hej, you write oh dear, no print is possible :-((( but you write to me, that I have win10... but it is a new machine with win 11...and firefox does not work, i cant se my mails?!?!!?

I keep getting a pop-up for"sign documents online" in my Firefox browser. Several others have reported the same. It overlays the browser content so I can't use Firefox at all. My only option seems to be to uninstall Firefox and use a different browser. Is there a fix?

Hi, I just installed the latest update (I think it's 136.0.2). I guess I skipped some/several versions. Suddenly my main menu isn't workin anymore (clicking it with the mouse, that is) There is some overlay which I can't find out, how to remove. Even the Minimize/Maximize/Close buttons don't have any function. Luckily I can still access the menu via keyboard shortcuts. How can I remove that overlay bar ... or did I catch some malware ?

Since the new "feature" profiles came out, I now always have this "originalprofile" in the browser (in the title bar) and in the Windows taskbar... It's really annoying.... Now my question is, how do I get rid of it again... on 3 more pictures, Firefox language is German...

When working hints on Ancestry.com, under certain conditions a second scrollbar is generated to the immediate left of the right hand scrollbar. This second scrollbar is used to move downward in the hint compare area on the right hand side of the open page. When running under Firefox on Windows 11 systems "this second scrollbar is not there"! Everything works fine using any other browsers (EDGE, Chrome, Brave), but not Firefox! Works fine on Windows 10 systems. I have tried this on 3 different Windows 11 computers with the same failed results.

I use Xero accounting software and used to be able to view pdf within the software up until the recent update. Now it just sits with a spinning wheel. I've found that if I change the setting within Firefox to open the pdf within Firefox the issue is fixed in Xero. But then all pdf's open in Firefox instead of the usual Adobe. This breaks other workflows within my organisation as I need to email the pdf straight away when I download it, so my Windows was set with Adobe as the default for opening pdf's but now Firefox has taken that over. There does not appear to be any way to email the pdf from Firefox other than to save it and then find the file and email it from there which is very time consuming. I don't know what has changed in Firefox, but please can you fix it. I see I'm not the only person with this issue.

(Title): VPN is not working on my laptop

(Description):

Hello, I installed a VPN on my laptop, but it is not working. I cannot connect to any servers. I have tried restarting my laptop and reinstalling the VPN, but the problem still exists. How can I fix this issue?

Thank you.

Instructions begin with "Click on the three horizontal lines and select OPTIONS." My updated version of Firefox does not have OPTIONS. Reinstalling Firefox did not solve the problem. In OPTIONS, PDF is supposed to be in the list. Opening a pdf file in Firefox did not cause an edit option to appear.

ver: 134.0.1 Windows 10 Pro I have Firefox set to open filetype PDF in Browser. Normally I use IDM which automatically download PDFs, unless I press ALT key while clicking DOWNLOAD button, then it does not, in order to allow Firefox to handle the PDF.

Firefox presently does nothing. With filetype setting set to Open in Browser, Firefox Does nothing. If settings are set to Ask, it does not ask. The PDF filename appears at bottom of screen momentarily.

ver: 115.19.0esr Windows 7 Utl 7601 The exact same behaviour was also seen on a Windows 7 system running Firefox 115.19.0esr. PDF is also set there to "Open in Firefox". Again, when ALT pressed when clicking Download button, Firefox does nothing.

I have a requirement where instead of showing the 404 error or 503 error on screen, I want to display a blank screen. I have already tried to set the following configs to false -

security.insecure_connection_text.enabled security.insecure_connection_icon.enabled security.insecure_connection_text.pbmode.enabled browser.ssl_override_behavior security.ssl.errorReporting.automatic security.enterprise_roots.enabled security.tls.version.min

Is there anymore steps to do or any userChrome.css script is required.

PS : I cannot use any extension or addon to do that

When loading certain pages (on web application) the motion icon starts and after several seconds it changes to the sand clock icon despite the setting described in 'https://support.mozilla.org/en-US/questions/1303416' being done - ui.prefersReducedMotion set to 'false'. My work is all done in this web app and it is very important to see when data is being uploaded (grey/black dots) and when the page is supposedly being refreshed with updated data being downloaded (blue/green dots). Why is the preference being ignored and how to fix it so you always get the motion?

In previous versions of Firefox (up to version 133), it was possible to automatically trigger printing of a PDF file by loading it into an iframe from a sandboxed iframe and call print. However, starting with version 134, this no longer works.

Is there any other way to automatically trigger the print dialog for a PDF file in Firefox, similar to how it can be done in Chrome/Edge (e.g., by opening the PDF in a new window and directly triggering the print dialog without additional button clicks)?

Installed Firefox on my laptop. Already running on my desktop.

Whenever I try to open a link, I get: Get an app to open this 'microsoft-edge' link

Your PC doesn't have an app that can open this link. Try looking for a compatible app in the Microsoft Store.

Is this Microsofts way of saying "Use Edge?" Can I change settings to make it work?

Is there a way to set a default zoom for the firefox pdf viewer? The Automatic zoom has no toggle, and all pages open up as HUGE and I have to manually choose the zoom %. This is tedious and takes up time as I open many documents a day.

I downloaded a PDF and used Firefox to view the file. I'm trying to find key words in the PDF and I always get phrase not found. As a test I inputted a word I found in the document but find in page stated phrase not found. What am I doing wrong? I remember that I have used that feature in the past and it worked.

Hello. Firefox has disabled my Bitwarden, which has all my passwords etc. I really need my bitwarden to work. Can anyone assist me to get the add-on working again? I would really appreciate it. Please see attached graphics. Regards Lana

Over the past couple weeks of updates, the about:processes page is now missing several elements, such as the memory usage, CPU usage, and the close (X) button for each process/tab. See attached screenshot. Normally each row would show the memory, cpu, and if it's a closeable tab, the X button would be on the far right upon hover.

Let me know what other info you need to squash this bug. Thank you!
