Google usually comes up with many results that lead to PDF documents. That is annoying when you are specifically looking for websites pertaining to the searched topic.

Using the search parameters or the advanced search on the Google website, you can restrict your search to specific file types. You can also exclude individual types from the search results. For that, open google.com and click on ‘Advanced search’. Enter the search terms in the upper fields. Then select the ‘don’t’ option in the ‘File format’ combination field and then select the setting ‘Adobe Acrobat PDF’ in the combination field at the end of the line. Then click ‘Google Search’ and the search engine will give you the filtered result.

It can be faster if you enter the search parameter directly in the input field. For that, type the following command after the search term: -filetype:pdf The keyword ‘filetype’ and the preset minus-sign ensure that PDF documents are excluded from the search.

Firefox supports tabs that are used to open multiple tabs within a single browser window. You can also have the option here to open multiple home pages in individual tabs at once.

• Select 'Tools > Options'
• Select the 'Main' tab
• In the 'Startup' group, select 'Show my home page' from the 'When Firefox Starts' drop-down list
• In the 'Home Page' section, type in the name of the sites you wish to open by separating
  each one with a '|' (vertical line or Pipe)
• Click 'OK'

The next time you open Firefox all these sites will load automatically.
