I recommend you to create a Shortcut to a TestProfile with the switch "--user-data-dir=" and test in another profile without renaming every time. Here it's a post with some steps for other reasons but there are the steps to create this shortcut too to a TestProfile, mostly since step # 3, but read whole post may be needed to understand what it's doing.
No, people don't own anything to anyone, if they are using opera developer.
If someone is using an alpha version of a software (and developer builds are alpha versions of Opera) then s/he should, at least, knows what they are doing and the consequences of it. And also where and how to find info about new releases and its issues.
Haha, "don't add bookmarks", you're killing me with your hilarious jokes.
Good to know that you realized that it was a joke i did (or tried to).
For now you will need to move the bookmark to the folder you want.
I hope you realize, that messing around with firewalls is total bullcrap, and it shouldn't be so hard to just turn off the damn updates.
Blocking the autoupdater using the firewall is only one of the options, you can use the others.
And I don't understand, why is it so hard to make a checkbox in the browser options that turns off the updates.
It's probably not that hard but they don't seem to want to do it.
One reason i can think for it is: users will block the updates and forget about it. Then they will start to have issues because of new things being added to the web sites and will start reporting those issues already solved on a recent version of Opera. And dealing with those reports cost time and money for Opera.
Imho ("forced") autoupdates will be the default in the future. Even Windows is going this way.
PS: opera automatically updates itself (HOW DO I TURN THAT OFF BTW?), so today (atleast) I was using the latest developer 33 version, and ctrl+shift+T wasn't working untill I tried to reset the hotkeys (that is 100%)
Most important is that they use either a check box or a bookmark folder for speed dial. Previously, both options were combined, which was very confusing. Now they only use a bookmark folder for speed dial, and I'm, as @threatdown, very satisfied with that.
