https://searchfox.org/mozilla-central/search?q=feedIcon&case=false&regexp=false&path= The jar.mn references + the files themselves can be removed. The other references (CSS and JS) can be replaced with chrome://browser/skin/feed.svg

what about these lines? https://searchfox.org/mozilla-central/source/browser/components/preferences/in-content/main.js#3207,3216,3225 I don't think so 'chrome://browser/skin/feed16.svg' will work?

When Firefox is compiled, the url is changed to chrome://browser/skin/feed.svg. If you type that link into your urlbar, you will see the correct icon appear.

How can I test for these kinds of bugs? How can I ensure that what changes I did those are correct? Any command?

The icon is used at different places in the UI: - https://www.reddit.com/r/firefox/.rss - about:preferences#general -> scroll down to "Applications" You need to manually check if the icon is correctly replaced in both of these links.

Hi Tim, Can I take this one too? Thanks!

Yeah, sure :) Please let me know if you have any questions.

So just to confirm, I should replace audoFeedIcon and videoFeedIcon with feed.svg as well?

I hit a snag, as part of bug 1491243 feed.svg was removed. Should I add it back, or how should I proceed if not? thanks! -jason

Let me know if you need help finding another good-first-bug. Sorry :(

NP, it was a learning experience at least :) If you know of another good-first-bug please send it my way thanks!

You can try bug 1491614, bug 1457782 or bug 1451715. You can look at this list if none of those 3 bugs interest you: https://codetribute.mozilla.org/projects/ff
