Firefox 技術支援討論區

I need to know why, for a month now if I install User-Agent Switcher then I can no longer access Whatsapp PC. With the User-Agent Switcher extension installed on FireFox, every time I access Whatsapp PC it asks me to update the Browser and to update it I have to go to restore FireFox and thus restore the Browser. Thanks for the solution

So, I accidentally clicked a link that takes me to a site I have never logged into. Firefox prompts me with 3 userids. One is more or less a throwaway, but two are for sites I want to be secure.

I have disabled the form history in options. I have selected each item and tried either delete or shift-delete. None of these options work.

The site continues to present me with 3 userid options.

I hope this is not a major security threat since I am the only user on this computer and the site is one I have never visited, but it worries me nonetheless that I cannot remove the Firefox suggestions.

I found this looking for help with my question:

I see duplicates in the Devices & apps list

If you see devices listed multiple times (and you're sure that it is the same device) in the Devices & apps list, click the Disconnect button next to that device to remove it.

MY QUESTION: What if I am NOT SURE it is the same device? Thank you

When attempting to access https://signup.gmx.com I get the following error;

The requested URL was rejected. Please consult with your administrator. Your support ID is: < 3522328377538005653>

I contacted GMX and they have been unable to tell me why I can't access their signup page. I had my brother do a test from his home. He's on a different ISP. He is using a VPN, but this worked off VPN too. He is using the same ESR version of Firefox that I am, and he's on the same Windows 10 version I am. Also, he's using the same router I am with the same firmware. He can access the page without issue.

What I've tried;

• ipconfig /flishdns
• Checked my IP address is not blacklisted.
• reboot router
• power cycle NTD
• Run Firefox in safe mode
• Clear all cookies and cache data
• Create a new Firefox profile
• Disable Windows private and public firewall
• Rename hosts file
• Disable all firewalls in the router
• Tried different DNS Servers
• Tried different NICs (My PC has 3)
• Rebooted switches
• Checked PC for viruses/malware
• Tried different PCs in the same household
• Tried a different ISP
• Followed suggestion on https://appuals.com/how-to-fix-the-requested-url-was-rejected-please-consult-with-your-administrator-error-on-windows/ with the exception of "Add to trusted sites" I don't run any Microsoft browsers

I do not get this error for any other site. I've been trying to access this page on and off for about 6 months. It doesn't appear to be a temporary error.

Any ideas what might be causing this? thanks

Is this Mozilla article actually serious? So who gets to decide who should be de-platformed?

Until a couple of weeks ago, Firefox (don't know which version but update is automatic) handled media the way I wanted: videos (e.g. YouTube and other similar sites) did NOT start automatically but after I operated the play control the video started with audio enabled. Then I noticed that on some sites audio was disabled when the video started, so I decided to investigate. After spending HOURS reading all the information, trying out settings described Firefox Support, browsing fora where similar / related issues are discussed, refreshing and - eventually - re-installing Firefox, I just cannot get it to work. Until attempting to get this to work the way it did before, I had NEVER configured autoplay in Firefox options. Not had I EVER configured autoplay for an individual website. So, evidently, I don't understand it. Currently, Firefox 84.0.1 autoplay is set (in options, permissions) to Block audio and video but videos start automatically with audio. No settings for individual websites. What I want is that videos DO NOT start automatically but that audio IS enabled when I start the video. Can anyone advise me how to configure that?

The sample example at given following link not working on Firefox version 84.0.2 (64-bit). Video plaback is not happening. https://mdn-samples.mozilla.org/s/webrtc-capturestill/

Other applications using WebRTC have same issues. Please reply.

My TWO questions concern this web page: https://support.mozilla.org/en-US/kb/how-print-web-pages-firefox

1) The web page mentions a new print menu in Firefox version 82. I have version 84.02 installed. The web page above shows "this improved print menu" under the heading "Print a web page." PLEASE NOTE: the "improved print menu" shown does NOT have a Simplify Page option. That option was on the old print menu. What happened to the Simplify Page option?

2) I have tried the "alternative instructions" shown on the web page above but that alternative does NOT give me the old "Print preview settings" shown. Instead, carefully following the "alternative instructions" gives me the same "improved print menu" mentioned above. Why does following the "alternative instructions" give me the new print menu and not the old print menu (which DOES have the Simplify Page option)?

Thank you.

We are facing an issue with Mozilla Firefox when we try to deliver it via Application Virtualisation where the browser tabs continue to crash. We have tried launching this in safe mode and the issue continues. Is there anything else we can do to troubleshoot this issue? or has anyone else experienced this issue?

We are experiencing a second issue where when we try sequencing Firefox with Adobe Flashplayer via AppV, the published application will not show the flash plugin in the firefox options screen. We can see that flashplayer has successfully installed within the AppV package but it seems to be failing to acknowledge the files in the browser. Has anyone experienced anything similar to this?

Thanks

Hi,

Text in " " is translated to English from Danish. I hope the translation is close enough for you to follow.

I used to: - Right click an image on a website - Chose "Show Image Information" to get to the "Media" tab in the "Page Info" window to download a couple of images from a website. Lately this function is not behaving as it used to do.

Now - Selecting more images from the list in the "Media" tab - Click "Save As" - Chose a download folder - Click "Select Folder" doesn't work at all. Nothing seems to happen, not even an error message appears.

Is this function broken in the newer versions of Firefox, or is it just my installation experiencing this? I'm using Firefox ver. 84.0.2 (64-bit), Windows 8.1, Plugin * Shockwave Flash 32.0 r0

Best Regards Mr. Longgaard
