v3l0ct It may be helpful to include the fix for someone in the future.

Here goes (assuming you've installed Vivaldi already, and rebooted Solus):

  1. In Vivaldi, enter the address, "vivaldi:about" in order to find out (or verify) where the browser is installed.
  2. If it hasn't changed in the future, it should be /usr/share/vivaldi-stable.
  3. In a terminal, with su or sudo credentials, change to that location.
  4. You'll find two installers there which both need to be run: update-ffmpg and update-widevine
  5. Execute both of those, and restart Vivaldi. It will now play streaming, such as tv.youtube.com.

I can verify that it works for Netflix and Britbox (here in the USA) as well. The change between widow-size and full-screen runs through a few intermediate states more slowly than on Chrome, so give it a few seconds. But at least it works consistently. I've changed to full-screen and back about 50 times so far, and with Firefox it would have stopped working after the second or third attempt.

    dug Disney+ is a known issue with Linux. Google it and you can get some details.

        v3l0ct Disney+ works now on the latest Firefox update! Thanks to ZachBacon on #Solus-Chat for pointing it out.

          I'm likewise having no problems with Disney+, but I use Vivaldi, not Firefox, for streaming it. I didn't choose Vivaldi because of problems with Disney+, but because I found out that it solved other issues I consistently have with Firefox.

          kyrios This is weird! I have used Firefox and Chrome, with hardware acceleration enabled in both, while the privacy protection in Firefox is set to strict and using Adguard in Chrome, with the end result of Chrome still being faster than Firefox.

              Chrome is known to be faster than Firefox but privacy/freedom/choice is a thing and it's the only serious alternative to blink/webkit engine based browers.

              That's why it is sad imho that there aren't more people supporting Mozilla despite of their sometimes weird decisions.

                kyrios Privacy is less of a issue for me. Firefox can block irritating auto play video's on websites, has tracking protection if I don't want to be distracted by ads and the reading mode is also good. Chrome needs some customization to do all that.

                  The new url to access the bookmarks manager in a tab:
                  chrome://browser/content/places/places.xhtml

                  To open the old about:config interface:
                  chrome://global/content/config.xhtml

                  lekkerlinux Try disabling the hardware acceleration it can slow firefox down and cause other flaky problems.

                    kyrios Alternatively you can also do a sudo rm /usr/lib64/firefox/extensions/lang* and restart Firefox which is less time consuming. : )
                    I need a couple of dictionaries but having them all pre-installed was a pain to use. Make sure to uninstall and re-install any needed dictionary from the addons site in case they got deleted with the command here.

                    The same goes for Thunderbird, simply replace firefox in the path.

                        A little customization of the url bar,

                        To get the url font the same color:
                        browser.urlbar.formatting.enabled true

                        To change the color of the padlock back to green:
                        security.secure_connection_icon_color_gray false

                        To change the color of the bookmark star using css:

                        #star-button[starred] {
    fill-opacity: 1;
    fill: YOUR COLOR HERE !important;
}

                          sangheeta kind sir, do you know how to do this in vivaldi as well? I am getting NO info online except 'we changed to grey and there's nothing you can do with it.'
                          thanks.

                              It depends of the website you visit, some have and some others don't. 😅 I don't find solution either.

                              We can modify urlbar color font using css:

                              /* font color of the urlbar */
#urlbar-input-container {
color: YOUR COLOR HERE !important;
}
