it is great but when I add a search engine I can not give its favicon, it adds google favicon itself

Please add the synchronization feature for search engines, settings, popup menu style. Thank you.

Thank you for support Webextension. Looking for this addon for a long time.

Good update, thanks.

Thanks for this important work which also included a better option panel. You still managed to easily reuse FF's search engines. The elements are now individualized, which opens up new perspectives for future development:
1-Sizing icons according to their importance
2-Adding additional layers to icons such as the arrow at the bottom left of Windows shortcut to differentiate identical elements: between wikipedia of different languages, we would annotate their language code for example.

Other suggestions:
3-The right mouse button should be reactive also in the bubble
4-The bubble should be formatted freely in css.
5- A timer to automatically clears the bubble
About the right-button menu:
6-The three mouse buttons should be as reactives as in the bubble.
7-Should be inspired by the Quick Context Search add-on

great popup search addon
