Every time the browser autofills a password it asks me for my Windows password. I don't want this behavior, as this makes password autofill completely pointless. How do I disable this "feature"?

So, my problem is with HW acceleration in FF. Basically:

If its enabled: It causes graphical artifacts in videos [See screenshot]. If its disabled: It brings screen tear in to videos and autoscroll [Like if Vsync is disabled in games].

I tried safe mode, I tried reinstall of FF, I tried disabling and enabling extensions. I tried to set Vsync on in Nvidia control panel... the only thing that impact those bugs is HW acceleration in FF.

My drivers are up to date, my browser is up to date, yet there is such trouble.

Any ideas or solutions?

When I go to view an already open tab it will sometimes randomly move it to the very end of my tabs all the way to the right. I don't want it to move tabs without my intervention. Clicking on a tab should keep it in place.

This has been an issue for about 2 months now. I'm not sure what's causing it or even if it's entirely a Firefox issue as I have noticed something similar happen in another program with tabs that I use often. It still seems like a Firefox issue in that moving a tab all the way to the end is a very specific task that can't normally be done accidentally.

Is there a way to prevent this from happening or has anyone figured it out?

I have not changed any settings related to fonts in firefox (running on windows 10 desktop), but I have this issue where flag emojis are displayed as a letter code on the page itself, but still display correctly in the tab at the top. is there a known fix for this?

when I play a product video on amazon, I get the following error. I don't have a problem with another browser.

The media playback was aborted due to a corruption problem or because the media used features your browser did not support. this is a linux mint desktop.

thanks.

For days I have been seeing Firefox be very slow to load a page (as in minutes) or stop working entirely. At the same time Chrome works fine. Mac Mail has become intermittent as well. I have uninstalled Norton products and changed Network proxy settings many times. Nothing helps. I have created new profiles. I switch between profiles. I have hacked into my WiFi router. Nothing, nothing helps. Safari hangs up too. Firefox on my android phone continues to work properly when using my Wifi router -the same router my Mac Studio connects to the internet with. I can access my third party mail service via Firefox on my android phone. Both FireTV devices work. I am at my wit's end. At this point I have shifted all of my work over to Chrome.

I have cleared caches. I have gotten rid of all cookies. I have restarted Firefox and rebooted my computer countless times.

Hello, I have a web application that can send a base64 data, it crashes in mswsock.dll when data is big than 3Mo. I don't face this issue on other browsers. Appreciate in advance your help.

I created a tab group and saved it. After saving I confirmed it was inn the toolbar location. I used it this morning successfully. Just now I closed all my tabs in order to shut down. Doing so eliminated the tab group. It is no longer available from the toolbar. What happened?

A few weeks ago I tried installing a Pi-Hole (hardware-based network level ad blocker), removed it shortly thereafter. Since then, I've been getting the "Our systems have detected unusual traffic from your computer network" screen whenever performing a Google search from Firefox in Private mode, either from the toolbar or from the website. It only happens on Firefox (nothing from Chrome incognito windows), only happens in Private windows, and recurs every hour or so within the same open private window.

I've tried everything to reset my system to baseline to root out the issue, but I'm getting nowhere. Things that haven't worked:

• setting all VPN and proxy settings to off
• ensured all DNS settings are set to automatic
• renewing IP (IPv4 and IPv6, via command window and leaving router/modem unplugged overnight and verifying new dynamic IP assigned)
• clearing all browser data (cache, history, cookies)
• disabling all extensions (Ad Block Plus is my only extension)
• refreshing Firefox (about:support > refresh Firefox...)
• hard router reset
• different network device
• multiple malware scans (all clean)

Is there anything specific to Firefox and how it handles Private connections that might be throwing a wrench here? I'm pulling my hair out.

Hi Team,

I’ve successfully built Firefox v135 from source on our internal development RISC-V64 platform running on Ubuntu 22.04 with GNOME 42.9 (Xorg & Wayland), Our RISC-V Development platform does include a GPU HW which support HW Acceleration for GNOME & other 3rd Apps (Supporting X & Wayland), and Work seamlessly without any issues.

The FireFox v135 Application (via ./mach run) starts up normally. But the major issue I'm observing is that Firefox browser is very slow and laggy, especially during search operations and video playback on YouTube I see a poor performance. Upon further check I found that the most of the work is getting done over the CPU and the utilization is quite high, which is causing the FireFox to perform poorly. I also did try to switching to "Use hardware acceleration when available" in the Mozilla FireFox Settings, but still there is no difference with or without this check and Mozilla FireFox browsing Experience is very poor.

Kindly do let me know how we can enhance and improve the overall performance of FireFox Browsing Experience on my RISC-V platform. Any Support and Help is highly appreciative!

Attached a Build Steps and Configuration used for building Mozilla FireFox v135 on my RISC-V64 platform, let us know if there is anything missed. Thank you!

**BUILD STEPS**

1. Clone the Firefox source (v135.0.1):

git clone --branch FIREFOX_135_0_1_RELEASE --single-branch --depth 1 https://github.com/mozilla-firefox/firefox.git cd firefox

sudo apt-get update sudo apt-get install -y curl python3-dev libnspr4 libgtk-3-dev llvm-14 llvm-dev clang libclang-dev libx11-xcb-dev libevent-dev libdbus-glib-1-dev m4 libnspr4-dev meson

3. Install Rust:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh source $HOME/.cargo/env

4. Install Python and Rust-related tools:

pip install --upgrade pip pip install uniffi-bindgen referencing==0.29.1 cargo install cbindgen

5. Apply the RISC-V compatibility patch:

patch -Np1 -i firefox-riscv64-hack.patch

6. Create the mozconfig file with custom build options:

ac_add_options --with-app-name=firefox ac_add_options --disable-release ac_add_options --enable-hardening ac_add_options --enable-rust-simd ac_add_options --enable-linker=bfd ac_add_options --disable-bootstrap ac_add_options --enable-official-branding ac_add_options --with-branding=browser/branding/official ac_add_options --enable-update-channel=release ac_add_options --with-unsigned-addon-scopes=app,system ac_add_options --allow-addon-sideload ac_add_options --enable-default-toolkit=cairo-gtk3-wayland ac_add_options --with-system-zlib ac_add_options --disable-strip ac_add_options --disable-install-strip ac_add_options --enable-system-ffi ac_add_options --with-system-libevent ac_add_options --with-system-nspr

1. ac_add_options --with-system-nss

ac_add_options --disable-updater ac_add_options --disable-tests ac_add_options --enable-alsa ac_add_options --without-wasm-sandboxed-libraries

7. Vendor Rust dependencies:

./mach vendor rust --ignore-modified

8. Upgrade Cairo from 1.16.0 to 1.18.4:

1. Extract and build Cairo 1.18.4

tar -xvf cairo-1.18.4.tar.xz cd cairo-1.18.4 mkdir build && cd build meson .. --prefix=/usr/local ninja sudo meson install

9. Build Firefox:

cd firefox ./mach build

The "import bookmarks" doesn't work on my ubuntu 24.04.2 LTS running on an old macbook air. I exported bookmarks from my chrome. when i try the import from file, it says "bookmarks exported successfully", but the bookmarks don't show up anywhere. attached screenshots. what am i missing? thanks, Nilesh

Sucessfully installed Firefox 139.0.3 armv7 nodpi on an Android 5.1 tablet device, but no matter what website I try to access (even Google), a plain black screen is always displayed. Homepage and Settings page works fine, even those history thumbnails are showing the website correctly. If I click on the address bar to type something, it then suddenly changes from black to the actual website for a blink of a second and then gets black again.

Is there a way to fix this? Firefox Focus, Beta and Nightly behaviors the same. I already tried to uninstall and clearing data/cache. It seems a bug with this specific tablet device I am using even though it shouldn't, since Android 5.1 is still supported, isn't?
