Subject: Reset font size without using menus

By accidentally pressing and/or holding one or more keys on my PC, I seem to have shrunk the font size which I need to reset.

When I try to use OPTIONS GENERAL the screen will not scroll down to the FONT setting

Could you please tell me how to reset font size without using the menus?

I've got an old Windows XP computer running version 52.9.0. I'm trying to sign in to Sync (so I can sync with my new Windows 10 computer) but when I try on the old machine I get this error message:

Blocked by Content Security Policy

This page has a content security policy that prevents it from being loaded in this way.

Firefox prevented this page from loading in this way because the page has a content security policy that disallows it.

I've signed in on the new computer, not that it matters.

Is the any way I can connect to Sync?

Hello. I cannot watch videos from invidious.snopyta.org on my laptop with Firefox 52.9.0, because a message that says "No compatible source was found for this media." appears in place of the video player. However, the videos from that website do load correctly on my other PC with the latest Firefox version, and they load correctly on this laptop as well when using Google Chrome. The video found on this site, which I think is a webm, plays correctly.

What video format does invidious.snopyta serve and why can't it be played by Firefox?
