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.

The pinned shortcuts on my newtab page have all disappeared once again. I've gone to about:config > browser.newtabpage.pinned and my shortcuts are all listed. But only blank boxes show up on the page. It will not accept a new entry when I try to enter one. It goes back to the blank white box. Why does this keep happening? Can anyone give me a Firefox for Dummies way to fix this?? Thanks!

Hello,

I added a browser extension Search by Image by Armin Sebastian some time ago and it worked just fine till recently. Now, every time I need to find some image I get the page with cute creature sitting and fishing in bucket of water with info stated: "Your search did not match any documents. Suggestions: Try different keywords." (screenshot attached). It happens every time, no matter what kind of image I'm looking for. I also added another extension Search by Image on Google by Gustavo Silva and it's the same issue.

Would really appreciate any help with it.

Thanks,

Magdalena

When the little yellow man is placed on to the map, and a direction arrow is clicked, the view just continues to spin round. Clicking on the 'X' in the top right hand corner terminates street view. This does not happen with other browsers.

My OS is Debian 12, Firefox is the latest version 115.9.1esr (64bit).

We have an electronic document management system in our company. The system is an internal system without access to the LAN. Firefox detects files downloaded from it as potentially dangerous after the last update. Is there a way to prevent files from this website from being detected as potentially dangerous?

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.

I am using Ubuntu 23.10.1 with KDE Plasma desktop environment. Since recently I've been experiencing the following problem with Firfox document viewer: after a period of inactivity, PDFs become unreadable, and seem to cumulate everything that was displayed on screen (see screenshot). Ctrl + F5 does not help, and neither does closing the window and opening a new one with a link to the file. KDE Document Viewer displays the same file correctly.

I've been using the Firefox browser, and recently when downloading files with Firefox, sometimes it prompts: .part could not be saved, because the source file could not be read. # see image #1 I'm trying to download file to disk D. But the fail tips is download .part file to disk C. Maybe firefox is using some file cache policy which I don't know. I also checked both two location, my account have read/write access.

I can try to resume the download, and the download progress will increase, but about half a second later it will fail again. If the file is small and my internet speed is fast enough, after several attempts the file will eventually download successfully. # see image #2 I have tried using "private window" or enter "about:profiles" to create/use a new and clean profile, but the issue still persists. # see image #3 I tried using other download tools like "Internet Download Manager", and the download was successful. It's ok for use chrome to download the same file to same disk location. The problem recently emerged, it didn't exist before. At least a month ago, the same computer didn't have this issue. I'm not using parental controls.

As of an hour ago suddenly all of the usual suggestions and autofill with bookmarks in my address bar are wrong and out of order. I didn't close out of or update Firefox, I was just browsing online. I didn't change anything in my settings or have opened that up in days at the minimum. I cannot figure out how to either revert back or tell Firefox to not show me these choices so I can get my old ones.

I'll give an example: When I typed in "ma" it would show me mangadex.com, which I often go to. Now when I do it not only is 5th on the list it shows up and fills in "https://www.manticgames.com/", which I don't have that specific page bookmarked. I have "https://www.manticgames.com/games/kings-of-war/" bookmarked, but not that homepage. But now all of a sudden it is showing me the homepage of that site when I begin to type in "ma".

This is incredibly irritating and I have no idea why it's doing this at me out of nowhere. I don't want about anything showing up besides my bookmarks and specifically only the pages I bookmarked.

The integrated webcam (IMC Networks Integrated Camera, according to lsusb) on my linux laptop does not work in firefox (v124). It works in desktop apps (eg webcamoid), and chromium. I've checked the permissions (about:preferences#privacy), and that is not the problem. about:support does not list the device in the input at all. I've tried using LD_PRELOAD=/usr/lib64/libv4l/libv4l1compat.so, but that has not helped. Does anyone have any suggestions?

When searching with google it always opens a new Tab with some not working Address. Whether i just search or click on pictures or look at a picture more in detail it always opens this tab: Look at picture: At this point it is really annoying and in the settings of the browser i don't seem to find a solution. Please help.

I've tried going into Full Screen mode three different ways:

• Clicking the green MacOS button in the upper left of the window
• In the Firefox menu in the upper right, to the right of the Zoom choice I click the full screen icon
• Pressing Command+Shift+F

But whatever way I do it, I still see the tab bar, address bar, and bookmarks toolbar rather than a true full screen. Not sure what I'm doing wrong.

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

This has been happening to me with recent updates of Firefox, and I am very close to dumping a browser that I have used for years because of it. I go to load pages and it just sits there and spins and spins. In the time I take to open another browser like Chrome and copy and paste the exact same links into Chrome, where the download of the web page is practically instant. I go back to Firefox and it is still spinning and it is just ridiculous. I have no clue what would be causing this. After it finally loads a page, it seems fine on subsequent loads of pages.

https://tasmota.github.io/install/ This is an example of what i am tryingto achieve bit no matter on which site i am , i do not get to choose from ports and my devices and always faults out saying similar messages that the browser does not support web serial in one way or the other for any site doing similar task. error message is as shown in the image shared basically complains of browser not supporting web serial.
