If you’re a video fan and spend a lot of time watching online video, here’s a must-have Firefox add-on for you to play a particular online video at Firefox sidebar – YouPlayer. In short, YouPlayer is a video player with playlist which works on Firefox sidebar while you are surfing the Internet on the right.

How To Use YouPlayer

1. Firstly, install YouPlayer Firefox add-on. Upon installation, click on “YP” on the bottom right side in your Firefox browser.
2. To start to watch an online video, you can click on “Search” button in YouPlayer to search a video in YouTube, Google Video, Metacafe, DailyMotion or MySpace.
3. You may drag and drop a link or local files from hard drive into a playlist window. When you double-click of it, it will be loaded in the video window.
4. You can save the playlist and make it work as a bookmarker so you can always continue to watch the unfinished video in your playlist.

Previously, I mentioned about a neat Firefox trick that allows you to duplicate the tab on the fly by just dragging it to a new space. Anyway here what I failed to figure out, and thought would be cool to have:

1. Support Mac’s Firefox
2. Keyboard shortcut instead of mouse dragging

Thanks for readers tip-in, there’s work around for both now.

Firefox in Windows

[Mouse] – Hold Control, drag tab to new space.

[Keyboard shortcut] – Click URL (highlight), Alt + Enter

Firefox in Mac

[Mouse] – Hold Command, drag tab to new space.

[Keyboard shortcut] – Click URL (highlight), Option + Enter

Thanks Wendy, Jeniffer

Here’s a rather quick way to duplicate one Firefox tab to another without the need to open new tab, retype the url and wait for the webpage to load. All you need to do is hold Control (Windows) key, drag the current tab to a new place (you’ll see a + sign when you drag), release it and brand new tab is created with the exact same website. Little nice find by Ashish of Technospot.

This however, will only work in Windows. Holding Command key in Mac does not have any effect. If you don’t understand how this works, watch a video over at technospot.net.

Firefox tabs kept webpages organized within single browser, but if your tabs are overflowing your tabs bar, consider grouping them up with this Firefox plugin – Tab Groups.

Tab Groups allows you to group specific tabs together under one, and rename them to whatever you want. There’s also an indication telling you how many tabs under each group. But be warned, more tabs means your Firefox will likely to utilized more resources, thus performing slower.

Nice find by Technospot.

Facebook Chat is cool, at least it allows you to send instant messages to online Facebook contacts. However I’m not really a fan of the chat bar being at the bottom of the page, what if I’ve left Facebook but still wants to remain chatting with my Facebook contacts? If you are using Firefox, you can place the Facebook Chat at the sidebar.

Step 1

Look for Bookmarks on the top navigation. Select Organize Bookmarks…

Step 2

Click New Bookmark... tab and enter the following:

• Name: Facebook Chat
• Location: http://www.facebook.com/presence/popout.php
• Check Load this bookmark in sidebar.

Step 3

Launch the Firefox sidebar, click Facebook Chat and start chatting with your Facebook contacts within Firefox.

If you are regular Facebook who live and die by replying Facebook messages, checking on your friends’ profiles, updates and photos, etc, here’s a Firefox plugin for Facebook you should really look at.

Assuming you already have a Firefox 2 installed in your Mac:

1. Download latest Firefox 3 beta.
2. Double click to launch the installation dialog.
3. Drag the Firefox application to desktop (instead of Application folder)
4. Rename it to something else, Firefox-3-beta.app for instance.
5. Now drag the renamed Firefox 3 back into Application folder.

Double click on Firefox 3 and viola, it’s running with Firefox 2 safely untouched. To revert back to Firefox 2, just delete the Firefox 3 app.

[Firefox only] Screengrab! is a Firefox plugin that allows you to do printscreen of the website you are currently viewing, regardless it’s a selection or the entire website (that includes those you don’t see in the lower fold). The plugin is light, and taking the fact that when it had to printscreen a website with long scrolling content, blogs for instance, it didn’t take me too long. Screengrab! outputs the screen capture in either .JPG or .PNG.

You’ll need a Firefox browser to see Screengrab! in action. Definitely a very useful tool for web designers, developers and bloggers.
