Do browsers change URLs of saved bookmarks in response to 301 redirection?
I tested the web browsers on my computer and none of them changed the address stored in the bookmark.
- Internet Explorer 7 - no
- Firefox 3.0 - no
- Chrome 4.0 - no
- Opera 10.01 - no
How I tested
First, I found some addresses that return a 301. For example, google.com returns a 301 to www.google.com
In each browser, I went to the bookmark editor, and manually created a bookmark for the old address. I visited the bookmark, then looked at the bookmark's properties to see if the address was updated to the new address.
While working on this, I came across a similar Stack Overflow question you may find interesting: Client Web Browser Behavior When Handling 301 Redirect.
I don't think so. They could at least ask you couldn't they?
"Such and such a site has updated their url. Would you like to update your bookmark?"
