FF bug (?) (my own tests), Chrome works as expected, was also gemini ai discussed.:

 Why for the following css rule (new FF):
 header:has(~ noscript) ~ * div[class*="-slider"] {width: calc(var(--number-of-slides) * 100%);}
 the --number-of-slides is defined and visible:
 header:has(~ noscript) ~ * div[class*="-slider"] {--number-of-slides: 1}
 but this one isn't at all:
 header:has(~ noscript:has([value="1"])) ~ * div[class*="-slider"] {--number-of-slides: 1}
 And all remembering that in the noscript there is direct descendant having value="1"

As mentioned it works as expected (so average person naturally may think it sould) well for Chrome - noscript is visible, js disabled, controls are visible. Sophisticated use case of :has() but it sort of "has right" to happen.

When I open Firefox and call up bing maps , it starts to load the page , then Firefox crashes . Has been doing this for several firefox versions . Looking at the crash report , I always get "The debug symbols are missing for firefox. Please install firefox-dbg." but I can't find firefox-dbg to load

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.

I updated firefox through apt, and since then, have not been able to log into twitch I am on ubuntu 24

apt list --installed | grep firefox firefox/mozilla,now 144.0.2~build1 amd64 [installed]

Attempting to log in returns the generic "Your browser is not currently supported"

I'm running 145.0.2 on Mint Linux and Windows 11...

Like many other users, I have an issue in which roughly half of the icons representing bookmarks on my Bookmarks Toolbar have been replaced by the black+and+white icon of a globe. The links work, but because most of them are now the same, it means I have to hover over them to make sure I click on the link I want.

I've tried: Exporting all my bookmarks to HTML; deleting all bookmarks; re-importing Deleting the "favicons.sqlite" database and letting Firefox recreate it Creating a new Profile and importing all my bookmarks "fresh" in to there

Not only does none of this seem to work, the results are actually inconsistent.

This problem has been kicking around for years - certainly for many major releases of the browser. I understand that there could be deep/complicated issues such as a corrupt user profile, for example...

Unfortunately, however, there does not appear to be any consistent or reliable effective advice on how to fix this issue... and nothing I try seems to resolve the problem.

I'd be very grateful for any recommendations on a reliable repair for this issue.

But I'd also be grateful for suggestions as to how we might go about suggesting to the devs that this long-running bug is overdue a permanent fix.

Thanks in hope.

After an update of ubuntu 22 on my computer, Firefox does not render properly (see the screenshot of my desktop). I have tried to reinstall it but it continues to happen. All the other programs works fine, it is only firefox.

My system is: Ubuntu 22.04.2 LTS Processor: AMD Rysen 5 3600 6 core procesor x 12 Graphics: AMD Radeon rx 5500 tx

Thanks.

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!

After updating to version 121, the cursor theme, while having it on the window, changes from the default one (Breeze) to Adwaita while also getting like 2x bigger. How do I change it back to default theme and size?

Hi. I was just looking at Google Photos on both Firefox and Chrome. Chrome had a bigger picture because the window had only the tabs bar and the address bar, and Firefox has an additional title bar. I was wondering if it would be possible to remove the title bar so the picture on both browsers were the same size?

I moved to the Firefox flatpack after the Debian version couldn't display the code inspector/ web developer tools anymore (it was blank amid other likely javascript-based rendering errors). I only include this context in case some one else has the issue and searches for it.

I want to sync all my tabs from the Debian version to the flatpack version and similar to this solved issue I cannot access those tabs from the firefox view. However I am also unable to access these tabs from the sidebar. I am only able to access these tabs from the account menu but this would have me open each tab individually which is not feasible for me.

Is there a way to fix the "Check your internet connection If you’re using a firewall or proxy, check that Firefox has permission to access the web." error that comes up in both the Tabs from other devices sidebar and Firefox View menu?

Since this week I have been unable to access flightradar24 web site due to a problem with WebGL. It tells me that I need a compatible browser e.g. Firefox

I am running Linux Mint 21.3 Cinnamon on and I7 processor with a NVIDIA Corporation GK208B [GeForce GT 710] graphics card.

I have edited the about:config file as follows:

webgl.force_enabled TRUE

but noted a collection of failed messages as shown on the attached screen shot.

This web site is still accessible using chromium on the same computer, suggesting that there isn't a hardware problem.

Thanks

Video on some websites is choppy after updating to a newer version of Firefox (115.8.0esr). I have attempted to upload a video of the problem but it seems only still images are allowed and this doesn't illustrate the problem. An example website where this occurs is https://www.fiat.it but there are plenty of other examples. It looks as if the playback is jumping forwards and backwards between frames. Strangely Youtube videos seem OK.

Some information which may be of use

OS: OpenSuse Leap 15.5 HW: Dell Precision 7510 with Nvidia Quadro M2000M video card and driver version 550.54.14

I have also noticed that when starting Firefox from the command line I see frequent messages like

Sandbox: attempt to open unexpected file /sys/devices/system/cpu/cpu0/cache/index2/size Sandbox: attempt to open unexpected file /sys/devices/system/cpu/cpu0/cache/index3/size Sandbox: attempt to open unexpected file /sys/devices/system/cpu/present Sandbox: attempt to open unexpected file /sys/devices/system/cpu Sandbox: unexpected multiple open of file /proc/cpuinfo

Probably not relevant but I included it just in case it is useful

Any help you can offer with debugging would be much appreciated, thanks

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

Does anyone know how to configure Firefox to stop the annoying google log-in pop-up? I've seen others ask the same question, but I have not seen any functional answers. I've never had a google account, for anything. I don't get the pop-up with other browsers, like Falcon or Brave. It's just a problem on Firefox. I appreciate you help!

Would like to test nightly builds of Firefox - how best to get started?

I am a user of Ubuntu and interested in testing the Firefox Nightly via snapstore.

Any pointers helpful.

I see where other people have posed this question but the procedure offered is not available to me.

I am using Firefox (Flatpak) version 121.0 on an Ubuntu 22.04 laptop.

On installing a new extension I should either see the extension's icon on my toolbar or else have a clear means of adding it. I have neither.

Clicking on the jigsaw icon in the toolbar, I get migrated to the about:addons page. On clicking the Extensions tab, I get the screen listing all installed extensions. Each extension has a ... icon beside it. But when I click on this, there is no "Pin To Toolbar" option.

What is wrong here ?

Since about 13:00 GMT yesterday, Firefox could not load or display the Hostinger h-panel. It sometimes partially and sometimes completely displays all the page content. But all the controls are dead. Firefox seems to be very busy doing something. I told Hostinger and they spent some time looking into the problem. They got Firefox to load the h-panel but said that it was vastly slower than other browsers in doing so. With me, Firefox still stops doing anything once the content is loaded and ALL controls on the page are still dead. When closing Firefox in this state, there is considerable delay before the window actually closes.

I thought that perhaps Hostinger had done an update that called in some proprietary JavaScript extensions that Firefox couldn't handle. I get the impression that in trying to display the h-panel pages, Firefox is trying to acquire some content from an external site, as requested somewhere within the HTML/JavaScript source code.

Any ideas? robert_john.morton@yahoo.com

I'm setting up a user on a new computer. I've exported her bookmarks from her old computer. On the new computer I go to Bookmarks > Manage Bookmarks > (select bookmarks toolbar) > Import and Backup > Import bookmarks from HTML. I browse to my folder containing the bookmarks.html file, Open it, and nothing.

I've tried all the suggestions I can find. Places Database Verify Integrity gives me: > Task: checkIntegrity + The places.sqlite database is sane + The favicons.sqlite database is sane > Task: checkCoherence + The database is coherent etc. Opening the bookmarks.html file shows a list of bookmarks. That file is not empty.

This shouldn't be this hard. How do I accomplish this?

Subject: Urgent Assistance Needed with Certificate Installation

Dear Team,

I hope this message finds you well. I am in urgent need of assistance regarding a Linux-based system where we have the Firefox browser installed. I need to establish a secure connection with one of my servers, which requires the installation of a certificate.

However, I am unable to locate the certificate export button in the certificate view or anywhere else in the browser. I have tried several methods without success.

Could you please help me with this issue as soon as possible? Your guidance would be greatly appreciated.

Thank you very much!

Best regards, Kishor
