Hello Firefox Community,

I'm experiencing a strange issue with my website, https://www.hostgrap.com.

When I visit the site using Firefox, I get the following error:

Bad gateway Error code 502 Visit cloudflare.com for more information. 2025-05-14 04:02:47 UTC

Browser: Working Cloudflare: Working Host: Error

However, the same website works perfectly fine on other browsers like Chrome, Edge, and Safari.

Troubleshooting steps I’ve tried in Firefox:

Cleared cache and cookies Disabled all extensions Cleared DNS and HTTP cache via about:networking Checked proxy settings (set to system default) Tried Private Window Flushed system DNS Updated Firefox to the latest version

None of the above resolved the issue. The error appears consistently only in Firefox. I’m using Cloudflare for DNS and reverse proxy, and the server is working as expected for all other users/browsers.

Additional Info:

OS: Windows 10 Home Single Language Firefox Version: 138.0.3

This issue happens even after disabling all add-ons

No custom rules in Cloudflare specifically targeting Firefox or its user agent

Is there something Firefox-specific that could be triggering this behavior with Cloudflare or my server?

Thanks in advance!

In daily work tasks, I end up with a large number of windows and tabs open. I am wondering if this is not adding to my extremely slow recovery of frozen tabs and windows and MANY instances of "Non-Responsive" everyday. Firefox is set to allow multiple processes, naturally, but I'm looking for ways to ease the pain here. If I disable Multiple Processes in Firefox v138.0.1, will I have problems running, for example, 5 windows with a total of 30 tabs spread across those Windows? (God knows I don't wanna have to grow up and actually manage the things I open up for stuff.) In addition, I am running Canva, sometimes Paint 3D, and Office 2021 concurrently. An associated question........in this most recent Firefox, how do I run Multiple processes, but limit the number of them to 5, for example? There used to be a setting in Firefox to do that, but I can't find it. I'm working with Windows 11-v24H2 on a Dell Inspiron 17 with an Intel Core i7-8550U CPU (about 7 years old) and 16Gb of Ram.........and sometimes I fall asleep waiting for many tabs, windows, and instances of Office 2021 to come back to work (I'm thinking they signed a Union deal, and didn't tell me about it.).

This has been going on and getting progressively worse for about 3-4 months.

Advice? Suggestions? I'd be truly grateful for any ideas you got.

Be descriptive. Saying “playing video on YouTube is always choppy” will help us understand the issue better than saying “something is wrong” or “the app is broken”.

For unknown reasons I cannot load ATT mail or Myatt. I have turned off virus protection and adblock, same result. Not sure when this started. Windows 11 Home. Dell XPS desktop, i9,

I am experiencing an issue with the Keeper browser extension on Mozilla Firefox. Despite configuring all related settings appropriately, the extension consistently locks out every time I close the browser.

To troubleshoot, I have:

Verified that the extension is enabled and fully allowed in Firefox’s Extension settings.

Ensured that Keeper is whitelisted in every possible relevant setting within the browser.

Checked that the "stay logged in" or persistent session options are correctly set within Keeper’s own configuration.

Confirmed that no conflicting privacy settings or third-party add-ons are interfering with the extension's functionality.

Despite these measures, the extension does not retain its logged-in state upon browser closure. This behavior suggests a persistent session issue not aligned with the user-side configuration.

I would appreciate guidance on how to resolve this.

My Mac shut down unexpectedly. Upon rebooting the newest version of Firefox - 138.0.1 was installed. All of my bookmarks have disappeared. I tried to restore from a backup but when I hit restore in the manage bookmarks window it says "choose file" but it lists no files to choose from. I found multiple backup files by accessing my Firefox profile via finder. However when I try to open them with Firefox it displays a blank page and nothing in the bookmarks tab. Is it possible that the bookmark files have also been deleted from the backups as well? If not, how do I transfer these files to the active bookmark tab in the menu bar other than using the restore function which offers no files to choose from?

Why am I receiving repeated warnings from Malwarebytes about blocking every-day websites due to a "Trojan"? The sites include Gmail, Ancestry.com, Newspapers.com and others.

The report warnings are being generated by the Malwarebytes program on my PC. They are confusing to me. I am running Windows 11. The warnings are being logged by the Malwarebytes program in the "Web Protection" section of its "Detection History" web page. In every instance, the log reports are the same: in the URL identification column there is no identification of the URL, only repeated instances of "N/A"; the IP address is identical for all the warnings; the port is always "0"; the file column alternates from "C:\Program Files\Mozilla\Mozilla VPN\Mozilla VPN.exe" to "System" and back again to "C:\Program Files\Mozilla\Mozilla VPN\Mozilla VPN.exe"; in the final column of the log, the Date column, the warnings began last evening, Monday the 12th, at 6:50 p.m. and have now extended to to a total nine warnings.

Even as I was writing this communication, the Malwarebytes warning popped up on my screen, telling me that this website and this web page are blocked due to the presence of a Trojan.

Is my PC infected? The Malwarebytes "scan" reports no "detections." I am at a loss.
