I am experiencing an issue where Google.com (other google domains work fine) will not load in Firefox, resulting in an infinite loading loop. Other browsers on the same system (Brave) work fine.

Here are the steps I have already tried:

Reinstalled Firefox completely

Removed Firefox via sudo apt remove --purge firefox -y

Cleared all user profiles and caches: ~/.mozilla/firefox, ~/.cache/mozilla, ~/.config/Mozilla

Reinstalled via Flatpak

Tested network connectivity outside Firefox

curl google.com works correctly

DNS resolution works via getent hosts google.com in the host system

Checked proxy settings

Ensured “No proxy” is selected in Firefox → did not resolve the issue

Tested in Safe Mode (disabling extensions)

Problem persists, so not caused by extensions

Tried disabling IPv6 inside Firefox

network.dns.disableIPv6 set to true → no effect

Cleared DNS cache inside Firefox

about:networking#dns → clicked “Clear DNS Cache” → no effect

Disabled DNS-over-HTTPS (Secure DNS)

about:preferences#privacy → “Use secure DNS” → disabled → no effect

Disabled HTTP/3 (QUIC)

network.http.http3.enabled set to false → no effect

Verified Flatpak network permissions

flatpak info --show-permissions org.mozilla.firefox shows network access allowed

Inside the Flatpak shell:

flatpak run --command=sh org.mozilla.firefox getent hosts google.com

→ returns only IPv6 address: 2800:3f0:4001:839::200e google.com

Suddenly i do not have access to a website and only this. the domain is wetranfer.com Actually i do not have access with any browser. not only mozilla firefox I use the default Microsoft defender but i can't find anything in firewall that blocks access to this site. Any help?

I waited for a long time to do an upgrade to avoid problems. Today finally I decided to upgrade to the latest version of Firefox for my iMac, 147.0.1. Before the upgrade I successfully used with zero issues gemini.google.com/app . Now the website comes up, but regardless what I enter as a question I only get an error message stating "something went wrong". The same website works with no issues (TG) with Safari.

Does anyone else experience the same? Is this a known bug with this version of Firefox? Is there a work around for it? Is the solution just using Safari?

I am taking a course online for my medical job I need to launch a course that it is a training course that the business would come to improve care is trying to trade me through but when I click the website it says we've tried to launch the course but blockers have stopped unable to launch course due toblockers

When I try click to search on a word in Firefox on my iMac, which I've done productively for years, I'm now, without having changed anything about my settings. faced with

Hmm. We’re having trouble finding that site.

We can’t connect to the server at gb.search.yahoo.com.

How can I get rid of this?

I was having an odd issue the other day, that I now solved by comparing the settings on a working Firefox profile with mine.

For some reason, on one of my multiple Firefox profiles a list of web apps wasn't working. Among them were Discord, Miro Board, and Google Pay. I was suspecting that they all had the same issue, but didn't know what it was at that time.

The security settings were the obvious suspect (Ad-blockers, DNS, HTTPS enforcement etc.) because clearly something was being blocked, however nothing helped. The solution was in the Network settings. (See screenshot) I was using Manual proxy settings from the time I messed with I2P networks (or something similar).

I am not sure why having a proxy to localhost (127.0.0.1) on HTTP would somehow cause very specific major apps to stop working, while others keep working fine, but it happened to me anyway.

For anyone in a similar situation, with those particular apps not working, check your proxy settings.

Ubuntu 22.04.5 (kernel 5.15.0-153) Firefox updated from 142 to 143 automatically by snap.

In version 142 and older, html file with image source pointing to local (remote) network image file displays properly.

In version 143, this does not work anymore. I tried changing the image to point to a local computer file and it works.

In verion 143, If the link to the image is typed directly to the address tab in firefox, it works.

Perhaps some config setting need to be changed? Hope somebody can help.

Thanks in advance.

firefox network tab shows NS_ERROR_CONNECTION_REFUSED

Click on bookmarks, the drop-down menu appears, click or move cursor on an entry in the list, the new drop-down-menu of 2nd level appears. If the list contains many entries the 2nd level drop-down menu overrides 1st level. This does not happen with firefox preceding version. Note: attaching a picture because a webm video is not accepted.

The website WSJ has large areas on front page, including the opinion listing, are simply white and not 'there' on the page to click on. I've deleted their cookies without effect, tried turning off all adblockers, shut mac down to reboot, nothing seems to have an effect. This is a recent glitch of only several days, prior performance was great. Thanks!

Dear Sir/Madam, Recently I have been having issues accessing a particular website named asus.com for reasons I am unable to discern I keep receiving an error message each time I attempt to access the site. I keep receiving an error message indicating that the site cannot be reached. It should be noted that I do not have any issues with any other websites. Your assistance in resolving this extremely annoying issue will be greatly appreciated. Best regards, Volney Boswell

I'm building a website from scratch and its going great. I just tried to implement a CSP and it worked except for one small section of my website that allows a user to upload an image and that image is supposed to be displayed back to the user. Anyways long story short the CSP blocked me so I tried to whitelist data: and it still didn't work. defeated I removed the CSP from Nginx to work on it later but when I went to try and test again I get this error. ``` Content-Security-Policy: The page’s settings blocked the loading of a resource (img-src) at data:image/webp;base64,UklGRqbeAABXRUJQV… because it violates the following directive: “default-src 'self'” ``` I have confirmed with Curl and by inspecting the network tab that there is no CSP included in the headers anymore. I have restarted Firefox, created a new Firefox profile, and cleared my cache to the end of time and yet still the error persists. I don't know where or how Firefox is storing website headers but they persists and also apparently work between profiles an implication I'm not going to delve into here. If someone could point me to the file where the headers are stored so I can delete it that would be wonderful.
