Original question:

> I want the new tabs to open next to the current tab and not at the end of my 644 tabs. Use to open next to the current tab and then I had to reset FF and now I can't get it back the way I had it. What do I need to add or change to get the behavior I want and had?

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.

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?

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!

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.

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!

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.

Firefox 89 on my Raspberry Pi 4 is displaying what I'm guessing is a codec issue. Videos can be watched but the picture is corrupted by brightly coloured patches around areas of detail.

Prior to the version 89 upgrade, version 88 was working perfectly.

I have Firefox 89 on a Raspberry Pi and a PC. On the PC it still works perfectly, on the Pi video is displayed badly.

On the Pi Firefox 89 is running under Ubuntu 21.04. On the PC Firefox 89 is running under Ubuntu 18.04

Am I alone in this or have others seen the same issue ?

Assuming I am not alone, does anybody have any idea what has gone wrong ?

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.
