I'm attempting to set up sync between my windows laptop and my new android phone. The phone has firefox loaded, allows me to pull up the 'sync and save your data' page, allows me to choose 'ready to scan' and presumably successfully scans the QR code displayed on the laptop (the laptop prompts me to approve the new device). Then the laptop indicates I need to wait to approve it on my phone, and the whole process stalls. The phone continues to display the mostly blank white screen with only the "moz://a" at the top and the spinning blue circle in the center. Eventually the whole thing seems to time out and I receive an error message on the laptop saying "websocket unexpectedly closed" and "device pairing failed".

My two hypotheses are that either still having my old phone (which is being retired to at-home use only, and I'd rather not de-sync) still synced is somehow interfering (seems unlikely), or that something about the new phone's software is interfering in the sync (seems unlikely and way out of my league in terms of troubleshooting around).

Help please?

I've been having a problem with FF for the last two weeks. At times downloads accessing web sites are slow or even get hung up. Usually reloading or refreshing the page fixes the problem. I tried a FF safe boot and things seemed to work better. I have had the same four extensions for quite awhile. Are there any reports of UBO causing issues?

There's a bug with Firefox 134.0.2. where I keep getting logged out of certain websites, even without clearing my cache.

Is there a possible fix in the works for this issue?

I am trying to access certain HTTPS websites and some of them show PR_CONNECT_RESET_ERROR in Firefox. This error is not present in Edge or Chromium.

Here's what I've tried (none of these works):

• DNS over HTTPS turned off
• Uninstall all add-ons
• Reinstall Firefox
• Create new profile and set it as default
• Delete/rename certs.db in the Firefox profiles folder.

The only fix that works is to use Troubleshoot Mode every time I visit these websites which is not practical. Any ideas on what could be the problem?

I don't know if this is relevant but one of the websites that does not work is https://alexan.com.ph/

In some pages, redaer view shows the wrong text -- it looks like it picks up text from a hyperlink. An example is this page:

where Reader View shows the text from:

(which is linked inside).

I am using Firefox 134.0 on MacOS (Sequoia 15.2)

When we are getting dates and time in history like Chrome? Random months and in those months, no days, no dates makes Firefox outdated.

Is Firefox not growing or everything needs to be highlighted? I have never highlighted anything to chrome yet it has done things that are worth it.

I've recently done a clean reinstall of Windows 11 and have noticed that, only for Firefox (134.0.2, build ID 20250120135430), a few videos playback without any audio, yet the same videos play with audio when using edge as a comparison. Most (if not all) of these videos did play with audio in Firefox prior to this reinstall.

Firstly, I'm pretty sure this is not a windows sound mixer issue since many videos on the same page and tab play back with audio just fine in Firefox. The same goes for it not relating to the Firefox setting 'Speaker selection', under (burger) > settings > privacy & security > Permissions because videos of different formats (or using different players) on the same page play back audio fine. The tab is not muted. Again, some videos on the same browser tab play audio fine; some of a particular format or player only play the video, while missing the audio (and where Edge plays the same video with audio).

Another common and potentially relevant issue I've seen is that, this being a 'Windows 11 N" install, it was initially missing the settings > system > optional features > Media feature pack, but that is now something I've successfully added. I should add that windows did report problems when I initially tried to add the media feature pack but, after a very long delay, it eventually appeared to succeed when I ran a couple of DISM incantations that I think ended with - "dism /online /add-capability /capabilityname:Media.MediaFeaturePack~~~~0.0.1.0"

I have the 'Play DRM-controlled content' setting enabled.

Comparing the Firefox vs Edge video playback on this video test page - https://tools.woolyss.com/html5-audio-video-tester/ I get the following results (don't know how to get it formatted/aligned correctly, sorry) -

                           FF vid    FF audio    Edge vid    Edge audio
av1-opus-sita.webm          Works     Works       Works       Works
vp9-vorbis-spring.webm      Works     Works       Works       Works
vp8-vorbis-sintel.webm      Works     Works       Works       Works

avc-mp3-sita.mov            Works     Works       Works       Works

And perhaps also relevant is that there's also a difference in the audio-only samples further down the table on the same page -

                   FF audio   Edge audio
audio-sample.mp3    Works      Works
audio-sample.weba   Works      Works
audio-sample.ogg    Works      Works
audio-sample.opus   Works      Works
audio-sample.flac   Works      Works
audio-sample.wav    Works      Works
audio-sample.m4a    FAILS      Works
ac192.mp3           Works      Works
spoonradio-hd.aac   FAILS      Works
audio.opus          Works      Works

Also, every 'v.redd.it' / reddit-video-player video plays the video fine but has no sound when using Firefox but plays both sound and video fine with Edge. Here's one for example - https://old.reddit.com/r/funny/comments/1i7y1nr/rock_paper_scissors/

I've seen lots of similar (but not identical) issues on Firefox video with no audio problems with suggestions a few things to try. In addition to what I've already mentioned above, I've tried the following without success -

- Restarting Windows - Restarting Firefox - Restarting Firefox with addons/extensions disabled - 'about:support' > Refresh Firefox - 'about:support' > Clear startup cache - (hamburger) > more tools > task manager > (click the little profile icon for the page playing the video) - I've checked the settings suggested here: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings

I realise it may be possible to side-step this problem by flailing around with more drastic work-arounds like trying a clean re-install of Windows or a full uninstall and clean of Firefox, but that doesn't really help figure out the problem, which leaves the possibility it could easily happen again to me or others when it might be something that can be more properly fixed or guarded against in Firefox itself, so I hope someone can suggest what might be done to home in on identifying the cause of the problem and so learn whether a more precise fix can be employed.

I am an academic. I use Canvas. When I am in Canvas and I try to open a document in it from Firefox, what I get are solid black pages. I do not have this problem with Canvas in Chrome or in Edge. I really don't want to use those Browsers. I actually have this problem with every PDF I try to open from all sites. This is a recent problem. But if I cannot correct it, I will have to use other Browsers.

Whay have extensions stopped workong with latest Firefox update. E.g. Last pass is listed as an installed extension but clicking in the installed list just gives a settings page, and there is no button to enable pinning to the top bar, so I can't access Lastpass at all in this way. Have updated Firefox to 134.0.2 and reinstalled the Last Pass extension but no change. Previously I have been able to pin Lastpass extension to the top bar next to the Download icon. Other icon that do work: Pocket, Download, Account, Noscript, Duckduckgo search, ABP and jigsaw piece. When will this get fixed pleased?

I am unable to use Fidelity Investments using Firefox Version 134.00. Just says "Service Unavailable" this site always worked with Firefox in the past. No problem when I use Safari.. Anyone else having this problem.

See attached screenshot. It just randomly happens from time to time, and I can't figure out what's causing it. I've used both Chrome and Firefox with the same results. Help!

I have searched Support, enabled media Autoplay for all sites, Page Info for individual sites. Videos play but never with audio. Currently using FF 134.0 (64-bit) on Debian 12, but recall some problems starting about the 133.0 update. No audio with Youtube, Amazon testimonials/reviews, etc.

Please help?

https://shop.sportsbasement.com displayed and work 3-4 days ago. Now blank. https://us.muc-off.com/ blank https://www.asp-usa.com/ blank https://byrna.com/ blank

I have cleared cashe, history, Turn VPN off, Turn adblocker off, these were all on when it worked. Now nothing

A business website has a page that allows me to see items scanned to their server for the last 90 days. The server hosting this page takes more than 1 minute to begin loading to the browser - the back and forth symbol in the browser.

I timed this event today, and Firefox times out after 1 minute. My work around is to use Chrome with the same webpage and it took more than 4 minutes before images started to arrive.

It would be handy to have the timeout adjustable in the settings tab of Firefox. If I choose to sit on what I know is a very slow website for 5 minutes so be it.

Let me know what adjustments I can make - 400mb internet, 5ghz hard wired to the router. This is the slowest site we ever access.

After using the "recent browsing" menu in the top left corner of FF and opening certain websites from the "import tabs from other devices" menu it has completely broken a handful of websites on my PC entirely, even using other browsers.

The page will load but no content is displayed, no links or media, just a blank white page. This is consistent among these websites even among other browsers including Chrome and Edge.

I have uninstalled and reinstalled FF multiple times, cleared cache/history, hard PC resets, refreshed FF, Uninstalled and reinstalled every browser. The issue persists.

These websites still function perfectly fine on mobile FF and Chrome. I've exhausted website permissions, app permissions, etc. The issue still persists. These websites were functioning just minutes before I tried importing them from the other devices tabs. Something about that functionality has completely broken them on my PC.

Hello, I am suffering from an odd issue when using twitch.tv. In short, when viewing peoples streams, my video feed will usually turn into colorful static (aka "clown vomit"). I suspect that the issue is coming from Firefox, but I can't be certain. I am using a newly-bought laptop and the issue could be caused by a large number of things, theoretically. Here is what I know:

• When viewing on twitch.tv with quality 360p or higher, the video feed will usually (95%) become colorful static within 1 minute or less. When this happens, the video feed does not ever recover until page is refreshed or quality is changed. (I know a bit about video encoding, so this seems extremely odd to me, if it were due to a networking thing that lost some packets, a full-image frame should come alone sooner or later and fix things, but that never seems to happen)
• The video feed is far less likely to become corrupted when viewing at 160p, but can still happen.
• The ads may become corrupted in the same way that the main video feed can.
• When the feed is corrupted, the rest of the Twitch interface (pause/play, volume, quality select) is extremely laggy.
• When the feed is corrupted, if I pause the stream, sometimes the paused corrupted image is not completely stationary! There will be flickering in small portions of the image, looking similar to texture fighting in 3d rendering, flickering between two equally-but-differently corrupted versions of the image
• The issue never appears when using Chrome to watch twitch.tv. This is what makes me think Firefox is the culprit, not Twitch or networking or graphics drivers.
• Disabling my browser addons does not help.
• Private browsing window does not help.
• Clearing my browser cache does not help.
• I have had the issue happen on Youtube exactly once in 2 weeks, not sure if that's related or not, I think it was a normal "lost some network traffic but fixed itself the next time a full frame was received" thing.
• Video live streams on Youtube don't get corrupted the way they do on Twitch.

Can someone please give me advice for how to fix this? Has anyone seen anything like this before? Is there a way for me to get deeper under the hood of either Twitch or Firefox and more closely debug the video stream when it fails?

I had a issue with my Dell laptop, when it was resolved It had deleted Firefox. They created a new one, but the bookmarks are gone. I have looked at the information on recovering Bookmarks, but still cannot recover my bookmarks.

Can I get help on this issue?

Thanks,

Riley

Hi Win10 PC fully up to date. Changed my printer from a Xerox to an HP laser. In the control panel, set the HP as the default printer. MS Office prints on the HP without prompting. Firefox (134.0.2) always defaults to the Xerox. The HP is available in the drop down box. Restarting the PC or reloading Firefox makes no difference, Firefox always defaults to the (non existent) Xerox. MS Edge defaults to the HP. Any ideas? Regards - Andrew
