So the problem is that Firefox doesn't play any HTML5 content. Weirdly except for Youtube. Youtube works just fine. But every other Website shows errors. Even songsterr.com. I'm using latest Firefox 76.0.1 on a recent Ubuntu 20. 04 LTS installation. Usual troubleshooting like updates doesnt work because "sudo apt-get upgrade" doesn't find any updates. I tried the same websites in the latest version of Chromium and they work perfectly fine. I couldn't find a mistake in the firefox settings or something so I'm confused. Disabling Plugins didn't change anything and turning of tracking protection didn't either. What is the Problem here and how can I solve it?

There is a fullscreen mode that prints a window over the full size of the screen without showing toolbars/navigation/extensions... Is there a "full window" mode that do the same, but over the full size of a window? It would be a simple webview in a system window but without the control toolbars. It would be very useful when tiling several Firefox windows without wasting space for toolbars/tabs... This mode should be specific for a window since I do not want to loose the controls on the main screen-wide window.

I've been an avid user of Firefox Monitor for the past few months, but recently over the last few days when I go to https://monitor.firefox.com/user/dashboard and log in, I've been struggling to find the button that allows me to add new email addresses. I've searched the support article for Monitor for this information, but to no avail: https://support.mozilla.org/en-US/kb/firefox-monitor. So I was wondering if you could point me in the right direction?

Hi, I have been using Ubuntu Mate, for some time now, since the latest installed versions, Firefox is unable to print the invoices generated by the revenue agencies site. The print is generated empty, it only shows the details of the site and some accessory data at the top. I tried to install an old version, 78, if I remember correctly, and the prints are fine. I tried with another browser and the printouts are correct, again. Does it happen to you too?

Due to printer software I am forced to migrate family laptop from linux mint to windows 10 Both systems use version 82.0 (64bit), firefox just got installed on fresh windows 10 install, I opened it browsed a little to create history files and closed to swap it with linux history/passwords/tabs/bookmarks But in windows 10 firefox seem to have different file structure, and didn't recognize old version Have file structure changed or there are steps I missed or (unlikely) I messed up with file location, main mozilla/firefox folder path is still there

Will online synchronization of firefox just be as good as hard file copy from one system from another? I think this might be easiest, yet not perfect solution

In settings I've found font settings. My default font is DejaVu (Serif, Sans, Mono)

After changing font (type and size) noting is going on. Even after restart. I disabled option to let wep pages set their own font.

The most important thing for me is to have working "Minimal font size".

To sum up. I can change everything in advanced font settings but there is no result on web pages.

This problem occurred Oct 24, 2020 Australian Eastern Daylight Savings Time (3 weeks after daylight savings time came into effect here). The operating system time is correct. I have cleared the cache several times, rebooted and shut down overnight.

A forum site is displaying the correct times. A site displaying weather information uses the correct time; I loaded it just after 3am and the first time it displayed was 6am as expected.

1. A TV guide normally highlights in red programs currently showing; at present it shows programs showing one hour previously. In Google-Chrome no programs are highlighted. I have removed the cookies and that has made no difference. 2. Facebook.com times are one hour late, both the time of posts in the newsfeed and times of notifications.

I am trying to use a program (video display) and when I press the button to allow adobe flash I get a very small long thing and an error that says something like "#error 3409" I have re-installed it. My addons say that I have shockwave flash installed. I have installed adobe flash several times with the same result. Perhaps I should remove shockwave flash and install again. I have no clue.

Thank you................

Why add-ons won't start with Firefox? Every time I need to manually disable and enable extensions Privacy Badger, uBlockOrigin (Privacy out of the box extensions) for it to be working, that is, they don't work upon start up. I have deleted the .mozilla folder in my Linux machine to reset firefox and it starts with add-ons only one time; when starting a second time, add-ons don't appear in the toolbar yet they are "enabled" but not working. As previously stated, I need to enable them manually.
