Hello, sadly I have the problem since a few days that firefox opens a new tab with the same error every time I google something or click on a new page/subpage etc. The URL on the error page is all the time "https://0.0.0.1/" mentention of course a page loading error. I don't know why firefox keeps oppening new tabs with this URL. I allrady tried to use the clearing function and even reinstalled the software, nothing worked. Maybe somebody can help me solving this problem, it is very annoying to have multiple new error-tabs per minute in a normal work flow. Thanks and best regards, Thomas

Dear Sir or Madam,

I have been having problems with Firefox on my Desktop-PC for about a week now: I am almost always shown another tab with an error message (an new tab with allways the same content) in addition to the website that is regularly called up and also works:

Tab-Headline: Seiten-Ladefehler Fehler: Verbindung fehlgeschlagen

Beim Verbinden mit 0.0.0.1 trat ein Fehler auf.

   Die Website könnte vorübergehend nicht erreichbar sein, versuchen Sie es bitte später nochmals.
   Wenn Sie auch keine andere Website aufrufen können, überprüfen Sie bitte die Netzwerk-/Internetverbindung.
   Wenn Ihr Computer oder Netzwerk von einer Firewall oder einem Proxy geschützt wird, stellen Sie bitte sicher, dass Firefox auf das Internet zugreifen darf.

It doesn't matter which regular website I call up - it also happens when I call up the Mozilla Firefox page.

It is as if my website call is executed twice: once normally and everything is displayed correctly. And once as an extra tab with an alleged page loading error where the connection has failed.

How can I prevent these additional tabs with the error message from constantly popping up and being displayed? I have not made any other settings and Firefox has always worked perfectly so far. It doesn't happen with Google Chrome, for example - so it's not my PC.

Can you help me?

Kind regards Daniela Bohle

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

I loaded the postcode lottery website but it's completely blurred. I last checked the same website last month, and it worked fine. I have cleared the cookies from Firefox, but the result is the same. It appears clear for a moment, then blurs. No pop-ups asking to accept cookies. It works fine using Chrome. Any idea why Firefox won't display it properly? It loads the National Lottery website, so it's not about gambling sites I guess.

I recently lost my firefox configuration and now see the Amazon.DE search engine rather than Amazon.com. I have no idea why...

I followed assorted support guides but haven't been able to add the Amazon.com search engine: https://support.mozilla.org/en-US/kb/add-or-remove-search-engine-firefox#w_add-search-engines

1) I clicked the link "find more search engines": https://addons.mozilla.org/en-US/firefox/search-engines/. This took me to a generic list of extensions and didn't find an official amazon search option for the search bar. Those suggested had few downloads and weren't vetted by mozilla

2) I visited Amazon.com and then clicked the magnifying glass with the green plus sign in the search bar. Then tried to add amazon.com as a search engine but got this error:

Firefox could not download the search plugin from: https://d2lo25i6d3q8zm.cloudfront.net/browser-plugins/AmazonSearchSuggestionsOSD.Firefox.xml

Can someone explain how to get this working again; I just want the normal amazon.com search in the search bar

I recently updated to 125.0.1 and now get 'failed to check for updates': - when I manually check (help > about Firefox) (see image) - in 'settings' it also shows 'failed to check for updates' (see image) I never had such a problem with previous versions; any suggestions?

Firefox periodically says I am "forbidden" to enter my Kaiser website (KP.org). I know what Mozilla recommends as a fix, which is to clear data and cookies. But this creates more problems because I have to re-enter passwords and other settings. This is a problem Mozilla's website reports has been occurring for YEARS! Why can't Mozilla/Firefox fix this? Please tell me there is a better way to fix this problem.

Since a day or two the font size on my Menu Bar is way too small. I have been searching around and the solutions are not working or not what I want. I do not want to zoom in, I want my page size to remain the same, I only need the font size on the menu bar back to what it was. I tried the userChrome.css method and it did not work

Microsoft Outlook sign in screen does not load on Firefox. Please see the attached image. Every time I need to read my mail I have to open Chrome , which definitely I want to get rid for good. Any solution ?

Okay, I am unable to get into my bank online even after doing steps to fix Error code: PR_CONNECT_RESET_ERROR checking the site, it says this is at firefoxes end

When I load www.foxnews.com a popup box comes up and says to view the news to turn off my ad blocker, and then makes the site inoperable. I can't find an ad blocker so I'm thinking I might have a security setting wrong. I can view the website in Chrome with no problem. Any help is appreciated. Gary

Within the Add-on Manager by clicking Manage Extension Shortcuts - you can make shortcuts for add-ons to perform specific functions via the buttons on your keyboard, but I want to actually be able to use the buttons on my actual mouse rather than the keyboard.

Does anybody know if this is possible? Currently when I try to use my mouse to input a 'shortcut' in the 'Type a shortcut' box nothing works.

Are there any about:config settings or add-ons that can enable me to use my Mouse to make shortcuts for my add-ons?

Hello everyone. Well, I've been using Firefox for a few months, maybe a semester now, I don't remember. But the point is that since yesterday I have been facing a serious problem of not being able to download any type of file (MP4, PDF, .JSON, ISO, etc.). I've already used the troubleshooting mode and I've also restarted my laptop, but it didn't help. I've also gone to the advanced settings (see 'about:config > browser.download') and reset/deleted the data for each command but the problem still persists.

What happens is the following: I click to download the file in question, however, nothing happens other than the page loading that commonly occurs when downloading something. Still, the file does not appear in the downloads tab and there is not even the option to choose where to save the file (e.g. Downloads folder, Documents folder). The download simply appears to have failed.

Exactly, it 'appears', because today I discovered that all my downloads were being directed without my permission/action to the 'downloads' folder (And that's not where I want them to go). The problem would be smaller if only this happened, as I would then just get the files downloaded there and then change to the desired folder, thus trying to move forward despite the problem. But the downloaded files themselves are not operational, they have the icon when a file is still downloading, in addition to not having a name, everything being just a cluster of codes.

In the end, there are files, large and small, that have no use and that I don't even have control over where to direct them. Which is still a huge problem because I still technically can't download anything from the browser. Please, I really need your help on how to resolve this problem.

Note: Also, when I close and open the browser, the first download I try appears in the downloads tab, but it fails instantly and cannot be resumed, making it an eternal failure.

Hello, dear Firefox Help people!

I keep a lot of tabs open in my Firefox browser (121.0 64-bit for Windows 10). Starting just recently, if I closed Firefox by clicking on the "X" in the upper-right corner of the window, then the next time I start Firefox it opens without my tabs! (It never used to do this before...) It's very disconcerting, but I found that if it starts up without my tabs, Ctl+Shift+N will open Firefox in another window--with all my tabs! I can then close the original window (the one without my tabs), and go on using Firefox in my normal way.

If I have Firefox running with my tabs present, and I close Firefox by using Ctl+Shift+Q, the next time I re-open it, all the tabs are there. (That's also the case when I close Firefox using the three-line menu and "Exit".) But I used to be able to close Firefox by simply clicking on that "X" in the upper-right corner of the window, and next time I started Firefox it would open with all my tabs intact. I'd like it to work that way again... What must I do to get it to return to working that way?

(Please note that under Settings/General/Startup, I do have "Open previous windows and tabs" checked...)

Thank you for any help you can provide...!

What happened to "recent bookmarks"??? I is no longer available....why???? I need it back, as I used it all the time and my bookmarks were very easy to locate. Now I have no idea where a bookmark is, that was even bookmarked an hour ago.

I've noticed lately that my Firefox keeps freezing and hanging up at random periods for no apparent reason. I have very few plugins and it even happens with them all disabled and removed. I've tried resetting Firefox to default everything yet it makes no difference.

Also I can not clear history. I've tried multiple different clear history plugins but none of them work at all. And when I try the traditional way of clearing Firefox history the window pops up and then the entire browser just freezes while 'clearing' and never gives me back control, I have to force quit and restart to regain control. And then when I relaunch the history is still not cleared!

So aside from the constant lagging and lockups it seems that any attempt to delete history whether using the inbuilt function or adding plugins messes up the whole browser.

Googling this issue it seems others are having the exact same problem with Firefox and yet any suggested solutions (reset browser) don't seem to be working for may of them.. Or me.
