With Opera 46 through 48, clicking on the Edit buttons in order to update your e-mail address or password on Amazon.com causes the browser to crash.

Okay, thank you.
I rebooted and got the same problem.
In fact, I even get an error from Opera when I try to view those images, directly.
I'll have to do some more troubleshooting on my end, I guess.

That's what I see in everything except Opera 45.0.2522.0 (PGO). Are you using the same version?

Here's a screenshot to demonstrate:

Sorry, the forum decoded what I posted.
The second link should be the following:

http://schvenn.wdfiles.com/local--files/shows%3Ablacklist-redemption/blacklist-redemption.jpg

I'm not sure if that will work, but the colon between shows and blacklist is urlencoded to %3A , which won't display properly in this version of Opera.
For more examples, you can see them, here:

Take a look at the empty image on this page:

http://www.schvenn.net/shows:blacklist-redemption

You will see that the image should look like this:

http://schvenn.wdfiles.com/local--files/shows:blacklist-redemption/blacklist-redemption.jpg

Now, this used to work and works in every other browser.
However, because the file is uploaded like this:

http://schvenn.wdfiles.com/local--files/shows%3Ablacklist-redemption/blacklist-redemption.jpg

Opera cannot decode the %3A properly and thus doesn't recognize that the URLs are the same.
Chrome and other browsers however, do.

I love that you can get to everything from bookmarks to history, tabs, downloads and news from the start page, but for some reason the extensions page has been left out. I'm not sure why, but it would make a great addition.
