Sometimes you want to copy-paste text from a web page, but it won't work. Here are a few common reasons and workarounds.
1. The text is embedded in a link
The text might be contained by a link. If you click+drag to select text, you will move the link element! Sometimes it is not visible that the text you're trying to select is, in fact, a link.
Solution: hold the ALT key while selecting (Option key on Mac). This will allow you to select text in a clickable area like a button
2. Selecting is intentionally disabled on the site
Click on the μBlock icon to scripts for the site
Reload the page
Copy/pasting is now possible.
PS: μBloc Origin is a versatile, lightweight and open-source ad-blocker. It is probably better than other adblock plugins you might have installed.
