'Browser' is an English loanword that was adopted from English (from 'to browse' – to look around, scan through). It is fully established in German and is used like a German noun.
Welchen Browser benutzt du am liebsten?
Which browser do you like using best?
In everyday language, 'Browser' is often combined with verbs that describe actions involving programs: 'einen Browser öffnen' (to open a browser), 'starten' (to start/launch) or 'schließen' (to close), 'den Browser aktualisieren' (to update/refresh the browser), or 'eine Seite im Browser laden' (to load a page in the browser).
Du musst deinen Browser aktualisieren, um die neue Funktion zu sehen.
You need to update your browser to see the new feature.
As a masculine noun, 'der Browser' is declined in a sentence. Pay attention to the correct forms in the accusative ('den Browser') and dative ('im Browser').
Ich öffne den Browser und suche nach Informationen.
I open the browser and search for information.
search engine
'der Browser' and 'die Suchmaschine' both belong to the internet, but they have different jobs. A browser is the program you use to open and view websites. A search engine is a website or service you use to search for information on the internet. You often use a search engine in a browser. That is why the words are easy to confuse. In practical terms: Chrome, Firefox, or Safari are browsers; Google or Bing can be search engines.

Vor dem Online-Termin öffnet sie den Browser und gibt die Adresse der Website ein.
