[!TIP] Enabling weather =>

In about:config make this true =

privacy.userContext.enabled

toolkit.legacyUserProfileCustomizations.stylesheets

[!NOTE] Disable "personalize-button.css" in the configs (just delete the file) so

the pencil icon get shown up in the home screen,

then toggled-on the weather widget then enable the file again (restore the file).

the running knight is also only get shown in the currect position if the firefox is fullscreen, if nnot it will be displaced (i will fix it someday 😇)
