I started Firefox in headless mode, now I want to share that screen with other Peer over WebRTC. This is a demo page of share screen that I use https://www.webrtc-experiment.com/Pluginfree-Screen-Sharing/

When I click the button, this dialog show up: https://i.imgur.com/TdMg6Ki.png

How can I allow the share screen automatically, Firefox don't even allow remember choice. I run Firefox inside a Xvfb session, is there anyway to accept the share screen automatically ( config, run with hidden flag ) or programmatically ?


Thank you

If I open a website with Firefox then close browser and go to open another site on my desktop, Firefox says " Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window". If I hit the close tab, the new site opens. I cannot find any other instances of Firefox running when it says this. Other browsers, Chrome etc. do not exhibit this behaviour. Any ideas ?

Today Firefox disabled most of my add-ons and extensions. Roboform was the most important that I need to get back immediately. I could not log into Firefox to get help because my passwords are saved in Roboform. I could not fill forms online because Roboform does it for me. I have been using Firefox for years and am extremely unhappy. I use Windows 10, Comcast internet, Norton Security Suite, Firefox 66.0.3. [email removed]

The question is simple. I knew there is an update for the users with "studies" enabled. But where is the manual update for the users with "studies" disabled? I have checked the installer download page, and Help -> About. No any update for this. No any instruction for users with "studies" disabled.

I updated firefox and i am guessing the settings defaulted IDK... but when i try to print labels from etsy or any selling plantform they do not open up in a new tab. instead, they open on the same page so I have to always use the "Go Back Page" button which is annoying. Previously I was just able to purchase the label and it would either download to my desktop or open in a new tab. But that doesnt happen anymore. Someone please help.

Thanks in advance

After downloading the latest FF version, I attempt to install, but system dialog tells me that I need to close existing FF process before installing. I've been using Google Chrome. I did use FF about six months ago, but not since.

Ran across a help guide describing process of creating a new profile http://forums.mozillazine.org/viewtopic.php?f=38&t=3025219. I can now ONLY access the FF browser by searching for and running from system bar "firefox.exe -p".

Running Windows 7 64-bit at present.

New system icon for program in menu doesn't permit me to run normally, nor does running as administrator. Would appreciate some help. FYI is a work computer, so I don't want to do anything extreme, as it might cause me to lose data.

Firefox storing cookies and site data even in private mode. How do I stop this?

After the latest update Firefox stores cookies and site data even in always private and the content blocking set to custom with everything set it the highest settings. Example i can check my email at outlook com then sign out click forget, then close the browser. then open it and it loads my email account without signing in. The only way it can do that is, the browser is storing cookies and site data. the only way to prevent it from doing this is to do everything i described then open the privacy settings and clear cookies, and site data and clear history, two times. Firefox like this is the most unsecured browser. it was a lot better before all these changes. It was a good idea, but it's caused a lot of troubles with security issues for me.

When I have 2 or more tabs open and try to go back and forth the tabs web pages close down and have to download the site info. Why don't the sites info stay up in the tab so I can go back and forth without having to wait each time I go back to a tab site. This makes researching very painful.

Is it possible to change the size of the "Flexible Space" when "CustomizingFirefox".

I dragged it to the space just left of the address bar and would like to make the space between the two icons (the home button and back button) a bit smaller.
