Firefox Support Forum

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?

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?

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.

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?

after the latest round of updates, my extension tabs (upper right) for approved and secured extensions has vanished. there is one in particular that I want in the extension area (see image 1)

I found them tucked away in another tab (upper right corner) the jigsaw puzzle piece.

is there a way to put the extensions that I want back on the extension area (upper right corner of browser window)? (see image 2)

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 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

I make themes for themes for firefox using firefox colors extension. I want to know how to change the text colour, background colour, etc of right click menus ( see image attached.

var options = {

                   audioBitsPerSecond : 128000,
                   videoBitsPerSecond : 2500000,
                   mimeType : mime
               }

Summary of my current relevant software/hardware:

FireFox (UK): 113.0.2 (64-bit)
Windows 10 Pro(UK): 
 Vers.: 22H2
 Installed on: 2021-01-23
 OS build: 19045-2965
Lenovo (laptop): 
 ThinkPad X1 Extreme Gen 3
 Processor: Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz 2.59 GHz
 Installed RAM: 32.0 GB (31.8 GB usable)
 System Type: 64-bit operating system, x64-based processor

My problems with FireFox 113.0.2 started when I began to download some Affinity V2 videos. Some of these were rather large (over 500MB) and I noticed that several were being downloaded at the same time (which was no surprise). However, after sometime I noticed that only one of the videos was completely downloaded and the others were just stopped. Then, when I looked at the task manager the number of FireFox instances was increasing: ...,5,6,...18,..

Of course, I thought I could fix the download process but all my efforts failed; e.g. after a restart of windows and execution of FireFox the same videos were still in a "hold" state and many instances of FireFox were being executed. After a frustating night of failures I finally decided to restore an older FireFox using my Acronis backup/recovery software. My last Aronis backup of my entire system was made on 2023/04/07 with the most recent version of FireFox at the time which worked fine when downloading several large video files at the same time.

I only included the C:\Program Files\Mozilla Firefox' in the restore since I have installed a rather large number of new apps and updates after 2023/04/07. This also failed -- my add-ons, bookmarks, etc. in this restored version were all missing and before I could stop the recovery process, the restored FireFox was updated to the latest as of today (2023/06/01). And of course the problem had not be fixed.

So finally to my request: What directories, files do I need to restore, from the 2023/04/27 backup with all of its features at that time -- this is important, and how do I stop it from upgrading to a newer version?

I would be glad to provide additional information if needed :-)

I dont have the split screen where you see the email header on top and the message beneath. So when I click on an incoming email, it doesn't show me the message unless I double-click it.

Hi guys,

I hope you can help. To bring you up to speed, you can check below past articles for similar problems.

This problem has just resurfaced. In a nutshell, when I type "Lost IMDb" or "Tyson Wiki" in the URL bar and hit enter, that would take me straight to that page of that site. So "Lost IMDb" and enter would take me here: https://www.imdb.com/title/tt0411008/

Now it takes me to random search results like so: https://www.google.com/search?sourceid=navclient&gfns=1&q=lost+imdb

Similar to "I'm feeling lucky" Google search is what I want back. When FF got rid of "Keyword.URL" search, I had to use an add-on such as: Google Browse by Name search engine to get similar results. Now also that has stopped working lately.

Can anyone help me get that type of search result back please?

Thank you kindly.

By mistake, I close a window with lots of opened tabs and can not get them back. In the past when this happened I went to history but now there's no available option in "recently closed windows".

I was having issues playing videos. All I would get was a black screen, but I could hear the audio. Although some videos, like facebook shorts, played just fine. And I could view videos in other browsers. Tried several things I saw suggested on threads having the same issues, but ultimately I uninstalled firefox and then reinstalled it and it seemed to have fixed the issue. Hopefully this helps others having the same issue. I tried to suggest it on a few of those threads but they were locked.
