With FF 140.0 on both WIn10 and WIn11, new tabs opened automatically then closed after less than a second. Initially I thought this was due to malware, but on inspecting the History, I found the source of this annoying behavior:

// SidebarUtil.tab.js

// This is just a placeholder file to be loaded in a temporary tab to check if a sidebar is open and how wide it is.

Is there a way to STOP this sidebar checking with its tab opening/closing without disabling Java entirely ? Is this annoying behavior really necessary in FF ?

Since Flathub list the org.mozilla.firefox app as official, i hope this is the correct support channel.

Recently i switched from distro specific package managers to flatpak as my application provider. The firefox flatpak won't play most embedded Video/Media on applications like in-browser fediverse clients, forums, blogs or wikis. Youtube works without any issues, Twitch is fine until there is an adbreak. Then it sometimes stops with the supported format/mime error (screenshot appended), only recoverable by cache-dismissive reload.

I used this Article https://support.mozilla.org/en-US/kb/audio-and-video-firefox and the links it contains to debug without any success. None of these samples play. just shows supported format/mime error https://test-videos.co.uk/bigbuckbunny/mp4-h265 At this test website 1. and 3. example won't play. I provided a screenshot before and after trying to click play on all the examples. https://www.tekeye.uk/html/html5-video-test-page

Contrary to the observed behavior about:support#media claims Software Decoding supported for everything except HEVC.

Chromium Flatpak has no such issues. So i copy the video url and play it with chromium. You can see: dire times.

I don't know about you, but I loathe the recent push by the majority of tech companies to integrate the wasteful and environmentally harmful technology that is Generative AI into every corner of the digital landscape. I am especially disappointed in Firefox following the Gen AI hype and inserting it into our experiences as a default without considering the massive amount of users who are not interested in this tech for morons, those who want nothing to do with said tech, or people like myself who f***ing hate it. I am aware that you can shut off AI features by using Firefox's advanced configuration, so I'm wondering if such an option already exists for this coming rollout feature.

I for one believe Firefox should give its users the option to preemptively opt out of rollout features for things involving Gen AI which many, like me, are in vocal opposition against.

How can I unsync desktop from laptop bookmarks?

Selected update Mozilla to Windows 11 yesterday on desktop and am now seeing two sets of bookmarks on both devices. Laptop bookmarks were originally separate from desktop. Laptop is mine and desktop is my wifes. Did not know that it would auto sync both devices.

Is it possible to unsync/separate?

Thanks

Hello and thank you for the help,

I have tried applying for any college on CCCapply's home page (https://home.cccapply.org/en/) and once I input the college and click it or click enter, I either get stuck at a white page or CCCapply has an error page saying I am using a proxy.

I have tested this on macOS Sequoia, Windows 11, Linux Mint, all on the newest updated Firefox. I also tried this on mobile Android and had the same issue.

I have tried on Campus networks, home networks, and cellular networks, all the same issue. Chrome, Edge, and Opera all work perfectly fine.

After trying normally, I have deleted all browser data/cache, turned off Enhanced Tracking Protection and every security setting I could find in the settings and still run into the same issue.

Thank you for the help, Connor

When I open a browser website through Firefox - it now opens to a small screen. I have to go to settings to make it full screen. It has opened previously in full screen. How do I make it open in full screen now? I'm using a MacBook Air. Thank you.

Hello, I freshly installed my new computer and so my thunderbird version is now newer than before. I use Debian 12 with Thunderbird and Firefox 128.13.0esr now. I do unfortunately not know which version I had before, but I think my problems come from Thunderbird version, not from Debian.

I have 2 problems with the new dialog windows of Print, Save as, Open etc.

1. e.g. when I click on "Print", the dialog window opens and my problem is the position of the Button "Print". Now it is in the upper right corner and always before it was in the lower right corner. Can I change this position of the buttons?

2. e.g. when I click on "Save as", the dialog window opens and my problem is that the field of the filename in the upper middle is much too small in width. Before when this field was at the lower middle to right, there was much more width for the filename. Can I change the width of this field?

All in all my both problems are with dialog windows, which I think are Mozilla / Thunderbird / Firefox exclusive, because in other apps there are dialog windows which look completely different. Is there a way to change the entire "optic" of the dialog windows or maybe I can prevent Mozilla apps from using their own dialogs and use my system standard dialogs?

Best regards

Guten Tag lieber Support,

beim Erstellen eines Lesezeichens (Strg+D aus dem aktuellen Tag heraus) wird dieses nach ~3 Sekunden automatisch angelegt.

Das Verhalten dieser Funktion ist äußerst(!) ärgerlich. Es kann vorkommen, dass sich der Dialog direkt vor dem Anfassen mit der Maus bzw. dem Erkennen / sehen / user action im Bereich des Fensters einfach schließt.

Das Lesezeichen wird dann zwar erstellt, aber in diesem use case muss es nochmal angefasst werden.

Könnt ihr bitte eine Möglichkeit schaffen, dieses automatische Speichern & Schließen-Funktion zu unterbinden? Sollte es schon eine Möglichkeit dafür geben, bin ich offen für Erklärung.

Beste Grüße!

I am experiencing a weird scaling issue on one of my monitors with Firefox. The whole firefox window looks as if it's scaled to high resolution mode. Not just zoom of the content, but the whole window, including the title, toolbars, etc.

Note that only happens on ONE monitor (I've tried this on total 6 monitors now), and it happens only on one Firefox Profile. If I use a new profile, the issue is gone. However, if I copy the profile folder to the newly created profile, the issue comes back.

Here is a screenshot of the two windows opened at the same time on the same screen. Right window is normal, and the left window is the scaled up version.

I don't want to re-create my entire profile if I don't have to. Does anyone know what kind of setting/feature did this and how can I revert it? Since it does not happen on a different profile, and is replicable by copying the profile settings, it must be some kind of a firefox setting somewhere.

After upgrading to version 144 in Windows 11, the portable version of firefox stopped opening, the splash screen appears and shuts down. If you run firefox.exe, it works, but the portable program itself crashes and won't start. There is nothing in the logs, antivirus is off, windows security is turned off. How to fix this?

with my barclaycard account, namely if you visit this URL:

https://bcol.barclaycard.co.uk/as3/UI/#/login/

and then click "Or log in using your 16-digit card number instead?"

then with the box to put the credit card number, months ago I put the wrong number, just one digit wrong,

and now every time I visit that URL the wrong number appears in the autofill box, I have removed all my cookies for barclaycard.co.uk, I have cleared passwords, I have done the lot and the same wrong autofill number keeps appearing! it is highly frustrating!

how do I stop this without completely uninstalling Thunderbird and erasing all stored data for all websites?

I feel there ought to be a button to clear all stored data of all description for any specific domain name, or a button to clear all data on the webpage you are at.

SOMETIMES WE ARE TRYING TO OPEN https://udyamregistration.gov.in/UdyamRegistration.aspx ITS OPENING BUT SOMETIMES NOT OPENING WE ARE UNABLE TO FIND PROBLEM PLEASE SOLVE THIS FROM YOUR END.

I'm having an issue in accessing a website & haven't before. There are 2 e-mail addresses associated w/my account since signing up for Mozilla. Just yesterday it changed after a download & now I'm getting 2-factor set up when accessing one website. Please advise if you have any ideas.

I have been using Firefox for years on my Mac Mini and MacBook Pro, sync has never been a problem.

Now I inherited a Dell laptop, after reinstalling Windows 11 I installed Firefox and logged into my account as normal, and then switched back to using my Mac Mini. The next time I closed and then later reopened Firefox on the Mac Mini, Firefox had logged me out of every website, forgot my entire browsing history, passwords, bookmarks, everything. Its all gone with the exception of 4 of my 16 links on Firefox Home.

So I spent an hour fighting MFA, etc. on the websites I use the most, only to close Firefox and have it log me out and forget everything again. That is now its behavior, it loses everything every time I close the app. It does remember my toolbar settings, and those same 4 links on Firefox Home. i rebooted the computer and the problem remains.

Firefox is still logged into my account, it just doesn't sync or remember anything. Doesn't save cookies, history, nothing. Every time i relaunch the app, Firefox home is back in its default state

I also still have an instance of Firefox open on my MBP, I am now deathly afraid of closing the app for worry it will do the same. I also am afraid of using Firefox on the Windows computer, I absolutely cannot break this more.

How do I fix this this quickly and prevent it from ever happening again? I am getting absolutely buried in computer problems at every turn right now and nothing's getting solved. Every fix for weeks not only fails, but inevitably creates a new problem and I'm sorry but I'm going a little crazy and I really need a break.

Thank you.
