This extension was amazing!- that is until the latest Google update when it stopped working. I think around May 18th Google updates to all new icons and this doesn't cover up any of the new ones now on almost any of the pages. Not the Google app launcher (waffle icon), nor the Drive or Gmail home page. But before that this extension was incredible.

Thank you, this is great!
Few things would make it even better:
* Gmail in-page logo
* Maps favicon
* Simpler logo for the extension itself (kind of ironic)
Do you have a Github repo to send pull-requests to?

Update: aha, I think I found the issue. Previously, I had the "unread message icon" setting enabled, which displayed the number of unread emails I had on the tab icon. When I disabled that setting, the gmail icon replacement started working properly. That setting is disabled by default, so it makes sense why no one else noticed that yet. Thanks to the dev for the responsiveness!

Original review: looks good and for the most part does what it intends to. The only issues I've run into are that this doesn't change the Gmail tab icon/logo on my browser, and the calendar tab icon can take a second or two to change when I open a new Calendar tab (if those things are fixed, I'll update my review accordingly). Until then, 4/5 stars
