Firefox supportforum

When clicking on a link to an .mp4 file, Firefox navigates to a builtin video player, streaming the remote video file. When Firefox is unable to stream or display a file (as is the case with .mkv or .txt for example), it is downloaded instead.

I simply want .mp4 files to be downloaded when I navigate to them. I tried setting `media.mp4.enabled` to `false`, and that worked, but it also disabled most embedded media players.

When I open "Wheel of Fortune" and click on "Log-in", nothing happens. I am unable to log-in. Using another browser, I have no problem.

Anyone with a suggestion or solution for me?

Just (~20 minutes ago) updated 102.0.1 (64 bit) and now there are white bars across the bottom of each firefox window (see screenshots) except for support.mozilla.org or mozilla.org addresses. Any idea what is going on and/or how to fix it?

This site, Costco Instacart, worked perfectly with Firefox as recently as April 15, 2023 but today fails (see attached image): https://sameday.costco.com/store/costco/storefront?zipcode=11021

Cloudflare believes it is protecting itself from online attacks when accessed by Firefox. The same site worked perfectly today, on the same computer, using Google Chrome.

Cloudflare is a major CDN and many important commercial sites, like Costco Instacart, have their content delivered by Cloudflare so this is a major issue with Firefox. For the moment there is a work-around, use Chrome instead, but it would be better to have Firefox address issues with Cloudflare.

Hi,

I'm using Duckduckgo as my search engine, but when I type in a search string, it Firefox prepends it with https://html.duckduckgo.com/html/... This opens a search page that doesn't follow my dark theme. When I click on a link, another link is added that creates a link back to the same URL, causing a loop. This never happened before I upgraded to Ubuntu 22.04 & the latest version of Firefox, 100.0.2. How can I change this back?

Thanks!

Expected: Firefox displaying all known Unicode characters.

Result: Many characters missing.

Failure page as an example: https://en.wikipedia.org/wiki/Religious_and_political_symbols_in_Unicode

Description: I tried going through a Unicode list Unicode list and the extensive set of characters displayed correctly. However, when reaching further into character sets as shown in the failure page page, many are missing which are not new.

• "Repair encoding. . ." button was not active.
• An encoding switch extension was not able to resolve the issue.
• Troubleshooting mode did not show changes.
• Switched fronts available such as Noto Sans and Roboto Sans without success. Possibly a font failure?

FF keeps replacing

http://mysite.domain.net:3344 with httpS://mysite.domain.net:3344

whatever I try to fix this behavior. Thing is that I own this server and there ever was't any SSL implemented. I mean this - never.

Other browsers (Chromium, Chrome, Opera) don't take such a forcing action, website opens like a charm. Why FF thinks it knows better which URL I really want to open?

I already googled _a lot_ in order to find solution, but no one worked.

Setup: Debian 11 Mate no proxy and no separate "internet security" stuff on laptop (other browsers with default settings confirm that) FF 102.11.0 ESR 64 no addons (all switched off)

already tried: browser.urlbar.autoFill false browser.cache.check_doc_frequency 1 network.stricttransportsecurity.preloadlist false browser.fixup.fallback-to-https false dom.security.https_first false

What else I could do to stop this madness? Thank you in advance for any help

Setting `widget.non-native-theme.enabled` to false no longer works; I still get Firefox's default styling for controls and widgets.

I use a custom GTK3 theme in my environment that I want to apply to Firefox. The above setting works in 91 ESR, and broke with the upgrade to 102 ESR.

A custom user chrome stylesheet would be too painful.

Note: You can revert page styling to defaults in View -> Page Style -> No Style.

When I copy text from other websites, I'm not able to paste in the text field of Whatsapp Web. I'm using Firefox Developer Edition Browser in my laptop. But when I copy text from Whatsapp Web itself, I am able to paste in the text field.

This issue started happening just a few days ago.

Here are my specifications:

Browser: Firefox Developer Edition 117.0b8 (64-bit)

OS: Pop!_OS 21.10

i am using latest firefox (106.0.5, snap) in ubuntu 22.10 64 bit. i have set ubuntu network setting to manual and have set socks proxy there (socks host: 127.0.0.1 port: 2345). while other browsers can connect through system socks proxy, firefox is unable to connect it. i have changed and tested different configs in firefox network menue but no one was helpful. i have also try to solve the problem using foxyproxy addins but it does not correct as expected. sometimes it connects and many time it does not. what is the firefox problem with socks proxy? how can i solve that? thx.

i can't play some (but not all) youtube videos. they do play on other web browsers.

i'm using firefox 106.0.3 on linux suse tumbleweed. Before I upgraded to both of these the same videos were playing ok.

Hi there! I am a long time Chrome user and decided to try Mozilla Firefox. I loved it and after a bit of tweaking, I run into a problem I can't deal with myself. In Chrome I loved auto fill options every time I needed the option for my home address, email address or credit card. In Firefox I just can't do it. The option is only available for Canada or SUA. Is there any way I can make it work? Of course, I looked for some add-ons and actually found several, but given the fact that auto-fill in my case deals with personal and sensitive data, I need a safer method. Is there any? Thank you!

Hello,

I am running Firefox v101.0.1 (64-bit) on Linux (Pop!_OS, installed as a flatpak). I am using the default system theme in dark mode, though switching to the Firefox dark theme or other themes does not change anything. When I allow the Menu Bar (File, Edit, View, etc.) to be present, the browser tabs on the next line are aligned correctly, going all of the way to the left. When I uncheck the Menu Bar, however, a gap appears to the left of the tabs. I have not seen this behavior on Firefox in other environments (Debian, RHEL, Windows), and I'm wondering if there's a way I can remove that gap. I have attached screenshots showing how the tabs are aligned with and without the Menu Bar.

Thanks so much!

Greetings:

First experienced: Friday, Sept 2, when using burpsuite/foxyproxy during a hackerone CTF.

When using other Vbox instances on the same computer I have the same issue. This issue is usually easy to duplicate when using dev-tools or by simply doing an image search and moving the mouse across the images.

Host: Ubuntu 22.04.1 LTS 5.15.0-47-generic #51-Ubuntu SMP Two different VGA controllers are present: Intel CometLake-S GT2 AMD/ATI Ellesmere Radeon RX

VirtualBox: 6.1.34_Ubuntu r150636 (Qt5.15.3) VirtualBox VGA: VMware SVGA II Adapter

Guest: Kali 2022.3 rolling 5.18.0-kali5-amd64 #1 SMP PREEMPT_DYNAMIC Debian 5.18.5-1kali6

Crashes have seem to involve input from the mouse and scroll function within the browser. Once, let us call it a glitch, the crash can either take place while continually moving the mouse around the browser's page or immediately outside the page with the mouse. The "glitch" is a coloration, usually pink or lime-green with characters printed to screen and then disappears. I have been unable to predict when the glitch will happen, thus no screenshot to help.

Steps I have taken:

Googled on the problem which led me to learn about the Firefox about:crashes function.

Viewed about:crashes -- seems to be a Renderer issue linked to llvmpipe or Mesa?

Checked basic system logs for host and guest for anything evident: syslog, kern, Xorg, messages, dmesg, daemon, journalctl.

Used Firefox troubleshooting and extended troubleshooting.

Installed Firefox 104 with same issue.

Reinstalled VirtualBox.

Search on Firefox Renderer issue [from crash report]

     I turned off performance settings, still have same crash issue.

Last Report ID that did not fail to upload: bp-740acc47-0ed4-44a8-851c-ff21b0220905

Ultimately, I am unsure if this is a Firefox, VirtualBox, or Kali Linux issue, but Firefox is the one that this issue is having a severe impact on. My head is spinning at this moment due to all the logs and information I have digested over the weekend.

I appreciate any efforts in helping me decipher what is going on!

Respectfully,

Steve

I upgraded Firefox to 109.0 on OpenSUSE Linux today as an update. Firefox no longer plays videos. Chrome is still playing the videos, so the codecs are on my machine. Is there anything I can do to fix this?

I am going through the https://support.mozilla.org/en-US/kb/containers#w_manage-your-containers page and I dont have the option to add new containers when I click on the icon. I am only shown the choice to open the current page into one of the default containers. If I open a new empty tab, this icon doesnt show up in the url bar.

I have gone through the manage extensions options as well and I cant find a similar option. Can anybody point out what I am missing?

When you open a link from the sidebar while holding ctrl, firefox opens it in a new tab and switches to it immediately; whereas when you click a link from a webpage with ctrl, it does not switch to the new tab (unless you hold shift as well, or check "When you open a link, image or media in a new tab, switch to it immediately" in settings > general > tabs). I would like if firefox does not automatically switch to opened links from the sidebar (history, bookmark, etc.), when I open them with ctrl? (I know I can hold shift to do that, but I was wondering if there might be a preference in about:config to change the reverse this behaviour for sidebars)

Thanks, Ibr.

Hi!

Let's start by saying that I love Firefox, that I use it as my primary browser everywhere and I love that is not based on chromium. However, for reasons to me unknown is missing a very important feature (natively at least): tab grouping. This feature is extremely simple to implement and in today life, where in most jobs (I'm a researcher) you have to deal with a tons of tabs opened in your browser, being able to effectively organize them is a must.

My question is: has Firefox the intention to implement (again) this feature? Will this happen soon?

I'm really trying my best to not switch to a competitor browser and I really want to support Firefox and hope that it gains more and more users. But for this to happen it really needs to be on par with time. How come every other popular browser has a very good tab grouping feature and Firefox doesn't?

Please, let me know if there's a chance to see this feature implemented in reasonable times. Sooner or later, you will probably have to do that reagardless.

Wish you the best, A.

Google offers to use a Google login for many websites in the top-right corner of Firefox, for example, when I start Twitter. I don't remember this behavior more than a few months ago. This is on desktop Firefox, not mobile. I never login to Google unless I want to use Gmail or Blogspot, and then I logoff and kill the browser when done. Can this offer be disabled?
