browsing website (reddit or amazon for example), the window scrolls to the top every time I move the mouse. doesn't happen all the time though, and only in Firefox. I've serached the internet and can't find anything related. Please help

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

mouse pointer is nice size in general but becomes VERY small when I go into websites. this happens when i use either floorp or firefox but is fine when i use chrome( would rat5her not use google). i just don't see where I can fix this in Firefox settings

I have started posting bugs of Firefox in Bugzilla for almost 6 months now(though the number of bugs is 3). I have noticed that the bugs really had no response for nearly then(almost 6 months), so is it the way bugs are handled?, like they take long time to address( just asking as I though the process to be relatively fast) or is it something that I might be doing wrong in reporting a bug. I searched online and have been looking at assigning the bug( what I understood). So, how to do it if there exists something like assigning and will it increase the movement on my bugs??

I'm new to firefox and would like to set cloudflare for DNS over HTTPS but there seems to be an issue. If I set it to NextDNS the connection stays active. But if I set it to cloudflare it goes inactive with the error (NS_ERROR_NET_TIMEOUT_EXTERNAL). I tried setting a custom DNS to OpenDNS and got the same error.

I'm running Manjaro Linux if that make a difference.

When the little yellow man is placed on to the map, and a direction arrow is clicked, the view just continues to spin round. Clicking on the 'X' in the top right hand corner terminates street view. This does not happen with other browsers.

My OS is Debian 12, Firefox is the latest version 115.9.1esr (64bit).

Firefox can take screenshots of pages or screenshots of custom areas of pages.

According to the documentation, when we download the image, the filename should follow the pattern: Screen Shot yyy-mm-dd at hh.mm.ss.png. If I use the :screenshot at the console, the pattern works as documented.

But Firefox is using a different pattern when I choose Take Screenshot from the context menu. The pattern includes the page's title. Example: Screenshot 2024-04-14 at 18-35-16 General ‹ Settings ‹ Geomaster Lda — WordPress.png.

Since the page title can have non common filename characters, I have problems with such filenames. My uploads to MediaWiki fails with such filenames. I know I can report or improve MediaWiki, but my question here is quite simple.

Can I change the Firefox's default pattern for Take Screenshot's downloads?

Hello

I want to use extension xpi's from a shared external folder over multiple Linux profiles. So i examined the profile folder and found extensions.json. Though i can't find any documentation to it's keys online.

There's "rootURI:" with a "jar:file://path/to/extension.xpi!/", so i tried just replacing the path with the shared one. Though i observed that just makes firefox replace the path with the current one. So i examined further and found the "location:" key with the default value "app-profile". So my guess is, there's other values for other usecases, right?

So, in summary, what i need is:

• documentation to extensions.json keys or possible values to "location" key.
• if that isn't intended/doesn't work, how i can achieve my goal otherwise.

And please don't suggest the sync feature, that doesn't work for my usecase.

Currently, I use Firefox version: 116.0.2 or v117.0 on Ubuntu 20.04.6 LTS.

I encountered a phenomenon like this:

• When I logged in to the application, in the tab I was working on, the Firefox session memory was lost (don't open new tabs)

Steps: 1. Login to the application 2. Operate on the screen 3. Navigate to other URLs, but still on this tab 4. Session storage was lost

What is the cause of this phenomenon? How can I fix it?

When I pause a video (any site) and go to another tab / stay on the site, after a seemingly random amount of time the video starts playing again.

I'm using latest Firefox on Ubuntu 22.04 (snap).

I've tried (didn't work):

• Disabling media hardware controls through about:config
• Disabling autoplay through about:config

latest 124.0.2 causing severe problems, it will near instantly bloat to fill all RAM and SWAP even in safe mode causes system load over 24! only solution is to reboot very problematic on for ex: https://epg.pw/xmltv/epg_CA.xml hard to get a screencap since system is nearly totally unresponsive. RAM is ok SSD is ok MX Linux is ok

Hello, have been scratching my head for a while on this one. Have a freshly setup install of Debian 12, using Sway (wayland) as my Window Manager. I am really struggling with slowness in Firefox, page loads take easily 15 seconds whereas loading the exact same page in another window at the same time with Chromium Debian build has near instantaneous load times. I've tried the following troubleshooting steps: - Created a new firefox profile - Tried "Troubleshooting Mode" in Firefox - Disabled ipv6 in firefox about:config and in Debian - Tried different DNS servers - Tried different non-debian specific builds of Firefox - Tried Firefox Beta and Firefox Nightly for Debian

None of these steps made any difference, and Chromium has continued to be significantly faster. Am really stuck here and would love to get to the bottom of this as Firefox is the only browser that works with a HiDPI display in Sway without blurryness. Happy to provide any and all diagnostics and reports that are needed. Thanks in advance!

EDIT: It seems to be some kind of networking issue, using a VPN solves it. But still doesn't explain why Chromium would behave differently.

Could you add a option of closing tab with <kbd>Ctrl</kbd>+<kbd>w</kbd> to the advanced preference?

Also, I realized that:

```browser.tabs.warnOnClose False``` Does this option activates warn when closing the tab? If your answer is yes, it is not working at all.

I have run into an annoyance where I am trying to click on a link in my email to open a new page. Clicking on the link makes a bar show up telling me that Firefox has prevented a popup from being opened (see attached image). I am given the option of managing my preferences / Firefox settings, where I can either go through multiple steps to permanently allow all pop-ups from that website until I restore my original settings, or uncheck a box to permanently allow all pop-ups from all sites until I check that box again. This is annoying because I have no interest in either allowing or disallowing all pop-ups from all websites, or all pop-ups from this specific website, every time I want to open a single pop-up from a specific site. I would rather that the warning bar which tells me that Firefox has blocked a pop-up also display a button allowing me to allow ONLY THIS SPECIFIC POP-UP IN THIS SPECIFIC CASE.

Is this a setting that exists in Firefox? Alternatively, is there a version of Firefox which does have a setting which would allow this? Or is this simply not a functionality that exists for this browser?

I'm trying to migrate from Chrome to Firefox browser. I cant load Twitter and some other links. I get error message. JavaScript not enabled. I can't find a setting anywhere to enable it. Help!!

I'm having a problem sharing websites with others via, for instance, Signal. Telegram, WhatsApp or a social medium. There used to be a share button in the toolbar, but this I cannot find anymore. At some time there were also the three dots in the address bar that dropped down a menu for the page, which included a 'share' option. These dots seem to have vanished. Also I vaguely remember that the "share" function was also in he tab context menu once upon a time. However dropping down that menu does not reveal any "share" function presently. Then there was, if I remember correctly, the possibility to click the File menu at the top of the screen and then click on the Share menu item over there. But also there the "share" function seems to have vanished. I also looked in the settings menu, to find if there is a setting there which switches on or off the sharing function. I could not find such a setting. In short, it seems that I am horribly overlooking the "share" function. Please help me find it. Thanks. (Firefox 112 for Manjaro Linux)
