What files and folders should I back up?
The best thing to do is to backup the entire profile folder. If you want to backup something specific, please refer to http://help.opera.com/opera/Windows/2393/en/solutions.html#backup
Posting about your problem
After have done the steps above and confirmed that the problem is most probably in Opera, it's time to post about it.
Start the topic with a title that briefly describe the problem so people will know about what this is about.
Don't try to explain all the problem in the title.
Use tags to make it easy for other users to find posts about similar issues. If posting about Opera Mail then add the 'Opera Mail' tag
In the post (body) you should include the following information:
Your OS (Linux, Mac, Windows)
Your version of Opera
If the problem is with a page, a link to it
A screen-shot of the problem if it's related to something not showing as should
A description of the problem, including as much as information as possible
Steps to (try to) reproduce the issue
Expected behavior and actual one
I updated to 53.0.2907.106 several hours ago and this is still occurring. Typing in "dis" to go to discogs.com, for example, instead shows me a booking.com advertisement for "disneyland hotel", which is what is opened if I press Enter instead of the actual site in the omnibar. This has a disastrous effect on being able to rely on muscle memory while browsing.
If that wasn't the intended behavior, then I'm not really confident that the actual intended behavior is really any better. Adding sponsored links to Speed Dial was one thing, but constantly injecting ads and unwanted sponsored search terms into basic UI elements in response to user input is extremely intrusive and I'm strongly considering switching browsers because of this.
This is fixed in 53.0.2907.106
Before when I scrolled, it was only grabbing part of it.
Got the answer here, in a dupe post:
For some reason that post showed up in the results of my "snapshot" search, but not this one.
New update - Opera stable 53.0.2907.106 ;-)
The change log, and the announcement.
"Today we’ve prepared an Opera 53 Stable update. It contains bug fixes for your Speed Dials. They should no longer be able to double in your start page, and their images should refresh promptly.
In this build we placed also fix for Snapshot tool. Now the whole area will be captured, when scrolling.
With this version, we’re turning on the bookmarks bar by default. You can disable it, edit or remove bookmarks in Settings (Preferences on Mac) > Appearance > Show bookmarks bar."
If you connect directly to a (wired) network then Opera has to guess your location; if you have wi-fi then Opera looks at the list of hotspots your computer can see and asks Google where those would put you, And of course if you have some sort of cellular data card your carrier can tell them exactly where you are.
Last time I used my wired connection (ethernet) to my LAN they had me pinned at the local reservoir, about 4 miles away. On my laptop (wi-fi) they have me within 100 feet.
@juliandd One thing is not related to the other.
Opera Mail, the email client, allows you to access your email account as long as your email service uses POP or IMAP. If you will need to pay to use your email service or not is something you need to discuss with them and don't depend on the software you are using to read and send your emails.
Operamail, the mail service, is owned by Fastmail since a long time and only they can say if you will need to pay or not.
