Firefox Support Forum

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.

When opening Firefox for the first time after turning system on for the day, Firefox has for some reason opening a separate window With this address: https://addons.mozilla.org/en-US/firefox/addon/avg-online-security/?src=external-app-newtab-store I do use AVG as my anti-viral program but am not interested in using this add-on. I have looked in Firefox setting, and can see no way to stop it. Do you have any ideas, PLEASE? I will try to add a screenshot of the screen for you to view, if that helps!! THANK you!!

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?

When I switch from one tab to another doesn't matter the webpage the page adjusts the content on the tab. For example I was on youtube and switched over to gmail and it adjusted the screen and when I switched back to youtube it did the same on youtube. I wasn't zoomed in or anything. I was just on the tab and it was fine and looked how it should but as soon as I switch to another tab it does it on that tab and then will do it again when I switch back to the tab I was on originally on. I'm on FF vers 113.0.2 (64-bit).

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?

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

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)?

Hello,

Each time I start my computer and launch FireFox I am greeted with the "Welcome" page as if it was the first time I launch it. My extensions do not load and I have to manually turn them off and on again for them to load properly. The permissions I gave them previously need to be reconfirmed.

It's as if FireFox doesn't remember me at all. It wouldn't be that problematic if not for the issue with the extensions.

I've searched far and wide and couldn't find any solution to my problem. If anyone has any tip I'd be grateful, I already forgot half of what I've already tried but I'll let you know.

Thank you ! :)

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?

Hello

Noticed in the last few days I cannot change the proxy settings. Use to be able to. I am on the latest version of Firefox as of today. Try to run Firefox as an administrator but still greyed out. Not sure what is causing this. This is on Windows 10 and a 11 device. Do not have any GPO for firefox. Any idea how to find out what is causing it or ho wto fix it?

So I'm on my dad's computer, he's old and doesn't get the computers. Anyway he has two pinned Firefox's and I told him to delete one and he said no way because they open different firefoxs, and sure enough they do. One opens with a completely different homepage and completely different set of data and saved passwords and websites than the other. The only difference I could tell is that it seems like one he's created a firefox account for and the other doesn't have it. But why would a shortcut open up a different instance of firefox like this? Is this some scam browser that's cloning his firefox browser? Or is this some weird thing that is an only firefox option?

The browser I'm on now says this under about:support

Name Firefox Version 113.0.2 Build ID 20230522134052 Distribution ID Update Folder C:\ProgramData\Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38\updates\E370DFFC6E748E8F Update History Update Channel release User Agent Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/113.0 OS Windows_NT 10.0 19045

And the other browser says this: Name Firefox Version 109.0 Build ID 20230112150232 Distribution ID Update Folder C:\ProgramData\Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38\updates\308046B0AF4A39CB Update History Update Channel release User Agent Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/109.0 OS Windows_NT 10.0 19045

Maybe somehow they just didn't realize each other when a new one was installed?

Any help would be appreciated.

Hello,

I am trying to understand if there is a way to customize the tab rearranging behaviour.

In particular, the thing I find very unpractical is that, after a tab is closed, the others do rearrange, but after the mouse goes out of the tab bar. This is particularly annoying when I have to close multiple tabs, since thanks to this behaviour, the tabs which I close after the first one are always the unintended ones.

The solution would be to let the tab rearrangement happen instantly after the closure of the tab. In my opinion even without animations, I do not really care about that.

If you have any suggestions let me know.

Thanks in advance!

Hi all,

I have prompt in Firefox that says "Your browser is being managed by your organisation". I've done a bit of a google and appears to be anti-virus related which I don't have any installed.

Certificates ImportEnterpriseRoots is also set to true.

What would be causing this?
