Every day I use Mozilla Firefox. Sometimes I find some plugin or some functionality that I previously did not know. Although there have been many things that I tested in Firefox, there has been one thing that called my attention. This is the HTML Validator - a plugin that tells you the errors and gives you information about the source code of your webpage or blog.
Thanks to the HTML Validator you know what is wrong with your blog and how to fix it. This is one of the things that, I think, makes all the difference between Mozilla Firefox and other browsers, like Internet Explorer or Safari. Other browsers never point out the mistake.
To install this add-on in Firefox, all you've got to do is follow these steps:
- Click on this link -> https://addons.mozilla.org/en-US/firefox/addon/249
- It will open a new window / tab, where you will see, among other things, a white box in which it says "Add to Firefox". Just click on it.
- After that, a window will open with this addon, and in the lower right corner you will see a counter. When the loading is finished, you can click "Install". The process of installing the HTML Validator lasts a few minutes, depending on your network / internet speed.
- Finally, after installation, you will be asked to restart Mozilla Firefox. There is no need to worry about losing the tabs and windows open, since during the opening of the new Mozilla Firefox, you will find a small window that will ask if you want to restore the previous session. Thus you will not lose any information.
Once installed, to use the HTML Validator, you must go to any website or blog, and right-click somewhere in the blog that does not contain a link. That will open a menu, where you should select – "view source". Following this, a new window will open, which will have three sections. At the top of the screen, you will find the source of the page, whether CSS, HTML, XHTML etc. The numbered lines will be there on the left. In the bottom left, there is a table where the HTML Validator will show the list of bugs, suggestions etc. The HTML Validator will also tell us the type of error, the line where the error is found, the column and the name.
You can see another section at the bottom right, indicating a legend like symbol that appears in the bottom left. However, do not click on any error or information at the bottom left, because that will tell you just what the error, or observation is. In addition, HTML Validator can show an example related to the error, and can indicate a possible solution as well.
HTML Validator is very useful for people new to creating blogs, and it helps you find errors in the source code of the blog, which you might not detect initially.
