My main screen and drop-down are stuck in a black background. I have changed the setting but they only work once I leave the home screen that shows in a new tab. How do I get it back to a white background?

I use Firefox to develop my organization's CMS, which uses HTTP Basic Auth. This stopped working suddenly - no basic auth prompt is shown as of 16 Feb 2022. There's no error in the window or console, my server logs a 401 as expected but I've no way to log in. It works fine on other browsers.

Presumably, this is due to the fact that the CMS runs on HTTP, not HTTPS.

Is there anything I can do? We need to keep this running on port 8080...

I use to be able to change firefox icons by adding these files in Firefox under the browser directory

I have Firefox version 97.0.2 (64 bit) for Windows. Lately, every time I start up the browser, it's trying to install an update. I haven't had this problem before with Firefox (and I've been using it for several years now). Is there something I need to do to stop this?

I just installed Firefox version 97.0. After the install, my print preview disappeared! Solutions I found on your web site DO NOT fix the problem. I change the configuration entry print.tab_modal.enabled from TRUE to FALSE as recommended.

Also, there is no entry app.normandy.startupRolloutPrefs.print.tab_modal.enabled in my config.

Please help!

I've just started using Firefox as my browser and really like it, but I am unable to open various items (bank statements, etc) when I go to some of my websites. No problem when I use Chrome or others. Can't find anything to change in Firefox settings. Very annoying. How to fix this?

Hi everyone, I have created an extension that can be used from the usual position at the top right through which you can do some things, including open a website locally. To be clearer ...

Extension Folder: - extension.js - manifest.json - LocalWebSite (folder)

Inside the LocalWebSite folder: - index.html

Then clicking the button via the extension will load the local website. At this point, when the local website is opened it becomes impossible to trigger any button, modal, or whatever, it's a totally static page.

One important thing is that I don't want to replace the popup with the static page, I wish I could have both.

Extension Code: // SiteWebLocale function openWebSite () {

   browser.tabs.create ({
       "url": "./LocalWebSite/index.html"
   });

} document.getElementById ("openWebSite"). addEventListener ("click", openWebSite);

Local Website Button Code (It doesn't work): <button type = "button" class = "btn btn-danger" onclick = "alert ('ok')"> Action </button>

I'm not sure this is a problem with Firefox but I have run out of other options to look at. At first I thought it might be because the page uses a frameset (I know it's obsolete) so I created a version that uses an iframe instead. That way the html that needs to be acted on is not in a frame. It still doesn't work. I don't know why it works in stackoverflow's sandbox and jsfiddle but not on my website. Any help is appreciated.

Frameset version iFrame version

If you need to see the tabstrip code (it's virtually identical to the iFrame version): Tabstrip for frameset version

The script is supposed to hilite the selected tab with a red background. The rollover works fine (yellow background and brown text) but the selected tab color never shows up.

1. Firefox for MacOS prompted me to "REFRESH" 2. After "REFRESH" Firefox is missing all my previous data (bookmarks, history, passwords etc). 3. "Old Firefox Data" folder is on the desktop 4. I have followed archived support help steps for this issue but did not restore previous Firefox profile. 5. Archived help solution says to ask the question again.

I use many tabs open in 97.0.1 . They are grouped by subject. When I do Duplicate Tab instead of adding tab directly in next location I find a large number of tabs copied and moved to end of line. Restarting Firefox has all additional tabs removed and original tab is not Duplicated. I resort to adding new tab at end of line and dragging back to position I want then copy/paste URL. Problem has occurred in last few upgrades.

Hello, I accidentally removed my "save bookmark" star (that turns blue when a page is saved) in the address bar. I know there are other ways to save a bookmark but I want it restored as it was. What should I do for that? Thank you.

I have two PDFs that I designed and uploaded to our website, but the headline in both displays with clipped characters in Firefox. Different fonts were used in both and the issue is the same. I even tried adding more tracking then re-uploading, the issue persists.

I checked in other browsers and the text displays as intended. The attached screenshots show the issue in Firefox, compared to how it should look (viewed in Chrome).

It's only this one line of text that is affected and I don't know why.
