Firefox Support Forum

Sometimes all add-ons / extensions break randomly and are disabled (the icon of the extensions is also broken under "Manage Your Extensions").

The extensions are visible under "about:addons", but the slider is turned off and the icon in front of each extension is broken / empty.

It seems that deleting these 2 files- compatibility.ini and extensions.json inside the firefox profile folder, usually fixes the issue. Only these 2 files though, don't delete anything else.

No need to mess around with the ff profiles or anything else, just deleting those 2 files and restarting the firefox usually fixes the issue with the "unregistered" addons.

This thread is for the search function, as I found some VERY old and outdated suggestions for the aforementioned issue using the search function.

I wonder what causes the extensions to "unregister" randomly.

How do I perform very basic editor functions like add/remove/move a page in the new Firefox PDF document editor? I am in the Mainstream Firefox 124.0.1 64-bit. Thank You, David

I'm using the current version of Firefox 124.0.1 (64-bit). I recently noticed that when I print -- there's no webpage title or URL address with date on the bottom even when I have checked and selected print headers/footers before printing. Is this a bug? Can you please help me? Thank you.

Every time FF does an update it deletes my saved sites on the FF home page. When I try and put them back in the blank spaces it will not let me. I have tried reinstalling FF and it does not help at all. I try in safe mode and it does not work either.

Safari has no problem with https://meijer.com, but Firefox flags it as untrustworthy and won't let me connect. I am using Avast! antivirus. Brave browser also works. I am using 124.0.1. I see there is a 124.0.2. I'll try that next.

Hi

When I scroll text for some reason, Firefox stopping scrolling very slow. It's almost take up to 2 seconds. Very annoying smoothest. I have stopped scrolling already but Firefox still scrolling and finally very slow stop it. I can't focus on the text because it's still slows down the scrolling.

How to fix that!?

Hello,

Why doesn't "open previous windows" work? It can't be checked off in settings. It seems other people have this problem. Are there any fixes? I have a Windows computer with Windows 11. It works on my Android phone, but not on my desktop.

Thank you, Tom

Is there a way to set the default view and sorting for file upload folder?

The default for me is, detailed view and sorted by date.

I wanted to change it to large icon and sort by name, so it's easier to upload images. but I have to change the setting for every individual folder, is there a way to just set it as default?

This is the procedure I followed:

Close firefox

Copy previous.jsonlz4 file to the main level in the profile

It has all the tabs i used to have in it because I made a backup a few days ago

Rename the file to sessionstore.jsonlz4

restart firefox

I get the same single tab I had before i did this

when i go to history tabs, all that is there is the single tab i currently have

Appreciate your help/gary

I've installed firefox and weirdly when I use youtube or just browsing the CPU is 250 and it's draining my new mac really quickly. This did not happen before on my previous mac. Seeking some help and answers, went to Apple genius bar and they've stated is the firefox application that is causing the fast drain of power.

I am setting up a new mac computer (Mac book Air M3 with Sonoma 14.3). I have installed Video Download Helper. The icon appears in the Applications folder and the Dock, but not in the Firefox toolbar. How can I get the icon back? Many thanks.

I suddenly started a thick outline shadow around dialogue boxes such as the Google search bar. I thought it was them but it is on all websites and only on Firefox. I did not change anything. I did restart my pc yesterday but it just started this morning when I opened Firefox. Firefox 124, Windows 10 I don't like it and want to get rid of it but I don't know how.

Could you kindly advise? WashingtonPost.com does NOT ask to accept cookies even after I deleted all cookies, website data and cache (but in Opera it does ask for cookies), after Firefox automatically deleting cookies and website data after closing Firefox, and after cleaning cookies, website data and cache with Ccleaner — WHY? Which mechanism of Firefox is exploited by WashingtonPost.com? And what should I do? Thank you!

updated to Version 124.0.1 (64-bit), now adblocker ultimate blocking website ( are you human? not a robot requests). There's no button to confirm.

I can get to log in screen ( Sams' club) but it goes right back to the are you human screen?, 

I can access the website if turn off Adblocker Ultimate. Adblocker appears up to date. When I disable Adblocker there is still a request, but this time a button below to press and hold which takes me to login screen. I can successfully login then. Reporting the issue which began within 5 min of the last Firefox update. I updated 3/23/2024

Hi, I seem to be increasingly having problems logging into some sites. Mostly it seems to be football sites - https://supercoach.heraldsun.com.au/afl?destination=%2Fafl%2Fclassic&apiIdentifier=afl_classic and https://www.fanfooty.com.au/. Both are working fine in Chrome with the same username and password. Recently I couldn't log into my AGL electricity account, then suddenly, it came good on it's own. I have cleared the cookies but that didn't help. Cheers, Ian.

Yesterday I was playing videos on rumble fine. Sat my laptop down, picked it back up after waking up and suddenly no sound on any rumble.com video. Youtube plays video and audio fine. So does X and truth social. In fact, any website plays audio EXCEPT rumble.com. Its not Windows related. Its firefox related. I installed Chrome and rumble.com plays with sound fine. I uninstalled firefox and reinstalled and that didnt fix it. I have rumble installed via WebCatalog an it plays videos and audio fine. I then installed Firefox nightly and never signed in or anything and still rumble isnt playing sound. Its rumble+firefox=no sound. And it appears to be happening to others too on other help forums. DOES ANYONE KNOW HOW TO FIX THIS?

How do I stop firefox from automatically downloading files from the internet when I click on them - without even asking me if I want to download them in the first place. In "Applications", selecting "Always Ask" in "Choose how firefox handles files etc" does not work. Firefox never asks. If it cannot be disabled, I will have to stop using Firefox.

I have been using Windows 10 with Firefox browser and Google/Gmail for many months. I also have been using Norton 360 and other Norton programs for many years. A few days ago, I updated Norton Utilities Ultimate and after update ran it for standard options. Before that update, I could start Google and still be signed in and start Gmail and still be signed in. Now, whenever I close Gmail or Google, I have to sign in whenever I start Google/Gmail. I tried to get help from Norton (see attached chat printout), but they said it was not a Norton problem and to contact Google. When I researched the problem with Google, it indicated that the problem was related to cookies but did not help correct it. I tried Firefox Help and could not find any useful information. I then changed to Google Chrome browser; that works and I can start and stop Google and Gmail and remain signed in. If I go back to Firefox, I still have to sign in every time I start Google. Appears to me to be Firefox or Firefox setting problem. Help!! Gordon gordonandpatti@gmail.com
