bold text So I get the latest update to Firefox this morning, open a new tab, and all the tiles I had arraigned the way I wanted them no longer in that order, some are missing, some are duplicated 2-3 times. Why can't you guys quit with the window dressing BS and just make the browser stable. Why do we need to hunt for functions that were the same for many years that you decided needed to be changed? I remember when 'Settings' was on the new tab window instead of on the drop down menu in the tool bar.

My new tab tiles are a mess and I don't think I'll ever forgive you for that!

I'm using firefox in ubuntu. A couple of minutes ago Firefox crashed. I restarted to a completely new Firefox. All my tabs, extensions, saved passwords, etc. were gone. This happened to me a few weeks ago. That time I found a solution: find a back-up of the old profile and manually restore it. I tried to reproduce that solution this time, only to find that there are no back-ups at all of my previous session. Is there a solution to this problem?

I use vertical view. Hate threading so that's turned off. I use a medium to large message pane. Recently been having issues with column visibility. Not sure if this is new or whether it's that I've come to a Linux client from a Windows one and there's a setting I missed when I set up the client.

Essentially dragging the column divider doesn't work properly (for me). The columns always seem to auto adjust width. Similarly if I resize the message pane the columns don't remain fixed they auto adjust.

I don't find this helpful. I prefer to set up the columns to display the amount I want/need in subject and From and I truncate the date to simply not display time.

How do I set column widths to remain where I put them? Or is this function now lost.

The Alt-<number> keyboard shortcut is used to switch between tabs. However, the key event used to switch a tab seems to also propagate down to the content itself. This creates weird interactions:

- I switch to third tab - The web page running in the third tab actually uses Alt-3 to do something - After switching tabs the web page does something unexpected because the browser chrome didn't swallow the event during its tab-switching procedure.

The most irritating candidate seems to be XenForo forum software that uses Alt-<number> to go to different sections in its menubar. For example, alt-4 seems to open a search page and going there provides no new entry in the browser history. So, if I've tab-opened the forum to display new posts and then later I switch to it using Alt-4, it makes the content go to its search panel with no way to go back to new posts. Ironically, switching _away_ from the tab 4 does not register to the content so I can't even use the forum's own keyboard shortcuts to navigate back to new posts section or any other section. Having the forum in tab X will only ever let the forum see Alt-X and nothing else.

This all stems from the fact that Firefox lets the initial tab-switching key event through whereas I think it shouldn't. It maybe should if the corresponding tab is already active but it certainly shouldn't when a tab-switch actually occurs.

I've obviously disabled the content's capability to override keyboard shortcuts but it doesn't help in this because the content is not overriding anything: it seems to be just listening to a keyboard event that it shouldn't see.

Did I miss some option in about:config or do others see this as well?

I wanted to use the Firefox browser VPN to check what the price of a certain Patreon subscription is in another country, but when the VPN is on, the website still correctly identifies my current location and shows me the price in my current country's currency. Is this a limitation of the VPN, or did I not set it up correctly?

Does Firefox VPN not work with DNS over HTTPS set to Max Protection, and when using a custom provider?

With the VPN on and DNS over HTTPS set to Max Protection set to custom provider, no pages will load and I get an error screen/can't connect to proxy screen.

I am using Linux mint and have never encountered this problem before. It is not a login or password problem! I can't even open the site to get to that part! Connection timed out. Is there a simple fix like allowing AI enhancements? I found disabling them solved my shut down lag time and load time. I wonder what other sites won't work now.

Hello all

 Firstly I have been using Firefox for about 2 decades and it has always worked perfectly - you can take a bow.
Now for my problem
I have been using Firefox for internet banking for many years without any problems - the usual login, password ans secret questions. Just after Xmas my bank updated it's website and suddenly nothing works. I was told that it now only works on Chrome and NOTHING else - not Firefox, Edge or anything else. I am able to log-in but can't see my account balances or perform any other functions - it just jams up to the point that I even have trouble closing Firefox.
I use Firefox exclusively because I don't trust Chrome or Google - they are just a massive data collection/sharing operation. I have Chrome Mask installed but it just doesn't make any difference.

 Is there anything that I can do or add-on to over-ride this problem?

I am running Mint Linux 22.2 with Firefox 151.0.1

I recently obtained a digital certificate for use with S/MIME. I followed the process laid out in

https://support.mozilla.org/en-US/kb/instructions-smime-certificate-using-csr

to generate my key pair, create a CSR, submit it to a CA, download the resulting certificate file, and import it into Thunderbird. I also imported the intermediate certificate showed as the issuer for my cert, which in turn appears to be signed by one of the certs trusted by default in Thunderbird.

Having done that, I see the certificate showing up under "your certificates" in the Certificate Manager, with a "not before" date in the past and a "not after" date in the future. So everything appears to look correct, but when I try to send a signed email I get the following error message as a pop-up:

"Sending of the message failed. You specified that this message should be digitally signed, but the application either failed to find the signing certificate specified in your Mail & Newsgroup Account Settings, or the certificate has expired."

And if I look at the console in developer tools I see:

"mailnews.send: NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIMsgComposeSecure.beginCryptoEncapsulation]

I can't make sense of the error message, since the certificate appears under "your certificates" in the certificate manager, and it does not appear to be expired. Can anyone suggest how to determine the root cause and fix it? Does it matter that the certificate is for a non-default identify I've added for the account in Thunderbird? Does it matter if the "common name" in the certificate doesn't match the "Your Name" field in Thunderbird? Any pointers on what to check would be appreciated.

When I receive a junk email, it spends a brief time in my inbox before being moved to the spam folder by the automatic classifier of Thunderbird. In that brief window, the notification system already displays the notification. I found no way of changing that behavior. Is this normal behavior? How to change it?

I am using Kubuntu 26.04 and I am using the monthly stable channel version of the Thunderbird Snap. In KDE system settings, the default email client is set to Thunderbird. Upon every startup of Thunderbird, it ask if I want to set it as the default client for email, newsgroups, feeds and calendar and when I click yes and close Thunderbird and reopen it it does the same thing, over and over. Otherwise the email program operates just fine otherwise. My email accounts are all setup properly and functioning and working and it downloads email just fine. It just has that annoying popup upon every startup. I've included two images to show what I mean. I like the Snap version and prefer that container format. I would like someone who is smarter than me to file a bug on my behalf.

Since a few days, there seems to be an italicized copy of each folder in my mailbox. I tried multiple times to delete them, but, although they seem deleted, they appear again when I start up Thunderbird. I already contacted the hosting service, but they replied that this is an issue of Thunderbird.

I'm a beta update channel user, so this may not reflect what 'normal' users are seeing. I use Firefox in Linux, debian v13, so normal people that are using Windows or MacOS also might not see the changes I'm asking about? -- I have no way of knowing.

Anyway: in FF v152.0b6, the "Connection Settings" area seems to have disappeared entirely from the settings menu. I used this area of the settings frequently.

The ability to set proxy still exists in the about:config settings area. In the future, will about:config be the standard place to go for people that want to manually set (or toggle) an http/https proxy?

Thanks for reading, and thanks to all the Volunteers who make this place and Mozilla software function. I use your stuff all day, every day, and my life is better because of it.

With Mozilla Firefox for Linux Mint 150.0 after logging into Chase Bank , when trying to pay off my credit card, I get a message: "It looks like this part of our site is not working right now". However the site works perfectly with Chrome, thus the problem must be with Firefox. I have cleared the Chase cookies and still getting the same result.

Why is Firefox sending me email msg's saying to try the new firefox VPN when It doesn't seem to be available to me? It's not in the upper right corner as they state and it's not in the toolbar either which they also say it's suppose to be in!
