Fórum podpory Firefox

I've some search engines which was configured a lot of years ago (or maybe was imported from another browser many years ago). They are working in address bar (e.g. I can enter there "cve something", press Enter and get redirected to https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=something), but not listed neither in about:preferences#search nor in my profile's search.json.mozlz4 (I've unpacked and checked it - it contents does match about:preferences#search). I've tried to grep for "cvekey.cgi" in my profile folder but get no results (I suppose these "hidden" search engines are stored in some sqlite file).

I'd like to have these hidden search engines listed in about:preferences#search. I can even manually re-add them, but how can I find complete list of all configured search engines?

i tried to play video from sites but an error is coming "libavcodec may be vulnerable or is not supported, and should be updated to play video."

my machine already have libavcodec installed properly.

i had downloaded firefox 103 for linux from your site and extracted it then running the command firefox.

as firefox have all the required files in one folder to run firefox web browser so mozilla have to put the libavcodec in the same folder.

i have another web browser installed from other firm and they provided me the media codec separately as per my requirements and it is working very fine.

so mozilla also have to provide me the media codec separately or put the media codec in firefox distribution package.

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?

Thanks.

everytime I open firefox, it automatically switches tabs like these which require authentication to log in. even though their password is saved, I am still required to click in sign-in button.

Its really annoying that these kind of tabs get opened automatically, and then I have to switch back. Is there a way to disable this autoswitch or better, let the authentication happen automatically since the password is already stored ?

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.

Zorin16-Linux version 99.0 Ubuntu Canonical 1.0, -found in Help/About. Firefox recognition of version below says 91.0. Also have Linux Mint 19.3 (Tricia). Computer 15YO Dell Dimension 900.

I've had no problems with Linux Firefox for many years. I do not use any other Non-Linux OSes. Linux Mint updates Firefox regularly and so do I in that OS. I'm currently in a free version of Zorin which doesn't seem to push out updates, so my Zorin Firefox may be sadly out of date.

At any rate, today in Zorin, when I went to several of the bigger online sales platforms, they refused to accept my Firefox and suggested Chrome, Opera, and Safari; Target suggested Firefox.

Went to Mozilla to try and upgrade, but it didn't offer the Linux browser automatically when it read my computer. I was only offered the Windows browser. This may be because the computer is an old Dell Windows machine that I converted to Linux or it may not. I've never had this happen before.

Yesterday in Linux Mint, in which Firefox is upgraded at least weekly, the same thing happened once with a big online retailer. They said my browser was outdated and unsafe.

What's going on? I'm wondering if Linux OSes are simply not being accepted when the big retailers are doing software upgrades, or is something going on with Firefox?

Since upgrading to Firefox 103.0.1 on Linux Mint I am noticing that clicking on the URL bar or typing anything into it now adds "Search with Google" and "Search with Amazon" in the dropdown URL suggestions. This is unwanted behaviour since I have those search engines disabled.

In searching for an answer I found some old suggestions such as setting browser.urlbar.unifiedcomplete to false. However this no longer works.

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.

Maximizing and minimizing are still normal, but Firefox windows could not be dragged now.

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.

Hi.

I have been experiencing audio problems in Fedora's Firefox when gaming in some web sites like <kbhgames.com>. An example happpens in <https://kbhgames.com/game/dragon-ball-advanced-adventure>.

All goes well on a 64-bit Debian Buster's Firefox 78.14.0esr. The problem is about a 64-bit Fedora's Firefox 94.0. And yes, the issue is there even when all permissions are loosen.

Besides optional troubleshooting Information being shared, common specs are below for convenience:

* user agent Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:94.0) Gecko/20100101 Firefox/94.0; and

* Kernel (according to uname) Linux charger-rt 5.14.18-200.fc34.x86_64 #1 SMP Fri Nov 12 16:48:10 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux.

Hi everyone,

a long time ago, Firefox on GNU/Linux didn't have this default behaviour I've described in the title of my question (but FF on Windows had this behaviour at the time, so I believe it was decided to unify the behaviour on all platforms).

The thing is: I truly dislike having the existing text selected automatically. When I click a precise location in the URL or Search field (where some text already exists), I expect the text cursor to locate at this exact spot, NOT the existing text to be entirely selected! With this "new" default behaviour, it now requires 2 clicks to achieve the same task (not what I'd call an improvement) and makes it really PAINFUL to construct a list of search terms (one by one) by copying/pasting them from the current web page (funnily, it proves to be less painful when copying text from another application, since the automatic selection of previously pasted search terms does NOT happen when pasting an additional term -> this is exactly the behaviour I'm expecting).

Historically, whenever I was willing to have the existing text SELECTED (I agree this can be useful from time to time), I used keyboard shortcuts Ctrl+L or Ctrl+K to move the text cursor to the URL or Search field (respectively).

All in all, the historical behaviour of FF on GNU/Linux was just fine (at least to me).

So my QUESTION today is: how to get this historical behaviour back? How to prevent the existing text from being selected when I just CLICK in the URL or Search field?

I've not been able to find a hidden option to configure this behaviour since FF on Linux changed the rule. So I'm afraid it doesn't exist... But if so, would it be possible to add such an option?

Thank you :)

firefox-104.0b6 has the "......error while loading shared libraries: libatomic.so.1" error on recent debian versions/current stable kernels Debian 5.10.28.

firefox-102 and 103 got rid of this error but about a two years ago the newest ff developer editions had this problem also.

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

Until FF100, I used to disable <Ctrl><W> (close tab) by modifying browser/omni.ja, commenting the following line out in chrome/browser/content/browser/browser.xhtml :

<key id="key_close" data-l10n-id="close-shortcut" command="cmd_close" modifiers="accel" reserved="true"/>

It worked until FF100, but doesn't work anymore in FF103 : commenting that line out seems to have no effect on <Ctrl><W>.

Does anybody know why ? Or does anybody know a way to disable <Ctrl><W> ?

Background : on French keyboards, the <W> key is right next to <X>, so when I try to do a cut/paste (<Ctrl><X> → <Ctrl><V>) I sometimes end up doing <Ctrl><W> by mistake, thus closing the tab. Re-opening the tab doesn't always do the trick, sometimes the latest work is lost.

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!
