Application Search Engines¶
Firefox defines various application search engines that are shipped to users.
The extensions for the definitions of these engines live in browser/components/search/extensions
It is preferred that each engine is shipped with a
.ico file with two sizes
of image contained within the file:
16 x 16 pixels
32 x 32 pixels
Some engines also have icons in browser/components/newtab/data/content/tippytop. For these engines, there are two sizes depending on the subdirectory:
favicons/: 32 x 32 pixels
images/: preferred minimum of 192 x 192 pixels
To update icons for application search engines:
Place the new icon file in the folder associated with the search engine.
Increase the version number in the associated manifest file. This ensures that the add-on manager properly updates the engine.
Be aware that the allowed-dupes.mn file lists some icons that are intended as duplicates.
To update icons for tippytop:
Place the new icon file in both the sub-folders within the tippytop directory.
