Firefox Community Forum

Dear Technical Support,

I'd like to report a problem which affects the rendering of websites in Firefox with a HiDPI monitor.

I'm having issues with the text and graphics of web pages, that are often mismatched or misaligned, with text being too large compared to graphical elements. See the enclosed pictures for an example; as you can see, this happens also on your website. Also, I've noted that pages (and plugins) appear to be "shrinked" as opposed to when viewed on Chrome, where they are shown to their true size.

Setting ui.textScaleFactor=100 and tweaking with layout.css.devPixelsPerPx did not change much. I must admit that I find this behavior quite strange, since HiDPI monitors have been around for more than a decade, and especially considering that this did not impact my experience with Firefox on Windows, using the same monitor and machine.

I hope to find an effective solution to this problem and look forward to your reply. Please let me know if I can be of any help in this matter.

Best regards, Federico

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.

Twice in the past 2-3 weeks I have had to restart the computer, Linux Mint 21.2 Firefox 124(when updated in the past couple of days), due to the mouse freezing up and not being able to move the mouse on the screen. That's not the current problem, but it might help direct things to the final solution.

After the most recent reboot last night now I'm having a rather problem. The up/down arrow keys are no longer scroll me up and down a webpage like they always have in the past. Instead of doing smooth scrolling like they always use to, now they are scrolling me up and down the links on a web page. For example, if I were to be on youtube it would first want to scroll me down the left side links before taking me through each and every video link, when the page goes to load in more videos than it wants to go back and scroll me down the left side links again. It acts like it is taking me through the html code, line by line, instead of scrolling me smoothly down the webpage. The only way I can scroll smoothly down the webpage is to use the mouse on the scrollbar on the right side. It does this both in normal mode and in Troubleshooting Mode.

I have checked and beret scrolling is false as well as beret_shortcut. Use autoscrolling, use smooth scrolling, show scrollbars and always underline links are all clicked on. Always use the cursor keys to navigate within pages is unclicked. I have tried different changes between clicking on and unclicking those options with no change being noticed.

How can I get this back to the way it used to run?

I am a UK user and have just installed and started to use Firefox on a brand new Linux Mint installation. As I am transferring from a Windows/Chrome environment, there is a lot of setting up to do. Firefox transferred most of the chrome info for me, and so I was able to get up and running with bookmarks and logins quite quickly. However, there is one problem that I can't seem to resolve.

I have been able to set up my credit card details, and these are prompted when needed, BUT, Firefox will not remember my name, email, phone or address. Thus for every form that I have to fill, I have to enter these details, again and again (and again).

I have looked at settings and see that the 'Autofill Address' option is not present (see attachment).

I have followed and implemented the fix proposed elsewhere, to update/add GB as an address format. This has not made a difference.

Can anyone please help.

Regards,

Mark

I don't know if that was supposed to look like, but when rendering MathML in Firefox 124.0.1 when one uses "mtable" element the browser adds very huge gaps around.

The included image shows output for the following code:

<math display="block">

 <mfrac>
   <mi>A</mi>
   <mn>2</mn>
 </mfrac>
 <mo>=</mo>
 <mrow>
 <mo> ( </mo>

I have just encountered another of Mozilla's unwanted, unneeded changes.The three simple little characters that almost all programs show in the upper right hand corner on the screen. These are long standing and well understood icons that were easy to use to manage your windows. Need to switch between program windows? Press the - key. Need to enlarge the screen to its fullest, press the open box, finished working with this program/screen, just click the x-box. Pressing the "open box" would adjust the screen so you could use the cursor to make the screen the siz you needed.

It's not just that these features work and are understood, Mozilla makes changes with no explanation, no other options for doing the same thing (exception: I can close the window with File> Exit (or Close)

I just spent a week getting Thunderbird115+ to "work" and now I have to figure out how to recreate what I've lost on Firefox? Like other people seeking support have said, I want the Firefox I know back.

These websites won't play audio or video in Firefox 110.0.1, they work in Chrome 110.0.5481.177

https://www.vrt.be/vrtnu/livestream/audio/stubru/ When I click the Play button I get an error "Oops, something went wrong, error code 200" which seems to be a general error code. In Chrome the music starts playing instantly.

https://f1tv.formula1.com/ I have a subscription but video won't play. I can press the Play button, sometimes I see a preloader but the screen stays black, no audio or video. In Chrome the content just starts playing, be it live or recorded content.

Steps I took to get audio/video working inb Firefox, but to no avail:

run above websites in private tabs download Firefox again and run it from its folder in Downloads start Firefox in Troubelshoot mode start Firefox in Troubleshoot mode and Refresh Firefox disabled / enabled Plugin Widevine Content Decryption Module provided by Google Inc disabled / enabled Play DRM-controlled content in Settings disabled / enabled Enhanced Tracking protection disablde / enabled allow media autoplay

In other discussions it was opted to remove the PulseAudio config by running the below command and rebooting rm ~/.config/pulse/*

Any help to get this working again would be greatly appreciated!

Sync is a nightmare. It is so unintuitive! What exactly would be wrong with having separate Export and Import buttons for each of Settings, Addons, Tabs, History, Bookmarks, etc? I have a desktop box and a newer laptop I wanted to get up to date. I pressed the Sync button on the desktop ... By the way, there`s a link below that reads "Connect another device" ... Connect where? Someone is designing these interfaces who has absolutely zero imagination. Anyways, I signed off, moved the ethernet cable to my laptop, signed in, pressed Sync, and voila!, I got my Bookmarks, at least. But I have no idea how to get my tabs and windows. I tried with a "download link" something or other, but it seemed to assume I was sync-ing to a phone, and didn`t work. Any way to get my tabs?

Hi all :)

From a fresh Linux Debian Bullseye I try to connect to a local machine with Firefox (v97 64-bits) by its hostname (avahi server with default domain "local") with the port 6180 bound to a remote web service port (61 is the distant machine IP and 80 is the forwarded port).

When I want to open this URL : http://bionic.local:6180/ FF displays "We can't find this site ... Unable to connect to server at bionic.local ... check your network connection and firewall"

BUT ping bionic.local works perfectly and resolve the good IP address from the Chromium navigator the same URL works without a problem, I can open the distant web site.

This workaround works : add a static resolution in the /etc/hosts file : 192.168.0.71 bionic bionic.local => so FF works in the expected way for now ! But as I said this a workaround and a bad solution.

I supposed too the port was blocked because I accessed an unusual port. So I tried this without success.

How the hell make that FF v97 allows me to use an unusual port ? Or is it bound to the domain "local" which is no more accepted by FF ?

Thank you in advance for your help. With adelphity, lnj

How to do

Firefox 120.0 on openSUSE Tumbleweed.

Google Maps (https://www.google.com/maps) results in CPU being pegged at 100%. No other tabs open. All I have to do is load the URL and do nothing else. This behavior is repeatable. CPU stays at 100% until tab is closed or browser is shut down. Sometimes the browser will hang and its PID has to be killed.

Offending process:

Hi! I'm sorry if this is not the correct topic for this question, but I'm having huge trouble surfing the community forums of Mozilla. Could you please help me to understand what is the correct community forum to talk with other users about Firefox Relay service? Or a generic Mozilla community forum...

I need the community's help for technical purposes with the mentioned service.

Thank you very much for your patience. Noè.

The problem is : Some of the time FF just records 0 bytes file and says nothing. I suspect that FF inspect the URL of the links and discard ( perhaps for security reason ) ones that do not begin with HTTP.

The bypass is : One has to copy the link and insert in in the new page of FF.

The solution would be to change FF code.

Thank you.

Hello all,

For some reason, I can no longer upload or download files, with the pop-up window failing to appear entirely. I can upload folders through, for example, Dropbox or Google Drive, but individual files don't work.

I've reset my browser, uninstalled and reinstalled it, opened it in troubleshooting mode, disabled enhanced tracking protection, but nothing seemed to work. I've tested another browser, and I was able to upload and download files just fine.

Is there anything I can do to fix this? I'm on Ubuntu 22.04 using Firefox 107.0.1.

If i am on amazon for example and an item has more than 1 option, Honey presents drop down selection box so you can choose which one to drop list The issue is the drop down box never opens when you click on it, doesn't matter where on it you click, it wont open. I have cleared cache, reinstalled honey and nothing helps. I have multiple desktop pc's all running tumbleweed and they all have this issue. If i load Chromium that works ok, but i use Firefox and not Chromium. I'm using openSuse Tumbleweed (latest update).

I am on arch linux running wayland, and whenever I visit some webpages (example reddit, github) some character are displayed incorrectly: spaces are incredibly large and numbers appear as . or , or other random punctuation or don't appear at all

1, Strange formatting of <B> inside <PRE>. When using the default monospace font inside a <PRE> element, adding <B> elements disrupts character spacing. A screen shot is attached. "wheat" & "purple" are the colors. They are set in a CSS file. Here is the source HTML:

<PRE class="white">

<This character spacing disruption is surely a bug.>

<2, Unexpected formatting of bogus <D> element.> elements to (bogus) <D> elements in the source HTML. The result? The colors were retained and the characters became aligned.>

<What do you think of 1 & 2? Can you test in other browsers -- I can't.>

<Thanks for Your Thoughts,> Mark.

Firefox 122 can't display at least one site I found today. www.dominos.ca. Only part of the page loads many elements are missing. I have disabled all extensions and the problem still exists. This page never gave me problems before this latest Firefox.

Whenever I try to open Firefox, it takes about 25 seconds to boot. This behavior can be observed both with all the extensions running and in safe mode. The link to the profiles are shared below.

With extensions: https://share.firefox.dev/3riMPQZ In safe mode: https://share.firefox.dev/3OadE31

I have been noticing this for a few months now. Firefox works just fine after wasting ~25 seconds initially. I have also reinstalled Firefox multiple times. Right after the installation, the boot-up can be very fast (less than 1 second). However, after using Firefox for a few hours, the problem comes back.

I am not well-versed in reading Firefox profiler reports. So, please help me figure out what's actually happening in those ~25 seconds.
