Hello Firefox community, I'm having a problem where, when I click a link (in a pdf, specifically), Firefox opens like usual but for some reason, my keyboard gets disabled. I can click and navigate through pages that way, but I cannot type anything in the search bar, nor in programs (such as Drive). Does anybody know what I can do to fix this?

Turning it on again and restarting the browser makes it run smoothly again. I am using Xubuntu Focal Fossa LTS.

Anyone has any idea as to why this is happening?

Same problem with Manjaro on Raspberry Pi 4 - when "Title bar" is disabled video performance gets quite sluggish - I tested a lot to find out which one of my settings was problematic ... I don't know why this little modification behaves that strange, but it is quite a big deal for slow or energy efficient hardware ...

In previous versions of Firefox, I could view a web page with various links, and I could select a link to open in a new tab. Once I was finished in the new tab, I could close the new tab, and return to the original web page, and find the previously selected link because it still had a rectangle outline around it.

In the latest versions of Firefox, this rectangle no longer appears, so it's impossible to know where I was on the original web page.

Is there a way to get this feature back?

I'm doing some testing regarding mutual SSL authentication, and when I try to add the .pfx certificate that I generated, I get "The PKCS #12 operation failed for unknown reasons" as the error, and the certificate doesn't get added.

I tried this on another browser, and there was no problem regarding the usage of the certificate, so I can assure the certificate, its data, or the generation process was wrong.

I'm currently using Firefox 80.0.1 64-bit for Ubuntu.

Any help would be greatly appreciated.

I am a Linux user. So I have a folder called .moziila. Firefox use this folder to save settings and so on. If you are a Windows user you also have this folder C:\Users\<username>\AppData\Roaming\Mozilla.

So I have a folder (Linux) /home/name/.mozilla/firefox/rt7gtt8p.default/ (I will call it System Folder later)

If I would be a Windows user I would have this folder here: C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles\xxxxxxxx.default (I will call it System Folder later)

But I want to have a folder called "sessionstore-backups" in System Folder. I had it and I want enable it folder again.

How can I enable "sessionstore-backups" in System Folder? My goal is to have a file called recovery.jsonlz4. Without this folder Firefox will not create recovery.jsonlz4 for me. So I don't have a folder "sessionstore-backups" and I don't have a file called "recovery.jsonlz4" but I want to have it, but how? Maybe I need to add something to about:config?

I have a custom add-on that I'm working on for my team. It's hosted internally on a server signed by our company's internal CA. The add-on is signed by Mozilla, but not hosted on AMO.

I am on the latest version of Fedora running Firefox 81.0. In the browser console I get this error relating to the URL for the addon when I tell Firefox to check for updates: "Certificate issuer is not built-in".

I have the company CA installed and when I navigate to the site in the browser, Firefox recognizes the cert. I've done some reading on the subject and seen several threads about it. I've tried a few things already, but most of the threads where a couple of years old.

I'm asking the question here hoping to figure out what the current state of the problem is and which settings I should tweak to have it trust the company CA or what my options are.

Thank you in advance for any support on the issue.

I'd like to be able to remap most of the key commands in Firefox to be more ergonomic such as

  • Ctrl-h: select tab left instead of Ctrl-tab
  • Ctrl-l: select tab right instead of Ctrl-shift-tab
  • Ctrl-j: scroll down half a page instead of Space
  • Ctrl-k: scroll up half a page instead of Shift-space
  • etc

Is it possible to change these key commands by configuring Firefox or modifying its configuration files? I've considered setting up an external program to remap keys when the Firefox window is focused, and compiling Firefox from source, but I'd like to know if it's possible without doing this.

I use version 81 of firefox.

A new update of a website has disallow download of pdf. As the attachment I can only print pdf (or print to virtual printer) but I'd like normally save this pdf.

If I click with right key I can only save html (no pdf) and also use an external viewer I have same problem.

Any idea please?

Hi,

is there a way how i can let firefox open a link in new tab from command line for specified profile? Ideally in a way in which it doesn't matter, whether firefox is already running or not

I know I can do something like: firefox --new-tab 'https://www.google.com' this works no matter whether firefox is already running (just add new tab) or it's not (open firefox and add tab)

But what I want to achieve is something like this: firefox -P myProfile --new-tab 'https://www.google.com where myProfile is existing profile.

This works unless firefox is running with that profile (opens new instance). But if it's already running i get the error message (Firefox is already running but it's not responding. To use firefox you must first close the existing firefox process, restart your device, or use a different profile). I tried it with/without --no-remote options but it didn't help

I want this for a script that should open pages automatically but not in the default profile. And it should be able to work even if the profile is already running.

Thanks for any advice, Jaymes

Persistent performance problems starting ~6 weeks ago

Hey there, I and my colleagues who use Linux have all started seeing massive performance decrease & tabs frequently reporting "a web page is slowing down your browser" issues starting around August 5 or 6 of this year. I started a complaint thread in my company slack about this on August 6, and unrelated to that, someone else started a similar thread on august 18.

At first I thought it was just me, or just some quirk of my linux distribution, or a pattern of using the software. But I actually switched Linux distros from Ubuntu to Arch to see if it would help (it didn't) and now that I've seen the behavior consistently across a whole bunch of different apps, I think it's a bug. It seems to affect heavier webapps like Quip and Slack, much more so than lighter webpages. Again, nothing was wrong before August of this year and now, depending on how I use my computer, I frequently get "a web page is slowing down your browser", cpus pegged to 100%, which ends up with me closing tabs/ sometimes restarting firefox multiple times per day.

Nobody on Chrome is complaining about similar issues.

I did run the profiler for a bit while such an issue was going on, and am happy to share it, although it has slightly-private information from one of our company slacks and I don't know if this forum is public.

Hello, I have the problem that when filling out "email" in a form on a website everytime I write the @-sign everything written in front of it get's deleted. I found out that when I press the "Alt-Gr"-key the word I wrote get's marked and of course then the @ deletes the marked word. How can I keep "Alt-Gr" from marking the active word? :-) Also the same word marking happens when pressing the "Alt"-key. The same happens in Thunderbird when trying to write a new email. I'm working with Ubuntu, but I doubt it has to do with Ubuntu, because when filling out a form in Opera it works just fine. Any help appreciated! Cheers! Formicula

Even though Firefox 80 and 81 release notes doesn't say anything, many websites stated that hardware acceleration on Linux X11 was introduced in Firefox 80, but disabled by default, while it was enabled by default in Firefox 81.

This is what I see in my about:config and, honestly, it's definitely unclear (using Firefox 81, of course):

HW_COMPOSITING available by default / blocked by env: Acceleration blocked by platform OPENGL_COMPOSITING unavailable by default: Hardware compositing is disabled WEBRENDER opt-in by default: WebRender is an opt-in feature WEBRENDER_QUALIFIED available by default / denied by env: Not on allowlist WEBRENDER_COMPOSITOR disabled by default: Disabled by default WEBRENDER_ANGLE opt-in by default: WebRender ANGLE is an opt-in feature WEBRENDER_DCOMP_PRESENT opt-in by default: WebRender DirectComposition is an opt-in feature OMTP available by default WEBGPU disabled by default: Disabled by default / blocked by runtime: WebGPU can only be enabled in nightly

What should I understand from this? Sounds like it's all DISABLED on my system (Linux Mint 18.3, based on Ubuntu 16.04, Intel Haswell integrated GPU). Why!?

Also, what is the right way to enable some hardware acceleration now? OpenGL, WebRender, FFMPEG/VAAPI... it's a real mess. Until some versions ago, I simply used layers.acceleration.force-enabled=true and this enabled OpenGL hardware compositing. But what is the right way to do it now?

Why can't Firefox developers simply add an option in Preferences to enable or disable hardware acceleration!? The only current option "use hardware acceleration when available" doesn't mean anything. I have been using OpenGL hardware compositing with layers.acceleration.force-enabled=true for years with no issues at all, yet Firefox always decided that I should not use any kind of hardware acceleration on my system... Quite disappointing.
