Firefox seems to have a problem on Linux using USB Security Keys. I have two Yubico Security Keys which I use for 2FA. The problem seems to be that Firefox cannot communicate with the USB port, as it doesn't make any difference whether the USB Security Key is plugged in or not, the error returned is always the same and the Security Key does not light up.

I believe Firefox's WebAuth code must be fine, as it works on Windows, which is why I think it's some kind of permissions problem. Chrome works perfectly with the Security Keys on my computer.

I've used a number of sites (I've listed a couple below) where you can test your Security Key with Firefox on KDE Neon and the error is always "UnknownError: The operation failed for an unknown transient reason":

https://www.token2.com/tools/fido2-test/ https://demo.yubico.com/webauthn-technical/registration

I cannot log into Bugzilla with GitHub as my GitHub login uses a Security Key as the second factor.

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.

Hello everyone, I wrote an add-on for my own personal use. I don't intend to publish it. So naturally, it isn't verified, but I trust it. I am able to install the add-on as a temporary add-on under about:debugging, and it works as intended. The manifest file contains "browser_specific_settings": {

       "gecko": {
           "id": "example@example.com"
       }

} I would now like to install the add-on permanently. So I packaged it as a zip file. The zip file contains the files directly without a parent folder. Under about:config I set xpinstall.signatures.required, xpinstall.whitelist.required and extensions.langpacks.signatures.required to false. Then I went to about:addons clicked on install add-on from file and selected the zip file. I got the error message: "This addon could not be installed because it has not been verified". I am using Firefox for archlinux, version 112.0.

What am I missing? How can I install this addon?

I apprechiate your answers.

Hi I want to make a commercial offer to Mozilla and I want to be a percentage of it if the team has accepted my offer.

Where should I email the offer? And to whom?

I'm trying to install Firefox on a Chromebook. I've done this successfully before. Using the instructions in the Mozilla page https://support.mozilla.org/en-US/kb/run-firefox-chromeos?utm_source=www.mozilla.org-firefox-browsers-chromebook&utm_medium=referral&utm_campaign=seo#w_installing-the-firefox-desktop-browser-with-flatpak

But the command in the terminal window sudo bash -c "$(curl -fsS https://raw.githubusercontent.com/mozilla/sumo-kb/main/run-firefox-chromeos/install-flatpak.sh)"

Is giving me the error message curl: (22) The requested URL returned error: 404

Any advice would be appreciated! This is a fresh ChromeOS environment since I just did a factory reset so everything should be clean, and with latest OS version.

Thanks

Hi,

Is there any reason firefox would flag an mp4 file legitimately?

• The file extension and file type are absolutely mp4.
• There seem to be no mp4 related zero days.

Does Firefox perhaps just treat all downloads from suspicious domains as malware? Is there a zero day I missed? Is this based on some missing metadata on the file or something?

Thanks for any advice you can give here, I'm scared.

My firefox suddenly became very slow after an update. On each web page I have to wait maybe 10s, and nothing happens, and after that all is ok (really fast). Safe-mode didn't help. Thanks, Piero

FFox 112.0.2 (64-bit) running in Linux Mint 20.3 Una.

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">
// (1/240) sec-per-char +-all-strides-------------------------->
<B class="wheat">24pps</B>                // <B class="purple">(Aa______)(Bb______)(Cc______)(Dd______)</B> source pps
<B class="wheat">_hpps(Aa..Dd)</B>        // <B class="purple">(A_______)(B_______)(C_______)(D_______)</B> source top hpps
                     // <B class="purple">(a_______)(b_______)(c_______)(d_______)</B>        bottom hpps
<B class="wheat">(AaBbBcCdDd)=60hpps</B>  // <B class="purple">(A_-20%)(B_________+60%)(C_-20%)(D_-20%)</B> target top hpps
                     // <B class="purple">(a_-20%)(b_-20%)(c_-20%)(d_________+60%)</B>        bottom hpps
<B class="wheat">]30'1.001htfps</B>       // <B class="purple">[A+a___][B+b___][B+c___][C+d___][D+d___]</B> target htfps
                     //                 ================         combed</PRE>

<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.>

Hi,

I am using Firefox for Linux, and whenever my yubikey is plugged in, firefox will start bothering me for a pkcs#11 password. It always happens on start-up but it gets relentlessly annoying if I happen to be on a site which potentially utilizes certificate auth, which I do not use this yubikey for.

I do however use it for 2fa, which does work perfectly fine.

How do I permanently stop whatever Firefox process keeps bothering me about this PKCS#11 password for functionality that I never use?

I'm currently running Firefox v 112.0.2 on Linux. I've had a theme installed for a while now that I really enjoy. It's a minimalist theme I found on github and then I topped it off with some colors that suite my desktop theme.

The ONLY issue I am having is with the dropdown menus. I can't see any of the list items and I cannot for the life of me figure out where to modify these colors. Searching has only gotten me more confused.

Photo is attached. I'm hoping that changing the text color here is an easy fix. The colors are all fine in other dropdown-ish menus, like bookmark folders for example.

Thanks in advance for any advice.

I can't get Firefox to use some custom cursors. Firefox is only recognizing the cursors that came installed with Ubuntu. Any of the cursors I installed will default to DMZ-White, but Firefox is using those cursors that came installed with Ubuntu. I tried defining the default cursor in /usr/share/icons/default/index.theme but did nothing as well. Also I tried with the cursor in /usr/share/icons and in /home/name/.icons and firefox cannot get in any of those.

I don't know if it's something wrong with my cursors or it's some inner thing with Firefox, any one has a guess? Incompatibility or something missing from the cursor?

Good morning!

Since v112.0.2 my Firefox logged itself out of Sync and will not allow me log back in. When I click the "Sync and Save Data" in the pulldown menu, the page spinner just spins and spins. The login page never loads.

Oddly, I couldn't even login to my Mozilla account here to post this. I had to use "Ungoogled" Chromium to load the page. I've never had any Sync issues with FF, that I can remember. This just "appeared" with v112.0.2 and continues with v113.0.

I did try to access the Sync login page while in Safe (Troubleshooting) Mode... no difference, though; same spinning spinner.

I'm running Slackware Linux on a desktop computer. No other changes have been made on this system other than upgrading from FF v112.0.1. to v112.0.2. This is when the Sync issue started.

Any ideas? Any assitance would be very much appreciated. I could just go to Chromium full-time, but I would not want to do that. I've been a Mozilla browser user for 23 years. The Chromium is only on my system as a backup browser, along with SeaMonkey. Yeah... I have a Seamonkey. :)

Anyway, thanks in advance for any help/ideas to allow me to troubleshoot/resolve this.

Regards,

~Eric

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

Malwarebytes & Privacy Badger appear not to be working, though shown as 'enabled' in 'Extensions'. No blocked content is indicated. Adverts appear on lse.co.uk which can cause all four CPU's on Intel i5 to hit hi 90%. This problem appears to have started in this release.

Have disabled Privacy Badger and installed Adblocker Ultimate. This seems to have cleared the problem and Malwarebytes Browser Guard is now reporting results. Can't see how to mark problem as fixed??

A further observation which may be related to this problem. Response time seems very sluggish on FF 112.0.1

I have re-enabled both Privacy Badger & MalwareBytes and disabled Adblocker Ultimate. Both appear to be functioning now.

I have noticed that the WebExtensions process can consume as much and sometimes double the CPU & memory resource as that needed for the Firefox process. Is this to be expected? Do I need these extra security features, or are they built-in to the browser anyway?

I have a few websites, among them glovoapp.com and work Kibana, that don't open properly in my regular Firefox session any more even though I tried to remove cookies related to those websites and anything else I could think of. They work fine in private window but it means I have to authenticate each time. What steps do I need to perform to completely clean a website settings from Firefox memory?

In case of Glovo (and several other websites) in regular Firefox session there's an error: Content Security Policy: The page's settings blocked the loading of a resource at inline ("script-src"). Same doesn't happen in private window.

In case of Kibana (and several other websites) in regular session Firefox somehow remembers old authentication - it doesn't ask for new credentials and doesn't send Sec-Fetch-User header (which results in Kibana throwing HTTP 405 Method Not Allowed). In private window the header is sent correctly.

I'm using Tridactyl so I tried to use the :sanitise glovoapp.com command which, in theory, should remove everything that can be removed with API calls as described on https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/browsingData/DataTypeSet - it's not enough.

Hi,

I seem to having multiple problems with Firefox over the last few weeks...

This problem is - I can't unblock popups. I have got popup blocking enabled, with a couple of Exceptions - it's been working fine until I wanted to use it today. I have tried turning off popup blocking, re-entering the exceptions - nothing is helping!!!

Does anyone know what to do?

Thanking you Pedro

HI! I've been trying to install Firefox on my new Acer Chromebook by following this article: https://support.mozilla.org/en-US/kb/run-firefox-chromeos. However, whenever i get to the last step, it says "no remote refs found similar to firefox". I have no idea what i'm doing at this point, any help?
