Opera favicons & privacy

Wednesday, July 23, 2008 8:11:25 AM

, , , , ,

Opera 9.50 introduced new format for saving favicons to fix wrong favicons bug in previous versions. Opera now additionally creates idx file along with ico file to store favicon information. The problem with new format is Opera stores history of visited pages (including searches) in idx file and size will grow over time.

You can delete ico and idx files by enabling "History of visited pages" option in "Delete private data" dialog but it will delete all including favicons for bookmarks & personal bar items. (You can disable favicons completely. Tools > Preferences... > Browsing > Page icons > Show no icons)

To delete all ico & idx files except bookmarks ico & idx files (when you use "Delete private data" with "History of visited pages" option), set read-only attribute to bookmark ico & idx files in images directory inside Opera Local Directory. This will also prevent storing of history in bookmarks idx file.

This was one of the first methods I tried myself but unfortunately it doesn't work for me. The folder re-populates each time Opera is opened. The Read Only tick has become grey instead of black.

I presume this method still works for you Tamil? Is there a particular set of permissions that need to be in place for this to work as describe? Simple File Sharing is not activated. Apologies if this is leading too far off-topic.

EDIT:
It's ok I think I've answered this one myself:

Randy writes: Hi Tamil ... Currently using Opera 9.6 on a dual-boot that has both XP and Linux (Mandriva 2009 KDE 4.1.2). I've attempted to use your advice for saving Favicons (personal bar) from being deleted when using the Delete Private Data w/ "History of visited pages" option checked. On XP, your advice works like a charm ... changed the attribute to "read-only" and it works just fine. On the Linux side, however, changing the permissions (as root user of course) of both the .idx and .ico files to "Read Only" does not seem to work like it did in XP. Upon using Delete Private Data, all files are erased anyways. Any suggestions as to why? And, more importantly, do you know of a way in a Linux environment to be able to save Favicons (personal bar)? Your help and advice are greatly appreciated!

For your account, remove write permission to those files and try.

Randy writes: Hi Tamil ... Thanks for the suggestion! I think I actually tried that before but gave it another go morning on my Linux ... pretty much same result with all files being deleted. Interesting note is that I have a custom button - Delete Private Data and Exit - on a toolbar and when I use it, all favicon files remain. However, when I use the menu version - Tools, Delete Private Data - all files get erased regardless of the "Can Read" permissions set on each file. Further thoughts? MUCH Thanks!

randy writes: Hi Tamil ... I have another somewhat related question to Favicons and Security for you. From what I understand, when you select Tools - Delete Private Data (with all selections except clear email and wand passwords) - all Favicons (.ico & .idx), except those one may have marked as "read only," should be erased. On my Linux system, and I have similar results on an XP system, I've noticed something strange. Simply opening Opera (9.6 but also noticed on 9.52) with a blank page and then selecting Tools - Delete Private Data - and then exiting Operra, mysterious Favicons suddenly appear in the .images folder. The files below consistent appear on my Linux sys & they are slightly different on my XP sys). They are: http%3A%2F%2Fimages.google.com%2Ffavicon.ico http%3A%2F%2Fredir.opera.com%2Ffavicons%2Fwikipedia%2Ffavicon.ico http%3A%2F%2Fwww.google.com%2Ffavicon.ico images.google.com.idx redir.opera.com.idx redir.opera.com.idx For me, when I suddenly see Google showing up when it's not expected, I think of some sort of privacy issue. Also, the "redir" sounds very suspicious as well. Is Opera communicating/reporting data to the outside world without the user's knowledge??? Your thoughts please! Thanks!

It seems Opera is downloading search engine favicons when you use delete private data.

I see the link in the standard_toolbar (1).ini file but not where it references the image that it uses. The link is not in the opera6.adr file. Any help? Thanks!

Can you find line ICONFILE=

Check in Opera6.adr file. Otherwise, you have to add image to skin file and specify it in toolbar file.

You can disable favicons as shown in post. You have to RSS and widget icons from skin file.

You can edit those and/or block content. Some are: http://redir.opera.com/favicons/* Last resort, delete stuff from the icons folder and remove your write permission from it (Security, not read-only attribute).

Anonim writes: Does there exists an easy way to clear the Opera favicons directory (I'm Linux user), leaving just favicons of all the sites I'm keeping in my bookmarks? I recall, that when I just deleted "icons" sub-dir, then I lost all the favicons in the bookmarks, and I had to visit each site to retrieve its favicon again. Can the subdir be sweeped off the superfluous favicons without making such disaster?

See last paragraph of the post.
