Firefox 技術支援討論區

Hi experts,

I installed the latest firefox 91.2.0esr (64-bit) yesterday on OS centos 7.9, and use the Mojave-light theme. I change the close, maximize, minimize to the left top corner of each window and change such order under dconf-editor. Remember, my order is: close, maximize, minimize, (red, green, yellow), NOT close, minimize, maximize,(red, yellow, green).

Actual results:

The actual result is that: only firefox doesn't take effect. Only firefox window has the WRONG order: close, minimize, maximize. (red, yellow, green)

Expected results:

It should be: close, maximize, minimize (red, green, and yellow)

or:

how to change the order of close, maximize, minimize in the userChrome.css?

PS1: changing to the default theme, or using safe-mode doesn't work.

I get backup from my filrefox such as :

cp -rv ~/.mozilla/firefox/* /mnt/my_external_hdd_mounted/myfirefox/

In new linux I did the following steps:

1. rm -rf .mozilla/firefox/* 2. cp -rv /mnt/my_external_hdd_mounted/myfirefox/* ~/.mozilla/firefox/ 3. chown mohsen.mohsen -R ~/.mozilla/firefox/

By the way, both of them are version 91.

But after run of firefox, I get the error of attached picture.

I noticed the toolbars had changed positions and thought I'd use the customize page to see if I could reorganize them. Somehow I ended up with the usual three toolbars, but bookmarks are on the top (tabs) toolbar, not the bottom (bookmarks) toolbar, which is empty. This is Ubuntu 21, firefox 95.0b2.

Top: Starting on the far left are the Ubuntu window controls, my bookmarks. and tabs. Middle: The customized URL/search bar. Bottom: The bookmarks toolbar, which is empty. I know this is so because CTRL-SHIFT-B hides and shows it.

I can drag bookmarks on the top(tabs) toolbar around, reorganize them, and and delete bookmarks and folders, but always only on the top (tabs) toolbar. I cannot drag any of them to the bottom (empty bookmarks) toolbar.

When typing it comes behind al lot. It happens in input fieds, when typing in the adress bar. I also get lag when scrolling. I have tried all the thinks i can find. I have used troubleshooting mode, disables the addons i use (its just dark reader and uBlock orign). I also dont see a high CPU usage or RAM usage. I have disabled and enabled hardware acceleration, smooth scrolling and autoscrolling. Next to that i have also reinstall firefox. Today i also tried to make an new profile. Still got the same problem. It has not crashed yet so i couldn't find crash logs or something the kind. I have dual boot and on windows and don't have this problem there.

If you need some system information or other information, ill provide.

Hello, I am currently customizing my firefox browser in userChrome. I am currently stuck on one issue. I have an add on that is called "Image Video Block" . I am wondering what code is needed for userchrome to hide the add on when i right click on the screen? Any help would be appreciated. Thanks

Good day, first of all I'd like to appologize because I cant seem to find any dev/support email on the main website mozilla.org so I'd like to request that if possible. This is a long read, partially why I didnt want to discuss this here but alas I have no other choice since contanting anyone from this company was unsuccessful on my part. However, since, as I assume, the devs are hiding for reasons that should be a surprise to nobody, I'd like to point out a few problems that I have encountered with using this browser, or pretty much ANY browser in this day and age.

As you all know, browsers take up a big chunk of memory when loading multiple websites. In fact, I assume that most of you have at least 8G of RAM so you might not notice the things I will be talking about here.

The thing I'd like to talk to someone about, and I really mean someone who might be competent in solving this issue, becouse this isnt only a technical issue, but a user-ignorance-enabled-compliance issue. Recently, I have decided to secure my computer a bit more due to various cyber-threat alerts and whatnot and came across `firejail` which is a neat program to sandbox applications. I then made sure to start firefox through it. Then I went one step futher and decided that the constant swapping from having 4 tabs open and having my computer brought to a screetching halt, was enough of an issue that I finally decided to do something about it. To my surprise, firefox simply, would not start, unless, I gave it at least 2700MB of memory AND 300 (yes 300) subprocesses/forks for it to function. This problem was repated on chromium too, but I wont talk about it since this is the mozilla website. Mind you, I have an old computer with a max of 3,2G of RAM and a humble Core2Duo CPU. 99% of programs do not have any issues with my low specs, except of course, browsers in general. Now before anyone suggest I get a new computer, let me suggest something to you:

How about you learn how to fucking do your job? It isn't enough, that the wave of javascript confused web-monkeys fancy themselves as programmers of the modern age, when they need to pull megabytes upon megabytes of javascript code from 10 different sources for their hello-world grade "enterpreneur" landing pages with 10 different popups to even start considering to work on something (jQuery, React, Vue, whatever-else the f*ck you m*rons use) But we also have to deal with programs, that, for some strange reason, thing they require half, if not all the concievable resources of the machine they run on. No wonder that in todays world, people refer to these programs as malware, bloatware or spyware, depending on what the program is sending about you to servers you have no idea about, but you could get an idea if you just intercept the packets firefox is sending for example.

So, after that little went I will let you meditate on the following fact: When I run firefox with the limit of 3GB and 300 max subprocesses and open facebook, it crashes after a few minutes. LinkedIn Survives a little longer. Now that is a fact, you can test it yourself. Here is the code I use to start firefox:

firejail --rlimit-nproc=300 --nice=5 --cpu=0 --rlimit-as=3000m firefox %u

The `nice` part means to treat firefox with very low priority. This is to prevent my computer from hanging or swapping, by opening a few tabs and facebook or linkedin, and that is not a joke. I am aware that placing it so low on the prio list can cause issues but i did that after I had those issues. So no. I wont change it.

And I dont even comment on the flickering and graphical glitches that occur, simply because firefox doesnt have more than 3Gigs of address space! ITS RIDICULOUS! I wont attach any pictures as of yet, but I might in the future if you really want to see webpages just falling apart in front of you. And I mean it. ghosting characters (screen glitching/duplicating) pictures just randomly disappearing based on your mouse position (yes seriously) and then reappearing just when your cursor is in the sweet spot. Sometimes I have to scroll to find the sweet spot to see the pictures.

Now, mind you, this applies to pretty much any browser. I am just re-iterating this point because I want people who actually read this to be clear that this is more of an issue with the coding habbits people came to be accustomed to.

First question I'd like answered, besides how we got to the absolute clusterf*ck that is the modern web, how does a website, take up 3G+ of RAM? why would I need 8G of RAM just to browse the internet, when roughly 10+ years ago, I only needed 2G and that was enough to browse any website with many tabs and flash-powered videogames to run smoothly PLUS a simple 3D videogame rendering on top of that, on an intel pentium 4 or older? And 2g was considered a lot back then (maybe not exactly but you get my point). I hope I am not the only one noticing this trend. Because this is a very concerning trend. Needless to say about the countless problems people experience these days due to cyber attacks and data breaches and whatnot.

Second question is this: Is it possible, for you people at mozilla, to reduce your applications memory footprint? say, down to a few hundred. If not, I want to know why. And really explain it in detail to me, all the programming aspects of it. Because I honestly do not see any reason why a web-browser, should take up more than 1g, and that is being generous.

Third question: Will you, or anyone, ever care about fast and efficient software? You want to support people in poor countries yet you ship THIS? You want to support developing countries, when your software effectively forces them to invest in expensive machines to even browse the web? Don't kid yourselves, you arent helping anyone. If you were selling 4g i5 cpu laptops to your browser alone, I wouldnt be surprised. Because that is the absolute minimum one has to get to "check their emails" RIDICULOUS!

Fourth question: Did you ever think about how people were developing whole video-games with only a few kilobytes of ram and the games, well, worked? Your browser cant live in a low-budget environment. It wont even start. Or are we planing to send children in africa alien-ware laptops so that they can register an email address? "ooh boy it better have the newest GPU GeForce RTX 3080 TURBO X, 128Gs of RAM and i78000 with 10Thz too so that I can play me some FLASH(Unity WebGL) GAMES"

I am done with my complaint, I will be copy-pasting this to chrome developers too. I know you wont do anything about this, because if it really mattered, you would have done something about it already. And you didnt. And you wont.

Have a wonderful day.

I am using:

• Mozilla Firefox 94.0
• Linux Mint 20.2
• Linux Kernel 5.4.0-90-generic

In Firefox, the issue is with

• Bookmarks > Manage Bookmarks
• Tools > Downloads
• History > Show All History

If I have opened Bookmarks then for some reason minimized the window , or clicked somewhere so the Bookmarks window is in the background , and I again click `Bookmarks > Manage Bookmarks` , nothing happens . My expectation in the Bookmark Window will come on top.

This is true for Download and History window as well.

If I have opened Bookmarks / Download / History then for some reason minimized the window , or clicked somewhere so the Bookmarks / Download / History window is in the background , and I again click `Bookmarks > Manage Bookmarks` or `Tools > Downloads` or `History > Show All History` nothing happens . My expectation in the Menu option I clicked, its Window will come on Top.

Just to be clear I have even tried by clicking `Always on Top` on the Bookmarks / Download / History window.

Why this is not happening?

Help please,

Firefox can't find websites on Ubuntu O/S. Yet when I use Tor browser on Ubuntu, I can surf. Firefox works fine on WIN 10 (Dual boot laptop).

ASUS VIVOBOOK 15 O/S: Ubuntu 20.04.3 LTS and WIN 10 CPU: AMD Ryzen™ 7 Mobile Processors with Radeon™ RX Vega 10 Graphics RAM: 12GB DDR4 - 2400 MHz Firefox: 94

ping tests failed nslookup google.ca failed

PC

This the second time I am entering this problem -- the first time Firefox refused to let me return to this site.

First, I am running Firefox on Ubuntu, but Ubuntu is not relevant because the same issue occurs in Windows.

Whenever I access a file, for example, one at https://species.wikimedia.org/wiki/Chioneosoma, its color (which is programmable) changes from a light bluish green to a deeper violet. Where is this color-difference stored? I have thousands of WikiSpecies files I have accessed, and they all show the violet "accessed" color if I ever have opened the file to read its contents. The problem is that when Ubuntu has to be reinstalled, I can add references to all my files, but the color-changes seem to be lost. This is a serious issue, because I currently have over 50,000 files referenced (and saved in my directory file:///home/jwill/Documents/WikiSpecies/Animalia_Plantae_8) and am still adding to them!

I think the storage location must be somewhere in one or more of the following files ('_' replaced '/'):

   _home_jwill_.mozilla
   _home_jwill_.cache_mozilla_firefox 
   _home_jwill_.cache_MM_firefox
   _usr_lib_firefox

Can you please tell me where the list of accessed files is stored? Whenever I enter a referenced directory, to access it, the color changes; so, Firefox must be able to store a reference to each new referenced directory name.

Hi,

Yesterday Google just disappeared from the available search engines, I did not make any changes to the system as far as I'm aware of. I tried a complete reinstall of firefox (by apt purge and rm -rf ~/.mozilla and then reinstalled using apt) and also followed the instructions in this thread, which did not work for me: [https://support.mozilla.org/bm/questi.../1264497]

Thanks in advance!

Dear Community,

I recently updated Firefox on my Gentoo system (Window Manager is Ratpoison). I had a shortcut <Ratpoison escape key>-F to open firefox. Before the update I used to press this combination again and another FF window comes up without any problems. Thus, I had 5-6 running FF windows on a normal working day, each with several tabs in it.

Since the update, when I use the same method, no new window appears but after a few seconds the message window comes up saying that the running instance is not responding and that FF could not be started. I know the problem with concurrent access of the profile. But, there was (and should be) the functionality that FF connects to a running instance and opens a new window in it. Unfortunately, I do not know how this works programmatically. I already installed dbus (and yes, I also started the dbus daemon) to ensure that this is not the reason - I usually do not use dbus in my setup.

Is there a way to reliably trigger the running instance to open a new window from my window manager? How does this "connection to a running instance" usually works? Why is it not working? What can I do to use it, are there any requirements needed?

Thank you very much for your effort to help me out.

Kind regards - M4tze

fresh install RHEL 8.5 FF 91.2.0esr

i start a vid in youtube. the sound has static. if i open another window, even on a site that doesn't play video or sound, the sound and picture on the first window instantly get out of sync. the picture runs about 2-3 seconds ahead of the audio.

i have not customized the setup. this is a "stock" configuration. i have lots up upload, download speed. 20Mbps up, 80Mbps down.

I know that a extension, ones that add functionality can be installed from a local file on my PC but i need to know how to extract the extension and store it on my home PC ? I know there are scripts available but i don`t remember where.

Every time I play this online game at the site, Wormax.io, it will lag and/or crash the tab after a few minutes of playing. Occasionally, the site will take a very long time to load.

Here's my crash report: bp-4fd287ff-c2e1-4168-8e9d-ac1950211202

I simultaneously open two links of a bookmark folder by using the mouse scroller click. This is a most useful action, but once the pages are opened, they have to be re-selected to be pinned. Is it possible to open them in pinned mode?

Hi, I have an issue with making the separators in the bookmark toolbar drop-downs visible. I am running Firefox 95 with the Quantum - dark Blue theme installed. I am running Linix Mint Uma.

The dropdown have separator - space - but no line showing that there is a separator. I have tried many ways to make the separators visible and with light-grey colouring in the userChrome.css file but nothing changes.

Anybody have any idea what can be done or where I might change the Quantum-DarkBlue coding to incorporate the visible separators?

The documentation says to use F11. F11 was removed from ChromeOS. The Full Screen Button on the keyboard will take Firefox out of full screen, but when you try to use it to put Firefox in Full Screen, the window gets slightly larger, and then goes back to its original size.

Other applications seem to be able to go to full screen using the Full Screen key that are running under Linux. For instance, gvim, thunar, meld, and gnucash all will go into full screen with the Full Screen Key.

Hello! I am using the userChrome.css file to hide the nav bar (# nav-bar) and show it when hovering the tabs.

The following code works a bit, but when I open the developer tools they overlap.

# nav-bar {
   z-index: -1;
}

# navigator-toolbox: hover # nav-bar {
   z-index: 1;
   background-color: rgba (0,0,0,0.8)! important;
}

#browser {
   margin-top: -45px;
}

Any advice to achieve the expected functionality? Thank you

Hello community,

I have tried many fixes I found online to solve this issue but I have had no luck, this issue even persist into troubleshooting mode. Some sites have white text over a white background and other sites like best buy just have broken html/css, this issue just started happening yesterday for no reason as I have not changed anything of firefox since install, the only additions my browser has is bitwarden and nordvpn add-ons. I have attached pictures as examples. Also if it's any help my system is running Manjaro Qonos 21.2.0

Thank you.
