I had set up a userContent.css file in the past to pull up and fetch an image on my computer to display as a background on the homepage. It worked and did it's job until recently, when I had recently relocated a lot of my files around on my computer. I have redirected everything to where I want it to look, including the userContent.css file to the new location for the image I want as the background. Firefox loads the .css file correctly, and recognizes the file existing, but it won't load the image itself for some odd reason. It states it "may not load or link the file" because of a security error, and thus, can't load the image. I never had to deal with this before. How can I get Firefox to be able to load my image like I want it to? I have screenshots that I can provide, but this site doesn't want to upload them at the moment.

Win 10, Developer Edition 103.0b2

This update caused everything to increase in size. Tabs & toolbars are much bigger now. Toolbar and bookmarks toolbar used to fit in the window with no overflow, now both have a lot of items in overflow.

Sites that used to fit at 100% zoom now have to be reduced to 80% or 67% to fit on-screen.

Just wondering what could cause this behavior? Settings?

Note: Browser window is fully maximized and no other program on my Win10 box has this issue.

Hello,

Whenever I use Firefox, I end up seeing popups (necessary for school) and would like to show them as tabs so I can merge them into other windows. I have tried the solutions given in: https://support.mozilla.org/en-US/questions/1080255 and nothing seemed to work. Is there another way to make sure that popup windows cannot hide the toolbar and show tabs?

Downloading and Opening docx Firefox appends doc onto file

I am using Hotdocs portal, which is an in-house document assembly tool. Firefox is the recommended browser, but it is recently handling 2016 docx files incorrectly. When we choose a file on the portal site (internal site), we go through the interview and are presented with a link to "download" the assembled file. When you click that link, a pop-up appears showing the file name as abc.docx but then says it is a Word 97 - 2003 document, even though it is not. The original template is not. If I choose to open the file, it ends up opening and showing as abc.docx.doc If I save the file, instead of opening it, it saves as abc.docx.

If we run this same process in IE/Edge, the file opens as abc.docx as it should. I have uninstalled Firefox and reinstalled. Is there anything that could be causing this? I've tried a bunch of troubleshooting steps and nothing seems to change this outcome.

Thank you.

In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

Hi everyone,

I am having trouble getting my custom new tab page to be focused when opened (instead of the address bar).

I am currently using the `autoconfig.js` + `mozilla.cfg` approach to overriding the `AboutNewTab.jsm` service with a custom local file. This is working great with the two files containing this code:

autoconfig.js: ``` pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0); ```

mozilla.cfg: ``` // Custom firefox config

let { classes:Cc, interfaces:Ci, utils:Cu } = Components;

try {

 Cu.import("resource:///modules/AboutNewTab.jsm");
 let newTabURL = "file:///home/vallode/Documents/test/index.html";
 AboutNewTab.newTabURL = newTabURL;

} catch(e) { Cu.reportError(e); } ```

I have been attempting to use the `gBrowser` global to add an event listener to the new tab opening, but with no success. Could anyone point me in the right direction for something like this?

I've tried to install several search engines via Mycroft Project to use them through the search bar but that doesn't seem to be working.

I don't get any notice, it just doesn't work.

Also, one of the search engines I've been using (Twitter) seems to have disappeared from my browser. That's what got me to try to install it again, with no luck so far.

(I've dowloaded Firefox Nightly, installed it from scratch, and seem to have the problem.)

My OS is Windows 10 Pro Version 2004 Build 19041.329

I'm using Firefox Beta on a slow laptop in Linux -so, manually changing videos to 360p from the cog works to make them play smoothly. The facebook SD Only setting in https://www.facebook.com/settings?tab=videos doesn't really work -only in a few videos. If anyone knows of an extension that handles this on latest Firefox Beta let me know. Thank you.

When I try to checkout on a site using Shopify, the credit card fields are unusable. The form fields turn into animations, almost like an animated GIF and will not stop. It is difficult to describe what is going on. Here's what it looks like:https://i.imgur.com/mTJfDeD.mp4. I don't know how else to illustrate the issue. This has been going on for the past several versions of Firefox. I'm currently using 79.0b3 (64-bit) on a Mac.
