Firefox supportforum

I'm running a UI deployment with a web-app and Firefox on an Ubuntu system.

I'm running Firefox with the flag "--kiosk" to place it into kiosk mode (booted from the command line upon system boot). This works fine, and boots up Firefox to the page I want (my web-app) in kiosk mode (full-screen, etc.)

However, I get very annoying popups that are not acceptable for deployments in front of customers. I have tried, but CANNOT suppress all of them, or, when I thought I did, they came back a month later.

Popups:

1. "Keep pesky trackers off your tail. Open my links with Firefox" 2. "Welcome back" 3. Others like this...

These are Firefox browser popups, not related to popups that other websites can put up, and block the entire screen with an overlay until they are dismissed. My deployments are only going to a single web-page that I control (which has no popups) and there is no keyboard on the deployed system, so people cannot navigate elsewhere.

Things I've tried:

1. Firefox is installed via snap, which provides "snapshotting" configuration for the Firefox snap. I loaded Firefox, cleared the annoying dialogs, and then took a snapshot (theorying that I set Firefox configuration when doing this, and I capture that in the snapshot) and re-installed it onto a new system. Still go popups 2. Looked into user.js preferences. I can install this file onto the system, so I looked through https://searchfox.org/mozilla-release/source/remote/shared/RecommendedPreferences.sys.mjs and this is how I initially got all the popups to disable themselves. I looked through that list and tested most of the recommended settings until the popups disappeared. However, after a month or so, I'm beginning to see the popups again.

Any suggestions from Mozilla or others that run into this issue?

Hi Guys! Huge fan of Firefox since the early 2000s when I first learned about it. Way more secure, efficient, and lighter than any other browser (IE, Chrome, and now Edge). Firefox is my first download on every new device and my go to even on my iPad.

I've been getting this error message lately and I don't know what to make of it. My saved tabs are working normally (email, work, streaming entertainment). This automatically comes out on ever new start / re-start (Firefox is my default) on separate tab but I am not opening any new website. It's been 2-3 days. At first I didn't mind it but its consistently happening and not just a one time thing. I already cleared my cache data. I've also ran a scan and it's come up clean (I have a paid BitDefender subscription). It's also not the local ip of my machine.

So any help would be great as I really don't want to leak any personal data or have any viruses.

Thank you for your time!

Firefox believes I have a security key.

What is a security key? Where do I find it? Why does Firefox think I have one?

And why is there no helpful information to explain this confusing UX?

I use Firefox as my browser and used to be able to go a web site or to a link from an instructor and when I clicked on the link or entered the class I was attending, the Zoom meeting would automatically open. That doesn't work anymore. I have to "join via browser but I don't have the meeting id. Why has this become so difficult? Zoom denies being the problem so now I wonder if it's the browser.

I can't open firefox. message says "firefox quit unexpectedly" and it won't reload. I tried Force Quit. I tried restarting my computer. I tried completely shutting computer down and restarting. It happened very suddenly yesterday.

Hello, have been scratching my head for a while on this one. Have a freshly setup install of Debian 12, using Sway (wayland) as my Window Manager. I am really struggling with slowness in Firefox, page loads take easily 15 seconds whereas loading the exact same page in another window at the same time with Chromium Debian build has near instantaneous load times. I've tried the following troubleshooting steps: - Created a new firefox profile - Tried "Troubleshooting Mode" in Firefox - Disabled ipv6 in firefox about:config and in Debian - Tried different DNS servers - Tried different non-debian specific builds of Firefox - Tried Firefox Beta and Firefox Nightly for Debian

None of these steps made any difference, and Chromium has continued to be significantly faster. Am really stuck here and would love to get to the bottom of this as Firefox is the only browser that works with a HiDPI display in Sway without blurryness. Happy to provide any and all diagnostics and reports that are needed. Thanks in advance!

EDIT: It seems to be some kind of networking issue, using a VPN solves it. But still doesn't explain why Chromium would behave differently.

I have not been able to highlight and copy ~ even prior to the most recent update.

Even using control/ does not work.

Really hating this.

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to (desktop) Firefox section as you have macOS.

Dear Mozilla:

It is SAD that the OS I have will no longer be supported due to exploits.

Considering the # of exploits, backdoors, poor coding, etc., in the later Windows OS versions - 1 would truly think that supporting the older and MUCH more secure Windows OS's would be wise.

Yes, they have "holes", but overall much fewer than current OS's.

Plus, the bad actors are very busy exploiting 10 & 11 and pretty much have ignored the prior versions.

Question... what if a major exploit is found that affects all OS's from 11 down to unsupported?

Will Mozilla make sure to supply a patch to the unsupported due to the danger of the new & serious "hole" found?

I vote... it would be wise to maintain a small contingency of legacy developers to help those who cannot buy new systems or flat out HATE the UI & UX of the 10 & 11.

Makes sense?

Hello

I want to use extension xpi's from a shared external folder over multiple Linux profiles. So i examined the profile folder and found extensions.json. Though i can't find any documentation to it's keys online.

There's "rootURI:" with a "jar:file://path/to/extension.xpi!/", so i tried just replacing the path with the shared one. Though i observed that just makes firefox replace the path with the current one. So i examined further and found the "location:" key with the default value "app-profile". So my guess is, there's other values for other usecases, right?

So, in summary, what i need is:

• documentation to extensions.json keys or possible values to "location" key.
• if that isn't intended/doesn't work, how i can achieve my goal otherwise.

And please don't suggest the sync feature, that doesn't work for my usecase.

BROWSER NO LONGER CHECKS FOR UPDATES (automatic or prompted via HELP>ABOUT) RUNNING 125.0.1 (64-bit) WITH WIN 10 PRO, VPN on or off running NORD 7.22.3.0 Thoughts, or is this now normal? Tks erik

The fundamental nature of dementia and Alzheimers is that the victim cannot remember new information. But for some time they can recall information and processes which were learned previously.

After some years, they will be unable to utilize any of the technology they depend upon - they will not be able to turn on their device to make a phone call. They won't be able to locate the menu they need to utilize. Because all that changes CONSTANTLY. They will become helpless sooner than necessary. They will strain their families and the taxpayer sooner than necessary.

The only solution is for software makers to roll out, every 5 or 6 years, a "stable version" where the user interface will not change one iota for 25 years. Of course, they must still make internal updates for security and changes in the Internet Protocol layer system. The portions of the code that deal with the user must be modular to be plugged into newer hardware and communication protocols.

When someone is diagnosed with memory impairment, they will have time to learn the latest Stable Version.

This is a very fundamental change to business as usual, but there is no other solution other than continuing to balloon the cost of elder car.

In the old days this would be a call for an RFP...

I want to delete firefox logins info and to make sure passwords and logins are never stored. I go to passwords, open up menu, and the "remove all passwords" choice is greyed out. How can I get that choice it be valid and to impliment that operation?? And to never have these stored??

Hello support,

is there any way (other than the one plugin I found that did not work for some reason) to adjust firefox' general brightness (or that of an individual tab) ?

Also changing my monitors brightness would not work for me as I am trying to test a website I develop (using firefox to visualize it) and it is rather just the large difference between my editor (which's brightness you can not adjust) and the browser that is very unpleasent when I switch back and forth (like when trying to fix a bug).

Kindest regards.

After years of accessing www.youtube.com with Firefox with no problem, the website is no longer accessible as of yesterday. When I point my browser to that URL, I get a screen with greyed out video previews, greyed out titles, greyed out account access and a search window that does not do anything. I can access YouTube just fine with Safari. I've cleared my cache. Please advise.

I am trying to access Oracle eBS instance but when I login to the page, I get a notification as shown in the image.

After installing the plug-in and restarting the browser, when I try to run the application, I get the same notification.

Hello,

I like using Firefox browser every day. After installing and running Avast antivirus protection (program version : 24.3.6108 (build 24.3.8975.832)), Avast notification always show this message every time I start up Firefox : please check the uploaded images : FPA Scam.jpg.

I already checked the extenstion, the Settings, and the Advance Settings of Firefox browser. I'd like to know if there is any parameter related to engine.forexpeacearmy.com and it is enabled. Unfortunately, I can't found any related parameters.

So, I decide to contact Firefox support to find out what happen to my Firefox browser, why it always call the forexpeacearmy site at the start up, and finally I want to remove it. Because I'm affraid it could be some kind of trojans / malwares and put my laptop into risks.

Kindly need your advise. Thank you.

Kind regards, Gideon

When I use the `--search` CLI option, Firefox searches the supplied term in a new window.

I want it to open itself in a new tab instead, so I tried out the following combination of CLI options:

``` $ firefox --new-tab --search "example" ```

Firefox does search for the given term, but it opens itself in a new window instead of a new tab, thus ignoring the `--new-tab` option.

Am I doing something wrong?
