Hello,

I see with windows Firefox version 118 a TLS extension id 65037 on every client hello handshake containing a bunch of data. Does somebody know what this extension is used for? I couldn't find anything about this on the web or in the firefox docs / release notes. Other browser (chrome / edge) don't have this extension in use.

Thanks

In windows 10, I got used to opening a new window in FF and then a "tab" for the new window would open in the taskbar. I could then switch between windows by clicking on these tabs on the taskbar. In windows 11, I can click on the FF icon in the taskbar and open a new window, but a tab for that new window no longer appears on the taskbar. Instead of the previous tabs on the taskbar for each new/open window, there is nothing. I have tried the suggestion, found in another thread, to use about:config to change to false the setting browser.taskbar.previews.enable, but there was no difference. Does someone know another approach, or is this a windows 11 "feature"?

On a site with a menu along the top the rightmost item is missing, and only in Firefox, not Chrome or Edge. It happens on various pages with the same menu setup. I cleared cookies & cache, turned off extensions, no luck. See attached image. What could the problem be ?

I ran a loghttps://pastebin.com/jydVHHs0 of playing a youtube video mediaencoder? not sure if encoding issue or something else

The videos take a long time to play. I upgraded my system recently and was removing and reinstalling audio-related utilities with DNF.

For some reason every type of embedded video, youtube, webms, etc, all show up washed out in white. This only happens in FF and I have tried a few ways to fix, but no luck. Any ideas?

Thanks.

Seems like in a recent upgrade an additional empty toolbar row was added to Firefox. How to remove it? When I view "Customize toolbars" I see the following page. How to remove the additional empty toolbar? I've read other answers to this problem here and see no way to execute those instructions. Thanks!

When I click on a link from an email or document, Firefox opens but goes to my homepage and doesn't go to the link page. I've tried setting my home page to blank, changed the settings for opening a new tab or window, and the one for "switch to it immediately" but it doesn't seem to help. How do I fix this? Thanks, A PS I'm on Mac OS 10.15.7 Catalina with Firefox 117.0

When I open a new tab, i would like the page to be in focus and not the urlbar. This is what i used to have in my mozilla.cfg: ``` // Auto focus new tab content try {

 Cu.import("resource://gre/modules/Services.jsm");
 Cu.import("resource:///modules/BrowserWindowTracker.jsm");

 Services.obs.addObserver((event) => {
   window = BrowserWindowTracker.getTopWindow();
   window.gBrowser.selectedBrowser.focus();
 }, "browser-open-newtab-start");

} catch(e) { Cu.reportError(e); } ``` This worked until the last update. What solutions are there?

Chrome scrolls to element while Firefox doesn't for this URL with # :

https://www.service-public.fr/particuliers/actualites/A15610#titreChapitre_-5776306477855185115

There is an element with id "titreChapitre_-5776306477855185115" in the page (chapter "Personnes ayant un test de dépistage positif" which means "People who test positive to Covid", Chrome will scroll to this chapter (well, at least 60% of time it auto scrolls to the element) while Firefox will always display the top of the page.

Firefox is slightly better and more similar to Chrome on the english version for some reason : https://www.service-public.fr/particuliers/actualites/A15610?lang=en#titreChapitre_-5634635573997558496

I am using some custom SVG icons for my bookmark folders. I had my userChrome.css setup to set the icons based on the folder names, as well as color the icons with whatever the theme color was. This userChrome.css file worked fine in Firefox 116, but no longer works in 117. Now a couple of the icons are invisible, and the rest of them are black instead of the expected purple color from my theme. Can anyone help?

I’m having trouble moving firefox to a new computer. I copy the files, expecting to see my existing set up with bookmarks, extensions, and passwords, and I get no response, no errors, just completely fresh firefox.

Both systems are on arch linux and both running Firefox 117.0. I completely close both firefox. I copy ~/.mozilla/firefox to an ext4 thumb drive from my old computer. on the new computer, I delete the existing ~/.mozilla/firefox. I copy the files from the thumb drive to /firefox/. I restart firefox. unmodified firefox

I’ve also tried chowing the files. and also chmoding 700 and 755 (advice from old stackoverflow threads) ive tried chowing and chmoding. Each time i restart the whole process for posterity. Still no response

I’m dumbfounded as to why it’s not working, and I don’t even know where to look now

I often need to be able to use the arrow keys to navigate my screen, especially in order to find and click on browser links. However, in the latest version of Firefox on a new macOS Ventura machine, the arrow keys are interpreted by Firefox even though they shouldn't be; at the least corresponding box in "Settings" is unchecked.

How can toggle this behavior off?

Thank you, David Romano

When i go to open a PDF file with Firefox, the text renders incorrectly (see image) for most PDF files, but not all (i'm not sure why. And this only happens with the Flatpak version of Firefox [1]. It doesn't happen with Firefox ESR (DEB version from my distribution) [2] and it doesn't happen if i view the same PDF file with pdf.js in a non-Firefox Flatpak app (GNOME Web) [3].

I've tried reinstalling and tried starting in troubleshoot mode, but neither seemed to fix the issue.

[1]:

• Name: Firefox
• Version: 117.0
• Distribution ID: mozilla-flatpak

[2]:

• Name: Firefox
• Version: 102.15.0esr
• Distribution ID: BLANK (preinstalled with Debian Linux 12)

[3]:

• Name: GNOME Web (Flatpak)
• Version: 44.6

I tried every solution posted and then I uninstalled and then wiped Firefox. Nothing helped. It seemed the picture would not sync or just freeze with the sound still playing. I came across an old post to change media.mediasource.enabled. Mine was already set on true. When I changed it to false it solved the problem.

I was having trouble switching and logging out of Twitter so I thought I could just clear site cookies to make it work, but I weirdly discovered "about:preferences -> Manage Data -> Remove Selected / Remove All Shown" has no effect. i.e. after clearing, when I open up manage data again, they are still there. I did not try "Clear Data" above it because I was afraid of clearing out all my logins.

I reinstalled my computer several weeks ago and current profile was directly copied from my last machine, so this might be a possible cause? Could someone be so kind to help me get remove cookies and hopefully twitter back to work? Thank you in advance.

Hello!

I recently got a new computer with Windows 11 freshly installed. I downloaded Firefox, went to take a screenshot, and the usual shortcut of Ctrl + Shift + S does not work. I can right click and Take a Screenshot, and I can use other Ctrl + Shift shortcuts, like Ctrl + Shift + T to reopen closed tabs. The only one that doesn't work is screenshots. I can also put Screenshots in my top row Toolbar and use it, just not the keyboard shortcut.

I refreshed Firefox, uninstalled and reinstalled Firefox, as well as checked the about:config extensions.screenshots.disabled preference. It has been set to false, so I have set it to true and false again hoping it would "reset" it but nothing. Thank you!

I am trying to set up a Shopify page. It was working fine until today. The page is now redirecting me to the sign in page every time I attempt an action. Shopify support says that they were able to perform these actions on my account from their end. Also, I was able to complete the tasks from Microsoft Edge. Any suggestions.
