Firefox Support Forum

Hello,

I have encountered a recurring issue specifically with Firefox where SVG images fail to display unless a pixel-defined height attribute is explicitly set. This behavior contrasts with other browsers, which handle SVG scaling seamlessly, typically adapting to the specified width or inheriting dimensions from parent elements.

During our website development, primarily through Elementor and leveraging Flexbox in a WordPress environment, this discrepancy becomes evident. The issue persists exclusively in Firefox, confirmed through extensive testing across various browsers and OS's with multiple SVG files and sites.

For diagnostic purposes, I recommend conducting controlled tests with SVG images embedded with our current setup. Set the SVGs to 100% width without defining their height and observe how they render in Firefox compared to other browsers. This should help ascertain whether the behavior in Firefox is anomalous.

I am assuming it may be with the way the markup of the SVG is rendered as it doesn't happen with all SVGs, however, other browsers appear to fix or override whatever is getting in the way from rendering...it is a strange issue.

I have included two images as an example. As you can see in the first image, the SVG isn't rendering (in Firefox) , but does render in Chrome/Safari. It only works when I define a height in px value on Firefox.

Please let me know if further information is required or if any specific steps need to be undertaken to address this issue.

Thank you.

I have a well hidden web server that uses HTTP. I need to download files from that server. After the newest update, Firefox now gives a warning about the website and on that warning is a button to "Allow Download". However when I click on that button, the file that gets downloaded IS NOT the file that I was initially attempting to download. It looks like it is a copy of the web page that was being displayed at the time. I noticed this behavior at work. I went home and used Firefox to connect to the server and everything connected and downloaded correctly. I went to see what version of Firefox was running. It was 124.0.2 and there was a button saying "Update Firefox". I clicked that button. My home Firefox updated to 125.01 and my home version of Firefox now also downloads the wrong file.

This happens on other websites as well: https://www.exploit-db.com/

Can you help?

For some time now, Firefox has been unable to display quotes on Yahoo Finance; for example:

https://finance.yahoo.com/quote/MSFT/

The space where the price history graph for MSFT should be is blank except for a message saying "Loading chart for MSFT". The chart never loads. Sometimes Firefox issues a message saying that the site is "slowing down Firefox".

This happens for *any* quote, no matter what the ticker symbol.

I have tried running Firefox with a new profile, running in a private window, and running in Troubleshooting mode; the behavior remains the same. Clearing cookies and changing the tracking protection setting has no effect.

Oddly enough, when I attempted to report this page as not working, I couldn't submit my report (the Send button did nothing -- though this feature works for other sites).

Have others here experienced the same problem; and if so, is there a known cause/resolution?

Thanks in advance for any help.

I installed an OBS plug-in for a virtual camera so that I could film my screen and pretend it's a webcam. I was able to use the virtual camera or my webcam on spelltable.com by selecting either from the dropdown "allow" menu. One day, I was no longer able to select my webcam. I could only select the obs virtual camera. I switched to MS Edge which worked as normal. I've uninstalled OBS and all plug-ins. Same result I've reinstalled firefox. Same result. I've been using MS Edge for websites that need my camera.

Hi there,

About 4 days ago, hotmail suddenly stopped loading on Firefox (though I can still access it on Safari). I've tried clearing my cache and add-ons, etc. I've googled a ton and tried all the things I can find to try, but nothing is working. I am by no means a tech person and so I'm out of ideas and need some help. I know I can use Safari, but I really hate using it and prefer Firefox. Any ideas on what to do? I am using a MacBook Pro - Sonoma 14.4.1

Thank you so much! Jocelyn Pascall

When using picture in picture on Prime Video, my subtitles aren't showing up in the window, but instead on the original page, despite prime video being one of the original supported websites. Any ideas on how to fix?

I have always been able to connect with Navy Federal Credit Union for my banking until a few days ago. Every time I click on the accounts shortcut I get the FAILED TO CONNECT window. I can open my e-mail and ALL other websites. I can connect with Goggle but I've always preferred and used Firefox. I have used Firefox as my main browser for many many years. What is the problem??

When I turn off the windows animations in Windows 10 the font on Twitter.com changes somewhat. I believe it is altering the character spacing/scaling.

I have not had this behavior on other browsers (Brave, Edge, Chrome & OperaGX tested). I have not noticed this on other websites, but I also haven't really looked.

Windows version 22H2 (OS Build 19045.4291) Firefox version 124.0.2

Images provided are with them off, then on

Steps to recreate 1. Load a tweet (tweet in the images: https://twitter.com/FedeItaliano76/status/1779855670432408011) 2. Turn off window animations (settings->display->show animations in windows->Off) 3. Reload the Tweet

This is not a critical issue for me, but I think it's worth mentioning

Anyone experiencing issue with YouTube on Firefox - I am not able to select suggestions on YouTube search using up/down arrow keys - On Ubuntu 22.04 - Firefox 124.0.2

Anyone else had the problem of not being able to sign in to the Amazon Parent Dashboard via Firefox? But works on Chrome. Same on desktop and android versions of Firefox.

Amazon chat support not helpful and just told me to use Chrome!

Hello,

First time posting here, so I'm hoping that someone can help me out.

I'm encountering a very odd issue on my Macbook Pro running MacOS Sonoma 14.4. I am unable to access two sites – allrecipes.com, and seriouseats.com on my home WiFi network on the Macbook.

These sites work on other browsers (tested on Safari and Chrome), and they also work on my iPhone.

Oddly, when I went to work and tried to access these sites via WiFi using Firefox, I was able to.

I am unsure what the problem is – the ability to access these sites on Safari, Chrome, and my iPhone at home suggests that it's not a network issue. I haven't encountered this issue with any other sites.

I am attaching three screenshots 1) The error message that I'm seeing for allrecipes when I attempt to access the site 2) The security tab which shows that the connection is unencrypted for allrecipes (home network) 3) The security tab showing that the connection is encrypted for alrecipes (work network)

Thanks

I have:

125.0 (64-bit) Mozilla Firefox for Ubuntu canonical - 1.0

Video on Facebook plays without sound. The video plays, I see the image normally, but no sound. Video on Youtube works perfectly.

Fresh install without addons or plugins. Switching to "Troubleshoot mode" does not change anything. Youtube with sound, Facebook without sound.

Any ideas where to look?

I am having a new (to me) problem logging in to Flickr using Firefox on my laptop (running Windows). After supplying the requested email and password at log in, I was prompted to enter a verification code that was sent to my account email address. After promptly entering the verification code, I was returned to the original log in page. There was no error message to indicate that either the address, password, or verification code were incorrect or that anything else had gone awry. I was simply not logged in. I repeated this process a few more times with no change.

Then I tried two other browsers (same laptop) and logged in sucessfully without even having a prompt for verification code from Flickr. I also have access to the account through the Flickr app on my phone. I am not sure then what Flickr is encountering with Firefox in particular. Any suggestions? Thank you.

When I open github it loads incorrectly as shown in the picture, after I press F5 to reload the site load fine. I have tried deleting cookies and I am using any ad-blocker. Any help? Thanks.

I have a website that I host. It is behind a proxy. It is a resolvable FQDN with DNS hosted by a major provider. The issue is when I browse to it via Firefox 124 it eventually errors out with connection reset, however if I open a private window it goes right there. I have tested other browsers and it works fine with them (Chrome, Safari, Vivaldi). I thought maybe it was plugins so I tried shutting off plugins one by one restarting after each one and that did not help. I tried in safe mode and could not get there. So I backed up my bookmarks and wiped out the directory and all for Firefox and tried on a fresh directory and that did not work except in private window mode.

Hi there, my name is Alvimutmex. Every time a webpage loads with the Mozilla browser, a "not supported" message appears. Upon examining the settings, I found that Mozilla has to be updated. Would you kindly assist me with updating Mozilla? For example, I receive an error notification when I try to open (https://pdfmedicalbooks.com/).

I am experiencing more and more pages suddenly not working on numerous websites. I am working with an Imac running OS 10.9.5. I am experiencing problems with Firefox, Chrome and Safari and am having to revert to my Microsoft Lap top for a working browser.

Any ideas on this???

For about a week now YouTube doesn't display correctly. No content shows. I can open private browsing and works fine. Also works fine on other browsers just not Firefox.

I'm on an iMac running Firefox version 124.0.2 and I've tried disabling all add-ons but nothing has changed to the browser so shouldn't cause any issues.

Any help?
