Firefox Support Forum

Since I updated to version 113.0.2 every time I try to open certain websites, Firefox shows an error message "SEC_ERROR_UNKNOWN_ISSUER". Once I choose to accept the risk and continue it redirects to the IP address "79.137.248.81" that redirects to spam. This happens on multiple sites, certain popular sites such as google work perfectly.

Yesterday I uninstalled and installed the browser. I rkilled and scanned my system with Malwarebytes, Avast and HitmanPro. I also have no malicious addons I found. Nothing worked.

I am attaching pictures of how the error shows.

Please Help.

I installed Firefox at work and set my personal email address as secondary to my business address. Well, I liked Firefox so much that I decided to use it at work and at home - and I removed my personal email from my business account. Unfortunately Firefox is still recognizing my personal email as the secondary address for my business account and I am completely incapable of making a new account. My bookmarks and saved passwords are all different between home and work. I NEED two individual accounts, just like how I was using my browsers with Chrome. t

I run Windows 11 on my Laptop. Every few days, Firefox slows down so much that it becomes essentially unusable. If I uninstall and then reinstall, it works fine for a few days, and then it repeats its slow performance. I like Firefox, but if this continues, I will have to switch browswers.

Please help.

Hello,

I use Firefox at work and at home on the family computer. To have the possibility to access business data at home, I created a login for my business browser settings. If I micc now from home with my Firfox business account log in and log out again opens the next time Firefox from home automatically the browser with the start tabs of the business. This also after restarting the PC. I want to avoid this at all costs. How can I make the browser accessible to my family again, so that the usual tabs are displayed at startup and we do not need an extra password for the family browser?

Kind Regards

Frank

From the last week Firefox started to give me the error "Secure Connection Failed" / SEC_ERROR_INADEQUATE_KEY_USAGE, preventing me to access some intranet sites. The first time I tried the "Refresh Firefox" procedure found at the beginning of the dis-installation function (started through the standard "Add or remove programs" Windows 11 interface). Now this error re-appears only for one of the internal sites from time to time. If I close all the browser windows and re-open Firefox, the error changes to "Warning: Potential Security Risk Ahead" / MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT (which is an error I'm expecting since the intranet site is using an intenal Certification Authority that I've not yet put among the trusted ones) and with this message I can now proceed to the site by selecting "Advanced..." and "Accept the Risk and Continue".

Which is the reason for SEC_ERROR_INADEQUATE_KEY_USAGE error? I cannot find a mention for it inside https://support.mozilla.org/en-US/kb/what-does-your-connection-is-not-secure-mean ... Is there a way to debug it? Or to avoid re-occurring and the need to restart Firefox?

Firefox version is "113.0.2 (64-bit)" on Windows 11 (10.0.22621.1702).

Hello

Noticed in the last few days I cannot change the proxy settings. Use to be able to. I am on the latest version of Firefox as of today. Try to run Firefox as an administrator but still greyed out. Not sure what is causing this. This is on Windows 10 and a 11 device. Do not have any GPO for firefox. Any idea how to find out what is causing it or ho wto fix it?

When I log in, refresh, or just open up the website, I'm met with an error message attached below. I use a HP Pavillion Laptop, Windows 11, and am on version 113.0.2 (64-bit). I've tried the following: - Make sure spotify is up to date - Restart my router - Make sure 'Widewine Content Decryption Module provided by Google Inc.' is enabled. - Allow Firefox to play DRM controlled content - Disabled my plugins - Tested this on other browsers (they work) - Made sure I'm not using a VPN. Oddly enough, Spotify's web player seems to function alright in Private mode and the app is fine too. I will try any all solutions presented, please.

I just installed Firefox 2 days ago on a new computer and have no problems till today. I was watching a movie when suddenly all tabs crashed. I have tried uninstalling and reinstalling, checking for malware, making sure firefox was up to date, clearing cache data and history, disabling plugins running troubleshooting mode and restarting my PC. Please help I cannot use Firefox at all.

So a few months ago I was having issues with Firefox so I deleted it. But today I redownloaded it, and it was working fine, but all of my data is gone my passwords bookmarks my history is there anyway to get this back.

Hello - Firefox to Safari bookmark syncing used to work seemlessly between pc and ipad. Noticed it's no longer working. I've done all the resetting/restarting/logging out/uninstalling/reinstalling recommended. It still won't sync. I ended up installing Firefox on the iPad to get the bookmarks from PC. That sync works (takes a while sometimes). But it will not ever update the IOS from the last time it worked (maybe 3 months ago). I can erase IOS bookmarks and reload from iCloud, but the files are months old.

Has this function just been removed?

I have been with FF for years now but I started to notice a few months back that sometimes a web site I want to go to would not load with FF - a blank page would come up. Also, that some sites were very slow to load. I would go to EDGE and the sites pop right up with no problems.

Some examples - StartLogic, VERY slow to load on FF. United Health Care - I bring up the site, put my login info in and it brings up a blank page. I go to EDGE with both of these programs and no problems. There are other sites that I have the same problem with.

What's going on with FF? I would like to keep using it but I am finding more and more sites that act like this.

I go to youtube, open a video and the audio plays just fine, except there is no visual. The video says its playing and I can hear it normally but I can't see anything. Subtitles show up, but the place where the video is supposed to be is just blank, the same as the background of the page. Weirdly if I click the settings button on youtube, the one next to the sign in or account button, the video will display as long as that menu is up. If I close the menu the video goes away.

I have refreshed firefox, deleted and reinstalled firefox, removed all my extensions, turned hardware acceleration off (and then back on when it didn't work) as was recommended in a similar post a few years ago, and restarted my computer. Youtube still won't show me a video. It works fine on chrome, just not firefox.

I uploaded a screenshot of an ad, which doesn't play but shows the outline of the video player, a screenshot of a normal video where the area the video should be in is just more indistinct background, a screenshot of the video appearing normally when I have the settings menu open, and a screenshot of the captions loading properly over an empty void.

Edit: I installed the Enhancer for Youtube extension? Which I haven't ever installed beofre? And now Youtube works? Why

2nd Edit: Its broken again. I changed literally nothing, just restarted my computer for an update but im getting blank screens again

Video download helper is installed but icon is missing from toolbar and cannot be found where I'm told to look when I google the problem (i.e., view/toolbars/customize). Nor can I drag it to the toolbar from where I find it when I look under triple bar/addons and themes in the upper right corner of the toolbar. Where else should I look to find it?

When I open a pdf and close it to a certain page, after reopening, firefox brings me back to page 1 and not to the last page I read. To make it a perfect pdf reader, it would be great to implement the memory of the page in use.

When I try scrolling down on this website it automatically takes me to the top of the webpage like a reset. The hardware is fine because it is happening with touch pad and external mouse both. Even though it is happening only on 1-2 website, I am not sure whether it is my browser's issue or the website itself is faulty. Also, specific part of the URL keeps on refreshing nonstop : ?ref=n2dXHxxxxxxxxxxxxx

The YouTube videos load in troubleshoot mode, so I reopened Firefox and disabled all extensions. That did not help, so I uninstall all extensions. That does not work either. Other browsers work, but Firefox does not.

My issue is a bit difficult to explain. When I downloaded Firefox on a new computer, I signed in using my gmail account email and password. I created many passwords and bookmarks. I wanted to sync my phone and laptop to this account but I already had an account on my laptop. My new computer all of a sudden notified my that my log in was disconnected. I signed back in to my account and now it is only showing my bookmarks and passwords that were on my laptop and not my new computer. I only want the things I have added to my new computer and not what was on the laptop. How to I retrieve the bookmarks and passwords that I had set up prior to Firefox disconnecting me?

os = ubuntu 22.04 - 5.19.0-42-generic Mozilla Firefox 103.0.1 I am attempting to connect to a proxy that does not require a username and password, yet moz-proxy is continually asking for one. If I put any input in the prompts, it goes away, but if the machine is rebooted, the prompts begin again. How do I permanently stop firefox from asking for the username and password?
