I forgot to note, I liked the Dark Style everything had, now it's all stark white, even the bookmarks menu! Change it back, or add a old style theme!

A little more information might be needed such as which device you are using. Perhaps submit a formal bug report so that the developers have a little more information to work with.
Opera Mini is working fine here on both an iPhone SE and 6S Plus which both updated to iOS 11 without any noticeable problems.

iOS 11

Iphone 6S

iPad Mini 2

Both worked fine before update.

Cause of Crash: The developers did not update the app to 64-Bit Architecture, which is NOW REQUIRED IN APPLE PRODUCTS as 32-Bit was dropped in this update.

The app can’t even be opened! Update it ASAP!

Its just like every other app-they want to look like chrome so bad that they ignore feedback.

If you want that crap news out of the way, do as I did in this picture: https://imgur.com/a/uT8OA

Ducky, although it's not a full solution, what I did to get the news off the start page was to create endless quicklinks of google's homepage until I couldnt see them anymore.

Agreed completely. This update was bad. Seems like everyone wants their mobile browsers to look like Chrome these days.

This update is HORRIBLE.

You've crammed the main screen with news I don't care about and squished my quick links into a TINY space!
I LIKED the sleek, grayish silver colors of the app! This White/Red setup makes it look like every other app out there!
Put the news where I didnt care about it before v16, in it's own page!
Put my quick links where they were before v16!
Stop changing everything without consulting your users!

I think I've determined two possible sources of the crashing, both related to the change to display margins in iOS 10.3:

1. The site I read Fanfiction at, Fanfiction.net, has added an animated advertisement on several of it's pages. This ad interferes with the app in several ways, one of them being any drop-down menus are immediately closed while the ad is playing.

2. As I stated earlier, iOS 10.3 changed the display margins for page views, which caused a significant number of apps to not function properly until they were updated.

As an avid fanfiction reader, I need the bookmarks to avoid the garbage that permeates the sites.

No, because I have no idea if mini would truly preserve my 1300+ bookmarks.
