Every time I open Firefox after closing it, I get the message below. I can click the button to restore session and it works every time. With each update, I hope to never see this message again, but after installing a new version on Ubuntu today, I see the same familiar message. This is not linked to a computer, or an operating system because I've seen this on both Ubuntu and Mac. If Firefox could literally just click the button that would be awesome.

Sorry. We’re having trouble getting your pages back.

Hello,

I have a problem with Firefox on Linux, doesn't seem to be distro specific as I've tried Manjaro/Ubuntu/Neon, when using KDE in that when listening to music on YouTube music my computer will go to sleep after the elected time. On KDE you can see which applications are preventing sleep and/or screen lock, other applications are listed here but not Firefox.

When playing a video everything works as expected.

I would investigate myself, but I don't know where to start so if someone can point me in the right direction or offer any insights?

Currently using: KDE Neon KDE 6.0 Kernel 6.5.0-21 Wayland

Hi, I made a theme but have since not used it and swapped to another. Everytime I open the browser, it swaps back to the one I made for some reason. Under themes, it will still say the one that is showing is the chosen theme, but it most certainly is the one I made. I turn on another theme and toggle back to the chosen theme and it then changes correctly. Any idea why that could be?

After an update of ubuntu 22 on my computer, Firefox does not render properly (see the screenshot of my desktop). I have tried to reinstall it but it continues to happen. All the other programs works fine, it is only firefox.

My system is: Ubuntu 22.04.2 LTS Processor: AMD Rysen 5 3600 6 core procesor x 12 Graphics: AMD Radeon rx 5500 tx

Thanks.

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.

Is there any way (or any addon) that I can insert commonly used text into a text box? I have tried AutoFill and, while it works fine for... well.. filling out forms... I cannot get it to work for what I need. Basically, I want to insert things like '¯\_(ツ)_/¯' rather than having to go to a page, select that, copy it, go back and paste it... or, worse yet ... remember and type that over and over again.

So I was sent a picture in .heic format. Trying to open it FF entered an endless loop opening new tabs with names like: "/tmp/pid-949/IMG_9409.heic". There was no easy way to stop it, the 'X' button did nothing. It opened hundreds of tabs. I had to kill all my tabs to get rid of them. BTW there's supposed to be a 'Recover Previous Session' button in the main menu. Not there. On line, I see several different images of what my main menu is supposed to look like but mine is nothing like that. I have 115.6.0esr (64-bit).

I've been having an issue for a while now where the cloudflare challenges that ask you to click the check mark to "verify your connection is secure" would just endlessly ask me to click the button and never continue. Sometimes it would say to unblock access to challenges.cloudflare.com.

But if I a launch an incognito window I can visit website with the challenge and it won't even ask! I've added all my extensions to run in incognito mode and everything still works, I can visit the websites in incognito just fine. So the one changing variable is incognito vs non-incognito.

I can have two windows open, one incognito and one not, and browse to the same website and the non-incog window will fail but the incog will just go to the site.

I thought incognito was supposed to only affect the session storage? Does it silently change other things to the running environment of the browser (about:config options, slightly different extension configs)?

Anyone know why this small change would suddenly allow cloudflare challenges to work?

Hi,

Is there any reason firefox would flag an mp4 file legitimately?

• The file extension and file type are absolutely mp4.
• There seem to be no mp4 related zero days.

Does Firefox perhaps just treat all downloads from suspicious domains as malware? Is there a zero day I missed? Is this based on some missing metadata on the file or something?

Thanks for any advice you can give here, I'm scared.

I discovered two issues with Firefox on my Wayland Gnome. Picture-in-picture windows should be opened with the "always on top" attribute, but in Wayland they are not on top. It's not a big deal to manually set always-on-top. Although I need to remember to do this after the window appears. The second problem is related to selecting multiple tabs. I should be able to detach selected tabs from the window by dragging them from the tab bar. A new window is then created with the selected tabs. This doesn't work in my Wayland. I can detach one tab, but not multiple tabs at once. I can still move multiple tabs from one window to another open window. So, as a workaround, on Wayland I need to open a new window and then move the selected tabs there. Which is inconvenient. I am curious if anyone else noticed these things on Wayland. There might be something wrong with my instance of Wayland.

Hello, in past versions of Firefox, I was able to follow the steps on this page to set a custom HTML file on my PC as my home page for new tabs: https://peterries.net/blog/firefox-ubuntu-local-file/

I have Firefox 107.0.1 now and it's not happening. When I open the browser from scratch, I see my custom home page file. But when I open a new tab, I just see a blank screen. If I then click the Home icon on the toolbar, I do see my custom HTML page, but I don't want to have to click that button for each new tab.

Right now, in my settings, I have the URL to the page set as the custom URL for the HTML fiile, like this:

file:///home/peter/Documents/homepage/peter-home-homepage.html

That works. And I also have followed the steps on that blog post to customize my /usr/lib/firefox/autoconfig.cfg and my ../firefox/defalults/pref/autoconfig.js files. That's no longer working.

Did something in a recent version change? Is this no longer supported? Thanks for any ideas!

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?

Hello,

I am using the Flatpak Version of Firefox on Manjaro Linux. I have hardware accelerated video playback on Youtube for VP9 but not for H.264 on YouTube and Twitch. I can verify that with intel_gpu_top. My hardware should be capable to do hardware decode. You can see in the provided screenshots, that it should work from the configuration standpoint. Do I missing something here or is this maybe a bug? I can provide any further information if needed.

Hello, I am running Ubuntu 22.04 (Firefox v 121.0) on a custom PC. Ryzen 5700G, 32GB Ram, 2TB Storage, and a Radeon RX 580 (just to give some insight into the system in case it is useful). I use multiple mozilla services and haven't had many issues up until now. Everytime I open Firefox it immediately it fires right up, the moment I try to open a tab, search, etc.. it begins to lag. It will then freeze the browser and my entire PC soon follows suit. I have had to hard reset the PC about 3 times now. I originally had the snap version installed and thought that installing the deb package would fix the issue. I completely uninstalled the snap version and turned off unattended installations in case the system tried to reinstall the snap. I then installed the deb package and fired it up again, only to have the same issue. I have ruled out a couple of things on my end. I entered Firefox Safe Mode and unchecked all of my extensions (the only ones I run are Ublock, Bitwarden, and Relay). I ran a mem test and have been monitoring Psensor to ensure the CPU wasn't overheating (both of these tests were fine). I also scanned my entire PC to ensure I did not have any viruses (clamscan reported no viruses). I have been running my PC for about an hour now without starting Firefox and using Chrome, and I have had no issues with freezing or anything similar to what happened with Firefox. Not sure where to go from here. I love using Firefox and would love to get back to surfing as soon as possible! Any tips/help would be greatly appreciated! PS I could not find any logs about the session. I looked in ~/.mozilla/firefox/Crash Reports/events and couldn't find anything. If there is another place they are stored let me know and I would be happy to send them. I just don't want to open Firefox until I feel it is safe for my PC.

I forgot to add: I disabled hardware acceleration as well, did not fix the issue.

I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

I often see that some pages take up too much memory. This critically affects the performance of my laptop with 8 GB of memory. However, I was unable to reproduce this behaviour. Now I have caught two web pages.

https://linuxhandbook.com/sort-top-command/ 

and https://www.tutorialspoint.com/how-to-find-number-of-ram-slots-in-linux The first page quickly takes up 1-2GB and continues to drain memory. The maximum usage was 7 GB on a laptop with 16 GB of memory. This behaviour is the same in Firefox and Chrome. The second page quickly takes up 2GB, which is very noticeable on 8GB laptops. Why do these pages take up so much memory? Most importantly, how can you protect yourself from such an unexpected memory consumption?

How to save images to the downloads directory (that I chose in settings) without using right click -> save image as .. -> popup window .. then choose the location where I want to save it.

I tried alt+click, it didn't work, it saves the webpage url instead of the image. I prefer a solution that does not involve any add-ons.

Thank you.

I want to navigate on search results using the keyboard. I could use tab but it suggests all interactive elements such as news, images, books, videos, search settings and etc one by one. I want to press something and make active first result, then second. If such hotkeys are not provided, maybe there are any extensions with similar functionality?

Hi all :)

From a fresh Linux Debian Bullseye I try to connect to a local machine with Firefox (v97 64-bits) by its hostname (avahi server with default domain "local") with the port 6180 bound to a remote web service port (61 is the distant machine IP and 80 is the forwarded port).

When I want to open this URL : http://bionic.local:6180/ FF displays "We can't find this site ... Unable to connect to server at bionic.local ... check your network connection and firewall"

BUT ping bionic.local works perfectly and resolve the good IP address from the Chromium navigator the same URL works without a problem, I can open the distant web site.

This workaround works : add a static resolution in the /etc/hosts file : 192.168.0.71 bionic bionic.local => so FF works in the expected way for now ! But as I said this a workaround and a bad solution.

I supposed too the port was blocked because I accessed an unusual port. So I tried this without success.

How the hell make that FF v97 allows me to use an unusual port ? Or is it bound to the domain "local" which is no more accepted by FF ?

Thank you in advance for your help. With adelphity, lnj
