Firefox Community Forum

When I start Firefox without any internet, i.e. Airplane mode, the browser starts up pretty quickly. However when I connect to internet, either via WiFi or LAN, the startup time increases dramatically. This means that Firefox is connecting to the internet, waiting for some server to respond and then finish the launching of the browser. I have been able to figure out that Firefox connects to the following URLs when it launches.

1. cdn.statically.io
2. img-getpocket.cdn.mozilla.net
3. ublockorigin.github.io
4. aus5.mozilla.org
5. content-signature-2.cdn.mozilla.net

Please note that this is not the complete list, it is just what I have been able to figure out. There might be other URLs that Firefox connects too, which I am not aware off.

So my questions are as follows 1) How do I come to know all the URLs Firefox is connecting too, when it launches? 2) How can I check how much time does the server take to respond back to Firefox? 3) Is there a way that to stop the connection between these servers and Firefox? For example, pockets is getting shut down and I do not use pockets. So I maybe the connection to img-getpocket.cdn.mozilla.net can be terminated or stopped. OR maybe the connection to content-signature-2.cdn.mozilla.net can be asychronous and need not hold up the browser loading and so on

Hi. I installed Firefox on my old Hp, and have now taken another laptop, an Acer Aspire One and installed Firefox on that as well, but a extended support version. I am struggling to import all my bookmarks (ex Chrome) to my Acer, and in the struggle I done something wrong since Firefox on the Acer is now locked or blocked !! I am an "old Timer" and not very computer literate. Can someone help me solve these issues so that I can move away from the HP and depend on the Acer. I found Firefox easier to use as compared to Chrome, which seemingly demanded more memory from the computer.

I have "Always ask you where to save files" checked in my preferences, yet Firefox saves downloads to my Downloads folder without asking. This was working in the past, it's only recently broken.

I'm using Firefox 140.0.2 on Mac (aarch64).

Lately I installed a new PC, and tried to download FireFox and sync my data. But my data seems like a few years ago, not as new as another PC I have now. I'm sure I have logged in with same account on them, how's this happend?

Description: while viewing videos on youtube, twitch, odysee (and possibly other sites with videos), the video player may suddenly stop playing, and after that, no video in firefox can be played. Restarting the browser makes this issue disappear for a while, but i'd like a permanent solution.

What i've tried so far: Disabling uBlock Clearing cache and cookies Enabling/Disabling hardware acceleration Disabling proxy extension Disabling antivirus on PC.

I have autoconfig.js set up to run my own js file, see below. The intention is to change the keyboard shortcuts (shame that it's so difficult😃). It worked until a few weeks ago. Now it only partly works. C+J is fine. The other two succeed in deleting the existing command, and the shortcut key does nothing. Any ideas please?

// C+J = open downloads var element = document.getElementById('key_openDownloads'); if (element) {

 element.setAttribute('key', 'j');
 element.setAttribute('modifiers', 'accel');

}

// C+D = Duplicate tab var element = document.getElementById('addBookmarkAsKb'); if (element) {

 element.removeAttribute('command');
 element.setAttribute('oncommand', "duplicateTabIn(gBrowser.selectedTab, 'tab')");

}

// CS+N = move tab to new window var element = document.getElementById('key_undoCloseWindow'); if (element) {

 element.removeAttribute('command');
 element.setAttribute('oncommand', 'gBrowser.replaceTabsWithWindow(gBrowser.selectedTab)');

}

Suddenly getting persistent "Gah. Your tab just crashed" error message this week; running Windows 11 on a Lenovo X1 Carbon 12th Gen laptop; I have run Firefox in Safe mode, disbled multi-process tabs, turned off h'ware acceleration, cleared cache and cookies, turned off BitDefender, Refresed firefox, updated firefox and windows, checked for malware, reinstalled Firefox, and attempted to create a new Firefox proficle (didn't run), all to no avail; attempted to use mozregression, but I don't have the skills. Would be glad of any help! Thanks

I am not sure why every time I go to print something, it takes the color blue and turns it gold. I have used other browsers like Edge to print and it does not do this, only while I am using firefox. I have tried to set the color management mode to 0 and to 1 and neither of these options have worked. Is this a problem with the newest update or is there a setting that I am missing?

I only discovered the tab groups function within the last few weeks, and upon finding, I moved dozens of open tabs into organized groups. On using the feature, I noticed the ability to save and close groups and that I could recover those closed groups by using the arrow in the browser toolbar.

When I got to my PC this morning, my desktop had restarted or hibernated or something; when I started it up, Firefox was open which is unusual as I don't have Firefox set to open on startup - usually so I can restore sessions after crashes. All of my previously open tabs were open, but none of the closed, saved tab groups are visible. I cannot find any of the dozen or so closed tab groups and it appears I've lost easily hundreds of tabs.

I tried looking at the session backups but it seems because Firefox was open on start, it overwrote the previous session data. Is there any way to recover those saved groups or am I SOL?

When log in to some sites using Safari, it a text to me security logon code is requested, it will show up automatically on the site for me to "click" and insert.

is there a setting for this?

I'm trying to enable autofill for payment methods but autofill is not working. I've checked the correct box under Preferences --> Settings --> Save and fill payment methods. I do not need the device to require sign-in to do this. But when I try to fill in from my saved payment methods, nothing fills in. I've restarted Firefox and my MacBook Pro, but it still doesn't autofill the payment methods. This has worked in the past, but it's not clear why it's not working now even if I have followed all the correct steps. Please help! Thanks

My system has 2 display monitors, the second one used only in Photoshop and Lightroom. Recently I converted my system to Windows 11 and the Firefox display screen now comes up only on my second monitor screen. I want it back on my primary monitor where it has always been under Windows 10. Help and Thanks. Charles Klingsporn

How the heck is there still no way to modify Firefox hotkeys without an extension? Firefox must have updated because I can no longer use Command-Option-Up/Down to navigate between servers on discord.com. Instead those keys are now reserved by Firefox for navigating tabs (which seems superlative, there are already MULTIPLE other hotkey combos for switching tabs.) Absolutely bonkers that there's no user-friendly way to modify these hotkeys.

After updating Firefox yesterday, when I use the search bar, switching between my custom search engines can only be done via clicking on a drop down menu at the left end of the search bar and selecting one with the mouse cursor. Previously, I could select my preferred search engine by using the up or down keys to cycle through them while typing a search, then hitting enter when the one I wanted was highlighted. Having to switch from keyboard to mousepad while typing a search is really annoying, I found the old way much more convenient. Is there a way to revert this, and put the search engines back at the bottom of the search suggestions, where I can access them with arrow keys?

Also, when I search now, the search stays in the search bar instead of changing to a URL, and I have to click a little internet globe icon at the right end of the bar for it to show the URL. This is also kind of annoying. Is there a way to turn this off, and just set it to show the URL every time?
