Tracking Protection

I recently encountered an issue when attempting to login to The Coventry Building Society website using Firefox (desktop PC & Windows 10):- https://www.coventrybuildingsociety.co.uk/ It failed to display the page used to enter the one time passcode used for two factor authentication.

After looking on some forums I discovered this is because 'Strict' tracking protection was enabled. If I change to 'Custom' and uncheck 'Tracking Content' then things work as expected.

I also read on a forum that you can leave tracking protection set to 'Strict' but enter the URL for the problem website under 'Enhanced Tracking Protection -> Manage Exceptions'. I tried entering 'https://www.coventrybuildingsociety.co.uk/' Initially this appeared to work. However, when I tried it again the following day, the page failed to load as before. I had to change back from 'Strict' to 'Custom' and uncheck 'Tracking Content' once again. It's as if the exception URL is ignored in 'Strict' mode.

Am I doing something wrong or is this how it is supposed to work? Do I need to click on the shield icon (to the left of the padlock icon) and turn off 'Enhanced Tracking Protection' every time I visit the website?

Several of my financial accounts give me this error with Firefox. I had to go to Edge to get my tax documents. I'd much rather have a way to get to my sites without leaving Firefox.

HSTS required

Other websites may require HTTP Strict Transport Security (HSTS) and will not allow access with an insecure connection.

I am trying to log into the indian evisa (indianvisaonline.gov.in) website to print off an ETA (Electronic Travel Authorisation) and when logging into the site I am getting a warning saying potential security risk ahead


Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to indianvisaonline.gov.in. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

The issue is most likely with the web site, and there is nothing you can do to resolve it.

If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the web site’s administrator about the problem.

I do not know what to do for the best

Exceptions for DNS over HTTPS (DoH) do not work

Hello to all,

I wanted to use DoH (dnsforge.de) under “maximum protection”, but with one exception: I would like Ecosia.org to be able to place ads for me, because I am convinced of Ecosia and want to support this project. Tested this with Cloudflare as well, setting up an exception here does not work either.

Now the exception set in Firefox has no effect. It should not be due to the DNS provider, because Ecosia.org is not blocked and has even been whitelisted.

What is the expected behavior of the “maximum protection” setting?

Kind regards

I am trying to login to email service tuta.com. Due to malicious actors, the site is being blocked by Firefox when it should NOT be. Malicious actors have made false reports to create a DDOS on Tuta. When I try to connect to the site I get this message: "Did Not Connect: Potential Security Issue"

How do I tell Firefox to stop blocking this site as there is NOT a security issue.

I'm running the latest version of Firefox on Win 11 64 bit.

In looking through settings, I noticed that DNS over HTTPS, which is set to the Cloudflare default, is inactive and giving the error (NS_ERROR_NET_INTERRUPT). Using NextDNS is fine.

The problem is not unique to FF, as another Chrome-based browser has the same problem, and I have switched that to OpenDNS.

I have been through all the possible causes and diagnostics for Cloudflare not working (firewall, running FF in safe mode etc.) but can't see anything.

However, I did download the Cloudflare desktop application, and when this is running in background, the Cloudflare DNS/HTTPS settings work perfectly in both FF and the other browser.

Whilst I can of course keep using the other DNS providers, I'd prefer Cloudflare, but I don't really want to have yet another app running and consuming resources, which would be the case with Cloudflare.

If anyone has any suggestions for why Cloudflare isn't working, or how to fix it, I'd welcome them. I have searched high and low for more information, both here and elsewhere, but if such exists, I haven't found it.

Hello,

I just did a full windows defender scan and it turns out Trojan:Script/Wacatac.H!ml popped up when it was done and it said the files affected were:

containerfile: C:\Users\User\AppData\Local\Mozilla\Firefox\Profiles\.default-release\cache2\entries\InsertHashHere

file: C:\Users\User\AppData\Local\Mozilla\Firefox\Profiles\.default-release\cache2\entries\InsertHashHere->(GZip)

I removed the hashes or whatever they were behind the entries, I was wondering if this was a false positive? I didn't notice any slowed down or hacked accounts, also windows defender quarantined it. I've also reinstalled Firefox and deleted all folders associated with Mozilla in AppData.
