Hello, how to make my vaapi work when i see youtube videos in Firefox 91.0.1? I tried change some flags, example

• media.ffmpeg.vaapi.enabled = true
• media.ffmpeg.vaapi-drm-display.enabled = true
• media.ffvpx.enabled = false

and it doenst work..

but my vaapi work with my brave browser (chromium 93 build)

in about:config page the options: browser.tabs.warnOnClose (true - default) browser.tabs.warnOnCloseOtherTabs (true - default) browser.sessionstore.warnOnQuit (false - default) browser.warnOnQuit true (true - default)

But when i do Ctrl+q accidentally, it closes the only Firefox window i have. This window has many tabs open. Yes it restore next time, but i want FF to ask me before closing it.

FF 84.0.1 Arch Linux

I store all of my passwords in Firefox's "Logins & Passwords" feature. Even for things that are not online in any way. Whenever I need to create a new login & password record for something online, Firefox will automatically generate a password and give me the option to fill that into the new password and confirm new password fields. For anything that's not online I open Firefox and click the "Create New Login" button and fill in the details. I then go to a site online that generates passwords for me and fill that into the password field for the new entry.

Is there a way to get Firefox to offer a newly generated password at this point?

I normally use Firefox desktop on my Linux computer.

Last week, I started using it on a public computer running Windows. I installed Firefox Portable and then logged/synced into my Firefox account on this Win computer. I noticed that in the Firefox Portable Windows “about:preferences” page, it says “Your browser is being managed by your organization”, which links to about:policies. In that “about:policies” page, it shows this https://i.imgur.com/JmD8nXg.png Policy Name: DisableAppUpdate Policy Value: true. Now I’m back on my Linux desktop computer and it also has this “managed by your organization” message in “about:preferences” and the same “about:policies” stuff. In other words, it appears that this policy was copied from the Windows public computer to my personal Linux computer. I don’t want that.

How can I undo this? And how can I block this sort of policy syncing?

Hey all,

I upgraded firefox to 89.0 (firefox for ubuntu). When playing videos it now uses RDD process instead of Web Content. The problem however comes from the resources "RDD process" uses. It is consistently at 100% usage of a CPU core and this is causing my fans to be really loud. I fixed this by changing media.rdd-process.enabled to disabled in about:config and this fixed the system resource issue but I don't think this is what is meant to happen.

As far as I know "RDD process" is meant to use the GPU. My computer has a dedicated GPU so I am at a loss as to what is going on here. Anybody who has any idea?

Thanks in advance.

Hi - I see that SetupVPN is free. I'm not very technically oriented and wonder if it's safe and also how can it be free and still continue? I'm on a COVID budget, but I like free as long as it's safe. Does anyone have any info on this? Thanks very much for any help. Regards, George

Hello everyone, I'm working on customizing the Firefox experience for users within my organization.

I have to really limit their access. One of those requests were to prevent users from minimizing their active Firefox window.

I've found articles like the one below that show how to hide all the buttons: https://support.mozilla.org/en-US/questions/906698

However it does not suit the purpose. since it removes all of them and only on full screen.

Is there a way I can just hide the minimize button so that the user can just hide the minimize button?

Any help would be greatly appreciated.

Hello,

I've spent several hours today trying to fix FireFox slow start up on my system. After start up (about 2 full minutes), everything works normally. The hardware is an ASUS A88xm-A MB, A10-6800K processor, 16G DDR3, runs OS and programs off an SSD. I worked through all the slow startup suggestions, ran memtest (0 Errors, 1 Pass), disabled all add ons, (even the OpenH264 video codec (I use the onboard HDMI, no graphics card)), turned off hardware acceleration, etc. When starting in troubleshoot mode, less than 30 seconds, (acceptable), but I really don't know where to begin with the "More Troubleshooting Information" when I look at the table generated by it. There have been no other problems to date with the system, and the long start-up time began with 20.04 Ubuntu (about a minute), then got worse when I upgraded to 22.04 to try to solve THAT problem. Currently running FF 104.0, and the update page says wait for a distro update if that is how it was installed. I believe 104.0 is the latest Linux 64b version though. All updates to the system are done as soon as I'm notified of them. there have been none since the upgrade a few days ago.

Any suggestions? Gotta get some sleep now... TIA, Dave

When I download a file and click on the downloads button to bring up the Downloads menu, I often just want to open the Linux Mint file manager in the right folder so I can move the file to a more appropriate place.

In the menu, there's the little button to the right of the listed downloaded file with "Open containing folder", but if I click on that, FF opens the downloaded file, not the file manager.

Obviously this wasn't always like this, but I don't recall doing anything that might have caused the issue. How can I set FF back to the default action of opening the Linux Mint file manager?

Thanks!

Firefox needs a limit on memory usage. I was developing a tiny web page on Linux (PopOS) and accidentally created an endless loop in Javascript that ate memory (by growing an array). My entire OS became inoperable and had to be hard-rebooted. I was surprised this could happen due to Javascript (a sandboxed browser language), running in a web page (a sandboxed app) running in a Firefox browser that is supposed to protect users from the world wild web. One errant line of legal Javascript in HTML should not equate to a denial-of-service attack.

A sensible approach would be similar to the nice warning given when a script takes too much CPU, offering the user the choice to continue or stop the script when a tab exceeds some reasonable size: a fixed MB size, or say 10% of real RAM memory.

Ideally there should also be some hard limit calculated by Firefox according to the machine's available memory and Firefox's reasonable percentage of it. For example, maybe limit Firefox (all tabs combined) to 50% or maybe 75% of real memory, so that the O/S has a reasonable chance to remain operational so that a bad tab can be closed. Otherwise, Firefox could cause the O/S to lock up, resulting in data loss if there are tabs or other apps outside of Firefox that have unsaved changes.

Thanks for your consideration!

Whenever I zoom into images in Firefox (example), the image smoothing makes them look blurry, especially on low resolution images. Is there any way to disable image smoothing of Firefox?

I open the terminal (I'm using FreeBSD) and I run: `firefox --help` and I get a lot of command line options. However there seems to be no way to simply get the user agent string. This is kind of annoying because I might want to plug the current version of my Firefox browser in some automated scripts. At the moment I need to open Firefox, then go to the console and type in: `window.navigator.userAgent` copy the string manually and paste it wherever I want to use it. It would be really nice if there could be an extra option to the `firefox` command, like: `firefox --user-agent` that prints this information in the console. Maybe there's a way, if it is it must be really hidden because I couldn't find relevant information on how to do it.

Kind regards, Lucas.

Followed community advice but the following fails to work.

https://support.mozilla.org/en-US/questions/1306797

1. open "Help -> Troubleshooting Information" & find button to access the profile folder

2. find this button under: Application Basics > Profile dir > Open directory=/home/ab2qik/.mozilla/firefox/p3bbumtq.default-release click this button to open profile folder in Explorer

3. create a dir=chrome in this folder(all lowercase) 4. In dir=chrome create a text file=userChrome.css(all case sensitive) 5. userChrome.css - paste in text below 6. paste below code into chrome/userChrome.css:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

1. personal-bookmarks .toolbarbutton-text { font-size: 15px !important; }

7. (Quit/Exit) browser & restart Firefox when you create or modify the userChrome.css file.

8. Firefox 69 & later

about:config > toolkit.legacyUserProfileCustomizations.stylesheets = true

set above pref to true this enables userChrome.css & userContent.css in chrome folder

After a crash, or even after shutting down the computer without closing all Firefox windows, Firefox will restore all the windows and tabs from the last session on restarting Firefox.

There can be many reasons why this may not be preferred behaviour for many users: Sometimes Firefox or the computer crashes because too many windows and tabs are open (and other applications running), killing Firefox may be a measure against malicious pages trying to hijack the browser, discarded pages after shutdown do not need to be restored, ...

So is there a way to make Firefox immediately ask whether to restore the session, like it already does after the second crash? This should actually be an option in the settings.

Using Firefox version 102:

Open console tools and navigate to Network tab Right click on a POST request "Edit and Resend" is no longer an option? There is still the resend option Clicking resend allows you to edit the request, but unfortunately the "Content-Length" attribute is not automatically updated like it was with edit and resend, so all requests fail after being edited. This is because the Content-Length header indicates the size of the message body, in bytes, sent to the recipient. When you add or removes bytes in a JSON request for example, it doesn't get updated. The attribute can also not be manually set. How can I use version 102 to edit and resend requests the same way I used to?

Thank you.

Hello everyone, I have always been a fan of the sync feature. i have 3 devices i use everyday with my tabs open between all of them. now, just recently i switched to linux and ported over my 500+ open tabs using the sync feature by just clicking "Open all taps" button. while playing around i missed up the os and had to reinstall it. now i am here in firefox looking at my synced tabs little window and there is no "open all tabs" button anymore. where did it get moved to? i looked everywhere and i couldn't find it. i cant just spend two or so hours opening all my tabs manually...

Thank you for your time.

I upgraded to Ubuntu 22.04 recently. Since then Firefox 104.0.2 (64-bit) has been arbitrarily freezing; sometimes i have to restart the computer while most of the times I am able to kill the Firefox main process and restart Firefox.

The freeze occurs when i try to save a Web page; i don't see any "logic" as to which Web pages cause Firefox to freeze. It seems totally arbitrary.

I clear my downloads list everyday (sometimes more frequently than that) and clear cookies & cache everyday.

I have selected "no proxy" by default, in 'Connection Settings'.

This never happened until after i upgraded to Ubuntu 22.04.

I've browsed the support pages and don't find anything relevant to my problem. If I'm overlooking something, I apologize in advance!

I have attached a 'screen capture' image of Firefox processes just before i killed the main process.

Thanks in advance for any suggestions. Ramki

There are some browser games that are best played full screen, but I can't seem to find a way to keep the "helpful" menu from popping up over my game when the mouse hits the top edge of the screen. The best I can do is not play full screen, and detach the tab of my game to minimize the amount of tabs visible (and clickable) but there are still these "landmines" on the screen that actively sabotage playing the game without having the handicap of firefox taking over and messing with the screen.

Is there any way to completely disable the popups from a fullscreen mode, show no toolbars, tabs, or anything else (except when exiting fullscreen mode via the keyboard.) I want the mouse to have no interaction with changing the display except for the game itself.

Playing http://slither.io is a good example of what I'm talking about.

Thanks!
