I love Firefox, I use it on all my devices. And daily I access facebook.com on this browser, it's been working flawlessly - until yesterday. Yesterday, using Firefox (ver 130.0.1) on my Windows 10 PC, I tried accessing a FB page which I visit sometimes: https://www.facebook.com/OpenOscillator

Rather than reaching that page, I got a white screen with this error message: "Sorry, something went wrong." And since then, even visiting the Facebook home page (or any other FB page) has the same error message.

Today I tried the same thing on my Mac (OS 14.3), using Firefox and logging into facebook.com, which worked as usual. But when I went to https://www.facebook.com/OpenOscillator, I got the same error message: "Sorry, something went wrong." And as happened on my PC, now on my Mac I can't access any FB page on Firefox.

And just to mention, I've rebooted both the PC and the Mac, yet this problem persists on both devices.

Trying this same exercise on Edge on my PC does not have this problem. Nor does it happen when doing this on Safari on my Mac.

So, this problem has only been happening on Firefox. I can no longer access facebook.com with Firefox. Do you guys have any ideas how to solve this?

Helpful to know: Do you have the same outcome if you visit this FB page: https://www.facebook.com/OpenOscillator

Thanks for your assistance! Steven

Hello all

There was a pop-up on my Mac'S Firefox asking if I allow Firefox access to my local network devices. I clicked on 'No' And obviously now I can't access for example my router's webpage or any other webpage fromo any devices on my local network. How I can switch it back? Internet access is working fine.

Many thanks, Bogdan

At some point Firefox stopped allowing me to drag tabs or bookmarks around. This includes moving tabs around in their order, dragging a tab into a new window, dragging tabs into bookmarks, moving bookmarks around in the browser. I can't drag them around in 'manage bookmarks' either. I can still open and create bookmarks; they are simply much more difficult to place where I want them.

I believe this happened with the last update but it's not a feature I use all that often so it could be older.

I have opened Firefox in safe mode and had the same issue. I have turned off the computer several times since this began.

Any help would be appreciated.

I currently can't stream anything, and this keep getting this message: Widevine Content Decryption Module provided by Google Inc. will be installed shortly,but it never installs.

I have a macbook air and am currently running macOS Sequoia version 15.0.1.

I tried uninstalling and reinstalling, removing extensions, clearing cache and data, unchecking and then checking back again the reproduce drm protected content but nothing has worked.

Yahoo isn't loading at all for me, more specifically guce.yahoo.com. I have managed to get into the login.yahoo.com page and log in but after the log in process it goes to the first page again and gives me the same "The connection has timed out". I just installed the browser and this might make me not use it ngl. I have tried both clearing cookies and troubleshooting mode.

I use Google search and do not like the AI overview feature. In the Chrome, Edge, and Opera browser I've added an extension that blocks the AI. What I've noticed when I use FF I see no AI results when using Google search and I've not added an AI overview block extension. Is there something different about FF that prevents AI results from showing without the need for an extension? I look forward to your comments. Thanks

As the title states, certain media elements within Firefox refuse to play with audio, but only with frustrating inconsistency. For example, any videos on Youtube are fine. Any videos on Reddit are fine. But many videos, most commonly on boorus and streaming sites I cannot name here, will not play. The volume on the video slider is all the way up, the Firefox application is not muted, the site is not muted, and the tab is not muted. The only thing that makes those videos play audio is if I left click on them to open them in another tab by themselves. While it solves the issue, it's still an extremely inconvenient way to go about my browsing. I know for a fact that this is a Firefox problem because those same videos on those same sites work perfectly fine within other browsers. Please, does anybody know of a solution to this issue?

Since 141 update I have constant problems with youtube. Page does not load at all or loads only partially. Icons on sidebar are broken, youtube logo is black. I tried disabling ublock and greasemonkey but it did not help. Refreshing page multiple times and using ctrl+f5 sometimes helps but issue returns often, every few videos/visits. Clearing cookies helps but only for few hours and then issue returns.

Is it related to WebGPU support that was supposed to be added in 141? Can I disable it somehow?

Ok so I usually choose these option to remember history and from time to time delete Browsing & download history and Temporary cached files and pages.

Note: I have "Open previous window and tabs" ticked in general settings which also has a restore previous session option in the history menu. This brings back previous session with tabs etc as is when I close FF. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-51-cf2daf.png

I thought I could automate this on exit but don't think its working right. So I change the option to "use custom settings for history" and tick all three options:

Remember browsing and download history Remember search and form history Clear history when Firefox closes For "Clear history when Firefox closes" I ticked Browsing & download history and Temporary cached files and pages. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-43-b10213.png

The issue is the restore session option is missing and FF opens with all previous tabs gone. I am frankly not even sure what else is missing such as cookies, site data etc. Is this meant to work like so?

Running Firefox 133.0.3 on Windows 10 22H2

The last week or so, when I try to download my photos from iCloud, Firefox blocks the download, saying it contains a virus or malware. Of course it does not - it's a zip file of screenshots! Running a scan on the folder once unzipped confirms there is nothing malicious in it. Can you fix that please?

I'm trying to view my routers page at http://192.168.43.1.

Even though I type the full address with http: at the start Firefox automatically inserts https//.

This doesn't work as the router doesn't have a secure page.

I've gone into Firefox settings and found HTTPS-Only Mode is not enabled.

How do I view an HTTP site?

my extensions got unpinned and the new tab button is gone, the tab overview is gone, the extension button is to the left of the address bar, the back and forward buttons are to the left of the address bar, the back and forward button are swapped, WHY.

In the screenshot i pinned the 3 extesions i use again, they were unpinned before

I got a new PC and tried to import my Firefox bookmarks. But on the right side menu when you click bookmarks, it only show recent ones which actually aren't recent at all. How do you get that selection to show all of the bookmarks instead of recent?

Also I'm still getting a prompt underneath the address box to manage bookmarks and I can't get rid of it. How do I clear that out?

I run the latest version of Firefox.

Lately it refuses to open on first attempt - be it from a start menu link or double-clicking the shortcut on my desktop or trying to open a html file directly.

It's annoying and i'd like to fix it.

I've done all the usual stuff like clearing the cache.

I can't watch youtube videos because the player is hidden idk, i just see blank space in the place where the player should be, but in private window youtube works. What happened and what should i do to fix this?

as title says, what the [expletive] hell is this [expletive], why the [expletive] is it enabled by default and how the [expletive] hell do I get rid of this [expletive] [expletive]

Hello=)

I am using Firefox v128.2 esr 64bit on big sur 11.7.10..

In firefox there is always this white line on top of the screen when fullscreening a yt video... (but also partial bars in other situations-randomly) (temp workaround : cmd+up arrow . But, whenever you pause or press something it reappears.

Can we please implement a more elegant solution?

Thanks a bunch , dear Mozillians=)

Have an excellent day=)

I'm using this shortcut all the time and I recently found out it doesn't work as expected. From the Firefox documentation the ctrl+shift+t should re-open the latest closed tab, but this is not the case for me, it always re-open the latest closed window. Which behave exactly as ctrl+shift+n.

From my short research it's not possible to customize Firefox shortcuts without using an extensions, therefore I also don't know how to verify if the shortcuts have changed just form my browser/configuration.
