i am using firefox on a Linux debian based distro, I am facing difficulties changing the size of the menu e.g width, height and font. I have tried to play with the about:conf > layout.css.devPixelsPerPx value but that did not change a lot for the menu size. so please tell how can I fix this (I am trying to make it smaller) note it is same case when I use firefox-esr for linux as well.

When using the official 'Dark' theme, some things like the home page change their theme to dark.

When using a 3rd-party theme, how can I get the same dark theming?

I tried comparing the prefs.js file with official Dark and Light themes, but didn't find any meaningful differences.

For whatever reason, with the latest release, it seems like videos on YouTube produce a white rectangle when hovering over them with my mouse. See image for example.

I have tested without add-ons and the same issue persisted.

I have tested with another browser and it was working fine.

Thanks Have a great day

Today firefox prompted me to upgrade to the latest version, i upgraded to 75.0, then a problem began with youtube. whenever i hover the mouse over the video window the progress bar comes up with white background instead of being transparent as usual, and that huge white bar hides half the video window. i attached a picture, in the top the video is normal when the progress bar is hidden, but when i hover the mouse to bring the progress bar this white monster bar comes up and hides half the screen. the exact same thing happens when the video is full screen too.

i tried removing all plug-ins and extensions, it still happened.

i cleared cache, history, cookies, it still happened.

i logged off completely, it still happened when i played a video without being logged in.

i started firefix in safe mode, still happened in safe mode.

chrome, opera, and edge work alright on youtube. only firefox following today's update. Any help? Thanks

It looks like Firefox has the wrong user-agent set. I've made a few changes to about:config that I found on privacytools.io but none of them had anything to do with the user-agent. I read through Mozilla's "reset the default user-agent" article but none of the mentioned settings are in my about:config so there's nothing to reset. I would create them myself but I don't know what they should be set to (the article only says to click the "reset" button next to them). I'm running Ubuntu Linux but it seems Firefox is telling websites I'm running Windows...for proof see the screenshot attached to this post.

Hmm...it seems this page detected that I'm running a variation of Linux although no other pages (such as the one in the screenshot) could. What can I do?

Edit: it looks like this page says my user agent is correct (it shows Linux), however many many other sites on the internet say I'm running Windows. I'm really confused now.

I very often have to visit a (company internal) webpage where the url is something like

        https://internal.company.com/blabla/whatever?func=test&id=XXXXX

where XXXX is changing (it's a document identifier)

Now I'd like to be able to reduce this to something like "a XXXXX" and to have firefox to automatically expand this to the full link. It's a bit like a custom search with a keyword. Is this easily possible?

Hello, i saved many website pages using scrapbook and firefox mac v56, this addon seems to no longer exists , i was aware that it was not supported in firefox v.quantum but i had no idea it was taken down and woke up to this today.

the addon web-scrapbook seems dodgy, you have to create an account and use a cloud server contradicts the whole idea with scrapbook which was about saving webpages to read them offline.

can anyone ease advise on a solution to this?

I have consciously transitioned from Chrome to FF for Privacy reasons, but find myself with a problem now. When i close the browser i have set it to delete all the cookies. I want however to make exceptions for certain sites like i did with Chrome so that when i go back to LinkedIn or YouTube i don't have to go through the 2-step login process which is quite annoying if you have to do that multiple times per day as you can imagine. not having been able to find a definite answer on how to do that (yes, i did read multiple support articles) i turn to you to for help Is there a whitelist option to handle exceptions per domain for deleting cookies?

I have a site created through wordpress platform. I have used page jump (anchor) to redirect one of my links into a specific section from another page. Works fine with Chrome, IE and Microsoft Edge, except with Firefox. It redirects to the page but gone through the bottom of it rather than the specific section where it's suppose to land.

The following code work in Firefox v54, but stopped working on Firefox v68.4.1 (possibly earlier version as well).

index.html: <body>

<object type="image/svg+xml" data="test.svg", id="test_svg_id">

   Your browser doesn't support SVG
</object>

<script type="text/javascript" src="test.js"></script>

</body>

javascript: function init() {

 console.log("init()");

// Get the overall SVG defined in the Index HMTL page var svg_object = document.getElementById("test_svg_id");

// Get the SVG document inside the Object tag var svg_document = svg_object.contentDocument; }

Any idea why contentDocument is always null?
