Youtube starts in the middle of the screen then moves to the right side with other thumbnails overlapping the left side of the video. This does not happen in any other browsers I use and only started happening in Firefox about 6-8 months ago to the best of my memory. Full screen works fine. I just do not want to watch in full screen all the time.

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot.


If you have made changes to Advanced font settings like increasing the minimum font size then try the default setting "none" in case the current setting is causing problems.

  • Tools > Options > Content : Fonts & Colors > Advanced > Minimum Font Size (none)

Make sure that you allow websites to choose their fonts.

  • Tools > Options > Content : Fonts & Colors > Advanced: [X] "Allow pages to choose their own fonts, instead of my selections above"

It is better not to increase the minimum font size, but to use an extension to set the default page zoom to prevent issues with text not being displayed properly.
