Firefox Support Forum

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

Starting Friday April 19, I have been experiencing constant very brief internet outages/reconnections while using Facebook on the desktop. The outages do not occur anywhere else on the internet...and do not occur on other browsers. I prefer to use Firefox. I am using Windows 11.

Issue description: Similar as https://support.mozilla.org/en-US/questions/1294366 But I'm not using USB wireless receiver, I'm using wired network adapter for connection

I've been using the Firefox browser, and recently when downloading files with Firefox, sometimes it prompts: .part could not be saved, because the source file could not be read. # see image #1 I'm trying to download file to disk D. But the fail tips is download .part file to disk C. Maybe firefox is using some file cache policy which I don't know. I also checked both two location, my account have read/write access.

I can try to resume the download, and the download progress will increase, but about half a second later it will fail again. If the file is small and my internet speed is fast enough, after several attempts the file will eventually download successfully. # see image #2 I have tried using "private window" or enter "about:profiles" to create/use a new and clean profile, but the issue still persists. # see image #3 I tried using other download tools like "Internet Download Manager", and the download was successful. It's ok for use chrome to download the same file to same disk location. The problem recently emerged, it didn't exist before. At least a month ago, the same computer didn't have this issue. I'm not using parental controls.

Enivronment: OS: Windows 10 professional 22H2 Firefox version: "124.0.2 (64 位)", auto update is enabled, it should be the newest version. security software: windows defender

Firefox Version: 124.0.2 (64 bit) Windows Version: Windows 10 LTSC 2019 (Version 1809)

When I right click the taskbar and press close Firefox, here comes the interface just as the screenshot uploaded. The blue close button doesn't response no matter how I click it and the Firefox's taskbar is flashing yellow. This bug only occurs on the first window of Firefox and only when user right click the taskbar.

It has been a long time for me wishing that some updates would be released soon to fix this issue, while noting happens. Or this bug is only for me?

Currently, I use Firefox version: 116.0.2 or v117.0 on Ubuntu 20.04.6 LTS.

I encountered a phenomenon like this:

• When I logged in to the application, in the tab I was working on, the Firefox session memory was lost (don't open new tabs)

Steps: 1. Login to the application 2. Operate on the screen 3. Navigate to other URLs, but still on this tab 4. Session storage was lost

What is the cause of this phenomenon? How can I fix it?

Prior to about a month ago, downloading worked as expected: - click a link - the save to... dialog opened - choose the folder - the download is off and running

No more. For about the past month - click a link - wait for a long time with FF frozen - the a wheel starts rotating - after a full minute (or more) the save dialog appears.

Something has been broken in the mad-dash to push updates. It's fine for browsing, but the, you need to download. At that point you wish you were using a different browser (any other browser, in fact) since FF is the only oe that has this problem. Downloading works fine in a 8 chromium browsers that I have and in the 5 FF clones (like Waterfox)

It's just FF that's broken. I can no longer afford to set it as default because of this. The others are not perfect (WF won't activate Pocket, foe example) but downloading promptly is critical.

Hello,

I need your help because i can't find solution to problem. On my macbooks air m1 i experience a very annoying thing: Often while i'm scrolling on websites smooth scroll animation get choppy/sluggish for few moments and lagging. It's like animation is FPS dropping during the scroll. I tried lot of things on both device:

- tried without extensions - created new profiles - use without syncing data - disabling hardware acceleration (gets worst) - disable smooth scroll in settings (get worst) - completely remove firefox with AppCleaner and reinstall it - Reinstall macOS and just install firefox alone. I tried latest Ventura and Sonoma

I don't have clue why this happening but ruin user experience very bad. With Safari everything is fine and smooth. On my wife's device (macbook air m3) have same issue.

Do you have any idea how can i fix it?

latest 124.0.2 causing severe problems, it will near instantly bloat to fill all RAM and SWAP even in safe mode causes system load over 24! only solution is to reboot very problematic on for ex: https://epg.pw/xmltv/epg_CA.xml hard to get a screencap since system is nearly totally unresponsive. RAM is ok SSD is ok MX Linux is ok

Issue: The "Recommended stories" setting for the new tab default home page periodically re-enables itself.

Version Info: Firefox 124.0.1 (64-bit) OS: Linux Mint 21.1 Cinnamon

Additional Information:

• I do not use pocket, at all
• All settings that I can find related to pocket are disabled
• I do use Firefox Sync, however the other device (124.0.1 (64-bit) on pop_os!) does not have this issue
• Does not correlate to version updates (Mint has automatic updates disabled in policies)
• Does not occur after a simple restart

I am tired of disabling this setting and having it return seemingly randomly. I have no interest in these stories, and consider them spam.

Please assist me in determining why this is happening on this device and how we can go about preventing it going forward.

Thanks, Steven

Hello Good People,

I noticed that the snap version of Firefox had a lag issue when typing into input field. For example, when composing an email and wanting to use backspace to quickly delete a misspelled word, then backspace works slowly, stuttering and jittering. If I hold down a key in the input field it also lays the character down in a stuttery, slow way.

I tried reinstalling the system and that solved the issue. But it has returned again. Maybe it was an update. I also installed WINE and waybridge to get some windows plugins to work on my DAW. I don't know if that has affected it.

I also tried removing the snap version and installing firefox using the terminal but the problem persisted.

It's an annoying problem. Any advice appreciated.

I recently have gotten a message about manually updating Firefox on my Windows 11 system. Even after I updated, I then I started getting the same message and also "Failed to check for updates" in the Firefox "about" box and settings page.

I even went about uninstalling Firefox and reinstalling it while deleting the Firefox Program Files and user AppData directories. I also checked for a Windows Firewall entry for the program.

Is there something in another directory or registry setting I need to delete or change? Or does Firefox use a different program for updating that needs a firewall rule?

Thanks for any help.

I have used Firefox as my browser for many years and lately my emails won't open or if they do it is very slow sometimes and won't allow me to delete emails. Not sure why this is happening and I asked by email provider and they told me to follow some instructions about fining the menu button of Firefox which I couldn't find then he gave me a link and I tried to follow but was unable to make any progress. I use spectrum email services

I'm using MacOS Sonoma 14.4.1 and recently, my browser has started freezing up for several minutes. It seems that the culprit is the "fontd" process because when I open Activity Manager that process spikes to %50 to %80 CPU usage. Killing the process does nothing and quitting out of Firefox does nothing either. I made sure Firefox is fully updated, but still nothing. I'm not sure whether it's a problem with my Macbook Pro's fonts or if it's a problem with Firefox, but I'd like my browser to be reliable.

Does anyone know what might be causing this issue or what I can do to resolve it?

My Firefox recently updated to version 124.0.2. Afterwards my taskbar shortcut broke, so I pinned a new one manually (right-clicked Firefox in start menu > open file location.) When I opened Firefox it had reset the primary profile to be default, so I changed it back to my BetterFox profile. Since then I've run into several oddities, such as Firefox crashing when it's running in the background, getting an error saying "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window," when I try to open it, invisible shortcuts in my taskbar(see image) and my bookmark visibility resetting from always to only in new tab every time I start up Firefox. Please help me.

Hi, I can't read some DRM protected media anymore (Prime video, Spotify) in Firefox in Windows10.

The error I get say that firefox doesn't have Widevine installed (but it does).

I can read the content with other browsers (Brave) so the problem is not Windows Media Foundation i guess?

What I already tried:

-untoggling/toggling Widevine in plugins

-reinstalling firefox and using a new profile

-using Firefox Nightly

-removing the drm folder from the profile and relaunching firefox

Output of the console:
