Basically, yes. Or use the stable version of Opera

Because the majority of visitors from the same IP range is selecting that language, so the site is setting that language for everyone using the same IP range.

Same here, and even in Opera 55.0.2994.37 the problem isn't fixed yet. But it came up like 2 months ago and i am using Opera for 6 months now (I've always kept it on the latest version so it didn't came up at the same time you guys experienced this issue, which is quite strange.

@smnstrk I like your sense of humor!

@l33t4opera said in New Opera developer 56: Fix on focus in the address field, when opening new tab. Yay!

There are more recent topics on it already.

New update - Opera beta 55.0.2994.34;-) The change log, and the announcement.   Important fixes: - [Linux] Middle click the ‘new tab’ button should paste from primary buffer. - [macOS 10.11] Crash on Keychain authorization. - [Win] Missing options on the new Settings page: “Disable tab bar’s top spacing, when browser window is maximized”, and “Enable search box in the address bar”. - Missing translations on the new Settings page."   The Chromium has been updated to version 68.0.3440.84.    

@opaco https://blogs.opera.com/desktop/ is a mandatory reading for those using Opera developer. You will find your answer there.

Also, discussions on Neon belong to the topic you mentioned and requests have a proper forum for them.

@robinnyan Discussions on Néon belongs to https://forums.opera.com/topic/18833/new-opera-neon-concept-browser/191

@opaco It was never possible to set a custom search engine as the default one, so most probably the option to do it is a bug in the new settings page.

New update - Opera beta 54.0.2952.43;-) The change log, and the announcement.   "Thank you very much for your feedback about the bookmarks bar. Please help us to improve it. There are two cases, which will prevent unexpected changes to your bookmarks bar. The first is that you have manually turned off the bookmarks bar. The second case is, that you have removed the suggested bookmark links, which popped up recently. If your bookmarks bar is still experiencing unexpected changes, please file a bug report so we can fix the problem for all users. This update includes also a few bug fixes, such as: - Renderer crash, after changing zoom level on the page. - The icon changing, when renaming a folder in the bookmarks bar. - Wrong Speed Dial title font colors."
