Many file types are no longer listed under Settings > Applications>Content Type at about:preferences#general. I used to be able to click on a file in an email like a Word or Excel document, and it would come up on my screen. Now Firefox asks me to Save them. I don't want to automatically save files without first looking at them. How can I get those file types in the Application list again?

I have attached a pic of the file types I have left to chose from. There used to be a lot more. How can I get back all the missing choices I have had there for years?

I am using Firefox 84.0.2 (64-bit) on Win 10 Pro and the menu font size and toolbar icons are minuscule, even on my 32" monitor.

I found a fix for this same problem in Thunderbird, but I don't see any way to make the menu fonts and toolbar icons bigger in Firefox. This has nothing to do with web sites, just the menu/bookmarks, toolbar icons, etc.

Thank you.

Hi, I am using the dark mode in firefox which is god sent boon to persons having glaucoma, with dark mode in firefox and dark reader add on. This was going well and after a recent update, I could not find it working. The dark mode is enabled and dark reader was there, but the browsing pages only shows in white. Has firefox changed anything recently to have this issue? If I miss something would the experts say, how to get back my dark browsing experience in all sites. If I find anything not visible in some sites, I used to go the windows properties and change the contrast theme to windows basic blue theme and then switched back to dark theme. this was helping the glaucoma persons very much. please, say how to solve this problem

I've been using Elijah Lopez's Matte Black (Red) theme for months. Recently, I think because I added the ClearURLs extension or some other change, certain websites enter some sort of "dark mode" when accessed.

Websites that do this include Twitter, an independent blog, and Youtube.

The website appears normally with the default light theme enabled. In the second photo, the website appears in the "dark mode" with the black Firefox theme enabled.

I have deleted cookies and cache, reinstalled Firefox, and reinstalled Extensions. I think this problem only occurs with dark themes, and nothing else. The moment I change to dark theme, the problem comes back. It is strange because the dark theme was working just fine for months until recently.

How can I keep the dark theme, preferably the same Elijah Lopez's dark theme, while using websites normally and not in this weird "dark theme" style adaptation?

This is driving me a bit mad...

A while ago the spellcheck in FF just stopped working. I literally only have a single add blocker installed that I've always used. I've not made any system changes lately beyond installing a few games.

- I have the "check spelling as you type" box checked in the browser options. - I have the English language pack installed from here (The British pack installed currently) - I've opened about:congif in the browser itself and made sure the value for layout.spellcheckDefault is set to 1.

It doesn't work on any site.

Chrome is working fine, but I prefer to use FF.

- I've tried reinstalling. - I've tried unchecking and rechcking the box.

Any ideas where what I should try next?

Any help really appreciated!

Every solution which I have found for Firefox 89 "Proton" so far which moves the Tabs Bar below the Navigation Bar (AKA "address bar"), with the Menu Bar above it, does NOT move the Tabs Bar below the Bookmarks Bar. The Bookmarks Bar appears to be overwritten and blank, and occupies space below the Menu Bar, Navigation Bar, and Tabs Bar. This empty space separates the three bars which are implemented and the content of the currently-selected tab below it.

Currently, my userChrome.css file is a copy posted by Corel-10 (?): __________________________________________________________________________________________________

Evidently, the text editor for this website does several things to the above original text that, frankly, seem unnecessary and undesirable. The .CSS file is just an unformatted text file, so what is the problem with simply copying its contents and pasting it in to the body of this post?

Which is also to say that I do NOT have a clue as to what any line in the file is meant to do, what effect it has, why it is even in the file at all, or why it is written in the way that it is. So DO NOT tell me that I "CAN" create a Cascading Style Sheet on my own when I cannot even modify one that has been provided. 

On the face of it, something is missing from the above CSS text. What change needs to be made to the above content so that the Bookmark Bar will appear between the Navigation Bar and the Tabs Bar??

Thank-you very much for your time and attention to this request for assistance.

I have read the same named question that has been archived and have not found a solution to my problem there. I'm using Macro Express to define my own keystrokes which works fine outside of FF. One of the keystrokes I have defined is Ctrl-Shift-k. A suggestion was to disable Developer Tools via about:config -> devtools.enable = false, but when I tried to use my definition of Ctrl-Shift-k, instead FF told me "You activated a Developer Tools shortcut. If that was a mistake, you can close this Tab." when in fact I wanted to have it invoke my own definition.

How can I override this (and other) keystrokes when using FF?

Firefox did an update today, so I assume this has something to do with it. Every time I do a download (and I do a lot) the drop down list showing the downloads I've done pops out. It didn't do this prior to the update. It used only to appear when I selected it. Now it comes out every blasted time. It's very annoying and distracting. To be clear, I still want to see the download arrow/indicator/whatever so I can see the download is happening, but I don't want to see the list each time. How do I make it STOP? Image attached. Thank you.

I'm already using Jscher's excellent UserChrome script to make the folders an attractive yellow, instead of gray. But can this be done for individual foders?

Is there a way to return to the more slimmed-down tabs and menus design of before? Because the latest update has all my menus double-spaced, and they're so bloated now that it's really hard to find anything with half the information spread out to take double the space.

To fix this, I have tried other users' suggestions of disabling proton, which had worked previously but no longer seems to have any effect as of the latest update. I have also tried the "compact menus" workaround, but that doesn't affect the double-spacing within the drop-down menus themselves.

I had Bing as my homepage and search engine, and that has always worked fine, for many years. But after a recent Firefox update, the browser will no longer allow Bing as my homepage and search engine, and because I had set the browser exclusively for Bing, I can't access another search engine. I liked the Bing homepage because it had a new photo every day, and most of those photos were downloadable to use as wallpapers. Looks like I may go back to Internet Explorer [I don't like Edge]. Why won't Firefox allow Bing now? - it's not a security risk.
