Diễn đàn hỗ trợ Firefox

I have my settings set to automatically update Firefox. Earlier this week, Firefox 131.0 was installed through this automatic update. Since then, Firefox repeatedly and randomly crashes, and I have no idea why because it did not happen with previous Firefox versions. There seems to be a bug in the new release that is causing this.

I am unable to use my bill pay with my bank using Firefox browser. However, I am able to use it logging on with Microsoft Edge. What has changed with Firefox recently? This has only become a problem as of today.

Hi,

Firefox Developer Edition 126.0b7 (64-bit) shows a perpetual "Loading" screen when trying to access my internal Logitec Media Server at 127.0.0.1:9001.

Other browsers like Waterfox Classic have no trouble, so LMS is working fine.

I tried cleaning the cookies, disabling the firewall (Windows 10), that did not help/

Any idea how to solve this?

Thanks.

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

Since Mozilla Firefox web browser v127.0 (released June 11 2024) the manual installation of the Adobe Acrobat Pro extension (the adobe_acrobat-1.0-windows.xpi file) do not work anymore!  :disappointed_face:

So, when you go in any higher version of Mozilla Firefox web browser then v126.0.1 (released May 28, 2024) to this web browser Menu Bar -> Tools -> Add-ons and Themes -> Extensions -> Install Add-on From File..., and then try to manually import-install the Adobe Acrobat Pro extension (the adobe_acrobat-1.0-windows.xpi file) into the Mozilla Firefox web browser, and from this HDD location:

C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\Browser\WCFirefoxExtn\WebExtn\signed_extn\adobe_acrobat-1.0-windows.xpi

The Mozilla Firefox web browser will say during this .xpi file installation: "This add on could not be installed because it appears to be corrupt"!  :disappointed_face:

However, in any Mozilla Firefox web browser version prior v127.0 (released June 11 2024), this manual import-installation of the adobe_acrobat-1.0-windows.xpi file will be most successfully installed in a Mozilla Firefox web browser without any problem!

I also create the most detailed and step-by-step post on the Mozillazine.org Forum and the Adobe Forum about all of this problem:

So, please help and advice further. Thank you in advance and best regards!

I have my settings set to block audio and video from auto playing (I have limited data) and amazon.com still auto plays advertising and 'influencer' videos, why?

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:

https://support.mozilla.org/en-US/que.../1455729

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.

There's one specific field I fill in very often and for some reason Firefox is really keen on suggesting me two searches that I looked up more than a couple months ago, on a totally different site. I can't even remove these suggestions or add new ones. When I used Vivaldi, it'd learn what I insert (even if it'd end up suggesting tens and tens of options), while Firefox doesn't learn at all.

For sake of an example, let's say that the word I use every day in this field is XYZ. Not even once was it suggested to me, I've only ever gotten the two in the screenshot below instead. And I can't remove them using the Delete key as some other article suggested.

Speaking of which, I just noticed the same thing happen to the subject line in this form 🙃

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.

I have been using Firefox since shortly after it was released. As I am fond of wine I often visit the web site systembolaget.se. But since 2 months ago that site is not readable with Firefox It shows very small pictures and text that is so smal I cannot read it. My solution is to use Chrome which shows everything as I am used to. I have not observed this type of problem with Firefox at any other web sites. Best regards, Håkan

Firefox is displaying menus IN CONTENT (not the Firefox hamburger) as hamburgers when they are supposed to be full text menus. Microsoft Edge and Google Chrome display these menus IN THE CONTENT correctly. Firefox is turning them into burgers.

This is happening with a website I own. It started when I changed ONE side menu on ONE web page to a hamberger. Firefox then began displaying ALL menus on ALL pages as drop-down burgers. The other two browsers did not engage in this stupidity.

These three images are the same page at the same time.

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?

Dear Firefox Support,

I am experiencing an issue with YouTube and some other websites not loading properly in Firefox. The sites continuously try to load but never fully display. I've attached a video link demonstrating the problem for reference: Video Link Video Link.

Could you please look into this issue? I’ve tried clearing the cache and disabling extensions, but the problem persists.

Thank you for your support.

Best regards,

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.

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.
