Limited advertisements is acceptable by almost many users, but the number of websites on websites are increasing more as it is the main source for any website administrator . Some advertisements pops in middle of reading an article or watching a video on YouTube, some person starts talking about some washing powder or other something suddenly which makes us wonder from where the sound is coming from for some seconds and it became to wait for 5 seconds for watching a video which sounds really annoying as we don't know whether the website is really helpful or not. For stopping these kind of advertisements some of the nice developers had developed extensions for web browsers which when installed blocks almost(99%) all advertisements on a website, and the links are as follows:
Mozilla Firefox: ABP(Ad Block Plus) is the best extension for Mozilla Firefox, if you know how to install extensions for Firefox then its fine, or else click on Add to Firefox after which it downloads plugin and installs it automatically. After successful installation it asks for restart option which can be skipped and you can continue your browsing or you can restart if you want.
Google Chrome: Chrome ABP(Ad Block Plus) click on the link and install, if you are new for installing extensions on Google Chrome you need to sign in to your Google account and click on install button.
Safari: Safari Adblock(AdBlock) click on Get it button, after successful downloading install it by double clicking the file.
These plugins/extensions work for web browsers installed on Windows and Mac OS, recently ABP(Android ABP, doesnt need your phone to be rooted) plugin released application for Android Mobile OS where in it blocks all advertisements on web browsers in Android over Wi-Fi(I didn't tried it if anyone tried please leave a comment as it would be helpful for others, thank you in advance).
