generally Chrome and IE&#x2F;Edge spawn separate processes per tab for isolation, but will sometimes group them based on some conditions. On the flipside I&#x27;d hate to have some 3rd party program bring down my browser.<p>So I get what you&#x27;re saying, but the worst case is that your browser will do the same thing for each tab.<p>Software like Excel which will spawn a different instance of Excel for each workbook, even though it could theoretically be a single process... so it&#x27;s not like native apps are a panacea in your argument.
