Background:

I think I messed up ... Wanted to get a lot of files out of a nested folderstructure 3 levels deep and used mv /*/*/* ./ somewhere deep in my personal folders. I got a lot of errors and quick as I could stopped it. Now that folder is is messed up with a lot of stuff (see below) which I dont know the origin of. The good news: I have fairly recent backups

Questions:

• Could they be from subdirectories in my home folder?
• Could they be from subdirectories outside my home folder? Especially grubenv caught my eye.
• Could it be potentially dangerous to reboot? I leave my PC on untill I know more.
• Would it be possible to reverse the moving in some way, to put them back where they belong, even manually?

Any help greatly appreciated.

Files:

I know Apple's adaptation of Asimovs books got off the rails but didnt expect this crossover ...

I use Firefox (LibreWolf with Mozilla sync) on multiple devices. To have my tabs, extensions and history easy available I use Mozilla for syncing that data.

Would it be possible to just use a generic sync service like rsync or something, to sync the profile folders and every file in it?

Or would that break or corrupt data?

I didnt need even more motivation to degoogle but got it anyway.

My questions are:

• Does the DuckDuckGo Firefox extension "Privacy Essentials" add a local css file to every visited site?
• Can others reproduce this?
• Is this harmfull or not?

Background:

I have a simple static one page site with just one html and css file. It's completely tracker free. Debugging it a bit with developer mode (F12) on I discovered a second css file. This file isnt on my webserver but added local. To pinpoint what caused this I removed every add-on / extension in my browser one by one, reloading and checking my website every time. Took me a while because didnt expect this one causing it.

To reproduce:

• Install the extension from the link.
• Open a random site
• Check in developer mode the tab Style editor.
• Scroll and look for a file named %3Ais(%5Bid*%3D'google_ads_iframe'%5D%.css or something like that.
• Remove the extension and refresh.
• Check if the file disappears.

Content of the css file: :is([id*='google_ads_iframe'], [id*='taboola-'], .taboolaHeight, .taboola-placeholder, #credential_picker_container, #credentials-picker-container, #credential_picker_iframe, [id*='google-one-tap-iframe'], #google-one-tap-popup-container, .google-one-tap-modal-div, #amp_floatingAdDiv, #ez-content-blocker-container) { display:none!important; min-height:0!important; height:0!important; }

Edit 25-03-2024: Changed title to not give the wrong impression. See comments below.

My main question is about /run/user/1000:

• Should I avoid touching it?
• Could I delete it?
• Is there something wrong with it?

Background: I'm fairly new to Linux and just getting used to it.

I use fsearch to quickly find files (because my filenaming convention helps me to get nearly everything in mere seconds). Yesterday I decided to let it index from root and lower instead of just my home folder.

Then I got a lot of duplicate files. For example in subfolders relating to my mp3 player I even discovered my whole NextCloud 'drive' is there again: /run/user/1000/doc/by-app/org.strawberrymusicplayer.strawberry/51b78f5c/N

Searching: Looking for answers I read these, but couldnt make sense of it.

• https://unix.stackexchange.com/questions/162900/what-is-this-folder-run-user-1000
• https://forums.linuxmint.com/viewtopic.php?t=412850 So if its a bug with flatpaks I'm inclined to delete a certain db at ~/.local/share/flatpak/db

Puzzled:

• Is this folder some RAM drive so my disk doesnt show anything strange? Because this folder doesnt even show up at the root level.
• Are these even real? Because the size of it (aprox 370 GB) is even bigger then my disksize (screenshot).

Any tips about course of (in)action appreciated.

Although the headline focusses on a obvious category of media, it really can go wrong on a lot of other categories as well.
