What would we do without bookmarks? With all the things we need to remember, not having to remember a site's address (URL) is a good thing, especially when the address is not as easy as "www.mozilla.org".
With the help of bookmarks, Firefox remembers your favorite sites for you.
To bookmark a page in Firefox, select Bookmarks -> Bookmark this page.
The "Add Bookmark" dialog will open, asking you where you want to save the new bookmark.
Select the folder that you want to save the bookmark to from the dropdown menu and click on OK. If you want to save the bookmark to the Bookmarks Toolbar, select Bookmarks Toolbar folder as the target.
Alternatively, you can also expand the menu tree, if you want to save the bookmark in a subfolder.
If you want to add a new folder, click on New Folder and enter the folder name. Firefox will create the new folder below the highlighted folder. Computer Repair and Computer Technical Support will always be provided at any time by Microsoft certified techs.
