I've been not able to access any website 'cause of this PR_END_OF_FILE_ERROR I clearly checked it and connected all the networks but it's not accessing any website, i need help ASAP

I am looking for a way to make the Firefox tab close button "x" bolder without affecting the background style. I tried using filter but I do not want any shadows or anything like that just to make the item itself not bigger but bolder - any ideas? Thank you all look4

I live with Firefix always in full screen. I Don't like seeing any bars or buttons of any kind.

Befor the latest update, when I moved my mouse to the top of the screen my tabs popped down and in the top right corner was the standard icons for "minimize" "maximize" and "exit".

With the latest update the tabs are there but the 3 buttons have gone.

If I exit full screen (F11) then they are there again, but I dont want to have to exit full screen every time I change between programes which I do every few mins. I'd be popping pages in and out of full screen every few mins!

How do I get the buttons back all the time?

Hello to all members of Firefox team. In the place we live, the ISPs all turned on safe search mode for users without their satisfaction. All we can do is turn that off. But in the Firefox we can't do that. Please let us know how to turn it off with a Firefix to Firefox.

As the subject describes, installing Bing Wallpaper causes the vanishment of icons of the six default search engines in my region (China Mainland), i.e. Baidu, Wikipedia (actually the icon of Wikipedia is still there), Bing, Google, Amazon and DuckDuckGo, but these search engines themselves are still usable though. It is probably caused because I chose the choice that setting Bing as my default search engine of all browsers and the application (Bing Wallpaper) reset all those engines. I have tried removing these engines from my settings list then adding them back, but the icons are still invisible. I have not tried to uninstall and reinstall my Firefox.

My Firefox version: 94.0.2 My OS version: Windows 7 6.1.7601, Service Pack 1

Firefox for desktop is not syncing passwords from Firefox on Android.

I had to reinstall Windows on my PC and downloaded Firefox, but the passwords are not syncing from my Android to my PC. All my bookmarks, address, etc synced, but not my passwords. HELP!!! I do not use a master password.

Until recently, I resisted allowing updates for Firefox because of the announcements of changes to prevent access to some technical kinds of website which I use. These include the public websites of the Paris Observatory which include useul informational ftp pages with important text, data and software files.

  I did recently allow a Firefox update, and now I find that I am cut off from access to these ftp pages. 
  How can I re-enable access to ftp? If it can't be done in the new version of Firefox, how can I return to an older Firefox version that does allow such access?

How do I permanently delete specific bookmark restore dates from Firefox 92.0, 64 bit? I am running Windows 7 pro. Older versions of Firefox gave me a delete option. Not anymore. I cannot eliminate specific restore bookmarks dates from the restore option. How do I do it? If necessary, I will uninstall Firefox completely. Thank You.

Hi I am trying to visit a website but It is showing an error I am not sure why The website says that

Your browser did something unexpected. Please try again. If the error continues, try disabling all browser extensions.

Is there any browser issue because I am not using any extensions or ad blockers?

Hello there , I am trying to modify the menu-bar dropdown items when I hover over the list that opens with my mouse ( the dropdown list of any of Help , Tools , Bookmarks , History etc...). It is barely noticeable. I can hardly see the item chosen. I could use some help using the css. I am using FF93 and my platform is win7. Thanks look4

Sleep disorderland denizen here. i use dark mode a lot and love it. The problem is the sudden flash of white background when i open a new tab before the page loads. Is there anyway to override/change that also to black permanently. Thank you.

After a refresh of Firefox I lost all of my bookmarks. I have tried everything that online support suggests but nothing I do works. Please help! I have years of bookmarks that are very important to me.

Thank you

after the last update, the keyboard shortcut shift+esc opens the processes menu. i would like to disable it - this is the same shortcut that i frequently need to use on a specific website, and needing to close the processes menu every time is deeply annoying

I do NOT appreciate that Mozilla now forces me to use the FireFox home page (or else literally nothing - a blank page) for my new tabs. I want to use the same custom page I have set up as my home page, but since the last update, that page only shows in a new window, not on new tabs. Is there a workaround for this? I use multiple tabs within the same window heavily, and having FireFox abruptly override a customization I have already set up and been using for years, that works best for me, is seriously pissing me off. I know there is a plugin to se new tabs, but I already have several plugins and would prefer not to add more.
