Firefox supportforum

My website is www.santiagoroutes.nl, the subdomain is mobiel.santiagoroutes.nl The certificate is valid for both (see certificate as shown by Firefox in attached picture). The website is marked safe by Firefox, and also by Google Chrome and Microsoft Edge). The subdomain is marked safe by Google Chrome and Microsoft Edge, but Firefox marks it unsafe, and if you click Show commection details and More info you get "Verified: Not specified". Then, if you click View Certificate you see the same certificate you see when you started from the main domain.

What goes wrong?

What did Mozilla do recently to screw up Firefox?

On some websites (e.g., https://www.usbank.com/index.html and https://www.penfed.org/) which I commonly visit, I suddenly start getting error messages when I try to log in ("Your username and/or password are incorrect. Please try again." on the U.S. Bank website and just "FAIL" on the PenFed Credit Union website). I can log into both without any problems using the Chrome browser (which I don't like using). I have called both U.S. Bank's and PenFed's website support departments (having spent over an hour talking to each one) and both claim that there's nothing wrong with their servers, websites, or web pages, but instead lay the blame on FireFox; I'm starting to believe this, since I can log into my accounts using Chrome without any problems. This problem just started (for me) two days ago. And yes, I cleared all of my history, and I also shut down and re-started Firefox.

So, with this background, What did Mozilla do recently to screw up Firefox?

For the last couple of days I have been having trouble with my Garagesale ebay listings. The images will not download when I start a Garagesale listing. The problem is specific to Firefox, as the same listings display correctly on Safari, with all images in place. Is there a security or other preference that might stop the images loading from the Garagesale server? I also get an error message when trying to access some other pages on the garagesale website (see attached image). Any help or possible solutions would be very welcome. I've tried all the usual cache emptying, refresh Firefox, restarts, etc, without any luck.

Thanks in advance.

Running Firefox on Ubuntu 20.04, Windows 10, and Android 11. versions 83.0, 83.0, and 83.1.0 respectively.

As of 12/10/2020 discovered that on Ubuntu 20.04 Firefox would not get to cdc.gov and gave message "server not found".

On 12/11/2020 I started digging a bit deeper.

• Firefox on the Ubuntu and Windows hosts, both on home WiFi (Optimum, public IP 24.47.128.216) does not get to cdc.gov with message "server not found".

• Firefox on Android 11 (WiFi connected and LTE at 3 bars) does connect to cdc.gov. Don't know how to tell if connection via WiFi or LTE.

• Firefox on Ubuntu and Windows hosts using USB tethering to phone for Internet does not connect to cdc.gov.

• Chrome 87.0.4280.88 and Chromium 87.0.4280.88 on Ubuntu and Windows hosts on home WiFi connect to cdc.gov

• Edge 87.0.664.60 on Windows host on home WiFi connects to cdc.gov

Seems Firefox desktop for Ubuntu and Windows is having some kind of problem with cdc.gov. Have tried running in Safe Mode and selecting Restart with add ons disabled and Refresh Firefox. Neither option has resolved problem.

What's wrong?

Whenever I try to logon to a specific financial institution in Firefox I am taken directly to a "password change required" page even though I have a valid password already setup. In MS Edge, however, I have no such issue -- I get right in and can do my online business with them. I'm not using "Private Window" for this attempted logon.

I have been trying all day to access the Centers for Disease Control website at cdc.gov. Firefox (83.0/Mac) just says it can't contact the server. I used Network Utility to look up the IP address of the site, which reported 198.246.102.49. I entered that address into Firefox and it refused to go there, saying it was a potential security risk.

So I tried Safari (14.0.1), and cdc.gov loads immediately with no problems.

What the heck?

At present I cannot login to by Bank Website. When I enter my user name & password, I get the following error - Error: 1007 ID: 18.77b0f748.1607801677.a17cbfa - It was fine a few days ago, but since yesterday I have this problem. I can still login using another browser, so this must be a Firefox issue. Any help would be appreciated.

Very often form input fields don't show up when using Firefox, both on Windows and Android. When that happens I have to visit the same website on Chrome or Edge to fill out forms. See these screenshots and link to illustrate the issue. Thanks for any advice.

The website in question is Pastebin (https://pastebin.com/). Momentarily, I thought the website was down as I checked multiple sites (like downforeveryoneorjustme.com) and they shared the conclusion that it was indeed down. However, most of my friends claim the website is still up and running. Is this an issue that I can fix, or perhaps something out of my reach?

I am trying to stream from a French website (M6) for which I have an account. Specifically https://www.6play.fr/kaamelott-p_888/la-vie-est-belle-c_11364952 I get as far as locating the programme (see link above) I want to see but then I receive "An AdBlocker is preventing access - please close it etc...." I tried creating a new profile in Firefox with the same result. I do not have this problem with other sites and am not aware of having set up a Blocker anyway. (That isn't say I haven't by accident). Where do I look please? I am using 83.0 (64-bit). On my machine I also have Edge and Chrome because some sites seem to prefer these. In fact Edge is the default browser because (guess what) some Win10 functions work better with it. The same message comes up using these browsers so I am thinking it might be a Win10 setting but I cannot spot any setting that is relevant. Any guidance you can give greatly appreciated.

I am running an old computer using XP. All I want to do on this computer is view Virtual Railfan live streaming videos. When I try to view a video, it says that my browser doesn't recognize any of the video formats available. Then it points me to a html5 faq. When I click on that I go to Firefox home page and it wants me to download Firefox. I already have downloaded the latest Firefox. Is there a workaround for this?

Hi, I'm searching an answer to my problem but, please sorry, I don't find it.

On some webpages, there is an 'internal' viewer for the images (or thumbnails).

With a pre-version of Firefox Quantum, on this webpage, for example, if you click on the images at the bottom of the page, the old FF showed the image with a internal viewer like in the attached image.

On the current Firefox, it asks me to view the image with the standard Windows imageviewer (or save it). Where is the option to open such images in the webpage iteself? TIA.

Trying to log in to spectrum > e-mail. Log-in to spectrum is fine. Link on that page loads the basic frame and links for the webmail page but the e-mail content does not load, where it should be is just white space, and the links in the frame do not work. This happens with chrome as well, on my desktop (win10) and on my laptop (Win7). I don't use the webmail often and so do not know when this might have started to be a problem - but it has not always been a problem.

The webmail page loads well with Edge.

Firefox is my main browser, don't use Chrome much. FF is up to date. Popup blocker for those pages is disabled.

What's going on?

how can I force my browser to redirect links that point to www.amazon.com to actually go to smile.amazon.com? I'm not wanting to BLOCK amazon, just enter through the proper access. most links are put into emails/documents as www.amazon.com and I want my browser to default/redirect to smile.amazon.com. if I can figure this out, I can also use this for other sites which support non-profits for traffic/transactions.

firefox won't load any pages of etsy.com for approximately the last two days.

although the site's logo appears on the browser tab, the browser window itself is a blank white page, no error message, no spinning wheel, and the full webpage address showing in the address bar.

help.etsy.com loads fine, although in reality, that directs to a zendesk domain.

etsy.com loads fine on other browsers and isn't showing outages on down detector, etc.

i have cleared the cache, cookies, etc., closed and reopened the browser, made sure i'm using the latest version, ran a malware scan, made sure there are no permissions, rules, add ons, apps, or other things that are interfering with the site loading.

i have not changed any of my firefox settings in the last year, besides automatic updates. antivirus also up to date and i don't appear to have any malware.

any ideas?

(also providing this info to etsy.com, in case the issue is 100% on their end.)

thanks in advance for any insights.

On page https://support.mozilla.org/en-US/kb/html5-audio-and-video-firefox?redirectslug=viewing-html5-audio-and-video&redirectlocale=en-US

I find "AAC and H.264/MPEG-4 AVC are patented audio/video compression formats. They can be viewed in Firefox using built-in OS libraries (so neither Mozilla nor you need to pay a fee) if embedded in the MP4 container format (.mp4, .m4a, .m4p, .m4b, .m4r, .m4v file types)."

But when I create an HTML page with the following HTML5 code:

<!DOCTYPE html>
<html>
<body>
</body>
This is a test of video.
<video src="C:/MyVideoFile.mp4" controls>
</video>
</html>

I get the error "No video with supported format and MIME type found". Does Firefox in fact support .mp4 video? If so, what changes do I need to make in the HTML?
