You don't indicate what or where this certificate is coming from for any forum user to know what is happening or why it's not being recognized by the browser.

right click menu copy not clickable,cant copy but when I hit ctrl + c and copy something first then i can copy within the right menu fine with the same site, and no this is not a site issue chromium works just fine.

When I open FIrefox it opens briefly maximized, then reverts to minimized, then returns to maximized. I'd like it to open maximized, period.

When I close my sessions there is only a maximized window open. There are no minimized windows open.

How to do I change this behavior?

Hi all,

Apple has revised/updated their iCloud web portal. The backspace key no longer registers in the iCloud Calendar app on the web. This is specific to Firefox on Windows - I've tried other web browsers to access iCloud web portal and Chrome's backspace key registers so its not an Apple iCloud problem, just Firefox. Is there a setting or do I have to wait for an update?

Thanks in advance.

Hi, Since latest update, loading a video damn slow, few minuted or maybe more to load a video, when I copy the link and open in edge, it very fast, thus, this is mozilla problem, not youtube. Please check the screenshot as per attached. Thank you.

I'm really surprised and frustrated that I can't do this on Windows 10.

Already posted about it here. https://community.spiceworks.com/topic/2492770-start-firefox-private-window-from-command-line-with-2-tab-urls?page=1#entry-10415889

Running 116.0.3.

To repeat, in trying to connect to J. Lawson site for sending cards I received a message regarding cookies being cancelled through the browser I am using. As I stated above, I am 88 and have very limited knowledge regarding the computer. I wouldn't have a clue to cancel anything. This has never happened before. Could this be the result of Norton trying to update my "drivers"? Thank you for the help and thank you for fixing this. I do not want cookies deleted or whatever you folks call it. .

Hello.. I turn on my laptop, start firefox and all my bookmarks are gone... I wasnt log in for very long time during using firefox and what I can do now to get back my VERY IMPORTANT bookmarks?

When I am using Firefox I am no longer having anything on the taskbar to open my Emails. How do I do this? I cannot open emails in order to put back on taskbar.

A new version of Firefox was installed yesterday and now my Adblocker Ultimate is blocking content on some sites. For example, I can no longer see my local digital newspaper and photos on the Eddie Bauer website no longer load. If I turn adblocker off, the website loads correctly. These sites, and others, have worked fine for years. How can I fix this without turning adblocker off?

I was trying to download audio from some of my private youtube videos, but they saved as mp4 files. This did not happen on my phone so I decided to download everything there and send them to my PC using discord, but when trying to download what I could now see was .mp4 it still saved as mp4. If it's of any use the service I used to ripp the sound was mp3juices.

I opened up my browser and all my active tabs which I have had for months are gone. I tried to go to recently closed tabs in history and it doesn't allow me to open. All are not available. Help!!

1 particular https website does not open on my desktop- just a blank screen - no 404. The site is working as I can open it on my Laptop (firefox) and it opens on my desktop in Edge. Any ideas. Worried it may be subject to a virus etc. It's the only site that does not respond
