ENH: Arguments for firefoxprofile

[teunisv]

TLDR: FirefoxOptions instead FirefoxProfile

Main reason: we want to start firefox headless, for that we need access to arguments
those are accessible in FirefoxOptions not FirefoxProfile
and for more overal compatibility with chrome FirefoxOptions has my preference.

I know this cause issues for existing profile uses, but hope you will consider it anyway

No backward compatibility issues would arise if FirefoxOptions would be supported in addition to and not instead of profile, correct?

I would favour a change that allows with options (also for chrome) to allow options to be specified...

[teunisv]

Yeah its backward compatible if you find a mechanisch to extinguish the two

I use "with profile" for chrome as well (example headless), this also works for mobile emulation

|script         |list fixture                                 |
|add            |headless                                     |
|add            |disable-gpu                                  |
|$args=         |copy list                                    |
|start          |map fixture                                  |
|set value      |$args   |for|args                            |
|set value      |false   |for|prefs.safebrowsing.enabled      |
|$chromeProfile=|copy map                                     |

|script          |selenium driver setup             |
|start driver for|chrome|with profile|$chromeProfile|

[fhoeben]

Yes so that's why I though it would be good to support

|start driver for|chrome|with options|$chromeProfile|

(where its probably better to rename the variable to chromeOptions)
