I have a 100% repro rate of Firefox redirecting linkedin.com to linkedin.cn. Unfortunately there's another problem beyond the unwanted redirection: linkedin.cn no longer exits, it has been dead for years, I literally cannot reach LinkedIn at all. It was working fine a week or two ago. How do I prevent Firefox from redirecting behind my back? I see the status message (is that what it's called) in the lower left corner "Performing TLS handshake to www.linkedin.cn" and of course it only times out. I just verified with "Web" (different browser), it connects just fine, which suggests that it's a Firefox issue, not a system wide one.

I have just moved from an old laptop to a newer one - a Lenovo Thinkpad. I have installed Linux Mint and successfully transferred my files and Thunderbird. I also synchronized Firefox and all my add-ons, bookmarks and history came across perfectly. While setting up the toolbar from the customise screen I dragged the home page button onto the toolbar and it just disappeared. The home page is set up in settings. It appears the first time I open a window. I would like to be able to go back to my home page at will, how can I re-instate the home page button?

In my nightly broswer Codeberg opens once when I click to go to a repository the tab keeps loading and does not stop and can't accesss anything then. In Firefox I don't have that problem at all only in Nightly then in Nightly my Facebook emoji's does not show but again in Firefox it does.

I'm writing a home-grown email client (Python email module, yay!), and I've received an email with a couple of images with Content-ID: fields. Sure enough, the HTML bears corresponding URLS with cid: schema. Where do I put those image files so FireFox can read them, and when I run FIreFox, how do I tell it where those files are?I'm writing a home-grown email client (Python email module, yay!), and I've received an email with a couple of images with Content-ID: fields.

So I replied to a post on the forum and I got Congrats on your first forum reply! from notifications@support.mozilla.org signed by kpapadea from Mozilla Support

So why? You see I have asked questions before..... I have replied before...... It occurs to me that if Mozilla is using Gmail as their sender then perhaps this is a good way for Google to extract information about me.

Perhaps i am somewhat cynical and Mozilla is just trying to be nice...... I have used Firefox it seems like forever.......from Netscape navigator through all the iterations to the present apparent converging on the layout/format with those other browsers. Is this going to be another Thunderbird moment where decisions made about the formatting just happened to follow Gmail & Outlook....well I no longer use Thunderbird, so perhaps its time to say goodbye to Firefox.

Helium, Ungoogled Chrome, Kagi.....time to start looking and testing

The new "Copy Link to Highlight" button shifted the "search with" option down, which I use regularly.

I'm not entirely sure what the new option does, but I would like to either disable it or shift it further down out of the way

On Arch Linux with the latest version of Firefox, the interface elements turn black due to a theme loading failure. 'This issue persists even when using the default theme.

Going to Settings and disabling the theme (which automatically falls back to another theme) resolves the problem.Re‑enabling the problematic theme does not reproduce it immediately. However, the issue reappears after restarting Firefox.

Hi everyone,

I am currently using Firefox on Fedora (KDE Plasma) and looking for a way to automatically route downloaded files into specific folders based on their file extensions.

For example, if I download a '.stl' or '.blend' file, I want it to automatically go to '~/3d/downloaded', and if it is a '.gguf' file, it should go to '/models'.

Since native application settings only allow choosing one global download folder, using third-party browser extensions feels like a security risk as they require broad file system access(This concern might be unnecessary since I don't know how to decide an extension is safe or not.). On the other hand, running a background automation script (like inotify-tools) feels like an unnecessary workaround for a feature that could be native(I solved it via this method for now).

Is there a built-in way or a hidden config in about:config to achieve this by file type? If not, do you think it is worth opening a feature request on Mozilla Bugzilla for native file-extension-based download routing?

I am using Firefox on Linux Ubuntu 26.04. I normally work with multiple tabs. Then I quit Firefox with all tabs open at the point of quitting. Some times on the rare occasion there can be a forced quit due to some issues. In my settings I have configured it not to open the previous tabs. In fact I want a blank page. But whenever I reopen Firefox, it opens those tabs and tries to reload which is annoying. Some of these pages take a long time to reload, and why would I want to look at tabs which I already have read. Or if it crashes due to some website on a tab why reopen something that crashed in the place ? Can you fix this. Thanks.

I have to reload history, bookmarks, passwords each 3 - 4 days, when Firefox refreshes the software. It was not happening before, just in the last two moths. How can I fix it?

I'm using Firefox from the official Ubuntu repository (packages.mozilla.org). I have used the (very cool) "translate page" feature successfully, but for some reason it doesn't seem to work on https://wiki.openstreetmap.org/wiki/NL:Basisregistratie_Adressen_en_Gebouwen which I'd like translated to English. Even though Firefox thinks the page was translated, only one of the headings seems to be in English.

I would like to understand how to troubleshoot this and help you improve this great feature. Thank you in advance.

Good day, folks!

I mistakenly posted this query to the Thunderbird forum. It is a Firefox extension issue. [Sigh]

For over a week, the WIKI2 extension has not been working in Firefox on Linux Mint 22.3. "Normal" operation (when it's working) is for a link clicked to a Wikipedia page to be automatically re-directed to the WIKI2 rendering of that page. This no longer happens.

Further, I receive this when trying to access their web site: Sorry, you have been blocked You are unable to access wiki2.org

Experience has taught me, when something that has been working flawlessly suddenly stops working, to ask, "Is it me, or is it you?" I'm not about to start twisting dials to fix a problem that is on their end.

Has anyone here experienced this same recent behavior with the WIKI2 extension?

If so, I'll leave it alone until the problem is fixed on their site.

Thanks in advance,

- Ralph

My Firefox browser (nightly snap 154.0a1 on Ubuntu 24.04) has been misbehaving lately (~2 weeks now) and I'm at a loss why.

First, when I scroll using the mouse wheel, the scrollbar continuously shoots back to the top constantly during scrolling.

Second, when I type text in a Google box and hit enter key, it drops to the next line - like one would expect in a text processing application.

Third, when on YouTube, trying to rewind/forward video instead starts navigating to clickable links. Of particular note (see the attached screenshots) is the appearance of text (such as "Skip navigation" and "Volume" to name a few) - something I've never seen before.

This happens with a new profile as well.

Now, I know that nightly will sometimes have broken items but this is a weird one. I at one time thought the batteries on my wireless keyboard could be responsible but new batteries (confirmed new with a digital multimeter) did not change that.

I'm on Ubuntu 24.04 LTS fully patched. Anyone here with ideas on what it might be?

On Ununtu 24.04 I did an update and youtube doesn't work on FIrefox 152.0.4. I did an update from the Software updater and videos don't play on youtube any more. I go to youtube, click on a suggested video and it goes to that page and everything shows up except the video window. I have the title and the comments and the row of suggested videos on the right, but no video player and no video. Someone suggested I push the F12 key and look under console and there is an error there, a sourcemap error and that it isn't a valid URL . I don't know what that means. I asked on the AskUbuntu site but they get really far down in the weeds and I have no idea what they are asking or saying. I thought I'd see if you guys might know. thanks

When will the mozilla vpn available for linux? I've been using mozilla for a long time, I tried to connect to different vpns but non of them worked. Some sites that I have to work on needs vpn but I can't connect to any of the vpn extensions on mozilla and due to this reason I am not able to do my work. So please make it available as soon as possible.
