@lh-mouse i must of got confused.

your right, i've just started up Opera with only the speed dial its its centered on screen not maximized. certainly not how i left it

[ubuntu 18.04]

@lh-mouse said in Opera doesn't remember window size and position if it was closed without any tabs (except Speed Dial) on Linux Mint:

I have a habit to maximize the window of my browser. Since on Windows Opera remembers its last-closed window status, I don't have to maximize it by hand every time I start it. However, on my Linux Mint laptop, Opera remembers window status only when it was closed with at least one open tab. In other words, if it is not the case, Opera always starts in a non-maximized, centered window. This seems a bug. Would you please fix it? Thanks in advance.

you can 'fix' this in the settings by ticking "continue where i left off'

[i realize its not a ideal way to fix it]

this has been around for what seems like years.

happens on Mint and Ubuntu for me

still does not seem to be fixed; i'm running Ubuntu 17.10 and no three buttons in the top right only the tab button

You may need to enable "Show advanced settings"

have you found it? and if so, which section should i be looking under after enabling advanced setting:

basic / browser / websites / privacy & security

in the settings i can't find it, where should i be looking?

i would love to know as well. if Vivaldi can do it so can Opera

i got this as well after installing opera on my mint systems. i found it just sorted its self out after a few minutes

Thank for your answer, but how I can disable flash in opera ?
In the extention I have no flash pluggin.

go to:

settings / websites / flash

then click on 'Block sites from running Flash'

as simple as that

try it with Flash disabled, worked fine for me
