How do I stop Firefox (Win 11, Outlook Classic) from daily asking if I want to set it as my default browser? I have browser on desktop but it doesn't tell me Firefox version I have.

Nach dem letzten update ist alles anders. Gespeicherte Ordner,, Lesezeichen, gesamten Erscheinungsbild ist weg bzw. nicht schön. Ich möchte meine alte Version wieder zurück.

I'm not sure when it started happening, but whenever I'm watching something full screen, or just full screening, Firefox on Mac, there's this thin white line at the top of the window that's very distracting. Has this been happening to anyone else and does anyone else know how to get rid of it?

Firefox says: "Pop-up ads, you’re going down.

"Firefox for iOS now has a built-in ad blocker that helps cut down on annoying ad junk, so there’s more room for what you actually came to see. Turn it on under Settings > Browsing."

However there seems to be no "Settings > Browsing". The only reference to browsing that I find under Settings is the following: (see uploaded image). No mention of blocking ads.

my landline has now been disconected. my broadband provider is still PLUSNET. an e mail containing my contract has been sent but i cannot view it because a message saying ACCESS DENIED keeps appearing. it advises me to go to SETTINGS and enable cookies in my BROWSER. this i have done [but they were already enabled]. still message arrives saying ACCESS DENIED. where do i go from here pse.

Hello,

After Firefox automatically updated to version 156.0 (64-bit) on Windows 11, I can no longer change the browser interface language.

The browser UI is currently displayed in English. In Settings > Languages, I can select Chinese as the Browser Language, but the change is never applied.

What happens: - I select Chinese as the Browser Language. - Firefox asks to restart (or saves the setting). - After restarting Firefox, the entire interface is still in English. - Rebooting Windows does not help. - The setting appears to be ignored.

Before updating to Firefox 156, the browser language worked correctly.

Additional information: - Firefox version: 156.0 (64-bit) - Operating system: Windows 11 - The issue started immediately after the automatic update. - Website language settings work normally. - Only the browser UI language cannot be changed.

Has anyone else experienced this issue after updating to Firefox 156?

Thank you.

i keep getting this message for last 2 weeks

Looks like there’s a problem with this site

The server at vlaq11.site sent back an error: 429 Too Many Requests What can you do about it?

   Check to make sure you’ve typed the web site address correctly.
   The site could be temporarily unavailable or too busy. Try again in a few moments.

The taskbar (the one with the Start menu) doesn't hide when watching videos in fullscreen mode. This happens on YouTube as well as on any other website. The problem disappears if I run the browser in Safe Mode. It's only Firefox that doesn't work — in Chrome the taskbar does disappear.

не скрывается панель задач(панель с меню пуск) при просмотре видео в полноэкранном режиме. не работает как на ютубе так и на любом другом сайте. проблема исчезает если запускать браузер в безопасном режиме. не работает только firefox в chrome панель задач пропадает

Здравствуйте! Есть вопрос: есть ли возможность управлять расширением вне браузера? Хотелось бы, чтобы горячие клавиши работали вне браузера. Я использую расширение для музыки, в котором есть настройка переключения музыки горячими клавишами, но вне браузера они не работают. Можно ли сделать так, чтобы они работали, когда браузер свернут? То есть расширить область их применения до глобального уровня.

When I pull up videos, some of them run fine while the majority will stutter heavily. I'm not sure if they're av1 encoded but I tried the same videos with helium browser and chromium and they do not have this issue. I have "Use hardware acceleration when available" turned on and I use a 7800x3d cpu, rtx 5080, 64gb of ram, and 2tb of storage on an nvme m.2 drive. If anyone can find a fix for this it would be greatly appreciated.

I been using FireFox for at least a decade I am really disappointed in it's current state. It is very slow OIS is Version 26.6.2 (25G83). Constantly telling me it can't find server when I hit an website link? Also frequently says secure connection? I want my FireFox back.

Hello Mozilla Support Community,

We are currently optimizing a web-based UK vehicle lookup tool (regchecker.co.uk) to work seamlessly as a Firefox Search Engine Provider (OpenSearch XML) and Progressive Web App (PWA) for Firefox users on Desktop and Android.

Architecture & Setup:

Primary Domain: (regchecker.co.uk)

Implementation: OpenSearch XML integration for quick vehicle lookup directly from the Firefox address bar.

Target Browsers: Firefox Desktop (Latest) & Firefox for Android.

Issue / Question:

Address Bar Search Parameter Dropping: When users add regchecker.co.uk as a custom search engine in Firefox Desktop, performing a quick lookup via the address bar (e.g., typing reg AB12 CDE) occasionally drops the URL-encoded query parameters when redirecting to HTTPS, resulting in an empty input field.

Firefox Android PWA Manifest Issue: On Firefox for Android, the PWA "Add to Home Screen" prompt fails to register our Web App Manifest icons properly, whereas it works smoothly on Chromium-based engines.

Steps Taken So Far:

Verified OpenSearch XML validation standards.

Ensured (regchecker.co.uk) has valid TLS 1.3 certificates and proper CORS headers.

Tested on Firefox Developer Edition with clean profiles.

Any insights on Firefox-specific OpenSearch URL encoding rules or Web Manifest requirements would be greatly appreciated!

Thanks in advance!
