Whenever I try to watch a video on YouTube, Firefox would automatically set the playback speed to max, mute the audio, and the video would just end (as if someone moved the seek pointer to the end). Since my YouTube is set to automatically play the next video, I would be presented with a screen showing me what the next video would be playing. At this point, I need to do the following:

1. quickly click cancel
2. hit the replay button
3. set the playback speed to anything but normal
4. set playback speed to normal
5. unmute audio
6. move seek pointer back to beginning

From this point on, videos would play normally and I can jump around and watch different videos. But once I close Firefox and restart it, it would reset to the above issues (max playback speed, mute audio, skip first video).

Anyone else having the same problem? Anyone know what's going on?

On a tangent, on my Windows machine, every now and then, Firefox would flash a white blank screen. I would be surfing and reading stuff and all of a sudden, the screen would just go blank. After a few seconds, it would come back. This only happens on my Windows machine and not my Mac.

Hey,

I constantly have unreadable fonts in Firefox for Mac. This only happens since I started using a new Mac (M2 Chip).

I know there are some "solutions" flagged but I cannot get it to work. My main issue is, the inspector it self has completely garbled fonts. So does the elements of the browser itself, for instance my favorites bar.

I know I am supposed to check my fonts, but I don't know how? I used the fonts application on my mac and let it validate the fonts. No issue there.

Only thing to resolve this issue is to reboot. And this is extremely frustrating since it means out of the blue my Firefox won't show fonts and I have to save all my work and reboot to be able to use it again.

I would highly appreciate a step by step solution on how to fix this. It seems to be a common problem so maybe there is a solutions that describes it better than the text I found here to inspect elements and check fonts.

Thanks in advance.

Before Firefox used to keep private tabs 'open and available' till you closed the page out, for iphones, ipads, etc. Now all my private tabs are closing out every time I close the app. Before there used to be a section in settings that would allow you to turn this feature on/off, however it's not in settings anymore. I wanted to know if there is another way around this. I want to be able to keep private tabs open when I close out Firefox on my phone and ipad.Before I would have all my tabs available jut like regular browsing but now its cleared out evey time. Is there anyway to fix and change this?

Hello,

I noticed something strange on my account under my password manager and want to make sure it is not a security issue.

Under my Password Manager, I noticed that a majority of my saved passwords (unless used recently) all have the last "used" date as April 5, 2024. These are on accounts that I do not access frequently and they all have the same "used" date.

Why would this be the case?

Thank you so much, Brianna

I am a long-time Firefox for Mac user and recently, browser APP all of a sudden is ignoring selected PRINT preferences. Two examples are: Printing one-sided when two-sided is selected, and printing in color when the default and selected preference is for a "Black and White Fast Draft". I use a MacMini M1 running Sonoma v14.5 and Firefox v 127.0 (64 bit). My printer is an HP OfficeJet Pro 8710 with up-to-date firmware. I have resorted to use of Chrome until I resolve this situation, though I prefer to use Firefox. In addition, while it may be a separate issue, I also found that the use of Firefox when using GMAIL developed a new issue at approximately the same time. Now, when clicking on the selection box for an individual email, Firefox often does not allow the box to be checked, but again with Chrome, it works just fine. Any help would be appreciated. Thank you.

I upgraded from 126.0.1 to 127 today. Upon update, all my windows are gone. The only way I could access them is to revert to an older profile backup and reinstall 126.0.1.

I tried exporting my session with Tab Session Manager in 126.0.1 and reopen them in 127, but that only restores the last tab of each window (oddly). The json clearly lists 3 windows each with multiple tabs. I tried copying the sessionstore-backups folder, but no dice.

I've been dealing with this issue for a long time now, without finding any solution

On macOS, whenever I am using Bluetooth headphones (Sony XM4, Airpods Pro), videos will hang for a few seconds just as the video is starting. This happens again if I pause/unpause or if I seek forward/backward on a video. The video "spinning animation" will appear and it will take 2-3 seconds for the video to start. This happens immediately, even if I click pause/start fast (ie: this is not after some delay necessarily). Also, if I mute audio on the video, the issue does not manifest itself.

During the waiting, Firefox itself seem to be hanging: for instance if I click on an extension icon in the toolbar, nothing will happen until the video finally start playing and then the extension menu will open up

When using Google Meet or Zoom for instance, I sometimes have to wait up to 10 seconds or so before Bluetooth Audio/Microphone starts after I've joined a meeting.

The issue is not specific to these platforms: I experience the same issue on other platforms such as Facebook, dailymotion, vimeo, zoom. On Facebook, since videos start muted, I can see the videos start playing right away, and then if I unmute sound the video stops, and start again with sound after 3 seconds or so

The issue does NOT manifest itself when playing an audio-only stream: ex Soundcloud or local radio stations audio stream

Things I've tried and didn't help - Troubleshoot mode - Different Firefox profile - Different Firefox install - Restarting my system

This feels like Firefox/macOS is waiting for Bluetooth to activate, or something like that. I have a feeling this only happens for certain types of video/audio codecs but I am not sure how to validate that (ex: no issues on soundcloud, petron audio-only posts).

The problem is entirely non-existent when I'm using sound output that is not Bluetooth.

This does not happen with other browsers otherwise I wouldn't be posting here :)

I receive e-mail from websites where I subscribe. Many times, the message from the sites (kelbyone.com, to name one) contain a graphic (jpg) that does not display in Outlook.com. Microsoft Tech Support is unresponsive. The sending websites refuse to help.

It seems to me that FF chokes on the length of the hyperlink. Here is a sample: https://kelbyone.acemlnb.com/lt.php?x=3DZy~GE2JaTN5XV.-wy5heOd~nAnuwAjluw2Z5PEIaOb5p8qy0y.0uJz2nRzit~yjvYwXncWJXCf657

If I paste the hyperlink into the search window, the page will load. When I forward the e-mail from Outlook to yahoo mail, the image displays.

I am running extensions Adblocker Ultimate and DuckDuckGo Privacy Essentials.

I would like help with this, at least, to identify where the problem is.

Hello,

I cannot open the uwyo.edu website on my Firefox browser. I have no problems with other browsers. I tried and checked the solutions people shared, but none of them worked for me. I checked the DNS and different networks, and I also checked the link below:

I would appreciate it if you could help.

Thank you and best regards, Farshad

On my Macbook (macOS Sonoma 14.5), Firefox blocks populating parts of some websites whereas other browsers don't. For example, on my J. Crew Factory website account, when I click on "Order History," I get a blank page. Other browsers (Safari, Brave) correctly populate the info on my Order History. Why does Firefox block it?

This is not a bug or issue, rather a use case question. I have a webpage with information and I don't want to accidentally click or submit anything on the page.

This could also be considering having a form etc in draft form as view-only so you go into "View Only Mode" and work the webpage as a reference etc. without having to worry about any accidental submission or mistakes.

If someone knows of Add-ons or how we can achieve it with FF, it would be much appreciated. Posting, since I expect to have this case often.

I accidentally closed my Previous Tabs Session and am unable to find them. I've tried some of the online tips but am still unsuccessful. Is there somewhere on my computer where I can find the previous tabs that I had open in Firefox?

Thank you, Massimo

Is there some way to enable and disable specific config settings , on a per-site basis?

For example, let's say I want to disable right-click hijacking (dom.event.contextmenu.enabled) on turtlesaregreat.com, but use the default settings everywhere else.

The Page Info > Permissions panel has some, but not all the ones I want. Is this somehow built into Firefox, or maybe there's an extension?

Thanks.

I keep getting prompted to sign into my Firefox account, but when I type my password and hit enter, the prompt clears out my password and nothing happens. I'm already logged in to post this question, so I'm confused as to why I keep getting prompted.

I've tried:

1. Numbered list item Removing the account, but the same unresponsive password prompt shows up
2. Numbered list item Reinstalling, but same issue
3. Numbered list item Resetting password, but same issue

Potentially related: I am successfully logged into my Firefox account on another laptop, and I'm seeing no prompts there. Any ideas what else to try?
