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 have two windows of Firefox 94 for Linux next to each other, each with its own user profile. It would be very handy if I could drag and drop tabs and items in the bookmarks toolbar from one profile into the other. Apparently this does not work out for me. Am I missing some tip/trick?

It is possible to transfer tabs by drag and drop when both windows belong to the same user. Handy. Obviously the two windows share the same bookmarks toolbar, so the point of transferring makes no sense for the bookmark toolbar.

If that cross-profile transfer is not possible, it is definitely a feature request. This would help greatly in merging piecemeal the bookmarks of two users. Say, to separate private and work bookmarks from time to time.

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

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.

In Ubuntu 18.04, I bring up a new page, click in the search bar in the middle of the page. Then when I start typing it jumps to the address bar although I have already placed and preferred the search bar to the right. No! NO! NO!

I use Duck Duck Go but Google does the same.

It is bad enough that the upgrade was automatically loaded but on top of that, changing preferences including dumping my home page. Change privacy settings without asking ( to a lower level on top of that ).

Really POOR form.

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!

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).

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.

When I'm using my Firefox for too long or few couple of minutes its suddenly fronzen and stops response. So I need to restart it, killing the process using top,htop or kill commands. It has been weeks that this problem started. I waited for updates and tried reinstall it, but no futher SO updates and reinstall solved the problem, if the new Firefox release updates could put a end to this problem.

I have here some ID number of my bug report that I send to Mozilla, if someone could help understand if its a package/driver or miss configuration I would like to know.

When press the upper right button 'x' to close, it says that my Firefox isn't respond due to: 'Firefox: Exiting due to channel error'

I don't know how to fix it or find better logs messages to discover what is happens on the Firefox. I have SO with Windows 10 and I don't have this problem at all.

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

I want to change my email to [email-removed], but in order to do that I need to verify I own a secondary account that has unfortunately been shut down Below is a screenshot of my Primary Gmail account as proof I own it, and would again like to deactivate my secondary email entirely, and change my primary. Thanks - Isaac

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 have two laptops, an old one with a synced firefox, and a new one where I want to get all the passwords, tabs, theme, settings and extensions. The OS is the same (NixOS, Linux).

I can successfully log-in and enable sync on the new laptop: it's possible for me to see the list of tabs from the other device, open and sync those tabs, but other things are not synced or synced partially.

For example: of the 30+ passwords on the old device, only 15 are present in the new device; no theme or extension is synced, bookmarks seems to be properly synced.

I don't know where to get more info about the sync (besides the about:sync-log page, which shows no logs), so I can't really tell what's going on. Indeed, nothing changes if I press the "Sync now" button.

I also tried refreshing firefox or creating a new profile from scratch and sync that again, but to no avail. Do you have any suggestion? Thanks

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.

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.

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'm using - System: Kernel: 5.4.0-89-generic x86_64 bits: 64 compiler: gcc v: 9.3.0 Desktop: Cinnamon 5.0.6

In Linux Mint System Settings Firefox is the default web browser. That is also confirmed on the command line. Firefox is version 94.0 for Linux.

In Firefox/Settings/General/Startup - "Firefox is not your default browser" is always bold. When I click "Make Default" it just checks "Always check if Firefox is your default browser". If I leave that checked and close and open Firefox the warning that Firefox is not the default always appears. This is causing issues opening links from other software. How do I get Firefox to retain default status? Linux Mint thinks it is the default already.
