Firefox Support Forum

Ever since the most recent update to Firefox I consistently get the following message when attempting to login to https sites which I have been connecting to for years: Secure Connection Failed

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

Error code: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.

Clearly the problem is with Firefox and not with the website owner since it occurs with all websites.

I found over 100 instances of PR_END_OF_FILE_ERROR but the few responses I looked at were back in 2021 or 2022. One solution suggested clearing the cache which I did and I was then able to connect. But now that does not help. Is my only reliable solution to delete Firefox and use some inferior browser?

I use Firefox daily, and I use Sync to save my profile.

Today I had to reinstall Windows for some reason, therefore I had to reinstall Firefox entirely. The profile files were lost in the process, and when I connected with Sync, Firefox installed all the extensions I had before, but it didn't fetch the bookmarks. Like many people, I have hundreds of links in my bookmarks, and I'd like to get them back. Profile files are not here, and Sync couldn't find them? Is there a place where I can see all previous Sync saves so that I can get an old backup (even if it's a backup from days or weeks ago)?

Hi!

Is there any way to keep an older version of Firefox without its getting upgraded all the time? Version 99 only has a small header at the top, so there is still space on my screen to see the website I'm trying to see. The newer versions (100 and newer) take up too much space on my screen. Every site has its own headers, and so I am left with about an inch of working space. That's really not enough to see anything.

Is there a way to get the security updates without the new look? Is there a Firefox Light version available, with minimal headers and all? I prefer Firefox, and would love to keep it. Having to reinstall it (to get the older version back) several times a week is not good.

Any help would be appreciated. Thanks very much!

I have few sites that pop up in autosuggestion every time I type an letter (for example when I type "i" i got autosuggestion for "imgur.com"). I want to delete these entries as they clutter my search bar. I already deleted search history with all boxes marked as checked, I used shift+delete option and every time it comes back. I want to completly delete all autosuggestion data or find a solution to delete only these I want to delete.

I still want to have autosuggestion turned on. I just want to reset it and erase it completly. I reinstalled the browser but it didn't work either.

(may have the wrong 'topic' from drop-down list) MacOS Ventura 13.4 I've tried this with Safari, Chrome and now Opera - FireFox is the only one that gets an error: "We’re sorry. Due to technical issues we are unable to process your request at this time. Please try again later."

This happens when on the TD bank site when I try to get to my "Statements & Documents" session. I've contacted TD and they won't provide what is going on to cause the above error to be generated, and because other browsers aren't having a problem it's now a Firefox issue.

I'm not sure how to proceed since I can't get further details from TD bank and don't see what needs to change to allow Firefox to work.

Any suggestions as to what setting or debugging I can try appreciated.

When I try to access my Etrade account the connection fails. Sometimes I can reach the log in page but cannot log on, Usually, I can't even access ETrade. I can log on using Microsoft Edge but not with Mozzilla,

I got this message today.... 'I then attempted to start Firefox, getting the error, "The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem."'

I attempted to reinstall Firefox and am still getting this message. How do I fix this?

Each and every time you install an upgrade on Firefox, your profile vanishes. So I questioned on how to save my profile and I found a nasty solution where you have to close Firefox because of a stupid empty file named parent.lock which happen to be empty on the 2 cases I checked. I did not sniff in the restore constraints yet... What a mess ! Looking at the frequency the Firefox's upgrade arrives, it would be advisable to automatically preserve the user's parameters. Alternately it would be a good thing to have a save/restore function for Firefox's parameter.

I've just noticed whilst writing a blog on wordpress that my firefox built in spellchecker is no longer working. It no longer works on wordpress. It no longer works on any other page, including this one. Here is an example sdhflakshfldfjl - included in the files below. Thanks in advance.

I have used both the latest downloads for Firefox and the Private Browsing and have the same problem. Tabs won't open. Even a new tab to open Mozilla support won't open; I had to copy the URL and then open in the Private Browsing program to get in here. Then, the tabs that were already open on various sites freeze. What's going on?

I recently tried to log into my Firefox account on a new PC I am building. I have Bitwarden as a PW manager and I use the 2FA inside of the paid version as much as a possibly can. I have it setup for Firefox but no matter what I did I could not get past Firefox's account 2FA page it kept giving me a wrong password. I saw that Firefox has a list of authenticators that will work(https://mzl.la/3p8DJls), is Bitwardens 2FA function not capable of working with Firefox accounts?

Im using Firefox desktop version 113 with win 7 Browser will not save logins or passwords either saved by me manually or by importing from chrome.

Below you will see the screen from my settings after saving. Strangely, I do get the prompt to save them. See other image below.

I do not want to use sync. I only want firefox to store this locally as the earlier versions did without any issues.

Thanks

Hello to the Firefox team, if we reset Firefox, will the list of certificates also be reset? What are certificates and how does it affect the opening of sites? What happens when we delete them? How to recover if deleted? Grateful!

I've been using firefox for last 15 years now to do my online banking with RBC. As of 2 weeks ago it has failed to open online banking on the RBC website. Google chrome however works. When speaking to RBC customer support they say it is a problem with firefox and will likely go away once firefox updates to a newer version.

Hope you can help with this issue since my browser of choice is firefox. Thanks
