Firefox 技術支援討論區

I don't know if this is a system wide iOS issue or something specific to Firefox, but I'm not able to disable link preview when long pressing a link. I was able to disable it in Safari which also disabled it in iMessage, but link previews are still showing up in Firefox and Firefox Focus. It's very surprising for a browser focused on privacy and security. I should not have to make a connection to another server in order to see the URL behind a link. Automatically downloading from an unknown URL opens my device up to zero day exploits and privacy violations. Does anyone know how to disable this completely or submit a bug report to Firefox?

We have a number of websites that are accessible with a client certificate.

We have a user where with one of the websites, Firefox point blank refuses to ask for or supply the end user's client certificate. With no client certificate, they are not allowed access.

Other websites requiring the same client certificate from this user work fine.

We suspect the end user pressed cancel on the "select your client certificate" popup, but we can't be sure.

How is it possible to completely reset the remembered state of a website, so that Firefox forgets any past interactions, and will ask to choose the client certificate again from scratch?

Something in the last few Firefox updates is now preventing me from logging into the admin interface of my home router (Sonicwall TZ570) and wifi access point controller (Unify Cloud Key). I have had these devices for several years and Firefox has always allowed me to make an exception and connect to the "unsecure device. Microsoft Edge is giving me the same problem which started about the same time a couple of weeks ago. I am on the latest version of Windows 10 64bit and Firefox is up to date. The Brave browser still works as it should (see first screenshot), but Firefox gives me the "we could not verify the certificate: reason = untrusted" error with no way around it (see second screenshot). I do not have HTTPS Only Mode enabled (see last screenshot) and I don't see any other security setting that should affect this.

This is my home, not a business and I do not have a domain nor a SSL certificate and I should not need one.

Any help will be greatly appreciated. Thanks!
