Firefox Community Forum

Is there any addon or feature within addons management icon (from toolbar) to Disable Extensions and Apps in one-click like Chrome has via this addon?

Win 11 Pro, Firefox Browser-Developer, 147.0b9, 64bit Problem recently occurred. Example it was working fine this morning and after turning the computer off and restarting later in the day this happens. The image below shows faded access to the password manager. Link that appear do not work: Log in at the header and link in password support highlight in the visible text portion. Thanks in advance for your help

First, apologies if this is the wrong forum. This is about the FF Developer edition browser.

It used to show the browser width counter in the top right corner when you resized it. Now in the latest version I no longer see this. How can I get this back? It's a great feature!

Attached is what it used to look like. I don't know what version it appeared in and which it disappeared in.

Thanks!

I keep receiving a popup seeming to be from McAfee security regarding a virus on my computer. It isn't from that security firm. The ad locks my system till I shut off and restart my computer. This is very annoying and occurs on all installed browsers. Is there anything I can do about this annoying thing?

every time I enter some words for a search the system blocks access with an "I'm Not A Robot" process. while I always get past this it is annoying and has only started happening in the last few days.

I have a firefox account that I use for work, which was created with my personal email address - "email"@"personalDomain".co.uk. When I try to log in using it I get a message saying that "personalDomain.co.uk" is not a valid email address. How can I log into my account which was created using this email address? The email address is valid and active, and I do have access to it.

I wanted to open firefox and a new window for new firefox open but did not suggest me to sync my old bookmarks. instead it only asked me if i wanted to sync with chrome browser only. why was i not allowed to save old bookmarks before new firefox updated.

Hello,

I have three devices: a desktop and a laptop with Windows 10, and another laptop with Ubuntu (LINUX).

I read that I can purchase a VPN installation. Do I need to buy three separate VPN installations or one with a single login and password?

Thanks, Pavel

I uninstalled Firefox on my computer and reinstalled it, but when I logged in, the account couldn’t sync, it was as if the sync couldn’t retrieve any data from the server. Nothing happened at all.

On my Android phone, the data is still there, but when I tap “Synchronize now,” nothing happens either. I’ve tried signing out and signing back in multiple times, but still nothing works.

I also tried switching to a different computer and a different internet connection, but it still didn’t work.

What should I do now?

In May 2025 all browsers should have removed the default styling for the h1 element when it is nested in a sectioning element (article, aside, nav, section). I went into Firefox Dev Editions user-agent style sheet and noticed that the styling for nested h1 elements is still the same. I'm wondering why that is the case, since I was under the impression that all the major browsers had completed make the necessary adjustments at the end of May 2025.

My wife's Firefox was triggered from an e-mail link and in the process got updated to release 141.0 The result is that the tabs from the previous verion have not loaded. Can I still recover them?

When signing in to websites, firefox offers e-mail address options that havebeen used before on that site. But right now it keeps offering two, one of which is incorrect, and I thought there was a way to fix that, but right now I cannot remember it.

This is explicitly for sites where I have told firefox *not* to save the password, and it is offering up potential email/login. entries *only*.

I do not want to tell firefox to not offer to autofill anything ever, because that saves time when the entries are correct. but here they are *not* correct and I need to clear them for this one specific website.

How do I do that?

The latest update for the beta version 153.0b1 of 6/16/26 has made my theme stop working although it still says enabled. The theme is: ANIMATED Sakura by candelora 🌸 Theme Designed by candelora © 🌸 Animated Apng Theme I'm using Windows 11 on a Lenovo IdeaPad Flex with Firefox as my default browser. I'm an old lady, not tech-enabled in any way. Please help and thanks.

Good morning, I'm running Firefox Developer Edition 143.0b6 on Linux Mint 22.1. A couple of weeks ago I noticed that when moving tabs on the left-hand side they'll instantly get locked into an inscrutable and seemingly impossible to fix "pinned mode". Is there a way to turn this off? It is driving me crazy. I've looked through Settings > General > Tabs and about:config and didn't see anything relevant. If anyone has run into this or knows a workaround, I’d be grateful to hear it.
