Firefox Community Forum

I've got my "homepage and new windows" setting set up with several "ext+container links so that my selected websites open in their respective containers : e.g. ext+container:name=Personal&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor

I open facebook in 2 seperate containers so that I can maintain 2 seperate personalities under facebook - e.g. I am a group admin within one, just a group member in another.

I have 2 urls defined in my "homepage and new windows" setting for these :

ext+container:name=Personal&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor ext+container:name=Facebook&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor

This was working fine without any issues. My sites opened up when I started my web browser and everything.

Recently, firefox has started up but my container tabs do not load automatically, I am getting a confirmation (I will post a screen capture as a comment).

Is there a way to turn this off and just open the tabs without a confirmation?

Hi, I'm not sure if this is a bug, or me not using FF properly.

I want Firefox in general to ask me, which profile to use when started. So in the Profile-Manager, I removed the checkbox for "Use selected profile without asking as startup".

Now, I wanted to create a shortcut for a specific profile, so I tried running `firefox -P "myProfile"` or even `firefox -p "/path/to/myProfile"`. In both cases I get the window asking me which profile to use.

Debian 12.6 - SwayWM Firefox 128.0 (64-bit)

I am using Linux Mint with Firefox 127.0.2 (64-Bit)

In Preferences Applications, setting

 CSV-Dokument      to    open with firefox

opens edless new firefox Tabs - so I had to kill firefox. (setting CSV-Dokument to open with OpenOffice works fine. But this is not what I want.)

In Preferences Applications, I found further CSV types: application/csv-Typ CSV Document (application/text) CSV Document (octet/stream) CSV Document (application/x-download) Which applications should I use for them ?

I found the file "mimeTypes.rdf". However, I am not familiar with the syntax.

Hello, in past versions of Firefox, I was able to follow the steps on this page to set a custom HTML file on my PC as my home page for new tabs: https://peterries.net/blog/firefox-ubuntu-local-file/

I have Firefox 107.0.1 now and it's not happening. When I open the browser from scratch, I see my custom home page file. But when I open a new tab, I just see a blank screen. If I then click the Home icon on the toolbar, I do see my custom HTML page, but I don't want to have to click that button for each new tab.

Right now, in my settings, I have the URL to the page set as the custom URL for the HTML fiile, like this:

file:///home/peter/Documents/homepage/peter-home-homepage.html

That works. And I also have followed the steps on that blog post to customize my /usr/lib/firefox/autoconfig.cfg and my ../firefox/defalults/pref/autoconfig.js files. That's no longer working.

Did something in a recent version change? Is this no longer supported? Thanks for any ideas!

Can’t launch Firefox 3.5.19 on Linux Ubuntu When trying to run with:

./firefox

Terminal gives the following:

./firefox-bin: error while loading shared libraries: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory

I am on endeavourOS (linux). Whenever I try to upload images for a profile picture to sites like youtube or X, the image becomes corrupted and doesn't upload correctly. It did this with whatsapp too and I had to use a separate app for it. Other posts said that disabling "privacy.resistFingerprinting" would fix it, but it's already disabled.

Attached below are an example of this bug and the contents of this image when viewed on a text editor.

My system broke during an update. Now I want to import my old Firefox userdata, but everytime I try to use the old data firefox just forces the creation of a new profile?

Is it completely impossible to recover data not created with the same firefox version?

I'm trying to migrate to the newest version of Firefox on an old installation of Fedora. I've downloaded and unpacked the installation files but can't identify the installer. All I probably need is the name, as I know how to make it executable and run it once I know what file it is.

Anthony Enzor-DeMeo wants to push way more AI onto Firefox. I originally became a Firefox user for the customizability, privacy, and security it offered in comparison to other browsers. How does Mozilla Firefox intend to maintain these features with so much AI slop? Will there continue to be versions of Firefox available without the AI components? I'm sick of having to turn off new data-stealing AI settings all the time on a browser I once trusted. I hate that I am now looking for other options.

This isn't so much a question as a complaint, I guess. Get your shit together, Firefox!!!

I am running Firefox 144.0 on kubuntu 24.04.3 LTS I have lost sound on Firefox. I have opened the same sites in Chrome and the sound is working fine. It's only in Firefox. I have tried several sites including Udemy, YouTube, and radio programs, no sound from Firefox. The problem started in the middle of a Jit.Si session. All of a sudden the sound disappeared. I thought that restart Firefox would help, then restart the computer would help. But the problem has continued. The speakers is turned on the volume is up, just not a sound from Firefox. What to do?

Hello

I use Firefox 132.0.1 under Fedora 14 Linux. Whenever I click an urls in another application (e.g. Libreoffice, Keepass...) a new tab is opened in Firefox (according to Firefox's settings), but Firefox itself does not pop up in the foreground, it remains in the background. I highly appreciate the setting 'open links in tabs instead of new windows'. But FF only comes to foreground in case I deactivate 'open links in tabs instead of new windows'. How can I prevent FF to stay in the background in case 'open links in tabs instead of new windows' is enabled?

Thank you in advance

Any advice returned by Google seems to be obsolete or only worked perhaps in older versions of Firefox. The main idea of using userChrome.css to override the default styles for Reader View does not seem to work. My userChrome.css file does work on other items though (like removing the sidebar width restriction).

Whatever advice I find via Google perhaps cites outdated CSS selectors, but current selectors do not seem to be documented anywhere by Mozilla. Moreover, I cannot find any file on my local drive named aboutReader.css when using find or grep commands in bash, those this file name is alluded to when viewing a page in Reader View and then in turn viewing source on that transformed page.

Moreover, addons that would allow me to change the colors seem to be restricted in Reader View.

It does seem like something has changed in recent Firefox updates but I can't remember when I last saw, for instance, links in dark mode Reader View that were still pink (whereas now they are blue, and impossibly dark to see, especially when you are disabling as much blue light as possible through your operating system). I need a higher contrast color for links in dark mode Reader View so I can actually see them.

I can alternatively use the Tranquility Reader addon and have custom colors, but A) that addon does not work with the Automatic Reader View addon, whereby I can always have various sites appear in some sort of "reader view" whether the native one or Tranquility Reader, and B) hitting refresh when in Reader View will defeat some soft paywalls but this does not work with, e.g., Tranquility Reader, so I still would prefer to be able to custom colors in the native Reader View feature, rather than rely on an addon.

1. Where are the current styles for Reader View even documented? 2. Is overriding them now restricted? 3. Why did the link color change from pink to blue in newer versions of Firefox (this is a terrible accessibility bug)? 4 .Where is the alluded to aboutReader.css stylesheet actually stored on my computer (it doesn't seem to be a file on the filesystem in the Firefox profiles folder, it seems more like it is embedded in the Firefox binary/executable)? 5. Will Firefox settings ever allow us to set colors specifically for Reader View (I don't mean the override settings for all web pages, particularly web pages not being rendered in Reader View ... that setting does not help in Reader View, nor would it be the desired preference for pages not in Reader View)?

Thank you.

I use Firefox-Dev(129.0b9 (64-bit)) and Firefox (128.0.3 (64-bit)) as default browsers on my Gentoo Linux system with an Intel i7. Both Firefox-Dev and Firefox crash will visiting some websites. Especially Google maps. I have a Gentoo Laptop with and i3 where I run both Firefox-Dev and Firefox and things run fine. I have more software installed on the Intel i7. Video cards ar different of course.

Hi. i have no results while doing this: https://dpaste.com/FTXPQ46ZL# No error, no screenshot. "Screenshot" flags in default state, about:policies - inactive.

Hi, I'm on Debian. In the last day I have intermittent connection problems on many websites which go away after a while. Any ideas? I'm using Quad9 for DNS but I don't know where in the chain something is going wrong
