Firefox Support Forum

Hi Guys! Huge fan of Firefox since the early 2000s when I first learned about it. Way more secure, efficient, and lighter than any other browser (IE, Chrome, and now Edge). Firefox is my first download on every new device and my go to even on my iPad.

I've been getting this error message lately and I don't know what to make of it. My saved tabs are working normally (email, work, streaming entertainment). This automatically comes out on ever new start / re-start (Firefox is my default) on separate tab but I am not opening any new website. It's been 2-3 days. At first I didn't mind it but its consistently happening and not just a one time thing. I already cleared my cache data. I've also ran a scan and it's come up clean (I have a paid BitDefender subscription). It's also not the local ip of my machine.

So any help would be great as I really don't want to leak any personal data or have any viruses.

Thank you for your time!

Hello, have been scratching my head for a while on this one. Have a freshly setup install of Debian 12, using Sway (wayland) as my Window Manager. I am really struggling with slowness in Firefox, page loads take easily 15 seconds whereas loading the exact same page in another window at the same time with Chromium Debian build has near instantaneous load times. I've tried the following troubleshooting steps: - Created a new firefox profile - Tried "Troubleshooting Mode" in Firefox - Disabled ipv6 in firefox about:config and in Debian - Tried different DNS servers - Tried different non-debian specific builds of Firefox - Tried Firefox Beta and Firefox Nightly for Debian

None of these steps made any difference, and Chromium has continued to be significantly faster. Am really stuck here and would love to get to the bottom of this as Firefox is the only browser that works with a HiDPI display in Sway without blurryness. Happy to provide any and all diagnostics and reports that are needed. Thanks in advance!

EDIT: It seems to be some kind of networking issue, using a VPN solves it. But still doesn't explain why Chromium would behave differently.

Hello. I use youtube website as music player quite often (without premium) and play my favorite list of songs. Meantime, when Google started meddling with youtube due to their new offer as youtube premium I met two most annoying issues like "are You still watching" dialog and the behaviour where youtube just cleared "repeat list" function without my consent. Both issues was resolved with java scriplets I took from community.

Now I run into third issue but not sure how to diagnose it. If Firefox is in the background, or tab with youtube has no focus the playlists stops from time to time. The moment it stops is when next video should start playing. When browsing on different tab, I can see on Youtube tab that title of the video has changed (to the next video) and even the song started (for 1-2 seconds) then video pauses and word "playing" disappears from tab (normally there should be title on tab and "playing" word under title). It is not "are You still watching" dialog issue because if I move mouse cursor on youtube tab (even without setting focus on it) the player will continue - till next song.

The issue doesn't appear if youtube tab is active. I can't use developer tools in firefox because can't debugging website when tab of the site is not active (at least I don't know how). I tried to find solution with community but with no success. I allowed youtube to play video and sound always without exception in firefox preferences but it is not the solution.

Any tips?

• Bulleted list itemI understand! You're asking how to use Mozilla Firefox or Safari. Here are some basic steps to get you started:

Mozilla Firefox:

1. Download and install Firefox from the official website. 2. Open Firefox and set your default search engine and homepage. 3. Use the address bar to enter URLs or search queries. 4. Explore the toolbar for bookmarks, history, and extensions. 5. Customize Firefox with themes, add-ons, and settings.

Safari:

1. Open Safari on your Apple device (it comes pre-installed). 2. Use the address bar to enter URLs or search queries. 3. Explore the toolbar for bookmarks, history, and sharing options. 4. Customize Safari with extensions, settings, and privacy features. 5. Use iCloud to sync bookmarks and history across devices.

If you have specific questions or need further assistance, feel free to ask!

I've had an ongoing issue with Firefox now for several months since upgrading to windows 11. When I try to copy text, or images, url's or anything really that is supposed to go to the clipboard, it copies a blank text with no data instead. I can copy text and images from other programs and even paste them into text fields on Firefox but I can't copy from Firefox to anything else and it's frustrating.

I recently got forced into upgrading Outlook in windows and hated it so I started using Thunderbird and surprisingly, I have the exact same issue there as well.

I have tried: Running Firefox in safe mode (Shift + Left Click) Resetting Firefox Switching Back to default themes Disabling hardware acceleration Updating to the latest Beta Build (v126) Running Firefox Developer edition

I really want to get this fixed and working, I don't want to have to switch to another browser =/.

Due to repeated issues over a week, I uninstalled Firefox days ago. Tried to Reinstall it repeatedly on same device several times. It was working before..BUT it keeps showing its downloaded on Settings but Firefox download page keeps showing "DOWNLOAD" Tried several times. Not my computer. Nothing works to resolve it.. Windows 11..

I am trying to log on to my account at SketchUp. At the login page i hit get started and a black page come up except in the top left corner is typed "Firefox not responding" the page hangs a few moments then it takes me back to SketchUp login. I have not had any recent updates done or required since last logged in and that was yesterday all worked well.

I'm using Firefox 124.0.2 (64 bit) on Windows, and every few days I get the error about using an older version of Firefox, with Exit or Create New Profile options. I then run "firefox -allow-downgrade" from the command prompt and everything works fine... for a few days, when it happens all over again. This only started happening a couple of weeks ago, but it's getting really annoying. How do I stop it (short of using something like Waterfox or Brave).

Firefox 125.0.2 on Mac

When I press shift+cmd+D to bookmark all open tabs, instead of the links being saved to the designated folder, they are all saved to "Bookmarks Menu". The designated folder itself also appears with these links but it itself is empty.

I would expect shift+cmd+D to bookmark all links in the folder and the folder to appear in "Bookmarks Menu". This is what use to happen ages ago. I'm not sure what caused the change in behavior. Anyone have any ideas on fixing this?

This has been happening for months now, on multiple devices (I have tried at least 3 different devices), and on multiple networks.

I have read the articles in here, but they just want me to check network configuration which is exactly the same for all browsers.

If I restart firefox it starts working again.

How can I prevent it from breaking randomly? This is the only browser having issues, I'm almost positive is some bug and not a configuration thing, given that it happens under multiple circumstances and devices, while Edge and Chrome simply keep working just fine.

There is no consistent repro I can give, afaik it is just random, at some point Firefox just decides to stop working and I have to restart it. This disrupts my work and browsing activities as I can lose progress on input forms and similar actions.

something apparently got corrupted in firefox.. i tried running update and i keep getting failed to update.. i have refreshed.. i have uninstalled and reinstalled ...nothing. i am sure there is a folder or file somewhere that is corrupted and i cannnot find it. because even when i uninstall and reinstall fresh. all my bookmarks are there .. how to i start a TRUE NEW install??

I am unable to reach Facebook on both Firefox and Waterfox.

Other browsers (Opera, Edge, Chrome) are able to access Facebook.

I can access other Meta-owned sites (Messenger.com, Instagram, Threads) on Firefox and Waterfox.

This issue exists on both my desktop (Windows 10) and laptop (Windows 11).

This issue does not apply to Firefox for iOS or the Facebook app.

All apps and OS's mentioned are up to date.

This has been going on for over a week now.

I added the Save to Pocket (mini) extension to Firefox 125.0.2 today. When I look at the collection of articles I've saved to Pocket (I've been using Pocket for years) in the browser, I only see 8 articles. But when I open Pocket on my iPhone and iPad, the list of articles I've saved is much more longer (an estimate would be between 50 and 75 articles saved to Pocket). I haven't found any articles in Mozilla support to help me solve this. Thanks

After just turning on my computer running Windows 10, I opened Firefox. I open 1 web site and noticed my computer showed a (16) prefix when loading Firefox. I opened the Task Manager and it showed that there were 15 instances of "firefox" running in the background. All showed a UAC Virtulization of "Disabled". But they also showed using 638.8MB of memory. I do not know whether these are necessary files that must run in the background or if the number of files indicates that my system has been hacked and someone else is in my system from outside. Any suggestions as to validity of these files running or how I might confirm that they should be running. I have noticed the number of excessive background files before but the number is never consistent which makes me fear I may have been hacked.

How can I get access to my own site again? I have been able to access joycefitch.com for years but today I can no longer access it from Firefox.

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 an iMac with Sonoma 14.3.1 with Firefox 115.9.1 esr . It is for personal use, not for a business. I just learned that there is another Firefox version (124.0.2) which is not esr....

Which version should I use and why?

If I should use the "normal" version, how do I replace the esr version with the "normal" one ?

Thanks.

I was playing on this free site called REPLAYPOKER, and it said I was blocked because of something called CLOUDFLAIR, can you tell me what this is please?

It totally blocked me and shut me out of the game

What should I do?

Is Cloudflair a virus? Should I go into the registry and remove it?
