Firefox Community Forum

I use Firefox on both my work and home computer as well as my Android phone. I have for years, and until I got a Surface 8 Pro with Windows 11 Home (in case that matters), the behavior across devices was generally consistent, especially after I created a profile and signed into it across all of my devices. Firefox on that device, though, has given me a couple weird differences/issues.

First, I've noticed that the pop-up blocker seems much more "sensitive" on my home computer than on any other devices. A link I click on on my home computer will trigger the pop-up blocker, whereas my work computer will just send me to the link. An example where I see a different behavior is on the Wordle home page: https://www.nytimes.com/games/wordle/index.html. When I click the light bulb at the top on my home computer, the pop-up blocker is triggered, but when I do the same from my work computer, it just goes straight to the link that icon is for.

Now more recently, I've found that sound from a webpage (say YouTube) played on my home computer comes out of the speakers regardless of whether there's a device in the audio jack, which of course my work computer does not do. I've confirmed it's a Firefox problem and not a larger device problem, as other programs output to the audio jack when something is plugged in there just fine.

I've tried resetting my device obviously, and I've even tried doing a Firefox refresh, progressively deleting more and more profile information, and finally uninstalling Firefox completely, removing the Mozilla folder in %APPDATA%, and removing the registry entries that Revo Uninstaller identified, to try to make it as close as possible to the "factory" default, all to no avail.

Images appear fine, but lately I cannot see embedded videos on websites when I'm browsing. This is a recent change (past couple of weeks).

I can view the same videos using another browser, so I think this is a firefox setting possibly.

All my tabs (I think they're tabs - on the menu bar just below the main menu at the top left of the home screen - have disappeared. I checked history, hoping to replace them and the returned. But now they've vanished again. Also, when FF opens, email screen displayed is 'primary' and it says there are no primary messages. I've always used 'all mail' so I go to that site (which is in a folder on the menu which is below the address bar) and click on it to get to mail.

How can I restore the missing tabs which were on the menu bar just above the address bar?

Many thanks.

When I sign on i get a strange message - see below.

Secure Connection Failed

I don't know what this means and how I can get rid of it. Is it important? Doug Conley

Beginning last night, none of my bookmarks worked. Also the icons on the toolbar are all different (sort of a globe in white outline with a label of the site). My browser indicates it is current.

I have tried all the suggestions clear cache, restart, refresh, turned off extensions etc. but these have not resolved the issue, also this has only started happening within the last couple of weeks.

Firefox is an excellent product. Thank you.

Pocket was removed some time ago. is there any way to get back the aspect of Pocket that allowed capturing the text and pictures from a website and copying and pasting that to (for example ) a Microsoft Word document?

Maybe a third party, as long as it was approved by Firefox.

Thank you.

”Using my HP Notebook computer, BOOKMARKS (in Mozilla/Firefox): Who governs my access to my list, which disappeared on 2/20/2026. It looks like Google (i.e., Yahoo) has taken control of this function……….and, if I set up Sync on my computer, how will my current DEFAULT YAHOO EMAIL be impacted?”

Almost every time I open up Firefox it has a little pop-up under the tool bar asking "Open Firefox every time you restart your computer?", and every time I select "Not now", which I guess is intended as only a temporary answer. How can I permanently say "No" and keep this from popping up constantly?

Pretty sure I've got a problem with a fake certificate / server: in ISRG Root X1. > R13 >. "interfaithpowerandlight.org". This is a legit and very good org, but it ain't no server. A notification pops up intermittently on both mac and iphone that it can't be verified, at which point I've been clicking on cancel. Suggestions, please and thank you?

Hi Team,

I’m currently conducting a DevOps training session and we are using Firefox to inspect headers for a web app running inside a local Docker container (localhost:8080).

We've noticed that occasionally the 'Network' tab in DevTools fails to show the full response headers for our nginx proxy, even after clearing the cache. It works fine in other browsers, but I prefer using Firefox for our students because of the superior CSS Grid and Flexbox tools.

Is there a specific setting in about:config that might be limiting the capture of headers for local loopback addresses?

Thanks for the help!

Firefox stopped working properly this morning. whenever i try and open a new tab firefox tries to get me to setup sync instead of going to the new website. I turned off sync. I do not want to sync with anything at this time. How can i get firefox to work again?

I've just switched to Fedora 43 KDE plasma from Windows. On Windows, everything was totally find with videos on Firefox. After migration I kept having an error message "The media playback was aborted due to a corruption problem or because the media used features your browser did not support." not only on one site (else it could have been the site). After searching for solution here and on the Net, I found out that it's not related to Fedora but to Firefox when using Radeon RX7700XT on Linux (idem with several distros). And indeed, when installing other browser and testing them there was no problem, even with LibreWolf. So can you please take action as I like Firefox and I would not like to have to move everything to an other browser. And it seems that this problem has been around for at least two years ... which you should be ashamed of.

Ever since the last Mozilla update several of my financial institutions or bill payment sites keep coming up with security certificates warning screen. Is this a known issue and will it be fixed?
