Firefox Community Forum

Hi All, I want to block traffic on firefox externally for managed devices via Intune, following the import of the ADMX/ADML files into intune.

I have set '\Mozilla\Firefox\Exceptions to blocked websites' to the following

• //*.mydomain.com/*

which works, however, I also want to add hosts that are only resolving on IPs and not DNS. I can add specific IPs if known, but is there a way I can allow IP ranges? Ie

• //10.10.*/* (this doesn't currently work)

Of the included screenshot, only the wildcard for mydomain.com and the specific IP currently work

If there is a better way to do this via intune for firefox only, please let me know.

Thanks

Hi,

We are using Mozilla's URL (https://firefox.settings.services.mozilla.com/v1/buckets/blocklists/collections/certificates/records) to fetch the OneCRL.json that contain the list of CRL data. This URL was working fine till recently (last month) and we see this URL is returning 404 error. Attached the screenshot of the error.

Need some help on this. Is this a temporary issue OR Can we use different Mozilla URL to get the OneCRL.json data ?

Appreciate any assistance on this.

Thanks, Bharath

Hello. I know how to define a server certificate exception to avoid browser warnings in case of certificate issue with a website (see attachment). However, I'd like to apply that exception for all users with access to my machine using a GPO (for user or local machine). This is also a requirement in my work where many users run Firefox from a server and the face browser warnings all the time (related to self-signed certificates) so it would be great to apply an exception for all users through a GPO specifying the self-signed certificate warning we want Firefox to ignore. Thanks.

I have been using my email for years and suddenly today this message came up and I cannot access my email because an error message came up. i accessed earlier today and then this message. I use my provider as my home page and it has never been an issue before. The only thing I have changed is I downloaded a codec update. I can still receive emails from this address on my phone. I can still access all the sites I visit except my webmail.This is the full message: An error occurred during a connection to webmail.westnet.com.au. Peer’s Certificate has been revoked.

Seit ich meinen neuen Computer habe, kann ich mich bei meiner Commerzbank nicht mehr mit Benutzername und Passwort anmelden. Ich werde immer wieder aufgefordert den Benutzernamen und das Passwort wieder einzugeben, was immer zum gleichen Ergebnis führt. Denselben Vorgang kann ich aber mit meinem alte Computer problemlos durchführen. Beim neuen Computer klappt es aber auch nicht mit einem anderen Internetprovider, etwa Safari.

Hi : We are planning out server farm capacity, network gear needed, for a new site for our AI micro-services. We are curious when do you think that Firefox will support TLS 1.4 ? and will the overhead/utilization difference be between TLS 1.4 and 1.3 which we currently use exclusively. I understand that we are talking servers, and FireFox is a browser, but we cant dig up any real-world stats on the workload difference between the two. Any help would be appreciated.

Thank you for your time Albert Baker.

I have recently received a notice from Mozilla informing me that the Security Certificate for Firefox is set to expire, and if I do not update it, Firefox may develop issues and stop functioning. As I am not very tech savy, and do not understand the language, I do not know igf/how this will affect my system. It is set to update automatically. I have included a screenshot of the notice below. I keep the system simple, and do not use add-ons, etc. Can someone please explain what all this means in laymans terms?

Hi,

I saw some forums and even google is blocked and i have this problems. I paste here the problem but my browser is en french:

I have always used Firefox to log in to my Tesco Bank account, but for the past few days I am getting this message that Access is denied on this server, yet I can log in OK from other browsers. I am based in the UK.

I use a laptop, Windows 10, have done disk clean up, removed cookies & cache - all the usual stuff, but still get the same message. All other websites are working fine, any ideas why I am not allowed to go into my Tesco Bank account when using Firefox?

Any help much appreciated.
