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?

If an URL already have many tags or longish tags I can no longer see suggested tags when starting to type tags. Image example illustrates. This URL already have the following tag list:

1942, Air_Ministry, boost, cruise, memorandum, MP, rpm, Spitfire, Spitfire_MkIX, Spitfire_MkV, Spitfire_MkVI

Old behavior was if started to type ", spi" it would list suggestions:

Spitfire Spitfire_MkIX Spitfire_MkV Spitfire_MkVI

Easy & clear to select from.

Now it lists all already existing tags before each suggestion:

1942, Air_Ministry, boost, cruise, memorandum, MP, rpm, Spitfire, Spitfire_MkIX, Spitfire_MkV, Spitfire_MkVI,Spitfire 1942, Air_Ministry, boost, cruise, memorandum, MP, rpm, Spitfire, Spitfire_MkIX, Spitfire_MkV, Spitfire_MkVI, Spitfire_MkIX 1942, Air_Ministry, boost, cruise, memorandum, MP, rpm, Spitfire, Spitfire_MkIX, Spitfire_MkV, Spitfire_MkVI,Spitfire_MkV 1942, Air_Ministry, boost, cruise, memorandum, MP, rpm, Spitfire, Spitfire_MkIX, Spitfire_MkV, Spitfire_MkVI, Spitfire_MkVI

Suggestions are scrolled right invisible outside the input box.

Who thought this was a good new feature? It adds nothing, I can already see existing tags, why would I want to see them repeated for each new suggested tag (while not actually seeing the suggested new tag)?

How can I turn this *!$&@! off and return to old behavior?

Videos won't load in previously enjoyed timeframe or indeed et all sometimes. timeouts when loading pages. speeds are like 15 years ago even in troubleshoot mode and after refresh. when can I expect improvement?

Hi, after upgrade of ubuntu to 24.04 i got into problems with using Firefox. I it running on x11 with proprietary nvidia driver, no matter of source package (snap or deb from the Firefox repository) and no matter of safe mode the Firefox gets frozen when clicking into any dropdown control in side page, the same happens when trying to open bookmark folder in the bookmarks panel or even the dialog that opens from the star icon in address folder that should add page into the bookmarks. When running on command line, in case of the snap version there are just some warnings of some missing css file, in case of the deb version it does not output anything suspicious. I was even trying to change the UI theme (qt) as well as GTK theme in case it makes any difference, but it did not... Thanks for any help.

I am having trouble pinning any Extensions to my toolbar. When i click on the Extensions icon (puzzle piece), the Extensions menu immediately pops up. My extension (Bitwarden) is set to "Enabled". When I click on the three horizontal dots, however, the only options are 1) Remove, 2) Report, or 3) Manage. There's no option given to pin the extension.

Because of that, the extension basically never opens, and I am unable to use it. Does anyone have any suggestions for me? Thanks in advance.

I am running Firefox 129.0.2 (64-bit) in Windows 11 on a Surface tablet. FWIW, the extension is running fine in Chrome.

Hello. How do I do if I want Firefox to open a new window every time I click on the icon? I tried to insert the command "-new-window URL", which used to work before but it doesn´t anymore. Is there anybody out there who knows something about this?

For years, I've been looking for a way to disable the space bar from acting as a page down button, including trying out scripts to solve it, but please let users disable that shortcut in the about:config page.

It is difficult for me, since I see that ability to change what the backspace does is available, but there's no option for the space bar. The space bar is something that I often accidentally hit, and it would be of immense relief to me to no longer have that issue of it paging down what I reading. This is my request, and there are others who also feel similarly.

Why do PDFs come out so small when printing? ie. taking up only about 40% of an A4 sheet? Selecting "fit to page" or "scale" etc in the print dialogue makes no difference. Images: 1. Desired size. 2. Actual printed size. 3. Print dialogue.

So, it happened again today. Saw their commercial on TV today and went to legacybox.com (NEVER BEEN THERE BEFORE; they transfer VHS tapes, and other stuff, to digital) and got an email from them after closing the browser tab and leaving their website. While I didn't open the email, their email Subject/title was "Thanks for stopping by...".

All I did was look around their website for a few minutes AND DID NOT GIVE THEM MY EMAIL ADDRESS!

This is EXTREMELY DISTURBING!

PLEASE, If anyone here has the Video DownloadHelper extension installed in Firefox AND their Companion App (it costs ~$28, I think.. so don't bother if you don't have it). And make sure you've updated to a recent version, WHERE THEY HAVE YOUR EMAIL/Licens# IN THE SETTINGS (L click on the VDH icon, click on the gear icon, and at the bottom of the menu, click on "More settings....". If your email is there, PLEASE GO TO Legacybox.com AND SEE IF THIS SITE SENDS YOU AN EMAIL as this may help to confirm if Firefox is leaking emails thru that app. Thanks!

Firefox no longer starts up. It crashes and stops responding on MAC Monterey 12.7.4 This is as far forward as it will go on this old mac. Everything worked fine yesterday, start up today and no go. I removed the profile and attempted to restart. No joy. So I downloaded a fresh copy and installed it over the old version. No joy. Cannot access profile manager. Removed version and fresh install, still no joy. How to I get it to launch, then How do I recover data from old profile?

Hi,

I cannot use 'Windows Snipping Tool' to screen-capture some information on 'Protected Content' on Mozilla Firefox. Is there a reason for this? Thank you.

I'm using the latest Firefox on Win10, with a fairly powerful laptop (64 gb RAM, intel i7 2.3 GHz chip), and for about a month now, whenever I use it, it uses so much CPU all the time that my laptop is overheating (slight hyperbole, but it's definitely churning the fans a lot, and the area around the keyboard gets hot to the touch). Sometimes it uses up to 45% CPU, and over 20% memory!!! (as reported in the task manager) Usually around 20-25% though. While Chrome, at the same time, is using 0.1%. It's not just when starting up, either, it's continuous during use, until I quit Firefox.

What the h*** is going on?!? I've tried the troubleshooting steps, but it remains crazy regardless of turning off extensions, and I'm just using the default theme. I notice it's mainly when loading images, like on social media.

This is insane. What is happening. Can someone help me?

Unfortunately using a date type toJSON() result is not accurate. It first apply client timezone and then convert it to json string. In my scenario I am simply read from an API which return a none standard datetime string without its timezone (like "2020-11-21 00:00:00"), Then I try to convert it to a date using new Date("2020-11-21 00:00:00"). Then I use it in another web service but it apply my client timezone when I use JSON.stringify() method (or toJSON()). Does this behaviour is intentionally?

I read the other same question but I am not okay with it. https://support.mozilla.org/en-US/questions/1414380

Windows 11, Firefox 129.02

I've done both a refresh and a clean install and the problem persists. Fonts set to "allow site to substitute"

In Google Maps (maps.google.com), the street names and route numbers (graphic) disappear after a second. This happens in both regular and incognito windows, and regardless of zoom level.

Oddly, when I set privacy.resistFingerprinting in about:config to True, the street names appear, but route numbers are just color boxes. When set to False, I can see both for a second before they disappear.

For a few days now whenever a new tab opens, either by clicking a link in search results or by clicking a link in an email, the cursor jumps to the bottom of the page and I have to scroll to the top of the page. I'm just getting started with Windows 11 on a new computer. What happened to cause this?
