Firefox Support Forum

Firefox is showing all the time "The connection has timed out. The server at xxx.localhost is taking too long to respond." on loading or changing pages on localhost. When calling the same URL everything runs smoothly using Chrome.

Environment: Firefox 111.0.1 / Ubuntu 24.04 / Apache/2.4.56

Which settings can I change in Firefox in order to solve?

I found that when starting Firefox on my school's WiFi, it starts up very slowly. Using `strace`, I found that it was taking it's sweet time making a DNS request to try to resolve my computer's `/etc/hostname`. After searching the Firefox source code with https://searchfox.org/mozilla-central/source/, I found that the only occurrence of `/etc/hostname` was in [SandboxTestingChildTests.h](https://searchfox.org/mozilla-central/source/security/sandbox/common/test/SandboxTestingChildTests.h). So I was wondering if it's possible to disable these tests when Firefox starts up.

Suddenly my email from yahoo (my address==> [edited] @att.net) is GOING INTO TRASH. What'up ? I made NO changes to filters.

Thank you

Not sure if this is something everyone experiences but every time Firefox updates on my computer, the password manager goes back to default settings and starts prompting to save passwords again. I have disabled the darn thing countless times, but it always comes back alive after the browser restarts after an update. Why does this setting does not persists after an update and stays disabled? I have a Firefox account, and sync is on.

The refresh button (circular arrow has gone from the toolbar It is not present in the customise list It is restored if I I select 'restore defaults' but is only there for the current session and not when firefox restarts So how can I add the restore button PERMANENTLY please

Hi Forum Folke,

This switch from Windows to Linux has been mostly disastrous, with my exported Tbird profile zipfile turning out to be corrupt and not openable, and now I can't import my saved bookmarks file either. I can open it and read the list, I can even open it in Firefox and click on any link in there and it opens in Firefox, but they simply will NOT import.

If I understand the process correctly, go to bookmarks > manage bookmarks > Import and Backup, "Import bookmarks from html..." If I click on this, it opens the file manager, and I navigate to my backup drive and click on the "bookmarks_3_24_23.html" file, then click on "open." This *should* start the import process, and then they should show up in my bookmarks, no? What it does is exactly nothing at all. The window freezes for a moment (unresponsive to any clicks), then does respond to clicks, but there are no imported bookmarks anywhere.

If I enable the bookmarks toolbar, the first button is "Import bookmarks," and if I click on that, it just tells me "No programs that contain bookmarks, history, .... can be found."

I tried dragging and dropping the file into a new tab, and it added "bookmarks_3_24_23..." to the bookmarks toolbar. I can click on it and the list opens in the tab, and I can scroll down and find and open links... but that's obtuse and awkward. I'd much rather have Firefox import the bookmarks and display them normally.

What am I missing here? I've done this before without any issues, doing exactly the same things, but this time it's a no-go. I'm starting to wonder if I've just got a buggy install of Linux ( Linux Mint 20.1 Ulyssa with the Cinnamon 4.8.6 desktop.)

Just went to get the current version of Firefox, and noticed that it's saying: "Updates disabled by your system administrator." Think this would apply to importing bookmarks as well?? Anyway, the version is "Firefox for Linux Mint mint-001 - 1.0" up at the top of the "about" window, and below that is "111.0 (64-bit)."

Any ideas are very much appreciated!

Every time I use Google Meet, Firefox show me a tiny orange controller over al my desktops in Fedora Linux. It is a bit annoying an distracting. Maybe could be great this icons appear in the os panel in linux.

The file you are supposed to download on page "https://www.support.xerox.com/en-us/content/146849" gives a webpage with trash, where it should open the download window . I know it's Firefox because I tried downloading that file via Opera browser and that succeeded . Dowloading zip files from the Xerox website gave no problem, only DEB files .

I'm following a tutorial to install cinnamon desktop which includes Firefox snap on my Ubuntu LXD container, but the installation with snap fails. Does anyone know why it happens and how to fix it?

A certain website (flixbus.com) is getting pinned on my firefox automatically. I have unpinned it several times but after few seconds, it gets pinned again. It's driving me nuts. I even cleared all my cookies but it didn't help.

So I have this extremely annoying issue. Almost every time I open Firefox on my system, all of my add-ons get disabled. There is no pattern to when it will happen either. Sometimes I can open it 2 or three time without a problem, other times its every single time, and to top it off all of my saved logins randomly disappear too, as well as some of the settings (namely search bar settings). A simple closing and reopening of Firefox restores the login info, but not the settings. I’ve tried making a new profile, didn’t work. Tired uninstalling Firefox and starting clean, still didn’t work. I’ve checked all my settings, and tried deleting the extensions data in the Mozilla folder. Nothing seams to work, and I don’t have a clue why this keeps happening. I’ve been using Firefox since it was still in beta, and have never had this kind of problem before. Any advice would be greatly appreciated.

Firefox 111.0

Hi. I was suddenly having unexpected problems to log in in a site (https://www.lanacion.com.ar/). So I updated FF but the problem persists. Then, I uninstalled FF, downloaded it again from the repository and installed again, but the problem persists. Then, I downloaded directly rom the Mozilla site, expand it in the desktop and double click the program icon. The program opened and I was able to log into the site I was trying to. Interesting enough, the browser opens a lot faster than when installed. My question is: everywhere on the web the response is "you have to install the program" or "the program is already installed in your distro", which is true in my case, but one day stopped to work properly. BUT I'm not installing it, and it works apparently well... ¿how can it be? Thanks in advance for your reply. -Enrique.

Hey, I'm running Arch Linux (fwiw, KDE). Some websites seem to have a problem displaying some fonts properly (see attached screenshot). Tried anything I could find online, didn't help. Most sites display normal smooth font. Konqueror and Falkon don't seem to have this problem.

In Settings → Privacy & Security → History → Settings..., I have enabled the automatic clearing of "Site settings" when Firefox closes. However, the clearing of all site settings causes the clearing of all my HTTPS certificate error exceptions (Settings → Privacy & Security → Certificates → View Certificates... → Servers). Is there a way to make some exceptions for the clearing of site settings? I would like the site settings of a few websites to be preserved, while deleting the site settings of all other sites.

Hello those wiser than me, When my Firefox 110 goes inactive by clicking elsewhere, the only change is that selected elements temporarily de-select and the scrollbar thumb turns color to one almost the same as the track, making it nearly invisible. Is there any way to keep it the same (much darker grey) when it is not the active window with the focus? There are a few themes that don't exhibit this behavior, but I could not find a dark one. My search on the subject yields only webpage design talk or obsolete pre v78 add-ons.

I'm on Linux Mint 20.3 Cinnamon with FF's built-in dark system theme. Thanks in advance.

When DNS over HTTPS is not enabled in Firefox and I set network.dnsCacheExpiration to 600 seconds, evidence from about:networking#dns shows that the minimum DNS cache expiration time is indeed 600 seconds. However, when I enable DNS over HTTPS and set network.dnsCacheExpiration to 600 seconds, the network.dnsCacheExpiration setting seems to be ignored. New DNS cache entries are able to have far less than 600 seconds to expiry. Why is network.dnsCacheExpiration ignored when DNS over HTTPS is enabled? Could this be a bug in Firefox?

In about:config, I see two settings for controlling the minimum amount of time for DNS cache expiration: network.dnsCacheExpiration and network.dnsCacheExpirationGracePeriod. What is the difference between them? They are both set to 60 seconds by default.

I am using Firefox on Ubuntu 18.04 (current release 111.0, but the problem has occured over the last two releases). I like to open the individual page from a Youtube playlist so that if I get distracted, I won't lose my place. I do this either when disconnected from the internet or using the "work offline" feature. Previously firefox would show either "Problem loading page" or "Serve not found," but now it keeps trying to load youtube which sucks up time, cpu, and memory.

These are pages that I have never been to before so there should be no record in history, but even so I have tried clearing my history and this did not help. I have tried a bunch of other sites, but Youtube is the only site that I have seen this behavior on. Attached is an example (The google page and the first youtube tab were loaded online). The shown youtube tab (second tab) and a random webpage from google (last tab) show this behavior.

Could you please help me.

Just now I recreated my firefox login password and re-logged into the firefox account. After synchronization, I did not find my bookmarks and saved logins. Could you please help me troubleshoot the problem?
