YouTube Top Comments extension

YouTube Top Comments is a Google Chrome extension that shows (site embedded) video’s Description, Rating and Top Comments on any website. Gives more relevant information about the video clip.

Try different DISPLAY MODES from extension settings to suit your liking.

Install or Download


  • Allows selectively disabling YouTube Comments on particular websites.
  • Shows video’s Top Comments, Rating and Description in compact form under video clip. You don’t have to go to YouTube site to read more about clip as the information is made available right where the clip is embedded.
  • Try different display modes from Settings (click Youtube icon in address bar).

I originally created this feature first for my Forum Preview extension. After some use realized that it is useful and is better as separate extension.

Fix URL Link Redirect – extension

Fix Url Links Redirect Google Chrome extension (1) removes the URL link redirect and takes you direct to destination. Remove the middle man and tracking. Second feature is (2) remove link Referrer.

Two Modes

  1. Work on All redirect links (except ones in ‘disable’ list).
  2. OR work Only on specific links/sites that you added to its ‘enable’ list. This is default setting.

Try both methods and see which suites you. You train it by adding links to it as you use it.

Install or Download


  • Fixes URL links redirect. Allows selectively disabling/enabling fix URL redirect on particular websites.
  • Removes link ‘Referrer‘. Its a totally separate feature than fix redirect. It can be disabled in extension Options.

Positive side-effects:

  • Removes middle-man / tracking as side effect.
  • Quicker page load.

How to use it:
If webpage didn’t behaved or loaded as expected and there is a fix-url icon in Address Bar then click that icon and add the suggested URL to the disable list. As you use the extension more the need to add sites to disable list will get less. Manage list of URLs for which this extension is disabled in extension Options.

  • Dark/black icon in Address Bar => extension is disabled.
  • Dull Brownish icon in Address Bar => extension detects redirect but it didn’t fix as site is not in its list. Click on icon to add/remove site.
  • Red-black icon in Address Bar => extension fixed redirect link.

Why remove HTTP Referrer
When visiting a webpage, the referrer or referring page is the URL of the previous webpage from which a link was followed. Most web servers maintain logs of all traffic, and record the HTTP referer sent by the web browser for each request. Technically the effect of this extension’s ‘remove Referrer’ feature is similar to attribute rel=’noreferrer‘.
For example, if you are looking at website and in there you click a link to another website say Now cocacola site will know that you were viewing BBC website. With this extensions ‘remove referrer’ feature the cocacola company won’t know what website you were viewing.

Note (Sept, 2013), Yahoo changed its website design. So the scenario shown below in screenshot no longer works on Yahoo. Later on, I will update screenshot to a site where you can test the extension.

Craigslist Peek extension – image preview

Craigslist Peek is a Google Chrome and Firefox Extension for Craigslist, kijiji (US), eBay Classifieds, 58 同城 and Facebook Marketplace listings page. Craigslist Peek shows Post and Image Preview.


  1. Google Chrome Extension / Web Store (new features and issue-fixes first come here in Chrome and then in Firefox after month or so)
  2. Firefox Addon :
  3. Safari Extension version coming soon. Both Firefox and Google Chrome versions works in Mac, use them for the time being.

I created this from my other Craigslist extension for cars section. And hence Suggestions feature in the cars and motorcycle section.


  • Short description under listing
  • Images under listing
  • Multiple Cities listing. Widens your search area to include neighboring cities.
  • Photo gallery
  • Suggestions in cars & motorcycle section
  • Minimum model Year filter cars & motorcycle section
  • Auto refresh. Shows new posts on top. New post counter.
  • Expands messages in craigslist Discussion forums (beta)
  • Filter craigslist search results (beta)
  • Split listing to Multiple Columns (chrome)
  • Fold / expand listing. Quick toggle fold posts. (chrome only)
  • User can customize looks of it to their taste

I removed some features to keep it simple and practical. Later on I might add some features for particular categories of Craigslist.

Seems new changes in Facebook Marketplace are identical to how I was changing Facebook Marketplace with this extension, so now disabled other stuff and only doing image preview in this.

It looks like some sites (Google News : and others) have now adopted similar concept to what I been doing in Craigslist Peek and Forum Preview. In these when a person clicks on a Post, it opens in a new-browser-tab. This saves you from clicking Back and re-loading the listing after viewing Post.

Usage Tips:

  • Enable / disable multiple cities or auto-refresh in Settings according to your need.

Fast computer with fast internet connection.
