I'm running Firefox 100.0 (64 bit) on windows 10 pro 21H2. I've been using Firefox to access Flightradar24 to view real time flight across the globe. All of a sudden today the map doesn't appear any more . I think they use Google maps and overlay their info.

The maps show properly in MS EDGE and Google Chrome.

I've attached a screen shot of what I get.

Thanks

Secure connection failed and Firefox did not connect Firefox Last updated: 01/16/2024 39% of users voted this helpful

This article explains why you may see a Secure Connection Failed or a Did Not Connect: Potential Security Issue error page, and what you can do.

   If you see a Warning: Potential Security Risk Ahead error page, see What do the security warning codes mean? and How to troubleshoot security error codes on secure websites.
   To troubleshoot other error messages, see Websites don't load - troubleshoot and fix error messages.

   Secure connection cannot be established

Secure connection cannot be established

When a website that requires a secure (HTTPS) connection tries to secure communication with your computer, Firefox cross-checks this attempt to make sure that the website certificate and the connection method are actually secure. If Firefox cannot establish a secure connection, it will display a Secure Connection Failed or Did Not Connect: Potential Security Issue error page. Secure Connection Failed

A Secure Connection Failed error page will include a description of the error and a Try Again button. There is no option to add a security exception to bypass this type of error.

I have used Firefox for years and also use Kaspersky as my security along with Kaspersky's password manager. Recently, after a Firefox upgrade, while using Firefox to access websites using passwords it will not auto fill from Kaspersky. I have the extension installed. Kaspersky works on all other browsers.

Google provides a different key to differentiate installed copies of Google Chrome (standard or "Google Chrome for Work") in this file:

"/Applications/Google Chrome.app/Contents/Info.plist"

Google Chrome:
<key>KSBrandID</key>
<string>GGRM</string>

Google Chrome for Work:
<key>KSBrandID</key>
<string>GGRO</string>

Is there such an identifier on Firefox vs Firefox ESR?

Thanks, Don

I am trying to setup proxy server for Firefox 106.0 on my Windows 11 Laptop. I have Windows 11 setup to provide system proxy settings to a local intranet squid proxy server at port 3128 with a configuration file. With this setup both google chrome and Microsoft Edge find the proxy and correctly utilize it. when I use Firefox and watch the squid logs the proxy is bypassed when settings are set for "use system proxy settings, no proxy, automatic proxy configuration url" If i set to manual proxy configuration it works.

I'm really shocked that the developers at Firefox has not at all fixed the memory leak issue, which caused my PC to crash three times in a row. This is clearly unacceptable; even other browsers I use don't eat up a lot of RAM in a matter of seconds that ends up my PC lagging, or worse, crashing as a result. To the Firefox devs; why are you overlooking an ongoing issue that should've been easily fixed from the get-go, especially with updates that obviously have nothing to do with the memory leak issue? It's really easy to make such a popular browser not hog up memory so easily without causing so much lag, even on higher end PCs.

If the memory leak issue isn't fully resolved by greatly reducing memory usage, especially if I'm only using one or two tabs with me, I will have to consider seeking for another working browser that does not have a memory leak issue, and remove Firefox and never reinstall it altogether.

Dear Firefox Team, good morning.

I hope you are doing well and that you are all healthy.

Guys... while looking for a way to measure the performance of our site, we came across the Core Web Vitals (CWV) some time ago. These are Google KPIs for measuring the user experience on a page (https://web.dev/vitals/#core-web-vitals). Unfortunately, some of the KPIs (like the Largest Contentful Paint or Cumulative Layout Shift) are currently only accessible using Chrome and it's preformance API. That's a pity, because there are also many people using Firefox who visit our site... and it would be interesting to have such KPIs as well.

In an article by Cloudflare (https://developers.cloudflare.com/analytics/web-analytics/understanding-web-analytics/core-web-vitals/) we recently learned that Firefox is also planning to expose the metrics used in the CWV... only the "coming soon" from the article is a bit vague. That's why I'm contacting you to get some more information on that topic. Do you perhaps know whether the topic is planned and will be tackled this year?

Thank you for your attention. Best regards, Carlos

Hey all,

Last night I made the mistake of clicking a sketchy link on twitter thinking what it was some meme site( the person who tweeted is someone I know personally so I thought it was safe) once I clicked on it, I wasn’t redirected to the site so I thought it was weird then once I learned that he deleted it because it was compromised. I got scared and I was running scans through Microsoft defender. After the full scan it said that it detected Trojan:HTML/Phish!pz and the affected files where C:\Users\….\Local\Mozilla\Firefox\Profiles\cq0glqqq.default-release\cache2\entries. I deleted my cache a few hours later than I should.

So I reached out to a friend and they told me that it was probably was a false flag and I didn’t need to delete my cache. But I’m nervous that it’s an actual threat and I should do more to ensure my computer is completely safe. Also probably a lot of grammar mistakes I haven’t slept since I got this information.

Hi there, after turning on my computer in the morning, Firefox has been suddenly rendered utterly inoperable and pulls up a PR_CONNECT_RESET_ERROR for all websites. No matter what I do, including all other fixes previously suggested on the Mozilla forums and elsewhere, nothing seems to work.

Things that I've already tried and did not work include: - Pausing Kaspersky Internet Security - Resetting WiFi router - Switching to a different WiFi - Turning on troubleshooting mode - Resetting Firefox entirely - Creating a new profile - Reinstalling Firefox (several times) - Installing Firefox for Developers - Flushing DNS - Turning off proxy settings

I really don't want to be forced to use Google Chrome. Is there anything else that I can possibly do that can fix this?

When I scroll down the page on MSN and try to open a link in a new tab the page jumps back to the top. It then opens a link of another article that I never right/left click on. I have my mouse set up to left click to open a new tab. Does not occur on any other sites.

It has been doing this for months now.

Website will not allow Firefox to display the page if another site has embedded it

Firefox Can’t Open This Page

To protect your security, rabbitstream.net will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

Okay, I give up. So, Facebook is or has implemented this Turn on two-factor authentication or whatever it is. What this means for me at the moment is that I am unable to access my Facebook account as it is now forcing me to use this Two-factor authentication thingie, despite that I do not have a mobile phone. (yes, I know it's unusual in this day of age not to have one. I did have one at one time, but for the moment I have no interest in getting another one). I would rather use my laptop anyway.

Doesn't Firefox have a Two-factor Authentication thing that I can use with Facebook? Without a mobile phone using the Firefox browser on a computer or laptop?

Now, from what I can see, Facebook is offering 3 ways of doing this. #1) Authentication app, like Google Authenticator or Duo Mobile. #2) Text message (SMS). #3) Security Key. So, because I do not use or have a mobile phone, I was guessing that my option would only be #1 Authentication app, like Google Authenticator ... which I have never used before, and while reading up on it, I keep reading that I can only use it with the Google Chrome browser?!? If that wasn't bad enough, I typically use Microsoft Outlook, not Gmail. So, I am at a loss at this point.

Again, I do not have a mobile phone. Doesn't Firefox have a Two-factor Authentication thing that I can use with Facebook? Without a mobile phone using the Firefox browser on a computer or laptop?

Help please.

Any help to fix this would be much appreciated

I have tried restarting both firefox and my computer, disabled all extensions and started firefox in safe mode. When I try to right click on a firefox window from the taskbar it just disappears.

I have my computer connected to my TV so often when I open it up some windows will be on my TV which is behind my desk so its a pain to move them back without this function.

I'm talking about the built in "AI Overviews" for Google search. When the mouse is anywhere over the search content it provides, the page will not scroll until I move below it, or to the scroll bar.

I just realized it does not occur in Chrome, as far as I can tell. The Chrome search does not show the AI indicator on top.

The best you get is an occasional slight single jumping motion with a mouse wheel scroll anywhere withing the boundaries of that straight line just below the search field, the straight line below "Show More", and the inner border of the scroll bar
