Safari is consistently buggy and laggy for me when I'm browing the web, and I'm getting this weird light gold tint on the upper right hand portion of my screen whenever I boot it up.

Are you using the Mail app that comes with iOS ,
or are you using a different email program that you are trying access via a web browser ... Safari, Firefox, Google Chrome,... ?
if not using Apple's Mail app, the only way you can get access to email is to go to your Internet Service Provider's (ISP's) web site and login to your email program (e.g., Gmail) from there, or use an app for your specific email program ... e.g., the Gmail app.

How to Turn Off Split Screen on iPad Split View is enabled by default on the iPad. To utilize the feature, you can drag an app from your dock to the right or left edge of your screen to open the app on a portion of the screen. If you have multiple apps open and want to close one without turning off the Split Screen or Multitasking functions in settings, you can return to a full-screen view of a single app by dragging the edge of the app you want to remove to the edge of the screen.

If, however, by "getting rid of split screen on iPad" you mean turning the feature off completely, that's something you can do in Settings. To turn off split screen on the iPad:

• Open the Settings app on your iPad.
• Tap General.
• Select Multitasking & Dock.
• Toggle off Allow Multiple Apps.

How to Get Rid of Split Screen in Safari on iPad Using split screen in Safari on iPad was a new multitasking feature for iOS 10 that continues in iOS 12. This allows you to open two separate Safari web pages simultaneously on your iPad. To start, open Safari on the iPad. You can then open a second Safari tab in split screen in one of four ways:

• Tap and hold a link; select Open in Split View.
• Tap Command+N on an external hardware keyboard to invoke Split View.
• Drag a tab from its space to either the left or right side of the screen to open it in split screen.
• Tap and hold the icon that opens your tabs view in Safari. It looks like two overlapping squares. When you tap and hold, options will pop-up. Select Open Split View.

But what if you want to get rid of split screen in Safari? What if you're done using the two tabs-how do you turn split screen on the iPad off? To close split screen in Safari on your iPad, you can do one of the following things:

• Drag the tab(s) from one of the screens to the other. Once the last tab has been dragged to the opposite side, Safari will return to full screen, which will turn off split screen.
• Or, you can tap and hold the tabs icon, which looks like two overlapping squares. Then select Merge All Tabs. This will merge all your Safari tabs back into a single window, which gets rid of split screen.

First question do you use the Facebook App? If so you will need to log out of not only the safari Facebook page and also the Facebook App too or it will remember the account that you are logged into on the App or on Facebook. But another thing you will want to do is clear the cache/history out of Safari. To clear the history out of Safari you will need to start safari and then click on the open book icon, then make sure the open book is again selected near the top left and you should see a star with favorites, a clock with history next to it. You want to touch history and and then in the lower right corner hit clear, then another prompt will ask you what part of the history you want to clear. I would recommend selecting clear all history. Finally, hit Done in the upper right corner. Now Safari will not remember your last facebook login assuming you logged out and your facebook app is logged out as well.

Open Safari.
Click "Safari" in the upper left of screen.
Choose "preferences".
Click on "Privacy" and make your choise.

Go to Settings, then Safari, select Passwords & Autofill, select Saved Passwords, tap Edit in the upper right corner, then check the box next to both https://www.facebook.com and https://m.facebook.com, then tap Delete in the upper left corner. This will disable automatic fill-in of the username/password fields when logging in to Facebook using Safari.

There is a tab over the web site, and in the left corner a circle with an x in it. Press this symbol, and the web page will close.
On th iPhone you need to press the symbol with two squares in lower right corner to get to the tabbed pages.
