Diễn đàn hỗ trợ Firefox

After upgrading to fedora 40, firefox just takes ages to boot up, even when it's running if I want to open a new window it still takes ages to run. I have tried uninstalling it and deleting it's data but with no luck. The issue still presists.

I am using Firefox v140.0.1 Snap on Kubuntu 25.04, Kernel 6.14. Since the Firefox update in the past couple days, the mouse cursor has started appearing huge and slightly blurry (as though the image is scaled up) in Firefox and nowhere else. The size is visually annoying, and occasionally difficult to know exactly where I'm clicking (trying to move the caret in a text box for example). It also appears to be a different style from the main desktop cursor, the shape and color are ever so slightly different, but this may already have been the case and I simply didn't notice because of the previously small size. Firefox doesn't have its own built in cursor settings that I can find, nor obey the system cursor settings. I have a high DPI display so perhaps it is being over-compensated for? e.g. both the system and Firefox are scaling the cursor up, assuming the other hasn't done it already, resulting in a cursor that's too big.

In Linux Ubuntu I created 4 different launchers for 4 profiles.

Firefox opens the different profiles correctly, but the name of Profile 4 is displayed in the title bar for all windows. This causes confusion when I'm using the different profiles. Furthermore, the icon displayed in the icon bar is also the same for the 4 profiles, although I have configured a different icon for each profile. I ask for help as I need each instance to have its own name and icon displayed correctly.

The launchers look like this:

firefox-profile1.desktop: Name= Profile 1 Exec=firefox -P profile1 --no-remote Icon=~/.local/share/icons/profile1.png

firefox-profile2.desktop Name=Profile 2 Exec=firefox -P profile2 --no-remote Icon=~/.local/share/icons/profile2.png

firefox-profile3.desktop Name=Profile 3 Exec=firefox -P profile3 --no-remote Icon=~/.local/share/icons/profile3.png

firefox-profile4.desktop Name=Profile 4 Exec=firefox -P profile4 --no-remote Icon=~/.local/share/icons/profile4.png

Saying "you can turn off the AI" is NOT enough, Mozilla. Nothing is ever "turned off" unless it's completely removed. This is Microsoft's playbook BS; "but you can turn it off", but for some reason the system is always using a metric ton of memory, lagging and whatnot. You, of all companies, should know this and be better than that. Nothing good is ever force-installed and impossible to remove. Unless you all make it installed completely separately so people like me, who are a significant part, if not most of your user base, can not install it, nothing short of a full renunciation of the CEO will suffice to make we trust you again.

"Internet for People, not profit" is seeming more and more like blatant false advertising every day.

For the last 2 weeks I started having problems with Firefox working consistently. Sometimes only tabs crash, sometimes Firefox crashes. It is not tied to any actions, a tab can crash even if you don't perform any actions in the browser. I have tried clean install on Fedora and Vanilla OS, native and Flatpak packages. The result is always the same - tabs or Firefox crashes every few minutes.

I actively use keywords to search from the address bar, mainly g for google, gs for google scholar and w for wikipedia. Until a recent update (until last week, I think), pressing ctrl + L to go to the address bar would select all the text in the address bar, including the keyword, such that if I had made a google search by typing g and some query, I could immediately do a wikipedia search by typing w and some query.

Now, with an updated firefox (141.0.3, on xubuntu 24.04), the search engine from the previous search remains when I press ctrl + L, so I have to type backspace(s) to remove the search engine keyword, before typing a new keyword.

Is it possible to get the old behaviour back?

As title: after running updates, Firefox consistently crashes when launching.

To give more concrete details:

-Running on Linux, specifically KDE Fedora 42. Firefox was updated to 142 from 141, alongside various other updates. -When launching Firefox from any source (directly, through a link, through the terminal etc.), the only window that appears is the crash reporter. -This issue occurs when launching in safe mode. Removing and reinstalling Firefox, including deleting the entire .mozilla folder in Home at the same time does not resolve the issue. I am unable to test rolling Firefox back to 141. -When attempting to launch from the terminal (safe mode or otherwise), the following is output (personal info redacted):

restorecon: SELinux: Could not get canonical path for /home/[username]/.mozilla/firefox/*/gmp-widevinecdm/* restorecon: No such file or directory.

/usr/include/c++/15/array:210: constexpr std::array<_Tp, _Nm>::value_type& std::array<_Tp, _Nm>::operator[](size_type) [with _Tp = HeaderBarButtonType; long unsigned int _Nm = 3; reference = HeaderBarButtonType&; size_type = long unsigned int]: Assertion '__n < this->size()' failed.

Redirecting call to abort() to mozalloc_abort

[ExceptionHandler generates a minidump etc.]

Gtk-Message: [timestamp]: Failed to load module "appmenu-gtk-module"

(I would note that to the best of my knowledge I had not included a plugin for decoding widevine in my Firefox setup, and certainly the Firefox 141 instance on the device being used to write this post (same OS) does not include it) -The crash files in the .mozilla folder, meanwhile, consistently list a segfault at address 0x0.

Any advice on diagnosing/solving this issue would be greatly appreciated. Let me know if there's any other information that would be helpful.

If it would be more appropriate, I could report this through Mozilla's bugzilla instance, but given the issue seems to be very niche (Fedora's ABRT shows a total of 5 unique affected users in the last few days) I am unsure whether flagging this there would be appropriate.

hello, I've been trying to follow Firefox's official guide in the docs and ready 3rd party articles in order to enable payment method auto-fill in Firefox. however, this section seems to be missing from my settings page.

under Privacy and Security, I cannot find anything to do with saved payment methods or the checkbox to enable payment method auto-fill.

how can I resolve it?

I have never managed to get Firefox Sync to work on my devices, I don't know why. I don't get an error message saying it failed or why it failed. I run Firefox on desktop (Linux) and Android, both always updated to the latest version.

My use case is simple, I just want my mobile Firefox to have all the bookmarks I have on desktop already.

On Android, when I go to my account settings it says "Las synced: never". Clicking the "Sync now" button does absolutely nothing.

On Desktop I go to Settings - Sync, press the Sync button. It appears to work, though no feedback is ever provided.

When I go to about:sync-log, on desktop, finally an error is shown. It seems to attempt to connect to https://sync-765-us-west-2.sync.services.mozilla.com/1.5/207352084/info/collections and fails. Manually going to the URL also fails on both desktop and mobile. Entire log below

Hello,

Moving from an older Ubuntu 18.04 machine where Firefox is limited to version 113 to a newer machine running Mint 22 where the current version is 134.

I know how to transfer the profiles but I could not find any information on compatibility.

Would I need to install other versions before 134 to handle any changes?

Thank you

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?

Firefuxxed was refusing to open new tabs so I shut it down and restarted it (always fixes it) and all my pinned and open tabs were gone with no way to recover them, it took me half an hour to manually restore the pinned ones one by one but not all of them as I cannot remember all of them let alone all the open tabs I had (hours of research gone down the toilet).

There should be a way to backup and restore pinned and open tabs so this doesn't happen, the history option does nothing.

OS: Linux Mint 22 fresh install from a week ago Previous version of Firefuxxed updated after this shamossel.

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.

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

I get this error in my console XPCOMGlueLoad error for file /usr/lib/firefox/libmozgtk.so: libwayland-client.so.0: failed to map segment from shared object Couldn't load XPCOM.

here is the video: https://streamable.com/zffknq the issue is about transparent bar with vertical addons and slowly fullscreen animation, and the fullscreen animation isn't config-able, I already set full-screen-api.transition-duration.enter 0 0 full-screen-api.transition-duration.leave 0 0 in about:config, and disable sidebar or userChrome is not work too. and this is happend about one mouth ago after my nixos update firefox.

i cannot print any web page from Firefox. The print option only offers me the option to save as PDF. Firefox is not detecting either my Brother laser printer or my Epson inkjet printer. if i use the print using system dialogue option fire fox shows a printer screen which has a simple entry of line prntr. If that is selected nothing at all happens. Clearly Firefox cannot detect my printers. If I save the web pages to a PDF file then open that file I can then get the normal system printing options and print the page. But all that does is clutter up my file system with files I will only ever use once. This proves the problem is clearly in Firefox and in its inability to detect system printers. I have tried all the suggestions from the help screens to no avail. Is there any other means of sorting this print problem.

Hi, I just want to ask about the customization option on the new tab's low right corner (the little pencil icon). I've had a background image called "Galaxy" that i thought was pretty, but it disappeared (probably sync settings on other devices, idc) and now the background is just system gray. The issue is that i cannot find the system background in "Themes" nor in the "Customization" (picrel) - there is only "reset to defaults". I really like Firefox and this was pretty cool so I'd like it back. Thanks in advance :)

After latest update 136.0, a TB icon showed up in the 'system tray'. I'd like to hide it, I have no use for it. Browsing the settings including the advanced preferences yields nothing useful.

I am using Firefox in a Linux environment with multiple workstations, where I may be logged into more than one workstation at once. The workstations have an auto-mounted home file system such that my home directory (including my Firefox profile directory) are shared.

Because of this, when I try to launch Firefox on a second workstation, I get an error saying "Firefox is already running but is not responding". I have read the support articles about this issue, and other community support threads, but none of them address this use case.

I wish to use the same profile, so that I still have all my bookmarks and such, and have them continue to stay up-to-date. How can I do so in this environment?
