Sometime it might happen that your system automatically get shutdown while working , restart again itself. I don’t need to tell causes of improper shutdown, right ???? It happened with me twice. First I thought it happen due to lose power connection problem or cable fault. I keep working on it then I realize it happen because some system files get corrupt. After that I reboot my system to recover that files. Now it’s working properly.
Lot of times system files get corrupt due to viruses and improper shutdown. So always shutdown your system properly and use real time antivirus software to keep your system safe from viruses.
How to boost the performance of your firefox
Monzilla firefox is one of my favorite browsers which have one feature pipelining which really make it really fast than another browser. By default it is disable, so make it enable to get good results.
Enable pipelining and increase pipelining maxrequests
Like in processors pipelines concept is there to fast execution of instructions so processor ultimately execute programs fast. Same concept is used in firefox to get fast result.
Open your firefox browser, type about:config in address bar. Then you will get filter option, type network in filter .then find network.hhtp.pipelining option in below list and make it enable by changing its value false to true. Just below that second option is network.http.pipelining.maxrequests, change its value 4 to 10 to increase pipeline maximum requests.

Are pop-messages safe???
Pop-up messages
When we are installing something in our system then we are always receiving some pop-up messages to keep that software updated. We are clicking on it for ok, cancel, not now, ignore, and ask me later, abort.
Sometime hackers send you such Pop-messages to hack your system. When you click on ok, cancel, not now, ignore, and ask me later, abort .these buttons include some different code that you don’t know. When you are clicking on any button, that code get activated and simply they hack your computer. Like this they hack your all data and everything.
For example, when you send any comment then I will get your IP address with that I can send any Pop message to hack your computer.
When you are not sure about Pop-messages then don’t click on any button.
