I would like to delete some unwanted bookmarks

right click on the bookmark the delete it

Depends on the web browser.
Internet Explorer keeps them in a "Favorites" folder in your documents. You can go in there and just delete them.

Chrome - go to the menu, click "Bookmarks" and "Bookmark Manager."

Firefox, Ctrl-Shift-B will open up a bookmarks window that will let you manage your bookmarks.

Or, in most, if you open up the bookmarks window, you can right click on and delete the bookmark right there.

on my installation of Firefox, I just to show bookmarks - ctrl+shft+B - ans for example click on unsorted bookmarks, a list of bookmarks appears, and I click on the one I want to remove, and press the delete key on my computer, and it's gone, Click in red square at top right when you have finished to close the show bookmarks window.

Click on the Bookmarks pull-down. Right-click on a bookmark you want to delete. Select "delete" from the pop-up menu.

Hi
Not quite sure what you are asking -
Look for Manage Bookmarks in the Bookmarks menu
If you want to clear your search history it should be listed under History
If you have gotten an unwanted search with bing toolbar here is a link explaining what that is about:
Remove Search with Bing toolbar Virus Removal Guide
Hope this helps :-)

In the bookmark manager, right click on the bookmark and delete from the menu - or - highlight and use delete key.

From the bookmark list within IE, Chrome, or Firefox :
right-click the bookmark you want to remove, and select "delete".

You should be able to click on Bookmarks in the task bar on the top of your screen. Choose Show all bookmarks, open the bookmark menu or bookmark bar. Choose the bookmark you wish to get rid of, it will become highlighted, press Delete. Done.

Reinstall your browser. Or open the bookmark file in the browser, point to each one and delete.

Use the Manage Bookmarks (Firefox) or Organize Favorites (IE). A panel opens listing all your favorite bookmarks. Select 1 or a few (use the CTRL key and keep it pressed to select), then press the Delete button. Confirm the deletion. Move on to other favorites.
To add a bookmark/favorite: Open the page you want and press CTRL D. Give the bookmark a name or leave the default one and press OK. later on, when many favorites are added, you can use the procedure above Manage/Organize to open the panel, Create new folders, move bookmarks around. Close when finished.
