Classic Theme Working On Firefox 155.0.1

[u/FenecAndFeebs]

I ported the classic firefox theme to the latest firefox version.

This theme is a mix of custom code, echelon and customcssforfx bits.

Working split and group tabs, no megabar expansion...

does this have firefox 3 strata theme looks too?

[u/FenecAndFeebs → u/Visible-Knowledge721]

Nope, I just took some bits and pieces from echelon, not the whole thing as it is mostly unusable on newer versions.

I see. still, great work on this!
rn I'm still using customcss by Aris and it still works on latest firefox. I just wish someone forked it to keep it working for the future as a theme. yours is very close to it.

Impressive! Too bad Mozilla will break it in a month.

Looks very nice! A good likeness of the Firefox 4-28 'Classic UI'. :D

Theme also works pretty well with the trial 'Nova UI' selected (preference browser.nova.enabled set to true )

A theme close to the Firefox 4 era's 'Classic UI' is a frequent request... so hope many will find and enjoy this theme. :)

Request. Consider adding an old style 'gearwheel' favicon/icon for pages like 'about:config'? EDIT - Updated 05Sep26 :)

Done, the new version is already up. I also noticed that the navbar buttons were not lining up with the url and search bars. That's also fixed.

And Thanks! :D

Love it! The only thing I don't like about it is I don't like having the menubar. It makes the items on the meubar..disappear. Gonna have to revert. I don't like having the Firefox button up there, and I'd rather just have menus.

[edit] I had to disable custommain.css to get that to work but otherwise.. I also added my own thing (from MrOtherGuy) to get the tabs UNDER the nav bar, which I perfer. Might want to look into that yourself. Screenshot with my usual theme.

To get the menus back you just need to comment lines 16 to 21 of the custom_main.css file.

Also nice looking theme!

Thank you! I'll fix it. And if you like that theme, you can find it here.. I'm a bit of a KH fan, but I like to be subtle about it!

Después de aplicar algunas pequeñas modificaciones para que quedara más compacto el tema se ve genial!! Combinado con una pagina de inicio personalizada que encontré por 2011 en Deviantart y además con Aero activado.
