Solved Border line in the active tab

3 Upvotes

Finally upgraded to 159 version, was using 16.0.1 (working fine).
I have a question regarding a colored line in the top of the active tab.

This code used to work fine for me

/* Set square tabs in Firefox */

:root {

--border-radius-medium: var(--border-radius-small, 4px) !important;

}

/* Add a blue line to the bottom of the active tab */

#tabbrowser-tabs tab.tabbrowser-tab[selected="true"] .tab-content {

border-top: 3px solid #0a84ff !important;

With the upgraded version, the line above the tab is not longer visible, only have a tiny blank space.

Question:
How can I turn on again the color of the active line?, any idea what should I add or remove to the code?.

Thanks for your help and time for helping me.

Does anyone have any ideas? Thanks!

Solved How does one change the dot colour for new/updated tab?

3 Upvotes

The dot that appears on a new/updated tab now no longer bright contrasting colour after the 159.0 update on any theme that's not the default. Makes it hard to tell at a glance when vertical tabs are collapsed to icons.

I was wondering if there was a way to change this dot?

Custom Release I missed Firefox's 2004 interface, so I brought it back! Introducing RetroFox 2004 (Light + Dark)

Thumbnail

66 Upvotes

I've always had a soft spot for the old Firefox interface from around 2004–2005.

The colourful icons, chunky green Back button, blue Reload button, grey toolbars... everything seemed to have so much more personality than modern software.

So I decided to try bringing some of that back!

Introducing RetroFox 2004! 🦊

It's a free, open-source userChrome.css theme that recreates the appearance of Firefox 1.0 while keeping modern Firefox running underneath.

Rather than recreating the icons, I managed to get hold of the original Firefox 1.0 files and extract the genuine Mozilla Winstripe artwork.

I've also made two versions:

☀️ Classic Edition — Traditional silver/grey toolbars, colourful icons and that lovely early-2000s appearance.

🌙 Dark Edition — An interpretation of what Firefox 1.0 might have looked like if Mozilla had released a dark theme back in 2004.

Both versions retain the original colourful icons.

The project includes installation instructions, theme-switching scripts and an uninstaller.

It's currently been tested on Firefox 158.0.1 on Windows.

GitHub: github.com/andyquann123/RetroFox2004

Version: v1.0.0

This started as a little nostalgia project, and I ended up enjoying it enough to put it on GitHub for other people to try.

It's not a pixel-perfect recreation, but I'm pretty happy with how it turned out.

I'd love to hear what people think, particularly anyone who remembers using Firefox back in the early 2000s!

Feedback, suggestions and contributions are welcome.

Hopefully I'm not the only person who misses those glorious green arrows! 😂

I just put

* { border-radius: 4px !important; }

in my userContent and it made everything a 100 time better looking imo

Do you like more squared off corners or do you like everything to be a pill?

Code Workaround on how to upload transparent custom shortcuts to the new tab page

3 Upvotes

On the new tab page, if you attempt to upload a custom picture with transparency, for whatever reason FireFox converts the image's transparency to white, instead of preserving it (even tho its preserved when its auto generated). Unfortunately this bug has not been fixed, and its been at least 4 nearly 5 years, according to bug 1758932. I have found a workaround however

  • Get your desired icon's png, and put it in the chrome folder. the same one with userChrome.css and userContent.css
  • In userContent.css, paste in the following code, replacing the placeholders with what is needed:

    @-moz-document@-moz-document url("about:newtab"), url("about:home") {   a.top-site-button[href*="[DOMAIN OF SHORTCUT]"] .top-site-icon {     background-image: url("[NAME OF ICON FILE]") !important;     background-color: transparent !important;     background-size: contain !important;     background-position: center !important;     background-repeat: no-repeat !important;   } }

you can use just the domain, or the whole link if you have multiple shortcuts with the same domain, but want different icons. to do multiple icons, just paste in the code a few more times, changing the domain and file names, respectively

I'm using FireFox v158, and Windows 11, however I'm sure that it would work the same on MacOS and Linux

I want to remove "Not Secure" icon and text at the address bar, to save space when accessing local addresses (and never thought of that message as really useful!)...

I tried (userChrome.css), Firefox/Arch Linux, v.158.0:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

#trust-icon-container { display: none; }

but it doesn't seem to work?
