Web pages that are supposed to contain emojis are blank. I can highlight where emojis are supposed to be shown but the actual images of the emojis aren't there. about:config font.name-list.emoji correctly contains "Apple Color Emoji" If it is relevant, this has been a bug/issue that has persisted for a couple of months now (can't name an exact date).

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.

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

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?

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?

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

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?

I want to avoid any 'ai assist' searches because I do not find their summaries accurate or valuable enough to be worth the environmental impact they consume. I know my web browser searches are not under the control of firefox, but for privacy and security I kill cookies when I end browsing sessions. So I am not staying logged in to search engines when I finish my sessions, and setting my preferences to 'no ai assist' on DDG doesn't last session to session because the search engine defaults to 'ai assist' searches now, as does google.

Are there any search engines that do not use ai?

Has anyone written an extension/add-on to FF that would add 'minus ai' to all my searches no matter what browser I use? Or otherwise indicate to search engines that I do not want ai-assisted summaries period?

We've got various privacy options built into FF--this is why it is my preference always--and it would be LOVELY to have a 'no ai' option too.

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.

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 tried to use a ftp link setting firefox as the default ftp app, not realizing firefox no longer supports ftp. I am unable to reset the default app and can't find the setting to do so. I downloaded filezilla and wish to set it to be the default app for ftp. Can someone help me with this? Before anyone suggests it, resetting firefox to default settings is not an option.

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.

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

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?

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.
