Firefox Support Forum

Hi, I have used Firefox for many, many years and never had an issue till now. And it is only on Facebook., Version 84.0.2 and the one before this one whenever i use facebook and start playing any videos it slows down and lags. I try the same in Chrome and no issue. What did Firefox do just recently to Facebook's website or maybe their security or? Not sure but it is almost making me leave for Chrome.

For a while (since Thanksgiving) every Sunday, Firefox randomly quits and restarts and reloads with random tabs and pop-up ads? Is there anyway to get this stopped??

I'd like to be able to set a background image in Firefox in new tabs and on the blank home page but for some reason I'm unable to do so...

I tried following the instructions on this page:

https://superuser.com/questions/1495946/how-do-i-change-the-background-image-of-home-page-in-firefox

but my new tabs and homepage still come up as blank white. Is there a way to tell if Firefox is even looking at the css file?

I'm using Windows 7 and Firefox 84.0.2 (64 bit)

Thank you in advance!

With concerns about supply chain security, I would like the ability to ensure that the file download matches a recognized checksum.

Downloading from: https://www.mozilla.org/en-US/firefox/78.6.1/releasenotes/ yields checksum SHA256 55249C4861FE521CB32D72785481A146B64812AF2ECE7341FAAA5C79ABC0F395

This does not match any of the checksums available at: https://archive.mozilla.org/pub/firefox/releases/78.6.1esr/

Best practice would be to publish the official checksum along with the release notes.

Is there another way to close the loop on this?

Hello, I update Wordpress pages on downtownlanguages.org. The past couple of days, the site's top menu bar covers up the page headings on all the pages and does not scroll with the rest of the page. I don't know if this is a Firefox problem or a Wordpress problem. The pages display correctly in MS Edge and on my iPad. To my knowledge, I've done nothing in WordPress to cause this to happen. I have refreshed Firefox and cleared startup cache but it did not resolve the problem. Please help. Thank you! See https://downtownlanguage.org/donate for an example.

It's not the monitor brightness giving the problem. Turning up the overall brightness makes everything too bright . I just want to turn up the brightness for the videos that are played through the browser.

Anyone have any fix for the terribly slow Facebook scripts. Hangs for 30 secs. Warning from Firefox. Today whole brower just closed. It gets slower and slower the longer you use Facebook. I know the problem is the script. But can't you do something clever?

Hi guys. First of all sorry for my bad English ^^ I'm using FF from Italy, and we use for several things a smartcard, using certificates and similars.

So, the problem is, when I put the smartcard in the reader, firfox stop responding. I have to restart the browser, then FF recognize the smartcard and I can login in websites.

This problems started with FF 84.0.1 and continue in 84.0.2

How to resolve? Thank you!

I have always been able to use Firefox as the default browser when launching hyperlinks from MS Office products. Last week, i received notice that FLASH is no longer supported and should be removed.

I did this.

Now - when i have a hyperlink in ANY MS product - it does not launch. When i change default browser to MS Edge - they work

How do i get this back to working in Firefox

When I browse in full screen mode and try to save something (a web page or a picture... it doesn't matter) the dialog box does not show up on the screen - only two big buttons on my touch bar which allow me to "cancel" or "save".

Is there a way to fix that?

After using Facebook Watch on Windows 10 for a while, Process Explorer will show one Firefox Process with a huge amount of memory, which takes up to two minutes of high processor usage to be released once the tab is closed. This slows work with the other Firefox tabs. Firefox Task Manager "forgets" about it as soon as the tab is closed. This does not happen on Android.

This problem has been around for a long time. Just thought I'd see if anyone has any ideas other than not watch FB videos.

OS: Windows 10-64 Home or Windows 10-64 Pro Version 20H2 (OS Build 19042.685) with all current updates Firefox: 84.0.2 (64-bit)

For about a week now a few websites are taking a long time to load on my 4 PCs (examples: ebay.com, walmart.com, pch.com). If I click the link on the search page it takes almost 30 sec to load, right click and open in a new tab same time, and open a new tab and type or paste address the same amount of time. Most other website open almost immediately.

The issue does not resolve in safe-mode or if I manually disable add-ons. I'm using the default theme.

All websites load without issue on Chrome and Edge.

I have 2 separate firefox accounts, one is my personal profile and the other one is for school. I recently made the switch from brave to firefox and I had the same thing but the profiles were pinned to the taskbar for easier access. I cant do this for firefox because i pin one shortcut and I right click the other shortcut but its connected to each other so it shows unpin from taskbar.

When FF is automatically updated when "allow firefox to install and run studies" Is there a identifiable version in FF? and if so how can that version be obtained?
