This is a bad method. Let's say I copy an address to my clipboard I want to send some coins to. As soon as I do, some clipboard malware I am unaware of changes it to a malicious address. I then go to my browser and paste the address in, which has now been changed to a malicious address. I now want to double check the address. I hit "Find in page", I go and copy my original address again, the malware again changes it to the malicious address, and I paste the malicious address in to the search box. The malicious address in the search box matches the malicious address in my browser, I hit send, and I lose all my coins.
Some may call it bad method but I always check the address from where I copied it so that I would know if the address I just copied is the same as the original address and not the address from a clipboard malware. I don't know about you guys but this method help me know if my clipboard is affected by a malware or not affected. I don't seem to have problem with it since It also serve as a clipboard malware detection.

-Newbies- or experts, wallet transaction or just sending a message to someone, continuous convention/custom to rechecking things before sending, reading and grabbing or even writing to post, would be of whoever does it use, furthermore don't only check the address, I know a friend who has over sent more crypto-currency to a receiver than he wanted to send, even transaction fee. I think a curious and very sensitive -Newbie- would always recheck all this information before sending, no matter how basic this advice is.
Another way to check if your address is wrong or some characters are wrong then I will use "CTRL + F" or go to 3 dots at the upper-right side of the browser then choose " Find in Page" then paste your address and see it if will highlighted all the characters in your address.

If using a qr code that contains the address that the btc will be sent is I will use online qr core reader since it is an address not a seed phrase or a private key. When withdrawing from an exchange is I always check the address three times before pressing the send button or withdraw button.

This mostly works on exchange opened in browsers but for those who used apps will not work.
It is very convenient to use the QR code, but I don’t know how to check whether the QR code is correct.
There is no easy way to confirm a QR code itself is correct, and indeed, there exists malware which can change QR codes and display malicious ones with different encoded addresses. If you do use a QR code to scan an address (or transaction, or anything else), it is good practice to manually check the address which is then displayed in your wallet as discussed above before hitting sign/broadcast/confirm/whatever.but most mistake newbies make is trying to type a bitcoin wallet address
I very much doubt any newbies are typing addresses by hand, and especially not "most" newbies. As nc50lc has explained, typing an address by hand is very unlikely to lead to loss of funds due to the checksum built in to bitcoin addresses. Base58Check addresses have a 4 byte checksum, meaning that a typo only has a 1 in 4,294,967,296 chance of creating an incorrect but still valid address. Bech32 checksums are slightly different, since they are designed to identify the errors rather than just throw an invalid address error, but they also guarantee a failure rate of less than 1 in a billion. 
The best way when sending someone your bitcoin wallet address is to copy and paste it, but most mistake newbies make is trying to type a bitcoin wallet address which sometimes may not be exactly the same and correct because of its mixture of both lower and upper case alphanumeric letters, especially the P2PKH, P2SH and Bech32 wallet addresses and may lead to lost of fund.
It's indeed advanceable to copy paste addresses, then double-check.However, the statement about "most mistake by newbies" leading to loss of funds due to typo error as the isn't correct.
Because there's a "checksum" in addresses whether it's P2PKH, P2SH or Bech32, so if at least one character is typed incorrectly, the user wont be able to click 'send' at all
unless the wallet is poorly designed or the person is just extremely unlucky that he typo~ed a valid address.
BTW, Bech32 can only be either all upper-case or all lower-case characters, not mixed.
In addition to the correct address, you also need to choose the right type of public chain, such as ERC2.0, TRC, BSC, HECO, etc.

So it's advisable you do Copy and pasting, to avoid further error. Thanks

Most time because of the lent in the numeric of wallet address most newbies and even old members sometimes make mistakes in wallet address which often time lead to loss of the fund and be aware of the irreversible nature of cryptocurrency transaction to avoid this always make sure you double-check the wallet address properly before clicking send.
It is important to check the address. Once the wrong address is sent, it cannot be retrieved.I copy and paste again, and then check the address to prevent clipboard malware.
It is very convenient to use the QR code, but I don’t know how to check whether the QR code is correct.
Any time I am sending coins from any wallet I physically place the address I know is correct directly from the source, right next to the address I have entered to send to. That usually means either holding my hardware wallet or phone up next to my computer screen, or resizing two windows on my phone or computer to put the two address physically right next to each other. Once you have two addresses which are less than an inch apart, its very easy to check the entire address and not just a few characters at the start or end.
I've never understood why we tell newbies, or anyone else for that matter, to only check a few characters of an address. Checking a few characters is not a foolproof way to protect against clipboard malware now, and it will become even less reliable as time goes on, malware becomes more complex, and vanity address generators become more efficient.
It is not time wasting to check all characters of an address. If I withdraw my Bitcoin from exchanges, I would like to check it two or three times, depend on each exchange confirmation process for withdrawal.- 30 seconds for one checking time.
- 1 min 30 seconds for three checking times.
- It is worth to make sure I don't make any mistake for my withdrawal.

We tell people to spend hours learning how to verify software, read user guides, familiarize themselves with every aspect of bitcoin. We tell people to spend their money on hardware wallets. And then we tell them to save a few seconds by not checking the full address?
Here is what I do every time I make a transaction. It takes less than 10 seconds:

Most software alerts you where you are sending your funds, the fees that you included and how much Bitcoin. You need to use this alert to double/triple check the outputs and fees. Many people send to much in fees and could pay less but wallet software usually makes the fees higher than the current average fee on the blockchain. I do not know why they are doing this it might be intentional to stop people complaining about transactions taking to long. The address you need to check either letter by letter or use neuroticfish's suggestion to check a number of characters at the start, middle and end.
or check the first, last and one middle 3 characters
I always check first 3-5 chars, some 3-5 chars somewhere in the middle and 2-3 at the end. I've got this habit since Bitsler website taught me to many years ago and it kept me safe.
make sure you double-check the wallet address properly before clicking send.
Indeed, the double check is very important. And it's not because one will get transaction error - that would mean that the transaction was not sent -, instead it's because one may send money to address different from what's intended (for example because of clipboard malware).
Also double check would mean that one checks that the recipient address is for the same currency as intended.
One more thing I'd advise the newbies is to play around a little with the wallet of their choice before using it with real money. Electrum for example (if you use it, please download from electrum.org and verify it!) can be used also on testnet blockchain, with testnet coins. One can get some small amount of testnet coins from faucet and play around with electrum. This way he can learn about change addresses, fee, and all the steps needed for a proper transaction.
Even if QR code is used, it is very important to check and recheck the recipient address. If you copy and paste the address, it is still better to check and recheck the recipient address. In this two cases, the recipient address can be absolutely correct, but QR code or Clipboard malware can change the recipient address to a hacker's address. Even hardware wallet users can be a victim of this kind of makware.
To manually input an address can lead to an error or a mistake, and that does not mean the address can not still be changed to a hacker's address with clipboard malware or QR code malware, that is why it is better to check and recheck the address.
Also, it is good to always protect our wallet or out wallet extension from malware, without no malware, this change of address from recipient address to hackers one will not happen, but yet we should check and recheck the address we are sending bitcoin to and do all out best to for security, safety and privacy.

There is no great wisdom or secret here, common sense tells us to check all the parameters of the transaction before pressing the send button. While the coin address to which we send or receive a transaction is perhaps the most important part, things like a change address, transaction size, and fee should not be overlooked either.
I think that hardware wallets play a very big role here because they actually force us to confirm everything that is important before approving the transaction - although this can be a bit problematic on some HW that does not show the entire coin address at once, but in parts - example.

Being your own bank means doing all the necessary work and doublechecking before you click on the 'send' or 'broadcast transaction' button. There really should be no excuse not noticing that the address you intend to send coins to doesn't match with the one the other party gave you especially when the transactions are irreversible. Checking that the destination address is correct is neither difficult nor does it take much of your time. It's just laziness not taking precautions.
I'd say you should copy and paste wherever possible and either check the first and last 5 characters match (after the "1" or "3" for bitcoin) or check the first, last and one middle 3 characters. If you pay more attention to certain parts I think you're more likely to pick up when there's a problem.
