Firefox Support Forum

Starting Friday April 19, I have been experiencing constant very brief internet outages/reconnections while using Facebook on the desktop. The outages do not occur anywhere else on the internet...and do not occur on other browsers. I prefer to use Firefox. I am using Windows 11.

this was asked before by myself

/questions/1284841

and again by another user

/questions/1402855

the code was

1. navigator-toolbox {

 max-height: 0;
 overflow: hidden;
 transition: ease all 3s;

}

1. main-window:hover #navigator-toolbox {

 max-height: 100vh;
 animation: 0s pop-in;
 animation-fill-mode: both;
 animation-delay: 2s;

}

@keyframes pop-in {

 from {overflow: hidden}
 to {overflow: unset}

}

the issue now i have with firefox 124.0.2 is that the transition is now instant when my mouse enters or leaves the window and one of my addon buttons (roboform) no longer works with this userchrome.css edit.

its been a few updates ago it broke maybe 15 or so and now im wondering if there is a better updated script that works like it used to.

Hello,

Recently I noticed that whenever I try to save a bookmark (and I save a lot of bookmarks) there are duplicates of my folders. I don't know why, but somehow at some point all my bookmarks got copied into other folders - Bookmarks Menu, Bookmarks Toolbar, and maybe something else. What's frustrating is that one of the folders is the one I use for convenience to access sites I regularly use, while saving to the other puts it somewhere I can't easily get to (I think it's the copies from Bookmarks Menu), so I have to make sure I'm putting it in the right folder - which is hard to do when they have the exact same name. Something I've found that works is to just find out which folder is the one that is in my toolbar and save it to those which pushes the ones in the Bookmarks Menu out of the quick access list, but that's not always convenient given how many bookmarks are in some folders. Using the bookmarks dupes extension, you can see just how many duplicates there are. I've also attached what I see when I save a bookmark, so you can see the duplicate folders.

https://support.mozilla.org/en-US/questions/1444740#answer-1647784

Dear Firefox team.

My Laptop OS was dead, I unable to syncing my bookmark on new windows-10 OS and logging with gmail account.

how can i get the syncing bookmark on my laptop.

can anyone help me. my bookmark is very important and up to date till last week.

Version : 24.0.2 (64-bit https://prnt.sc/jY-u_50dt2b7

I have uninstalled and reinstalled firefox and restarted my computer but it still will not load. When i first reinstall it it comes up but will not connect to the intenet.

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

Mac OS 14.4.1

Firefox crashed and now will not open without crashing. I have trashed it and re-installed but still getting this error and cannot use the application. It will not open in Trouble Shoot mode. I even removed all files in the Library/Application Support

This is the problem report it shows:

The latest version of firefox for MacOS 14.4.1 has broken the picture in picture function. When enabling PiP, the video window takes up almost the entire screen and doesn't remember the size i set it to, like it did in older versions of Firefox. Another issue is when im in fullscreen mode and enable PiP, the PiP window takes me to another 'desktop', whereas before it would simply overlay on top of my screen.

Nothing happens when I press the play, like, dislike, notifications, favorite, or join server buttons. On top of this, when I try to open the catalogue it's just a grey screen with nothing in it. In the attached GIF I am clicking rapidly. I don't believe this is an issue with roblox itself, as when I open chrome everything works perfectly. The only extensions I am using for the site are RoPro and BTRoblox. I have tried to turn the extensions off and have even uninstalled them, however the problem was still not fixed.

When I have the Firefox browser open, every time I click away from it to another open window I get this stupid graphic that pops up near the bottom right corner of my screen that says "Intelligent Work" and rotates through three different images. It is really irritating and I can't figure out how to make it go away. This is a new computer and I only installed the Firefox browser this week. It only happens when I click off of the browser to any other window.

Jag använder ovpn satt 10 timmar igår med att lösa ett dns läckage men det fungerar inte ovpn säger att det är ni på firefox som kan lösa detta och inte de. Jag vill gärna få hjälp via teamviewer. Mvh Carl Sverige

Firefox Version: 124.0.2 (64 bit) Windows Version: Windows 10 LTSC 2019 (Version 1809)

When I right click the taskbar and press close Firefox, here comes the interface just as the screenshot uploaded. The blue close button doesn't response no matter how I click it and the Firefox's taskbar is flashing yellow. This bug only occurs on the first window of Firefox and only when user right click the taskbar.

It has been a long time for me wishing that some updates would be released soon to fix this issue, while noting happens. Or this bug is only for me?

Hello. I use youtube website as music player quite often (without premium) and play my favorite list of songs. Meantime, when Google started meddling with youtube due to their new offer as youtube premium I met two most annoying issues like "are You still watching" dialog and the behaviour where youtube just cleared "repeat list" function without my consent. Both issues was resolved with java scriplets I took from community.

Now I run into third issue but not sure how to diagnose it. If Firefox is in the background, or tab with youtube has no focus the playlists stops from time to time. The moment it stops is when next video should start playing. When browsing on different tab, I can see on Youtube tab that title of the video has changed (to the next video) and even the song started (for 1-2 seconds) then video pauses and word "playing" disappears from tab (normally there should be title on tab and "playing" word under title). It is not "are You still watching" dialog issue because if I move mouse cursor on youtube tab (even without setting focus on it) the player will continue - till next song.

The issue doesn't appear if youtube tab is active. I can't use developer tools in firefox because can't debugging website when tab of the site is not active (at least I don't know how). I tried to find solution with community but with no success. I allowed youtube to play video and sound always without exception in firefox preferences but it is not the solution.

Any tips?

In the Firefox settings, it says "Account disconnected" so I click the sign in button, it opens the Mozilla website, and I successfully sign into my account online. Yet the browser still says disconnected. I've tried a few times. How do I fix this?
