Firefox Support Forum

It has been observed that when a user uses the Firefox browser and tries to download a DDD file, the file format is .pdf instead of .ddd. In the devtools, it was observed that the content-type is text/plain in the response to the request. I changed the content-type to application/octet-stream, but the error still persists

Hello,

I am trying to force two or three websites to detect my timezone as UTC, even though my local system time is not UTC. I figured out how to do this with ALL sites by setting privacy.fingerprintingProtection to "true" and entering "+JSDateTimeUTC" in privacy.fingerprintingProtection.overrides in about:config.

Now according to docs, privacy.fingerprintingProtection.granularOverrides "can be used to add or remove features on a domain granular level if privacy.fingerprintingProtection is enabled," but I can't figure out how to get it working.

Any input is appreciated.

A couple of months ago, I suddenly lost all my saved bookmarks, plus the ones on my toolbar. Strange thing is, all the folders and sub-folders I created are still there, they're just all empty.

Can I get them back somehow? I've been collecting them for years so can't replace them all!

Firefox 125.2 iMac OS x10.15

Hi,

I have Windows OS and use Firefox as my main browser. Firefox settings are set for dark mode and it works in google.com etc, but when I open iCloud Notes, it's full white and not in dark mode. Can someone advise how to change iCloud Notes also to dark mode? I have cleared cache etc, not helping.

After updating Firefox to Firefox 125.0.3, Google ReCaptcha2 stopped working on my sites (I use the invisible version). Then I checked the version from the official website and it doesn’t work either.

I read about self = this on stackoverflow, but this also does not help on my sites. After clicking, nothing happens, and there is an error in the console.

Has anyone encountered this?

The same behavior here https://www.google.com/recaptcha/api2/demo, an error is displayed and loading... loading... loading.

Error in console is like: UncaughtObject { stack: "z<@https://www.gstatic.com/recaptcha/releases/WQcDpAcHn0sjM6ZiVkU8JwNH/recaptcha__ru.js:470:201\nH<@https://www.gstatic.com/recaptcha/releases/WQcDpAcHn0sjM6ZiVkU8JwNH/recaptcha__ru.js:258:...

from https://www.gstatic.com/recaptcha/releases/WQcDpAcHn0sjM6ZiVkU8JwNH/recaptcha__ru.js line 448:1

Tested on absolutely clean Firefox without plugins, with security turned off, without cookies and account.

When i start browsing from Holland IP via VPN the problem are solving. In Chrome, Edge ReCaptcha2 working fine.

Netflix all of a sudden wont work on firefox after update. still works on edge and my computer in other room which has an update firefox popup that i have not done yet. i reset drm already. it wont even sign in through firefox. i was on the phone with netflix for an hour they said use chrome which i hate or edge which is equally horrible but both work just not firefox. f7111-1957-205002 this code popped once. never had this kind of problem before. i already cleared cash and redownloaded firefox and all that jazz.

Anyone else had the problem of not being able to sign in to the Amazon Parent Dashboard via Firefox? But works on Chrome. Same on desktop and android versions of Firefox.

Amazon chat support not helpful and just told me to use Chrome!

PLEASE READ THOROUGHLY - Thru Firefox, I use Tineye to find related photos - I use it all the time, it's been great - I always use a VPN and have never had problems until now (as of yesterday). Now it won't search, a verify you're human window comes up, and I have to keep clicking squares, which I do - but then it says to allow cookies and start over. Well I don't want to allow cookies (Firefox-Mozilla kinda encourages using their tools to block cookies, which I much prefer), and I CANT FIND WHERE TO ALLOW (not yelling its just that I said this before and it wasn't noticed) cookies even if I did (I went to Firefox preferences all I could find was under privacy & security cross-site cookies but that did nothing) and I don't want to disable my VPN. Maybe I should mention that I just added or started a Mozilla account, as I have had immense trouble with my aol emails, and am trying to move everything over to a gmail account. My sign in to Firefox was the aol email, and I had to try (I thought I did it) add another account, which I think I did successfully. So it was right after that, that all this started. Help please! Thank you! I did get the following reply, saying to allow cookies (BUT I DON"T KNOW HOW OR WHERE TO DO IT) and something about a new browser profile and to stay out of my sync account, and I APOLOGIZE, but I have no clue what all that means. What is a broweser profile, what is a sync account and how do I stay out of it? I guess well I know i'm not too smart about this kinda stuff, so I apologize but I think I need detailed step by step what to do to fix this. I know thats a lot of typing, sorry.

When I download PDFs on my MacBook using Firefox (currently 124.0.2 (64-bit)), they are always blank - I have attached a screen shot.

But if I download the same PDF using Safari, it opens straightaway - 2nd screen shot.

Is there something I need to adjust in Firefox to allow PDFs to open?

• Bulleted list itemI understand! You're asking how to use Mozilla Firefox or Safari. Here are some basic steps to get you started:

Mozilla Firefox:

1. Download and install Firefox from the official website. 2. Open Firefox and set your default search engine and homepage. 3. Use the address bar to enter URLs or search queries. 4. Explore the toolbar for bookmarks, history, and extensions. 5. Customize Firefox with themes, add-ons, and settings.

Safari:

1. Open Safari on your Apple device (it comes pre-installed). 2. Use the address bar to enter URLs or search queries. 3. Explore the toolbar for bookmarks, history, and sharing options. 4. Customize Safari with extensions, settings, and privacy features. 5. Use iCloud to sync bookmarks and history across devices.

If you have specific questions or need further assistance, feel free to ask!

I just got a new computer and had my info transferred. It is probably the latest version of Firefox on the new computer now. On the previous version it seems like Favorites was spelled out toward the top of the page on the left hand side. I see now it is just a star icon. Is there any way to get it the way it used to be? I'm sure I will get used to it the new way, but I still liked it the other way. Thanks

Nothing happens when I press the play, like, dislike, notifications, favorite, or join server buttons. On top of this, when I try to open the catalogue it's just a grey screen with nothing in it. In the attached GIF I am clicking rapidly. I don't believe this is an issue with roblox itself, as when I open chrome everything works perfectly. The only extensions I am using for the site are RoPro and BTRoblox. I have tried to turn the extensions off and have even uninstalled them, however the problem was still not fixed.

For the last several days I cannot access my gmail on my PC with firefox. I keep getting an error message that says:

"We’re sorry, but your account is temporarily unavailable. We apologize for the inconvenience and suggest trying again in a few minutes. You can view the Google Workspace Status Dashboard for the current status of the service.

If the issue persists, please visit the Help Center »

Try Again Sign Out"

I keep trying, but to no avail. Gmail works with Chrome on my PC. How can I fix this?

I purchased a new computer, was finally able to download Firefox. When I go to use it, frigging Microsoft BING come up. How do I fix it? Thank you for your help. Susan

p.s. I am at work, the new computer is at home., The version of Firefox was downloaded yesterday and the operating system is Windows 11

I have:

125.0 (64-bit) Mozilla Firefox for Ubuntu canonical - 1.0

Video on Facebook plays without sound. The video plays, I see the image normally, but no sound. Video on Youtube works perfectly.

Fresh install without addons or plugins. Switching to "Troubleshoot mode" does not change anything. Youtube with sound, Facebook without sound.

Any ideas where to look?

v155.9.1esr Debian 12

I'm testing different Debian 12 on multiple VMs, it came to my surprise to see that my VPN hash I used on a website the day before was saved by Firefox on the new VM.

The Sync was on but then which one saved my form (hash)?

1. Numbered list item Logins & Passwords ? note: The hash was not a login but a form. If Firefox saves all the form, you should explicitly rename Logins by any forms/inputs.
2. Numbered list item History? note: I hope this is only URLs.

If Firefox is savings "forms" (input fields) not just "logins" then it should be explicitly written. Is it an expected behavior?

Hi. i have no results while doing this: https://dpaste.com/FTXPQ46ZL# No error, no screenshot. "Screenshot" flags in default state, about:policies - inactive.

Sync just does NOT work. I installed FF on my Mac brand new and fresh... brand new machine. Signed into Sync. NOTHING. After 6-7 HOURS... nothing. It just gets NOTHING AT ALL from my Windows Desktop.

I've signed out of ALL Firefox/Mozilla sync sessions... signed in clean- all browsers are up to date. And the about:sync-log page shows a LONG streak of errors... NON STOP ERRORS.

Why?! Why can't we just sync extensions to install and bookmarks across machines? How is this that hard for Mozilla?!

Day after day and attempt after attempt of failures for a basic function of the browser.

Here is the text of the latest log and showing constant connection errors- mind you NOTHING is breaking on my internet as I'm often streaming things and watching stuff while surfing, or others in the house are. Our connection, and Firefox getting online, are all working fine. I am at a loss. I don't understand how this is so terribly broken out of the box that you can't just sign in and let it talk to their servers. I know Google has billions behind Chrome, but this shouldn't be so 1990's bad by comparison to Chrome sync.

Just updated a friend's computer from Windows 7 to 10. Installed firefox over previous ESR and now there's no way to remove the search bar from the new tab page. On my W10 system, the search bar isn't there, not sure how or why, but on her's there's no option NOT to show it as there used to be.

I found some VERY old (2014) info on this but doesn't seem to be up to date.

PLEASE give us our options back and stop taking them away, sheesh, getting as bad as Microsoft.

Is there a workaround for this to remove the redundant search bar from the new tab page since you can search from the address bar?

Thanks!
