Firefox Support Forum

I have an extension called Gesturefy that allows you to use mouse gestures to do things like navigate through tabs, perform searches, etc. The problem is that on Mozilla pages, these gestures are not allowed for security reasons, as the developer explains: "Gesturefy does not work on Mozilla related pages like addons.mozilla.org, internal pages like about:addons or other add-on option pages (e.g. moz-extension://*). This is because Firefox restricts add-ons from accessing these pages for security reasons."

Is it possible to disable these restrictions for this specific extension or in general?

I managed to change colors of almost everything in my firefox browser but despite selecting dark mode and trying all different options in firefox color, all the menus just refuse to not be white. So my question is how can I change color of all the menus (file, history etc.) to be anything other than white?

Firefox has recently (within about a week or so) begun to crash randomly for me when switching between open tabs. The problem can be reliably replicated with ~6 tabs open, while quickly cycling between them. Firefox has been updated, and the crash still occurs even in troubleshooting mode. The most recent reported crash is Crash ID: 54793083-0841-470c-ae8a-687030240105. The flagged 'Crash Reason' is EXCEPTION_ACCESS_VIOLATION_WRITE

After a crash earlier today within my 32bit install of Firefox, I upgraded to the 64bit version. Since then I have not been able to play videos from sites that utilize DRM.

I have tried the following:

1. Check and Uncheck "Play DRM content"
2. Check for updates while in the addons related page.
3. Checked my hosts file which is blank
4. Stopped my AV and attempted to update as well as Enable/Disable Play DRM
5. Get a 404 when attempting to go to "redirector . gvt1 . com" site.

When I looked in my profile directory, I noted that both the "gmp-gmpopenh264" and "gmp-widevinecdm" directories are empty. I found and downloaded the most recent openh264 dll for windows 64bit. Firefox continues to say "OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly." I have not found the most recent wildevine version so I have not tried to update it manually.

Could there be something squirrelly with my user profile that needs to be rebuilt? (I can export the bookmarks, etc) The 32bit Firefox crashed with no messages while watching a live YouTube stream. I just installed over without uninstalling the previous version. I was afraid of losing my current settings. The crash caused my "previous session" to be lost.

I've got my "homepage and new windows" setting set up with several "ext+container links so that my selected websites open in their respective containers : e.g. ext+container:name=Personal&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor

I open facebook in 2 seperate containers so that I can maintain 2 seperate personalities under facebook - e.g. I am a group admin within one, just a group member in another.

I have 2 urls defined in my "homepage and new windows" setting for these :

ext+container:name=Personal&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor ext+container:name=Facebook&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor

This was working fine without any issues. My sites opened up when I started my web browser and everything.

Recently, firefox has started up but my container tabs do not load automatically, I am getting a confirmation (I will post a screen capture as a comment).

Is there a way to turn this off and just open the tabs without a confirmation?

Hello

```

~ /Applications/Firefox.app/Contents/MacOS/firefox-bin

[1] 5919 killed /Applications/Firefox.app/Contents/MacOS/firefox-bin ```

Can't event imagine how to debug this - FF has stopped working totally from the command line, despite options etc It is still working when run from the dock however. But I need to start it from the terminal for the second profile

Hello,

For a long time, I was able to launch Firefox on Windows with the startup switch "-private" which would cause it to launch directly into private browsing mode. I used that in a few local scripts, and created a shortcut to the executable, with this path:

"C:\Program Files\Mozilla Firefox\firefox.exe -private"

Just like that, it worked. Whether by shortcut, terminal command, or execution of a 3rd party script, that startup switch would always open a private browsing window. Until a few months ago, that is, when it suddenly stopped working. Rather than opening a private browsing window, it now does one of two things:

1. If FF was not already running, it opens FF to a tab showing a warning that I am not in private browsing, with a button I can click to launch a private browsing window. (see attached image) This tells me it recognized the startup switch, but...refused to honor it? 2. If a FF window is already open, it launches another (non-private) Firefox window, with no warning about not being in Private Browsing mode.

Was this an intentional change? Is that startup switch just not supported anymore? I tried a quick web search, but all I was finding were unhelpful suggestions like "right click on the FF icon" and "pin to start." Not what I'm looking for.

Thank you!

hello :)

in chrome when you drag a tab out to open it in another window it automatically goes to a smaller window, firefox always copys what size the window was when you dragged it out. so when the window is maximised it will always open a new maximised window.

So my question is, when dragging a tab to open it in a new window is there a way to stop it from copying the size of the window you dragged it?

im really bad at explaining things so here are visual of what i mean - https://imgur.com/a/aSj0P2G

I'm at a loss for words here. I have a website I frequent and it has a really annoying behavior. I'm a developer so finally I mustered the strength to do something about it. I googled how to create an extension in Firefox and within 5 minutes I had a working extension that solved their annoyance. However, I can only load it temporarily. If I close Firefox, it goes away. When I try to actually install it, it says I need to have it signed. I have now spent the better part of an hour trying to find out how to self sign it. I refuse to believe that I have to submit this to Mozilla for me to be able to install my own code. Can someone please send me in the direction of how i self sign and install my own extension. I have no intention of publishing, I only want to run this for myself.

I'm trying to open a web page, which worked perfectly until about a week ago. The address is: https://xdaforums.com/f/xiaomi-poco-x3-pro.12163/

I now get a popup window, which tells me that I'm trying to open a "application/octet-stream (377 bytes)" and gives me the option of "open with" or "save file".

I don't want to do either, just view the page as before.

I have just encountered another of Mozilla's unwanted, unneeded changes.The three simple little characters that almost all programs show in the upper right hand corner on the screen. These are long standing and well understood icons that were easy to use to manage your windows. Need to switch between program windows? Press the - key. Need to enlarge the screen to its fullest, press the open box, finished working with this program/screen, just click the x-box. Pressing the "open box" would adjust the screen so you could use the cursor to make the screen the siz you needed.

It's not just that these features work and are understood, Mozilla makes changes with no explanation, no other options for doing the same thing (exception: I can close the window with File> Exit (or Close)

I just spent a week getting Thunderbird115+ to "work" and now I have to figure out how to recreate what I've lost on Firefox? Like other people seeking support have said, I want the Firefox I know back.

I do not care about MSNBC, I just want to know why I cannot live stream on MSNBC in case I run in to other channels that may not work I would like to solve the issue or I guess I can just uninstall Firefox and call it a day if it is just the browser.

The audio does work, but the video is the start up or splash photo for MSNBC

Firefox will stream on NBC and I can stream MSNBC using Chrome and Edge.

I resent all of the setting in Firefox to default, and I turned off all of the extensions.

I was trying to get sync to work, I go to sign in and choose my google account, then I make my password for sync, when I press "Create Password" it just tells me "Unverified Session" in a red bar on top of my email, did I do something wrong?

I installed (as always) the new Windows 10, downloaded from the office. firefox website. I log in to my login, synchronization takes place (firefox says so) but MY data is NOT!!! no synchronization, no loading of passwords, addresses, extensions!!!

Is it still possible to configure userChrome.css to have the URL field in the Firefox 'Add bookmark' window? Also, is userChrome.css configuration going to be used no more in future releases? If yes, then how will we be able to customize, for example, fonts in Library, side bar and context menu?

I went to a normal retail website, and got this page that appeared to be from Firefox, telling me to download an add-on for security. I declined. but now when I try to go to that website, I get re-directed to some strange websites. How do I fix this?

I loaded the postcode lottery website but it's completely blurred. I last checked the same website last month, and it worked fine. I have cleared the cookies from Firefox, but the result is the same. It appears clear for a moment, then blurs. No pop-ups asking to accept cookies. It works fine using Chrome. Any idea why Firefox won't display it properly? It loads the National Lottery website, so it's not about gambling sites I guess.

One website in particular is almost 100% black. I cannot see most text. On another site, I cannot see check boxes, can't see the trash can icon.

This just happened recently. When I switch to Light Mode in the settings, both sites remain dark.

What settings can I change so everything on a site is visible?

There is a problem logging into Disqus. (disqus.com and disquscdn.com)

This is affecting Linux and Windows installations.

Page I'm having problems at www.lawyersgunsmoneyblog.com

I have used the troubleshooting mode and caches have been cleared and all extension disabled with no luck.

Other browsers are functional. The log in doesn't appear at all:

Hi. The annual NORAD Santa Tracker website does not function properly under Firefox. While there are no issues with the 3D rendering itself, the 3D map is squished vertically toward the left side of the page. It appears to be defaulting to a mobile browser view. The only extension I have installed is uBlock Origin, and I turned it off for the NORAD Santa website, and the display issue persists.

Opening the site under Safari shows the Santa tracker taking up the entire browser window as it should do.

I'm currently on Mac OS Sonoma using the latest version of Firefox 121.0
