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.

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.

The error SEC_ERROR_REVOKED_CERTIFICATE means that the website's SSL/TLS certificate has been revoked by the certificate authority (CA). This prevents secure connections because the certificate is no longer trusted.

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?

An error occurred during a connection to tp.tax.gov.ir. PR_END_OF_FILE_ERROR

I dread the days where FF has an updated version of something for me to install.. because this issue ALWAYS rears its ugly head.

I've been ignoring the updates since Feb and for very good reason because this time (138.01 or whatever) I'm unable to bypass these security certificate expired error codes that say:

"If your clock is already set to the right time, the website is likely misconfigured, and there is nothing you can do to resolve the issue. You can notify the website’s administrator about the problem." I literally was able to access all these sites without issue until I downloaded your must have update. How is this fixed???

Should I just uninstall FF and go back to Brave? I'm so tired of dealing with this as a normal day to day, no coding/tech background, etc. internet user.

Today, out of approximately 31 attempts to connect to Amazon or (once connected to Amazon) navigate to a new Amazon page, Firefox succeeded 14 times. 14 out of 31 is good in baseball, poor in basketball, and unacceptable in connecting and browsing. Here is the "error" according to Firefox:

An error occurred during a connection to www.amazon.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

I have read the potential solutions to this problem. I did disconnect my VPN (Proton) and was able to connect to Amazon on my next attempt. However, that was atypical rather than typical - when I attempted to move from one Amazon page to another Amazon page, the END OF FILE ERROR was the result. Further attempts to reconnect to Amazon have succeeded 3 out of 11 times. Yes, I did close Firefox and reopen it, I am signed in to my Firefox/Mozilla account and I did reboot my laptop. I have yet to try the other solutions because I want to be a good Mozilla client and follow the instructions attached to the error message: "Please contact the website owners to inform them of this problem." I have contacted Amazon and am now waiting to hear back from someone in the Technical Department. I am skeptical that Amazon will be able to resolve this because I doubt that Amazon is to blame (this lack of connectivity has also happened with Google, GMail and a couple other sites that I can't recall at the moment.

To clarify, the received data of supposed questionable authenticity has been my login information on the official Amazon login page and also simply the data from an Amazon product page (bike locks mostly)

For me, this is only a problem with Firefox. It is NOT happening on Bing, and even Chrome is able to connect without the END OF FILE ERROR. I have occasionally encountered other instances where Firefox would not connect me but the other browsers would. Most notably, this happens often when trying to connect my laptop with my phone via Bluetooth and other times when I'm asked to sign in to Google or sign in to my Microsoft account. On those occasions, Firefox demands that I insert my original security key from an external flash drive. I would be glad to do so, but I've never had an original security key on an external flash drive. At those times, I attempt the identical login using Bing (success about 9 out of 10 times) or Chrome (success every time).

I am not a cyber guru and am not even technically gifted with computer technology and internet knowledge. I am self-taught and am mediocre (at best) in these areas, so I'm hoping that the blame for this issue is mine as opposed to Firefox being at fault.

I look forward to any advice, suggestions or resolution to this issue and I thank in advance any who reply.

I am on an HP Probook 650 G2, Windows 10 Pro Build 22H2 (HP states that this laptop cannot be upgraded to 11), Firefox version 137.0 (64-bit), Xfinity WiFi 5G, Arris SB8300 Router/Modem. All are functioning as intended except Firefox.

Be Well

I have used Firefox as my standard browser, but now I cannot go deeper into a site, until I see the Message "The address was not found. The browser was unable to find the host-server to the address given." Nor can I go to next page if I have opened the first page. I have Firefox in a Danish version. How can I enable the browser to continue the search? - My proposal will be to uninstall Firefox from my Android phone and afterwards reinstall it, but I am nervous that this means that I lose the data already stored in Mozilla. I have tried other browsers than Mozila. They are able to search through. I hope you have the optimal solution of my problem. I prefer to browse with Firefox.

Cannot access <https://www.blacks.co.uk/> or any other outdoors website such as Millets ot Go Outdoors. Been going on for a long time now with error message:

"Sorry, we're unable to process your request.

Please try again. If this issue persists, contact us with the following error code:

Trying to open my doctor's patient portal and I get a "Secure connection failed" Page. So I start Google Chrome and the website comes up like a charm. You people NEED TO GET THIS CR*P FIXED soon. As much as I hate to, I will make Chrome my default browser if this stuff continues for much longer.

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?

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.
