Plex media server.exe is trying to access your login info in Firefox?

Server Version#:1.25.3.5409
Hi all
Avast just flagged plex for trying to access firefox log in. I can’t see why it would be trying to access it?
I can block or allow it, but I’m concerned it will block the whole app.
Anybody throw light on this?
plex trying to get firefox log in 2_LI

To access your server, the web app needs to be logged in to your plex.tv account. To do that, a username and password is necessary.

Thanks, are you saying it’s trying to log into plex via FF? Even though I don’t have FF open?

Did you perhaps click on “Open Plex” in the right click menu of the Plex task tray icon?
Because that will cause the default web browser to open and to load the Plex Web app.

Actually, I don’t think that’s so, I just checked and Chrome is my default browser as I thought. Maybe there was a background process that’s provoked this, I did check that as well, but could see nothing.
I think it’s the way Avast worded the alert that had me thinking maybe plex.exe was after my Mozzila credentials, As long as it’s just Plex trying to log into Plex then I’m fine with it. Not unusual for Avast to alert a false negative.
I wouldn’t say I understand this yet, but less concerned.
Thanks for your input, it has helped.

Avast will pop this message when an application tries to access the Firefox logins.json files.

This wouldn’t happen when using Firefox to access Plex.

This makes me wonder what folders are configured in your Plex Libraries.

If Plex was configured to scan C:\ or C:\Users\YourUser then this would occur.

PMS has no knowledge of what browsers are installed on the OS it’s running on!

As such, it’ll should never ever try to access the file you mention, AFAIK

Can you reproduce this, and if so, then please provide PMS Logs right after this

Hi, thanks for your input.
I’ve just booted up the same laptop, and yesterday that’s all I did do when I got the flag/avast warning. I will message here what happens. Yesterday, I wasn’t happy to block PMS via avast, so I exited my plex server as opposed to blocking it or allowing it, & did not reboot PMS after, but now with a fresh system boot it has obviously started my sever.
On the paranoid side, could someone of hacked my plex account & be trying to access other data?

I’d first verify @Volts ’ theory above by checking the “Add Folders” tab of all your libraries.

Hi, thanks for your input.
I don’t use FF much nowadays, I always use Plex web via Chrome to access on my pc’s, or Android & various dongles for tv.
Can you expand a little about configurations of folders, PMS has general access to all of my media folders, I do try to be organised but I do add random folders to the libraries.

This could be so, I will check.

I think we might be getting close to the problem here.
So if I had added C/user/*****/downloads/randomfolder to the library, this is what is being described?
Only thing is (without reading that article, which I will, just got in from work)
Where else would I be keeping my media files other than c drive / user? Partition?

No, because that path doesn’t contain the Firefox Profile. (Unless the forward slashes are an issue. Or unless there are hardlinks, but those are unusual on Windows.)

If something like C:\, C:\Users\, C:\Users\YourUser, or C:\Users\YourUser\AppData\ have been added to any Plex Library, then Plex would scan that folder and all subfolders, which would include the Firefox Profile.

Plex Libraries should be configured to point at folders that contain media, as outlined in the links shared above. They shouldn’t point to C:\ or any active downloading or processing folders. Instead, move media files into a Plex Library folder after processing is completed.

@dane22 suggested providing the server logs. If you’ve gone through the Libraries and don’t see anything unexpected, providing the server logs might allow somebody to investigate further.

Errm, yea the forward slashes was just me trying to use the same language as you, I didn’t check, for starters, I should have used backslashes.

Oh, I see, I think I have missed something fundamental here, The Plex library folder is an internal Plex exe folder?
I have always, for some considerable years, just added any folder that had media that I wanted to be included.
Facepalm moment?
I’ll go through the info pages about adding to libraries, I’ve not paid enough attention obviously. & happy to pass on log files if still wanted.

Sorry; when I say “Plex Library folder” I mean a folder that you’ve added to a Plex Library.

I think we’re talking about the same thing - Editing Libraries | Plex Support

It’s absolutely fine to add many media folders to a Plex Library. You just don’t want to add other things to a Plex Library - not the C:\ drive, etc.

You definitely shouldn’t put media into any internal Plex folders.

This might not be the issue anyway, of course! But it’s a strong hunch - that’s the only reason I can think of for Plex to attempt to scan or access the Firefox Profile folder.

I’ll mull it all over, & get back here sometime soon.
Thanks though, I do tend to stumble my way through without much technical knowledge.

:sunglasses::+1:

Doesn’t seem like you’re stumbling much to me. These computers are dastardly tricksters. :slight_smile:

No reoccurrence today. Are the existing logs of any use?
It’s going to take me a bit of time to go through suggestions here, but I wanted to offer the logs I have just downloaded.

I would like to see fresh logs, right after it happens

Ok, understood. If it does, I will.
