Firefox Support Forum

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
• Read through this: https://support.mozilla.org/en-US/questions/1197304

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

Hi, Since 1 week i can't use all the fonctionalities of Google photos. I can't download albums, i can't share, i don't have infos about pics of album, etc... All the icons at top right are inoperatives. I've tried another browser (Google chrome) and all is fine. I use Windows 8.1 and Firefox 73.0.1 64 bits Regards

Trying to request a demo from bigcommerce.com. It complains javascript is not enabled. ("Please enable javascript and try again" about:config shows javascript.enabled = true.

What I've tried: 1. Disabled all addons / extensions 1 by 1 until they were all disabled. 2. Turned off tracking protection 3. Turned off content blocking. 4. Set all group policies to "not configured" (Had only disabled off telemetry and update any way). 5. Set network settings to "no proxy". 6. Cleared cache 7. Removed all bigcommerce.com cookies. 8. Reset all permissions (location, camera, notifications etc).

If I restart with add ons disabled it works fine, yet I'd disabled all add ons. The only preferences I had disabled were related to telemetry (in about:config).

The second time I lost all my data(200 tabs, bookmark panel, pws, addons). My steps: 1. Sync all data into 1 firefox account from 1 device 2. Reinstall my OS on the same device. 3. Connecting back by logging in and pressing the sync button and... Blah! I see nothing. No synced tabs, no bookmark panel. At the same time I did this kinda operation with having connected 1 account to 2 virtual devices(1 - real OS, 2 - Virtualbox). So could you please explain how Firefox Sync works? Is there a way to use sync account as a keeper for tabs and bookmark panel without using 2 devices? Or other ways? Thanks!

Whenever I look in my history and click on a website it immediately moves to the top because Firefox only remembers the most recent visit. I want a proper history that shows all visits with well structured time. How can I do this? Is there any good addon?

Awesome Partner takes thousands of bird pics. I store then on Google drive. How can I delete them from Downloads? Is there a bulk delete command? I'm using Firefox on a Linux computer.

thx.

I found multiple pages recently that cause problems with the network monitor in firefox developer tools. I attached an image as an example. The three requests are selected always as a "block". They seem to be somehow related but I do not find any documentation what their relation is. My educated guess (also see https://superuser.com/questions/1537396/what-is-the-reason-firefox-combines-multiple-requests-in-the-network-monitor) that it is HTTP/2 related. However I still do not get how to handle debugging in such circumstances. I'd like to see the individual requests and answers for debugging purposes. I do not find a way to reach that goal. Is it a technical restriction?

My addons/extensions disappear when I reboot my MACBOOK . I have installed DuckDuckGo, ADBlocker, Capitalone and some others. However, when I restart my computer the next day all of my addons/extensions are no longer there. I have reinstalled at least 3 times and with the sme result. Please Help ! Thanks
