I get the following error when trying to connect to my bank. It worked fine yesterday and didn't perform any updates or make any browser changes. If I go into troubleshoot mode, I don't encounter this issue. I have no issues on a different computer. How do i fix this?

Thanks

I had a hard drive error - was a loose jumper but had to reinstall firefox on windows 10 machine were FF was working as designed.

Now, Firefox will not work - see below for error. I have searched and watched videos and nothing is working. All other browsers work fine on the same PC. Only Firefox cannot get to internet and when FF is closed after a short while I get a FF crashed error. If I try and restart FF before the crash error a pop says FF is still running. Any ideas?

ERROR MESSAGE:

The connection has timed out

The server at amazon.com 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.

Getting an 'Error 429' screen when I try to open www.realestate.com.au - which I use regularly so quite odd to receive this message. Not same issue if using Chrome, Edge, etc, so appears to be just Firefox issue?

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 don't know if this is generated by FireFox or the software I am using:

"Image generation failed with the following error: The prompt could not be submitted. Your current safety filter threshold prohibited one or more words in this prompt. If you think this was an error, send feedback."

Working on some cartoons and entered this:

"large old GREAT HORNED OWL wearing large pince nez eye glasses"

....And that note was generated. What the heck???

Trying to search on Firefox is now 70% impossible. Keep getting error code: Secure Connection Failed

"An error occurred during a connection to www.google.com. PR_CONNECT_RESET_ERROR

What is going on with this? I even get this code when I try to search on how to reset ALL settings back to factory default. What can be done??

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

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:

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?

When I get this error: An error occurred during a connection to appliedmagnets.com. SSL received a record that exceeded the maximum permissible length.

HOW am I supposed to contact the website to tell them about that problem if I cannot get on the website to get their contact information? (phone and/or email)

Hi, I can't login to a website with FF although it works with Brave and FF Klar on my smartphone. I cleared the cache, deleted the history, restarted FF and the laptop, tried private mode, and disabled privacy settings as much as possible. There are no extensions installed/loaded. The password and user name is correct ;). Pls help! Thank you!

I have never has this happen. What is the problem and how do I fix it?

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

I keep getting this when I click on a highlited site I believe is an ad search and so I can't access that specific site. What do I need to do to access the site?

Hmm. We’re having trouble finding that site.

We can’t connect to the server at ad.doubleclick.net.

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)
