Can't connect with the just downloaded version 66.0.4 to virtually any site - not to Google, not to NYT, not even to Mozilla - Firefox won't accept ANY certificate! Following errors appear (examples): "Did Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to addons.cdn.mozilla.net because this web site requires a secure connection. What can you do about it? addons.cdn.mozilla.net has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site. The issue is most likely with the web site, and there is nothing you can do to resolve it. If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the web site’s administrator about the problem.

Or: Warning: Potential Security Risk Ahead Firefox detected a potential security threat and did not continue to www.nytimes.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. What can you do about it? The issue is most likely with the web site, and there is nothing you can do to resolve it. If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the web site’s administrator about the problem.

The explanation is as follows: Someone could be trying to impersonate the site and you should not continue. Web sites prove their identity via certificates. Firefox does not trust www.nytimes.com because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates. Error code: SEC_ERROR_UNKNOWN_ISSUER

No problems whatever with other browsers. I'm sending this with Safari.

There appears to be a bug in Firefox when I use this website, https://www.ourguide.com.au/tv_guide.php?r=melbourne&w=now

When you scroll down, the headings move right and show above the wrong information, see attached screen shots.

If you use this website on Chrome, you don't get the scroll issue so I think it is either a Firefox bug or something that needs changing in my Firefox settings.

I am running Firefox 77.0.1 (64-bit).

Any help would be appreciated, thanks.

I've used Firefox forever, however in the last couple weeks, I can no longer use eBay as the webiste looks weird and my account is inaccessible. (See attachment.)

I've cleared all history/caches/etc. per forum suggestions. No change. So now to use eBay, I have to switch to Safari or Chrome (which I rarely use.)

Using new 2020 Macbook Pro and latest Firefox 80.0 update. Any suggestions would be greatly appreciated!

Honestly, I have no idea how to describe it. I loved how when I played a video on Firefox, it wouldn't pop up with that annoying video title whenever I changed my volume. Now, when I'm watching a video or playing audio, this happens. And, it doesn't even get it right most of the time! Like for example, it does this instead! That's not even the page I'm on!

Is there any way for me to get rid of this? Thanks

Hi

For two days I've been searching on the web and in here with no luck.

Initially as Facebook is loading ... I can see the video for a brief second, then its turns grey with the message "Sorry, we're having trouble with playing this video."

Appears to only be a problem on Facebook and only in FF (chrome facebook videos work fine)

Using

FF 81.0 (64-Bit) Windows 10 Version 2004

Tried with all addon's disabled. Tried with anti virus disabled

Tried adding "Flash Video Player for Facebook" addon

Videos all work and play in chrome.

Hi, I faced the problem with Youtube recommendations on a video page. When I watch a video I can't see recommendations, comments and video title (see the image). In console i get an error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://googleads.g.doubleclick.net/pagead/id. (Reason: CORS request did not succeed).

I am on arch linux system.

I've tried to: 1. Update all ca-certificate* packages 2. Disable and delete ad-block 3. Use another browser (there is no problem, only in firefox)

This problem is only actual on Youtube for me.

Today I got what I've seen described as the "Facebook White Screen of Death". I've tried: Reload Clear Facebook cookies (which implies logging back in) Clear site data Restart in Safe Mode None of these things make any difference. Still get only a white screen. Facebook works fine in the Chrome browser and in the Android app, so it must be a Firefox-specific issue, in my case. This is Firefox 81.0.2 under Ubuntu 20.04 The problem only started today. I've used Facebook with Firefox for years without problem.

This problem occurred Oct 24, 2020 Australian Eastern Daylight Savings Time (3 weeks after daylight savings time came into effect here). The operating system time is correct. I have cleared the cache several times, rebooted and shut down overnight.

A forum site is displaying the correct times. A site displaying weather information uses the correct time; I loaded it just after 3am and the first time it displayed was 6am as expected.

1. A TV guide normally highlights in red programs currently showing; at present it shows programs showing one hour previously. In Google-Chrome no programs are highlighted. I have removed the cookies and that has made no difference. 2. Facebook.com times are one hour late, both the time of posts in the newsfeed and times of notifications.

Several days ago I've noticed that YouTube navigation menu on the left started to disappear. See pic-1. It may apper after several tries to open it in other tabs, but all in all mostly not visible. The second and the biggest problem - I can't log out from YouTube. See Pic-2.

I fully deleted Firefox, created new clean profile without any add-on etc, and tried to log in to YouTube - it didn't help. So I think it's not needed to mention all other basic things like cookie deleting etc were done. Problem is always here.

Gmail will not load in Firefox, but will in Chrome. I've cleared my history, cookies, and cache. I made sure I had the latest Firefox update, restarted my computer, checked in internet connection, everything I could think of. There is no error message; it just stops loading and the page is totally blank, as you can see on the attached image. I've run out of ideas and know-how. Anyone else had this issue and resolved it?

SEC_ERROR_UNKNOWN_ISSUER for Google and Youtube

I am getting a certification issue when trying to visit 2 specific sites which are some of the most visited sites in the web: https://www.google.com and https://www.youtube.com

The error it shows when trying to visit these 2 pages, is SEC_ERROR_UNKNOWN_ISSUER.

I have tried to troubleshoot it and follow the solutions recommended at: https://support.mozilla.org/en-US/kb/error-codes-secure-websites#w_the-error-occurs-on-multiple-secure-sites

however none of the solutions described in this guide worked to solve my problem.

In that guide, one of the suggested solutions is to scan my system for any malware. I used the following: Windows Defender Maleware Bytes AntiMalware Karpersky TDSSkiller however the results are all clean.

In the guide, it suggested that I check the clock as well. The system clock however is synchronized.

Last, I have resetted Firefox Profile but this didnt fix the issue either.

I shall note that the issue appeared yesterday and so far nothing helped fixing it. Not even the system restarts.

The issue about visiting these two sites, is limited only to Firefox.

I can access https://www.google.com and https://www.youtube.com without problems using Google Chrome and the Opera Browser.

Also, Google Mail and Google Translate work fine on Firefox. These two sites can be accessed with Firefox without causing any SEC_ERROR_UNKNOWN_ISSUER errors.
