Firefox can take screenshots of pages or screenshots of custom areas of pages.

According to the documentation, when we download the image, the filename should follow the pattern: Screen Shot yyy-mm-dd at hh.mm.ss.png. If I use the :screenshot at the console, the pattern works as documented.

But Firefox is using a different pattern when I choose Take Screenshot from the context menu. The pattern includes the page's title. Example: Screenshot 2024-04-14 at 18-35-16 General ‹ Settings ‹ Geomaster Lda — WordPress.png.

Since the page title can have non common filename characters, I have problems with such filenames. My uploads to MediaWiki fails with such filenames. I know I can report or improve MediaWiki, but my question here is quite simple.

Can I change the Firefox's default pattern for Take Screenshot's downloads?

I am autofilling an ELSA payment portal. Firefox autofills the payment information correctly. But the program will not recognize the autofilled information and doesn't let me process the payment. I then overwrite all my information and then it allows me to proceed with the payment. I have used the same procedure for years but as of this last week, the autofilled information is not recognized as I click the "Continue" button after the autofilled info is complete, and it won't work. The ELSA source (State of Wisconsin) person said it's a browser problem on my end. No. The online form autofills just fine. Can anyone help? Thanks. Jeff

So on my macbook when I enable fullscreen the anmation is super weird. first it stretches the video to the top and then just expands to the whole screen, when I go out of fullscreen is stretches to the bottom and then goes out off fullscreen. for example on safari it just expands the video until it takes up the whole screen. I have gone in about:config and disabled the fullscreen animation but that did nothing.

I had to reinstall windows and it wipe Firefox.i didn't know my password so I resetted it. Problem is it wiped all my data. Didn't know changing passwords for forefox would so this. Anyway I can get them back?

I've got a really old MacBook Pro that's still running 10.13, and Firefox has started displaying a nag screen telling me that this version is no longer supported, and to install a newer version of MacOS.

Is there something in the advanced settings that will stop it nagging me? I now know it's not going to get any more updates, there's no need to keep telling me every 20 minutes...

(Note to the devs: a "don't remind me again" checkbox would be nice for things like this!)

I have not been able to highlight and copy ~ even prior to the most recent update.

Even using control/ does not work.

Really hating this.

Hello

I want to use extension xpi's from a shared external folder over multiple Linux profiles. So i examined the profile folder and found extensions.json. Though i can't find any documentation to it's keys online.

There's "rootURI:" with a "jar:file://path/to/extension.xpi!/", so i tried just replacing the path with the shared one. Though i observed that just makes firefox replace the path with the current one. So i examined further and found the "location:" key with the default value "app-profile". So my guess is, there's other values for other usecases, right?

So, in summary, what i need is:

• documentation to extensions.json keys or possible values to "location" key.
• if that isn't intended/doesn't work, how i can achieve my goal otherwise.

And please don't suggest the sync feature, that doesn't work for my usecase.

Download files (pdf, xml) don't open in application (acrobat, firefox) since 125.0.1 Firefox version from IBM Power server with Ubuntu :

The message is "Fichier non téléchargé - Risque de sécurité potentiel" that is "No downloaded file, potential security risk" :

When we download a pdf file from the server, the "choice box" allow to . open in the browser or . open in Acrobat or . download on my PC. The opening fails with this message. This is the problem. The download on my PC works and when I open the file from my PC it works also.

We need this function of opening a pdf or xml directly from a server IBM Power with Ubuntu. It was OK for several years until 125.0.1 Firefox version. We had no change on the IBM server.

Can you repair this problem quickly. My PC uses Windows 10

Thank you Patrice Castejon [removed phone#]

In Proton Mail, when I receive an email with an picture attached inline, I get the following error message: "Your browser could not verify the remote server's identity. The image might be hosted using the http protocol." Is this issue with settings in Proton or Firefox? How do I fix this? See image below. Thank you.

All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

Picture-in-picture since recent YouTube update keeps closing. Is there way i could configure in about:config to never close and always stay open even if page refreshes and have it move the video play back always to the Picture-in-picture window ? If not could this be made a feature in a future update ?

YouTube especially been annoying to Firefox users, cos it keeps refreshing the whole page breaking stuff every time it plays the video, as well have issues with looping videos even tho they are already fully buffered, making entire YouTube experience as frustrating as possible as encouragement to switch to chrome, which i refuse for obvious reasons.

Anything i can do on my end ? If tested if this happens in incognito mode as well with all extensions disabled in private windows, no change of behavior.

Btw this happens on the new YouTube interface with no way to get back to the old interface, cos it keeps the annoying features of the old interface even if you try to re position stuff using hacky ways like extensions that do so, which of course break stuff even further. I just want Picture-in-picture to remain open, and to play current video in picture-in-picture that is playing automatically.

Btw the Picture-in-picture experience with chrome or chrome based browsers is absolutely horrible, giving me even more reasons to stay on Firefox besides privacy related issues and other issues.

So I'll be typing like normal (I type 100 WPM), and all of a sudden, I'll type a sentence, but each individual letter starts taking about 3 seconds to show up on the screen. I have to sit and wait a super long time for everything I typed to finally show up. Other times, I move my mouse over something I should be able to click on, and have to wait a long time for the arrow to turn into a hand, letting me click on it. These periods of slowness will last a few minutes, then disappear.

What's really interesting is that when the slowness starts, I can type just fine up in the URL bar. I might type my entire message there, then copy paste it down to where ever I was wanting to post it. However, when I do that, if I have another tab open and that tab is playing music, the music will start to break up and lag as I type. Again, after a while, the slowness disappears and we're back to normal.

Can anyone tell me what's going on?

Hi Every single one of my passwords is compromised according to you. Therefore I think the data breach is with Firefox . I have set up several unique passwords recently - how are they breached so soon? And why every single one. It is very suspicious. Regards Caroline
