I haven't upgraded browser versions for a while and I'm now going from 109 to 132. Pretty bad I know.

I'm having a number of issues but for this post I'd like to concentrate on userChrome.css.

In version 109, I had a custom font for the top menu bar, the top menus, the bookmark toolbar, the bookmark toolbar menus, and the right click menus. I did this by including the following in userChrome.css (as per [https://support.mozilla.org/si/questi.../1335097|here]:

1. navigator-toolbox { font-family:"MyFont" !important }

This worked great, but it is no longer working in version 132. Obviously I don't know in which Firefox version this stopped working.

Has this been disabled by Mozilla or has it been changed? If it's been changed, how can I achieve it now?

I'm very grateful for any help!

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

Hello all:

Just downloaded version 140 and ran into an immediate "visual/appearance" problem with regard to the background color(s) of the sidebar bookmarks view. Many themes now have totally dark sidebar colors and not readable (see screenshot image upload with this posting). I always have my bookmarks (almost 1200 of them) displayed in my sidebar, and this is the first time an issue like this has arisen with a Firefox update.

To remedy this scenario, I must use very light colored themes that have a white background when you bring up the sidebar bookmarks. If not, everything is totally dark and unreadable.

Any ideas or help on this one?

Dear Mozilla Geeks—

As practically every other Firefox user, my bookmarks evolved into a lengthy file system that uses folders to segregate categories of bookmarks.

That is, it used to have this feature.

After the last update all or most of the bookmarks (I can't tell by scrolling down the long list) are devoid of their organizing folders. This puts a great deal of information beyond easy reach. In Mozilla Help topics one is advised to click on the library icon in the toolbar ... only there is no such icon on my copy of Developer's Edition.

Can someone suggest a method or methods to recover the folders?

Some passwords have been lost as well.

Yours Sincerely,

Glen

I have 2 instances of Firefox: I use stable for all my professional work, and I use Developer Edition (Aurora Channel) for personal things. The stable branch works fine. In Aurora though, certain key combos will not work. This even persists in troubleshooting (safe) mode.

Specifically, it seems anything using both ctrl+alt will not register alt, only ctrl. alt, alt+shift, and ctrl+shift all seem to work fine, but ctrl+alt and ctrl+alt+shift do not. Again, this works fine in stable, so I am clueless as to why it doesn't work in my other instance.

Another detail is that this happens on multiple websites, not just one. The post prominent one is Google Sheets. In sheets, you can insert the date using `ctrl+;`, the time using `ctrl+shift+;`, and both using `ctrl+alt+shift+;`. Inserting them separately works fine, but both causes only one to insert.

Since version 148.0b2 (64-bit), it's once again not possible to enter search terms in the search box of a new tab; instead, the browser searches in the address bar. I've had all the settings I found in the forums configured correctly for over five years, and they haven't changed. - browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar = False. Despite this, the search still occurs in the address bar. Now I'm back to the awful search in the address bar. How can I fix this? Please fix this bug as soon as possible.

Original: Set der Version 148.0b2 (64-Bit) ist es wieder nicht möglich die Suche im neuen Tap, im Suchfenster einzugeben, sonder es wird wieder im Adressfeld gesucht. Ich habe alle Einstellungen, die ich in den Foren gefunden habe schon über 5 Jahre so eingestelle, sie sind auch nicht geändert. - browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar = False. Trotzdem wird die Suche im Adressfeld geführt.

Jetzt geht es aber wieder mit der Schrecklichen suchen in der Adresszeile los. Wie kann ich dies ändern? Bitte diesen Fehler (Bug) schnellst möglich beheben.

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

I'm a beta update channel user, so this may not reflect what 'normal' users are seeing. I use Firefox in Linux, debian v13, so normal people that are using Windows or MacOS also might not see the changes I'm asking about? -- I have no way of knowing.

Anyway: in FF v152.0b6, the "Connection Settings" area seems to have disappeared entirely from the settings menu. I used this area of the settings frequently.

The ability to set proxy still exists in the about:config settings area. In the future, will about:config be the standard place to go for people that want to manually set (or toggle) an http/https proxy?

Thanks for reading, and thanks to all the Volunteers who make this place and Mozilla software function. I use your stuff all day, every day, and my life is better because of it.

Web pages that are supposed to contain emojis are blank. I can highlight where emojis are supposed to be shown but the actual images of the emojis aren't there. about:config font.name-list.emoji correctly contains "Apple Color Emoji" If it is relevant, this has been a bug/issue that has persisted for a couple of months now (can't name an exact date).

When we are getting dates and time in history like Chrome? Random months and in those months, no days, no dates makes Firefox outdated.

Is Firefox not growing or everything needs to be highlighted? I have never highlighted anything to chrome yet it has done things that are worth it.

Сегодня 23.04.2026, я открываю браузер и вижу, что моя строка и ярлыки находятся сверху, а не в центре(1 скриншот). Вчера 22.04.2026 все было хорошо, я покажу на 2 скрине как это должно выглядеть. Хочу заметить что у меня включена функция Handoff и она мне удобна, но мне неприятно видеть блок с ярлыками и строкой не по центру. Я использую тему ffultima, скажу еще раз, вчера все было нормально. Версия фаерфаокса у меня - firefox developer edition

I tried to use a ftp link setting firefox as the default ftp app, not realizing firefox no longer supports ftp. I am unable to reset the default app and can't find the setting to do so. I downloaded filezilla and wish to set it to be the default app for ftp. Can someone help me with this? Before anyone suggests it, resetting firefox to default settings is not an option.

I want to avoid any 'ai assist' searches because I do not find their summaries accurate or valuable enough to be worth the environmental impact they consume. I know my web browser searches are not under the control of firefox, but for privacy and security I kill cookies when I end browsing sessions. So I am not staying logged in to search engines when I finish my sessions, and setting my preferences to 'no ai assist' on DDG doesn't last session to session because the search engine defaults to 'ai assist' searches now, as does google.

Are there any search engines that do not use ai?

Has anyone written an extension/add-on to FF that would add 'minus ai' to all my searches no matter what browser I use? Or otherwise indicate to search engines that I do not want ai-assisted summaries period?

We've got various privacy options built into FF--this is why it is my preference always--and it would be LOVELY to have a 'no ai' option too.

Good morning, I'm running Firefox Developer Edition 143.0b6 on Linux Mint 22.1. A couple of weeks ago I noticed that when moving tabs on the left-hand side they'll instantly get locked into an inscrutable and seemingly impossible to fix "pinned mode". Is there a way to turn this off? It is driving me crazy. I've looked through Settings > General > Tabs and about:config and didn't see anything relevant. If anyone has run into this or knows a workaround, I’d be grateful to hear it.

I installed Firefox Developer Edition and I am having the following issues, whenever I go to Indeed and I go to a job posting the browser opens up additional tabs without my permission or me doing so. Also the browser does the same in Canvas when I go to my course the browser automatically opens up new tabs without my permission and also me doing so. The Firefox Developer Edition browser update is Firefox Developer Edition is up to date 152.0b7 (64 bit). The following extensions are installed AdBlocker Ultimate, FoxyProxy Basic, Ghostery AdBlocker For Privacy, Malwarebytes Browser Guard, Privacy Badger, and UBlock Origin. This behavior got super annoying and I don't know how to fix it. Any help on how to fix this would be appreciated. My operating system is Windows 11.

So, forgive me, I'm a little frustrated right now, but I needed to move an Open Tab to it's own window, without the use of my mouse (yes, it's having issues right now), but: I used to do this by tabbing to the TAB in question and pressing <Shift> F10, which opened a context menu with a Move To sub-menu. Now the menu didn't have that option. see pic below. ...Yes, I was able to do the same via, File | New Window, and coping the address to it with Windows cut/paste and <Alt><Tab>. Still I would like to know how to get to the TAB context menu option without the mouse.

Moderator note: this question has been edited to correct the formatting.

Why Firefox lacks having right click option (context menu) for multiple search engines like Chrome (Chromium browsers) and Edge has somewhat "Chrome-like omnibar in Mozilla Firefox"?

If I am using a certain search engine as default but don't use it all the time or want to use another without changing the default search engine or want to search a term or sentence via any search engine, then Firefox has no such option or addons (yes, checked thoroughly for latter).

Opera has from day one, Vivaldi also has it, Chrome allows it via extensions, Edge does via addons, Brave as chrome does via addons, Naver Whale (South Korean browser, underrated, seriously) has options to put more than 1 search engine for search results.

Adding images below for reference.

Why Firefox is seriously so old and outdated and nowhere close to standards of 2024 and 2025?

Somebody made a post 10 years ago around 2014 🤯🤯🤯 and Firefox, as usual went their way as they are doing now.

I am using Firefox Developer Edition version 154.0b5 (latest according to settings) and when I try double clicking or use ctrl + A, the url won't be selected (or parts of it if I try something selecting something specific). Double clicking doesn't work at all.

Is this a bug?
