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

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.

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

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 =/

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 updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

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

Hi All,

I need open local exists files

file:///.../index_details.rst or file:///.../index_details.txt in my default system editor.

This has worked pretty well last in version 127. (https://ftp.mozilla.org/pub/firefox/releases/127.0/linux-x86_64/en-US/)

But after v127 Firefox always opens files directly (see screen). I can't find any settings to change this behavior. Something has been changed.

I keep back the firefox upgrade so long it was posible for me but 127 is now old and i use the last version 133.0-1.

I'm using Linux (Debian).

Thanks

I am having issues signing in to the playstation store using firefox. It works on edge (although I have the same issue in ungoogled chromium). I have tried refreshing but that didn't work. I uninstalled it and deleted all mozilla folders in appdata, then tried again without signing in to my mozilla account on a fresh install but i'm still having the issue. It might be a windows configuration issue because I don't see why this would work on edge but not on firefox. I've tried disabling all cookie and tracking protection features but I still have the same issue.

My system memory is reading at 57% right now in task manager, that the vast majority of that is being used by Firefox.

Why?

Normally, this would be called a flaw in the program, not the user, as all I have done in regards to settings is "keep tabs previous open when re-opening Firefox" and "Do not automatically update" because Firefox took it upon itself to not re-open my previous tabs on the last update.

Why is this program eating up all of that memory? I have "Firefox (15)" in Task manager under "Apps" and then 13 more instances of Firefox in "Backround Processes"

Wtf?

Well looks like they did it to us again. My tabs are back on top again and need to put them below where I am a lot of other users like our tabs!

Update: Codes working fine now for 133.0

Recently, every time I turn on email on Yahoo, I get a noisy notification when each email is received. I do not want or like it. It is annoying. How can I turn off the notifications?

Youtube's side panel on the left does not load at all, the videos on the homepage do but none of them can be played. When I play a video the website doesn't load that either. I only get an hourglass icon on the tab. Image attached.

Google search results don't show up immediately, despite being loaded. Only after about 7 seconds. Image attached.

I don't have this issue on other browsers. It has only started occurring 3 days ago, I'm clueless as to what the cause may be.

Solutions I have tried: 1. Restarting my PC. 2. Turning off all my extensions. 3. Running Firefox in troubleshoot mode. 4. Refreshing Firefox.

Several weeks ago, I was attempting to upgrade from Windows 10 to Windows 11. In the process, I deleted Firefox (using Revo Uninstaller) and then reinstalled it, downloading it from the Mozilla website. Unfortunately, it didn’t run, giving me, at different attempts, different error messages. In the time since then, I have read many suggestions from many different websites and I have tried some of these suggestions, all with no success – until today. I have just completed the suggestions made on https://support.mozilla.org/en-US/questions/1327628 and Firefox is now back, working. I am happy and grateful, but not finished. None of my personal data came with the currently functioning version of Firefox. Since the re-emergence of Firefox, I have been reading several websites dealing with copy, backup and restore of my Firefox profile. Right now, the path C:\Users\rsuth\AppData\Roaming\Mozilla\Firefox\Profiles\ shows 5 folders: Two of the folders show 11/11/24 as the date modified (probably the date of the download from Mozilla). The folder 0dppjrfa.default contains one file, times.json, dated 8/11/2020. The other folder, ru82tlj5.default-release, has 97 items, most dated 11/11/2024. The remaining three folders are all dated 12/2/24 (today, as I write this). One folder’s name ends .default, the second name ends .default-release, and the third name ends .default-release-thirteen digits. The question that I am asking here is what do I do next to, hopefully, bring back the personal date I had with Firefox before my updating to Windows 11. Should I delete the folders dated 12/2/24? What, if anything, is the significance of the folder whose name ends in 13 digits? I’m hoping someone will be able to tell me how to fix these Firefox problems. And if I can, then I hope to be able to do something similar to help me bring back Thunderbird as well. Thunderbird became unfunctioning at the same time as Firefox. Thank you.

Hi. I'm trying to troubleshoot failure to resume a download in Firefox and I want to see the HTTP headers just like in Network Tab of Dev Tools, but I can't find how to open Network Tab from the "Downloads" list. Is it even possible?
