javascript - Browser Extension - Pass address bar URL to API -

so i'm looking @ adapting simple extension myself. browse safari , chrome mainly, test in firefox , end using few days, wouldn't mind porting idea 3 forget it.

basically want automatically send every url browser visits via viglink rest-api. i'm going assume pretty simple, have no idea how address bar url , send , return change address bar url (in essence guess redirect via api)

the api check against database , if no matches found return standard url, if see's merchant return affiliated link. ensure i'd commission own browsing without remembering affiliate links via viglink (or skimlink) first forget.

so have simple browser extension set 3 browsers, html , javascript parts empty , have no idea how id need do.
