Translation, may not be fully in line with your standard wording. The original message, in Swedish, below.

"When I seek information with Firefox, since some time I always get this error message from AVG: "Threat secured, We prevented your sonnection to thai.rontyig.come since it is adnagerous website. Threat category; URL.Blacklist"

Even when I search for AVG, the same msg is shown. If I use Chrome or AVG Secure browser, there is no error msg.

"När jag söker en uppgift med Firefox får jag sedan en tid alltid upp ett felmeddelande från AVG: ” Hot Säkrat Vi förhindrade din anslutning till thai. rontyig.com eftersom det är en farlig webbsida. Hotkategori: URL:Blacklist ” T,o,m, om jag söker på AVG visas samma spärrmeddelande!

Om jag t.ex. använder Chrome eller AVG Secure browser

Ich wollte die Beihilfestelle beim Landesamt für Finanzen aufrufen. Das ist leider nicht möglich. Könnte es sein, dass es einen Zusammenhang gibt damit , dass ich vor ein paar Tagen ein Antivirusprogramm von Avast heruntergeladen habe, nachdem ich seit Monaten dazu von Avast genötigt wurde, da mein Laptop angeblich schwere Probleme aufweisen würde. Beim Online-Banking hatte ich vor Wochen ein ähnliches Problem (das war allerdings noch vor dem Herunterladen dieses Antivirusprogramms), dass meine Zahlungen nicht verifiziert werden konnten. Nach Kontaktaufnahme mit dem Service der Bank sagte man mir, dass ich einen anderen Browser benutzen solle, da Firefox angeblich Sicherheitslücken aufweisen würde.

Hello,

I have had an issue for a few months now where certain websites fail to load. This is most easily reproduced on https://addons.mozilla.org, where I am shown the error "An unexpected error occurred" on most pages, preventing me from installing addons.

This issue does not occur in a Private Window, in Troubleshooting mode or in Chrome or Brave, but persists in fresh installs of Firefox. In troubleshooting this issue, I have removed all program files, registry data, and app data pertaining to Mozilla / Firefox. In fresh installs, I can sometimes install an add-on or two before this error starts occuring. I have not imported any previous data.

I was previously installing from Chocolatey, but in my last clean install, I downloaded from the official website.

I am on Windows 10 and Firefox 157. I use Proton VPN (Paid) and have tried changing servers several times to no avail. Again, this only happens in Firefox in a standard window, Private Mode and Troubleshooting Mode are fine.

Screenshot 1 shows the issue from my most recent reinstall. I was able to install 1 add-on (SponsorBlock) before it started showing up. Removing the add-on doesn't fix the issue. Trying to access addons.mozilla.org via a search engine results in the tab icon loading for a second and no change happening on screen (Screenshot 2).

I experience similar issues on other websites, like trying to log into Bandcamp.com (logging in gives the error "There was a network error. Please try again."), but most sites work.

Loading https://addons.mozilla.org/en-US/firefox/ gives the following results in the Network Console:

Uncaught (in promise) TypeError: can't access property "pressed", target is null
