My menu bar is missing. The instructions I have is to click on the open application menu, go to Customize, at the bottom click on 'Toolbars' and then on the menu bar to make the change. I have searched using obvious words like 'customize', 'toolbar'. and 'menu bar', but all I get is 'Not found'. Am I missing something here?

Hello everyone,

For the past few days, I've been seeing the following banner below the address bar on ardmediathek.de :

This website may not work with a VPN. Try signing in or turning VPN off while you use this website.

At first, I assumed this was some kind of anti-VPN or geo-blocking script from the media library itself. However, according to transvision.flod.org it appears to be related to Firefox's ipp-activator-breakage-sign-in-warning feature.

I don't have a VPN, proxy, or DoH enabled, and the VPN button isn't being displayed to me (yet) either. So why is IP Protection interfering here in the first place?

What I think of the ever-growing number of supposedly intelligent services that keep tinkering away in the background and seem to believe they need to take over users' tasks is probably better left unsaid. ;-)

Thanks in advance for any feedback!

Best regards, Martin

I use eBird extensively. When I try to play the audio (with sonograms), I get a message that says "We are still processing this file. Try again later". These files perform well on my Android phone, so I know it it is not eBird's glitch. I am confused about the setting options on Firefox that I need to set. These files are usually .wav format. I have tried to open a ticket with eBird, but have not had a response. Can you guide me? Thanks.

I am trying to use the free VPN in my browser. I have requested IPs in multiple countries and so far all work except the U.S. When I request a U.S. IP address a check shows I am in Chile. When I travel I need a U.S. IP address. What is the issue there?

When opening a new page in Firefox I am shown a few widgets.

It shows the time of sports events and different timezones. But it shows this in a non-local time format - the 12 hour format (so it says 06:00 PM instead of 18:00).

In about:config I found a setting called "browser.newtabpage.activity-stream.widgets.clocks.hourFormat" but what are the acceptable formats to use here? It's not a boolean value, and by default nothing is there. I tried writing 24, HH:mm, and some other things, but didn't notice a difference.

My FFox browser has been invaded by PINK EVERYWHERE Get rid of it in the browser. The suggestions do not seem to do anything to get rid of this horrible color. TFFox 151.0.2 64

Black and white works fine in Menu Bar and web addresses when you finally get your act together.

Some times ago Firefox internal VPN button appeared and this function was very useful. But yesterday this button disapppeared. My location is Russia. I want to return this button back.

I can't find any way to make the settings so that the label prints correctly across the entire sheet. I tried all the settings, nothing helped. Everything prints fine in Google Chrome.

I have been using this wonderful browser since 2012, and it has been my default browser ever since. Recently, I've been facing an issue where I can't upload images, audio files, videos, or any other attachments on WhatsApp Web through this browser. To verify the problem, I tested WhatsApp on a different browser, and everything worked perfectly there.

I would appreciate your advice on how to resolve this issue. Please guide me on what steps I can take to fix the browser and restore normal functionality.

Has Firefox instituted a security setting that is interfering with commerce-related sites? Suddenly I can't log in to my credit union (gets stuck on "authentication" step), amazon.com (endless "transferring data" message during login attempt), and mutual fund sites (similar to amazon.com experience). These all are related to money/commerce. I've turned off Firefox's popup blocking and even explicitly allowed cookies for the sites. I did a Refresh to get rid of extensions that might be causing problems (even though there wasn't a problem a week ago on these sites). I've tried Firefox on a second computer for the credit union site and got the same behavior. Chrome has no problem with these logins, by the way.

For the last maybe 2 weeks of so I have been able to play videos on any website,it is only Firefox that is having the errors. I use Windows 10, and the only extension I have is password managment

I have tried: 1) troubleshoot mode: no changes 2) clearing cache: no change 3) making a new Mozilla profile: no change 4) lowering/turning off security protections 5) refreshing from uninstall 6) uninstalling and reinstalling 7) Allowed autoplay of media 8) toggled off drm

The primary sites that I use are; HBO - error 1K-003 Twitch- error#4000 Patreon- doesn't error out, but just goes black on player Dropout.tv- player error YoutubeLive- Browser error

I have Firefox 151.0.4 in Canada. Windows 10 Pro. No prompt, no button. Tried repair Firefox by uninstall/reinstall. It completely removed all my extensions but no help with VPN. What can I do to enable this feature?

Hi everyone, my website YouTube Thumbnail Downloader

is not loading properly on Firefox, while it seems to work on other browsers. Sometimes the page loads partially or shows styling issues. Has anyone faced a similar problem, and what could be causing it? Any help or troubleshooting suggestions would be appreciated.

Hi,

I'm seeing a strange issue in Firefox when using an online work-hours calculator for payroll calculations.

On this page: https://mauricettecalcul.fr/

When I enter certain hour and minute values and convert them to decimal hours, Firefox occasionally returns a slightly different rounded result compared to Chrome on the same machine. Because these figures are used for payroll, even small rounding differences can be problematic.

I've already tried clearing the cache and testing with extensions disabled, but the behavior remains.

Has anyone experienced browser-specific rounding or calculation differences in Firefox with JavaScript-based calculators? Is there a way to identify whether this is a Firefox issue or something related to how the site handles numeric calculations?

Thanks for any suggestions.

could you guide on what could i be able to do and how do i see those themes section where to see my all installed themes and how i can enable it so that I'll be able to see the changes on my browser?
