I want to use Opera GX but I've been using Opera Browser for years. All of my data are in Opera Browser and I have some doubts actually.

1- First and most important question: What will happen my data when I start to use Opera GX, I want to uninstall Opera browser and download Opera GX. There are lots of data on this browser, my accounts, extensions etc. I don't want to lose them.
2- Does Opera GX have workspaces? I use them a lot. I can't do without them.
3- I don't need sidebar extension of Messenger, Whatsapp, or Twitter. I only use Instagram on sidebar, does Opera GX also has this?
4- I use MyFlow extension to take some nots while I using Opera Touch on my phone, does Opera GX also support this?
And
5- Is there any problem with Opera GX that makes it hard to use, if I'll lose my data on Opera browser I don't wanna do it for nothing.

I've read topics about Opera GX on the forum, it seems it has some problems such as being out of sync, lagging, slow performance, crashing etc. Is it true?
Thanks.

@naheed Thank you for your help, now it works. I disabled and enabled it again.

This is a very good addition and I use it very much but I cannot turn down or up the volume. To volume up or down I have to use volume mixer of Microsoft, but that effects all of the tabs on Opera. Will you add an volume section to Spotify addition? It would be awesome.
