Firefox Support Forum

Today I opened Firefox and the tabs were like this. I didn't touch any options in userChrome.css or about:config in months, so I have no idea why it happened (maybe a shortcut or the last update changed something?). How do I go back to a normal height? Thank you kindly for your responses

There is one domain that I get a "server not found" error for even after doing many things to fix it including everything here, https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can#firefox:win10:fx119, checking blocked URLs in the registry, running malware checks, safe mode, reinstalling FF after removing all FF folders from my system.

Before I did a completely clean reinstall, disabling the Open H264 codec (see attached screenshot) would allow me to access the site. But thinking it was needed, I did the clean reinstall. Now disabling it does not allow access to the site.

So far, I have not found any other websites with this problem. It's a .edu domain which happens to be the one I work for! What else can I do?

WhatsApp Web endless loading and general website whatsapp.com does not open correctly in FireFox 119.0. I tested other browsers: Chrome, Brave, Opera - everyone opens WhatsApp normally. I also tested FireFox on other devices with a clean installation - the problem persists.

FireFox 119.0, Windows 10, Windows 11.

I used to be able to use the backspace key to go back one URL in a given window. Now, even though I have gone to about:config and changed browser.backspace_action = 0 to 'true', this no longer works, at least not with my new Windows 11 computer. I tried closing and re-opening Mozilla with the new preference, and again with closing, restarting the computer, and then re-opening Mozilla. Please help if you can. Thank you so much.

I am having an issue with a work site where the content is not being displayed correctly. This site uses microsoft single sign-on with my corporate account and it seems that this is where it breaks, as I am finding errors that point in that direction: GET https://autologon.microsoftazuread-sso.com/softtek.com/winauth/sso?client-request-id=xxxx POST https://login.microsoftonline.com/common/instrumentation/dssostatus Result: NS_BINDING_ABORTED

When I open the same site using Edge (sorry:) it works correctly. The issue is that I do not have control over that website and I use it to enter some work information and I haven't found a way to work around it. I have disabled DNS over HTTPS, HTTPS only mode, Deceptive content protection, allowed single sign-on for microsoft, deleted cookies, etc and nothing seems to work. I hope this gets looked into as it is really an issue that might affect everyone not only at my workplace but others that may use similar functionality. Thank you.

The "Layout.css.page-size.enabled" configuration parameter = False ,worked effectively in previous versions, but after updating to Firefox 119.0, it no longer works whether I set it to True or False.

Orientation option is missing when I try to print documents from a website. The Firefox Print Preview window, which usually allows orientation choices for printing, is now not available.

Please advise. Thanks!

I found that Firefox can automatically generate a QR code for each URL, which is a powerful and useful feature! I'd like to know if this QR code has an expiration date.

To identify myself I had to scan a qr code on a website using my phone. This used to work in firefox but it doesn't anymore. It still works in edge. I'm using firefox 119.0.1 x64 on windows 11 home 22H2. How can I fix this?

I tried to watch a youtube livestream today and it failed to play. Non-live videos on youtube are playing, even the same videos watched as VODs after the stream ends, but the livestreams are providing "Your browser can't play this video" errors.

Simultaneously, I'm noticing that some videos on Reddit (such as embedded tiktok videos) are stuck with a circling ring and won't play. At least some of the same videos will play on Tiktok (when I can find them).

ALSO, when I try to watch videos on my Nebula subscription, I'm getting a "This video could not be loaded: 4" error code. ANY video on Nebula.

What the heck gives?!

Hallo there, somebody knows how I could on my side the log out timeout of any website where I have a login some longer? I am using a forum (ubuntuforums.org) quite often and after only few minutes I am logged out, I have to login again. This is annoying. I would love to manipulate such logins so that the site thinks, I just logged in and does NOT log me out automatically after x minutes or seconds.

Is there such Add-On or setting? I guess its the expiration date of session cookies, isnt it that, where these log outs are calculated? Thanks for hints, I am on Firefox latest (119.0) on Windows and Ubuntu. frank

I use Kubuntu 23.04 with Firefox from mozillateam/ppa apt repository, got update to FF 119 today (package 119.0+build1-0ubuntu0.23.04.1~mt1) and after the update Firefox stopped using system-wide installed fonts (either from /usr/share/fonts or from ~/.local/share/fonts).

So for example fc-list finds Gentium Plus (/usr/share/fonts), Iosevka and Junicode (~/.local/share/fonts) on my system: % fc-list -f '%{family}: %{file}\n' | rg -i 'gentium plus:' Gentium Plus: /usr/share/fonts/truetype/gentiumplus/GentiumPlus-Italic.ttf Gentium Plus: /usr/share/fonts/truetype/gentiumplus/GentiumPlus-BoldItalic.ttf Gentium Plus: /usr/share/fonts/truetype/gentiumplus/GentiumPlus-Bold.ttf Gentium Plus: /usr/share/fonts/truetype/gentiumplus/GentiumPlus-Regular.ttf % fc-list -f '%{family}: %{file}\n' | rg -i 'iosevka:' Iosevka: /home/silmeth/.local/share/fonts/iosevka/iosevka.ttc Iosevka: /home/silmeth/.local/share/fonts/iosevka/iosevka.ttc Iosevka: /home/silmeth/.local/share/fonts/iosevka/iosevka.ttc Iosevka: /home/silmeth/.local/share/fonts/iosevka/iosevka.ttc % fc-list -f '%{family}: %{file}\n' | rg -i 'junicode:' Junicode: /home/silmeth/.local/share/fonts/junicode/otf/Junicode-Bold.otf Junicode: /home/silmeth/.local/share/fonts/junicode/otf/Junicode-Regular.otf Junicode: /home/silmeth/.local/share/fonts/junicode/otf/Junicode-Italic.otf Junicode: /home/silmeth/.local/share/fonts/junicode/otf/Junicode-BoldItalic.otf

but when I try to apply the style `font-family: Gentium Plus`, `font-family: Iosevka`, or `font-family: Junicode` to an element, Firefox doesn’t use those fonts and instead in the element inspector I see Noto Serif is being used instead.

Before the update the appropriate system fonts were being chosen for rendering by Firefox.

Outlook recently made Edge or Chrome the default browser, with no possibility (as far as I can see) of choosing Firefox. In Outlook FILE/OPTIONS/ADVANCED, it seem impossible to choose Firefox.

How can I make Firefox the default browser. This situation occurred after recent update (October 2023).

Any help would be appreciated. -- JGS

I cannot figure out how to export my bookmarks from Mozilla Account. On the desktop browser when I open "Manage Bookmarks" and select Phil's Bookmarks, I am able to export the bookmarks from the Mozilla account.

The resulting html export file does not contain the bookmarks from Mozilla Account. There also does not seem to be a way to export those bookmarks from your online Mozilla Account interface.

How do I export the bookmarks from my Mozilla Account?

Thank you Philip Rittscher

On both my old laptop and a new one (so a new installation of Firefox), I'm unable to load Frontier Airlines' website (www.flyfrontier.com) and get a time-out message:

The connection has timed out

The server at flyfrontier.com is taking too long to respond.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

This happens even with all of my extensions disabled, with enhanced tracking protection turned off for that site and with HTTPS-only mode and DNS over HTTPS disabled. It also happens when using Firefox in safe mode. Safari loads the same website very quickly and with no problems. Does anyone know what might be going wrong? Thanks.

Lately, far too many websites I try to open, simply won't! Sometimes it's via links from my home page, sometimes it's links within various websites, like a newspaper, or social media, just whatever, no rhyme nor reason, nor consistency. Even when I manually input the url, nothing happens, the browser just sits there, nothing happens. I've restarted, I've refreshed websites, clicked on "open in new tab/window", nothing gets it to work.

My browser was just updated today and now my Toolbar Bookmarks are missing from the toolbar. "Most Visited" with a gear is on the left and Other Bookmarks with hardly anything in it is on the far right. I have to go to Bookmarks at the top to access my Toolbar Bookmarks. This is not very handy. I put the bookmarks I need all the time on the toolbar.

Bookmarks toolbar is set to "Always Show". It was fine before the update so...

I often see that some pages take up too much memory. This critically affects the performance of my laptop with 8 GB of memory. However, I was unable to reproduce this behaviour. Now I have caught two web pages.

https://linuxhandbook.com/sort-top-command/ 

and https://www.tutorialspoint.com/how-to-find-number-of-ram-slots-in-linux The first page quickly takes up 1-2GB and continues to drain memory. The maximum usage was 7 GB on a laptop with 16 GB of memory. This behaviour is the same in Firefox and Chrome. The second page quickly takes up 2GB, which is very noticeable on 8GB laptops. Why do these pages take up so much memory? Most importantly, how can you protect yourself from such an unexpected memory consumption?

Firefox remebers my data for previously filled in forms - thats fine. BUtr how can I get it to know my basic data (name, email, phone number etc) for forms / sites I havent previously visited?
