Even though bookmarked sites appear with their favicons, no favicon is displayed for any site in Firefox and the other browsers I use. Even new bookmarks I continue adding continue to display the corresponding favicon, but none next to the website address. .

I've had no problems for years when using PayPal to pay for Ebay items, but suddenly 14/02/2020 the PayPal pop-up window just sits there with the spinning circle. Paying by credit/debit card works fine, but I want the payment to come straight out from my bank account. Followed the simple instructions like disabling AdBlocker and checking Pop-ups are allowed, as given in other answers. Still stuck for a solution, saw elsewhere a reference to user_pref file but that just confused me as I'm not that technically minded. Any help would be gratefully received.

http://www.mybroadbandspeed.co.uk/speedtester/ worked fine yesterday (3rd June 2020) but does not in Firefox today. Works in Opera. I believe I was automatically updated to version 77.0.1 between the working and non working. How do I report this/ get a fix for it?

I have used the Firefox browser for many years and for some reason it now is giving me issues when trying to access my online banking which I have never changed. What can I do. The firefox is up to day because they automatically do it. It was last updated on June 3, 2020. What is now the problem and how do I fix this?

I need help on how to load the following websites

https://branch.io https://mixpanel.com/

Both websites just show up as blank black pages. Not sure if it is my security or firefox. Any help will be appreciated.

Every time I try to log into Xfinity (Comcast) from FireFox, I get the dreaded "username or password is incorrect" response.

I can use the EXACT same username and password and log in easily, via Chrome or Edge. But with Firefox, it does not work. I've cleared cookies and cache. I've tried using a private window. I've tried letting Lastpass fill in the stuff for me, I've tried typing it in myself, and still Xfinity does not recognize me if I'm using FireFox, but it works just fine with any other browser. I am so frustrated.

Couple of days ago I opened the Firefox but I saw it keeps opening all web pages with weird characters, I uninstalled it completely, refresh it on safe mode with no add-ons, I see there is no problem with any other browsers suck as chrome or waterfox and others, this problem is only on Firefox...I removed all cookies and everything but still problem going, I use laptop windows 10 with last updates on it...I tried everything available on web sites but no work...I didn't do any changes in about:config...please help me out with this issue, thanks

I am unable to connect to the following URL https://lakmshaegov01.msha.gov/UserManagement/ChangePassword.aspx. All other browsers seem to work.

I ran an SSL Labs test and it confirms that all tested versions of Firefox fail. I would like to know if anyone can spot something that might allow me to connect by temporarily relaxing the security checks in Firefox for this site.

Hi. I had been able seeing lots my own mp4-video which has been uploaded years ago. Not all,

 -  but some of my videos now show a black window,  -  only able to hear the sound-track

www.birkevang.info/Video/England.mp4 show black window but www.birkevang.info/Video/Portugal.mp4 is ok

(If I download the 'black' video from Birkevang-homepage using FTP - the video is still ok on my own PC.)

Mysterious ! (Someone: Mozilla-Windows-xxx- may be had made an update some days/weeks ago  ??)

I have a website, a typical three column design, with NAV, MAIN and ASIDE elements. A reader view option appears in Firefox, but ironically, only the ads in my ASIDE element show up when I click it.

The MAIN content uses SUMMARY/DETAILS to group things. Personally, I would think this combination would scream reader view content, yet MAIN is ignored entirely. It has some links, but so does my ASIDE (advert) content.

My ads are simple blurbs and links, no pictures, for my own ebooks, and are not served by a third party, so I can see how they could get picked up and I'm fine with that. What puzzles me is why the MAIN content is being ignored.

The site in question is: https://waxphilosophic.sdf.org/erotica/ It is marginally safe for work provided you do not click any of the links. No explicit images.

As a test, I even tried changing the SUMMARY/DETAIL of my "What's New" section to ARTICLE followed by an H2 heading. No change in behavior. https://waxphilosophic.sdf.org/erotica/test.html

The HTML passes the W3 validator. I searched Firefox Help / Stack Exchange. Any suggestions would be greatly appreciated.

I just upgraded to Firefox 77, x64, Windows 10 2004.

Firefox 76 already broke LockWise - https://support.mozilla.org/en-US/questions/1287008

Now Firefox 77 breaks 99% of all websites. (See attached screenshot.) www.example.com www.google.com www.wikipedia.org etc

Somehow, support.mozilla.org works, UNTIL I try to log in.

I've tried incognito mode, safe mode, etc. When I change charset of the page, the text displays differently, but it's still a useless mishmash.

--- BUT --- when I open developer tools, click the HTML request and click the Response tab, the HTML renders correctly there.

I think this is a problem of Firefox, because the login in my oxid shop works under MS Edge.

Anyway, in Firefox I see the login window of oxid but despite entering the correct access data, I do not get into the oxid backend. The login window is always there.

Hello,

One website gives me a failed secure connection:

An error occurred while connecting to www.cdkeypt.pt. PR_END_OF_FILE_ERROR

This error is in Firefox but this site doesn't work in any browser

I restart the pc when it re-enters the desktop if i open the browser before the computer fully starts the site works fine which makes me conclued that something is interfering with it and it most be an update or something because i didn't install anything new, but what? it is only this site that doesn't work all the others are working fine.

I tested opening the site in another pc in my network and it works fine.

I hope someone can help me,

Thanks

After the update to Firefox 77. the site https://www.tdscpc.gov.in/app/login.xhtml does not let you log in as a Taxpayer. If you select the Taxpayer option, it jumps back to the Deductor option. Have tried on multiple PC devices- same problem. It works fine on Edge. It was also working fine on a PC which had Firefox 76, but after it updated to Firefox 77, the problem has come.

Kindly advise
