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.

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

Everyone going to the above mentioned website experiences the same annoying reloads. Please add a method to Firefox like IE has that can restrict sites reloading, assuming this doesn't exist already. Thanks

My Firefox version is 86.0 on Mac. OS Version is 11.2.2 Big Sur.

I found that basically all color rendered in Firefox is more vibrant than Safari and Chrome, maybe Firefox doesn't handles color management right and renders sRGB in full P3 color space, lead to a over saturate color for almost every element on webpage.

Hopes firefox can fix this soon, I love the efficiency and privacy features on Firefox, This is the only bit I found a little uncomfortable.

You can test your browser here: https://cameratico.com/tools/web-browser-color-management-test/ if you have a P3 support Mac or Windows.

Dear Community,

I have problem with my Firefox version 86.0 (64-bit). I have Windows 10 20H2 64-bit operating system. Firefox can't load some websites. For example I can load https://allegro.pl/ but I have problem sometimes with this website: https://allegro.pl/myaccount/newpayments_incoming.php

If you go there and use F5 key on keyboard (refresh website) sometimes this can't load. On other browser I don't have this issue. This very frustrated me because I can't work. On Windows 10 1909 on older machine (another computer) I don't have this issue with my firefox (this sam 86.0 version). So this is probably problem only with Windows 10 20H2.

Steps to reproduce:

1) Open new tab and go here: https://allegro.pl/myaccount/newpayments_incoming.php 2) Log in to your account for Allegro website (without account you can't load website) 3) When website loads normally you must refresh this website (F5 key on keyboard) few times (you must be patient, sometimes this can take some time) 4) When website can't load or it's load partly you can see that this stops loading when it try connect to analytics.google.com so I think that it is very strange behavior.

On other browsers on Windows 10 20H2 version this website works without issue. Only with Firefox I have a problem. On Windows 10 1909 version on another machine I can't notice this issue. Also on Ubuntu I don't have any problems with this website with firefox.

Can you fix it? I can't work on my computer with Windows 10 20H2 system. I musted to switch to another browsers (Google Chrome, Microsoft Edge). I contacted with owner of the website but this is not the first problem with Firefox on Windows 10 20H2 so you should fix it. I remember that I had some similar problems on another websites but I don't remember what was address for these websites.

Actual results:

Sometimes I can't load this website on Windows 10 20H2 64-bit: https://allegro.pl/myaccount/newpayments_incoming.php

When website can't load or it's load in a part you can see in the bottom of the browser that this stops when it try connect to analytics.google.com so it is very strange behavior.

This can be not problem only with this website.

Expected results:

I should load this website always: https://allegro.pl/myaccount/newpayments_incoming.php

I hope that you can fix it.

When I use Gmail in my up-to-date Firefox under Windows 10 or Linux and type e.g. "Leser und Leserinnen", then exit the draft and reopen it, "und Leserinnen" is gone. This happens to all tested feminine forms ending with "-innen", even irregular or non-existing ones, if they follow the masculine form and " und " (both preceded and followed by exactly one space). The truncation is case insensitive, and when I type the feminine form first, "innen" will be cut, and " und [masculine]" as well. Turning off auto-correction didn't help. Also, when I send a mail containing such a double form, it arrives correctly, but in my sent mails " und [feminine]" is gone. However, when I then open "forward" or "reply" with repetition of the sent mail, the deleted words are back in place. None of this happens when I use another browser or an E-Mail client or the Gmail app on my phone, nor does it happen with other mail providers, not even when using Firefox. I know this sounds weird, as if there were an automatic "politically incorrect maker". But it is exactly what happens. I wonder if anyone can replicate the phenomenon or - even better, find out why it occurs.

I was recently automatically upgraded to a new version of Firefox (87.0). Now when I right-click on an image "View Image Info" is no longer available. How do I get it back? I'm a webmaster, and this feature is very important to me. Thanks.

I try to access my bank website and when I log in the tab says "Something went wrong" and the page tells me Sorry, we couldn't complete your request Sign in to online banking or our mobile banking app to continue. This started on April 1, 2021 Running Firefox v87.0 (64) on Win 10. All apps are current. Tried resetting Firefox, and clearing cache which didn't work. I can sign-in using Edge. Thanks

Hey! My website Doncaster Taxi Doncaster Taxi is not saving cookies on Firefox. Anyone can help be about that?

Since a few days, when I visit Google Maps, after completely loading the page (roads and buildings shown for a brief moment) the map becomes wholly black with just captions still readable.

Doing the following didn't fix: Restart Firefox. Update Nvidia Drivers (updated yesterday to 466.11, didn't resolve). Disable every add-on and setting default theme. Disable Hardware Acceleration from settings.

THIS temporarily fixed: Entering Firefox Troubleshoot mode.

So I assume the problem is in advanced settings. There are TONS of settings there. Any ideas? I 'd rather not go through a Firefox Refresh losing all site permissions/fine tuning for cookie settings/blocked content for every site made in years. I'm on Firefox 88, Windows 10 64bit ver. 2004, GeForce 950M, Core i7-4720HQ, 16GB RAM.

I put "again" in the title since another question about this is marked as solved for Firefox 68/69. Needless to say, I tried everything from that discussion (such as switching gfx.webrender.all), to no avail for the present issue.

I tried Mozilla VPN but it would never connect. So I uninstalled and cancelled. Then I got a persistent vcruntime140.dll not found error. I uninstalled iTunes and legacy Microsoft Visual Suite apps. Now nothing will load. Not about pages. Not password pages. Not websites. Nothing. Have uninstalled and refreshed Firefox multiple times. Have restarted PC multiple times. Have turned off firewall and virus protection. Nothing works. nothing loads. Thanks for your thoughts!

I haven't installed any new Add-ons for over a year but suddenly today the Telegraph.co.uk website is only displaying images. I disabled all Add-ons, re started FF but that hasn't fixed it. Safari is okay though. Mac 10.11.6 and FF 78.10.1esr Thanks for any tips, can't do without a proper newspaper. Kryters.

Hi! Netflix used to work great in Firefox on my Mac OS X 10.11.6 macbook. Now I've been getting an error message saying "Looks like your browser is no longer supported" when trying to play video on Netflix and it won't play. I noticed that it self-updated a couple times over the last few days but these updates did not solve the problem. I'm hoping that this problem can be fixed so that I can keep watching Netflix on Firefox, as I find Chrome and other browsers are very slow and laggy compared to Firefox. Thanks :)

I have no idea what happened but I've lost the Firefox menu bar and the icons I was using for quick access disappeared

above it assent easy to find a way to contact you for support

Since the upgrade I have not been able to access sites I have used in Firefox for years. All the sites are at shockwave.com, such as https://www.shockwave.com/gamelanding/the-daily-snoop-a-hidden-object-game.jsp. I contacted Shockwave but they have no idea, just telling me to disable my add-ons such as ad blockers. That's no solution because (1) I've always had the same add-ons enabled and (2) the same add-ons do not affect MS Edge.

I attached a screen shot of the page I now see in Firefox and what it should look like.

Does anyone have a suggestion to resolve this issue within Firefox?

Thanks.

This problem appeared today! on PC, not all sites but in a couple of the sites, the text won't show or only some of the texts show.

I disabled my add-ons and cleared all the data(history, cache, and everything) even uninstalled and reinstalled the browser multiple times. I got a good antivirus too and there's no problem there. I can Ctrl+A the page and the text just isn't there(like the picture) or it's just a very small blank space(the links in the text are clickable in the small blank space) I tried the Hardware Acceleration method, the windows clear text method, and the text color method too. zooming in or out makes no difference. most sites have no problem or they're missing a very small amount of text on certain pages not the whole site. all of these sites work perfectly fine in chrome and opera.

is this a problem with a new update or something?

here's an image, all the places I highlighted with red, used to have texts!

Hello, it has been some time now. I'm using Firefox 89 on iMac. Some sites' pages become grey and you don't know what that is until you use another browser and find that it's the accept all cookies question on every site you go. Problem is that sometimes you don't see that button and the page becomes grey, it's somewhere maybe but you can't see it and can't click it. How is that possible? That happens evens if I change the settings in cookies management in security and privacy.

Hello one website is not working properly anymore one firefox 89.0 (64-bit). before never had problems. and it is working fine on other browsers. tried to solve it without the addons extensions. not working either. attached screenshots how it is, and how it should be. thanks for any help

For many years I've been able to do a Google search from Firefox, the result being shown on Google.com and from there I was able to click on Settings in the toolbar beneath the search text box on the page, which displayed a drop down with various options, including Advanced Search, Languages, Search History etc.

However today, clicking on Settings on Google.com takes me to https://www.google.com/preferences instead of displaying the drop down. This would force me to navigate to the advanced search manually, making use of the search from the address bar functionality of Firefox amost useless.

This behaviour is only happening for me in Firefox, with Chrome and Edge both displaying the drop down when clicking on Settings.

The Settings I'm referring to is outlined in the attached image.

I've been using Firefox with Virgin Media's TV Go https://virgintvgo.virginmedia.com/en.html for quite a while without a problem. After the latest update I got the message to update the browser to the latest version and restart. I've tried talking to Virgin about it but been given the runaround by them - surprise. I've tried other browsers, Safari, Chrome, but the quality of the stream is poor compared to what I was getting with Firefox. Has anyone got any ideas? Any hopes?

Thanks
