpbmbpjjjglbldlajfg"

* Script rule:

if ( oSession.url.Contains("/ChromeExt/pabeoippfoppjkpbmbpjjjglbldlajfg") ) 
        {   
            oSession["ui-hide"] = "yup"; // "The "yup" value is unimportant"
        }

 

What am I missing?

 

Thanks in advance for your help

Hi Frederik,

Please, pardon us for the delay in our answer.

Is the value in the "Hide if URL contains" filter rule with the quotes or without them? In which method did you put the script rule?

This post is indeed good, so far so good.

I'm having same issue.  I used essentially the same code in the OnBeforeResponse method.  I can't seem to get rid of '/ChromeExt/pabeoippfoppjkpbmbpjjjglbldlajfg'.

If i right click on the result panel and click 'filter now' and '/chromeext/' ... it filters from the result panel and then new ones start coming in.

Hi Frank,

Would it be possible that you share the name of the extension? I would like to try to reproduce the problem you have.

After additional research, it appears to be an extension that is not from the web store but from employer. 

You can close my inquiry.  Thank you for your time.

There's a way of filtering out all these requests. In the network tab filter box, use the string "-Scheme:chrome-extension" (quotes for clarity). It would be a good thing to be able to activate this filter (or other filters) by default (as part of the configuration settings). Note that this filter will not filter the /https requests made by an if any. The real solution is for the network waterfall to have channels for the page and each of the extensions.

I can't seem to locate the network tab in Fiddler.  

I've already tried the filter tab and added 'Hide if URL contains' /ChromeExt and that did not work.  I've also attempted to filter thru script rules.  Both of these options are discussed in the original post from Frederik.

Still, everyone faces this issue? No one can find the solution or what actual problem?

Think I figure it out.  Nothing I tried, script-wise, would filter or change them - not even changing the "ui-color".  So I started looking at the log window and found it showing:

 

14:47:55:1667 Fiddler.Network.ProtocolViolation - [#184] The Server did not return properly formatted HTTP Headers. HTTP headers should be terminated with CRLFCRLF. These were terminated with LFLF.

 

for these sessions. So I found that by going to "Tools>Options>General" and setting protocol violations to "Do nothing", the "/ChromeExt/" warnings stopped showing up in the session pane and it is much cleaner.

So, these are warnings and not sessions showing in the pane.

Hope this helps - cheers!

Don't know that my post yesterday made it - is this what you're looking for Frederick?

This worked. Thank you. Those warnings were really annoying.

Hi Harry,

 

There is a solution shared by David Cain (use "Tools>Options>General" and set protocol violations to "Do nothing"). Does your case differ from the one shared previously? If so please consider providing a more detailed explanation of your specific case.

I just found this thread and can confirm this method resolves the issue.  Thanks!
