Firefox Support Forum

An old question but seems like the about:config parameters have changed recently. the following don't exist anymore : toolkit.cosmeticAnimations.enabled ui.prefersReducedMotion

I've searched with other keywords but couldn't find the new one.

Hello,

Until recently, I was able to have Firefox automatically clear all my cookies at the end of a session, EXCEPT for the cookies for websites that I had specified. This was possible by:

• Checking the "Delete cookies and site data when Firefox is closed" option under `Privacy and Security > Cookies and Site Data`
• Setting the websties that I would like to keep cookies for, under `Privacy and Security > Cookies and Site Data > Manage exceptions`

Now, I simply can no longer use this feature. If I try checking the "Delete cookies and site data when Firefox is closed" option, then quitting Firefox, it seems to insist on unchecking the box, then changing another section of my privacy settings. Namely the `Privacy and Security > History > Clear history when Firefox closes` section becomes checked, and inside, `Cookies` is marked as something to be cleared at the end of each session. This is unhelpful, because checking the box here means that any exceptions I set in the aforementioned section is not respected, and ALL cookies are deleted.

Am I doing something wrong? If there is a way to get it back to how it used to behave, that would be greatly appreciated.

Thank you!

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.

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

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?

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?

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?

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.

There is not "Usability" topic. Hence selected "Other".

Containers are one of those features that I use almost in every Firefox session. It clearly segregates my office and personal work. I am asking for a feature, that could already be there somewhere in the advanced configuration (about:config).

Before asking let me set the context. Before containers, I used profiles to separate my work. But the disadvantage of profiles is that the cache, auto-fill, history all those convenient features are not the same everywhere. But the advantage of profiles is that every shortcut key, clicking of link would open in the same work area profile. I don't have to open context menu and select a profile each time.

"Container Windows" could be such a feature which is best of both worlds. I am not aware if this is already there. At least the feature is not obviously visible. There is a feature in "multi-container plugin" which can move all the tabs belonging to a container to a separate window. if we add a feature, in this plugin or Firefox core, to bind a particular window to just one container then it can bring all the goodness of "profiles" and we can still use all the features of "containers".

1. Clicking a link in other application would open the default container (no-container) window 2. Control+Click, by default, opens tab in a bound container window, and hence in the same container 3. Context menu in all windows (bound and unbound) still gives an option to open tab in any container

Please let me know how to do this, if this is already implemented. Or tell me where to raise this feature request.

Hi I have been experiencing rejection of access to many legitimate Web Sites. I have attached the error I get even when trying to get to a mozilla web page. This is getting both frustrating and limiting in my desire to support, which I do, Mozilla's strategy of privacy and freedom.

I am using Fedora Linux Version 34 and Firefox Version 100.0.2 64 Bit. I did not experience these problems months ago. I have kept everything up to date as far as I can with my OS limits, if any.

I want to examine what is going on and would like to know where to look. Any help would be appreciated ... Robert

Since i have my new laptop, i do not get twitter videos, bbc news working. Youtube and vimeo does work! Guess its about html5? Have checked mediasource and javascript settings in about:config and they are okay. Do not have this problem in brave browser.

Anyone has an answer?

Thanks in advance!

Today, web pages started showing small numbered boxes behind each element on a webpage. As you move down the page, the numbers are in sequence. I tried the font settings. They are all set at what they should be. I also tried the config settings, no joy. If I restart in troubleshooting mode, the boxes go away. Note: I am using Linux Mint, and Firefox just updated yesterday to V103.0.2. Any help would be appreciated.

Firefox unter ubuntu 22 hat keinen Zugriff auf die lokalen Dateien (z.B. /usr/share) Der 'open' auf '/usr' scheitert mit 'read'-Zugriffsrecht.

Ganz egal, was in '/etc/apparmor.d/usr.bin.firefox' respektive in '/etc/apparmor.d/local/usr.bin.firefox' spezifiziert wird, das Zugriffsrecht für '/usr' ist immer 'read'.

Wie kann man auf die Dateien unter '/usr/share' zugreifen?

Mit freundlichen Grüßen

Thomas

Firefox crashes (tested in troubleshoot mode) for this URL : Link which causes crash https://developers.google.com/android/guides/opensource#java

There are no crash logs generated either (checked in about:crashes) . Attaching a post-crash dialog screenshot

I have my saved login and password details from another browser in a CSV and would like to import them to Firefox. I initially did not have the 'Import from a File' option in the drop down menu of the Logins and Passwords tab. After following a guide that instructed to set signon.management.page.fileImport.enabled to true in the about:config page, the option appeared. However, the said option is unresponsive to any clicks. The drop down menu simply closes once the option is selected, without any other reaction.

I'm not sure if this is a related problem but I am also unable to use the Import Wizard that appears on performing Alt+F and choosing 'Import From Another Browser...' The Import Wizard window only appears with a message that says "No programs that contain bookmarks, history or password data could be found."

Firefox browser version: 103.0.2 (64-bit) OS: Ubuntu 22.04 (64-bit) Windowing System: Wayland

Funnily enough, the 'Browse..' button for adding images under this support question doesn't work either.

i am using Firefox Snap version 103.0.2 (64-bit) on Ubuntu 22.04. Whenever I try logging in to twitter, It shows a blank screen after I press login button after entering the password (Image is attached). I can login to other browsers I have installed on my laptop.

I have tried removing cookies of Twitter.com several times and even reinstalled snap version but the issue is still there. Any fixes for this? I can't keep switching browsers just for using twitter.

I am attempting to import server certificates into Firefox. But the "Import" button does nothing when viewing certificates. Any work around? I need to import our server certificates into the Authorities section.

Ubuntu 22.04 Firefox installed through snap. Version 104.0 just upgraded this afternoon.

Thank you, James

Hello, I'm currently running firefox developer edition and i'm facing a weird bug: When firefox is started, opening a web url from outside of firefox window does'nt work and display error message: "Firefox is already running but is not responding...". It expects that i close all instance of firefox instead of just opening url in a new tab.

Do you have any idea?

I'm working on version 105.0b2 with two profiles on an ubuntu 22

When Clicking on the xkcd random button, I am led to an error page, saying: """The page isn’t redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies.""" This is unaffected by turning off tracking protection. This may be an error with the page Steps to reproduce:

- go to xkcd.com
- click on the button labeled "Random"
