Firefox 技術支援討論區

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.

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.

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!

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

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.

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'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?

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 ?

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?

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?

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

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.

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!

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.

This was going to be a question about Firefox being unable to display the file picker dialog, but I managed to find a solution that worked for me along the way. Since it was nowhere near the top of Google's results, I thought I'll share my solution in the hopes that this would help someone facing this same issue.

The hardware:

• Asus UM425IA Zenbook (AMD Ryzen 7 4700U CPU)

Worked in:

• Ubuntu 20.04 LTS
• Firefox provided by APT repository
• Xorg display server

Not working in:

• Ubuntu 22.04 LTS
• Firefox 99.0.1 provided by snap
• Wayland display server
• File picker worked briefly on fresh install, but something (not sure what) quickly breaks file picker functionality

The symptoms:

• Firefox stopped being able to open file picker dialogs
• Right clicking an image and selecting "Save Image As..." does nothing
• With forms that accept file upload (such as on this post question page "Add images (optional):"), clicking "Browse" does nothing
• File downloads work correctly when set to "Save files to ..." under Settings, but nothing happens when set to "Always ask you where to save files"
• No response to "Ctrl + O" open file shortcut

Similar questions and solutions:

• Fixed by reinstalling Firefox
• Fixed by resetting Firefox
• Fixed with a restart on a Mac
• Fixed by downgrading to Ubuntu 16.04

Things I tried that did not work:

• Disabling hardware acceleration
• Starting with add-ons disabled
• Troubleshoot mode
• Clearing startup cache
• Clearing cookies and site data
• Clearing history
• Refreshing Firefox
• Creating and using a new profile
• Deleting the `xulstore.json` file from the profile directory
• Toggling all permissions under Ubuntu Settings > Applications > Firefox to off and then back to on
• chmod 777 ~/Downloads
• Disabling native file picker "ui.allow_platform_file_picker = false"

And finally, what fixed it for me was to go into "about:config" and change "widget.use-xdg-desktop-portal.file-picker" from "2" to "0". Credit to this post that clued me in.

I really hope this saves someone else 2 days of hair pulling and I would appreciate advice from someone more knowledgeable than me on:

• Why this fixed the problem
• Whether I should be opening a bug report either against Firefox, or Ubuntu
• Whether I should also be changing "widget.use-xdg-desktop-portal.mime-handler" and "widget.use-xdg-desktop-portal.settings", both are currently set to "2"

Hello! My Firefox version is 91.11.0esr Several months ago Firefox starts behave this way. It's much more convenient when speaker button always appears on tab. It's absolutely incomprehensible why developers did it with Firefox. Who likes to waste time searching for noisy tab. I wish it work like before.

There is a specific challenge that i am facing with Firefox and some of the solutions that i have tried is not helping me to resolve the issue.

What's the issue: There are double spaces issue in Firefox

Where is it : 1) Menu 1.1) It's in the Menu New Tab is seen to me as New Tab (more spaces are for demonstration only) 1.2) All the Menu items which have space are show with more then one space including

  1.2.1) File Menu -> New   Window (and all the drop down menus with spaces)
  1.2.2) Edit Menu -> Select     All (and all the drop down menus with spaces)
  1.2.3) View-> Page     Style (and all the drop down menus with spaces)
   1.2.4) All the rest of the menus where ever there is a space there is a double space

2) URL : I type something in the URL and they are double spaced "this is test" will look like "this is test"

   THIS URL looks to be double spaced on firefox https://support.mozilla.org/en-US/questions/1338204?page=2
   like below

3) Numbers in the browser :

   Any number displayed is double spaced in the browser output (most of the times, most of the web pages)
   
   

4) Bookmarks : All bookmarks are double spaced

5) Settings:

Settings: I have tried some suggestions below and they did not work for me.

browser.proton.contextmenus.enabled browser.proton.contextmenus.enabled is still set to false but seems to have no effect toolkit.legacyUserProfileCustomizations.stylesheets=true browser.proton.contextmenus.enabled=false

6) Reference: I have tried some suggestions below and they did not work for me.

Good Morning, Group!

I subscribe to the IEEE.ORG newsletter.

If I click on their link, it brings up a blank page in Firefox:

https://spectrum.ieee.org/post-quantum-cryptography-nist?utm_source=techalert&utm_medium=email&utm_campaign=techalert-07-14-22&mkt_tok=NzU2LUdQSC04OTkAAAGFnAJMEXFrlR7vD0yYOspzMUWdvNdvtGqNnHnbEZI2pUuVQelTwBgCQS3pKCdhLl9XSWiE7boikHvLl6N43J65wa4D-JECtQ23ME38QU_rZMG4

That same link renders correctly in Chromium Web Browser (on Linux Mint 20.3)

By truncating the link to https://spectrum.ieee.org/ Firefox brings up that parent page O.K.

This behavior is not confined to this link in particular. It has behaved this way for some weeks (months?) now, in previous newsletters.

This is not an onerous situation but, if it could be fixed, it would be appreciated.

Thanks in advance,

I use the Feedbro-Addon, which creates an own tab. Its url is: moz-extension://285d678c-ecb3-4003-923d-835fc9d8e0bc/reader.html

If I use it as a normal tab (instead of a pinned tab) ... it survives a Firefox restart. But if I use it as a pinned tab (which I want) ... it disappears after a Firefox restart.

I suppose it has to do with it being an addon-page instead of a "normal" page.

Is there a way to make it stay permanently pinned?

I am using Pop OS, which is based off of Ubuntu.

Somehow I did something, and it made the icon disappear for Firefox. I figured I could easily search the internet and find a simple solution.

I temporarily fixed it last night, but here it is missing again.

I could upload a picture, but I don't see what difference that would make. The dock at the bottom has a spot for firefox, but no icon, literally an empty spot, In the application menu it is a blank spot with Firefox worded underneath.

I have uninstalled, reinstalled, purged, deleted the application data in my user folder..

Just annoying. not a huge problem.
