Diễn đàn hỗ trợ Firefox

I am trying to sync Firefox data to new computer. The Mozilla account only allows me to sync mobile devices. Online instructions do no match my version of Firefox 131.0.2, Ubuntu 24.04.

I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

Hi! I'm using Firefox 126.0 on Fedora 39.

Pages from Amazon.co.uk load very slowly, incompletely, or not at all. All other Web sites are fine.

I had a couple of certificate-related errors saying that the identity of the site couldn't be verified, but I can't reproduce the problem, so I can't quote the exact wording, I'm afraid.

The same Amazon pages load properly in Chrome on the same machine, and they load properly in Firefox in a VM on the same machine. That tells me network connectivity must be fine.

I've tried disabling all extensions, reverting to the default theme, running in Troubleshoot Mode, clearing cookies and site data, clearing the startup cache, disabling hardware acceleration, and creating a new profile. The new profile helps slightly, in that it loads more of the page before getting stuck. Nothing else helps at all.

I'd prefer not to refresh Firefox if I can avoid it, because I don't want to lose all my plugins and settings. This installation is five years old. Besides, a new profile didn't fix the problem.

What's the next thing to try? I'd really appreciate any ideas.

Hi, I'm using Linux Mint 22, Firefox 129.0 (64-bit). Browser is hanging after approximately 4 hours. Not sure if this is a Firefox issue, but this is where I'm starting the troubleshooting process. My suspects are (1) the browser, (2) NVIDIA drivers (3) the new Linux Mint kernel or possibly (4) a mix of the above. This was a fresh install with default options on (Wilma). Using the latest graphics drivers for GeForceRTX 2060, driver version 555.58.02, went down to native drivers, no change. Honestly, this one has me baffled. Been troubleshooting this for 3 days. It feels like a memory leak. Nothing on the crash reports. First, browser will hang, then mouse and keyboard. Hard reboot is the only option. Any help would be appreciated.

The latest version of Firefox (115) always launches at fullscreen size in linux. I rarely use any application at full screensize because I like to have other windows open on the desktop at the same time. Virtual desktops are not always convenient. I have tried using the -geometry option at the command line, which is usual honoured by applications running under X11, but this is ignored. Nor can I grab the bottom right-hand corner and drag it diagonally to resize it dynamically. Maybe there is a setting somewhere for initial size?

I am using FF 129.0 64 bit on Linux Mint. AFAIK all is up to the latest version.

When I log into my website admin on wordpress, my site gets redirected for a security check on the server (lightspeed or PC Guard). Once this is complete, the login continues.

Unfortunately for the last 6 weeks, my website redirects with a message, "Verifying that you are not a robot" and it hangs there permanently.

I have tried to get my server to disconnest Lightspeed and PC Guard (but then have NO security protection). Nothing seemed to work, and access was sproradic, but seemed best when FF was completely cleaned, cache, cookies, etc. However, even this did not guarantee a login.

Then I found that all worked perfectly using Chrome. Further, having logged in using Chrome, the FF version would now be unlocked and work perfectly.

So it seems as though FF is not clearing a status/flag/file somewhere and that Chrome clears this, leaving FF working again - for another 24 hours. Then the whole cycle starts again.

Any ideas?

This topic appears to show up a few times, but none of the solutions work for me (e.g. they were using A/V or "it just worked"). The error I get is also different.

This a pretty fresh install (migrating from Chrome so I'm currently re-logging into all my sites to ensure I can access everything I need.. and going through MFA hell heheheheh).

Everything is mostly fine, except for Synchrony Bank.

I go to login at https://auth.synchronybank.com/account/login, enter _any_ username or password (doesn't matter if I enter the right details or the wrong ones), and as soon as I click "sign in" I get an error page

Looking in developer console, the error reason given is NS_ERROR_NET_INTERRUPT while trying to POST to auth.synchronybank.com. Every so often I get PR_IO_TIMEOUT_ERROR but over 90% of the time it's NET_INTERRUPT.

This occurs also in private browsing and also in safe mode. I even created a new profile and tested it from there; same issue.

I've tried lots of things related to this (e.g. setting network.http.http3.enable to false), added the domain to the advanced tracking exception list, and I'm running out of ideas.

I can see traffic flowing to akamai but (it being https) I can't see what's inside the traffic. Could akamai be objecting to something in the content?

FWIW, I can login with Chrome on the same machine.

I need to connect to my employers Citrix portal tot start a Citrix session for my daily job. The problem is that when try to login using my credentials nothing happens except for the loading icon of Firefox that keeps "spinning" (see image).

When I do the same in another browser, like Chromium for example, everything works fine.

I already tried the following steps:

- Installing an older version of the Citrix Workspace app - Reinstalling Firefox - Disabling the blocking extensions

I am using the following versions of components:

OS: Linux Mint Vanessa 21 Citrix Workspace app: 24.5.0.76 Firefox: 129.0

Other colleagues report the same issues when using Firefox whether in Windows of Linux.

Any help would be much appreciated?

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

Hi. I was just looking at Google Photos on both Firefox and Chrome. Chrome had a bigger picture because the window had only the tabs bar and the address bar, and Firefox has an additional title bar. I was wondering if it would be possible to remove the title bar so the picture on both browsers were the same size?

This issue is happening with every newly installed add-on, but not with add-ons installed on or before Aug 3, 2024. The add-ons are installed via addons.mozilla.org. To rule out the possibility that it's happening only with specific add-ons, I also installed one of the random recommendations on that page, Augmented Steam which has 54,248 users, and it happens with that one as well.

I'll click Enable, but the prompt appears every time I restart Firefox.

What I've tried (with a restart after each attempt):

• Clear the startup cache
• Delete extensions.json
• Delete compatibility.ini
• Via about:config deleted extensions.databaseSchema and extensions.getAddons.databaseSchema
• Excluded Add-ons from syncing

I've noticed the following in extensions.json for each of the recent add-ons after restart:

• syncGUID changes to presumably random new value
• active changes from true to false
• userDisabled changes from false to true
• seen changes from true to false

Twitch, Youtube Live, Netflix, Kick... it seems any live streaming platform cannot play. I am running Linux Mint 21.3, Kernel 5.15.0. They work on a different browsers, they all also work on Firefox my laptop, which is also on the same OS and Kernel.

I have tried everything: installed ffmpeg, installed unrestricted ubuntu codecs, refreshed firefox (twice), uninstalled/reinstalled firefox, ive tried without extensions, yet nothing.

Cant for the life of me figure it out, im not sure if its my PC or Firefox on this machine.

Sync is a nightmare. It is so unintuitive! What exactly would be wrong with having separate Export and Import buttons for each of Settings, Addons, Tabs, History, Bookmarks, etc? I have a desktop box and a newer laptop I wanted to get up to date. I pressed the Sync button on the desktop ... By the way, there`s a link below that reads "Connect another device" ... Connect where? Someone is designing these interfaces who has absolutely zero imagination. Anyways, I signed off, moved the ethernet cable to my laptop, signed in, pressed Sync, and voila!, I got my Bookmarks, at least. But I have no idea how to get my tabs and windows. I tried with a "download link" something or other, but it seemed to assume I was sync-ing to a phone, and didn`t work. Any way to get my tabs?

Any advice returned by Google seems to be obsolete or only worked perhaps in older versions of Firefox. The main idea of using userChrome.css to override the default styles for Reader View does not seem to work. My userChrome.css file does work on other items though (like removing the sidebar width restriction).

Whatever advice I find via Google perhaps cites outdated CSS selectors, but current selectors do not seem to be documented anywhere by Mozilla. Moreover, I cannot find any file on my local drive named aboutReader.css when using find or grep commands in bash, those this file name is alluded to when viewing a page in Reader View and then in turn viewing source on that transformed page.

Moreover, addons that would allow me to change the colors seem to be restricted in Reader View.

It does seem like something has changed in recent Firefox updates but I can't remember when I last saw, for instance, links in dark mode Reader View that were still pink (whereas now they are blue, and impossibly dark to see, especially when you are disabling as much blue light as possible through your operating system). I need a higher contrast color for links in dark mode Reader View so I can actually see them.

I can alternatively use the Tranquility Reader addon and have custom colors, but A) that addon does not work with the Automatic Reader View addon, whereby I can always have various sites appear in some sort of "reader view" whether the native one or Tranquility Reader, and B) hitting refresh when in Reader View will defeat some soft paywalls but this does not work with, e.g., Tranquility Reader, so I still would prefer to be able to custom colors in the native Reader View feature, rather than rely on an addon.

1. Where are the current styles for Reader View even documented? 2. Is overriding them now restricted? 3. Why did the link color change from pink to blue in newer versions of Firefox (this is a terrible accessibility bug)? 4 .Where is the alluded to aboutReader.css stylesheet actually stored on my computer (it doesn't seem to be a file on the filesystem in the Firefox profiles folder, it seems more like it is embedded in the Firefox binary/executable)? 5. Will Firefox settings ever allow us to set colors specifically for Reader View (I don't mean the override settings for all web pages, particularly web pages not being rendered in Reader View ... that setting does not help in Reader View, nor would it be the desired preference for pages not in Reader View)?

Thank you.

I created a few virtual hosts and sites on my local machine and this is working perfectly.

Problem is with Firefox, when I enter non-existant url in address bar, Firefox force me to search and don't let me to open the url, but I need to go to this url for testing, developing, etc...

Any solution?

Hello,

I'm experiencing an issue with the search bar on the Firefox homepage. When I click into the search field and begin typing, the cursor jumps to the address bar, and the text I’m entering gets redirected there instead of staying in the search bar.

I've checked my search settings, and everything seems to be in order. I’ve also tried disabling add-ons, but the issue persists. Could you please assist me in resolving this problem?

Thank you for your help.

Best regards, Tivadar Tot

Firefox 129.0.2 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

Running on kubuntu Linux 24.04, kernel version 6.8.0-41-generic (64-bit) KDE Plasma Version 5.27.11 Qt Version 5.15.13

I've posted a description of my problem on the kubuntu forums: https://www.kubuntuforums.net/forum/newbie-support/help-the-new-guy/681835-firefox-eating-up-a-lot-of-cpu

Here is a synopsis of my posts on that thread to distill the most noteworthy symptoms:

I have snap Firefox installed.

$ snap list Name Version Rev Tracking Publisher Notes bare 1.0 5 latest/stable canonical✓ base core22 20240731 1564 latest/stable canonical✓ base firefox 129.0.2-1 4793 latest/stable mozilla✓ - firmware-updater 0+git.5007558 127 latest/stable/… canonical✓ - gnome-42-2204 0+git.510a601 176 latest/stable/… canonical✓ - gtk-common-themes 0.1-81-g442e511 1535 latest/stable/… canonical✓ - snapd 2.63 21759 latest/stable canonical✓ snapd thunderbird 128.1.0esr-1 507 latest/stable/… canonical✓ - $

If I start firefox from the shell command line, it runs fine. It runs the shell script in /usr/bin/firefox, which ultimately executes /snap/bin/firefox. Clearly that shell script is doing some configuration that I don't understand.

If I​ hit Alt-space I see the menu in the referenced screen grab (see attached).

If I select the first entry, to run firefox from the command line, it has the same effect as starting /usr/bin/firefox from a bash shell; it works fine. However, if I select the third entry, firefox does not play any video; I've mostly tested with YouTube videos that have actual video and audio.

I'm not sure what gets executed when I select the third option from the Alt-space menu. It appears from doing a "ps -ef" that it's the same /snap/firefox/... executable. But I'm wondering why is this entry in the Alt-space menu and how does it get initialized or 'configured' to run.

Additionally, if I do start firefox from the entry with the firefox browser icon, and it fails to play video, I must then uninstall firefox using snap and then reinstall in order to get video playback to work. That is, after a failed start, simply exiting firefox and restarting it from the shell command line will not work; firefox will not play video correctly at all.

I also noticed that on my PC desktop, "snap list" lists firefox as "firefox 129.0.2-1 4793 latest/stable mozilla✓ -"

But on my old Lenova laptop running the same kubuntu version, "snap list" lists firefox as "firefox 129.0.2-1 4757 latest/stable mozilla✓ -"

​I'm up to date on both systems via "sudo apt update"' and "sudo apt upgrade"

Even more frustrating, today, for the first time, despite starting firefox from the command line, video still didn't play. I had to uninstall firefox and reinstall it.

I want to navigate on search results using the keyboard. I could use tab but it suggests all interactive elements such as news, images, books, videos, search settings and etc one by one. I want to press something and make active first result, then second. If such hotkeys are not provided, maybe there are any extensions with similar functionality?

I recently explored the backgrounds on Firefox. I choose one of the, because they look really nice. But after I changed my Firefox Data Collection and Use settings the background disappeared.

Why do you have to keep "Allow Firefox to send technical and interaction data to Mozilla" and "Allow Firefox to install and run studies" enabled?
