i want to know if there is an addblocker built into firefox and if there is how do i remove it because im pretty sure it's messing with a website i use to watch anime

After removing elements from a website with another add-on, I'm left with a considerable white gap at the top.

I can manually change (pointless) the margin-top property to -100px, but how do I do this with the Stylus add-on?

Stylus doesn't like negative values:

margin-top -100px

10:20 Expected "{" but found "-100px".

Is there a lighter/simpler alternative to Stylus?

just happened today....only the AARP website is not using my browser Zoom setting of 120% it is using browser Zoom setting of 160% which is too large....I reset it on each page but it wont stay at my browser Zoom setting of 120% this happened a year or so ago....cant remember the solution

When I play a video in fullscreen, there is a strange black border that appears around the video which makes the content smaller than it would otherwise be. This border does not display in Safari or Chrome, just in Firefox. It also occurs in every media player I've tested, including YouTube and Netflix.

Annoyingly, I can't get this to show up in a screenshot. It seems like Firefox guesses the aspect ratio or resolution wrong when it puts media in fullscreen, and it has the effect of downsizing the actual interactive part of the display. Meaning, I can't move my mouse into the border area to take a screenshot of it.

I'm on an ARM Macbook running MacOS 13.5, if that matters.

Is this a bug, and/or is there a way to fix this?

trying to open 3d model on this site https://teemo.gg/viewer/league-of-legends/champions/katarina/0 its start loaded model but nothing was showed in browsers based on chromium everything works fine

I am currently fresh on Fedora 38 and Firefox 115 with multimedia codecs installed such as ffmpeg. I have problems playing videos on Facebook or Twitch, like in myday stories, reels, and feed. But in YouTube, videos plays perfectly so I think there is a bug going on here? I already tested turning hardware acceleration on and off but no avail.

No matter what I try, I can't allow any sites to present my screen or a window, I can't find an option in settings neither in the option to allow in the tab. The "allow" button is simply not available at all. How do I solve that? The problem happens in all sites that I've tried: focusmate, cofocus, discord, google meet, etc

I had something like 7 windows open 10 minutes ago (yes I am a tab hoarder). I was trying to run a game that used a lot of RAM, so I decided that I would close ALL of my firefox tabs in hope that the game would run smoother with the 5gb that Firefox was using. I didn't think anything of losing the tabs because I had accidentally closed windows in the past using the big red 'x', and an easy ctrl + shift + t always restored the entire window no problem. When I tried to open firefox again within the next 5 minutes, only 3 of the windows restored themselves, I assume using the general > startup > open previous windows and tabs setting. Using Ctrl + Shift + T did nothing to restore them. Please help, as the windows that did reopen were the ones that I cared the least about.

I download a file. It stops and speaks of a security risk. The website is https, but the file is http. Is there a location I can pre-approve all files from the url to override the objection? Thanks.

Firefox is displaying a smaller font on some websites. It only does it new windows, not in a private window and other browsers are fine.

Screenshots attached show the correct size (first attachment) and the incorrect smaller size (second attachment).

It's not windows accessibility aka ease of access, as nothing else is affected. All pages are on 100% zoom. I've gone to settings -> font -> advanced and the "Allow pages to choose their own fonts, instead of your selections above" is ticked.

Any ideas please?

other menus like the pop-up bookmark list menu is fine. i only have this problem with the download menu and the bookmarking menu. i only remember this happening after i started to tweak and customize my windows 11 os, so maybe something in that process happened to break the text now but i have no idea where to look. i have cleared the startup cache, refreshed firefox and even uninstall/reinstalled it completely fresh (this is also what made me believe this is an os problem).

When enabling the PiP player window for say a YouTube video from the YouTube website - pressing the 'pause' button on the PiP player window followed by doing any forms of multitasking like opening another window, or opening another program/app or file etc, and then a few seconds later pressing the 'play' button on the PiP player window - it doesn't actually play the video.

You can click the 'play' button over and over and over again but the video in the PiP player window will not play. In order to get the video to play again you have to exit the PiP player window by clicking 'back to tab' and then clicking the 'PiP' icon again.

Using Firefox version 115.0.2

Anyone else experiencing this?

I'm using a video as the background for my website, and Firefox's built-in PIP (Picture-in-Picture) icon for videos is displaying. I don't want it to be visible on my website. I tried using FFmpeg, but it did not work as it was mentioned by some people on Stack Overflow. I read that Firefox won't display this icon for videos in an iframe, but I don't want to use an iframe on my website. Is there any other solution?

I subscribe to The Times (UK) and use many of their different portals. I am, however, experiencing a really odd problem. For the last three Mondays in a row when I hover over a link it shows one destination which is now three weeks out of date and downloads same when clicked. When I Inspect(Q) the relevant bit of script it shows the correct page for the current week. All other links from the current edition work as expected. The link works correctly on other days of the week. The IT support at The Times have no idea why this is happening and have simply asked me to do stupid things like clearing all cache and cookies relevant to their site. this has no effect whatsoever!

How can this happen and have you any help on the subject?

I've been watching and following along with a Unreal Engine 4 Course on Youtube for some time now (mentioning in case the resource usage has something to do with it), and in the past couple days I've noticed a pretty serious and annoying bug. When I pause the video, tab (Cmd + Tab on MacOS) into Unreal Engine, do some things, then tab back and resume the video, it will play for one frame and then stop and buffer, but the audio will continue playing. The only way to get the video to resume is to skip forward/backward in the video (either with the arrow keys or the progress bar). I've also tried Troubleshooting/Safe mode and the issue still persits.

Firefox 115.0b7 is not correctly handling my system timezone, and using GMT instead. This only happens in specific pages, such as when accessing a website, or in `about:home`. It doesn't happen in `about:config` or `about:profiles`, for instance.

`privacy.resistFingerprinting` is set to `false`. The problem persists in Troubleshoot mode. The issue isn't present in Firefox ESR 102.12.0.

Running `date -R` with the system shell: `Sat, 22 Jul 2023 12:10:42 -0300`

Javascript console at `about:config`: ``` > Date() "Sat Jul 22 2023 12:10:42 GMT-0300 (Brasilia Standard Time)" > new Date() Date Sat Jul 22 2023 12:10:42 GMT-0300 (Brasilia Standard Time) > (new Date()).getTimezoneOffset() 180 ```

Javascript console at `about:home` or `https://example.com`: ``` > Date() "Sat Jul 22 2023 15:10:42 GMT+0000 (GMT)" > new Date() Date Sat Jul 22 2023 12:10:42 GMT-0300 (Brasilia Standard Time) > (new Date()).getTimezoneoffset() 0 ```

When I pressed the "+" symbol at the right side of my tabs with the left mouse button, a new tab opens at the most right place. So far, so easy.

When I pressed the same "+" symbol using the middle mouse button, the new tab opened right beside the active tab. Now, middle mouse button and left mouse button do the same thing.

Work around could be to open the context menu (right mouse button) of a tab, choose "new tab" an get a new tab right beside the tab chosen with the mouse pointer while pressing the right mouse button.

Did something recently change?
