Firefox Support Forum

About four or five days ago my computer will not let me use Firefox to send attachments. Instead, the only way I can send attachments now is via "Microsoft office client virtualization handler" - whatever that is. Is this legit? Did you authorize this? Thanks - Gary Carter - Port Orford Oregon

How do I completely remove all traces of Firefox from my windows 10 OS? Note: This is why, After windows ask me to run your application or program or software, and I click the yes button after I had done that it doesn't do anything after that and then it just repeatedly does this, and I had used windows uninstall program and I uninstall Firefox then I had reinstall it and it still did the same exact thing that I had mentioned above "even tried using the Windows Registry Editor too!"

Note for years I had used your browser and hardly had any troubles with or problems with your browser

The letters in words are not uniform, one side, top or bottom is dark and the other is light. It makes it very hard to read. I've tried to copy something to show but can't. Even in what I'm typing here now I can see the difference. Like the p in copy is dark on one side and the other is light. This has happened before, but I can't seem to find or remember what I was told to do to fix it. The "e" had a dark straight line and the "c" part is light Very frustrating!

Hi everybody! This new function "picture in picture" is bothering and prenvents from concentrating on the main subject. I tried everything announced to stop it including menu > options > deactivate control... but it still invites itself, no possible control. How may I stop that completely??? tks Lionel

Hi! I recently reset Firefox on my iMac, which restored it to default settings. But now, although I'm signed in to Firefox on my Macbook laptop and my Android phone, logins and passwords aren't syncing to the iMac. They're all on the same network, inches apart, and the two computers are otherwise synced (both running Catalina 10.15.7). I've tried the "Sync Now" button in Firefox, but it's not helping. Any suggestions? Thanks!

I set the default search engine as Google but it's being redirected to Yahoo. Fix I read states to use: help, troubleshooting information, refresh Firefox (in a pop up window). Pop up window never shows. What's the fix? This is supposedly a virus. Not Yahoo's fault. thanks

Bad code on recent Beta download- XML Parsing Error: undefined entity Location: chrome://browser/content/browser.xhtml Line Number 746, Column 15:

I'd like to hide the title bar in Firefox. It takes up valuable on-screen real-estate, and doesn't really serve a purpose (other than showing a web page's full title, which I'm not interested in anyway).

In this screenshot, I have Firefox on the left, and Brave on the right. Now, I know it's only about 30 or so vertical pixels, but the title bar in Firefox is taking up a lot of space that could be used for actual web content.

Is there any way to disable this top bar? Or is it baked into the actual program itself?

I installed the windows update for Windows 10 20H2, and I'm getting graphical artifacts on websites and firefox home page.

This can be see on google maps while moving around the map.

Tried on Microsoft edge and didn't happen

Is there an ETA to fix this?

My Firefox version is 83.0b2 (64-bit).

And I'm on the latest drivers for my graphics card.

Hi,

So the default paper size for the printer keeps on defaulting to letter. When we require A4.

In previous versions this could be fixed by changing paper_data to 9.

However on the latest version of Firefox this option is no longer there. Instead it is replaced with print_paper_id. I have tried different values and this will not work.

Any ideas on how we can get this to default to A4 as the paper size?

Thanks.

Браузер постоянно крашится не зависимо от дополнений, уже пробовал переустанавливать и полностью удалять данные браузера. Всё началось после последнего обновления Windows (на данный момент до Windows 10, v2004, OS build 19041.572) и Firefox (до 82.0). Первое время после падения открывалась Кортана, чтобы она не мешала прописал в реестре запрет на её запуск.

For example, lets say i try to login into https://forum.paradoxplaza.com/forum/ . When i enter my login/password it shows me a blank page and then nothing afterwards. This happens to me on quite a lot of sites, like https://www.gosuslugi.ru/ for example, which does the same thing, for payments on some delivery sites (like https://www.delivery-club.ru/spb) and such. It does not happen in other browsers, like IE for example.

This is a pretty weird problem. When I go to download a PDF from our company's website, Firefox is asking if I want to open it or download it, and here is what happens with both options:

• Open -- It identifies the document as HTML and presents the raw PDF data (it becomes file.pdf.html)
• Download -- It downloads the file correctly as a pdf, and calls it file.pdf. The file can then be opened and correctly rendered as a PDF.

I'm assuming it is an issue with the response header-- either it is malformed or non-standard, or maybe it is just Firefox being wonky. IE, Edge, and Chrome have no problem with it.

The mime type is application/pdf, and we are using a Content-disposition: attachment; filename="file.pdf".

Hopefully this is an easy issue to fix, but this is out of my normal realm of programming. The Firefox users where I work know to download the offending files instead of immediately opening them, it would just be nice to actually fix the issue.

Oh, in case it helps, part of the HTTP response header that we are sending is telling the browser to treat the file like an attachment, so the other browsers just save it.

Thanks for any insight and help!

After update to firefox 80 sometimes random pages do not load. They open as blank white page with refresh button being inactive. Only way to solve this problem is close page, open new tab and try to load this page again.

This is completely random, happening on all sites, opened from links on other sites, bookmarks or speed dial. No idea what could cause it. Maybe firefox has some problems with creating new process for new tab if my process limit is set to 1?
