Firefox supportforum

When a playlist is loaded and played on YouTube, the next video in the playlist should automatically start playing once the current video reaches its end. This feature is commonly known as autoplay. However, I couldn't get it to work consistently. When the current video is finished, next video is loaded normally but where it should automatically play it doesn't.

I have tried below to address this issue:

• Autoplay next video works in safe mode.
• "allow audio and video" in autoplay permissions in https://support.mozilla.org/en-US/kb/block-autoplay doesn't help
• I have also set media.block-autoplay-until-in-foreground preference to false in about:config but didn't help
• I have tried uninstalling all extensions and it didn't help
• Tried logging out of youtube, but this didn't seem to help with the issue.
• Tried "Clear startup cache" in "more troubleshooting information" menu, didn't help
• Tried "Refresh Firefox" which didn't help

Thank you.

I can no longer view YouTube videos in Firefox browser because they think I have some kind of add blocker installed. I have never installed such a thing and have no idea how to fix what they are demanding I must fix in order to continue with YouTube in the FireFox browser. In the mean time I have to use some other unfamiliar browser just for YouTube. It appears that some kind of incompatibility has evolved in the recent two or three weeks between Firefox and YouTube.

Hi, Hope you all are doing well. I recently checked my website [removed] on different browsers. Website is working fine with most of the browser, but when i checked it on Firefox i got an error in DevTools "Image corrupt or truncated". What does it mean? This is a category image and present on sidebar of website. But all other images are same, i mean with same size and format. Why exactly this image is creating an issue?

Kind Regards, Hassan Mujtaba

This issue started a couple of weeks ago. Whenever I move my mouse, very glitchy blocks sometimes appear on the site I'm using. Their behavior is very different, some blocks stay in a static position for a while, and no amount of moving the cursor changes that. Other blocks disappear as soon as I move the cursor or scroll up or down. The color of the blocks often matches the website background, but sometimes they are just white (this often happens when I highlight text, making it impossible to see) or black. (I really wish I could send a video to really show the behavior).

On some websites, there are no issues (like mozilla.org) while on others the website basically becomes unusable (gmail.com, my uni's website as seen in the pictures).

I really hope someone can help me, I reeeally don't want to switch to Chrome.

My system: ACER Spin 5 SP513-55N77LC Windows 11 Intel Core i7, 16 GB RAM Firefox version: 118.0.2 (64-bit)

What I've tried: deleting all add-ons restart computer several times un- and reinstalling firefox scan for viruses using another browser (no issues there)

I updated from version 106 to the latest version just now and my user-defined fonts stopped displaying on a local HTML page (stored locally on my computer); this warning showing up in the console: "Request for font FONT_NAME_HERE blocked at visibility level 2 (requires 3)."

I specify fonts using "font-family" property (CSS).

Help me out here, please. How can I fix this (so my pages look proper again)?

Thank you.

I use Kubuntu 23.04 with Firefox from mozillateam/ppa apt repository, got update to FF 119 today (package 119.0+build1-0ubuntu0.23.04.1~mt1) and after the update Firefox stopped using system-wide installed fonts (either from /usr/share/fonts or from ~/.local/share/fonts).

So for example fc-list finds Gentium Plus (/usr/share/fonts), Iosevka and Junicode (~/.local/share/fonts) on my system: % fc-list -f '%{family}: %{file}\n' | rg -i 'gentium plus:' Gentium Plus: /usr/share/fonts/truetype/gentiumplus/GentiumPlus-Italic.ttf Gentium Plus: /usr/share/fonts/truetype/gentiumplus/GentiumPlus-BoldItalic.ttf Gentium Plus: /usr/share/fonts/truetype/gentiumplus/GentiumPlus-Bold.ttf Gentium Plus: /usr/share/fonts/truetype/gentiumplus/GentiumPlus-Regular.ttf % fc-list -f '%{family}: %{file}\n' | rg -i 'iosevka:' Iosevka: /home/silmeth/.local/share/fonts/iosevka/iosevka.ttc Iosevka: /home/silmeth/.local/share/fonts/iosevka/iosevka.ttc Iosevka: /home/silmeth/.local/share/fonts/iosevka/iosevka.ttc Iosevka: /home/silmeth/.local/share/fonts/iosevka/iosevka.ttc % fc-list -f '%{family}: %{file}\n' | rg -i 'junicode:' Junicode: /home/silmeth/.local/share/fonts/junicode/otf/Junicode-Bold.otf Junicode: /home/silmeth/.local/share/fonts/junicode/otf/Junicode-Regular.otf Junicode: /home/silmeth/.local/share/fonts/junicode/otf/Junicode-Italic.otf Junicode: /home/silmeth/.local/share/fonts/junicode/otf/Junicode-BoldItalic.otf

but when I try to apply the style `font-family: Gentium Plus`, `font-family: Iosevka`, or `font-family: Junicode` to an element, Firefox doesn’t use those fonts and instead in the element inspector I see Noto Serif is being used instead.

Before the update the appropriate system fonts were being chosen for rendering by Firefox.

When I upload my personal web page some images are missing, link banners won't display. I need to know if mozilla/firefox is censoring my sites and if so WHY? They display fine in other browsers. I used the developer console to identify the issue, seems that firefox is altering the html data to not display the link banner. See attached image.

Hi,

I am using Linux Mint 20.3, 64-bit and both Firefox and Chrome are not loading images for me on certain websites (i.e. okcupid). In particular, I am noticing that images will actually load for a split second and then disappear moments later.

I've tried disabling my adblockers, deleting my cookies and cache, running Firefox in Troubleshoot and Diagnose mode, running Chrome in Incognito mode, and evening uninstalling and reinstalling Firefox. Still the issue persists.

I followed the advice here: https://support.mozilla.org/en-US/kb/fi ... s-not-show

Any advice or suggestions would be most welcome.

Thanks, Chris

Google Calendar has not worked right on Firefox (version 118.0.1 (64-bit)) on macOS since I updated to macOS 14.0. For example, when I try to use the "Search" function, I can't type a search string. Or sometimes when I create an event I have problems typing in the event title field as well. On these occasions when it doesn't work there is no blinking cursor placed at the left end of the text field, so you can't type in that field.

Hoping that this isn't just me, since I really like using FIrefox. Have had to move to the Edge Browser because Google Calendar is a central tool for me that has to work without having to fiddle around.

The horizontal scroll arrows are not working on Amazon prime video using Firefox on a pc running Win10.

It hasn't worked for some time and I thought it was an Amazon problem, but I've tried other browsers and devises and it works on all of them EXCEPT Firefox.

My Firefox for pc is up to date. I have uninstalled and reinstalled twice. I have tried cntrl +/- thinking maybe I just wasn't seeing them - they're not there. All drivers are up to date.

I don't want to use another browser but i use Amazon prime video a LOT and this problem makes it nearly useless. HELP please?

as of 2023/09/29 hulu, netflix, prime and disney+ are not playing videos on firefox, after making zero changes to settings or configuration.

I tested Netflix on Google Chrome and videos played, confirming this is a Firefox issue. I cleared recent/all history and changed passwords for those sites. Netflix logs me out if I attempt to play content. Speedtest reports 200 mb/s. Mozilla VPN is installed but turned off. Netflix sign in reports a new device/login in my state which is different from the VPN setting so this confirms that the VPN is not active and blocking content. HBO/Max videos play correctly and that site does not have the same issues. Firefox has crashed numerous times in the last two weeks. Sometimes just a single tab, sometimes a full application insta-quit.

I prefer to compartmentalize usage across different browsers for privacy/security reasons and would like to continue to use Firefox for these streaming services.

Middle click on ordinary text links works as before. But on some pages a middle click on a button shows a vertical scroll up/down icon as when middle clicking outside the button, instead of opening link in new tab.

The problem begun Friday 29 September after I updated from previous esr-version (think it was 102.-something). I have tested on my old Windows 7 PC, and it worked fine before update, but same problem after updating to 115.

I have verified that about:config browser.tabs.opentabfor.middleclick = true.

One example from a free site: https://sok.riksarkivet.se/scb-fodda-vigda-doda?Forsamling=huddinge&Lan=0&DatumFran=1880&DatumTill=1890&Dokument=F%C3%B6delse The green button with text "Bild" is the problem.

Just fund that the green "Bild"-buttons on other pages on same site works just as before: https://sok.riksarkivet.se/?postid=Arkis+eef4e56e-60a2-4221-9c36-8a7a68280d28&tab=post&flik=1&s=Balder

Hello:

I must use the magnifier that came with Windows or I cannot read the screen. All was fine until Firefox updated. Now, when I try to use the magnifier, Firefox and all the sites I am using freeze. The entire screen fades out, and an hour glass shows up. But nothing happens after that. I have to go to the task manager and close Firefox, then start it up again.

I checked for Windows updates and everything is current. I am using Windows 10.

How can I fix this?

Since yesterday (Sep 26 2023), Twitch.tv has been having multiple issues related to basic functionality of the website, and this has happened before but I did not report it because I was able to fix it. I can not purchase or use bits despite Twitch having a stored payment method on file that I have confirmed has sufficient funds, I can not subscribe or gift subscriptions despite Twitch having that same sufficiently funded payment method on file, I can not redeem or earn channel points, I can not send or receive Twitch Whispers (a form of DM), I can not follow or unfollow channels, and I am convinced that if I was to log out, I would not be able to log back in. I can chat in stream chat, and I can watch streams, that's all I can do. But I enjoy using the other features that are currently blocked, I am over 18, and I am the only person that uses this computer, so there should be no parental controls problems either. Yesterday, I restarted my browser, which did NOT alert me that it had updated, and all of this functionality was broken. Roughly 6 months ago I was having the exact same issues, but I was able to fix it by disabling many of the anti-tracking protections on my browser (had to disable them universally except for blocking cryptominers, not just with the shield icon). However, now, even with those settings unchanged, roughly 75% of the features of the website Twitch.tv are nonfunctional. I have included a cropped screenshot of me attempting to redeem something using channel points, the purple box is the button, and the spinner icon stays there for over a minute with nothing happening, which is not how that is supposed to work.

I enjoy watching streams and interacting with people on Twitch.tv, and I wish to continue doing so in the way I am accustomed to. However, it would appear that Firefox has other plans. If this continues, I will be forced to switch to a less secure browser for specifically that site, which is an idea I do not look forward to.

Any ideas why I am seeing these strange rectangles on Google maps?

Confirmed not caused by an extension as I still see them in Private window and do not see them when using Brave.

They don't stay in the same geographical location when zooming in and out.

Firefox 117.0.1 (64 bit) Build 20230912013654 Windows 10 Home - Version 22H2 OS build 19045.3448 The link to download my Sears credit card statement in pdf form has disappeared when accessing the website (https://citiretailservices.citibankonline.com) with Firefox. It still appears and works normally when the website is accessed with Chrome. I have the uBlock Origin extension installed on Firefox, but it is disabled on the Sears website. Screencaps attached.

I've been having an issue for a while now where the cloudflare challenges that ask you to click the check mark to "verify your connection is secure" would just endlessly ask me to click the button and never continue. Sometimes it would say to unblock access to challenges.cloudflare.com.

But if I a launch an incognito window I can visit website with the challenge and it won't even ask! I've added all my extensions to run in incognito mode and everything still works, I can visit the websites in incognito just fine. So the one changing variable is incognito vs non-incognito.

I can have two windows open, one incognito and one not, and browse to the same website and the non-incog window will fail but the incog will just go to the site.

I thought incognito was supposed to only affect the session storage? Does it silently change other things to the running environment of the browser (about:config options, slightly different extension configs)?

Anyone know why this small change would suddenly allow cloudflare challenges to work?

I am using FF on a Windows 11 desktop. When I try to log into familysearch.org using FF, Avast detects that I am being redirected to https://590-buk-726.mktoresp.com. I have used both Avast and FF for years, and this is the first time this has happened. FamilySearch is a very legitimate genealogy site. I contacted Avast and they refreshed FF, and I was able to log in ok, but when I tried it again I got the same warning. I cleared all cookies - same problem. I deleted FF and re-installed - same problem. I am not getting this warning when I use MS Edge. Has anyone seen anything like this? What should I do? Thanks, Mike
