Firefox Community Forum

I manually clear all youtube cookies. I have these youtube exceptions. After going to youtube, then checking "Manage Cookies and Site Data" I still see Firefox saved a youtube cookie.

Thank you

When Firefox updated I only created a default profile and could not or did not import bookmarks. They seem lost now. I was offered to import from other browsers like Edge but did not see any way to import from my previous Firefox version. I am unable to find any automatic backups in bookmarkbackups folder.

I accidentally deleted all cookies in my browser using an extension and want to restore them to how they were one day ago, but I can't find the restore button anywhere. I found an article on https://support.mozilla.org/en-US/kb/firefox-backup , but I don't have the buttons mentioned in the article. I don't have a “Restore your data” section or a “Choose backup file” button, and when I click on the link about:restore, I get the response “Hmm. That address doesn't look right.”

PLEASE HELP

I have around 20 tabs in my firefox browser about tarding they all keep refreshing at the background when i am using firefox,its causing my Laptop battery drainage

I've just switched to Fedora 43 KDE plasma from Windows. On Windows, everything was totally find with videos on Firefox. After migration I kept having an error message "The media playback was aborted due to a corruption problem or because the media used features your browser did not support." not only on one site (else it could have been the site). After searching for solution here and on the Net, I found out that it's not related to Fedora but to Firefox when using Radeon RX7700XT on Linux (idem with several distros). And indeed, when installing other browser and testing them there was no problem, even with LibreWolf. So can you please take action as I like Firefox and I would not like to have to move everything to an other browser. And it seems that this problem has been around for at least two years ... which you should be ashamed of.

I have Firefox installed and pinned to the taskbar. When I click it, it immediately goes to a download Firefox page instead of opening. I then open another tab to get into g mail or anything else. I can then close the download tab and continue. This is most annoying. I tried uninstalling and reinstalling which works but then lost all bookmarks and the answer there was to go to old Firefox and restore, which I did and that worked , however, the download page came with as well and this time in a different more colorful version that is quite long.

This appears to be a new "feature" that is absolutely insanely stupid.

There are websites that use a phone number as a user ID and now, instead of that number being remembered by Firefox as a user ID, Firefox now inserts a list of EVERY possible phone number you've ever typed, for you to chose from. The irony in my case being that the phone number in question that was being used as a user ID, is NOT in the list.....

Anyone know how to turn it off? Thanks - Brett

Up until a few days ago I was able to preview yahoo mail attachments (e.g. PDFs) before downloading them. I don't know what may have changed, but I don't recall doing anything on my end. Any suggestions or advice on what settings I should consider changing greatly appreciated. M

I'm using Kubuntu 24.04. I saw it more than once. Firefox is frozen, no WiFi for example, and I have to kill it via terminal. After that it is not possible to retrieve the session (3 or 4 tab groups plus ~20 tabs)

thank you for any help.

if I had 30 bookmarks, there was no problem to sort all by name, if I´ve had 40 bookmarks I must sort it 3 times but then it works. But now I have more than 50 bookmarks and I testet it every update but it dosen´t work, why ?

I've just discovered that a lot of files I've downloaded in the last few months have the original file date instead of the download date. This has created total chaos and confusion with my organization as I have no idea when I did anything!

I presume Firefox has changed something. But why? When? What files does it affect? How do I change it back?

And why weren't we told about this huge change? After over 30 years downloading files from the web, it's become second nature that downloads always take the download date. A monumental change like this needs to be clearly signposted or it's going to create chaos with people's file systems and organization.

Update: On reflection, I think this is a Windows 10 bug, rather than a Firefox issue, so perhaps this thread should be deleted? I looked at the properties of the files in question and discovered that all three dates DO match the download date. The problem seems to be that WINDOWS ITSELF is displaying EXIF data dates instead of modified date. I only recently started using Windows 10 and this would seem to be a Windows 10 bug.

Hi Firefox support,

I’m experiencing a persistent issue with Google Fonts (.woff2) on Windows 10. Only on some but not all pages whoch are using Google Font woff2: Fonts display correctly after starting Firefox, but as soon as I reload the pages with for the first time, they appear corrupted and remain broken. Private Browsing mode renders the fonts correctly, and Chrome does not have this problem.

Below is a detailed list of everything I’ve tried with ChatGPT so far to troubleshoot the issue.

(OS: latest Windows 10)

Browser: Firefox (freshly installed, no sync)

Behavior:

Example site: https://www.linguee.de/

Steps already attempted:

Disabled all extensions

Tested in Firefox Safe Mode / Troubleshoot Mode

Created a new Firefox profile

Fresh Firefox installation without signing in

Deleted all relevant caches:

%LOCALAPPDATA%\Mozilla\Firefox\Profiles\<profile>\cache2

%LOCALAPPDATA%\Mozilla\Firefox\Profiles\<profile>\storage

%APPDATA%\Mozilla\Firefox\Profiles\<profile>\startupCache

%LOCALAPPDATA%\Mozilla\

Verified / adjusted Firefox config in about:config:

browser.display.use_document_fonts = 1

gfx.webrender.all = false

WebRender running in WebRender (Software) mode

privacy.resistFingerprinting = false

browser.cache.disk.enable = false

network.http.rcwn.enabled = false

accessibility.force_disabled = 1

Disabled hardware acceleration for testing

Tested DirectWrite / Direct3D settings

Recalibrated ClearType

Ran sfc /scannow to repair system fonts

Temporarily disabled antivirus / web protection

Tested behavior in private mode versus normal mode

Observed that hard reload (Ctrl + F5) does not fix fonts

Noted that only .woff2 (Google Fonts) are affected; system fonts render normally

Summary:

Issue is not caused by extensions, profile, cache, or a fresh install

Private Browsing works → problem is related to persistent normal-mode caching or rendering

Only occurs in normal windows, consistently reproducible after first reload

Problem seems specific to .woff2 font handling and Firefox’s rendering pipeline on Windows 10

While transferring data from the old profile manager system to the new one, I accidentally created one more profile than I needed. I have tried to delete the extra profile on multiple occasions, it won't go away. I have attempted to delete it through the profile management ui, and I went into the files and delete the associated data. On both occasions, the profile remained in the UI. I am unable to edit anything about the profile either. Is there anything I can do to resolve this annoyance?
