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?"

Chromium doesn't, but there was an issue raised for this https://bugs.chromium.org/p/chromium/issues/detail?id=70377, which was closed due to inactivity and lack of feedback.
