How can I do that? Replacing in .desktop file does not work. It only changes shortcut icon to open the browser but not the active browser window icon.
I believe the icons live in the tor-browser/Browser/browser/omni.ja archive file. Open that and look in thechrome/browser/content/branding directory. Remove or change those image files or maybe rename the branding dir itself. Just to be safe, you might want to verify that doing this has no impact on your browser’s fingerprint (maybe one of the Tor devs can confirm this).
Thank you for you attention.
I opened omni.ja archive file and looked in branding directory, and replaced Tor icons with Firefox ones.
To ensure we’re identical to Firefox, I opened omni.ja archive of a fresh-installed firefox-esr package, which I could find at /usr/lib/firefox-esr/browser/omni.ja, and replaced icons in branding directory with other icons and launched Firefox. The icon next to “New Tab” was changed. This means there will be no UI difference between Tor and Firefox if Tor icons were replaced by Firefox icons (both found in branding directories in their respective omni.ja files)
Doing this, only the icon next to “New Tab” has changed, and not the window one. Do you have any ideas? Moreover, deleting branding directory completely results in a generic World Wide Web icon appearing next to “New Tab”, but the window icon does not change.
This is indeed paramount. I will only apply when I am informed by a Tor developer of the consequences. Do you think we should create another Topic asking specifically for this: “Security or Privacy implications of changing branding icons of a Tor Browser”?
