Форум поддержки Firefox

My Subject pretty well says it. I'm trying to transfer by syncing my desktop Firefox with the Firefox 124 on a newly installed Kubuntu on a new laptop. I have all these functions synced ON. The recent history but not the long-term history, passwords (thank heavens), and all bookmarks got transferred, but not the open tabs/pages. I've done the desktop sync followed by the laptop sync a few times, still without the tabs' transferring. How do i get those transferred?

Previously I've been able to select search suggestions using the keyboard when typing into a search bar. As of a few days ago this no longer works on some sites like YouTube, but does work on others like Google. The issue is not to do with num lock or scroll lock, and my browser is up to date (124.0.1 Ubuntu Snap version).

Firefox runs fine most of the time. If I right-click to download an image, or click a link to download a PDF or other file, or Save HTML, I see the "Save file" dialog, click Save and then Firefox freezes up for a while, maybe a minute or two. Pages won't scroll. I can't switch tabs. I can bring up a different firefox window and it redraws its contents, but I can't scroll or do anything else.

This didn't happen a month ago, then one day after a system upgrade, it happens every time. I'm using FF 123.0.1 on Arch Linux. 64GB RAM, so it's not a memory shortage. I have upgraded one or two times more since the upgrade when this appeared. Chromium is not affected, Thunderbird is fine, and all other software continues to be fine as before, including when saving files. Only FF has this problem.

What is the problem and solution? Are there ways to gather more info to diagnose the problem, if needed?

After Ubuntu updated the GPU driver, Firefox stopped rendering and only works when disabling hardware acceleration. See screenshot attached. I'm using ubuntu/ RTX4090 and nvidia-driver-535 (propietary, tested). Attaching the apt upgrade logs that caused this to happen. Firefox is the only application that suffers from this.

Is there any fix happening soon for this?

I want to visit http://bispebjerghospital.dk/ . I have seen on https://www.whatsmydns.net/#A/www.bispebjerghospital.dk that it's DNS isn't propagating correctly, so I turned on "MAX PROTECTION" for DNS, hoping that it would let me see the site.

But Firefox showed me "Unexpected error" the first time I went to the site. And then I clicked 'always allow' and now it just spins and spins with no response visible.

How can I visit the website from one of the countries with red X's on whatsmydns?

I've followed this tutorial on howto install firefox as deb via apt. After successfull installation the menu font looks really wierd. It looks stretched and the numbers are not displayed correctly.

The left image shows snap package install and the right image deb package.

When editing in Gmail, holding a key down does NOT repeat the character or action. e.g. xxxxx when holding down the "x" or deleting multiple characters when holding down the <Backspace> key.

It works properly in other apps (e.g. this dialogue).

And works okay in Gmail in other browsers (e.g. Chromium or Brave).

I'm using Firefox 124 on Linux Mint 20.1.

This one really caught me by surprise! I have an internal Django database system. Staff typically use Firefox or Chrome to access it from Linux or Windows machines. As part of this system, it uses Grappelli library which in turn uses TinyMCE V3.5.8. Specifically, in a text box TinyMCE provides advanced editing and fonting. Allows the user to embed links or images. This system was working fine on Django 2.2. My provider (Python Anywhere) retired the server image I was running on, so I updated everything to Django 4.2 on their latest "haggis" system image. Everything seemed to transfer over without any errors - at first. In fact, it was a week later somebody tried to change a font colour by clicking the popup button that opens a colour picker. That pop up looks blank! (its not, the HTML is there but without the custom CSS nothing is visible)

In developer mode on Firefox or Chrome I can see what the problem is: The popup is disconnected from the parent. The parents CSS and classes - specifically tinyMCE - is not present. So its missing the styling and JS to operate. One of the first things the popup JS does is copy in the tinyMCE and tinymce classes from the parent. But they are not there, in fact .opener is null and .parent is stripped down.

What is really weird is on my test server, where I tested everything before updating the live server, it works! The test server uses Django's "runserver" to run a very simple (unsecure) http server just to test code. Whereas the live server is locked on HTTPS.

What confuses me is I don't see any console log messages that would indicate the browser decided to "protect" me. How can I figure out what is going on? Or disable this feature for a test?

I am writing this on my Dev machine using the browser I test with, so I shall try to paste in tech info below.

Just to reiterate, in this browser I can have my test server in one tab, my live server in another tab, test server popup works; live server popup does not.

Thanks in Advance, Richard

I'm having really odd behavior using Firefox (linux) with Microsoft 365 web apps (outlook, word, excel, etc). Its happening various distros too. Is there a known issue at this time with FF and 365 web apps?

   Excel - cell content deletion on moving through cells.
   Word - line content deletion on hitting carriage return.
   Mail/Cal - Webapp not displaying content on double clicking emails or calendar events.

Found a few sporadic similar reports from users on various forums, but no official note that it was a known bug. Assuming it isn't widespread - anyone here have any anecdotal reports of similar issues. Seems to only affect the linux distro versions of FF.

This renders the web app sites unusable with Firefox so I have had to use another browser for these apps. As these apps are ubiquitous with work and productivity, it's rendering Firefox as a second-choice browser unfortunately. No one really enjoys having to "pick the right browser" for work or play.

Is there any way to resolve these issues? Hoping someone has some insight.

I want my websites content to be remove in reader mode in firefox how i can acheive this.

I am a developer and i am using one div in which i have content and images in that i dont want to fetch them in reader mode.

bold textI am getting "Welcome to ad-free, secure video streaming!" every time I turn on firefox. I can't seem to get rid of it and don't know where it came from. It wants me to "Finish installation" and never installed whatever this is in the first place.

It also tells me "Auto-reporting via Google Analytics is disabled! "

I have no idea what is going on, don't want whatever they are offering, just want it to go away!

I neglected to say that I just 'x' this thing when I see it but it appears whenever I start firefox.

Thoughts?

It doesn't matter if I add www.youtube.com site to hosts file in Linux and delete cache, Firefox just doesn't block it, bypassing my meassures to prevent me to get hooked up here. It was blocking everything as expected some weeks ago. I also tried redirecting to different IP's and it didn't work.

After some checks, I noticed:

• It happens only with www.youtube.com, it doesn't happen with youtube.com (without www)
• Other common pages like other Google pages, Facebook, TikTok or Instagram, get succesfuly blocked by hosts file as expected
• I have tested creating new profiles with about:profiles, but the issue continues
• The issue started after Firefox Developer Edition version 125.0b1 as you may notice in the images attached.
• I also tested with the latest nigthly version and the issue continues.
• DNS over HTTP (DOH) doesn't seems to be the problem since it seems that my network doesn't met the requirements to enable it, and if I manually make sure it's disabled, the issue still continues.
• Chromium browser blocks www.youtube.com as expected, so that indicates my PC might be correctly configured

When I start Firefox on Ubuntu under Wayland, Firefox behaves as if both shift keys just stopped working. In any text field pressing either Shift and any character inputs nothing, e.g. Shift+A inputs nothing instead of "A".

This only happens in Firefox, not in any other app that I checked (terminal, Chrome). It also doesn't happen if I start Firefox in a Xorg session.

Pasting such characters *does* work, e.g. I can paste "about:support" in the URL bar but not type it (":" requires shift).

This also happens when I start Firefox in troubleshooting mode.

What are the next steps in troubleshooting this?

Auto play blocking is no longer working.

media.autoplay.block-event.enabled true media.autoplay.blocking_policy 3 [tried 2] media.autoplay.default 5 [tried values]

Anyone have good values that block auto playing videos?

In case anyone's interested, under Debian 12, when I resume from hibernation, if I have Firefox running as well as Tbird, if I click on a link in an email, the existing instance of Firefox is ignored and a new instance is opened. The first instance is in fact frozen -- it looks as it should but trying to change tabs or open a new tab is inactive. Seems I have to kill the open instance of FF, then if I click on a link in an email, FF pops up as it should with a new tab for the link, but the existing tabs are all there and all functional. It feels like a bug -- Tbird seems not to know that FF is already running.

I'm running Firefox 123.0.1 on Linux Mint 21.2. Something changed after my last update. I visit a number of web sites at which I scroll down a window to a link, click on it to open it, read that link, and then return to the previous page. Examples are news sites like slashdot.org, associated press, or arcamax. Firefox used to return to the place in the original site page where I had clicked on a link. Now, it returns to the top of the original site page, and I have to scroll down again to where I had clicked on a link. I can right click on a link, open a new tab, and then close that tab, but that requires multiple clicks, and I used to just click/click. Is there a way to set up Firefox to go back to the previous behavior? Thanks in advance. ;
