javascript - How to change text of Element Inspector tooltip/highlight via Chrome Extension? -


i change tooltip text of of chrome's element inspector. (the 1 see within page when hovering node in tree view). want add additional information there.

chrome debugger highlight + tooltip

is somehow possible? not find information in docs.

alternatively creating new little tooltip @ corner of highlight rectangle (which not interfere existing one) fine too. hints & tips.

so answer "you can't in extension" (as in, modify dev tools tooltip).

charles' answer points a guide talks replacing chrome dev tools. it's possible using command line of chrome, it's not extension can do.

you can, however, inject content script in page mimic dev tool's highlighting. not integrated dev tools, might enough purpose.

you can take @ abp's implementation of element selection/highlight starting point. think it's in this file.
