When I copy or paste in the browser often there are double spaces between words.
It seems like it happened sometime over the last 12 months. Has anyone seen this or know why this is happening?
Example:
“He who receives an idea from me, receives instruction himself without lessening mine; as he who lights his taper at mine, receives light without darkening me.”
- Thomas Jefferson
I copied that text from here and then pasted into another tab on Firefox. I can reproduce it when posting into a new text on Patreon or new post on Twitter.
Second example (from here):
Survivorship bias or survival bias is the logical error of concentrating on the people or things that made it past some selection process and overlooking those that did not, typically because of their lack of visibility. This can lead to false conclusions in several different ways. It is a form of selection bias.
When run a search and add highlighting it looks like this:
I'm running Firefox 59 on Mac OSX.
UPDATE:
I disabled all extensions and copied text in Firefox and then pasted that into Twitter and Patreon sites. The spaces were added.
I then copied the same text while in Safari and pasted that into Twitter and Patreon. There were no extra spaces.
I then copied from Firefox and pasted into other applications no extra spaces but if copying first from Firefox and then paste into Firefox it contains extra spaces.
Below is copying first from Firefox and then second from Safari. Notice the extra spaces are added on the paste event. When pasting from Safari no extra spaces are added. It only happens in Firefox.
