I just upgraded to Monterey on my Mac running FF 101.0.1 (64-bit). I cannot add new search engines to my list of search engines. I'm trying to add DuckDuckGo without success. I have Google, Bing and Startpage. I click on Find More Search Engines, select and add DuckDuckGo but while it appears as an extension it does not appear in the list of search engines.

When I ask WordPress to "preview in new tab," I get a File Not Found screen. (See uploaded image.) This works fine in Chrome (which I rarely use) but not in Firefox, so I'm thinking it might be a Firefox issue. The Tablet and Mobile previews work fine, but they don't require a new tab. I thought it might have to do with pop-ups, so I made my blog's URL an exception. That didn't help. Then I disabled the pop-up blocker altogether. That didn't help either. I've never had this problem before although I've been using both Firefox and WordPress for many years. I'm working on an old laptop (current one is kaput), but I think everything's up to date. Windows 10. Any idea what the problem might be? TIA for any help. This is driving me nuts!

This isn't a question about the "Multi-Account Containers" addons, I am pretty sure that there was a section called "Container tabs" in the privacy and security settings, and I could use containers without installing an addon some days ago.

I can still access by directly viewing this address

about:preferences#containers

But I can't find it in the settings, and this feature does no longer work.

So I went to read recent release notes from Firefox 100 to 101.0.1, but I didn't find any notes to say this feature has been disabled. Could this be an unexpected result of an update?

I use an addon to mute all tabs by default. The problem is that muted tabs have the MUTED text, which shrinks the size of the tab name/title. My old eyes can't deal with that very well.

Is there any way to prevent this text from showing up globally? Thanks.

This question has to do with logging into web sites with an email and a password. Firefox 101.0.1 (64-bit). Windows 10.

On many sites, when I click in the email field, a drop down list of email addresses appears from which I can make a selection using the mouse or up/down arrow keys. Some web sites have as few as two email addresses in the drop down list, others have many more. I recall that one site has about fifteen email addresses in the drop down list.

How can I remove a non-applicable email address from the drop down list?

How can I clear the drop down list of all email addresses?

Thanks.

For ‘few a few weeks now the option to choose where to save files has failed, even with the latest 101.0.1 (64-bit) on windows 11 Home. Any ideas?

This evening I changed the default location to my data area, so at least it will hopefully defaulting to ms 'downloads' folder.

OS Name Microsoft Windows 11 Home Version 10.0.22000 Build 22000

I've just had my browsing interrupted with this recommendation to install an extension: https://torrent-protection.com/download-now/

I was viewing this page: https://www.eurogamer.net/with-the-new-ps-plus-premium-and-extra-sony-opts-for-the-car-boot-sale-approach-to-catalogue-gaming

I was taken out of the page without pressing anything and taken to this recommendation. In particular, it appears like an official Firefox message and security recommendation, with Firefox suggesting I should install this extension for my security. Sadly I don't have a screenshot but it's happened twice this morning already.

Is this really Firefox endorsed? Or are they pushing their extension with fake credentials? How is the page viewing interrupted this way and diverted automatically to another webpage?

My old PC still shows up on sync. I can't remove it because I took it apart when I built my current PC to reuse some parts. Is there a way to remove it from sync or am I stuck with it showing up?

browser.sessionstore.resuming_after_OS_restart = false. My browser still restores on os restart. Startup -> Restore previous windows and tabs is unchecked browser.sessionstore.max_resumed_crashes = 0 browser.sessionstore.restore_on_demand = false browser.sessionstore.resume_from_crash = false

I do not and will not manually close my browser session every time I want to shut down my computer in order to get it to do what it's supposed to. Linux sends SIGTERM to all running processes on shutdown. Firefox isn't handling this correctly, obviously, because if it was, then my settings would be getting respected. SIGTERM is the standard signal sent to windows that need to close gracefully and are expected to still be functional.

NOTE: Do not provide windows-specific support to this thread. I am not running firefox on windows, and I do not possess a windows computer or license.

When I try to go the the site https://tvlistings.zap2it.com/ it show top part of page while it tries to retrieve TV listings, but then the whole page goes blank. It still goes blank when in troubleshooting mode.

Works with Microsoft Edge browser. Any ideas?

Every time I run browser it messages me that downloaded file contains a virus or malware, even I deleted the file long time ago. I tried Ctrl+J "Remove from history", "Clear downloads" and Organize/Delete that entry - Nothing helps. Its deleting, but when I run Firefox its appears again and again. This bug is terrible annoying, please fix it.

I used a siteblocker and i tried blocking about:addons, wouldn't allow it so someone tell me how. im literally trying to prevent myself from removing extension i literally jumped from one browser to another just to make this shit possible please.

Please see the attached screen shot. The icons at the top which allow you to toggle between watchlists are not available, and if you look at the list of stocks, some say "Equalizer" instead of showing the icon. Any settings I need to check?

Hi, just bought a new laptop which is loaded with windows 11, and I cannot download Surfshark vpn, I go to google and it will not even open any surfshark page, I assumed it must be something to do with safesearch, so I clicked on the safesearch button but it does not give me the option to turn it off it just states 'You don't have permission to change your SafeSearch setting. It's locked by the device or network that you are browsing on' !! how do I get over this? any help appreciated,

I've just done a clean install of Windows 11 12H2 and, consquently, FireFox.
