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.

Be the first to make a post on your favorite discussion forum and inform other members and friends about this Forum Preview Extension.

Requirement : Recent or sufficiently fast computer with fast internet connection.

Install or Download

NOTE: If people like this then I will add support for other forum software too.


  • Inline Last Post.
  • Photo gallery from threads. Custom settings for Gallery. My Gallery (chrome only). Slide show.
  • Filter thread titles to ignore certain threads. (beta)
  • Image gallery from previous pages of selected thread. Turn this feature on when viewing thread about travel / tour trip or an event etc (beta)
  • Auto show new Posts and new Replies. (alpha)
  • Force show new Posts and new Replies.
  • Hide (fold) all posts. Quick toggle fold posts.
  • Avatar effects. (alpha – Google Chrome only)
  • New Post Counter. (beta)

  • YouTube – Top Comments under embedded player in forum. (Chrome only, vBulletin). Working on separate extension for this. That will work on all sites.
  • Ignore previewing ‘Sticky:’ threads.
  • Quick Delete of your post in vBulletin 4+ (Chrome only).

Note: Some of the above features are for vBulletin 3.x boards only. Added “Todays Posts” link on vBulletin 4 when signed in. vBulletin 4 (alpha). Click peace icon to open and change Forum Preview Settings.

News / Blogs – Features:

Original Concept. Action buttons, info panels and menus near top and on right edge of screen. Few years back I added new posts information box, easy (un-)fold posts controls near right-top edge for easy access. It seems that location and concept has picked up and lot of new sites are placing all kinds of menu or control options in that location (Area from top-right corner to [1/4 x screen-height] distance from top and on right edge). This is also used in my other popular extension Craigslist-Peek.

Avatar Effects: Works for vBulletin boards, when using Google Chrome (Firefox not supported at the moment) and have this Extension installed on it. See screenshot and See avatars p.l.a.y here. Leave a comment below if you need to create similar Avatar. Probably you will have to email me your Avatar image and link of the YouTube video. Follow these steps (on Windows computer) to modify your Avatar to add YouTube video.
1. Put YouTube video id/code in a .txt file. Goto C:\ directory and create youtube.txt file. Like this:
Here ‘zuCjHXLHGUk’ is video code that you can extract from YouTube video address.
2. Open windows ‘CMD’ console. Start->Programs->Accessories->Command Prompt. In Console type
cd \
and press Enter. Now suppose your Avatar image name is originalAvatar.png and its in C:\ directory. In Console type:
copy /B originalAvatar.png + youtube.txt newAvatar.png
That’s it upload originalAvatar.png to your vBulletin Forum and see if it worked. If the steps didn’t worked for you then just leave me comment and maybe I can do it for you.

Switch Forum Style. If it stops working on forum (e.g. vBulletin) then see if the forum allows you to change style(usually drop down style list is located at bottom of page). Try changing style.

Try it on discussion forums like :- (old format)

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.

Other extension that works well with this one:
– Craigslist car listing filter

Also created a related userscript that gives estimated cost of Importing US car or motorcycle to Canada.

Now this mashup is heavy but adding the enable/disable feature buttons is handy to manage the clutter and speedup browser load.

If the listing is in correct format then it will get that car’s model’s information from sites like MSN Autos,,,, etc.


  • Gives estimated price from multiple sources. Also provides links for further research.
  • Factory car recalls for the car model.
  • Consumer reviews, this is the real gem.
  • Car reliability information. It shows the msn autos page focused at reliability section. This shows what kinda engine problems occur in that particular car. Other info is also there but reliability info is most useful on that page. Takes like 2 sec to get idea of how reliable that car model is.
  • Scans the posting and shows a highlighted message on top informing about:- accident car, rebuilt car, moving sale, one owner, suggests buyer to ask if the car was involved in an accident.
  • Lists similar (year/make/model) ads from craigslist on top. This gives the idea of going price and the supply/demand.
