Firefox Support Forum

duplicate of /questions/1451035 thread.

Hello, I cannot log in to Twitter/x.com with the Firefox browser. There is a constant loop when registering. Firefox browser does not connect Twitter/X.com.

Thanks for your Help.

Since the penultimate and now the last current update to version 127.0.2 (64Bit), the button (tile with the + sign) to add new shortcuts is no longer available. How can new shortcuts be added now?

Hello everyone, I have had a problem for a few weeks on the X platform. Some buttons no longer appear, notably the edit button on an image post or the "see" button for a hidden account (see images attached) Does anyone have a solution? I uninstalled ALL the extensions and restarted the app, but nothing works! Thanks in advance

Starting with Firefox version 120, you can set Firefox to automatically launch whenever you start or restart your Windows computer. https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer

The browser shows opt-in prompt for the user to easily setup this behavior. However, I do not want to do this.

When I click "No thanks", the prompt goes away, but couple days later, it returns. I guess that an update resets the prompt status.

Is there a way to permanently disable this opt-in prompt without allowing Firefox to start automatically with the computer?

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

In my experience with the TF2 Wiki page, clicking an audio file link would open a new tab where I can play the file. Since I've moved to firefox, I can no longer do this. Instead, the file downloads. Is there a way to change this? I saw in another post that you have to change the flag media.play-stand-alone to true but it was already true.

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

I am trying to open a website but I keep getting error code 522. I've tried using Chrome and it connects to the website with no problem. I've checked my privacy settings and I do not have that website blocked. What else can I check? I don't think it's an issue from the website side.

Picture in Picture is an awesome feature and i love that Firefox comes with it by default.

However I do wish for one thing. So we can lock and "click through" the picture in picture, instead of our mice being able to click it by mistake when doing other things (such as grinding on an MMO or something.)

Is there any way to get these options in the near future? It'd be great to play some games when watching a video during slow times! Thank you!

Im currently reading books (pdfs) in firefox and I would like to hide the scroll bar. Im using full screen mode and especially the bar the the bottom is annoying while reading. I've seen a few topics posted about this issue but they are from a few years back and the solution posted doesn't seem to work anymore. (creating profile/chrome/userChrome.css with some code) But maybe the code is just outdated or I did something wrong. Im not too sure.

The best solution to me would be to just hide the bottom scroll bar. I didnt find any option in about:config except for making them (bottom and right) both thinner.

I would greatly appreciate any help.

I just started having an issue while watching Live Streams on Youtube with FireFox. I'll load the live stream and it will run for about a minute then it will switch to the streamers previous recorded stream. I opened Youtube on my iPad and on Edge browser and the Live stream keeps playing the live stream but on FireFox it only lets it run for about a minute before flipping the playback to the previous recorded video of that streamer. I tried clearing my cache for Youtube and I have no extensions running. I have Youtube Premium and run no adblockers. I have also tried safe mode but the problem persists.

Any idea what could be happening?
