hi in current version of ff on a win 10 pc.

i have somewhere a fold in ff called "cars"., can anyone tell me how to locATE IT

the advice i previously got no longer works THAanks

Hi everyone,

I looked on multiple forums but can't find an answer.

I am trying to setup 2 way authentication for the Mozilla extensions account. But i can't get past the "Confirm backup authentication code" part.

I get the error:

"There was a problem confirming your backup authentication code"

Here is the codes that i got (can be public because it's expired and i left 2 of them out):

w1bycwwp6w eym2bx8yaj wh5h7c77qv s3snv0ez0x 9aveb72jw1 x8d3rzedah

So i copy just one of them, and i get the error.

• No im not copying all of them, just one
• No i don't have spaces in there
• No there is no capitals or anything in there or caps (im copy pasting).

It's very odd and i can't upload my application.

Please advice. Anyone have some idea?

Thank you in advance!

On any video player that has a gradient, it breaks when I full-screen the video, showing as solid semi-opaque bars instead of the intended gradients.

This happens on any video player I've used that has a gradient, and is most noticeable on YouTube due to the double gradient.

It displays normally when I use snipping tool, so apologies for the bad quality on the second image.

I use Ublock Origin and Dark Reader, but this behaviour doesn't change when either is disabled.

Hello, Since the update on 24 June 2025, bookmarks are displayed in black text on a black background. Is this normal? If not, how can I resolve the issue? I had set it to dark mode, but even when I switched back to light mode, nothing changed. I would appreciate help from the community or Mozilla if anyone has a website address to contact them. Have a nice day.

I had an extension that gave me access to Claude.ai. It was working quite well until this morning, when its CPU shot through the roof. I shut down its tab. I could not figure out how to restart it, and it's not in my extensions list. Was that deprecated? Is there still a direct interface to Claude.ai on Firefox?

I pulled up About:Firefox, and it informs I must restart to update it. That was news to me.

I could also (before restart), do successive Control-T presses to resurrect my Claude.ai. I will try that before restart. Could you tell me what I should look for in the Claude.ai tab, or elsewhere, if Control-T is successful? Thanks,

I cannot for the life of me figure this out. Whenever I load a website that needs location (for example, Google Maps or my province's lottery) and enable location permissions, the websites come back saying they cannot find my location.

I have refreshed Firefox, disabled all Enhanced Tracking Protection, disabled all extensions, and have even ran Firefox in Troubleshoot mode - all to no avail. Is there any way this can be fixed? These websites all work on Chrome and Edge and work on my Firefox for iPhone.

Ever since upgrading to FF 140 yesterday, there is a new icon labeled "Manage use of DRM Software" in the browser just left of the URL, which violently shakes every time I open a website that requires approval to play DRM content.

Now, I do not play any DRM content and have deactivated anything related in the settings, yet every time I open e.g. discord.com where users might embed music or videos in chat rooms (that are optional and ignored by me) that silly icon starts shaking again, which is super annoying.

Is there a way to remove it altogether, or AT LEAST disable the shaking?

After my last Windows 10 update this week, suddenly, Microsoft Family safety settings STOP Firefox from starting up! Can't start Firefox. DRASTIC! DEVASTATING So I HAD to import everything from Firefox to Edge browser, just to send this message. But I left Firefox as my default browser. I am the head my Family group in Family Safety settings.

After clicking on Firefox I get the following message from Family Safety: "You can't use Firefox because of your family safety settings, but it doesn't hurt to ask" Then there's a place to click on: ASK TO USE(Firefox)

  Before clicking on this I removed internet access to my machine. ASK TO USE is a permission FROM Microsoft that never comes if clicked on. These people have HIJACKED my ability to use Firefox.

They should be sued.

браузер не открывает один сайт. остальные сайты открываются. удалял кеш и куки. отключал антивирус. добавлял сайт в файл hosts.

And in private mode, firefox opens this site. help, what can I do?

Hello.

I use Firefox on an computer with Ubuntu, (installed as snap) and have noticed that since the update to version 140 (specifically, version 140.0 canonical-002-1.0), closing a tab causes a noticeable delay : that is, upon any action that would close a tab (clicking on the cross, pressing CTRL+w, or middle clicking), there is a delay of about 200 to 300 ms before the tab is actually closed.

However, during this delay, the window still responds to inputs, leading to rather annoying situations. For example, during regular usage, I usually open a great number of tabs. When I am done with browsing, I close them, by repeatedly clicking the cross button on the tabs. It used to be that the tab under the cursor would immediately close, then the next tab would slide under the cursor, and I would click again to close that one, etc.

But now, when clicking the cross button, the tab is not closed, and when I click again after a small delay (because of muscle memory), the tab is still there. This cause the two single clicks to be treated as a single double-click, which for some reason puts the window in full-screen mode (but only with the snap version; I'm not sure what's going on here).

When using CTRL+w when closing tabs, the delay is still there, but the inputs are correctly handled. If I press CTRL+w three times at the usual rate, I can see the three key presses, then nothing happens for a few instants, then the three tabs close at the same time (i.e. the delay is from input to tab close, not from tab close to other tab close).

This behaviour is completely absent on Firefox (also version 140) on my windows computer.

This delay does not appear when creating tabs, and it does not occur either when closing the window or when closing the last tab in the window (leading to an amusing situation where shutting down Firefox is actually faster then closing a tab). These operation keep going at their previous speed, immeasurably fast to the human eye.

Navigation does not appear to be meaningfully slower than before the update, and the CPU/memory usage is very reasonable.

Curiously, this appears to be a fixed delay. Closing an empty tab takes the same time as closing a very busy one. Closing a tab when there are five takes the same time as closing a tab when there are thirty.

This issue makes browsing feel incredibly sluggish.

Is there a solution for this problem ?

Edit 1 : I have tried to run Firefox in troubleshoot mode, but there was no difference in behaviour. Edit 2 : Fixed typo. Edit 3 : Added exact version. I also tried to refresh Firefox, but the issue remained. Edit 4 : The problem is still present in version 140.0.1 canonical-002-1.0.

Why can't I login into my paypal account in Firefox?????,but if I use Google Chrome,it is not a problem Also On Prime Video,each time I log in(through Firefox) I keep receiving a message about the Browser Is not able to receive HD Videos
