Hi Jazovo,
Thank you for participating in the Apple Support Communities.
If Safari on your iPhone 6 Plus is quitting on a single LinkedIn page, even after updating iOS, try clearing the browser history and website data as well as adjusting the JavaScript and cookie settings on your device. You can use these steps from Safari web settings on your iPhone, iPad, and iPod touch:
Clear information from your device
To clear your history and cookies from Safari in iOS 8 or later, tap Settings > Safari > Clear History and Website Data. In iOS 7 or earlier, tap Clear History and tap Clear Cookies and Data.
To clear other stored information from Safari, tap Settings > Safari > Advanced > Website Data > Remove All Website Data.
Clearing your history, cookies, and browsing data from Safari won't change your AutoFill information.
Block cookies
To set whether Safari blocks cookies in iOS 8 or later, tap Settings > Safari > Block Cookies and choose one of the following: Always Block, Allow from Current Websites Only, Allow from Websites I Visit, or Always Allow. In iOS 7 or earlier, choose Never, From third parties and advertisers, or Always.
A cookie is a piece of data that a website puts on your device. Using cookies, the website can remember you when you visit again, and the webpage can be customized for you based on information you might have provided. Some pages might not work unless you accept cookies. For instance:
- You're unable to log in to a website or webpage using your correct username and password.
- You see a message on a webpage that cookies are required, or that your browser's cookie functionality is turned off.
- You try to use a feature on a website, but it doesn't work as expected.
Allow JavaScript
JavaScript is on by default. To change your settings, tap Settings > Safari > Advanced and turn JavaScript on or off. JavaScript lets web programmers control elements of the page. For example, a page that uses JavaScript might show the current date and time or cause a linked page to appear in a new pop-up page.
If you disable JavaScript, you might prevent some unwanted pop-ups. But you might need JavaScript on in order for some websites to work.
Thank you for including the detailed steps to reproduce the behavior for the community.
Best Regards.
