Firefox Community Forum

Dear Sir/Madam,

I have recently found some sites that do not open in Firefox, however, in Chrome everyhing is fine. This was one of them: https://sciendo.com/article/10.2478/jdis-2025-0002

The other one was a login page for an Admin site - that is not suitable for testing, since it contains confidential data.

Could you please check it?

Thanks, Krisztina Kőrösi

Youtube seem to be having problems with video decoding, previous frames seem to be displayed from time to time. for ex, this video: https://www.youtube.com/watch?v=dFhzMEnCEhY

The same profile works on Firefox 134.0b8 (64-bit) without problems, but not on nightly. If I just disable `media.hardware-video-decoding.enabled` and restart, then the problem goes away on Nightly.

Enabling/Disabling my user customizations don't seem to affect it. Enabling/Disabling addons don't affect it. Using a new empty profile also doesn't affect it, the problem persists. I tried deleting "gmp-widevinecdm" folder and redownloading it, still didn't solve the problem.

I seems to be some sort of regression, it used to work before a couple of days ago. Please fix, I hope the information I provided helps, as I like having hardware acceleration.

I also tried to update the display driver. nVidia Driver: 31.0.15.5176 now 32.0.15.6636

After new update (135.0a1) my youtube vids starts with audio but NO actual video. Also it timeline constantly extends (like when you move cursor to timeline is extends verticaly and get more light color) and back to grey state.

I tried remove all addons, clear cookies and private windows. Also previewr of video rly buggy and just spams images(?)

For some reason i dont understand when i play a music in youtube music its kinda like a dark screen but it has this weird thing that if i switch tab and then come back is like a part of the other page, example shown.

it doesnt work even in private mode but it works with troublesthooting mode, even if i disable plugins and stuff it just doesnt work

Is this something to be concerned about with future sites, or is this an unfortunate, isolated incident? One of my local utility companies is not going to be supporting the use of Firefox on their website any longer. Has anyone else seen anything like this on other sites, or has this been brought up elsewhere? Frankly I find it outrageous and is forcing me and others to use Chromium based browsers (aside from Safari which I don't use).

• I emailed the company asking for an explanation, and I'm awaiting a reply.

I would share the URL for others to email and help press the company on the issue, but wasn't sure of the guidelines of the forum or if that was appropriate. I'm just irritated and venting sorry =/

Firefox auto updated when I opened it today. Then when it opened, all that was on the screen was the menu (file edit view history bookmarks tools help), the "search or enter address" box, and in the upper right hand corner the words "private browsing" with the purple circle and eye eyeglasses icon. That's all. I have tried looking at my profile. It seems to still be there. This seems to be a problem with the Firefox software itself. I have re-downloaded the software three times, the last time I uninstalled Firefox from my laptop and totally reinstalled. Every time I get the same results. This almost blank screen. Let me be clear. There is no purple background, there is no Firefox icon, there are no tabs, there is no customized menu bar, there is no search box in the middle of the screen. I'm working on a Windows 10 laptop 64 bit. Please don't tell me to upgrade the Windows 11, the laptop won't take Windows 11. I get the same window whether I open the regular fire fox or the private browsing Firefox.

I had a background image for the new tab page that has suddenly stopped working, it just displays a white screen. I clicked the 'reset to default' button next to 'Wallpapers' on the new tab page to try to fix the problem but nothing happens. No wallpapers show up under that section either where it used to be when it was working. I've restarted Firefox and the same thing happens. I have not enabled any third party CSS wallpaper.

Apart from that, everything else is working as it should. I'm sort of a computer-idiot so if anyone could please use layman's terms it would be very much appreciated!

I could not remember my pw today when trying to get bookmarks back on this computer, so reset, thinking I would otherwise be locked out --now I'm not seeing an option to sync bookmarks. I'd love to get back these bookmarks--a treasure trove of resources gathered over 9 years. Any help greatly appreciated!

When I'm clicking "Copy Link Without Site Tracking" on Facebook, I'm getting a very long link like: [0=AZXHU5Fm3iETylzElY4qHRw27uWnI_VbYwCYYbj6x6BPjGaj_yfVTLR8fIvGILOGciQm0_XpeFu6uqxnV147PjmDPArCU4fCaydKmZ6_0BAp3j7mfUtGQhNPJQKsjPAK1sN0M7CjPgKHhIlL7_Mb2poXSVjQwF_nMhqHO7Xc_XTtdLQw9hxaPV5qUcKm8rbrWus&__tn__=%2CO%2CP-R https://www.facebook.com/PilsetaCilvekiem/posts/pfbid0EqFQ5TwTkHeowowTc7ArY8T7ATCjxXvWiUzXJeDxCjCcQHFwt4h8PK9eJaEiaYiml?__cft__[0]=AZXHU5Fm3iETylzElY4qHRw27uWnI_VbYwCYYbj6x6BPjGaj_yfVTLR8fIvGILOGciQm0_XpeFu6uqxnV147PjmDPArCU4fCaydKmZ6_0BAp3j7mfUtGQhNPJQKsjPAK1sN0M7CjPgKHhIlL7_Mb2poXSVjQwF_nMhqHO7Xc_XTtdLQw9hxaPV5qUcKm8rbrWus&__tn__=%2CO%2CP-R].

Would it be possible to remove URL parameters "__cft__[0]" and "__tn__"? Because https://www.facebook.com/PilsetaCilvekiem/posts/pfbid0EqFQ5TwTkHeowowTc7ArY8T7ATCjxXvWiUzXJeDxCjCcQHFwt4h8PK9eJaEiaYiml opens the same post.

Team, I am a longtime user and supporter of FF. I can't tell you how much I love the the layout of Firefox on Windows in v. 133 with the vertical tabs. Just as important is the fantastic, new font rendering. Thank you so much. I used to make multiple adjustments to the font in about:config when I installed FF on Windows. Now, the fonts look fantastic out of the box. Great job, team!

I go through the process of signing into Firefox Sync, it sends the confirmation e-mail and i copy paste the code in, then it takes me to the mozilla accounts page and shows me all the data about my account, but when i click on sync under settings, it says "account disconnected" if i click "sign in" the process repeats with the end result being "account disconnected"

I've been using and enjoying Firefox for years on my various Windows machines. I've just purchased a Ubuntu Linux Thinkpad and have installed and used Firefox for a few days. It's generally working well except at start-up. Apparently it tries but can't restore the previous session, even though I have not selected "Open previous windows and tabs" ??

I am using lastest version on Windows and Linux (133.0) but I did notice the settings/options are a bit different in Linux, but I would just like to set my Linux FF to do same as Windows FF on startup, that is just two open tabs: - Gmail opened as a pinned tab. - Google Search as the open tab with focus I've attached a snip of the relevant section in General Settings How do I set this up in Linux? Thanks in advance
