Firefox Community Forum

Over the past day or two, I've seen firefox incorrectly render fonts on a couple of websites. So far, I've only noticed two websites effected: quotientapp.com and xero.com (not the actual landing page, but rather the login page and other pages available after login https://login.xero.com/identity/user/login). This problem may extend deeper but these are the only places I've found them.

At first I thought my eyes were playing tricks on me but nope, something definitely not right. No new addons have been installed on my system. I've also deleted all local storage / cookies (via the Inspector) for these sites thinking it must be some caching issue - but no, it's still doing it.

Inspecting the font-family shows the issue (this is from the page https://go.quotientapp.com/sign-in) - have attached the images below of what I see.

I do use uBlock, but it is disengaged on Quotient and Xero (these are work related sites, they show no ads). Other add-ons I have installed include Bitwarden, Dark Reader, Firefox Multi-Account Containers and Reddit enhancement suite. I've ensured all add-ons are up to date as of this posting.

FWIW I do allow all the extensions above (with the exception of Firefox Containers which I don't allow) in private mode.

Any insights on how to get to the bottom of this?

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

Hi, I am seeing issues with autoscrolling in 119.0. In Rundeck for example you can "follow" the output of playbooks that are running so you can dynamically see the log as it is written. The autoscrolling in this field has stopped working. When manually scrolling in the field, more messages appear but the autoscrolling is no longer functional. I have also seen it on other places, though I don't have remember good examples to add, so I don't believe it is Rundeck causing the issue--we also haven't updated rundeck recently in our environment, so it shouldn't have changed since before 119.0 was released. Let me know if there is more information I can provide to diagnose the issue.

Hello, since today I am experiencing instant crash on start up. It was perfectly fine yesterday (10 hours ago). Even attempting to open safe mode when offered also instant crash. Firefox is currently unuseable.

I believe the recent 124.0.1 is the issue ? Can this be confirmed, where can I check if this issue is widespread & the ETA to an eventual fix ?

Firefox version: 119.0 (64-bit) OS: Windows 10 Home 64-bit

Hello,

Whenever I open a local HTML file, Firefox tab will crash. This happens if the HTML file size is big (>4MB), smaller file doesn't crash.

I've tried opening the file on Chrome, it doesn't crash and open just fine. So it seems like this is a bug with Firefox.

I've uploaded the HTML file if anyone wants to test: https://www.mediafire.com/file/ipmu7ugrd2vvelr/LICENSES.chromium.html.zip/file

Thanks

Online forms don't appear in Firefox (Windows 10 PC), but do appear correctly using Edge or Chrome. This has been happening for quite some time. I have o switch to Edge or Chrome to see the fields to fill in on online forms.

How can I turn this message off? Some sites I visit give me that message, it shows up when I'm typing a reply to something which pushes the page lower and fouls up my ability to keep typing, then if goes away, comes back, goes away ... I just want to kill the message entirely. I'm not worried about speed, there's nothing to fix, I just want the message gone.

When I sign in to a website I check the box saying 'remember this computer' but FF doesn't seem to allow this. I have to go thru the security login every single time, like when signing in to a google account. It works on Chrome but not FF.

This may be related: sometimes the page displayed on FF doesn't function as it should. Example: I was using Quickbooks online and when I clicked the HELP button nothing happened. I thought it was an Intuit problem until I used Chrome and found the HELP button worked.

thanks

Hello ;-)

If i try to watch amazon prime video, Firefox crashes the whole system (no further action possible). Taskmanager does nothing, CPU is on 100%. Badly there is no crash report or Firefox log - maybe because the whole system is freezing completely. Widevine has been loaded correctly.

I tried Opera and there is no problem. I tried also 4 several PCs - always the same. Firefox crashes the whole system, Opera is working without problems. I didn´t try Edge or Chrome - i didn´t want to "rubbish" my system ;-)

Sure, i could use Opera, but ... my favorite is Firefox for all the years ;-) The failure appears with version 1.11 - earlier versions had no problem. I´ve only installed privacy badger and no other plugin or extension. Also DRM and widevine is activated. Reinstalling (after registry and install cleanup) didn´t solve the problem. And, yes, i have all recent updates on Windows 10, graphic card driver and Firefox.

The support of Amazon: "no idea" ;-(

Any suggestions ? ;-)

Best regards

Firefox use 100% of my cpu and drops frames when playing 8k video (gpu acceleration setting is turned on). Chrome instead have no frame drops and does not use 100% of the cpu.

I tried to google it and use some solution, but no effect in my case.

hardware: cpu: ryzen 5600x gpu: rtx 4070 ram: 32 gb monitor: LC27 JG50QQIXCI (qhd 16:9 144hz)

PS: 1st picture firefox, 2nd chrome.

So I have a following problem

FF 124.0.1 Windows 10 N edition Installed media feature pack

When trying to play twitch video it shows error 4000 and when trying to play stream from youtube it shows that your browser can't play this video.

Problem is that FF was able to do it like 6 moths-year ago (not really watching stream videos)

was trying to reinstal media feature pack, firefox, chcecknig nighgtly build but without sucess and have no clue what can do more

For the last several days (as of 12/20/2023) I have had issues with playback on sites including Netflix, Amazon Prime, and Dropout.tv (not YouTube). Error messages indicate that my browser is unsupported and I need the newest version of Firefox, but my browser is completely up-to-date. Pausing my adblocker on these sites does nothing to correct the issue, nor does restarting the browser or my computer.

Dear reader,

Websites like Netflix and websites banks ask for an update of FF,although I have the latest, 121.0.1 Netflix doesn't allow me to enter the website (see screendump) The ASN-bank asks for an update but I can work around it (see screendump) Screendumps are in Dutch, they text is about asking for an update.

Can you help me out to fix this?

Thanks in advance. Frans

Hi.

Ever since I upgraded to version 123.0.1, I am constantly getting slowness on websites stuck in "Performing a TLS handshake..." Eventually the websites load, but it's frustrating. I have read about the various solutions and have tried the following: Disabled IPV6 Refreshed Firefox Reloaded Firefox Disabled and removed all extensions Restart in safe mode Create new profile

This was not happening in version 122 and before. Microsoft Edge does not have this problem, but I prefer to use Firefox. I am running Windows 11 Pro. Any ideas?

Thanks

I'm hoping someone can help with a conundrum.

A few years ago, whenever I first started Firefox--whether I had just started up my computer or had exited Firefox and opened it back up--it would take several minutes for Firefox to load any website (Google, Amazon, weather.com--anything). Once the first site loaded, it would load subsequent sites normally. Interestingly, it was only my default profile that was affected; if I used another profile or created a new one, websites would load within seconds of my starting Firefox.

I finally broke down and created a new default profile, imported my history/bookmarks/etc., reinstalled extensions, adjusted settings, etc. The new profile behaved nicely, loading the first website within a few seconds of Firefox starting. But over time, the load time has gradually increased to the point where it is now behaving just like the old profile: I load Firefox, I try to go to any website, and it takes several minutes for it to load.

Any ideas what's happening/what's the problem? Hoping someone out there has some wisdom and can help troubleshoot. Thanks!

Hi I am the admin site owner of the above site on th site we have a widget that lets us monitor who is in our teamspeak server from the home page this was working great until I and other members updated to firefox 121.0.1. 2 days ago, now we get this message in the widget frame insted.

Firefox Can’t Open This Page To protect your security, server.nitrado.net will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

After an update of ubuntu 22 on my computer, Firefox does not render properly (see the screenshot of my desktop). I have tried to reinstall it but it continues to happen. All the other programs works fine, it is only firefox.

My system is: Ubuntu 22.04.2 LTS Processor: AMD Rysen 5 3600 6 core procesor x 12 Graphics: AMD Radeon rx 5500 tx

Thanks.

I added a screenshot of youtube having flickering while video is being played, it is a bit hard to see but there is a slightly brighter stripe on the grey background and picture cant depict flickering; it starts immediately after video is started and stops after 3-4 sec after video is paused, like there is some background activity behind youtube foreground. I understand my comp is weak (Intel Iris Graphics 550 1536 MB 8 GB, 2133 MHz LPDDR3), but not that much, please help
