Firefox Support Forum

A few weeks ago a small link of the current page started appearing at the bottom of the page when playing videos on every website on every device that has Firefox. Ive seen this link before but it always goes away when I put the video in full screen. A temporary fix is going to another tab and switching back. This makes it go away until I see another video.

In the SharePoint library Setting is the desktop App defined to open M365-files. Chrome, Edge and Opera, open the files in the desktop App. Not so Mozilla Firefox: with this browser, the files are opened in a Tab, instead of the desktop App. Why is that? How can I change this behaviour?

It did'nt change with marking "Ask, how files are opened or saved With kind regards, Christian

URL links in Mac Mail have suddenly stopped opening when the Firefox app is not running. Clicking on a link will open Firefox, but will stay on the homepage and not continue to the clicked URL.

Hello, Fo years I've used native Firefox on my Ubuntu system (which is /usr/bin/firefox). Now I've switched to snap firefox, because it's the new way to use and update Firefox on Ubuntu systems. I used too an extension called Open with (https://addons.mozilla.org/fr/firefox/addon/open-with/), to open shell scripts when I right clicked on a hypertext link to use it in the script shell. Then the script did its job with the url link received in parameter. I know it wasn't the goal of this extension, but It did the job I wanted. Now, in the snap firefox, I cannot do the same. It seems its because native messaging (https://developer.mozilla.org/fr/docs/Mozilla/Add-ons/WebExtensions/Native_messaging) doesn't allow permission to interact with others applications (fix me if I'm wrong). I test several extensions, but I didn't find one to do the same job, and I've not the skills to developp it. Si here's my question: is there a way to do execute this type of script (not JavaScript) doing a right click on a link? Thank you for your help.

Though i did not log into any sites recentl, the status for all my saved logins indicate they were last used either yesterday or the day before. How can this be? Have they been compromised?

I think you just installed a new version, because a Firefox page popped up, and all the other pages I have open "stopped" working. Maybe because some extension stopped working? Actually a lot of extensions stopped working. I hope when I push the "share data" button down there it'll send you my extensions list.

"Stopped working" means sometimes nothing displays at all; I can't get white-on-black to work; other things I can't remember. This was working a couple of hours ago and suddenly it isn't. So, can you tell me how to back up to a Firefox that works for me?

P.S. I got a this-tab-just-crashed message while reading the troubleshooting info window. Luckily restoring the tab remembered what I'd typed.

Hello,

since yesterday I cannot use Firefox anymore; nothing works; cannot load any website when I can with Safari on macbook runnin 13.2.1 and firefox runs OK on my android phone. I have tried essentially all the suggestions I found on the Mozilla web site. No success. May you help me ? Thank you. Isabelle.

An XML document under a URI http://base/sub/document.xml uses an XSLT stylesheet under a URI http://base/sub/stylesheet.xslt. The server redirects permanently to http://base/stylesheet.xslt (response code 301). The stylesheet file contains <xsl:include href = "common.xslt"/>. Firefox fails to GET http://base/sub/common.xslt ?? Instead, Firefox should GET http://base/common.xslt (?). So, the base URI of a document under a permanently redirected URI is not the redirected, but the original URI ?

Hi

I wondered if I could get help understanding why a crash might be happening. Firefox seems to suddenly be crashing for a reason I can't determine. This crash was when I opened a YouTube tab, but it also happened on a Pinterist tab yesterday. I was running Firefox in troubleshooting mode on this most recent crash, which had the following id:

bp-5c36d424-6fc1-4fec-b56b-173b90230910

The only thing I've changed recently is moving some extensions from the main toolbar to the new extensions "puzzle piece" area, as well as switching from the default theme to the dark theme offered in the themes area.

Thank you for any recommendations.

My userChrome.css...

#main-window { border: 5px red solid !important; }

It's only half-working though as in first screenshot. I've tried messing about with padding & margins - to no avail.

The 2nd screenshot zooms in on bottom-left corner and shows a faint blue outline (shadow?).

Any suggestions on fixing the border?

Cheers.

Just recently I noticed that if I click a desktop shortcut or email link, it opens Firefox to the home page. The only way a shortcut will open the specific page is if Firefox is open already. This happens if I select opening a link in a new tab or new page. Again, this never used to happen until very recent.

Also, this only happens with Firefox on my Mac. On Windows, Firefox doesn't need to be open already in order for the shortcut to open the specific page.

I just filled all of this out. When I clicked on Submit everything disappeared and the boxes are now red. Really, I have to go through all of it again. Oy! The box with applications for my downloads used to have one or two or three. Now it has this; irc ircs JPEG Image mailto Microsoft Excel 97-2003 Worksheet Microsoft Excel Comma Separated Values File (application/ms-excel) Microsoft Excel Comma Separated Values File (application/x-csv) Microsoft Excel Worksheet Microsoft Word 97 - 2003 Document Microsoft Word Document ms-phone ms-settings ms-word onenote PNG Image Portable Document Format (PDF) Scalable Vector Graphics (SVG) spotify WebP Image zoommtg

What is Word 97-2003 doing there? Why is my phone an option? I didn't give Firefox my number. That's one problem. This issue makes my skin crawl. If I have to fill out a form on a new website all I have to do is type J and my full name, all of my email addresses, my physical address, and phone number appear in little boxes below the lines of the form. This is new and i really don't like it. Why, out of nowhere, is my information avaiblabe on the entire internet? If I hit Submit and these boxes turn a new color I will start screaming.

FF says "account disconnected" but I did not disconnect it.

Ok. So reconnect and launch sync. No problem. 4 other machines have FF and syncing works great.

See tabs etc synced just as I am used to from decades of happily using FF.

But close out and restart. WIN 11 new desktop.

Come back to FF and get "account disconnected".

Your thoughts greatly appreciated!

I'm having problems with CPU usage (and Mac temperature) after last update in the full screen mode (I use a firefox extention). It may be changed something in last update? When normally in my daily use of firefox I don't have any problems about my pc temperature. Plus it happens that the external links like the Zoom from Firefox to the application or the the "favourites" link pages I added on my dock don't work at the first click, but I have to wait firefox to open, after I click the first time, and then I can open the favourite from my dock

Hello,

Favicon is not appearing in Firefox Popup window though they are appearing in normal tabs. In Popup browser window it is showing the default Mozilla Firefox icon. I want to know if Firefox is not supporting Favicons for Popup windows or what we need to do make the Favicon appear in Firefox browser Popup window. I am using the following line of code for Favicon-

<link rel="shortcut icon" type="image/png" href="img/fav-icon.png"/>

With the same line of code other browsers are showing the Favicons correctly in Popup windows It just the Firefox having the issues.
