Diễn đàn hỗ trợ Firefox

We want to use Firefox on a locked down system. Using the -kiosk command line argument gets us most of the way there. But they still have access to the devtools when they hit F12. It appears there are ways to disable devtools after the browser has been started. How can we disable the devtools before the browser is opened and without registry changes?

Hello When i download files it has started to put UTF-8 before the name of the file ? Why is that ? Because it doesn't do it if i try it in another browser.

My YouTube homepage is blank when I visit using Firefox (see attached screenshot). Here is a list of all of the fixes I have tried:

-Disabling all extensions and turning off Enhanced Tracking Protection (at the same time) -Clearing cache -Clicking 'forget this site' on YouTube in my browser history -Restarting my PC/Firefox -Refreshing Firefox profile (this worked, but the issue returned after an hour) -Changing my system theme to light mode -Launching Firefox in troubleshoot mode -Logging in on an incognito window (with the same result) -Probably some other things I'm missing (I tried pretty much every result I could find from looking up 'YouTube homepage is blank' and 'YouTube homepage not loading).

The issue only occurs on Firefox and only after I log in to YouTube. This has never occurred before. I checked to make sure my Firefox and YouTube settings are the same as they've always been.

YouTube videos load fine as long as I paste the direct link into the URL bar, but ONLY the video (no comments, recommended videos, likes/dislikes, description, etc...) and I can't take it out of theatre mode nor fullscreen it (fullscreening it just removes the top bar of the browser--the video itself still has black bars on the sides).

Sometimes when I reload the page, I see the following at the end of the URL: &ThemeRefresh=1. I don't know if that means anything.

I am using the Firefox app on Windows 11. I am not using a VPN. This issue is specific to YouTube and YouTube only.

Any help would be greatly appreciated. Thanks!

I made sure to sign in and hit sync on my browser prior to moving over to my new computer. I've logged in on my new computer and manually hit the sync button but my passwords and bookmarks are not populating.

Dear Firefox Team,

I hope this message finds you well. I would like to suggest a small but useful enhancement to the Firefox interface that I believe would improve user experience and accessibility.

Currently, in the "Customize Sidebar" section, the available tools are limited to a few items such as AI Chat, Tabs from Other Devices, History, and Bookmarks. I believe it would be very helpful to include "Downloads" as an additional sidebar tool.

This would allow users to quickly access their recent downloads without needing to go through the menu or use shortcuts. It adds convenience and aligns well with the purpose of the sidebar — offering quick access to frequently used features.

Thank you for your time and for continuously improving Firefox. I look forward to seeing future updates! Warm regards, Julabeeb a firefox user, developer, and contributor

Greetings...

I am a frequent user of multiple tabs whenever I use Firefox. As a result, the new Tab Groups feature interests me, primarily if it will help my to organize and manage my multiple open tabs. Initially, I have the following specific questions.

Q: Is there a maximum quantity of tabs that a Tab Group can contain?

Q: Is there a maximum quantity of Tab Groups that can be open at the same time?

Q: Does the use of one or more Tab Group negatively affect the performance of my web browser?

Q: Can a Tab Group be bookmarked? (Periodically, I need to bookmark a group of open tabs and I am currently able to do so by selecting all of the tabs then bookmarking them as a set.)

Q: Does the new Tab Groups feature represent a way to reduce the number of open tabs that appear at the top of my web browser - basically, a way for multiple open tabs to occupy a smaller space versus scrolling them across the top of my web browser?

Thank you very much for your feedback! Take care...

Hi there.

The original problem is described here: https://support.mozilla.org/en-US/questions/1472503 ( Also the solution I found.)

Jaws and James seem to have left the building.

This problem first occurred with the update from V 135.0.1 to V 136.0 . Currently on V 136.0.4, and every update has exhibited the same behavior.

I have the same issue with two laptops, running Windows 10. Each has been through a few update cycles, and the "Restart to Update" always fails.

So, I close FF, watch for the Resource Monitor to quiet down, and reopen FF.

When I go through this sequence, I notice that the screen will flash once VERY quickly before opening the home page.

FF seems to function normally otherwise.

Thanks for being there,

My laptop died and I have the SSD in a caddy connected to a spare PC. In order to import logins it looks like I need to convert the existing logins.json file to a csv. Not so keen to upload this to an online site. Tried excel to no avail. I have also attempted to copy and paste with Firefox closed. The file is there but passwords do not load into Firefox. Any suggestions appreciated.

I cannot load Firefox anymore. When I download the program for a reinstall, it only completes about 60% of the install before stopping. Is Google or Microsoft behind this??

Thanks!

I have my Windows Task Bar set to collapse when the mouse is not over it. When I first open the Firefox browser, I cannot get my Windows Task Bar to pop up when I hover my mouse over the bottom of the screen.

If I reduce the size of the Firefox window and then expand it back to full size the Task Bar will again operate normally by popping up when I hover the mouse over the bottom of the screen and then collapsing again when I move away.

This didn't start happening until after the last couple of updates.

Why there is no way for me to review or rate add-ons for the Firefox? Many years I am using Firefox and sometimes I just cant understand what a strange bugs I am facing.

New to Zen, love it. I installed in Ubuntu 22.04 and MacOS Sequoia. I set both to sync everything. Yet, even though the workspaces were synced, they came empty in the second device. Am I missing something?
