Firefox Community Forum

I recently opened Firefox to see a new flagged warning under my toolbar that says "The security sandbox is disabled. Your configuration is unsupported and less secure."

I have gone into about:config and adjusted every security.sandbox element to see if that would change anything; it did not.

I am running on Windows 11 Home so I cannot install or properly run Windows Sandbox.

I would either like a solution to enable the sandbox once again, or just remove the notification from the toolbar.

Windows 11 : Fix this ASAP I delete all tabs, close firefox, reopen and I get 5 tabs which seem to be STUCK. I delete 3 of these tabs, go about my work, none of those 3 are open, and I shut everything down. When I reopen Firefox, those 5 "default tabs" (the 3 I don't want have migrated over from I don't know were - both Chrome and Edge open with New Tab.)

I have enough other problems in my life - and done't tell me to create a new profile. At that point I'll kill firefox and end my donations to Mozilla.

bold text how to stop address bar search. its very wrong you have a fake search bar in the screen i want to search from a search bar not the address bar

I can't open Firefox at all, so I downloaded Firefox again, before I got your message. The Crash ID: ⁨bp-958359b9-d3d4-4cba-aa19-4dcbc0260313⁩

That is the only one, not five crash ID's. I couldn't open Firefox to find an omni.ja file.

I can't import or access my bookmarks or passwords on the new Firefox I installed. Would you please be able to help with that?

I have just downloaded NordPass Password Manager. I think I have added an extension for this in Firefox, but I can't tell if it has been successfully added.

I am using Windows 11 Home Version 25H2 OS Build 26200.8037 64 bit operating system

i need the 'home' button. it is not included in the 'customize' items so that doesn't work, as it is not actually there with the other items. please tell me how to get it. thanks. it's ridiculous working without one.

Hello again. Yous answer Did you check the backups in the bookmarkbackups folder in the profile folder to see if there is a recent backup with a promissing bookmarks count?

My reply No ints empty

When v143 was released something happened to the shortcuts row(s). Regardless of refreshing efforts, rolling back versions, and searching the forums, there's no way to consistently get the shortcuts back. Sometimes they appear with a new browser instance, sometimes they don't. They don't appear with new tabs, and they don't stay when they do appear with a new browser. Grrrr. Please restore the shortcuts!

I updated firefox through apt, and since then, have not been able to log into twitch I am on ubuntu 24

apt list --installed | grep firefox firefox/mozilla,now 144.0.2~build1 amd64 [installed]

Attempting to log in returns the generic "Your browser is not currently supported"

Recently a "gear" icon has appeared on the bottom left of my screen while using Mozilla. It relates to moving the tabs. I don't want to do anything with my tabs. How can I get rid of the icon? The icon reduces the horizontal screen space available. I have a small laptop so this small amount of space is important.

Thanks for your help! Cindy

I read the existing articles and followed them, starting with "manage bookmarks". When I click on restore, there is a list of the last 15 backups by date. EVERY one of them results in an error message "unable to process the file".

Manually searching for bookmarks.html or json, resulted in nothing found at first. Then I discovered the path to the bookmarks folder were all hidden folders (after the 'user' folder). I got them to display in file explorer ('show hidden files' selected) and tried to manually select the JSON files that way, to restore bookmarks. That also did not work, resulting in the same message depicted below.

Please help

Why has Video Download Helper v9 by Michel Guteriezze been replaced by Video Download Helper by vdh? The original versions were perfect. The VDH version 10 vdh is straight junk!

Why https://www.wunderground.com/dashboard/pws/IWOJEWDZ128 my weather station site for several months shows status offline and direct me at once to main site wunderground.com ? It is only on Firefox, Chrome, Android works normal and here it is online. Win 11, Avast Free, blockers (active adblock, ublock, ect.) In past several years was all ok I did change nothing with settings, blocker were in past also. What and where to look for?

I can submit posts on X using Chrome, but Firefox, for some reason, has cut off the portion of the posting box that contains the submit button and other edit features. It simply vanished as of March 10 2026.

I have attached screenshots showing FireFox vs Chrome.

I cleared cache and cookies to no avail. I have the latest Firefox version. 148.0 64 bit. Windows 11 operating system.
