Diễn đàn hỗ trợ Firefox

Hi Firefoxes! I updated to the latest and greatest 99.0.1, whenever i use the middle mouse button it opens every link in 2 tabs. Also when i middle mouse on a tab, 2 tabs are closed. Anyone came along this bug? Restarting FF and Windows did not help. Trying to get my notebook charged and check it on my macbook.

TYVM! Best regards, -John.

Hello, so I am not very experienced and recently discovered how to customize Fire Fox using the userChrome.css file. I went through all of the steps that are required in order to do this. I set up a folder called chrome in the directory /Users/my name/Library/Application Support/Firefox/Profiles/x1oheo82.default-release To test if it works I wrote this into the userChrome.css file: @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* set default namespace to XUL */

1. TabsToolbar{ background-color: #FF0000 !important }

and set toolkit.legacyUserProfileCustomizations.stylesheets to true After restarting Fire Fox I saw that nothing changed. I double checked if there was a hidden file extension or if I might be in the wrong directory. I tried different code to see if there was some error in the code but nothing changed. I watched countless tutorials on You Tube and tried to find answers on google but nothing that I did seemed to help. I don't know if it has something to do with the operating system I am running or if it is a limitation of my computer hardware (I am running Fire Fox on an m1 mac).

I need to reset my password and I have all my firefox files from "appdata/roaming//monzilla/firefox" but will I be able to restore all my data from it after the reset or will the reset prevent anything? Will it work?

I want to be able to sync my data and know my password for this account.

I am aware that there is a guide for restoring profile data, but I dont know what happens after I reset the password and still try to restore the profile.

I cannot play CNN videos in Firefox. They will not start. I can play them in Microsoft Edge and on my iPhone. I can play other videos in Firefox from, say, YouTube. It's just CNN that seems to be the problem. I have a Windows 10 PC.

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"

Any way to cast to chromecast with firefox?

It's annoying that I have to use Chrome or Edge to cast youtube to my TV.

Or use my phone. But it's charging atm. So very annoying my favorite browser can't do this simple thing. But all the other browsers can.

Hi.

I need to print out my saved passwords. I have no cellphone to access, just my laptop and printer. I only use Firefox and no other browser. If my laptop gets hacked or breaks down, then I need to use someone else's computer to access my passwords in an emergency, and can't access my passwords to do so...so printing them out periodically is the smartest thing I can think of.

Help, anyone? This is pretty important to me. Thank you!

I have fedora 36 Linux on my laptop and I have installed Firefox from the software store. The version in Help>About>About Firefox shows 99.0.1 (64-bit).

I am able to play videos on Youtube but no video or GIF is playing on Twitter/Reddit/Facebook.

I have installed media codecs as per this fedora help

My autoplay setting look like as per the attached image. I do not have any extensions except Bitwarden on Firefox.

I also tried playing videos on Firefox 100 by downloading it directly from firefox website but faced the same issue.

Not sure when it began, probably before the current version, i.e. it's not related to the latest update. When exiting, everything seems fine at first but then Crash Reporter pops up. If I try to restart my Windows/PC with FF open, the restarting becomes blocked by Firefox, so I have to cancel the restart and deal with Crash Reporter first.

The same crash happens in Troubleshoot Mode.

I don't have any special security software (aside from Malwarebytes with real-time protection disabled).

Latest reports: bp-3e00592e-2756-43bf-9642-01b550220502 bp-2435de7c-8279-4d85-b151-b94380220502

Signature is different (almost) every time but as far as I remember no crash felt any different from the two crashes above. For example: bp-093ec6db-d0e2-4f05-8dbd-e03b50220429 bp-47c1b14c-cba2-4007-9f53-089fc0220429 bp-f4ca1090-d760-4209-a47f-8d40e0220429 bp-4a506f38-75ac-4f62-b4bc-324f00220429 bp-d9a19762-4234-450e-82ed-d41940220429 bp-1b0e9da0-29e6-4107-ad7e-ed77f0220429

MacOS Monterey 12.3.1 FF 99.0.1 Have tried clearing Cache, Cookies, Troubleshoot mode.

Google Maps > Search > Share > Embed a Map, the map to be embedded is not displayed (likewise when embed is pasted into Wordpress page, for example)

While same procedure in Safari or Brave works as expected (map to be embedded is displayed in Google maps and embed code displays map in webpage using Brave or Safari).

From the Google Maps page > share > Embed a map > right click This Frame > Open in new tab And then looking in the Console. There are a few other ignored errors but then this...

Loading failed for the <script> with source “https://maps.googleapis.com/maps/api/js?client=google-maps-embed&paint_origin=&libraries=geometry,search&v=3.exp&language=en&region=us&callback=onApiLoad”.

When I try to connect to nespresso.com get a message ACCESS Denied - see below.

I do not have any problem connecting using Chrome or Edge, so this seems to be clearly a Firefox problem.

Hello!

I always use private browsing so I thought that my history was totally not being saved, but discovered recently that when I started to type within the search field, that many of my past searches were listed in the search field with the type highlighted in purple. I had to manually go in and delete all of these past searches. I don't want any search history to be saved. Is there a setting in preferences that I'm somehow missing? Why is Firefox saving these past searches if I have it set to Always Use Private Browsing?

Thank you!

I had been using Firefox browser for awhile, but because of playback performance issue, I have to using another browser just for video playing, especially for 4K video.

Compared to Edge, Firefox seems taking more resources to playback the YouTube video and more heat. When look at the Task Manager, the Video Processing is 0%, and GPU is running significantly more resources on '3D'.

When I start to type a reply to a Facebook post, the page scrolls down so that the line I am typing disappears one line below the bottom of the screen. I have to scroll down to see what I'm typing. Also, it jumps down the same way whenever I hit the backspace key to edit what I'm typing.

I discovered a previous (archived) post on this forum that suggested using "about.config" and making sure that the value setting for browser.backspace_action is equal to 2. But that didn't change the annoying behavior. Is there any other value I should try? It's not clear what the number means.

Nor did setting browser.backspace to true (or to false) seem to help with the unwanted jumping upon use of the backspace key.

This only seems to happen with Facebook, but it's quite annoying.
