LibreWolf

Recently, some interactive "demo" boxes (example here) in the MDN web docs stopped working on LibreWolf for me. The preview was blank and clicking on the buttons did nothing.

Turns out I had enabled "Limit cross-origin referrers" in settings, and unchecking the box allowed MDN to work normally.

Hope this helps!

Anybody know what setting I need to modify to make weather radar sites work in Librewolf? I've tried several from my local news sites, NOAA, aviation sites, etc. They all just show a blank box where the radar graphics would be. I've tried enabling WebGL and checking canvas permissions which they don't seem to want anyway. Not sure what else could be causing this.

I only have two plugins, Bitwarden and UBlock Origin, and I tried turning UBlock off for some of the sites to no effect, so I'm thinking it has to be a Librewolf setting. The sites work fine in vanilla Firefox.

This needs to be a native feature due to its importance. Guess which browser had visibilitychange first. Quoum.

Visibilitychange is one of the many anti-features invented by Google. Mainly used to block background playback.

Well, I have noticed that I can't store or update password. If type in a password on some site, Firefox showed a popup asking if I would save it or not. Why Librewolf don't suggest me that action? I definitely enabled that function in the settings.

Librewolf versions: 137.0.2-1, 138.0.3-1 Ubuntu 24.10

Can't we make a proposal to Arch Linux devs?

I tried yet most common steps: installed the addon and gnome-browser-connector, linked ~/.mozilla/native-messaging-hosts into ~/librewolf/, but still get No such native application org.gnome.chrome_gnome_shell on gnome extensions page. Any clues how to get it work?

Latest update to LibreWolf changed it's user agent string and it's causing websites to freak out. For example amazon will default you to a mobile website and Youtube music is having issues. To make matters worse if you try to download an extension to change the user agent string, it won't let you and tell you to download Firefox. You'll need to manually override the user agent string by going into about:config. You'll need to add general.useragent.override string into config. > > > Here is how you can do that: > https://www.whatismybrowser.com/guides/how-to-change-your-user-agent/firefox > > I changed my user agent string to following and problem went away. > > > Mozilla/5.0 (X11; Linux x86_64; rv:138.0) Gecko/20100101 Firefox/138.0

I have uBlock and Canvas Blocker off, the little shield thingy off, my VPN off, and Autoplay allowed, but still cannot play videos on bandcamp. Anyone else having this problem?

I keep finding myself having to manually disable and re-enable a few different settings as I use Librewolf, namely Letterboxing and WebGL, as I switch between browsing the internet and trusted sites or home server UIs. Is there any way to configure these on a site-by-site basis, or at least from a container/profile interface of some sort?

I have tried a restart.

I keep getting this error in element

MatrixError: [403] You do not belong to any of the required rooms/spaces to join this room. (https://matrix.org/_matrix/client/v3/join/%23librewolf%3Amatrix.org?server_name=matrix.org&via=matrix.org)

Anybody else?

I was reading various old posts and the librewolf faq, but none answer my question, so here I am.

Following scenario:

I have the setting against fingerprinting enabled, which is probably the reason why a new private window opens at a set height and set width, 900 and 1600 respectively per about:config.

Now! If I maximise the window, then the inner limits of the window with a webpage do not change (as far as I can tell), what does change is that the original window is embedded now in a bigger window, the bookmarks bar (which I view as separate from the window where a webpage itself is) does stretch to fit to the new size - but as I understand fingerprinting, it's only about the part where the webpage is, not the bookmarks bar or the textbox for the address.

So why does every resource keep saying that maximising the window makes it easier to identify the user if the relevant part of the browser is kept at set height and width even if the window is being maximised? Why having the webpage kind of embedded in a bigger window if it doesn't serve its purpose: Making sure the window is the same size for every user and thus helps against fingerprinting?

Sorry if it is a duplicate, as I said I read old posts and the librewolf faq to no avail.

Thanks!

Does anyone know if anything changed with the new tab settings?

I used to have this custom userContent.css to add more columns to topSites described below, but it is no longer working after I updated :/

https://support.mozilla.org/en-US/questions/1430289

folder named "chrome" and file named "userContent.css" are still there

@-moz-document url(about:home), url(about:newtab) {
  @media (min-width: 1800px) {
    .ds-outer-wrapper-breakpoint-override main {
      width: 1700px !important;
    }
  }
}

edit: If anyone has any suggestions to add more columns to topSites, let me know edit2: solved

I was able to change the new tab favicon on LibreWolf with CSS:

/newtab favicon/ .tab-icon-image[src="chrome://branding/content/icon32.png"] { content: url("librewolf-NO8X71.png") !important; }

But I'd also like to be able to change the logo that appears on the "about:logo" page (looks like lemmy.world's CSS page is locked for now, so I'm asking here). Anyone know how to do this?

I kiped the logo from LibreWolf's reddit page, it's by u/NO8X71; tell me it's not the coolest thing you've ever seen! Wish I'd done it.

Hello librewolf community! I recently installed librewolf on macOS and am having an odd issue when attempting to view logs from my docker containers or when using the terminal in unraid. I have tried to disable a few settings but can’t seem to resolve. Any suggestions are greatly appreciated!

I recently switched to Librewolf from Firefox. On Firefox, thanks to addons, I never saw YouTube ads. Now I see them everywhere, all the time, thanks to Librewolf. What's going on and how does one change that? It's up to date and it won't let me install any add ons or plugins.

This started just today - for state highways like 99, interstate routes like 5, Smaller highways like 12, the highway number appears for a short time after a reload, but quickly gets replaced with a gray box.

Tested with Firefox and this does not happen there (Firefox ESR)

Librewolf 136.0.1-1

Possibly Irrelevant details: X11, KDE Plasma,

Was wondering why no new messages turned up, since tuesday or something. Turned out the Librewolf Matrix room is changed / upgraded or something like that. It involves joining once again. But both in Element and Fluffy clients I get this error:

MatrixError: [403] You do not belong to any of the required rooms/spaces to join this room. (https://matrix-client.matrix.org/_matrix/client/v3/join/!AMixpitUKQHatikSri%3Amatrix.org?server_name=matrix.org&server_name=envs.net&server_name=fedora.im&via=matrix.org&via=envs.net&via=fedora.im)

Is there a way to join the matrix chat room one again?

I do see the space with the 3 rooms.

This is only nice-to-have but I thought I should note it here too. I sometimes find myself looking into the browsing history to find out when I visited a certain page the last time for curiosity.

The suggestions that appear under the URL bar when typing something should also include when the user visited the page the last time.

A behaviour inherited from Firefox is that the "Del" key immediately deletes items from history. This can happen accidentally. I recommend that LibreWolf shows a warning before that.

This is something I thought Mozilla would eventually fix, but still hasn't in over a decade.

When clicking a target="_blank" link that opens in a new tab, the URL bar shows "about:blank" until the server responds.

Also, document.location.href in the console returns "about:blank" instead of the real URL. This is annoying for user scripts.

It would be better if it immediately showed the target URL. document.location.href also should immediately return the correct URL.

After right clicking a file in the list of downloaded file, an option I have been wishing for a long time is "copy path to file to the clipboard".

By that I mean the local path where the file is saved. The source URL can already be copied.

Currently, LibreWolf (like Firefox) only shows a request in the devtools after it is completed. If it fails because the server does not respond, it shows "No payload for this request".

It would be better if it showed the payload that it tried to send, even if it was unsuccessful.
