Firefox Community Forum

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 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

I like Ctrl+Shift+B to open the Library (Manage Bookmarks/Show All Bookmarks). For maybe two years I was using this, but it stopped working in 117:

Dorando keyconfig isn't current. Shortkeys won't even install and probably won't do what I want anyway. AutoHotkey will do it, but I'd rather not use it for this.

Does anyone know how I can get a config.js to open the Library when I hit Ctrl+Shift+B?

Hi, I'm having this problem of videos not playing in some websites for a long time now, not even sure how long anymore. It started on Twitter, where I get the error message "The media could not be played". Some time after I got it on Instagram where I get the message "Sorry, we're having trouble with playing this video. Learn More". More recently I subscribed to the Nebula service and got a message there as well "The media could not be loaded". Differently from other people I don't have this problem on Youtube, over there everything has always been fine. I have tried every workaround on this, I have seen many tutorial videos and articles and tried everything and nothing worked. Running on Windows 10

Some things I have tried: -cleared cookies and cache; -disabled all add-ons, removed them even; -checked if firefox was updated; -checked if graphics card drives were updated; -opened websites on incognito mode, nothing changed there; -started Firefox in troubleshoot mode, nothing changed there; -disabled graphics hardware acceleration in Firefox; -enabled autoplay; -reset firefox; -changed my pc actually, installed firefox, got the error and reset firefox again;

Could anyone help me with this? Is this normal?

In Edit > Settings > Search > Search Bar I see a radio button labeled: "Use the address bar for search and navigation"

How do I turn that function completely off?

I occasionally use a site (www.zoomcare.com) which does not work properly with Firefox (I've been using Microsoft Edge (Windows 10) to access it). The problem comes when I try to login. I enter my username and password, and that brings up a blank page that does not redirect to anything, so I'm stuck.

Just out of curiousity, I was looking through Advanced Settings, and found security.csp.enableNavigateTo. It has been set to false, but when I set it to true, I am able to successfully login (I still go to the blank page, but after a brief pause, I'm redirected to a logged-in page).

I'd like to know something about the security implications of enabling this property. Is it a bad idea? (Not knowing, I've set it back to false and will continue to use Edge for now).

The problem is that even after I've tinkered with the about:config settings to prevent Firefox from restoring my previous session after a crash, it just won't listen! The changes I make in about:config don't seem to save, and every time Firefox crashes, it happily reloads my old tabs and windows.

Your assistance would be greatly appreciated!

When i go to google.com and enter search query the tab "hangs" for about 10 seconds before the next page starts to load Same issue on 2 separate machines (1 intel laptop, 1 amd pc) both on newly installed windows 11 pro

what i've tried: safe mode, disabling hardware acceleration, disabling antivirus (kaspersky, without any browser plugins or safe browsing) , but the issue persists

here's the video: https://youtu.be/qMY-38z_TC0

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 have Firefox installed on two PCs. I see the option to add "Recommended by Pocket" under Settings/Home, but on the other one I don't. Screen shots of both are attached. I have completely uninstalled, cleaned up all Firefox files and re-installed Firefox multiple times on the PC where I don't see the Pocket option but nothing changes. Also gone into about:config and tried making changes from there. I want the Pocket recommendations to show on the Firefox Home page for both PCs.

Thanks

I'm getting daily warning notifications from Mcafee about some virus. Don't even have Mcafee. When I go to Settings -> Privacy & Security -> Notifications, there is no Settings button to modify push notifications.

I have followed the steps in the "Prevent Firefox from starting automatically" article: https://support.mozilla.org/en-US/kb/firefox-starts-automatically-when-i-restart-window

But Firefox keeps starting automatically when I restart my computer. Attached is an image of how the settings are now.

What should I do? This is a bit annoying. I don't use Firefox as my main browser but I work as a customer success manager for an online platform and always need to do some tests on Firefox, but I don't want it to start automatically when I turn on my computer.

I'll for instructions.

Thank you

Possibly there was an auto update of MOZILLA FIREFOX on our DELL LAPTOP (Windows 11). Now, we cannot get a Mozilla window to open - due to error message:

XUL Runner Error: Platform version '118.0.1' is not compatible with minVersion >= 118.0 maxVersion <=118.0

Can someone please help us get back to a previous version of Mozilla Fire. Perhaps it is a Windows error. I have no way of knowing. Please help me. My email is: [removed email from public] Thank you.

I've been using Firefox Developer Edition for the past two years without problems. From some point on(about 1 week ago), All browser's search functions suddenly don't work. Navigation bar? Not work. Searchig from Bookmark? Not work. Do not use google? Not work even with duckduckgo. with out DNS? Not work even with 142.250.206.206. There is only one website that i can access with Firefox Developer Edition. It is Mozilla's official website At this moments, I curious that "why isnt work>?" So i used Developer tools, And then I found something amazing. There was no request or response on the Network tab! (Of course, I pressed Ctrl + R) And then, on second thought, I found that the JS function that should have been small in the lower left of the browser screen was not displayed. Finally, I thought, hmm... My Firefox is broken! So i found the FireFox, and then i uninstall it, and reinstall it! All the External Plugin works, OK then What if FireFox????? Unfortunately, Firefox Developer Edition's problem remained the same. I'm sorry that i couldn't even give you a possible cause of the problem. But i SUFFER for a week! Please resolve the issue.....

I used the support article [Hide Tab bar if there is only one tab] to hide the tab bar when there is only one tab. I now regret it and want to go back. I tried browser.tabs.tabmanager.enabled = true but that didn't work. And unfortunately I don't understand the "chosen" solution, so I can't reverse it. The regret is because it's hard to drag a single tab and drop it in another browser window.

This problem started yesterday and I cant seem to fix it where youtube is too wide for my screen without any indicator on the top of my screen saying that its zoomed in and I cant watch any videos fullscreen. This glitch isn't a problem on any other websites. I tried opening and closing the browser, I tried restarting my computer tried clearing my cache and cookies and I tried using different accounts but none of them seem to fix the problem!

Photo 1: What it looks like right now Photo 2: What it should look like (had to use private tab) Photo 3: What search looks like Photo 4: What search should look like Photo 5: I cant see any videos fullscreen

When hit enter key to search with google or some other website that tab just freeze for few second, can't click on anything on that website after that it back to normal like how it work without the freeze

I already try everything i could like disable Firefox Accessibility Service, troubleshooting.

Hi! please help me lmao i'm not sure wtf is going on. I recently (as of a week ago) had to wipe my pc and reinstall windows 10 after a botched update. So i installed firefox on a practically new pc. thing is... when i turn it on, i get this baby in my taskbar (see image): right under the pinned firefox and thunderbird logo, i get a really scrungly OLD (and i mean OLD) firefox logo. clicking it opens nothing. hovering over it shows a preview of a blank window with a random string as title. clicking it only opens a second blank window with nothing in it. eventually when windows finishes starting up, it closes itself. i'm scared it might be a virus. help? how do i make it stop??

I'm running firefox 117.0.1 on windows 10 home single language 1903 (sorry if that's wrong, i dont know where to check otherwise)
