#userChrome

2025-11-14

@jbz@indieweb.social fwiw... i still use ​:firefox_nightly:​ & love it. i disable or otherwise just don't use its #AI bullshit baggage. i enjoy using its new long-awaited #SplitTabs feature. i use the brilliant #FirefoxSecondSidebar project, giving me a #WebPanel second-sidebar more powerful & flexible than any of #Floorp, #Zen [before they removed it], & Vivaldi. i use the magnificent #TreeStyleTab AO for exquisite infinitely-nestable hierarchical tabs that blows FF's native vertical tabs, chromium's, Floorp's, Vivaldi's outta da water. I use the also magnificent #SimpleTabGroups AO to give me excellent #Workspaces capability. my #uBlockOrigin is in Advanced Hard Mode, & the many tens of thousands of dynamic filter rules i've cumulatively created over the years helps make day to day browsing simply lovely. I use custom #userChrome.css, #userContent.css, & user.js files to tailor my Nightly's UX & UI "just so".

every day for many many months now i read so many posts from peeps [rightly] complaining about "what the fuck is mozilla doing to us with this ai garbage?", but who then solicit or advocate jumping to another
#Gecko variant, or [& these ones really make me roll my eyes] say they're now going to chrome coz why not... ffs.

for years i have actively also used / tested all the browsers named above [except chrome, never that pig-swill, but chromium yes], & also
#librewolf, #waterfox, #tor ... & in all cases i find various UX & UI aspects that frustrate me so much that sooner or later i always return to my bespoke #FirefoxNightly .

for those willing & indeed interested in bothering, afaict we foxxers can still have our cake & eat it.

fwiw.

​:thunderbird:​ J’ai fait une petite surcouche #css à mon #Thunderbird pour mieux voir mes mails non lus !

~/.thunderbird/$/chrome/userChrome.css

.card-layout[data-properties*="unread"] .card-container{
  background: #32302f !important;
}

C’est trop cool, car il y a un inspecteur pour l’UI de Thunderbird, du coup c’était hyper simple de trouver le sélecteur !

I've been using Firefox (Developer edition) with vertical tabs but using Sidebery, and it has worked great, but I think a Firefox update changed it so the Sidebery button would show/hide both together.

Work-around was adding the following in a userChrome.css (which I've never felt the need to really utilize before, for whatever reason)

sidebar-main {
display: none;
}

#Firefox #Sidebery #userchrome

I made a minimal firefox userStyle with a sidebar. Just when Firefox plans on releasing sidebar tabs.

But mine uses sidebery which supports tree style tabs.

#firefox #userChrome #css #linux

Если ли же вам хочется лишь небольших исправлений в интерфейсе, то рекомендую посмотреть на этот репозиторий github.com/MrOtherGuy/firefox-

Например, я пользуюсь стилем, который перемещает иконку закрытия вкладки на фавикон.

О том как настроить Firefox для таких манипуляций и разрабатывать стили: reddit.com/r/FirefoxCSS/wiki/i

Если вы впервые слышите о #userchrome в Firefox, то посмотрите, что умельцы с помощью него делают: firefoxcss-store.github.io

Скучаете по Windows 95? Нравится дизайн Safari или Arc? Легко!

Не устраивает узкая адресная строка в Firefox? Не беда, исправляется одной строчкой #userchrome

#urlbar[open] { width: 80vw !important; }

I think my #userChrome.css for #firefox is done now. I am pretty content with how it looks. Not stealing screen estate as it did before.

If anyone want to do it themselves I'll attach my userChrome.

Basically here is what you do...

Enable userChrome.css customizations in latest Firefox versions:
Open about:config
Set toolkit.legacyUserProfileCustomizations.stylesheets = true

Find menu item ID:
Open developer tools (F12)
Open the settings (F1)
Check "Enable browser chrome and add-on debugging toolboxes"
Check "Enable remote debugging"
Open browser debugging (Ctrl-Alt-ShiftI), accept incoming connection
In the browser debugging click on options button (...) > Disable popup auto-hide
Open FF context menu
In the browser debugging use "Inspect Element" to find the victim menu item
E.g. the CSS selector for option "Copy Link" is:
#context-copylink

Create "userChrome.css":
Open FF profile: Help > Troubleshooting Information > Profile Directory
Create "chrome" folder
Create "userChrome.css"
Hide menu item by adding the found CSS selector to the userChrome.css:
#context-copylink {
display: none;
}

After adding all the desired menu items restart Firefox

#Firefox 북마크 툴바에서 폴더들이 많아지면 시각적으로 구분하기 힘들어지는 단점이 있어서 그 폴더 아이콘을 없애는 방법을 찾아봤습니다.

#userChrome.css 에 이걸 추가하면 되네요.

/* 북마크 폴더 아이콘 숨기기 */
#personal-bookmarks .bookmark-item[container="true"] .toolbarbutton-icon, menu.bookmark-item > .menu-iconic-left {
display:none!important;
}

이런 다음 폴더명 앞에 이모지를 붙이니까 훨 보기 편해지네요. 진작에 이렇게 해 놓을걸.

How to fix the suddenly disappeared "close tab" button on mouse hover in #Firefox (apparently from Version 114+, mine is 119):

Drop this CSS snippet into your userChrome.css:

.tabbrowser-tab:not([pinned]) .tab-close-button {display: none !important}
.tabbrowser-tab:not([pinned]):hover .tab-close-button {display: inline-flex !important}

also if you're both "uses a menu bar" and "uses thunderbird" type of deranged, I tried to fix up the new #thunderbird UI a little bit

following up on the window focus rant from the other day, i made some small #userChrome tweaks to #firefox and #thunderbird to make window focus clearer. these kind of assume you use a menu bar tho.

I think if #firefox would get a #redesign more users would use it. A good #ux is necessary to attract users (makes sense right?). I know there are #userChrome customization options but that's too complicated for "normal people". They already have a good design-team so why don't redesign Firefox to match the look of a #ModernUI ? I would love to see that.

I know that the changes for Firefox is from 2019, but it is still relevant, that Mozilla hides more and more customization options from users...
