Every time I launch Firefox, it attempts to connect to a number of domains automatically; some of which, it strikes me, may not be entirely necessary and should, therefore, not be automatic.

For instance, I have automatic extension/plugin updates off by default, so why does FF try to connect to versioncheck.addons.mozilla.org and/or versioncheck-bg.addons.mozilla.org every time I launch it?


How many of the following do I actually need to give a pass to in my firewall and how many can I safely block?

I appreciate that a couple (e.g. githubusercontent) may be related to specific extensions/plugins, but the majority are from Mozilla/Firefox, so what what is each of them for, specifically?

aus5.mozilla.org ciscobinary.openh264.org content-signature-2.cdn.mozilla.net example.org firefox.settings.services.mozilla.com ipv4only.arpa publicsuffix.org push.services.mozilla.com raw.githubusercontent.com redirector.gvt1.com services.addons.mozilla.org versioncheck.addons.mozilla.org versioncheck-bg.addons.mozilla.org


Thanks.

Hello folks,

I had 1025 tabs open in FF, in various groups using SimpleTabGroup. Somehow I've managed to get into a situation where, when I start FF, I get just three or four of my most recently used tabs on startup.

I have no idea how to get back to the 1025 tabs I really want, but when I close FF I'm asked whether I want to close 1025 tabs, so hopefully they're still available somehow...

Any advice gratefully received!

Thanks in advance.

NB: Firefox 103.0 (64 bit). Xubuntu Linux.

I'd like to import my Seamonkey profile data to Firefox, but Firefox doesn't recognize Seamonkey or its data. How can I do this? I'd like to keep my Firefox data synced to Seamonkey, and maybe synced the other way too. And I'd like Thunderbird to be able to sync to the Seamonkey email data too, for what it's worth. I thought the importing of data when Firefox starts would take care of importing SM data but it doesn't. Are there any commandline options for running Firefox that would get the importing done? I sure don't want to mess around with a huge html bookmarks file and there's other data in Seamonkey besides bookmarks that should be imported too. Help!

Firefox is currently unusable on my system as I get the message "Gah. Your tab just crashed." for every website I try to access. Troubleshoot mode doesn't work. They don't register as crashes. I also tried uninstalling and reinstalling and that doesn't work either. I am using Firefox under Pop! OS.

Hi,

first of all thank you all in the community for your amazing work on Firefox!


I have cloned my $HOME (including ./.mozilla/firefox/) to another Linux device.

Now I realize that changing the Firefox Sync device name on the new device would also change it for the other device when checking "Connected Services" https://accounts.firefox.com/settings. I also can only see the new device name when using "Send to device" from any device.

I guess I have to unlink my new device and somehow assign it a new device ID for Firefox Sync to recognize the new device. How can I do that?

Sometimes, if the computer is offline and Firefox is open, when the computer goes back online Firefox can't connect to any website, with the page "Hmm. We’re having trouble finding that site.". The only fix is to close Firefox and open it again. Going offline doesn't always do this, and while I'm not sure of what exactly causes this to happen, a way to easily reproduce it is:

  • Turn off the Wi-Fi;
  • Reboot the computer;
  • Open Firefox;
  • Turn on the Wi-Fi;

After the computer is connected, refreshing the page sends you to "Hmm. We’re having trouble finding that site.". You have to restart Firefox.

A way that doesn't 100% reproduce it, but works enough times, is to reboot the computer without turning off the Wi-Fi, and open Firefox as soon as possible (before the computer manages to connect to the router, which is the part that isn't always consistent). Rarely, it happens after suspending the computer, or after a disconnection due to an unstable connection. I can reproduce it in Firefox's safe mode. I have a hunch that maybe this is related to networking drivers.

I'm using a Lenovo IdeaPad 5 14ARE05 (Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)), Linux NixOS 22.11 (I don't know about Windows).

Ask me for any log you might need.

This is kinda a duplicate of https://support.mozilla.org/en-US/questions/1078253, except that their solution does nothing to me.

I can't recall if this problem occurs all of the time or not. The problem is this.............when buying something online or donating online using a credit card I often get the message...."Save credit card number-choose Yes or No" or something to that effect. Is there a way to modify the settings on my browser so that I do not get this question about saving my credit card number? Or is this an issue with how the website I am browsing at works and therefore I cannot make a one-time fix? Thanks.

I am using Linux and the latest browser 103.0.1

Firefox just locks up. The mouse cursor can be used to resize the window, but is otherwise unresponsive, except to to minimize, maximize or close the window. If I click minimize and then restore the window, Firefox will have executed the last mouse-click before minimizing. This happens after five minutes or so after starting Firefox, whether I have only 4 or 5 tabs open, or a whole pile of tabs. All I can do is click X in top RHS, and then restart Firefox. Then click the "recently closed tabs" to get back to where I was. I have tried clearing the cache and (most of) the cookies. As well I did a complete refresh of Firefox, and disabled all the add-ons, but the problem is still there Running on a (old) Lenovo Thinkpad E545 with 16GB, Ubuntu in a SSD using a 50 GB partn with 30GB free. This problem occurs only in Firefox- all other apps continue to run!

OS: Pop!_OS 22.04 LTS Firefox: 102.0.1

I have the above version of firefox installed on my machine. I had noticed that automatic updates weren't being installed and did a little digging. I removed the policies.json file, ran `sudo apt update` and `sudo apt upgrade`, and checked the software update store on my machine. None of these suggestions resolved the issue. I then noticed that whenever I would select `Automatically install updates (recommended)` and close firefox that the change would not persist.

I'm not entirely certain what the issue is at this point and any guidance would be much appreciated. Thanks in advance for your help!

What does the popup message 'Pending update of Firefox snap. Please close the app to avoid disruptions.', mean because that message doesn't give enough information to figure out what it means. I got that before when the last update happened and after that update every time I boot FF can't restore my tabs but I just click try again and it always works. Since I am getting the message again I thought I would try asking on the FF forums to find out what it means and maybe get the boot problem where FF can't restore the tabs when it first starts up fixed.

Hello,

as the title suggest, all of a sudden, firefox redirects all requests to https for a certain subdomain (I haven't found any other domains yet, this one I'm checking daily and noticed this). Subdomain I'm referring to is hosting prometheus, alertmanager and grafana, all on different ports on same subdomain. Only grafana is configured to use TLS, prometheus and alertmanager was never configured and was using plain http.

All of a sudden, this morning, alertmanager and prometheus are being redirected to https. Their configuration was unchanged for months. When i open Developer Tools and visit the alertmanager or prometheus page, i get no HTTP status code (literally i get blank value under "Status", GET is trying to use https without any 302 or other redirect requests. Which gives me thinking - this redirection comes from firefox for some reason..

When opening same URLs under Private Browsing i get no issues, also , i get no issues when accessing the URLs from other browsers.

What might've happened for firefox to trigger this behavior , and how to fix it and prevent it from ever happening again.

Things I've tried: - Clear site preferences from History - network.stricttransportsecurity.preloadlist to false - browser.fixup.fallback-to-https to false - dom.security.https_first - was already false - I haven't installed any new extensions and I'm not using DuckDuckGo Extension - Enable DNS over HTTPS was already disabled

What i haven't tried: - Clearing entire history with cache and cookies. Seems like an overkill for something that should not've even happen and for something that previous options should already fix.

Please help me out.

I want to see a response in a formated/pretty way to check for errors on my work. According to this link https://firefox-source-docs.mozilla.org/devtools-user/network_monitor/request_details/index.html#network-monitor-request-details-response-tab it should be possible to do so, clicking a button which formats the response in the network part of the devtools, however this button does not exist on my devtools. In chrome there is the preview tab that shows the response in the way I need, and also as the button to format the response in the response tab. Is it a bug on my end? If not, why is it that way?

I have discovered a bug in the Sync. While starting a fresh copy of the browser and signing into the Sync, the content that was earlier saved to the Sync server is not fully restored.

As example, I use the "Preferences".

Some settings, like for example: "network prefernces", "search", etc., instead of beeing restored from the Sync server, are set to the default values and need to become changed manually into the prefered values.
