Firefox Support Forum

Hi need to get my old firefox back before installation of new version.

I have a subscription that allows for downloading of videos using a "DOWNLOAD" button that has disappeared after new version of firefox was loaded. also my antivirus application has disappeared. How do i put everything back the way it was. I'm using windows 10.

Please help

I have been using Firefox as my preferred browser on Windows 10 Home and Pro systems for a considerable time and have recommended it to many Windows and Android users.

Windows 10 Home ver 10.0.19045 has recently been unable to access many well-known websites due to

Secure Connection Failed - An error occurred during a connection to <website's https url> PR_END_OF_FILE_ERROR.

There are multiple reports of this problem from 2023 up into 2024 in Mozilla support and across the web, but no solutions. Curiously all of the problem reports mention Firefox not any other browser. Suggestions to try multiple fixes, but none have resolved the problem.

One posting on Mozilla Support marked RESOLVED says the problem mysteriously went away for that user. Lots of people still seem to be having this problem, so how about a fix.

Sent from Brave browser,

It was working fine and now the past few days I can no longer login to my Fastmail.com account other than from my Windows 7 pc

So no one including Firefox can email me

Hello,

My password saved are deleted every time I close FF. It used to be manageable because Google and other sites didn't require me to fill my passwords (cookies did the trick I suppose) but now I also loose access to gmail and Youtube every time I close FF. It's annoying to have to use 2FA every damn time. And keeping the passwords available.

I've tried every answer I found by looking around :

- tried to start in safe mode - disable hardware acceleration - I have no extensions

FF saves the passwords correctly (at least they appear in the saved password tab) but they are erased every time I restart FF. The cookies aren't automatically deleted (FF remembers my browsing history) but I need to relog into Google.

I getting frustrated.

control + UP (arrow) is documented to "go to top of page". That has broken as of 126.0 And, for some reason I don't remember, I found that using "HOME" in the past was also problematic.

How do I report something as "b roken" to firefox and do you agree it is broken?

I use firefox (as mozilla) for decades ago. Never had issues, is super easy, fast and ...secure (?) A hacker last week have access on my Firefox, download ALL my saved passwords as CSV... as a plain TEXT and ATTACKS on my entire life!!! And the nightmare goes on and on... Stole my primary Google Account, Facebook, Instagram, Ubisoft, PayPal, Microsoft Account.... and other 20 sites beside this. For GOD sake, didn't you EVER think to place an extra security layer on this EXTREMELY SENSITIVE details??? A master password? 2FA or something else? Are you serious??? I'm so sorry BUT YOU'RE LOST MY TRUST!!!! Period!!! Give a change to your selves and PROTECT YOUR CUSTOMERS!

I have been using firefox for years. My current version is 126.0.1 (64 bit). Within the last couple of months(?) I am unable to reach a website that I use on a semi-regular basis axisgis.com/AshbyMA The problem exists on 3 different devices, an HP laptop running win 10, an older desktop running win 10, and an older mac desktop running Catalina 10.15.7 which apple says is up to date. If I use Safari on the mac the website works perfectly. If I use private browsing on the laptop the website works perfectly. If I use private browsing on the desktop the website works perfectly. On the laptop I ran the firefox in troubleshoot mode and the website still would not work. I cleared the cache on the laptop and the website still won't work. Since the problem occurs on 3 different devices that are not synced to each other I can't believe it is a cookie problem. Rebooting devices makes no difference. I rebooted the Comcast modem and the house router, no change.

Any ideas would be welcome.

Thanks, mike

Hello, I have problem with firefox. When I try download from facebook page files .docx, .xlsx (Microsoft Office) Firefox automatically download it as PDF and file is broken. I don't know how to repair this. Please help, it is very frustrating.

I can no longer connect to X ray images using your browser. The links are in EPIC. The X ray system is eUnity. If I can no longer connect I will have to switch browsers.

Your browser says: Secure Connection Failed

An error occurred during a connection to webpacs.cei.med.umich.edu.

I am trying to email a link from chatgpt to my yahoo email account. When I try to open the link I receive the error 500 internal server message. I have emailed links from chatgpt many times before with no problem. Can you advise.

Thank you Barbara Krausher

I am trying to sync my addons to another computer. Apparently the addons I have on the primary computer are not synced to the server. The sync-log says "[addon] not syncable: is foreign install." The About Sync addon shows that data for two addons are on the server, one of them About Sync, while I have a lot more on my primary computer. I may have synced the addons from the secondary computer first, so that might explain why the server knows only about two addons.

So I am trying to wipe the addon data from the server and sync the addons from my primary computer. I have signed out all but the primary computer from the Mozilla account. I have tried signing in and out of the Mozilla account and changing the password to wipe the server data, but that does not seem to work.

Wiping the addon data via About Sync > addons > Engine Actions > Wipe addons does not seem to work, either. After syncing About Sync shows that there are two addons on the server again.

What else can I try to wipe the addon data on the server or to sync my addons from the primary to the secondary computer?

Recently my browser will open a Settings tab whenever I click on an autofill dropdown selection. Any autofill selection from username/passwords to simple Name/phonenumber/etc autofills. It's very annoying and I can figure out why it's doing it. How do I make it stop? I'm running Firefox 126.0.1 (64-bit) on a Windows PC.

Why do I need a new profile every single little update? How can I get my saved session, bookmarks, history, open tabs, extensions and preferences from my old profile? Manually copying files from the old profile is not a solution - it's a workaround and not a great one. Lots of things get left behind. Alternatively: what file in my "old" profile do I need to manipulate to trick Firefox into using it with the new version?

Hello, I've chatted with the creators of the add on "Twitter X Ad Blocker" and asked why it isn't working any more. They told me they have an update made and ready but you have not approved it yet. What will it take to get you to approve the update so this will work again?

Thanks, Tracy

Please help me to understand why I keep getting the 'Gah! Your tab just crashed' message. This only started a couple of weeks ago, but is extremely annoying and makes me doubt the integrity of Firefox. The problem can be circumvented (at least for a while) by closing and re-opening Firefox, but I'd prefer not to have to keep doing this.

My system repeated asks if I want Firefox to be my default browser. Equally as many times I have indicated yes but why doesn't it stick? Running Win10 latest update. Please help me get rid of this annoyance.
