Firefox Support Forum

I've been using Firefox for a week now and every time I work on my clients WordPress websites they show this message after a few hours of working on them:

"Secure Connection Failed

An error occurred during a connection to 4everyoung.com.br. PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

When this message appears I need to restart my computer for the website to load again, when I use the websites on Chrome they don't show this error but if this error appears on Firefox, the website also stops loading on Chrome until I restart my computer. I've realized that activating and deactivating plugins will make this error appear but sometimes I'm just working on the website normally. This doesn't happen on any other websites, only my clients websites that I manage. All of them use WordPress but some are hosted by Hostgator and others are hosted by Hostinger. I've followed the steps of every forum post out there about this issue, contacted my hosting providers and they have no idea as to what may be causing this issue.

‘When i am on ebay after 4 or 5 selections everything locks up only way to free it is up is close Firefox browser then I'm unable to launch fire fox for several minutes sometimes have to do restart of pc!. Only site happens on. I asked ebay they didn't help completely unable to shop. Please help! I'm retired rocket Scientist go figure! Bruce Allen

For some time now FF will not open certain sites that it used to, these sites all open and function normally in other browsers such as Opera. The most important being my online bank! I have contacted the sites involved and they cannot understand why. I have cleared Cache, cookies etc. I'm using FF 88.0 on Ubuntu. Can you help?

To be honest I do not know whether it is talking about the website or Firefox in general. I can use Firefox on all other websites in different tabs. I can use the Bank website using either Chrome (at work) or Edge (at home), but I do not want to have to use Edge if I can help it. I have deleted all cookies and data on this computer and that did not do any good.

Please help!!

This problem is a combo of the site and the browser. Here is a page of the site that misbehaves: https://www.yucatan.com.mx/merida/2022/6/13/detienen-en-merida-profugo-de-la-justicia-en-estados-unidos-326494.html (and attached) Most pages on the site do not misbehave. The problem is that the body text is all jammed to the right side of the screen. I have tried clearing the Firefox cache, and sometimes that works, I have tried restarting in troubleshooting mode, but that does not change anything. Internet Explorer shows the same problem, but the Edge browser does not display the problem. I suspect the site is doing something funky that results in a problem on some pages for some browsers. That's really hard to troubleshoot!

I am constantly getting 'Redirect Notice' when I click on a google image. " The previous page is sending you to...http;//" " If you do not want to visit that page, you can return to the previous page " Ive tried the about:config fix and it DOES NOT WORK !

I now continuously get the error message: 'The page isn’t redirecting properly

An error occurred during a connection to amac.us.

   This problem can sometimes be caused by disabling or refusing to accept cookies'

when trying to log in to amac.us or clicking on email embedded links from them. They are a long-trusted site which I sometimes access several times a day and now will not work. Cookies are enabled for them. I even disabled my virus protection and it still gives the error.

Help appreciated.

Firefox: 101.0.1 (64-bit) MacOS Monterey M1Pro MacBook Pro 14"

When I am watching a video from inside firefox, I am unable to exit full screen mode by using the esc key. It was working before and after updating firefox it suddenly stopped.

Please assist

One part of the article I read says the connection issue is due to HTTP, another part of the Article says it is Googles fault due to their HSTS security policy. I have to say Poppycock. I can successfully login to my Gmail on my tablet I just cannot connect to it with my laptop. Firefox itself is refusing to allow the connection. Unfortunately it happens more often than you'd expect. I am in no way or by any means capable of computer repair, but I seem to enjoy tormenting myself with constantly taking apart and rebuildingthis laptop, Took me almost 3 months to finally find out how to stop Firefox address URL bar from highjacking the search bar with that really annoying awesomebar in about:config. But something just seems wrong with the browser on the laptop not being able to connect, but there is no issue with the tablet.

Thank you for any advice or solution that could help me with this. Ive thought about the firefox refresh reset option instead of uninstall reinstall, but if there is a better solution

bold textWhen I log onto Firefox I get this message. "This site is blocked because it may contain unsafe content that can harm your device or compromise your personal info.

I cannot log in to QANTAS.com.au however when using Microsoft Edge it logs in without any problems, so it is NOT a QANTAS issue. I have updated Mozilla Firefox to latest upgrade. Please help

I have been blaming this on Apple, thinking they don't want to get bad news, but if I go to the same site on my Linux machine the "I have this question/problem too" buttons work every time along with the "Helpful" one that also fails to do anything in the Windows version. Just thought someone should know.

My home page is blank. I don't know which program updated but I am pretty upset. I had an internet experience I really enjoyed and now ... it's gone.

I use Norton security. I use Duck Duck Go as my search engine Firefox as my ISP

I think I have a decent grasp of all the programs but the way they function together is nuanced and I didn't really need to understand until now.

My old home page had DuckDuckGo as the search engine, my favorite websites pinned to the upper page and pocket articles below. Not sure how most of it came to be but I like it much better than the Yahoo.com page I had set up as my homepage. If I were to hit the home icon it would take me to Yahoo.com. If I opened another tab it would take me to Shangri-la. Help!

I am unable to browse to onedrive.live.com or onedrive.com in Firefox. Works in all other browsers on my machine (Windows 10 - works in Chrome, Edge, Vivaldi, Opera) but just shows a blank page in Firefox.

I've tried in various locations, so it's not my connection. I am running the latest version of Firefox (102.0 64 bit)

The title pretty much describes the problem. Whenever I open a website that plays videos on some page in it automatically, Firefox blocks autoplay only the first time the website is opened. If I navigate through the website to another page that contains videos which the site autoplay as well, Firefox doesn't block the video from being played automatically.

I can ignore Firefox experience being worst from all browsers out there, but when Firefox randomly (delete/crash/bug or whatever) cookies so I have to re-enter everything over and over again I loose my patience.. Enabled cookie and catche deletion. Whitelisted some sites. It work pretty okay. Time after time I open Firefox, boom, all my setings gone. I'd rather use keylogger on steroids Chrome, but don't have to care about every bug in this barely usable browser..

My banking website works fine except for 2 tabs which eventually comes back with page not found due to a technical problem. I think started happening with the last update to Firefox. I have no problems using MS Edge. I have contact my Bank's help line and only suggested clearing data cache and cookies, but it made no difference.
