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 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

For the first time after 10 years, I can no longer access my PNC bank account using Firefox V84.0.2. This problem started just this Sunday Jan 24, 2021. I am using AVG and the Defender firewall. When I try to enter my account PNC tells me that it cannot find the code and tells me to use another browser like Chrome or Internet Explorer which I don't want to do. PNC tell me to contact Firefox as, "It is not their problem." But so far I have found nothing in Firefox to solve the issue whatever is causing it. I need help as I would rather not change browsers.

I have restarted my PC, checked and restarted AVG, checked the troubleshooting program, and reinstalled Firefox, but nothing seems to correct the problem. So where do I go from here?

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 have used/accessed Google Maps for years - so many I can't remember and now today I get this message

We are sorry, but you do not have access to Google Maps. Please contact your Organization Administrator for access.

Is this a FireFox muck up or what?

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!

Every time I ry to use the search function in Google Maps I get, "Server Error, Please try again Later". I have been getting this for a week or more now.

I have reset the computer, cleared the cache...is there something in the setting I need to change?

It works in MS Edge.

Firefox 88.0.1 (64-bit) Win Pro 10.0.19042

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, Firefox search bar is not letting me type search term in it, defaults to address bar. The only way i can search is to put search bar in next to address bar. Has this other search bar been disabled or is it a glitch after the update? If anyone could help that would be awesome.

Cheers

Firefox updated to version 89 last night and since then I cannot properly view certain websites I use regularly such as BBC news and Vimeo (have uploaded pic to show). I have restarted computer, and turned off hardware acceleration and cleared cache and cookies - these don't help. If I start in safe mode it's all fine - I've disabled any extensions and themes and tried again but the problem is still there. All was fine before the update. Not sure what to do next.

Hello there,

So, my issue is that some websites, only on Firefox, are logging me out as soon as I enter my mail + PW.

Those are the right ones for sure, and I tried in Troubleshoot mode to see if the issue persists, and it does.

Hence my request here, did someone encounter the same problem and managed to fix it? If you have any idea about what's worth trying, I'm all ears.

I use the following crossword site:

https://thenewdaily.com.au/puzzles/quiz-crossword/

When I open it with Firefox, including the latest version, the "Help" icons are replaced by mathematical symbols. If I use Microsoft Edge, the Help icons are there.

Any feedback will be appreciated.

Cheers, "Sunbury Bob"
