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?

Firefox 136.0.1, Linux 6.8.0-55, have set Okular as default pdf application, however Firefox will not open pdf file when downloaded nor will it open the file when selecting Open File from the Download Icon on the toolbar. Only was I can get to file is to select Show in Folder option and open from within Dolphin.

I am using the apt version of firefox v125.0.2 (64-bit). I do not have a dedicated GPU - I use my intel core's internal gpu only Intel Corporation HD Graphics 620 (rev 02).

I used to play this game named narrow.one, which before I reinstalled the mentioned libraries, was working fine except for crashing a few times. I thought these libraries were causing some issue, so I tried reinstalling them.

I reinstalled the libraries using: `sudo apt install --reinstall --fix-missing libgl1* libegl*`

After installation, I start getting that error. So, I tried reinstalling firefox (using the same command), and then restarting the laptop - but of no use. Chrome seems to be running WebGL, including the game.

In firefox, on the https://get.webgl.org/ page, I see Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card.

After that, I also tried reinstalling `libopengl0` and `libglu1-mesa` and `intel-microcode`, but of no use. Running although, `sudo intel_gpu_top` and then chrome, it seems that the GPU is in use by chrome as well.

I then go to about:support. It shows me the images I have attached. Reading the logs, there several `blocklisted` values in `Decision Log` section. I suspect that's the cause of this issue, but then I don't know how can I un-blocklist the blocklisted things, and even after that, why does Chrome runs webgl if these are blocklisted?

Running `glxinfo -B`, I get the following: `name of display: :0 display: :0 screen: 0 direct rendering: Yes Extended renderer info (GLX_MESA_query_renderer):

   Vendor: Intel (0x8086)

I do not know much about OpenGL, but reading the above stuff, I suppose my GPU is in use and also has a compatible driver (although I am not sure).

Also, running `glxdemo`, `glxheads`, and `glxgears` seems to be rendering stuff.

Should I reinstall firefox after purging it first? Please help.

Thanks!

Hi,

I installed thunderbird in a new computer via flatpak. The computer is running PopOS 22.04 and the current Thunderbird version is 128.0esr.

I don't know if this happened after the last update from 127 to 128 or was like this before, but on the compose window all the menus and buttons on the top row are completeley invisible, white on white (if I hover over them, then they are slightly visible). See the first 2 images.

The main window is OK and everything is readable (see 3rd image).

I don't know how to change these colors.

Any help will be appreciated.

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.

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)

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

This issue is happening with every newly installed add-on, but not with add-ons installed on or before Aug 3, 2024. The add-ons are installed via addons.mozilla.org. To rule out the possibility that it's happening only with specific add-ons, I also installed one of the random recommendations on that page, Augmented Steam which has 54,248 users, and it happens with that one as well.

I'll click Enable, but the prompt appears every time I restart Firefox.

What I've tried (with a restart after each attempt):

• Clear the startup cache
• Delete extensions.json
• Delete compatibility.ini
• Via about:config deleted extensions.databaseSchema and extensions.getAddons.databaseSchema
• Excluded Add-ons from syncing

I've noticed the following in extensions.json for each of the recent add-ons after restart:

• syncGUID changes to presumably random new value
• active changes from true to false
• userDisabled changes from false to true
• seen changes from true to false

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.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to nrega.nic.in because this website requires a secure connection.

What can you do about it?

nrega.nic.in has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

Probably nothing, since it’s likely there’s a problem with the site itself.

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?

Every time I open Firefox after closing it, I get the message below. I can click the button to restore session and it works every time. With each update, I hope to never see this message again, but after installing a new version on Ubuntu today, I see the same familiar message. This is not linked to a computer, or an operating system because I've seen this on both Ubuntu and Mac. If Firefox could literally just click the button that would be awesome.

Sorry. We’re having trouble getting your pages back.

We are having trouble restoring your last browsing session. Select Restore Session to try again.

After installing thunderbird, It takes me hours to figure out that my fonts are too small because of one value in Settings > General > Language & Fonts > Fonts > Advanced > Fonts for Other writing systems gives a too small number.

It seems insane and I don't think users can easily get there. Maybe some users want to set different fonts for different languages and the "Fonts for ..." is for them. However, for most users who just want to change their font size, I don't think it's a good experience to going so deep and find an option in the loooong "Fonts for ..." list.

So please give users a simple option where I can just set my font size without such pain.

I know there's a font size option in TB menu but it doesn't work as expected. In my case, the font size shown in TB menu is 16 while the font size of my plain text emails is 12. And 1. email font sizes will change to TB menu size as long as TB menu font size is not 16. For example, when changing TB menu font size 15 -> 16 -> 17, email text just suddenly goes from 15 to as small as 12, and then from 12 to 17. 2. email font size seems changing with the TB menu font size. However, email text font size will go back to what it was when open another email.

I am using Firefox v140.0.1 Snap on Kubuntu 25.04, Kernel 6.14. Since the Firefox update in the past couple days, the mouse cursor has started appearing huge and slightly blurry (as though the image is scaled up) in Firefox and nowhere else. The size is visually annoying, and occasionally difficult to know exactly where I'm clicking (trying to move the caret in a text box for example). It also appears to be a different style from the main desktop cursor, the shape and color are ever so slightly different, but this may already have been the case and I simply didn't notice because of the previously small size. Firefox doesn't have its own built in cursor settings that I can find, nor obey the system cursor settings. I have a high DPI display so perhaps it is being over-compensated for? e.g. both the system and Firefox are scaling the cursor up, assuming the other hasn't done it already, resulting in a cursor that's too big.

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!

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.

Hi, my Machine updated from 140.0.4 to 141.0 since then I cannot start up Firefox anymore. On startup after a short pause the Crash Reporter shows up - interestingly the Crash Reporter may enter a endless loop and opens up multiple times. While that the CPU load is at 100%. I tried

• `firefox --safe-mode`
• `firefox --ProfileManager`

as well, for those I get the same behavior. I tried downgrading to 140.0.4 - after that a profile dialog shows up which tells me that a new profile needs to be created due to a downgrade. After that Firefox comes up fine with the new vanilla profile. IF Firefox updates to 141.0 (in background) the next startup with the vanilla profile doesn't work gain. Which brings me back to the initial problem.

Workaround for now:

• download 140.0.4
• create a fresh profile
• immediately disable auto update
• live with the empty profile

My environment:

• Linux Debian 12 on x86_64
• KDE Plasma
• nvidia drivers installed
• I am using Firefox from `https://download-installer.cdn.mozilla.net/pub/firefox/releases`

I am using Firefox 127 on Ubuntu.

When I press the Control key, I often lose focus in the window I am currently viewing. This is annoying as it prevents me from copy-pasting for example.

Sometimes the focus is back when I release Control, sometimes it is lost and I have to click again on the text field. It does not happen on all websites, for example support.mozilla.org works well, but it happens on duckduckgo or overleaf.

It does not seem to be the same as existing issues such as [the "show mouse when press Ctrl" of Ubuntu] (it is disabled) or an addon (the problem still happens in safe mode).

In case it is useful, when I press Control the tab bar background goes slightly darker, see attached images.

Thanks for your help :) Nicolas
