Curious behaviour with YouTube Posts. Linux Mint 23 Virginia
Currently Running Firefox 158.0(64-bit)mint-001 - 1.0 Linux Mint 21.3. This actually started with 157. This peculiar to the System Package version ONLY. The versions on Flatpak Mint, Windoze, iOS or Android have the problem.
In brief, If the text in a Youtube post exceeds approximately 150 characters, excluding the dots(periods), when the preview is clicked on then the post itself only shows that text and the expected "Read more" is missing. What is visible are three dots in what appears to be a far smaller font thus making me believe the link to the script that does the reveal has been suppressed.
Unless there is something hidden in about:config to cure this there doesn't seem to be any way around this.
Ideas would be welcome
