Firefox Support Forum

I note that there are 399 posts referring to this problem. The problem has existed on my PC for about 4-5 months.. DELL support has checked my computer, we have cleared cache and browser and tweaked other controls but nothing helps. I have no problem using Google Chrome. If so may people are having the same problem surely Firefox should be making an effort to fix the bug??!! Just drafted a reply to you from Firefox site but as frequently happens message appeared -

 Something about oops and an error message. When it occurs drafts do not save and messages do not transmit.

Sorry the screen print will not copy across.

I use Firefox as my main browser and it is inconvenient to have to swap between Firefox and Chrome

Can Firefox please fix this problem?

thank you mlmg

When I try to access MediaFire it doesn't load and get errors etc. And other sites are slow etc. Is there anything I can do to fix it? Also how do I contact FireFox email official support? I don't like asking on the forums since I want a legit agent ;p

Firefox crashes when switching between tabs. Worse than usual crash, the last page i was viewing is there but unresponsive to mouse or keyboard including contr-alt-delete. Must push and hold the power button on my Dell XPS8940. Windows 10 Home 21H2 OS Build 19044.1586. Windows Feature Experience Pack 120.2212.4170.0.

There was a window with 7 tabs, 1 playing a youtube video and 5 with videos not playing, one other site with no audio and another window with a website streaming only audio. When the system stopped, the speakers made an odd sort of buzz sound until powered off. I am on the latest version FF 99.0.1 but a similar crash happened on version 98.0.1. Before that this Dell never locked/crashed up this way.

This Dell PC has Realtek audio just like our HP W10 laptop and they both had issues when new with all sound not working when playing a youtube video only in Firefox (HP Feb 2021 and Dell Oct 2021). Launching Groove Music and playing an mp3 always got the sound working. Problem did not cause any program to crash. Windows updates to drives eventually fixed the problem but it only even happened in Firefox. Current problem is new in the last month or two and only on Dell.

While using Yahoo email I tried to access the 'Notepad' page and get a message saying to Download a new version of Firefox to see the 'Calendar' even though I was trying for the 'Notepad' not the 'Calendar'. If I try for the 'Calendar' I initially get the small right-sidebar version fine but if I ask for the full page version I get the error message again. This does not happen if I access Yahoo through Chrome-browser. I have repeatedly done the download to no avail. (I have version 99.0.1). I am attaching a screenshot of the error message. Thanks for any help. No rush.

When my computer shuts down unexpectedly (due to power issues etc.), after power on the computer again it takes too long to search for a website (Not restoring previous session but actually searching for anything else)

On Firefox for Windows (on Windows 11 release 99.0.1), the first setting in Settings is "Open previous windows and tabs". This is incorrect. It doesn't do this. When checked, upon startup, it will restore one window, its tabs, & maybe its sessions (?), and it will send all the other Windows & their tabs to the bit bucket.

Users: KNOW & HEED this warning! Team: Please take what you've already done for that window and merely do it also for the rest of them? In the mean time, please change the wording to something like "Open one of the windows and its tabs". Ideally, identify which window has been chosen for this.

Thanks, and be well.

Firefox only shows a black box when i try to run an embedded video. It works fine on other browsers, specifically Microsoft Edge. I ran it in troubleshooting mode which fixed the problem temporarily but reoccurs when computer is off and then turned on.

This was going to be a question about Firefox being unable to display the file picker dialog, but I managed to find a solution that worked for me along the way. Since it was nowhere near the top of Google's results, I thought I'll share my solution in the hopes that this would help someone facing this same issue.

The hardware:

• Asus UM425IA Zenbook (AMD Ryzen 7 4700U CPU)

Worked in:

• Ubuntu 20.04 LTS
• Firefox provided by APT repository
• Xorg display server

Not working in:

• Ubuntu 22.04 LTS
• Firefox 99.0.1 provided by snap
• Wayland display server
• File picker worked briefly on fresh install, but something (not sure what) quickly breaks file picker functionality

The symptoms:

• Firefox stopped being able to open file picker dialogs
• Right clicking an image and selecting "Save Image As..." does nothing
• With forms that accept file upload (such as on this post question page "Add images (optional):"), clicking "Browse" does nothing
• File downloads work correctly when set to "Save files to ..." under Settings, but nothing happens when set to "Always ask you where to save files"
• No response to "Ctrl + O" open file shortcut

Similar questions and solutions:

• Fixed by reinstalling Firefox
• Fixed by resetting Firefox
• Fixed with a restart on a Mac
• Fixed by downgrading to Ubuntu 16.04

Things I tried that did not work:

• Disabling hardware acceleration
• Starting with add-ons disabled
• Troubleshoot mode
• Clearing startup cache
• Clearing cookies and site data
• Clearing history
• Refreshing Firefox
• Creating and using a new profile
• Deleting the `xulstore.json` file from the profile directory
• Toggling all permissions under Ubuntu Settings > Applications > Firefox to off and then back to on
• chmod 777 ~/Downloads
• Disabling native file picker "ui.allow_platform_file_picker = false"

And finally, what fixed it for me was to go into "about:config" and change "widget.use-xdg-desktop-portal.file-picker" from "2" to "0". Credit to this post that clued me in.

I really hope this saves someone else 2 days of hair pulling and I would appreciate advice from someone more knowledgeable than me on:

• Why this fixed the problem
• Whether I should be opening a bug report either against Firefox, or Ubuntu
• Whether I should also be changing "widget.use-xdg-desktop-portal.mime-handler" and "widget.use-xdg-desktop-portal.settings", both are currently set to "2"

I had been using Firefox browser for awhile, but because of playback performance issue, I have to using another browser just for video playing, especially for 4K video.

Compared to Edge, Firefox seems taking more resources to playback the YouTube video and more heat. When look at the Task Manager, the Video Processing is 0%, and GPU is running significantly more resources on '3D'.

Hello,

We have a solution to display a property sale detail in iframe. The first time it's displayed only the not small images or without srcset.

Points of note: - The iframe is resized by javascript to take the height of the content height at loading. - Most images are defined with a srcset.

It's seems the browser begin to download 480px images as it should and the height resizing of the iframe cancel the requests (NS_BINDING_ABORTED) and it request the image in the attribute src but does not use it. The image preview in the inspector also display "Unable to load".

Refreshing the page display the images (with or without cache), you need to restart Firefox to have the issue with the same images. It's work correctly under Chrome.

Here an example https://test-agpwrapper.agence-plus.com/agpwrapper?k=cPZw_2neX-c At the end you have photo 3, photo 4, and photo 5 instead of the images, it's displayed if you refresh the page.

Thanks you for your support.

An example of the problem: Firefox does not rnder the page https://www.ebay.co.uk/itm/164957094349?_trkparms=amclksrc%3DITM%26aid%3D1110013%26algo%3DHOMESPLICE.SIMRXI%26ao%3D1%26asc%3D238391%26meid%3D7ab2984ab89c490d9d19c64154175f61%26pid%3D101195%26rk%3D5%26rkt%3D24%26sd%3D402300560285%26itm%3D164957094349%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplAMLv5PairwiseWebNoToraCoCoViewsNoHighIdfOrSortByFinalScoreBlenderWithPromotedViewItems%26brand%3DUnbranded&_trksid=p2047675.c101195.m1851&amdata=cksum%3A1649570943497ab2984ab89c490d9d19c64154175f61%7Cenc%3AAQAGAAABQJxAynw2%252BiqzPDrRSEdA1OtGPHECjXiPIHTAGGaFXyfAhhOOcI0evIqLAV5dzxfkWlXm6ww1t0P09GMtcbSuFZjf5HidAoI3BLEE5q9IzcpZf1TZn1%252BLTOgqc1OD9sLjUiICuetx8VnxmROZ45L3noIgk65aQJuCoPA0d32OWfO52LE5XKsl22M11N9hzVfwHgluh%252F5HKiKhVl5Tsx0wb0b0dE30VWGeE6KisowiOj70Bzel9x4sBW7H8CN3vmNB2XZxJ3WwTx5I56fEAax5jK2zMEYDr0au%252Fk%252FCwLpDP%252BFvJPj2%252BRIxUzguSZgC5le17lkTY6CuGTF9xYRefAzw8ks%252FtcGsNkPKFb7ZfNXkOLe1k28NQbsvOuhPVcLk1pb3Joal6Ssw3egfQv4HF3D4vL6v6k1xWnbVepvH8lGXPENE%7Campid%3APL_CLK%7Cclp%3A2047675&epid=23034767275

properly. A lot of the text comes out in very narrow columns. The problem happens quite often on eBay. Chrome does render it properly. Could you please look into this? Thanks, Jon

Under User Account Control I get the message : Do you want to allow the following program to make changes to this computer (the message comes up on my laptop (not this one). I try to say "yes" but the computer doesn't accept the command. The computer shows that it is connected to the internet but I cannot go into my e-mail. Something in Firefox is being blocked. How can I unblock?

Over the past day or two I've been having an issue with various Google products where they work normally after a fresh restart of Firefox but then fail after a period of time. In Gmail, I get an error at the top of the main page saying 'Oops... the system encountered a problem (#001) - Retrying....' at first and then saying 'Not connected.' later. In Youtube, it starts off as thumbnails not loading but clicking through to the video still works. Eventually it stops working and clicking through to a video says 'Not connected to the internet'. Google search will load at first but not go anything when clicking search. Later it won't load at all.

Closing Firefox and reloading it will let everything start working again for a little while, but it stops working properly again within 5-10 minutes.

Loading Gmail in a private window seems to work and stay working. I haven't tried this with Youtube or any of the other google products.

I haven't noticed any issues with any of the other websites that I would use normally.

So far, I've tried disabling hardware acceleration, I've cleared cache, cookies and history. At the moment, I've manually removed my profile, uninstalled Firefox, reinstalled it without any addons or using Sync and the problem is still occurring.

This is with Firefox 99.0.1 (64-bit) under Windows 10. I've been using Edge so far today and haven't run into the issue with Edge. This is on my work laptop that's connected to a domain and is using Sophos Intercept X endpoint protection.

IT'S MAKING ME CRAZY - so bad that I've even tried MS Edge! Ewwww.... I read in the HELP files and online that I should be able to change the config to 1/1 after unchecking option to let Firefox control things in my settings. However, it does not pop up the change config box - and, I later read that it is not available any longer. This is killing me! Thank you for helping!

My microphone does not work properly in Firefox, it sounds very low and bad.

I have a Corsair HS35 Stereo headset and my sound driver is Realtek HD Audio 2nd output.

I have tested my microphone in other browsers and other kind of applications like Google Chrome, Brave, Windows Voice Recorder, WhatsApp Desktop, etc. and the microphone works fine. It only works badly in Firefox.

I did the test with a portable version of Firefox, and, as with the installed version, the microphone was malfunctioning.

I've also noticed that Firefox lowers the microphone volume automatically (how do I prevent this?), yet even if I turn it all the way up it still sounds very low and bad.

What can I do about it?

Thanks for the answers

I was watching anime today on some site and my firefox was downloading many files without my knowledge into my download folder. I'm worried that it can be some viruses? This is a screenshoot. Should i be worried? Thank you for help.

My problem is this:

If I click on the open new tab button, and then I keep my cursor there, such that I get the little tooltip "Open a new tab (Ctrl+T)..." , Firefox will stop the address bar from updating---it won't show my keyboard inputs, not will it search, or do anything else. This will resolve itself after I move my cursor away from the open new tab button and the tooltip stops showing, even my inputs will appear there.

This quite annoying, especially when opening a tab to search for something quickly...

The latest example is the button to sign into LinkedIn. It is not working in Firefox, but it does in other browsers. I have other examples just from today. I have used firefox as default for many years. I assume this is a security thing, but these are basic links. I have no add-ons or other complications. Most times, I do not even realize there is a problem, but when I feel something is wrong, I try another browser and it works. Thank you.

firefox is very slow, crash several times. i need to close and reopen.

it comes on average 2TB of Ram with 4-5 tabs open. version: 99.01 64 bit

- slow when using youtube

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?
