Is there a setting or add-on for firefox (Windows) that will block tracking pixels? My email client hi-lites when present and as I understand they are incorporated within images so I dont down load attached images to reduce them. On their pro version they allow blocking of these pixels. Unlike cookies there doesn't seem to be an option on reception to opt out. I'm not fully clear what harm they do or whether they are session use only and delete on power off. I would rather not recieve them atall. Companies when challenged smokescreen and refer to cookies rather than pixels or bang on about their companys integrity.

Thanks for your help

I am running Firefox v 120.0 (64bit) on Windows 10 Pro version 22H2 OS build 19045.3570 and today Firefox has stopped playing the video track on youtube videos or any video that is embedded in a page. Audio works but the screen just shows a blank field of green. The progress bar will show frames from the video. IF I run Firefox in trouble shooting mode the videos play as normal with video and audio tracks.

I have already refreshed fire fox and uninstalled and reinstalled it but the video track is still a blank field of green in both full screen and small screen modes.

Anyone have any ideas on what configuration setting may be causing this? Thanks in advance, Brocky

What has happened to typing and viewing the content of the search INSIDE the Google search box? Why this does not work now and the search moves to the address bar where it is tight and one cannot see all content of the search? Why have you done this? How can I bring it back please? I hate is as is now.

Hello, I've got two profiles, 'Home' and 'Work'. I run two Firefox windows with these profiles. Now, I want to open a link from another application, like Slack or terminal, and want it to be opened in some predictable Firefox window. Now it depends, probably, on which Firefox window I opened last. So I want to be able to select in which window the links should be opened: I see it as marking a window as the default one. Note, that I don't want to set a default account, as there's no default account for me, I always choose which account to use when opening Firefox.

Thanks.

Chrome is fine.

I set the browser to Open previous windows and tabs at restart, on General settings, but it always opens blanc, not saving any tab from the previous session.

How can I correct this issue, if it is one, please?

Coming over from Chrome (I know, I know) and so far the only customization option I'm missing is:

I'd like to be able to see the page number in the sidebar on the left (ideally next to/under each page) when printing a PDF. I work with a lot of downloaded PDFs and I frequently need to break those down into separate documents, which I do by printing to PDF in-browser using custom page ranges. For example, I'll print pages 1-2 to Document1, pages 3-6 to Document 2, and pages 8-10 to Document 3.

Having the current page number at the top of the sidebar isn't very helpful, I want to be able to see the page number for each individual page all the time so I can tell at a glance, for example, that page 7 is blank and can be skipped, or page 6 ends a report so I know which pages get printed together.

Is there a way to set this up?

As Firefox was acting up I was going to uninstall and reinstall. It was suggested that I "refresh" it instead. Following that "refresh" my tabs bar is missing. How do I get it back? Also now the address bar is below the bookmarks bar. I can live with that but I need the tabs bar. FFOX 120.0.1 on Windows 11

I can sign into YouTube ok, and the pictures of the video's are ok, but whatever I try to watch I get a green screen and just the video sound? It started happening yesterday. I am getting fed up with YouTube and the issues it has with Firefox. I'm having to use Microsoft Edge to watch videos. I've done the 3 resets it says on the support page, but still have the issue. Many thanks for getting back to me.

The puzzle piece icon is not on the toolbar. Neither is it shown in the customize toolbar dialog. I have reset the toolbar to default, rebooted Windows 11 and removed & reinstalled Firefox 120.0.1 (64 bit). Those did not work. How can I restore the puzzle piece icon to the toolbar?

I don't remember with which version of Firefox for Linux this issue started; but I cannot play multiple videos at once. If I open two tabs with video sources one of the videos will automatically pause if I start watching the second one.

I have tried disabling my add-ons but the issue persists and I don't think there should be any reason for any of them interfering with videos.

Hey,

I've been having an odd issue with Firefox where tabs where I attempt to access youtube.com will immediately crash. This issue first arose when I attempted to log in to Youtube, and had never occurred before. When I did that login, the tab crashed, and I have been unable to access the website since (100% crash rate).

Basic details: The website does not visually load at all. However, the URL bar icons for the website do briefly appear prior to tab crash. (Autoplay button, etc). The crash is never reported in about:crashes.

I've tried the following tests, unsuccessfully: - Logging out of all Google accounts separately - Disabling all extensions - Transferring all of my data to a new computer - Reinstalling Firefox - Rebooting Firefox in troubleshooting mode

This problem does not occur on my Windows machine but occurred on my previous intel-based Mac and now on my current Apple Silicon Mac.

The only success I have had is in creating an entirely new Firefox profile. However, I would prefer to fix the issue, as I assume that porting all my settings to the new profile would... also probably bring the bug along.

Thanks for reading & any advice is appreciated.

For some reason Montserrat fonts ignore font-weight for me on all websites. In happens on my main browser profile, with a new clean one with no add-ons and even in Tor Browser. Pictures 1 and 2 illustrate the problem. If i go into page inspector and replace "font-family: 'Montserrat', sans-serif;" with "font-family: 'Segoe UI';" the parameter works as expected and the alternative font is rendered properly.

Reinstalling fonts from fontsource.org didn't help.

Every time I am trying to search, google is always pinned on my search bar, and I want to get rid of it. How can I remove google? (On the image I marked the issue with a red circle)

After the most recent update, Firefox often takes 30 seconds or longer to load pages. This behavior began yesterday and has continued today. This isn't the first time this has happened. Solutions?

I'm using a new PC with Windows 11 and find that I, inadvertently close Firefox with 16-20 open tabs. Most of the time when I reopen FF, the tabs are still there, as expected. Sometimes, the browser opens with just a new home page and the pinned and other tabs have closed. I can sometimes see the 16ish tabs in history and reopen them. More recently, I find that they are not in history as a number of tabs so I have to set them up again. This rarely happened on my old PC and if it did I would have bookmarked a group of open tabs that I used regularly.

The failsafe FF General setting is as follows: Startup, Open previous windows and tabs.

I don't know how I can stop losing my open Tabs but if I was able to bookmark all the open tabs to be used in case of a problem I would feel more secure.

How do I bookmark ALL or several my open tabs?

Popups for Smithsonian magazine keep appearing, sometimes 2 at a time, despite having popups blocked. I need them to stop. They are annoying and cover up content of web pages.

Got a problem on two separate computers: Mozilla Crash Reporter keeps popping up when Firefox is not even running. I'm guessing that my antivirus avast is interfering with the update service. I'm I right or wrong? Otherwise, does anyone know how to interpret this? This is the report:
