Highlight multiple keywords in a web page

When you look for some information in many posts, articles, or anouncements, it is handy to highlight relevant keywords in the web page contents. Now when it is trendy for the search engines to return inexact or irrelevant results, highlighting meaningful expressions saves lots of time.

A sample use case - searching for suitable job offers in LinkedIn. In the search results, the contents of the job posting rarely match the keyword in the search box. With this extension you do not need to read each post, you see immediately it is contains any keywords.

The extension is maximally simple to use. Enter once the keywords in the option page, and then click the extension icon whenever you look though the contents that are supposed to contain those text strings.
