Diễn đàn hỗ trợ Firefox

The styles look astonishingly wrong, I really think it is a problem on my end, but cant figure out how to fix it, as you can see in the pictures, text is incorrectly sized and/or justified, color gradients are also weird looking, as well as sizing of many elements and tons of other things.

I have tried to completely remove Firefox from my system and reinstalling it, that did not seem to fix it. The reason I think is is a problem of mine is because i was playing with fonts (emojis weren't working on my system,not on Firefox tho, now they are in both)

I don't think the things i did with the fonts did anything to Firefox, since this problem only showed up on Firefox, but since the problem arrived just after a reboot while I was installing and removing the fonts, I think its important to mention.

To sum up I think the problem comes from my local configuration of Firefox, I probably did not delete it all before reinstalling, I am running (Arch btw) a current version of EndevourOS.

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.

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.

Whenever I use the searchbar in the bookmarks manager, it always searches all of my bookmarks, but sometimes I might only want to search for that query within a specific folder. Is there any way to limit a bookmarks search to only a specific folder rather than the entirety of my bookmarks?

When I open https://www.washingtonpost.com/ it loads but after a few seconds it goes blank. This started a few days ago and only happens on firefox.

I cannot see saved credit cards in Privacy & Security Firefox 99.01.

I moved from a mac to Windows, and sync'd everything. I have no option to see saved credit cards in Firefox Privacy & Security.

Please help?

My images look all glitched out and scrambled. It wasn't like this before, and I don't remember if I changed anything in my about:config.

I've included what they look like.

This bug occurs very randomly, but it seems there have few things in common.

- Occurring on domain level, one domain at once. For example, if Youtube.com stuck, any sub address including each video page is not loaded. Other website and whole browser works fine. - Other program on same PC is not affected, too. - Which page is stop loading is completely random. It might be happen only on a popular, feature-rich site like amazon, google, but not sure. - The timing is also random. Maybe after waking PC up from sleep, but not sure. Frequency of occurrence is once every 1~5 days. - The workaround without restarting browser is 1.)switching to other container tabs(strangely), 2.)opening website on private window. Disabling all the addon manually didn't help.

Since it's randomness, I didn't have any logs about this issue.

Anyone know how to lessen the time that this pointless thing occupies my screen? It's only 4 seconds but sometimes it's in the way. I'd be okay with eliminating altogether too. Thanks in advance.

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. - - - - - -

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 everyone,

Last Saturday, I was able to sign in to Firefox Add-Ons Firefox Add-Ons and submit a pre-release of an add-on I'm working on. But today, I'm being forced to enable 2FA to simply log in to the site. I don't want to enable 2FA, I just don't need it. Can someone explain me why is this happening ? Can I just log in and submit my add-on's update ?

I've tried to sign in two different MacBooks (M1 12.1 and Yosemite 10.10.5), using two different Firefox versions (99.0.1 and 78.15.0esr). Also, I haven't enabled 2FA in my personal account.

Thanks in advance.

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.

A routine update from Firefox version 99 to version 100 caused Firefox to quit loading web pages, including the Settings page. Firefox appears to load normally but will not display any web page. The only thing that works consistently is Help/About Firefox. System: Lenovo E495 (AMD Ryzen 5 3500U) running Windows 10 Pro 21H2, build 19044.1706 Symptoms:

• Version 100 and higher work correctly in trouble-shooting (safe) mode
• Refresh does not resolve the problem
• Manually removing extensions (NoScript and Cookie AutoDelete) does not resolve the problem
• Uninstalling Firefox and existing profiles (all Mozilla folders in AppData/*), then making a clean install of version 100 does not resolve the problem
• Removing version 100 and reinstalling version 99.0.1 restores normal operation (repeatable with higher versions)
• Updating from version 99.0.1 to version 100.0.2 or version 101.0 does not resolve the problem
• I have not tried removing any Mozilla registry keys

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"

Since the Firefox 99 update loading some pages (for example, the Gmail sign-in page) using Firefox on my Linux Mint machine, that I'm running a VNC remote desktop session on, results in a crash.

Crash report ID: bp-5dc1e89d-dc1f-40f2-9dbe-7f4380220419

I've tried running Firefox in safe-mode and the crash doesn't happen, but turning off hardware acceleration, swapping to default themes, removing all extensions, and completely removing Firefox and the .mozilla folder and then re-installing Firefox have not changed the crash behaviour in the absence of the safe-mode flag.

I would appreciate help in identifying what other paths of investigation I can take.

Hi there , I am interested to know if Mozilla support group is aware of the problem Microsoft update KB4474419 causes? I am running widows 7 sp1. I installed the update as you mentioned in your Firefox 100 release notes. After reboot , I got a beep and a black screen - win 7 won't start. I had to find a way to delete the update so I could boot my system back. I asked few of my colleagues that use the same OS and they experienced the exact same problem. Surfing the web , makes it quite clear - this update is faulty and not compatible with win 7 as Microsoft claims. I would like to get a straight answer - can I update my FF99 to FF100 , without the notorious KB4474419 , or , as of FF100 , win7 sp1 is no longer applicable to Firefox ? Thanks. look4

There are a number of old threads regarding this and having worked through them it is still unresolved. 1) I have cleared cache/cookies 2) I have disabled all extensions 3) I have turned off tracking 4) I have tried in safe mode - still the same.

This is not just on one website - it is on ALL that have Facebook feeds. It is NOT just on my laptop - I have asked others to try - they have the same result - blank page. ...so please don't suggest re-installing Firefox!!

An example is: https://dragonsdensoftplay.co.uk/News-Events/news-events.html

The feed works ok in other browsers.

Thank you
