What is the story on the VPN, a few weeks ago the previous versions new features banner said you have a new VPN option, my Firefox browser did not show the VPN button, today got a new update to 151.0 with a NEW whats new banner promoting the VPN option and I STILL do not get the VPN button. I checked customize toolbar and the VPN button is not there either.

WHY are you showing this as available when it is not ?

Hi, I’m testing a WordPress website in Firefox and noticed that some recent changes (like text or small layout updates) don’t appear immediately. The site is using Cloudflare CDN and caching, and even after refreshing or clearing cache, the older version sometimes still shows.

Could this be related to Firefox caching behavior? Is there anything specific I should check to make sure updates appear correctly?

Thanks in advance for any help.

Hi, it looks like Firefox can copy links from selected tabs, using right-click menu. It doesn't work for non HTTP(S) addresses though, such as "file:///C:/Users/USER/etc."

Is it possible for non HTTP(S) addresses?

The add on Export Tabs URLs by AL is very good, has the option for non HTTP(S) addresses, but I couldn't get it to work for selected tabs, is it possible for selected tabs?

My question is a very obvious one if you look at the two screenshots I've attached. The 'X' to close the Firefox browser keeps disappearing, along with the 'maximize' and 'minimize' options as well. This has been happening for months. The recurrence rate is 50/50 each time I open the FF browser. It's not just an issue with closing or minimizing a page, it also removes the access to my Windows taskbar at the bottom!! Normally, when I move my mouse to the bottom, my taskbar pops up and I can access whatever I need, BUT when the FF browser has NO 'X' at the top corner, my taskbar won't show up at all! This is finally getting on my last nerve!🤦♀

Any knowledge as to why this keeps happening?🤷♀

My FF browser is up to date, as of yesterday. My default search engine is google. My PC is still running Windows 10.....could this be the problem?

My firefox is on the latest version and up-to-date but will not access my home router which l normally us ip address. When trying to acess in edge works with no issues I am using windows 11 and all ok but wish to use Firefox And the IP adress is corect Can you advise

Clearly, this is a very basic question which has undoubtedly been answered before, but I haven't been able to find it. If Thunderbird had an old-style Help feature with an index, I could probably look it right up. But coming to the forum is the only option the program gives me.

I changed ma mozilla acc password and when i try to log in with new password on mobile "unknown error" occur. I can login on desktop with same password just fine. What to do?

Hello,

I am on Thunderbird 150.0.2 for Windows.

I am really suffering here. I need to change the font weight of unread messages. In a non-threaded list.

The default weight I get with my preferred font (Trebuchet MS) is not bold. It is BLACK. When I say BLACK, I mean ultra bold, display font, heading weight. Heavier than the boldest font that even exists in the font family. Thunderbird is creating this ultra mega black font by taking the bold font variant and applying a faux bold effect to it. The result is that the text is so heavy that it takes up twice as much horizontal space as the ordinary bold font variant. This becomes a usability issue because it's not possible to see the date, sender, and subject at the same time.

I have struggled and strived with userchrome.css. Spent hours combing through forums here and elsewhere. I've already enabled the mystery setting in the config editor. I put userchrome.css where it is supposed to be.

I saw a blog post from Mozilla that says "userchrome.css is not supported". What is the actual meaning of this? That it has been actively blocked from working anymore, ever, for anyone? Or that users are taking risks if they create userchrome.css? Why can't developers speak plain language? "Not supported" could mean many things.

When I go to the Style Editor, userchrome.css does not exist there. Which leads me to believe that user customizations are absolutely deprecated and we are not permitted to use userchrome.css.

I tried editing some of the rules in the Style Editor, but could not determine any way of actually storing the changes. When I click Save, I get a dialog where I can **EXPORT** the file. But I can't seem to actually save the changes, because CSS files do not appear to exist in the installation directory. It must be compiled into some library.

This is extremely unsatisfying and super frustrating. Just getting straight answers to things is super difficult, nothing stays the same for more than a couple months, and up to date information either does not exist or is not found by any search engine.

So, please help. I just need to change one setting, the font weight of unread messages. Since Thunderbird is allegedly open source, I thought I would have some ability to make such changes. But the Style Editor doesn't seem to actually be an editor, but merely a read-only interface to precompiled rules? If I wanted to change the font weight of unread messages, would I be forced to compile my own version of Thunderbird? I'm not competent to do that, and it would probably either prevent updates, or the updates would break my changes.

Please help, I am super desperate. I need to see the date, sender, and subject all at the same time. That doesn't seem like an unreasonable ask.

I would gladly pay for an email client that gives me control over my data *and* allows me to control the UI, but apparently that doesn't exist.

Ever since the latest update, when I hit send for an email. It says it cannot send, I cancel, hit send again and it goes through. I have to try sending EVERY email twice.

I just installed a new router and all of a sudden nothing is working properly on my PC. Among other things, I need to fix Thunderbird, and for that I need to find where my thunderbird profile is. The instructions I've seen say to go to troubleshooting information, find profile folder, and click on "open folder." When I do that, nothing happens. (I told you installing the router appears to have broken everything--I don't know how that happened, especially since I was on the phone with tech support for the router for install), and I'm no closer to finding the profile file. I can enter %appdata%\roaming\thunderbird\profiles but that shows me two different profile directories and I don't know which one is the right one. How can I find the correct file and why doesn't troubleshooting information just show me that?

This only recently started happening. This has been tested on 3 different computers. Windows 10 Pro on all three.

With VPN on: Bluemail works fine.

Thunderbird can connect and download messages, but when I try to send a message, it gives an error.

With VPN off:

Bluemail and Thunderbird both work fine.

Drgan Maric, 74, Belgrade, Serbia. This is my self-taught English.

I use Thunderbirad for years, including small donation when I start to use it. Since a few days I can not open WebMail from cPanel of Namecheap,

Nothing is changed in both servers and ports. In Account Settings Outgoing Server has an option to TEST connection for server. Result failed.

An Attachment is an immage of TEST and RESULT FILED.

In this age, with broken spine and almost immovanle, it makes me very frustrated. Coud you plase reaolve this issue and make Thunderbird to work properly and peace in my mind,

I already left a topic here on this issue, then no one could help me, in general, the problem appeared a month ago in me, as after I reinstalled Windows, downloaded the facit anti-cheat steam browser and went to play facit, since facit requires some settings in the bios for it to work, when downloading the anti-cheat, it asks to restart the computer, it asks for tpm 2.0 secure boot , VBS , iommu , and so I thought for a long time what could be the problem that it is after installing the anti-cheat facit that the browser breaks. As a result, I found out that it is when the iommu function is enabled in the firefox bios that it breaks , if you disable this setting, the browser works, although it gave an error before and did not start at all, I spent a month trying to figure out what the problem was, I am a Windows optimizer and I had custom windows and a lot of different settings for optimizing windows, but now I have installed official windows and the problem is still there, it turned out that it is far from in windows and windows optimization, because I have many friends who use custom windows and optimization settings and everything works for them, and so I found out that it's about iommu , just a couple of days ago, I updated the bios, I had the old version, now the newest one is still present, if there is, then help me figure it out.

here is the error code from the "details" by the way, not only firefox breaks, but also chrome, brave, etc.

what it says on the tin. went data purging with ol reliable WinDirStat and found this absolute behemoth of a file in the profiles directory for firefox. its especially weird considering the entire Firefox directory itself is only 1.5GB with this menace taking 1.3 of it. I cant imagine that bookmarks, search history, passwords, the works takes up any more than about 300mb. so im wondering if im just stuck in the early days of data or if the file really is just that girthy.

Hello all,

I am currently testing the new VPN feature in Firefox. I Is noticed that Firefox always starts with this integrated VPN being off. I searched but I didn't find any way to have it always on when launching VPN. Is that possible?

Thanks!

I'm using Thunderbird 149.02 to make a local copy of all folders, messages and attachments on my yahoo mail account. I don't yet see an obvious way to issue a command to Thunderbird to accomplish this.

I'm using export.imap.mail.yahoo.com as the IMAP server as some of the folders have >10000 messages (none have >100000 messages, and there is no significant real-time email arriving to the account while I do this procedure.)

In settings/offline settings I have "automatically follow detected online state" and "download messages for offline use when going offline [yes].

In account settings/synchronization & storage I have Disk space: Synchronize all messages locally regardless of age"; "to recover disk space, old messages can be permanently deleted..." I have "Don't delete any messages" and "Always keep starred messages"

With these settings, I've tried (from the main menu) File -> Offline > Download/Sync now, then "Download and/or sync..." I have selected Mail Messages, and the Select button takes me to a table where I have selected the main account folder and all sub-folders.

With these settings, Thunderbird appears to go through some of the folders and downloads messages from, them, and after a while says there are no new messages (I don't have the specific text, but it ceases interacting with the server". If I repeat the Download/Sync now procedure, it appears to download more messages, will continue for a while, then stop in the same way.

When I compare the size of Thunderbird's local account folder, it appears to grow after each of these iterations, but is (after half dozen cycles through this) has only reached about 2/3 of the total stoage size reported by Yahoo. While I understand the storage mechanisms would differ significantly between yahoo and Thunderbird, I don't believe I've found a single sure-fire way to accomplish what I set out to do in the first place (which is get a complete copy, through IMAP, of all emails, folders and attachments.

What am I missing?

Thanks,

Dave
