Firefox Community Forum

Attempting to upgrade and recommission an old HP laptop not used in several years. Currently running Firefox Version 41.0.1

Any queries to legitimate websites such as Google or Mozilla, return a "This Connection is Untrusted" display screen. Firefox security settings have been changed to lowest security, and problem persists.

It isn't that Firefox isn't reaching the websites... it's that some security setting recognizing the security certificates (like Mozilla's) is broken... and I can't get past it... even to be able to download a new browser version.

Since the last major update, the title bar is blank. Not missing, blank white. If I use the task bar to shrink and restore it, it appears normally. Sometime in normal use it suddenly appears. A search didn't find anything for me. Any ideas?

I am reaching out with a request regarding the regional availability of my add-on.

I would like to disable access to my add-on for users in Russia. Could you please guide me on how to restrict its availability in this specific region? If there are any settings in the Developer Hub or additional steps I need to take, I would appreciate detailed instructions.

Recently I started using Bit Defender. I have been getting these security messages: Suspicious connection blocked now

Feature: Online Threat Prevention

firefox.exe attempted to establish a connection relying on an expired certificate to updates.tb.ask.com. We blocked the connection to keep your data safe since websites must renew their certificates with a certification authority to stay current, and outdated security certificates represent a risk

Hi 🙂

Many extensions don't work on support.mozilla.org.

For ex, Clippings and Unicodify – Text transformer are very useful to write text. It's annoying not to be able to use them to write in https://support.mozilla.org/en-US/questions/new/thunderbird/form.

Seeing https://old.reddit.com/r/firefox/comments/tyytcy/how_to_get_rid_of_this_extension_restriction/i3vke2p/,

1) Why is support.mozilla.org privileged and can pull out information about visitor's system, while connect.mozilla.org cannot?

2) I see that:

• Copy Link Text works,
• Unicodify – Text transformer is able to read selected text but not to write in forms,
• Clippings is not able to read selected text.

Is there a doc which explains what are the limits of what's allowed for extensions in "internal restricted sites"?

Today, Stephen Weisman Esq., in his Scamicide daily post, wrote: While often the pop-up ads may be legitimate advertisements, in other cases they are created by scammers who lure you into clicking on links and being directed to websites that either convince you to provide personal information that can be used to make you a victim of identity theft or, in a worst case scenario, merely by either clicking on the link or being redirected to another website, you may unwittingly download malware such as ransomware or keystroke logging malware that can steal from your phone or computer sensitive personal information that can be used to access your bank account or make you a victim of identity theft in other ways.

He also wrote that pop-up ads can be blocked but I don't see that option on Firefox Mozilla. Please let me know how to do this.

Thank you.

I cannot find current instructions for changing 'dns over https' default resolver. The only instructions I've found reference 'Settings', 'General', 'Network Settings' and 'Configure Proxy Access to the Internet'.

DNS over https isn't located there with FF 132.

How do I change the default resolver to custom resolver?

Hi there,

I know that many users have hated that Firefox asks for the master password from the beginning, but I would like to find an option for it to request it at the user's discretion.

I'm currently using both Firefox Developer Edition and Firefox ESR in portable versions stored on a USB drive for my work outside of the office or home.

The Developer Edition is synced with my Mozilla account and used on both Windows 10 and Linux systems. Conversely, Firefox ESR, which I use on Windows 7 devices, has synchronization disabled. As a result, with Sync turned off and no sensitive data stored in any Firefox installation, Firefox ESR doesn't prompt me for a master password.

Why do I want Firefox to ask for the master password right from the start, even without any sensitive data saved? It's quite simple: sometimes I'm surrounded by non-techy people and I'd like to give the 'impression' (when they see me using Firefox, because most use 'the other browser') that I'm 'protecting something'. It's also a way to 'intimidate' to some extent (if a password isn't entered, they'll think something won't work properly).

It may sound silly, but it's something that 'the other browser' doesn't offer locally.

Also (and I think it's logical), I find it ironic that having other sensitive data saved in Firefox, like enabled cookies, it doesn't ask for the master password, only when there are saved passwords or forms.

I've seen cites that prove that Mozilla's latest policy updates (thanks for no notice) are now positioning Firefox to sell our data for both ad targeting and AI training purposes. I oppose both, and have no use for Firefox if it joins those already disrespecting and monetizing user privacy in those regards. How do I a) ensure I'm getting the plain language notices of further policy updates, and b) register my dismay with Firefox for this betrayal? While you're coming up with an answer, I'll be discontinuing my monthly support for the Mozilla Foundation. I have HAD IT with the greed people ruining everything.
