Preference to disable favicon animations

[Dariush]

As is common knowledge, animated favicons are pointless (in most cases) resource hogs. There's a 17-year-old issue on Mozilla without any resolution, so I'm not the only one wanting to see an option to have them static.

[Moonchild]

So, you're saying a 16x16 animated favicon is a resource hog?

[Dariush]

When I have 20 tabs open of a site with it and this results in idle CPU usage of 5% (~50% of one core)? Yes.

[Moonchild]

If the animation of images bothers you, use Shift+Esc in Pale Moon to stop everything (including animated images and background network traffic)

[Dariush]

Doesn't work (in new profile) and even if it did, this would be a pretty suboptimal workaround, since I want _only_ animated favicons and no other images stopped.

In fact, this is a very serious and annoying problem. Personally, I even had to completely filter out with uBlock a few of these favicons from sites that I visit more or less often, because they cannot be stopped using Shft + Esc or in any other way.

[Moonchild]

Okay, I guess it's possible to do this by using a cropping function to create a new image to use instead of the actual favicon, since that will effectively take only one frame.

I actually tried this, but it didn't work. I get the uBlock warning page "disable temporarily/permanently" when I manually view the image, but it doesn't affect it being used as the favicon on the site. Could you elaborate what you've done to achieve this?

I actually tried this, but it didn't work [..] Could you elaborate what you've done to achieve this?

For example, I use the following rule for Dynamic filtering:

Code: Select all

behind-the-scene http://westsat.net.ua/favicon.ico * block

And after that, you need to wipe the browser cache.

Tracking this in Issue #899 (UXP).
I have a good idea how to approach this and should have a patch soon enough.

[Dariush]

I tested the new preference and it doesn't work*. On a clean profile most sites (Google and this site are the only exceptions among a dozen tested) simply get no favicon at all. On my main profile I have an addon called TooManyTabs which temporarily changes favicon when I mouse over a tab and back on mouseout, and when I do so on a site with a normally animated favicon (that doesn't initially get a favicon when this pref is enabled), the normal animated favicon loads upon the mouseout event.

Please also consider disabling the loading/spinning wheel icon with this option (it is technically an animated icon, right?) or create an additional option for it.

Thanks, I wonder what that massive string actually means. I already use the one below successfully, just thought it'd be a nice customisation option to have natively (and is semi-related to this thread).

Code: Select all

/* Disable tab spinning wheel */
    @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");
    .tab-throbber {
      list-style-image: url("chrome://mozapps/skin/places/defaultFavicon.png") !important;
    }

It's a data URI, which is a way to define a raw image (or other data) with a URL. Basically, this will replace the spinning icon (or "throbber") with the un-animated download icon.
