Firefox Community Forum

I've been unable to sign in or send messages through certain sites. Put Firefox in troubleshooting mode and everything seems to be working correctly. How can you tell what settings need to be changed to keep it working correctly? Or should I just leave the browser in troubleshooting mode? Thanks. Jim

I am having problems with Firefox not scrolling (and no scroll bar) on some web pages. The following is an examble:

I am using Windows 10 and Firefox 143.0.3 (64-bit)

Any help would be appreciated.

Two QNAP NAS displayed readable web pages this morning. Early afternoon I updated Firefox with a reset and the admin pages on both servers are unusable. How can I roll back Firefox or recover the earlier version?

Hi After browsing a particular web site the Firefox browser froze with a single search control on the page and all items frozen. Tried to fix it through settings but no response. See attached screenshot. Refreshed Firefox from Control panel->Programs and Features->Uninstall->Refresh Firefox. This reset Firefox and fixed the problem however the Firefox browser lost several settings and add-ons which I had to manually fix. Glad it is mostly all working again!

Putting people before profits since 1998 ___________________________________________________ Wierd. Thanks. Greg

Suddenly today I can not open "You Tube" and I have no Idea why. I have not changed any settings since last evening when it worked fine and have tried to access it, unsuccessfully, in several different ways..

Здравствуйте. Сайты с сервисами от компании Яндекс не работают - не грузятся. Пробовал почистить куки, перезагрузиться, не помогает. Открыл в новом приватном окне, все заработало. В чём может быть дело? Работать в приватном окне - не удобно.

This is a weird one for me. Firefox 142.0.1 Windows 10 Pro 22H2 AdBlock Plus and NoScript as add-ons

https://tvlistings.gracenote.com/grid-affiliates.html?aid=tribnyc2dl

shows me as automatically logged into the site but will not load the TV listings for me in a normal window.

But if I use the same link in a private window it asks for my user name and password then shows the TV listings and continues to work as it always has.

What could possibly cause this? Has only happened for the last 4 days.

im using firefox on windows11. youtube does not load and says no internet connection but other websites work fine. i tried syncing time udating the browser and checking DNS. Still not fixed. What else can i do

We tried 2 different computers, but two different users. Type in the user name and the password and it looks like it will start up, but then returns to the login paged.

When attempting to login to ssa.gov (probably a redirect to login.gov (?)) I get the following in a new tab (with url https://secure.ssa.gov/RIL/SiView.action)

Bad Request

I have Firefox for Linux Mint v136.0.2

I usually browse with Strict but removed for this website, made now difference :-\

While using Facebook, I changed some Meta setting to block ads, then unblocked it. After this, Firefox does not show any Facebook info. Switching to Edge, everything shows as normal. Can't see any setting on the Firefox settings page that controls this.
