What is this about? Just trying to reach https://www.scientificamerican.com/

Never happened before

This does not happen when accessing through Firefox on my iphone....just on the macbook

Hello, when I browse the internet, randomly the certificates seem to break as I get https certificates for sites that seem to have nothing to do with the sites that i intend to visit. Then errors like the ones in the screenshots appear. Usually reloading the website helps and then the certificate displayed seems to be correct. I did make sure to upgrade to the latest version of FF (136.0) and I did clear all cookies, but it didnt help. I do not really have any idea where to start searching or what might cause this, tia for help. kind regards Thomas

I get this error code when I click this link: https://app.getresponse.com/click.html?x=a62b&co=zuZIy&lc=hxmU75&mc=Iu&s=Hb9xCO&u=qU&z=EF9yGAP&

This is for any link on 1Funny.com Newsletter

Using Windows 11 just reloaded on new hard drive (Solid State). Old hard drive took up smoking. This error does not happen on any other site and did not happen before.

We have systems on our network that run Mozilla Firefox when accessing a specific URL are able to do so with no issues. Then we have other systems in our network that run Mozilla Firefox when accessing that same URL received the following error:

Secure Connection Failed

An error occurred during a connection to "URL". PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

Both are running the same version of Firefox. The only difference I have found is the DNS over HTTPS status. On the one that the user is able to access the URL, the DNS over HTTPS status is off. On the one that the user is unable to access the same URL, the DNS over HTTPS status is Active using the provider Cloudflare.

These are both brand new install of Firefox and there was no configuration changes. We don't use any GPO's or anything else to manage Firefox. Why would one be off and the other active? This is causing issues.

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.

Examples of webpages I've entered today that receive an error message are https://leafscape.com & Mint Mobile

Every time, but only in the last two days, I try to click through to anything related to American Partisan.org, get a "bad request"error message. I have never had this problem in many years of visiting this site and clicking various linked articles on site. I am still receiving email from this site daily with no problems, but cannot click from the email to the site itself. I am not very computer savvy having grown up using a dial telephone in another millennium. I hope the solution is simple. I have no such problems with the site in question on the same email account on my cell phone. I have no similar problems with any other sites on my computer. Here is the message:

Bad Request

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.

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.

I am being prevented to access any sites I need just because they require some personal data from me. After the initial Norton (1). The message I receive -

I am unable to watch movies on paramount +. it says unable to load code 111. has something to do with blocking or firewall or I really don;t know. I am 86 yo and have no grandkids close. HELP

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)

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.

PR_CONNECT_RESET_ERROR

I'm tired fixing errors which become more complex and solutions are written for people who have the time an knowledge to waste fixing these constant issues in FIREFOX, Time to change browser.

why do I get this error page when I click on an e mail from Homedepo.com and it I type homedepot.com I get in with no problems. I tried to wipe out the cookies and I wiped out everything that made life easier and made even the easy things like signing in (or really I never had to re sign into my e mail) to my hotmail or gmail? I don't have this problem on my Linux laptop?
