Firefox Support Forum

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 have not been able to connect to www.paperbackswap.com for 2 days using Firefox. I get this message - The page isn’t redirecting properly-An error occurred during a connection to www.paperbackswap.com. This problem can sometimes be caused by disabling or refusing to accept cookies. This is a persistent problem happening every few days. I have sent messages before to PBS and Firefox with no response. I have cleared cookies and added PBS to Firefox as a site to always accept cookies. I can access the site using Chrome but I would prefer Firefox. Is there anything that can be done?

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.

I have a Plesk (apache) server that is behind HAProxy. When I connect securely to a web site through HAProxy using Firefox, I get long delays. If I use Safari or Chrome, the pages come right up without any delay.

If I connect to the Plesk server directly without HAProxy in the middle, there are no delays.

I do not know what would cause these delays that don't occur with other browsers.

I'm on a Mac: 115.0.2 (64-bit)

Prior to getting some desktop PC upgrades that required a new install of Windows 11 and a new install of Firefox, I backed up my entire PC (yea!).

Now that I have re-installed Firefox, I see that I have none of my saved bookmarks and so I want to restore the Firefox profile - all of it or at least the bookmarks.

I have tried following the Firefox instructions for this, but am apparently not doing it right.

I can't seem to locate the bookmarks file, for starters, in my backed up files. I find the profile but I don't find anything like places.sqlite.

Can someone help me so that I am locating the right (and complete) files, copying them correctly, and then switching to the new/old profile correctly?

Thanks in advance.

Dear Mozilla

I wrote to you earlier today about a problem i am having with themes.I change themes quite frequently and have a lot of them on my list. After opening and closing the browser once or twice the list of themes no longer shows what each theme looks like. I reset Firefox and the image of each theme reappears. It's quite tedious as i said to have to do this once or twice a day. Is this problem occurring because i have too many themes on the list?. I have turned off all other extensions and the same problem keeps happening. I don't know what to do.

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).

Today, I cannot open Cox E-mail using Firefox, but I can with Google Chrome (which I pretty much never use). See the error message below, can someone help? I have a Dell E6520 laptop running Window 7. Thanks.

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.
