I've been trying to watch live sports events on SECN+ through my Hulu subscription, but I'm encountering an error message stating, "The media could not be loaded, either because the server or network failed or because the format is not supported." I discovered that Firefox is blocking the stream, while it works perfectly on Chrome. With the college football season and other sports events approaching, I’m concerned that if this issue persists, I may have to stop using Firefox, which I've relied on for over two decades. Please help me fix this issue at your earliest convenience. Thanks.

Firefox is refusing to open sites I am trying to access from links in my protonmail email account. It is giving me a message saying the sites are potential threats. "pdpwbj.clicks.mlsend.com" is what it tells me is the problem.

This is something I do everyday without issue. It isn't limited to one source of emails/websites - it is all of them.

I have cleared cache and history already. Help please as I need to access these websites for my work and having to go to all the individual websites and then to search for the linked content is taking a lot of time I don't normally use because I can just load using the links.

Thank you

I've added https://x.com as an exception site but it is still blocked.

https://x.com/mozilla doesn't work either

Error message on the page:

"Something went wrong, but don’t fret — let’s give it another shot.

⚠️ Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com"

After 2 days it used to finally load without my doing anything, but not now. I never loads using Firefox.

https://x.com is added as an exception, but obviously ignored.

Tried You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

   hold down the Shift key and left-click the Reload button   

NOPE

Tried: Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings), click the padlock icon (Clear cookies and site data) for the domain in the selected tab.

"Remove the Cookies" for websites that cause problems:

   Settings -> Privacy & Security
   Cookies and Site Data: "Manage Data" 

"Clear the Cache":

   Settings -> Privacy & Security
   Cookies and Site Data -> Clear Data -> [X] Cached Web Content -> Clear

   https://support.mozilla.org/en-US/kb/how-clear-firefox-cache 

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

   switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
   do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

NOPE - lost all my bookmarks, extensions, settings - not going there again thank you

as for:

You can check for issues with Enhanced Tracking Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

   click the shield icon for more detail and possibly disable the protection 

the sheild has a slash thru it saying "enhanced tracking is off for this site" when i put my mouse over it.

Cannot access local address 192.168.1.1 which is the address of the GUI interface to my ISP Gateway settings menu. I need it to be able to make changes to the Gateway settings.

I use to get displayed "Advanced" that allowed me to continue forward to get to an "insecure site", only recently that has not been happening (so I am stuck).

Any suggestions, advice, and/or workarounds are appreciated.

Thanks ~Bill

I recently added the "Display Autoplay" extension. I can't seem to figure out how to get the icon to show in the tool bar. See Attached acreen shot. That's assuming that this extension icon can be added to the tool bar. I look forward to anyone's comments. Thanks

I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

bold textdownloading only produces " .part " files in my downloads directory. I had previously attempted a large file download but error message said it was not completed. Now cannot download anything

Whenever I try to sign into any Google site whether it is Gmail, Google, Youtube. or even signing into a site with a google account like Pinterest I get sent to the google help page taking about clearing cache & cookies. Even from there when i click sign in it just refreshes the page never actually taking me to the sign in page.

I just started getting this error:

Secure Connection Failed An error occurred during a connection to www.newsmax.com.

I cannot find how to make this stop. I will get emails from Newsmax about articles and if there is something I want to read I click on the link in the email. I never had a problem with Firefox not opening the link. This just started and I can not get the link to open. I have Newsmax set up as a home setting. However, after I got the Secure Connection Failed error, I could not open the Newsmax web page even if I typed in www.newsmax.com. I am about to uninstall Firefox and use another browser. Can you please tell me how to fix this?

I use Mozilla Firefox for work. Part of my work requires I use the GlobalProtect VPN client. When I log on to the VPN, everything appears to be fine. The problem arises when I log out of the VPN client, such as needing to switch to a different VPN.

When I log out of the VPN client, Mozilla slows down massively. I get the following errors when trying to access websites.

PR_END_OF_FILE Timeout

I thought it was a DNS issue, but the change I made previously did not prove to be a reliable fix, and I do not actually know the root cause of what is happening. Firefox returns to normal ONLY after a full computer restart. At this point I am considering switching browsers as, despite Firefox's functionality, it is starting to interfere with my work.

I have used other VPNs, such as Fortigate VPN, and not encountered anything like this.

Any advice or guidance would be appreciated.

This issue is happening with every newly installed add-on, but not with add-ons installed on or before Aug 3, 2024. The add-ons are installed via addons.mozilla.org. To rule out the possibility that it's happening only with specific add-ons, I also installed one of the random recommendations on that page, Augmented Steam which has 54,248 users, and it happens with that one as well.

I'll click Enable, but the prompt appears every time I restart Firefox.

What I've tried (with a restart after each attempt):

• Clear the startup cache
• Delete extensions.json
• Delete compatibility.ini
• Via about:config deleted extensions.databaseSchema and extensions.getAddons.databaseSchema
• Excluded Add-ons from syncing

I've noticed the following in extensions.json for each of the recent add-ons after restart:

• syncGUID changes to presumably random new value
• active changes from true to false
• userDisabled changes from false to true
• seen changes from true to false

On using Google search, many times it behaves as if I've done nothing...

Communication between Firefox and their server seems dropped. Press enter/search and... nothing

Or do they* want us to use Chrome?

When I copy something to my clipboard I can paste it into Firefox. Into web pages and also into the URL bar.

But when I copy something in Firefox, it does not go to the clipboard. The clipboard still hast the content which was already there.

Also strange: When I cut text in a textarea, input element or the URL bar, the text is removed. But it is not sent to the clipboard. When I cut and paste, the text I get is what was previously in the clipboard.

What could be the cause? How can I debug this problem?

All of a sudden when I open Firefox a dialogue box from Software Update appears and asks for permission to make changes to my computer-- never happened before. My preferences are set to automatically update and my app list says I have the latest version of Firefox (129.0.1). I've checked Firefox properties and there is nothing selected under compatibility mode (I read on the forum this could cause the pop up). I can’t figure out what changes Firefox’s Software Update wants to make if I already have the latest version (so I always say no). The Firefox update to 129.0.1 was 8/14 but this dialogue box only appeared a few days ago. Is Firefox just not working because it’s not getting the automatic update message sent to maintenance? Do I need to uninstall and reinstall the maintenance program? And if so, how do I do that? (Windows 10)
