When downloading any file in Firefox (the picture is an example), the "Firefox" option will be added in the right-click open-with in Windows Explorer. This does not happen in other browsers. And this item is added without permission, it is a bad behavior.

在Firefox中下载任意文件（图中为一个例子），在Windows 资源管理器右键打开方式中都会被添加“Firefox”选项，这不会发生在其他浏览器上，而且一个浏览器未经允许添加一个打开方式是不好的行为。

I am using Arlo security cameras which store the video captures as MP4 files. The Arlo app has video playback feature that works in Chrome or Edge but does not work in FireFox. From what I have been abe to glean from searches, Arlo uses HEVC Codec that FireFox either isn't compatible with or is lacking the codec. Any suggestions?

Is it possible to spell check the entire web page using both Hunspell built-in dictionaries and user-defined dictionaries *.dic, already prepared text in Firefox. As it is done in text editors like Libre Office (also uses Hunspell) but for web site, checking the text from top to bottom with errors in a separate window, so spell check is not only in the text input/search field.

The latest update has caused all the open message tabs to disappear. I need to access those messages, as they all require responses. I can't remember what they all are. How do I get them back?

I use this addon

Select After Closing Current

But apparently I'm not using it correctly.

When I close a tab, it defaults to the tab on the right, which, to me, IMO, is counter intuitive.

And just as bad, when I restart the browser, it opens to the tab on the right much of the time, instead of the current active tab.

Is there something I can do can do about this?

Since my last Firefox update, tabs crash or freeze and cannot be resolved. Each time, I have to shut down Firefox to open a tab. This makes shopping impossible as links to payments do not respond or say they are loading but never load. I have tried all the possible solutions and fixes mentioned on here but nothing is working. I have never had any trouble with Firefox before so this is a pain.

About three days ago, the dropdown lists for various websites I use stopped populating unless I use the backspace. So, for instance, if I want to find "John", nothing happens if I just start to type it in. But if I type in "Jo" and then backspace, John pops up. (Perhaps important: Even though I have now deleted the "o", only John pops up, not names beginning with J but followed by a different letter.) Curiously, it seems like the first time each day that I go onto any given website, the dropdown does populate properly, but just that once. I checked Edge and Chrome, and the dropdowns work fine there, so it's definitely a Firefox problem. Any ideas about what is going on and how I can fix it? Thanks.

Is it even possible to create a customisable Add ons just by adding keywords or tags. I would pay handsomely to be able to block articles in newspapers containing words like Beckham, Posh, Sussex, Kardashian, Harry, Meghan, Caitlin etc., etc., and others.

If I try to use Messenger, I get an error message that I am not connected to the internet. This is just within the last 24 hours, but some are saying it's been doing that since the last update. Is there a setting that needs to be changed?

Hello! Since I updated Firefox to 118.0.1 (latest version when writing this) the Teams Large Gallery mode in Firefox is displaying black and eventually all the participants appear but the performance is 1 frame per minute. All the cameras are frozen and occasionally the display refreshes for one single frame.

Audio is working fine and default Gallery mode (only 4 camera displayed) still works normally.

Thank you!

I run a website that is custom built and we are seeing a potential issue in which the headers and header links are showing in the reader view of every page above the content for the page. But I'm also not sure if this is necessarily bad or might be affecting SEO.

Does anyone know whether this is detrimental to SEO, and if so, are there any suggestions on what might be causing this to happen in the code?

Recently random boxes (black, grey or white) started appearing when highlighting text. The problem started occurring after the most recent Windows 11 update (2023-09 Cumulative Update Preview for Windows 11 Version 22H2 for x64-based Systems (KB5030310)).

Have been fighting to get back to square one after an overly enthusiastic VPN system screwed up my browsers. Not just Firefox.

I needed to do a clean install. So I followed the instructions to delete the appdata/mozilla/firefox directory.

I don't want stuff to look the way it was before the install. I just want to try to put things back together to my liking.

Is it stored somewhere else? Is the existence of a backup known?

Why can't there just be a question: "Clean install or Refresh?"

It should not be this hard
