 Clementine Music Player :  Simply superb ! Nice interface. You can easily add media libraries. It is very easy to create playlists here. I love the "fading duration" feature in this music player.

VLC : All of my friends use this as it is very simple. In fact they learned all keyboard shortcuts for VLC and even tried them on other players and failed.

VLC works fine on Linux, Windows, Mac, iOS and Android .VLC plays most of the file types which makes it number one media player.Even if you already have VLC in your Computer, try to get a latest VLC download.

Browsing the Internet is what we do most of the time with our computers.Some times we forget some silly things and follow a long process to do a small task. So I am just reminding some tips for improving your productivity while browsing the Internet.
  • Don't go back by clicking 'back arrow' several times. Just right click on back button and choose which page you want to navigate
Right click on back arrow to get browsing history of the tab

  • Are you watching a long video on Youtube ? Are you reading a webpage for long time. Then why don't you go full screen ? hit F11 to concentrate on the content. This gives good browsing experience if you are using a small monitor.With full screen you can save some chunk of space in the browser.
  • Use Ctrl+shift+T to re-open closed(may be accidentally) window.
how to open  closed tab in firefox and chrome
reopen an accidentally closed window
  • Got a link to open in new window. What you do usually ? right click and select 'open link in new window'. But why taking two steps? I suggest you use Ctrl + single [left] click on the link to open in new tab.

  • Put a master password for your FireFox browser[read this] and relax. You just need to enter you master password for every browsing session, Firefox will not ask for user name and password for individual on-line accounts again. I save a lot of time by skipping the need to enter user name and password forms[without losing my security].
  • If you are browsing on public(not your own) computer then don't forget to use 'Start Private browsing' option in Firefox. Same can be done in Chrome using 'Incognito window'. This will not store any data or history of your browsing session.This option is best for doing bank transactions and logging into your on-line accounts.
