I want to turn off the hover preview feature. First I went in settings, but that disabled only the thumbnail (browser.tabs.hoverPreview.showThumbnails in about:config is set to false and saved). Then I went in about:config and manually set browser.tabs.hoverPreview.enabled to false as well, that disables the unwanted feature completely.

But every time I restart the browser it's turned back to true (just hover.Preview.enabled, not hover.Preview.showThumbnails). Can I save my settings? It's annoying that I can't opt out.

I have disabled sponsored shortcuts in Firefox settings, and did this when I first set up my browser.

Today when launching my browser the first link in my shortcuts was to @Google which I specifically do not use. I do not use google search. I do not want google search. I do not want cookies or content from google.

Why was this sponsored shortcut pushed to my browser after I disabled sponsored shortcuts?

When I login to my Virgin Mobile Canada account (at https://www.virginplus.ca/myAccount/logon-smart.do), it displays the error:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. The URL for the error message starts with https://www.ges.bell.ca/siteminderagent/SmMakeCookie.ccc?SMSESSION=

After getting the error, when I got back to https://myaccount.virginplus.ca/, I find that I am logged in. Also, I do not get this error with Edge.

I use Mozilla on two things, my laptop and my android cell phone. The syncing on my cell phone appears to work perfectly well. However, when I am on my laptop, I am unable to view my "Tabs from Other Devices" - It will show me tabs from days ago. I've tried manually syncing on both devices but nothing happens.

The only thing that seems to work is if I log out of my Mozilla on my cell phone and log back in but then it will stop syncing again.

If something else isn't syncing, I honestly don't notice because I don't use anything else much.

Hello!

I have tried every recommendation I have found to stop the very annoying picture in picture feature in YouTube: 1. Unchecking the Enable picture-in-picture video controls option on the Firefox settings 2. Typing about:config in the address bar and press Enter, searching for "media.videocontrols.picture-in-picture.enabled" and setting it to false.

When I am watching a video on a play list and I want to get out of it and I press the back arrow on the browser tab, I get the annoying pop PIP video. Is there a way to totally disable this PIP feature?

Thanks

After updating the Mozilla browser, two sites related to watching TV movies stopped opening - Apple TV and Canal +. The Apple TV site does not respond at all, Canal + shows an error. Clearing cookies doesn't help. Another browser, Chrome, opens pages normally.

Hello,

 An update or two (maybe more?) ago, the plus sign with which we add shortcuts to the Firefox browser home page/new tab page disappeared, so now we can no longer add shortcuts on the home page/new tab page.  Please help.  I am running Firefox Version 129.0.2 (64-bit) on a Windows 11 Pro 64-bit if that makes any difference.  Thanks.

previous tabs not opening on initial boot up - I have it check for that to happen, but only a single tab opens when I boot up computer. I can find the last session in "Recently Closed Windows"

Hi!

First of all, mods, if I chose the wrong category and this had to go in "customize settings and preferences" feel free to move it :)

So, for several reasons I decided to completely disable SSL and the old TLS 1.0 and 1.1. I still didn't decide if TLS 1.2 is still important or it's enough with 1.3 so for now I am leaving them both. I did this system wide, with PowerShell, following the instructions in THIS THIS article.

But then there's Firefox. I don't know if Firefox can establish SSL (or old TLS) connections despite the system "ban". But I came across THIS THIS article about how to enable TLS 1.3 in Firefox and when I went in about:config and I typed "security" I saw that there are a lot of voices with SSL and a lot more about TLS than just the security.tls.version.max mentioned in that article, so I am here to ask you what to do to be 1000% sure that all SSL and older TLS are completely disabled in Firefox, and that only TLS 1.3 is enabled.

If you have reasons to believe that disabling TLS 1.2 is not a good idea, let me know, but in THIS THIS article I've read that 1.3 is much better and it's anyway backwards compatible with 1.2 in case some server only supports 1.2, so I decided to leave only 1.3.

Thanks!

When I copy something to my clipboard I can paste it into Firefox. Into web pages and also into the URL bar.

But when I copy something in Firefox, it does not go to the clipboard. The clipboard still hast the content which was already there.

Also strange: When I cut text in a textarea, input element or the URL bar, the text is removed. But it is not sent to the clipboard. When I cut and paste, the text I get is what was previously in the clipboard.

What could be the cause? How can I debug this problem?

PROBLEM: After a restart of Windows 10 and re-starting Firefox, a Firefox window with a YouTube web page in a tab will start playing unbidden. When multiple Firefox windows with multiple tabs each are in use multiple YouTube videos will start playing. (Only one of possibly multiple YouTube tabs per FireFox window, I believe.) The cacaphony is annoying. Tracking down the offending tabs is difficult. (There is no "Show tabs playing media" feature in Firefox.)

QUESTIONS: (1) How do I prevent Firefox from playing media (YouTube and others) unbidden when Firefox re-starts and re-loads its tabs? (2) How do I quickly find which Firefox windows have a tab that is playing media? (3) How do I quickly find which Firefox tabs are playing media? (4) How can YouTube videos be prevented from automatically starting when a Firefox web page with that video is re-loaded?

I just noticed after an update today that the Mobile menu entry (with bookmarks from my mobile Firefox instances) no longer appears in the browser's Bookmarks menu. I can access them from the bookmark manager, but this change seems extraordinarily stupid and arbitrary and is a definite step backwards.

After my Windows 10 laptop being in sleep mode I found my background picture changed and all my Firefox tabs missing (while my bookmarks, add-ons, history etc. saved, and all other apps functioning properly). Recently Closed Windows menu was inactive and using Restore option in Library had no effect (despite availability of recent saves).

I found out that Mozilla folder was just missing in %appdata% (e.g. Profile Folder in about:support leaded to a non-existent directory). No manual changes to Firefox settings/data were made and no new profiles created.

What might be the problem and are there any ways to restore my tabs?

Even though my laptop, tablet, phone and PC have the language settings set to English (GB) my Firefox across all platforms has changed from displaying English results to displaying results in French. I have gone through and changed all my language settings in and outside of the browser from English (Canada), to English (GB) to no avail. It still shows up in French. and I have had an French to English translator popping up when searching in Firefox. I can't see anywhere else to change the language. Everywhere I see, it says English (GB), but still displays French headings to the searchs. Any help will be great. Thanks.

Firefox does not allow me to post comments on New York Post. The comment section says I must log in to post, but I am already logged in. I can log out and log back in again, but still not allowed to post as it says I need to log in. When I change browsers there is no difficulty posting after logging in. What setting on Firefox is preventing me from posting on NY Post?
