It is generally recommended to use as few browser extensions as possible, as each extension gains access to certain areas of your browser and online activity. This can result in personal data being revealed or your browser becoming more vulnerable to attacks. It is therefore important to carefully consider whether an extension is truly necessary and if the permissions it requests are appropriate. It is also advisable to regularly review which extensions are installed and whether they are still needed.
