You can have as many browsers as you wish. At the moment I am using Opera which I downloaded last Saturday to see if I could establish what you required. Top marks to SlackAlice for having provided the best answer.
I am Not too keen on Opera (the Browser) and shall revert to using Firefox. Nevertheless, I shall leave Opera in my Computer as an alternative; along with SeaMonkey; Safari; Internet Explorer; and my all time favourite...Firefox.
Always download from official sites because nasties can come along with
genuine items from 'Agency' sites.

PS. Opera would Not let me post into AB so I have done a quick copy & pasted into Firefox.
