LibreWolf

I just added a link to to my blog's RSS feed in the blog index page, and Librewolf now has a Reader View button for that page, which seems to let people read RSS entries instead of the normal HTML pages. The reader view also includes read time estimates. The index is about one minute, and an entry i clicked says 2-3. Where does this estimate come from?

In my userChrome.css file, I have the following so I can have a "compact view" of bookmarks, menus, etc.:

:root{ --arrowpanel-menuitem-padding-block: 2px !important;}

The Sidebar still displays bookmarks, history, & synced tabs "compactly", but the items on the hamburger menu and in the folders on my bookmarks toolbar are given "Normal" (spacey) density. Any way I can fix this?

I am trying to connect to a .local website, and LibreWolf says it can't connect to server (one of the worst UX error pages I've seen). Google and DDG are of no help, and I do not want to resort to using another browser for something that should be simple to disable.

I have added my domain to network.dns.localDomains and that did not appear to work. I have "DNS over HTTPS" disabled completely. I do not know what else to try.

Please help.

I can't update LibreWolf on Fedora because the signing key seems to be revoked.

I get this when I run sudo dnf upgrade librewolf:

--------------------------------------------------------------------------------

Then I tried importing the key manually from https://repo.librewolf.net/pubkey.gpg:

$ sudo rpmkeys --import pubkey.gpg 
warning: Certificate 40339DD82B12EF16:

I could disable the signature check, but I'm worried now.

gpg --show-keys pubkey.gpg shows this:

I think I did some updates since April 25th. I don't understand why it doesn't work now.

Does anyone know if it is possible to recover the pinned shortcuts that I used to have on new tabs?

I updated to the last version, my pins were wiped and I have fewer shortcuts columns as well :/

The thing just much more convenient to use. Unless there's some security/privacy related thingy that forces the change.

I've tried searching for what the cause of this is but I've had no luck so hopefully it's ok to ask here.

For some reason LibreWolf is displaying pages with a significant amount of spacing between words/text justification.

The screenshot provided shows how the LibreWolf docs page looks in Firefox on the left and LibreWolf on the right. I am currently running LibreWolf version 141.0.3-1 on Kubuntu 25.04

Is there some way to alter LibreWolf so it renders the text more like the Firefox does or is this finger printing related i.e. intentional?

Thanks!

Here's how LibreWolf currently looks for me. Aside from the sidebar and some stuff removed from the toolbar, it's pretty standard.

And here's how i'd like it to look, with no toolbar and less stuff in the sidebar.

The back/forward/reload buttons are moved to the top of the sidebar. The window controls are moved to the bottom of the sidebar. Settings & history are replaced by bookmark and menu. And keyboard shortcuts exist to access the address bar, like in Links.

This layout saves space for the content of pages and relies more on keyboard shortcuts and less on the mouse.

Is this possible without making my own Firefox fork?

Trying to load my usual Proton Mail web app and I get an error that is completely un-bypassable. Details of the error say "This version of Firefox is no longer supported due to a bug in the WebCrypto API. Please Update to a newer version".

Has anyone encountered this and found a fix? Not sure the devs are aware either. Any info is appreciated.

EDIT: Issue was somehow my LibreWolf was not updating as a result of various package manager repo things. Manually updating the install to the latest version fixed this problem.
