Diễn đàn hỗ trợ Firefox

I was watching anime today on some site and my firefox was downloading many files without my knowledge into my download folder. I'm worried that it can be some viruses? This is a screenshoot. Should i be worried? Thank you for help.

The latest example is the button to sign into LinkedIn. It is not working in Firefox, but it does in other browsers. I have other examples just from today. I have used firefox as default for many years. I assume this is a security thing, but these are basic links. I have no add-ons or other complications. Most times, I do not even realize there is a problem, but when I feel something is wrong, I try another browser and it works. Thank you.

Hello,

I noticed that a setting on the about:config page was removed: the "security.csp.enable" setting. I was using this setting to disable CSP to be able to load local JS scripts on some non-locally hosted sites, for debugging and development, work related purposes.

Was this setting really removed? Is there a way to disable CSP on Firefox on the latest version?

Thanks! Gabriel.

So for starters I am fully aware of the "When you open a link, image or media in a new tab, switch to it immediately" setting, it is turned off.

What I want to do is be able to open new tabs from my bookmarks bar without immediately switching to them. Regardless of middle mouse click or right click and open new tab. Considering the mentioned setting is turned off I would assume that would solve the problem but it hasn't. It has however made it so when I'm browsing or looking through search engine results it doesn't open a new tab right away. But when I have a home/new tab open and am opening tabs from my bookmarks bar, it unfortunately switches to the new tab immediately. I have had this working on a previous install but am stumped as how to replicate.

Any help appreciated, thank you!

my pc had friend so when i got a new one i lost all of my firefox data, how can i get all of it back so i was forced to start all over, i lost all my, bookmarks, tabs, history and saved passwords

I'm running Firefox 99.0.1 on Ubuntu 22.04. Recently (I think since I updated to Ubuntu 22.04 about a week ago), Firefox has been refusing to show me file upload dialogs. When I click a button that's supposed to give me one, nothing happens.

This has been happening with: - The "attach files" button in Gmail - A file upload button on Gradescope (website for managing homework assignments) - File -> Open File... and Ctrl+O.

Dragging and dropping a file onto an email in Gmail does attach the file -- it's just that the button doesn't work.

I've tried restarting, and I've tried running Firefox in Troubleshoot Mode -- so far nothing has fixed the problem. What else should I do?

The credit card autofill shows all the credit cards but when I click on any of them it does not autofill. Ive used this hundreds of times before and it worked fine. I never changed any settings and the autofill setting is on.

Please help!

This sounds like it's a Meetup problem, and in fact it may be, but now I am having doubts.

The problem is that I can't upload photos to a Meetup event. (This will mostly just be a problem for Meetup organizers.) When I click on "Save photo", nothing happens. No error message, nothing. It's as if the "Save Photo" button has been disabled. Firefox is my browser while I access Meetup.com, and I have the latest and greatest version of Firefox.

I contacted Meetup and they haven't been able to solve the problem; they suggested that I clear my cache and my cookies and try again, but I get the same result. HOWEVER, when I go into Microsoft Edge, I can upload photos with no problem. So I have a work-around: use Microsoft Edge to upload photos. So my question to you centers around: why does this work perfectly in Microsoft Edge, but it doesn't in the latest version of Firefox?

To test the possibility that it's a bug on my personal desktop computer, I went to the public library and tried the same experiment, with the same result. So I don't think it's problem with my personal desktop computer.

One other piece of information: the exact same thing happens (failure to update photo, that is) when I have the photo open in another application (Photoshop), even if I try to "save photo" to Meetup in Microsoft Edge. Then when I close the other application (Photoshop in this case), Microsoft Edge lets me "save photo."

I know that Firefox really doesn't want me to try to revert to a previous version, and it makes me nervous too, but I am suspecting that something in the latest Firefox version actually introduced a problem. (Or maybe triggered a Meetup bug of some sort; I still haven't located the problem.) I've been on Meetup.com for years, I've had Firefox for years, they've worked together to upload photos in the past for years.

If you want to get into the details, below, for what it is worth, is my initial question to the Meetup support people (with whom I am still in a conversation).

- - - - - - - -

I can't upload a photo for my event. In fact, I cannot upload a photo for any event at all. I deleted a couple of photos and an album because maybe our group had too many, but that didn't work. I can't even upload a photo that I had previously uploaded to a different event, so I don't think that the problem is with the photo itself.

Here's what happens. 1. Edit the draft of my meetup. 2. Click on "upload photo." The photo is 1827 x 1009 pixels, total size 63 KB. 3. I click on "Upload photo", then in "add photo" I click on "upload photo" again. I browse for the photo and select it. 4. The "crop your photo" screen appears, with the selected photo in it. It's already the size I want, so I click on "Save Photo".(Cropping doesn't help either.) 5. Nothing happens. No error message, nothing. The only think I can click on is "cancel," which takes me out to the previous screen. - - - - - -

on my Win10 64b system the FF browser keeps the tabs visible after the last 99.0.1 update. i didn't make any changes to the browser after that update that i can recall. thx!

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, 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).

An error occurred during a connection to www.facebook.com. SSL_ERROR_DC_EXPIRED What in the world? does Facebook not keep up with its own security? or is this a Firefox thing?

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.

Hello. Since I use the bookmark bar and fullscreen mode a lot, I would like to be able to see the bookmark bar in fullscreen, not on every tab, but only in a new (empty) tab, so that I can avoid disabling fullscreen to access the bookmark bar and at the same time not having any part of the interface visible unless I'm in a new tab. Thanks in advance for any reply!

The instructions for the Window Titler icon suggest to turn on the Title Bar (with the Firefox icon, usually shows title of active tab, but would presumably show the Window Title if one was assigned). I can't find how to turn it on in version 99.0.1. It's not where the instructions for Window Titler said to look (managing the Menu bar or the Bookmarks bar). Any suggestions?

Would love for this feature (named windows) to become a normal part of Firefox. I wouldn't mind having the Title Bar anyway; at the cost of a few pixels, I would have something to grab onto when moving windows around that wouldn't accidentally do something to a tab.

When I load Amazon.com, the webpage is a lot of text and random pictures. Amazon's layout is broken. I loaded the same page in Chrome and Safari without a problem. I reinstalled Firefox 99.0.1 without any improvement. Please fix.

Hello,

I have had a few websites not work properly with Firefox and have needed to open my backup browser (Avast Secure Browser) to use those websites.

Right now it is FedEx that comes to mind again as I kept checking for tracking of packages shipped to me since receiving the tracking info. I queries consistently returned the error message "Unfortunately we are unable to retrieve your tracking results at this time. Please try again later."

Thinking maybe the website was having issues or maintenance (and forgetting I had the same issue with FedEx website the last time I tried tracking there in Firefox), I kept "trying again later".

Then I opened my Avast browser and pasted the same url there and, sure enough, received this report on the display:

Travel History Date or Time City & State Status Monday, April 18, 2022 9:47 PM SPARROWS POINT, MD Departed FedEx location Sunday, April 17, 2022 1:49 PM Shipment information sent to FedEx

I have tried disabling the extension NoScript as well as turning off the "Enhanced tracking protection" and allowing permissions for the FedEx site with no improvement.

I copied and pasted the RAW data as well as the text version from the "about:support" page to send you.

Any suggestions to fix this?

Thank you, Keith McNabb

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 tried this several times over a few years, and have never got it to work I know it must be something I am doing wrong because if it was a glitch or bug, it would have been fixed by now. Usually I need to do this if I need to reinstall the OS, (Windows and Linux), or a new pc, the usual, but this time I had a major crash, so I'm starting over.

Anyway I have signed in on my pc to my FF account, and went through the menu to turn on sync, and I get to the page where is says, "when ready click next to display the QR code". I get my android out, open FF, sign in, click the "Scan" button, the FF scanner opens,, I open the QR code on the pc, (I have also went to the website to get a QR code). Then either way I scan the code, and get an errror msg "Must scan from inside FF". I am scanning from inside FF, with the FF QR scanner.

I don't uinderstand how of the 20 or more times I have tried to do this, I can't get it to work. I don't understand how I screw up every times, over a few years. But I also know as I said, if it was a bug MOzilla would have fixed it by now. Usually I give up on that and just log into both the pc and the phone, close both browsers and reopen them and it will go ahead and sync.

But not this time, I am unable to get it to sync for anything. I've been working on this for 3 days now, and at this point I'm confused, I don't remember what I have and have not done. Let me add, and I don't know if this will make a difference, I don't think so, but what do I know? Originally this all started, when I had to reset my password. I tried for 4 days there to get a recovery code to work. (The following is just to describe what I've done, and is not a second question) I had one downloaded, and saved on my pc. But no matter what route I took to go through the reset process, exactly as described in the help file, I never could get a place to enter the code. I read every article I could about it, and finally it seemed easier to just reset the password and resync than try to get the code to work.

Which is why I am sitting here, desperatly needing to sync my data, but unable to. If anyone can tell me what I need to do I will appreciate it. If you need any more information, just let me know.

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.
