I-Firefox Community Forum

I have just re-installed MW due to probs using the original one, but now I cannot enter my registration code,(life time) there is no where to do so it seems,have looked everywhere?

I keep getting '500 error' when trying to login to my Evergy account. The Evergy support was helpful so I could use Google Chrome however I would like to use my Firefox browser. They had me clear browser history, cookies and other site data and cached images and files. Then restart the Google Chrome browser. How can I get the same data cleared in Firefox?

I have used the privacy and security settings in Firefox and cleared cache and history and cookies, but still can't log into my account.

This has been an issue since 12/01/2024

Recently when I try to access any of my accounts on my Mobile Phone through Firefox I get an error that says This Website Requires A Secure Connection. I don't get this message from any other browser on my Mobile Phone and I don't get this message on my Desktop. It tells me to try again or go to the Advance Tab and it still does not go to a site.

The bookmarks and everything works except to take me to a website.

I am getting this message on my desktop from a site that I was using for a few years without any problem. Must to be something in my computer because my roommate in his computer is able to connect to this site. Need help to fix this issue.

"Hmm. We’re having trouble finding that site. We can’t connect to the server at unsoloclic.info. 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)"

on using firefox for first time, get message

The connection has timed out

The server at www.google.co.uk is taking too long to respond.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

on re-try, problem disappears using 136.0 Beta 5 last daily update 12 Feb 2025

error message:

Hi!

After asking from an customized Al at https://huggingface.co/spaces/hd-hg/First_agent_template, I tried to take a screenshot of it's error message but the screenshot taken is white. If I tried to take a screenshot with the built-in Linux Ubuntu 22.04 LTS "Take a screenshot" tool, the screenshot included the content that I wanted to screenshot. I am attaching these two screenshots for reference.

Also Outlook told me that screenshots@mozilla.org does not exist but it is listed as a available source in about:support page in Firefox browser.

I am using the compilation ID 20250211160552. No snap, the official one from the repository.

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.

Why does Firefox intermittently fail to connect to the Newsmax website? I get a Secure Connection Failed message. It happens only occasionally, but enough to be an annoyance. What's the problem and how do I resolve it?

Greetings all, my trusty Firefox stopped working. Error Code PR_Connect_reset_error. Other browsers work fine. I have windows 10 with the latest updates and use Kaspersky Internet Security 21.3.10.391 (m). I have paused Kaspersky, uninstalled then reinstalled Firefox 3 times. I have cleared all Firefox cookies and caches a number of times. On my 2nd Firefox reinstallation Firefox worked ok for a couple of times then stopped again with the same error code. Please note that I am not very familiar with computer stuff so any suggestions need baby steps. Many thanks.

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.

So I'm getting the reset error code on only my twitch and YouTube tabs, now I have no add ons, I tried the cert9 file thing and that didn't work. I tried resetting my cache and that does not work for me, the issue is it's only for those 2 websites, everything else works just fine. I have tried a different profile that didn't work, I tried resetting Firefox and that didn't work, I tried resetting the router that also didn't work at all. I tried the troubleshooting firefox and same result, I'm in the original firefox, or rather not the troubleshoot one. I also tried signing out of my firefox account, that also did not work, and so I'm stuck on how I can get back my tabs that arent opening. Also I did try opening them as new tabs but they didnt work as well.

Every time I try to get on Discourd I get a message that says An error occurred during a connection to discord.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

I am using standard tracking protection, i checked Don’t enable HTTPS-Only Mode, i cleared cookies, nothing work.

I have never had a problem opening my email client before in Firefox, but now after the last time I started my computer I get this message when I try to open my email client (Shaw Webmail):

400 Bad Request Request Header Or Cookie Too Large nginx/1.24.0

Oddly though, it will open if I go into the Incognito window. Why is this happening and how can I fix it so I don't have to constantly into Incognito mode to access it?
