Safari is quite slow when I open new tabs. I get a busy cursor, and I cannot interact with other tabs.

Is there any way to make it faster?

I have a 2010 MacBook Pro, MacOS 10.6.6, Safari 5.0.3.

What versions of OS X and Safari are you running? – Dori Feb 9 '11 at 6:44
I've updated the question. – yanis Feb 10 '11 at 1:10
How much RAM does your mac have? – hellothere Aug 20 '12 at 21:28

Install clicktoflash or some other flash blocking thing.

Also disable java and other plugins. These are particularly useful for Safari 4.

Here are some good tips on on speeding up Safari. Some of the tips are detailed below:

  1. Try dragging the folder Icons -- where these icons are cached -- within the ~/Library/Safari folder to the trash and restarting Safari.
  2. Try deleting ~/Library/Preferences/ if you are experiencing slow launches, but note that you will lose some easily recoverable settings, such as whether or not tabbed browsing is enabled.
  3. A blanket approach to deleting many of the potentially problem-causing items is the Reset Safari... command, available under the Safari menu in Safari. Note, however, that this command also deletes your browser history, personal data -- such as stored login passwords, search entries, cookies and more -- that you may not want to clear. Still, it's a good initial cleansing step. On recent versions of Safari you can select the kinds of data you want to delete/keep.
  4. Try temporarily disabling plugins to see if that's a potential cause. Go to the Safari menu within Safari, and select Preferences. Click on the Security tab and deselect 'Enable plug-ins'. Restart Safari and see if the slowness has disappeared. If it has then the problem is likely to be an errant plugin.

True, I think I was new to the site when I answered that. I've amended the answer with some of the more likely causes. Thanks – conorgriffin Aug 20 '12 at 20:18

First thing to try is to clear the cache and history, and restart Safari (and even your MacBook).
