Diễn đàn hỗ trợ Firefox

I cannot turn on the audio input and the audio output in Discord web application when running Firefox for desktop PC. The advice from Mozilla Support knowledge base regarding how to enable microphone did not help, since there is always no access request from discord.com detected in "Preferences" -> "Privacy & Security" -> "Permissions".

I am using the latest version of Firefox (94.0.1) on Windows 7 SP 1 and Windows 10 20H2. In Discord Support knowledge base the app is claimed to support Firefox version 80+.

• When I try to print a webpage using Firefox, the page enlarges 4x and therefore I only get 1/4 of the webpage on an 8.5 x 11 sheet. If I change my browser to Chrome or IE, it prints correctly. If I scroll to the bottom of the Firefox Print Dialog window and select "Print using system dialog" it also works correctly.
• I have the zoom set to 100 and the Print Dialog paper size set to Letter, It is set to print to page width, I tried it with Scale 100 but it didn't help. I also went to about: config and checked that the paper size and scaling were set to 1.
• The the picture of the Print Preview looks exactly like should be when printed, but when it is sent to the Lexmark S505 printer the size is too large.

Since I print 50-100 individual webpages a week, I cannot use Firefox if this can't be corrected.
