If all else fails, delete the speed dial, empty the bookmarks trash and the URL opera://bookmarks, goto the site and click the heart icon to add the site back in.

As I went through all the extensions in the old files, there were a couple named ones that I didn't recognize and wondered why they were there. They are WebRTC and HLS Downloader. Any ideas?

The export option only supports exporting everything, so you'll have to delete anything you don't want after importing.

If you want to create an HTML file with only certain bookmarks, you can import the HTML file into a test standalone installation, goto the URL opera://bookmarks in it, move everything to the trash you don't want, empty the bookmarks trash and then use the drop-down at the bottom left to export what bookmarks are left. Then, send and import that trimmed HTML file.

Whatever way is easier for you.

Q: Instead of syncing to a laptop, can the updated speed dial folder or the other SD one be exported, then emailed and copied into bookmarks/speed dial on my laptop?

First, where do I go to find the "right-click on the 'key' node and to choose "delete selected node" and "update_url" node?

To-Read Screenshot in Nedit:

However, you can do some manual work to get them back, but it won't restore their settings and data.

In "C:\Users\yourusername", create a folder named "Opera Extensions".

Then, in the "Extensions" folder in your Opera backup, copy (not move so you still have the backups) all the ID folders that are for the extensions you can no longer get to the "Opera Extensions" folder you created. You'll have to open manifest.json is each of those ID folders first to know what extension each folder is for. Skip the ID folders for Opera's built-in extensions and for extensions that you can just get from addons.opera.com or chromewebstore.gooogle.com again.

Once you have those folders in the "Opera Extensions" folder that you created, go into each folder and delete the "_metadata" folder if present.

Then, go into each folder and edit manifest.json with JSONedit in tree mode. You want to right-click on the "key" node and choose "delete selected node" and repeat for the "update_url" node. Then, save your changes. That way Opera never tries to update them and remove them if they've been pulled or blacklisted.

Then, in Opera, goto the URL opera://extensions, turn on developer mode, click "Load unpacked" and point it to the version folder in one of the ID folders (as in, the folder where manifest.json is at) in the "Opera Extensions" folder. That will load the extension. You can then repeat for the others.

Once you have the no-longer-available extensions loaded in Opera, you can install the rest from addons.opera.com and chromewebstore.google.com.

After starting Opera, you might have to goto the URL opera://bookmarks though and move things around if the old bookmarks and speed dials get treated as imported bookmarks because they were created by another Opera. But, that's not hard to do.
