I'm on Ubuntu (LTS) FF 145.0.2

The audio plays fine, but the video (youtube) freezes like every 40s or so. Playing videos in MPV or Brave is flawless. I dont see extra ordinary CPU activity or anything obvious.

Ideas why this could be?

After Installing new system on my laptop and singing in to my Mozilla account nothing was restored from it. Everything is empty as it is completely new account but I created this one few years back and never had a problem with a sync. Hopefully it will be restored since I had large amount of important bookmarks. If you can check and resolve it please. Thank you.

S.M.

We have two computers in our house -- one connection. From my computer I sent something to my daughter, the second computer in our house. For some reason, my whole Facebook account transferred to her computer ad she is unable to use her own Facebook account. We have no idea how this happened. Can anyone help? Thank you . .

I am experiencing an issue where Google.com (other google domains work fine) will not load in Firefox, resulting in an infinite loading loop. Other browsers on the same system (Brave) work fine.

Here are the steps I have already tried:

Reinstalled Firefox completely

Removed Firefox via sudo apt remove --purge firefox -y

Cleared all user profiles and caches: ~/.mozilla/firefox, ~/.cache/mozilla, ~/.config/Mozilla

Reinstalled via Flatpak

Tested network connectivity outside Firefox

curl google.com works correctly

DNS resolution works via getent hosts google.com in the host system

Checked proxy settings

Ensured “No proxy” is selected in Firefox → did not resolve the issue

Tested in Safe Mode (disabling extensions)

Problem persists, so not caused by extensions

Tried disabling IPv6 inside Firefox

network.dns.disableIPv6 set to true → no effect

Cleared DNS cache inside Firefox

about:networking#dns → clicked “Clear DNS Cache” → no effect

Disabled DNS-over-HTTPS (Secure DNS)

about:preferences#privacy → “Use secure DNS” → disabled → no effect

Disabled HTTP/3 (QUIC)

network.http.http3.enabled set to false → no effect

Verified Flatpak network permissions

flatpak info --show-permissions org.mozilla.firefox shows network access allowed

Inside the Flatpak shell:

flatpak run --command=sh org.mozilla.firefox getent hosts google.com

→ returns only IPv6 address: 2800:3f0:4001:839::200e google.com

I love Firefox and it is my preferred browser. That said, I find I have to switch to Chrome or Safari on my Mac Desktop because some web pages do not display text. Doesn't happen a lot, but when it does, it renders the website unusable.

I have been to the Language and Appearance settings page, and even clicked on the Advanced tab. I have attached screenshots of my settings. What am I doing wrong? Why won't these pages display properly?

New computer upgrade from MS10 to MS 11 365. I lost all bookmarks for internet locations. How do I retrieve them? Where is the new bookmark access icon on the Firefox home screen?

I’m new to Firefox and found the Textfox theme on GitHub, which is pretty cool. However, I’m having trouble with the pinned tab size, they’re too small. It seems the theme’s creator fixed this by using Sidebery, but I don’t want to use that extension. Is there a way to change the pinned tab size without Sidebery?

BLUFF:

1. Long start up times (do not see this on other browsers) 2. FIrefox often crashes. Browser tells me that a report has been sent. To where? No response. 3. How do I check if my browser is up to date?

What could be causing this? What are my effective actions to increase performance?

When I do try to create, rename or delete a profile, I get the message, "An unexpected error has prevented your changes from being saved".

I have a new Windows 11 PC. I installed Firefox first from the Windows store and had problems adding a second profile. Now, I've downloaded the full installer and still have the problem after multiple uninstalls, deleting the appdata Firefox folder and re-installing. I've also tried to rename the FF folder after encountering the problem and just restarting FF. It seems to create a new folder with profiles, but I can't create or delete the profiles from the profile manager or from about:profiles.

I've also checked that the folders and profiles.ini are not in read-only. I've also tried to manually create profiles or create profiles using the command prompt. Nothing seems to work.

The operating system is Windows 11, and the following content is configured in the HOSTS file on the C drive: 192.168.10.10 www.simon.com 192.168.20.10 www.simon.com There are two private network servers providing website services, with server A's IP at 192.168.10.10 and server B's IP at 192.168.20.10. Then use Firefox to browse the website www.simon.com and set up Firefox's network.dnsCacheEntries、network.dnsCacheExpiration、network.dnsCacheExpirationGracePeriod Three configuration items are 0. When accessing normally, www.simon.com points to 192.168.10.10. When the 192.168.10.10 server fails, will it redirect to 192.168.20.10. What is the latency for switching domain names in Firefox? What is the mechanism for switching?

Using latest Firefox browser, when I open Google and want to ‘paste’ a word, it will not let me. Instead I get this default message, that I can’t delete. I can type anything I want, but I can’t ‘paste’ a word or words. How to fix please? HP desktop PC Windows 11 64 bit I see there is a 'new' (to me) AI mode icon in the 'same' search window as where you type on the 'right' of the search box. Maybe I just haven't noticed because I didn't have an issue before.

Thanks in advance for any suggestions

When I use Gemini 3 visual layout function to generate a homepage-like page, but Firefox cannot show any content of the result. It works fine in Microsoft Edge and Google Chrome.

My bookmark features has stopped working. When I click the star, it does not turn blue and I cannot bookmark anything. Is there a fix? I have stuff in the bookmark area and would not like to loose it.

How do I set up Firefox to remember my login security approval for websites (for instance JPMorgan Chase Bank). Chase Bank used to remember, but now I have to verify my identity each time I log in to Chase Bank.
