How do I update my browser on ipad? This keeps on happening

Then your browser is up to date. The browser is tied to the software and cannot be updated independently.

You could look in the App Store and see if there is any browser that can run on your operating system.

Here are a few third party web browsers that maybe STILL being updated and supported on iOS 10 and earliet

Available and more popular third party Web browser choices are pretty much GONE now.

Here's what’s maybe left.

iCab Mobile Web browser

Aloha Web browser

ALook Web browwer

Dolphin Web browser

DuckDuckGo Private Web browser

Snow Bunny Web browser

Maxthon Web browser

Private Browsing Web browser by Savvy Soda

Private Browser Deluxe

TOR browser anonymous

Turbo VPN browser

TOR + VPN web browser private

Pick two of these in the list that have had a recent or fairly recent app update. Do not pick a third party Web browser that has NOT had an app update in over a year or more.

Good Luck!
