Broken icon in Firefox 58.0

[anon88391]

The extension icon is bugged and entirely white in the newest Firefox 58.0.

Could you please right click on the icon and select "Save error log"? Having the log here definitely helps.

I noticed, because of privacy.resistFingerprinting , you can chang it to false in about:config.

Firefox 58 warns you if sites use Canvas image data

@FelisCatus 扩展图标是用了 Canvas 相关的东西吗？

SwitchyOmega is using canvas to draw icons and apparently that's what broke it. A canvas is needed because the icons can come in any color combinations.

In other browsers blocking canvas data, SwitchyOmega will fall back to the static, non-color-changing icon if it throws when trying to access canvas. Firefox is the first browser I've ever seen to return a blank image instead and I don't know what to do now.

Please see the Firefox issue here: https://bugzilla.mozilla.org/show_bug.cgi?id=1412961

In v2.5.10, the SwitchyOmega icon will stay the default blue icon if you have privacy.resistFingerprinting set to true. It won't change based on profile colors but at least it won't become empty.

I believe this is fixed in Firefox 62. Note that it can still fail on modified / flagged versions of Chrome that disables canvas even for extensions.
