Accessing Planefinder.com. Have done so many times. After checking on a flight multiple times today, I acquired a notice that said I was blocked from accessing. Is this a scam? It says I entered a word or phrase that was unacceptable and thus am blocked. I can still use Planefinder on my cell phone. I only enter the plane information that is called for. What is going on?

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.

Whenever I now try open firefox, i get a verification page with old looking captcha visuals that is required to open firefox. Why and how do I remove that.

I get Apple emailed advertisements. When I wished to unsubscribe I am sent to "c.apple.com". Firefox tells me that "We’re having trouble finding that site" and "We can’t connect to the server". I believe this is a valid site. I would like to know if Firefox blocks certain websites. If there are blocked sites what is the procedure to unblock them.

This is the message I get when I try to access Kroger.com. It has always worked before and nothing has changed on my computer. No issues accessing other sites.

You don't have permission to access "http://www.kroger.com/pr/pickup-delivery-savings-4?" on this server.

Here is the site I desperately need to click around on. I can't access more than the homepage via Firefox (laptop), Safari (my laptop and iPhone) or Microsoft Edge (my husband's laptop). For the links on the page, I get an error message every time. And I have disarmed as many cautionary protections as possible. Yet other people seem to be able to use the site like a roller rink.

Ideas?

Thanks.

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

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.

I suddenly can no longer get my Gmail to appear in my Firefox browser. (I CAN get to +use Google.com, but when I try to go to https://mail.google.com/mail/u/0/#inbox", I just get a blank white page.) I did not (to my knowledge) change any settings or have some strange thing happen. Please help!

別のノートパソコンやスマフォではアクセスできるがデスクトップパソコンだけで　https://www.minim.jp/　アクセスできない。他の多くのサイトにはアクセスできる。

今まで利用していたChromeでもEdgeでも10日前にアクセスできなくなったので、試しにFirefoxをインストール、その後、このサイトにアクセスできた。それでhttps://www.minim.jp/に接続するときだけ、Firefoxを利用していた。

しかし、28日アクセスすると「エラーコード: PR_END_OF_FILE_ERROR」が出るようになりアクセスできなくなった。 現在もChromeやEdgeではアクセスできない。
