How do I save my settings when I change them? I really do not like the dark theme but when I try to change it to the light theme it does not seem to recognize my choice when I open Firefox the next time. I also don't like that fact that Firefox does not open on my homepage like it used to. How can I revert to the Firefox I had before it was apparently updated?

How can I change the order of my email accounts? I need to be able to move 1 or more accounts from the bottom of the list to the top of the list. I have Thunderbird 128.6.0

This has been working for days, but now it gives me this (see attached pictures)

This happened once another day but then it auto resolved. What should happen is the plugin would load and be playable in the tab. The plugin is coming from the same site, just a different url. Other plugins work, just not these. It doesn't make any sense because the page doesn't use google at all; that's just the login mechanism for the main page, websim. If I am logged into websim and to google this message should never popup, but it does and it blocks me and other users from using the tabs as intended.

I tried clearing cache, cookies, rebooting, etc. I logged into google, etc.

Any of the GRAST tabs do this: https://websim.ai/@Or9

This uri is the tab that tries to auto load: https://websim.ai/@Or9/m-grast You can find the others in pinned projects. I can access the uri just fine, it doesn't ask for login.

Any ideas on how to fix this? It doesn't seem right that Google can block my use of the plugin because I'm not logged in, even when I am actually logged in. Seems like a bug, probably browser side. Can someone figure this out for us?

Arch/Firefox

Since installing Firefox on Ubuntu 24.04 from the mozillateam-ppa, I can't simply open normal files like .pdf with my preferred OS-application (evince) by clicking the link. Instead a "File Link" handler (see attached image) opens for any such file, be them .pdf, .odt or whatever, and this handler only knows one default and has to be told all possible applications by hand.

How can I configure to Firefox to open any file by the preferred OS-application.

All the messages in my Inbox disappeared this morning. I have a MacBook Air running Sonoma 14.7.2, my ISP is Gandi, and Thunderbird 115.4.1 is my email. I had clicked on a link in an email from a known source and when I returned to email, all the inbox messages were gone. All other folders (Sent, Drafts, etc) are there and current. My husband and I each have email accounts; his Inbox is all there too. The Inbox emails were not in the Trash, Deleted or Junk folders. I closed Thunderbird and reopened; messages still gone. I closed all apps, shut down the computer and restarted; opened Thunderbird, messages still gone. When I look at the Profile files, I can't tell which one would be my Inbox, but none of the likely candidates seems big enough to hold the, um, 7000+ messages that were there. I have spent the day internet-searching and reading various posts on disappearing messages - most of which are very old and/or for Windows - but I am unable to figure out what to do. Are the messages somewhere in the Profile? Are they on my ISP's server? How can I get them back into the Inbox? Thanks for any help.

Firefox detected an issue and did not continue to www.ndl.ethernet.edu.et. The website is either misconfigured or your computer clock is set to the wrong time.

It’s likely the website’s certificate is expired, which prevents Firefox from connecting securely. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Hi- I'm trying to setup two step in Microsoft Authenticator. I scan in the QR code from the Mozilla settings and that appears to work. However when I copy the generated code from the app and try to enter it back into the settings in my browser it tells me the code is wrong and thus I can't setup two step. I've tried loads of different authenticator apps and none seem to work. Can you help please? Thanks- Adrian.

I've used Firefox for many years. The past month or so weather radar doesn't come up on multiple weather sites, pages are slow to load or don't load, getting error codes on video's, pictures don't always load, and many other problems. I uninstalled Firefox and re-installed the current browser and I still have all these problems. I'm having to use another browser now. I run Windows 11 on my PC.

I have noticed that just recently videos across all different websites are not displaying properly. The image part of the video is a green scrambled mess. The audio is fine, but the images are wrong. I am not having this issue on a different browser, and I'm not sure what I'm supposed to do. I don't know if changing any of the settings will help or if there's a bug in one of the updates.

Over the last 6 months, and increasing number of websites don't open on Firefox. I've noticed it most consistently on any of the wikipedia/wikimedia pages, but it's not just those. When I type in an address and press return, or click on a link, the browser just acts as if nothing has happened. There does not show me the loading symbole. If I ask it to open a new tab with the site, the address appears on the tab, but the page itself is just black. Other browsers have no problem loading the same sites. I am on a mac, and using a VPN. Restarting the browser doesn't help, though restarting the computer sometimes does.

Thank you,

few days ago, i was trying to remove unimportant entries from the browsing history section. i discovered that my delete button wasn't working and no entry was being deleted, not even when i was trying to remove using the mouse right side button. at first, i thought the delete button of the keyboard has become faulty. but i found that it was working fine in other apps or parts of the Windows OS. so i tried again removing the entries but couldn't do it. then i closed the firefox browser and reopened it. to my horror, i found that all entries before November in the firefox history section have just disappeared. nothing is there. i felt very much shocked and sad because there were lots of important entries which i have stored for almost two years. now i don't know how to restore my lost history entries. just because of some errors in the firefox program, i have lost my long saved entries. please suggest me how to restore it.
