Firefox Support Forum

Hi there,

Occasionally (every half hour or so) I will notice there are two Firefox browsers open (I use nightly), one which I am using and another that fills half the screen but is stuck as if it were trying to load up. It cannot be closed or minimized unless the 'Firefox has crashed' message pops up, I was wondering if this is an issue faced before and can be fixed or something new?

Thanks

I have noticed that after using Firefox for a while when I close it the trace is left of the page I been watching or working in. Mainly it is visible through transparent windows (visibility stays after the Firefox window has been closed) and when the desktop background is changed to a dark blueish colour I can clearly see the faded Firefox page. Restarting PC changes nothing, the faded trace stays. It clears out after not using Firefox for a quite while. I really enjoy and prefer using Firefox to other browsers but this problem has been annoying me for a some time already. Any suggestions for fixes ?

Upon start up Firefox (ver 84.0.2) will use 100% of my HDD for 45 to 60 minutes, freezing my PC for that entire time. This also happens when I start Firefox in safemode, and when I start my PC in safemode with networking. I have cleared the cache, I have deleted each extension, I have even deleted each and every bookmark. I have deleted, redownloaded, and reinstalled the latest version of Firefox. I have even done a full reinstall of Windows 10. My HDD is less than two months old, and shows no errors when scanned. This problem does occur with other browsers, but not for the same length of time, Chrome will use 100% of my HDD for one minute, tops. Once Firefox stops doing whatever it is doing to my HDD after an hour or so, it will run in the background using 0% of my Disk. Through all of this, the Memory use goes no higher than 18%, and CPU no higher than 45% for a few seconds.

If I open a second tab in Firefox, or a separate instance of Firefox, it does not use the HDD very much at all.

If I close all Firefox instances and then reopen a new one, it will, again bog down my HDD for about an hour.

The unacceptable solution I've come up with is to open Firefox immediately after turning on my PC and to leave it running in the background for that entire time.

I am busy doing my schoolwork and firefox keeps on crashing, namely by over-using the CPU on my laptop too much. I have tried numerous routes, such as reducing the number of browser extensions, using one of the certified performance-boosting add-ons to reduce CPU usage, I even tried limiting my tabs to a maximum of 10, all of them have failed to improve performance. This is not even mentioning the browser-induced bluescreen I just got a few minutes before writing this.

I have refreshed my Firefox, because it was slow.

In the description was written: Firefox will save these items:

   Bookmarks
   Browsing and download history
   Passwords
   Cookies
   Web form auto-fill information
   Personal dictionary 

Ok. It's fine. But after refreshing the Firefox how can I restore these elements?

Please send me a step by step instruction, without referring the webpage, because I have read it and it is not clear for me.

Where is my older profile? Where is my new profile? How can I move the elements from the older profile to the new profile?

Thanks a lot: Mihaly

Hello Community,

I would like to start by sharing this screenshot with you as it help gain a better picture with the below info : https://snipboard.io/9z1FVU.jpg

I tried to access this URL (on my computer using Mozilla browser): torproject.org but after quite some time to load I got the error message in the screenshot.

I tried to access the same URL on my phone through the Mozilla app and it worked.

I have experienced the "The connection has timed out" with other websites as well.

Two questions.

1) Since I want to download Tor on my computer, how can I get it to even open up this webpage?

2) How can I prevent future "The connection has timed out" error messages?

I am looking forward to your assistance.

Thank you

When I click in a result after a search for an adress using DuckDuck Go in FireFox the browser quit thenself for a second, with a entire black screen, and returns. This issue not occurr in Goolge Maps.

Version FireFox: 84.0.2 Windows 10

My employer uses the G-Suite at work. I use Firefox on my company computer and on my personal computers.

On the afternoon of Jan. 20, I lost access to Google Calendar. It only shows the dates and a crawling blue ribbon, as if it's trying to load my calendar and failing.

I ran some tests with my company computer and my personal laptop. Here's what I found:

• I can access all the other G-suite components (Gmail, Contacts, Google Drive) from Firefox on both computers.
• I have the latest version (84.0.2) on both computers.
• I can access Google Calendar (and the rest of G-Suite) using Google Chrome and Microsoft Edge.

Sounds like Google implemented something in Calendar that doesn't get along with Firefox. Has anyone else seen this issue?

During class today, Firefox unexpectedly crashed on my Windows 10 PC after downloading a pdf file from my History teacher. Now, when I try to open Firefox, a transparent box quickly appears before disappearing again, not opening Firefox. I have yet to find a solution that has worked.

Since yesterday, Firefox doesn't open. It does'nt appear in the task manager, i tried to uninstall anr reinstall it, I tried to create a new profile by executing firefox.exe -P but nothing is openning, I tried AdwCleaner, Malwarebyte but nothing seems to work.

I just got a Pi 4b with 8gb. So I picked up SanDisk MicroSD 64 GB with 170Write.

Loaded the Ubuntu Desktop 20.10. It boots in 30 seconds. Wow...

Printer setup was super easy... Had to add Clementine to Play M4A music from itune files.

Ok... Loaded just fine. Plays Great. The Ubuntu 20.10 comes with Firefox 81.0 browser. My favorite Browser. Went out to my Favorite Anime site to play some video. Animefreak.tv

Error loading player: No playable Sources Found

Well the Video Codec plugin not there. Checked the Add-ons Enabled

 OpenH264 Video Codec provided by Cisco Systems, Inc.

This plugin is automatically installed by Mozilla to comply with the WebRTC specification and to enable WebRTC calls with devices that require the H.264 video codec. Visit https://www.openh264.org/ to view the codec source code and learn more about the implementation.

 ! OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly.

So I installed the new version of Firefox 84.0.2 (64-bit). ok. I am using it now. No Video play back in Firefox on Ubuntu 20.10. Same Problem. I turned on the Allow Automatic updates in firefox openH64 Video Codec. Maybe it will update and install. Well I am not holding my breath. Its to bad, because the Pi 4b is just as fast as my Laptop HP envy running win10.

If you can find a fix. I would be grateful.

How is this still a thing? Chrome can open any PDF file correctly. Any PDF file I open in Firefox shows the text as blank spaces, and I get the message "This pdf document might not be displayed correctly". Why? Why do I, with Firefox, need a 3rd party PDF reader? I shouldn't have to. Even Microsoft Edge gets this right.

Back to Chrome, I guess...

When I search using Firefox I keep getting a google pop-up which requires me to agree to google's terms and if I refuse I cannot proceed with my search. If i try to open a new search the google pop-up returns but with out the request to agree to google terms. Firefox is my default search engine. How can I stop this very annoying google pop-up?

Hi Forum Folke,

I keep having issues with Firefox (84.0.2) when trying to make online purchases... the dialog window (PayPal or whatever) that should pop up doesn't. The purchase process stalls because the next step doesn't happen. I have to use Chrome to make the purchase instead. This didn't happen until the last upgrade, now it's a frequent problem. Doesn't happen on all sites or with all vendors, but often enough to be a headache.

Since this is a 64-bit browser, should I be using the 64-bit version of Java, or does it not make any difference? If it does (or might) make a difference, how do I tell FireFox to use the 64-bit version (installed in the programsx86/Java/32-bit directory)?

Thanks for your help!

Since this morning, Firefox fails to show any pages, this includes options.

Both Chrome and IE render sites without issue.

I have attempted the following: 1) Reboot 2) refresh Firefox 3) remove and install - Without removing any profiles 4) remove firefox, delete profiles, and install

Nothing has worked.

My boss can open her Google Calendar in Chrome and Edge, but not Firefox. It just sits on a blank page and tries to load, but never does. Nothing more than a blank page and the spinning circle. We have:

Cleared the cache Restarted the browser

I saw someone on Reddit posted they were having the same problem 30 minutes ago (2:45 pm EST). However, my calendar opens find on Firefox on my own computer.

Any ideas/solutions? Possibly related to the upgrade to 84.0.2?

Thanks matt
