Firefox Community Forum

Wenn ich im Suchfeld etwas eingebe, kommt immer dieser Fehlercode und ich müsse mich an den Administrator der Webseite melden. Obwohl ich sämtliche Virenprogramme verwendet habe und den PC mehrmals runter- und wieder raufgefahren habe, kommt immer wieder dieser Fehler.

I have an issue where I will frequently get the error pictured on random sites. This started happening a few years ago at my previous home with my old computer. It got so annoying that I had to switch to Brave browser for a while. I recently moved to a new residence, I have a new computer, and a different ISP and equipment, so I thought I would give Firefox a try again. To my shock, the issue still occurs exactly the same way at the same rate. I would say it is as frequent as 1 in 5 sites that I visit. If I hit the Try Again button 5 or so times, the site will load. The only thing I can think of that is common to the old computer and the new one is my Firefox account. Could there be something in my settings causing this to happen? I remember that I even tried Librewolf before switching to Brave but the issue occurred there as well. Any assistance or tips would be appreciated, I feel like I am going crazy at this point. xD

What is the problem with Firefox? Is it s dangerous un-secure webpage now? Can Firefox still be trusted?

So i was going to go to the forums to whine about the new phone layout (cause it's ugly, less compact and laggy to the point of freezing) but the forums seem to be down rights now.

For the past few months, I've been getting this error and been searching for possible solutions. None of which have worked. I am also not using Kaspersky AV. With this, I'm asking if there's anything else I can do.

Here are the solutions I've tried: 1. Troubleshoot mode / disabling add ons 2. New profile 3. Clearing cache / cookies / dns 4. Changing "DNS over HTTPS" & proxy settings 5. Disabling firewall / AV / VPN 6. Chrome loads the site but I do not want to resort to this. Using developer mode browser does not work either for firefox.

Hi, I am working on an extension which fetches my google calendar events and shows them nicely as graphs and summarizes the events. I need a CLIENT_ID in for getting an access token from google (OAuth2). I got one from my google cloud console but I don't think I should push that to the add-ons site.

I am quite new to this javascript/browser world and don't know where to go from here. It would be great if people can just download my add-on and just use it without providing a client ID and zipping it themselves. I asked this question on stack overflow and they marked it as off-topic :_).

So far I couldn't find any information related to this on the web.

When I try to read my webmail I get this:

Secure Connection Failed An error occurred during a (https) connection to www.nebula.fi. Peer’s Certificate has been revoked. Error code: SEC_ERROR_REVOKED_CERTIFICATE

The same address www.nebula.fi works fine in Edge browser, which claims: Connection is secure. This site has a valid certificate, issued by a trusted authority.

I would prefer using Firefox. Is it somehow possible?

Hello! I started encountering this problem as I updated my OS to windows 11. I had eset nod antivirus, but uninstalling it nothing changed. Tried to change MTU cache size through CMD. Changed different DNSes Tried to disable all protection settings in browser and in windows settings. Deleted all extensions. NOTHING helped except clearing cache of the browser, but this is fixing problem only before first browser restart. Other browser on laptop works normally without any issues.

Hi.

Can't access router gateway since last week

Gives error: Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

Gateway is http only, I can access it fine via Edge and Safari iOS

I tried disabling https-only though it used to work fine before with a saved exception.

Made sure Win10 firewall allows Firefox for private/public

Followed the help link and deleted the previous certificate from the certificate manager, but I can't find anything relevant under the servers tab

I'm at a loss. Many thanks in advance.

What ever happened to Firefox?? I try to search for something and 75% of the time I get error messages! Here is what I constantly get:

What is the problem? I have written about this before and NEVER get a response. Is it really time to just switch browsers? I have noticed when Firefox won't work Microsoft Edge and Chrome works just fine. What is the deal here?

Hardly any webpages load anymore. Constantly getting error message. Do not get those messages with Microsoft Edge or Chrome. Can't search for financial institutions, car part stores or hardly anything anymore. I don't believe Firefox can be trusted anymore. Is their a Data Breech in progress with them? I am tired of seeing:

I had opened a support ticket #447010 with Mozella support and they told me that they can not help me, and sent me here. I am "dead in the water" so to speak. It appears that since Firefox downloaded update 153.0(20260715202819) I have had many issues that appear to be getting worse by the day, and now I cannot open or run my email app. I have not wrote down all the errors (sorry) but here are a couple: 431 Request Header Fields too large, the application is having trouble connecting to the server, unable to load the email from Mozella support. After the update (153.0) my bookmarks have moved to somewhere, the sign on for my email app has changed ( use to click on the firefox icon on the bottom tool bar and the sign in box for optonline.net would be there. I understand that sometimes updates (new and improved) make changes to what users have use to for years. Now is have a browser that is not functional and needs to be corrected, I trust you can help and get this sysem usable again, because right now it is not usable. I presume if and when you respond to me issues it will be at this location and not an email. Please help. Thank you

Hmm. We’re having trouble finding that site.

We can’t connect to the server at fzttlwrt.r.us-east-1.awstrack.me.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)
