Firefox Community Forum

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?

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.

Trying to enable NextDNS for DNS over HTTP but it shows as not active (TRR_PARENTAL_CONTROL). I do not have any parental controls enabled on this device so im not sure whats causing this isssue.

I used Chrome until two days ago. I just got tired with how shitty the browser was, how bloated it made my computer, and how much Google treats everyone like a data product. However, I use hella google systems from Voice to Chrome to Drive to more and it all worked great together. Choosing to change to Firefox wasn't an easy decision but I knew it was a good one

Which makes it super irritating that some of the functionality is already facing problems. I have shortcuts I built to make it easier to study or do random things so I don't get distracted or tired. One shortcut is clicking a key that should launch UWorld in my default browser & use Lastpass to autologin (I couldn't get it to launch the service but that was a separate issue).

I check if autologin was on for the password on LastPass I've allowed all permissions to the LastPass extension I clear my cookies on UWorld & turned off enhanced tracking protection for the UWorld login portal site

What should I do to fix my one button shortcut again?

I really don't want to go randomly turning off every protection that Firefox gives me to figure it out so I'd appreciate someone who understands the browser better helping me out. Also, bonus points if you can help me build a single shortcut button on my Mac that can launch UWorld & navigate me straight to the question bank. (I do think the issue with autologin on LastPass is going to become more of an issue as I start opening up more websites I used to use on Chrome so I'd rather nip it in the bud before I see the problem occur more often)

I was reading about CSS custom variables at https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_cascading_variables/Using_CSS_custom_properties, and noticed that the example at "Using @property to control inheritance" does not work as described in the latest Firefox (115.21.0esr, 64-bit. on Windows laptop).

More specifically, both the parent and child divs come our in green, but the child div is supposed to come out in cornflowerblue.

Although it is not affecting me yet (I haven't decided whether to use this particular CSS feature), I was wondering if the issue was known.

I do not know what to do for the best

Until I installed the latest update (136.0.1) I could open Firefox and navigate, never having to log into PW manager until I came to a site where I had to log in and use a saved PW. I have many sites where my login is remembered, and I don't have to log in, so this isn't needed most of the time.

Now EVERY time I open Firefox that request for my primary PW pops up and I have to hit CANCEL twice to clear it before I can to anything. It's an annoying pain in the tush.

How do I turn this off, or set it so that that pops up ONLY when I have to log into a site?

Latest update of Win 10 3/15/25

Thanks.

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 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
