Command-line parameters

I started out just looking for a "safe mode" command-line switch, like all the other browsers have; e.g.:

C:\Program Files (x86)\Opera>launcher --disable-extensions

I couldn't find it.

So, my question is, where can I find documentation for Opera's command-line parameters?

I'm using Opera for Windows, version 63.0.3368.53 (about to restart to update to 63.0.3368.71).

The list of command-line switches / options / parameters for Opera used to be here:
https://www.opera.com/docs/switches/

It's gone, now. This seems to be the final version:
https://web.archive.org/web/20180412125335/https://www.opera.com/docs/switches/

It seems to have little resemblance to version 63 reality.

There's also a big list of Chromium command-line parameters here:
https://peter.sh/experiments/chromium-command-line-switches/

I've only tried a few of them with Opera, and I didn't find any that work.

A few command-line parameters seem to be recognized, even though they don't work right:

--version or -version or /version doesn't display the version number unless you redirect the output into a file, but it does prevent Opera from opening a new window

--help or -help or /help is similar. It doesn't seem to work at all if you run it via launcher.exe, but if you run the desired version of opera.exe directly, and redirect output into a file, like this:

"C:\Program Files (x86)\63.0.3368.71\opera" --help >tmp.txt

Then the resulting tmp.txt file contains:

Opera 63.0.3368.71 Stable

@ncdave4life Chromium command line switchers should work in Opera.

@leocg "should" .. but don't

e.g. this simple
C:\Program Files\Opera\66.0.3515.44>opera --start-fullscreen
doesn't work.

I would need to start Opera in batch mode to start with some pages and then "save as pdf" (then I convert with Xpdf to text and a small script greps the values into a .csv file).

Looks like I have to use Chromium for this.

Using Opera since version 6.

this will start maximized but not full screen --start-maximized

A Former User @fuzi1968

@fuzi1968 This will get full screen in chrome

I don't think Opera supports --start-fullscreen. Not sure if it's intentional or for some technical reason.

Maybe there's a workaround though.

Maybe https://www.autohotkey.com/ could be used to press F11 after Opera starts.

A Former User @burnout426

@burnout426 that example work with chrome ya gotta press F11 to get out tho..

ya know like "chome.exe" a space then chrome --start-fullscreen --app=https://google.com

chrome again w/o exe

fullscreen and not kiosk too !

Can not make it work with opera but does work with chrome

so @burnout426 i guess you're right
