Firefox Support Forum

For some time now, I've been experiencing the following issues with PiP:

• The floating window opens in a random (and annoying) place and does not place itself automatically on the lower right corner as it used to (where I always move it, so it has no memory as it used to)
• It's impossible to keep the "always on top" mode on by default, and I have to do it every single time
• When I toggle windows, the PiP window is always the next one, even when it was not the one I switched from, and I have to always toggle twice for switching between two windows when I have a 3rd PiP window
• When I change language using the keyboard shortcut, it changes the language on the PiP window, and I have to use the language icon bar. Then, the PiP window becomes activated, and I have to toggle back to the window I was working on before (on which I wanted to change language). I have the "separate languages for separate windows" option activated.

It's been some months now, and all those things were working before an update but never came back...

Does anyone know if there's a way of fixing these issues? I've tried things I found online but nothing seems to work.

Many thanks

Noticed yesterday but not as prominent, firefox suddenly steals all window focus, trying to do anything in any other window is pushed into firefox no matter if it is minimised or in another workspace. I have tested this in a clean install along with a clean profile. Bitwarden and other windows seem to act weird when they are interacted with.

This all works well and good on b8 and stable. I am using wayland (Ubuntu 22.* default), but xwayland is available.

I am going through the https://support.mozilla.org/en-US/kb/containers#w_manage-your-containers page and I dont have the option to add new containers when I click on the icon. I am only shown the choice to open the current page into one of the default containers. If I open a new empty tab, this icon doesnt show up in the url bar.

I have gone through the manage extensions options as well and I cant find a similar option. Can anybody point out what I am missing?

Firefox will no longer display the main window. I get an icon in my taskbar but the window is nowhere to be found. I've tried the tricks of maximizing it and moving it but neither works. I have found that if I locate the xulstore.json file it will work but only for a short time. Next time I start Firefox I get an icon but no window. Very frustrating!

The sulstore.json file contains nothing that suspicious:

``` {"chrome://browser/content/browser.xhtml":{"main-window":{"screenX":"2129","screenY":"777","width":"1280","height":"1040","sizemode":"maximized"},"sidebar-box":{"sidebarcommand":"","style":""},"sidebar-title":{"value":""}}} ```

If I start Firefox and right-click the icon, select maximize it's as if it's maximized covering all my windows but yet invisible. I can see my other windows but I cannot interact with them.

Deleting the xulstore.json file often fixes this but it breaks again shortly. What's the deal???

I am running Ubuntu 18.04 and the current version of firefox is 112.0.1. The problem has occurred on two different machines.

My Friday routine normally involves updating my computers. Normally, I start firefox and get some preliminary work things out of the way before using sudo apt-get update/upgrade (sudo apt update) to update my system.

However, firefox has interjected and updated itself twice in the past month or so. When it says it has done the update and needs to be restarted, I click the button and it restarts. This would not be a problem since it was going to get updated anyway, however, when I go to start sudo apt-get upgrade to update the rest of my system, I get the following error:

E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable) E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

This lock traces back to firefox and persists for several hours. The first time I assumed something weird just happened resulting in the lock not being released when firefox restarted after its update. However, since this is the second time that it has happened there is something going on with your updater not releasing properly. Normally, the lock is released immediately after the updating software is finished updating, however, this is not the case with firefox right now.

Please fix this bug.

My FF updated to 110.0.1 (64-bit) on Ubuntu and several things which use to work really well are now broken.

For example, when making a new account, the password manager pops up asking if you want to save the username/password, but if you mouse over to that popup then as soon as you enter it it just disappears. When logging in somewhere, if there are multiple choices for userid (say with different dates) none can be chosen. You mouse down to the popup with the choices and there's a weird stroboscopic action where the popup disappears and is recreated as fast as it can, over and over, and nothing can actually be clicked on. If you type in the userid then try to enter the password the same thing happens. It's not possible to use the password manager anymore, both fields need to be typed in manually.

Another example is the search field. If you type something and there are several options from previous searches, and you try to mouse down to pick one, the popup disappears. If you click the search keyword again it highlights as for replacement, then you have to click it again (removing highlight) and only then can you mouse down and choose a search engine.

etc etc etc! All this stuff worked great until the upgrade happened (in the background) and now many things are a huge pain in the ass. Arrgh!

I tried disabling all add-ons then restarted but made no difference. Password manager is unusable.

These websites won't play audio or video in Firefox 110.0.1, they work in Chrome 110.0.5481.177

https://www.vrt.be/vrtnu/livestream/audio/stubru/ When I click the Play button I get an error "Oops, something went wrong, error code 200" which seems to be a general error code. In Chrome the music starts playing instantly.

https://f1tv.formula1.com/ I have a subscription but video won't play. I can press the Play button, sometimes I see a preloader but the screen stays black, no audio or video. In Chrome the content just starts playing, be it live or recorded content.

Steps I took to get audio/video working inb Firefox, but to no avail:

run above websites in private tabs download Firefox again and run it from its folder in Downloads start Firefox in Troubelshoot mode start Firefox in Troubleshoot mode and Refresh Firefox disabled / enabled Plugin Widevine Content Decryption Module provided by Google Inc disabled / enabled Play DRM-controlled content in Settings disabled / enabled Enhanced Tracking protection disablde / enabled allow media autoplay

In other discussions it was opted to remove the PulseAudio config by running the below command and rebooting rm ~/.config/pulse/*

Any help to get this working again would be greatly appreciated!

Hi all,

Ubuntu 22.04

Yahoo mail can't work properly on Firefox, unable to browse files on computer for attaching it to mail. Attach files -> attach files from computer no response

Please help. Thanks

Remark: Yahoo mail works without problem on Chrome, same PC

I was able to use the media buttons on Ubuntu 22.04, until I re-installed Ubuntu on a new drive.

After the re-install, when playing media on Firefox (like on youtube), the pause button on my keyboard does not work, and GNOME notifications does not show the video that is playing (it used to).

Other apps work fine (such as vlc media player), and I cannot figure out why it suddenly stopped working.

Thanks!

We uploaded vimeo video but video not play and support to some linux sytem browser but this vimeo video play and supprt to window system.

Vimeo video no suppport only linux system

Please see below Screenshot

I'm in Ubuntu 22.04, logged in as user-me. I would like to open /home/user-other/path/to/index.html with firefox.

user-me is in the group user-other, and everything under /home/user-other has permission 755. I can open /home/user-other/path/to/index.html in the terminal without problem.

If I simply type /home/user-other/path/to/index.html in the address bar of firefox, it gives "Access to the file was denied". If I open the file with the file picker, the page is loaded, but as "file:///run/user/1000/doc/some-hax-number/index.html", and the resources in the page are not properly loaded.

How can I properly open /home/user-other/path/to/index.html?

The text for certain parts of the calendar screen are jumbled and impossible to read. I don't have this problem when I open the calendar app using Chrome or Chromium, or in Firefox on my Macbook. It seems to be unique to my Firefox browser on my Ubuntu machine. I am attaching a screen shot that indicates the jumbles I see. The most prominent ones appear on the top line where one can change the week and day one is viewing. There are other places as well which are easily seen on the screen shot, especially when it is "blown up". I don't know how to fix this.

In any case, thanks in advance for your help and consideration. Best wishes, Paul Muhly

When i opened perticular video for playing then video progress bar shows completed before playing the video.How i can fixed that issue in firefox only in the firefox browser i am facing that issue

I use Firefox to download, copy, and store WikiSpecies pictures.

Currently, my .../Documents/WikiSpecies/Animalia_Plantae_8 directory holds what it says are 90,876 items, totalling 11.5 GB. I have plenty of unused space in that directory (over 91 GB), so space is not an issue.

Lately, when I try to install a new picture, I keep getting a warning that the picture is already stored. This MAY be because I am running out of new pictures, but I can't tell.

Is there any capacity limit to a WikiSpecies directory?

Hi, wonderful crew I have this annoying issue: when I want to print a page and I open the Print menu from the "hamburger" button, the preview open but on the printer list I can see only the PDF printer, not my default printer or any other printer.
