Mozilla's issue, as the Chrome is working perfect.

Certificate Dropa Sep 20, 2023, 8:55:35 AM

You don't indicate what or where this certificate is coming from for any forum user to know what is happening or why it's not being recognized by the browser.

I started getting screen flashes and then identifying pop up windows that go to adform dot com addresses, that are blocked on my computer so nothing other than a error shows up. Its annoying and random. I have checked security page and it says Block pop-up windows and this is blocked. Two exemptions are there which are acceptable. I have run virus checks on Bitdefender and Malwarebytes (Latest versions update) nothing is reported. - What is causing this and how do I stop it? After opening up the hidden window that flashes it tries different pages all fail then eventually the pop up window closes on its own.

Using latest version of Firefox browser 117.0.1 (64 bit) Don't get the pop ups on Google Chrome.

I tried to connect to a website and I received the message in the subject. I have been connecting to that web site for months on Firefox with no trouble. I connected without problems using Firefox just yesterday. After the Firefox problem, I connected without problems to the same web address using Microsoft Edge. I don't understand why Firefox suddenly has this problem.

I don't use McAfee. I recently downloaded Adobe Reader and it appears it comes with. How do I get rid of these constant pop up messages that appear to come from "Mozilla Firefox"?

hi

As title，it's unable to remove check mark in use of primary password. and not able to disable the primary password. could you please help it out? thanks.

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?

Hi,

I noticed that in the last update, Firefox displays the list of login information options, in auto-fill mode, in alphabetical order and not according to the most appropriate address. For example, I get an authentication window for articles vpn.xyz. The first alternative I get is related to the address teach.abc (which does not fit at all) while the alternative for the address vpn.xyz appears in sixth place.

Thanks

I don't know how to turn the ad blocker off. The only thing I can think of that might be part of this problem is the f-secure system that is provided by Spectrum. I use Windows 11 and Firefox117.0.1 (64-bit).

I don't get any security from the master password or primary password because I set it on my mozila browser but when I open mozila, the browser asks to enter the password if you cancel, also I can visit my Facebook and personal mail id. actually, I used two browsers for personal use, I prefer to use mozila only for my primary passport but now it's not worthy .

When I try to reply to an email I get the following message:

Sending of the message failed. An error occurred while sending mail.

Please check your SMTP settings. AUP#OUT-1500

I am able to initiate email messages find. I just can't reply to them.

Hello,

I am writing to inform you about the issue. If the problems with the security certificates that I have had with the browser for the last ten days continue, I will have to delete the application. Thank you for understanding

Regards,

Goran

Really do Like Firefox/Mozilla; Appreciate the opportunity offered to apply an app to link to cell phone; However my Cell Phone does Not allow apps, No Internet Connection. Should I go to 'Settings' to opt-out for the app??

I have a verizon.net email account which I access with Tbird. I had to change all my passwords for security reasons today, and now I can't get AOL to generate a new password for Tbird, so I can't log into the server. My account is a POP3. Help!!!

Hello. I cannot remove the suggestions that appear in the drop down address bar suggestions list. Shift-delete does not work. Changing the search settings in tools does not work. There is no three dots that appear next to the URL, or a pop up that shows up if I hover over the link. They are stubbornly embedded on that bar and refuse to leave.

The only thing that works is to delete all history, but I don't want to do that. There may be some solution where I micromanage site permissions on a site by site basis but that's way too much work, and should not have to do that.

The URLs on the list themselves are totally random. I cannot figure out how Firefox decided that THESE are the URLs to feature. I visited like once, in a long string of activity.

Anyway, my inability to perform a simple task like right-click-delete or demand that it "stop doing that" is making me claustrophobic.

Vers 115.0.2

I am told to disable pop-up blockers in order to have a payment verified. I do not know what pop-up blockers are, I do not know where they are. When I go to Settings and search for pop-up blockers, I am told "Sorry! There are no results in Settings for "pop-up blockers"; and instructed to visit Firefox Support. I have been sent on this circular quest three times now. Please help me.

I have popup blocker enabled.

I am now getting these popup ads from sites I visit.

I have spent 2 hours so far trying to turn this off.

This is driving me mental.

The reason I use firefox is to NOT GET ADS

Especially popup ones that give themselves priority over whatever else is on the screen.

I cannot find a setting to disable this. It's a new thing last few months.

Look forward to a solution or I'll fix it myself by uninstalling firefox.

so i want to delete bookmarks, passwords, cookies, site history, everything!!!

I tried uninstalling and reinstalling but somehow it didnt remove my passwords (and no i didnt enable sync after reinstall)

Reason: I have just spent a good amount of time cleaning up old passwords that i dont use anymore or have changed and not been updated from some reason. When i re-enable sync, I dont want the saved passwords from my phone to resync to my PC. To be absolutely sure that this doesnt happen i would like to just resync all the data to my phone from my sync account.
