A white horizontal line in the top of the screen, whilst watching movies in tv5mondeplus.com. This issue happens when installed the recent update 129.0.

Tested in other browsers and doesn't appear the white horizontal line on top.

About two or three times a month the PC randomly freezes completely if a video is running in the actual Firefox browser (regardless of the site, regardless of whether it is in the active tab or in the background). First the image freezes, after about 10 seconds the sound freezes. Only a hard reset helps. The problem is observed both in actual Windows 11 and in Manjaro Linux. In games, rendering, stress tests and other PC works stably, does not freeze. How to solve this problem?

1. Close Firefox (FF) with some tabs open 2. While FF is closed the websites are updated 3. Open Firefox, tabs reopen 4. Go to tabs

Expected: Tabs should the latest version of the website (ie the page has been refreshed)

Actual: Tabs are showing the old, previous (cached) versions of the website and not refreshing to show the latest

User has to manuall refresh each tab to see the latest version of the page

Are other people seeing this issue?

All of a sudden, when I hover over a tab, a small window of the web site that tab is in, appears. Never happened before.

I did go into Performance Options - Visual Effects and unchecked "enable peek," but it didn't work.

How do I stop these windows from appearing?

Windows 10.

As noted by others about recently-prior versions of Firefox, version 129 ALSO fails to play videos (on Amazon Prime) at HD even though other browsers, Chrome and Edge as examples, work perfectly well. This problem MAY have started with a fairly recent version of Firefox (like 127 or 128). See the post right here by another user, earlier Firefox version, with the EXACT same problem:

Since 129.01 i cannot play HD Videos on amazon any longer. This Problem happened alot over the years. It really goes on my nerve. The only reason i cannot get rid of spyware like chrome is because its the only method to watch amazon videos reliably. SD only works, Widevine also had an update yesterday, so maybe its part of the problem. Anyway, did a Firefox reset, testet on another windows machine. Does not work anymore. Please fix it.

I already turned pff the graphic tab preview, but the tab title still pops up when I move my mpuse pointer on a tab. I do not need this and find it terribly annoying. How do I completely deactive this?

Hi,

This has been brought up before, but not with this exact question (not that I could find, at least).

I understand that cookies cannot be synced across devices, but this is not what I am asking for. Is there a way to make firefox sync the list of exceptions? Meaning, only the specified website URL and its status, not the cookies from these sites.

Hi firefox community,

I am using Firefox version 127.0.2 as my main browser on MacOS Sonoma 14.5. For the past few months, when using Firefox in Mac's full-screen mode, I've been experiencing an issue where one of the multiple open tabs unexpectedly displays in a separate window the moment I click on it.

This behavior didn't occur previously, and I believe it started happening about 3 months ago. It doesn't happen every time, but occurs a few times a day when I least expect it, making it difficult to identify the specific conditions that trigger it. I use a Magic Trackpad, and after switching to full-screen using the three-finger gesture, the moment I try to activate a specific tab, that tab alone displays as a separate window in full-screen mode.

Is it possible that a Firefox version update has changed this behavior? If this is a Firefox issue, is there a way to capture debug logs to have the developers investigate it?

Alternatively, if there's an option to prevent tabs from opening in new separate windows, that would be an effective workaround. Could you please let me know if such an option exists?

Best regards,

Until today it worked fine. But now whenever I try to login to Xfinity I get You don't have permission to access "http://login.xfinity.com/login" on this server. It works fine on Chrome and Edge. I have disabled my add-ons. I have cleared cache, cookies, etc. I have rebooted. I have turned off firewall. I have checked my DNS. I have changed the DNS protection to OFF in Firefox. I have checked my proxy setting (I have no proxy). I have reinstalled Firefox. Etc. Etc. Nothing works. The fact that it works on Chrome and Edge, that it has worked everyday until today gets me confused. I also tried using my mobile phone as a hot spot to make sure it wasn't related to my Internet connection or IP address. Anyone have any ideas?

I've added https://x.com as an exception site but it is still blocked.

https://x.com/mozilla doesn't work either

Error message on the page:

"Something went wrong, but don’t fret — let’s give it another shot.

⚠️ Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com"

After 2 days it used to finally load without my doing anything, but not now. I never loads using Firefox.

https://x.com is added as an exception, but obviously ignored.

Tried You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

   hold down the Shift key and left-click the Reload button   

NOPE

Tried: Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings), click the padlock icon (Clear cookies and site data) for the domain in the selected tab.

"Remove the Cookies" for websites that cause problems:

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

NOPE - lost all my bookmarks, extensions, settings - not going there again thank you

as for:

You can check for issues with Enhanced Tracking Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

   click the shield icon for more detail and possibly disable the protection 

the sheild has a slash thru it saying "enhanced tracking is off for this site" when i put my mouse over it.

I just started getting this error:

Secure Connection Failed An error occurred during a connection to www.newsmax.com.

I cannot find how to make this stop. I will get emails from Newsmax about articles and if there is something I want to read I click on the link in the email. I never had a problem with Firefox not opening the link. This just started and I can not get the link to open. I have Newsmax set up as a home setting. However, after I got the Secure Connection Failed error, I could not open the Newsmax web page even if I typed in www.newsmax.com. I am about to uninstall Firefox and use another browser. Can you please tell me how to fix this?

Greetings, Mozilla Community I'm contacting you to ask for help with a problem I'm having with Mozilla Firefox that comes up when I try to visit https://deraltersrechner.de/. It won't load, and I'm not sure if that's because of a bug in the website, a browser issue, or something else entirely.

Does anyone else have knowledge of this problem or recommendations for a fix? I've attempted removing addons and cleaning the cache in my browser, but the issue still exists.

I would be grateful for any advice or ideas on improving the usability of the website. Thank you in advance for your assistance.

Hello, Since the version 128 (x86_64) on Windows 11, SSH links are no more opened with the user. The link tooltip at the bottom of the screen is showing the link without the user too. Ex: ssh://root@10.0.1.1 -> will open ssh://10.0.1.1 instead. Thank you in advance

I'm having problems with a website constantly asking me to accept cookie permissions. It happens on some other sites occasionally, but this particular site is one that I use each day.

When I visit the site I get the cookie permissions box. I click accept all cookies. No matter how many links I click I am presented with the box yet again. It doesn't happen with Chrome, Edge or Brave.

Regular download works fine, but when I try to download attachment in outlook.live.com website, it didn't ask me where to store it, but simply places it in my default location, while at the same time opening the attachment even though I only want to download the file.

When I'm in full screen mode, The Apple, "Firefox" "File" "Edit" "View" "History" "Bookmarks" "Tools" etc menu bar shows up at the top and won't disappear. On my iMac Pro, it doesn't show up. i.e. Off.

I can't figure out what is the setting to make sure it does not appear. I went digging everywhere and can't figure it out. If you could tell me what config, etc I'm missing I'd appreciate it.

Screen shot attached to show which menu bar I mean.

My firefox is up to date: 126.0 (64-bit)

I am using FF 129.0 64 bit on Linux Mint. AFAIK all is up to the latest version.

When I log into my website admin on wordpress, my site gets redirected for a security check on the server (lightspeed or PC Guard). Once this is complete, the login continues.

Unfortunately for the last 6 weeks, my website redirects with a message, "Verifying that you are not a robot" and it hangs there permanently.

I have tried to get my server to disconnest Lightspeed and PC Guard (but then have NO security protection). Nothing seemed to work, and access was sproradic, but seemed best when FF was completely cleaned, cache, cookies, etc. However, even this did not guarantee a login.

Then I found that all worked perfectly using Chrome. Further, having logged in using Chrome, the FF version would now be unlocked and work perfectly.

So it seems as though FF is not clearing a status/flag/file somewhere and that Chrome clears this, leaving FF working again - for another 24 hours. Then the whole cycle starts again.

Any ideas?

Mark
