In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

I use Firefox Developer Edition and recently I noticed a problem when watching videos on any website in full screen mode. As can be seen on the attached image, there is a weird pixelated border around the video.

I have a problem where if I install the packages needed to get hardware video decoding working in firefox it completely breaks YouTube playback. I can't find any info on the internet about the problem and I am having a lot of trouble with it. YouTube playback with libva-mesa-driver and libva-vdpau-driver will start stop restart start playing audio then crash with a this error every single time. I am at my wits end trying to figure out this problem and I would love help figuring out the problem I am using firefox-developer-edition as a note thanks Ozzy

I haven't upgraded browser versions for a while and I'm now going from 109 to 132. Pretty bad I know.

I'm having a number of issues but for this post I'd like to concentrate on userChrome.css.

In version 109, I had a custom font for the top menu bar, the top menus, the bookmark toolbar, the bookmark toolbar menus, and the right click menus. I did this by including the following in userChrome.css (as per [https://support.mozilla.org/si/questi.../1335097|here]:

1. navigator-toolbox { font-family:"MyFont" !important }

This worked great, but it is no longer working in version 132. Obviously I don't know in which Firefox version this stopped working.

Has this been disabled by Mozilla or has it been changed? If it's been changed, how can I achieve it now?

I'm very grateful for any help!

I am trying to use a <select> tag to display a color selector. So each <option> has a background color to match its displayed text:

```<select id="strokeColor" name="strokeColor" style="width: 10em;">

             <option value="black" style="background: #000000; text: #FFFFFF">
                     black
             </option>

<option value="aqua" style="background: #00FFFF">

                     aqua
             </option>

<option value="blue" style="background: #0000FF">

                     blue
             </option>

<option value="brown" style="background: #A52A2A">

                     brown
             </option>

<option value="gray" style="background: #808080">

                     gray
             </option>

<option value="green" style="background: #00FF00">

                     green
             </option>

<option value="magenta" style="background: #FF00FF">

                     magenta
             </option>

<option value="orange" style="background: #FFA500">

                     orange
             </option>

<option value="purple" style="background: #800080">

                     purple
             </option>

<option value="red" style="background: #FF0000">

                     red
             </option>

<option value="white" style="background: #FFFFFF">

                     white
             </option>

<option value="yellow" style="background: #FFFF00">

                     yellow
             </option>

<option value="#000000" selected="" style="background: #000000">

                     #000000
             </option>
         </select>```

On Chrome this displays as expected:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-04-18-22-02-25-eebbd5.png

But on Firefox the background colors are ignored:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-04-18-22-02-35-bd90ee.png

How can I get Firefox to display the background colors?

I was set up, in myuserchrome.css, to hide my pinned tabs on the tab bar, allowing them to still be available in the "List all tabs" menu, see first image

.tabbrowser-tab[pinned="true"] { display: none !important;}

All of a sudden, it reverted back

That first image, with the hidden tabs, is actually from Librewolf, with has the identical setting.

Autofill has been working perfectly fine until yesterday. There's not even a manage addresses in the privacy and security settings anymore.

Autofill card still works, but not addresses.

New addons on Firefox become blank on restarting the browser.

They return when I manually disable and enable them once.

How to fix this? Doesn't happen to older addons.

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

When I open Firefox. Firefox Will NOT open any websites. If I disable ublock origin then enable again Firefox works but I get all the ADS. What I have to do is: Close firefox and restart Firefox but then I get this message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." Sometimes I have to restart Firefox as many as 10 times before Firefox works. I got to the point where I stop after the second try and just switch to Brave browser.

Before: Firefox use 99%. Brave Use 1% Now: Firefox use 75%. Brave use 25%

Dear,

I have been using Firefox Developer Edition for many years without any problem. I sync Firefox on my different PCs, so they are basically all the same in setup. Unfortunately, Firefox now crashes constantly on my main PC. I have therefore temporarily switched to the default FF variant.

Of course I have tried all the steps shown here on the forum but without any result that I can see. Both in safe mode with or without addons. No matter FF crashed.

The error ID: Crash ID: bp-20d91ca4-1f79-4211-a3d5-4fd7c0240507

I hope someone can help me on my way ,

Regards,

Reinder

Last few days any Firefox 102.0.1.8221 launch causes my Windows 7 64bit to reboot, usually when I try to mouse click anything in Firefox after it's fired up and restored open tabs, however even if I don't mouse click anything Firefox will force a reboot within a minute or so.

This Firefox Win 7 reboot behaviour only started after the last Firefox update, though I would point out that around update version 100.nn I started getting failed update notifications from within Firefox which necessitated a manual newer version Firefox download and install.

Running Windows 7 in safe mode with networking on allows Firefox to function without crashing, albeit slowly and with no MSE protection available etc.

Only one crash report dated 16/07/2022 with following content: Crash ID: bp-d8383165-9c77-45e4-9929-a3ce12160527

Please note I'm sending this report via Firefox on my iMac coz that still works...

When selecting "Open in Firefox" in the "What do you want to do with this file?" box or on about:preferences and then opening a PDF file on the web, instead of downloading the file to RAM and opening it with its online address, Firefox downloads the PDF to /tmp/mozilla_${USER}0 and opens it from there. This also adds it to the download history. I have set the about:config flag browser.download.start_downloads_in_tmp_dir to true so the files I just open and don't want to permanently download don't clutter my $HOME/Hämtningar (downloads) folder. I tried to first prevent that by selecting the default action to do when tasked to open a PDF, but that didn't fix it, so I set the about:config flag. Unfortunately, setting the default action stopped Firefox from opening a PDF inline without downloading it and I cannot find any option along the lines of "Preview in Firefox" (as described in this support article ).

Thru Firefox, I use Tineye to find related photos - I use it all the time, it's been great - I always use a VPN and have never had problems until now (as of yesterday). Now it won't search, a verify you're human window comes up, and I have to keep clicking squares, which I do - but then it says to allow cookies and start over. Well I don't want to allow cookies (I assume it's one of the options I have thru Firefox to block cookies), and I can't find where to allow cookies even if I did (I went to Firefox preferences etc) and I don't want to disable my VPN. Maybe I should mention that I just added or started a Mozilla account, as I have had immense trouble with my aol emails, and am trying to move everything over to a gmail account. My sign in to Firefox was the aol email, and I had to (try, I thought I did it) add another account, which I think I did successfully. So it was right after that, that all this started. Help please! Thank you!

I just updated to Firefox 120, and tried the new GPC setting (Tell websites not to sell or share my data). I ran into a problem when I went to the Xfinity community forums (https://forums.xfinity.com/) . It causes a banner on top showing they recognize the setting. There is an "X" in the corner, and some text that says "Hide this banner", but they are not active. Plus, I cannot make a new post or do a general reply (that weird forum software has both local replies to a particular post and general replies to the general thread.)

Is this a bug in Firefox, or a bug in their forum software? I attached a picture of the message it gives.

Whenever I try to open Firefox, it takes about 25 seconds to boot. This behavior can be observed both with all the extensions running and in safe mode. The link to the profiles are shared below.

With extensions: https://share.firefox.dev/3riMPQZ In safe mode: https://share.firefox.dev/3OadE31

I have been noticing this for a few months now. Firefox works just fine after wasting ~25 seconds initially. I have also reinstalled Firefox multiple times. Right after the installation, the boot-up can be very fast (less than 1 second). However, after using Firefox for a few hours, the problem comes back.

I am not well-versed in reading Firefox profiler reports. So, please help me figure out what's actually happening in those ~25 seconds.

A few days ago I was downloading a ZIP file and was warned that "This file contains a virus or malware". Fine, thank you for telling me but now how do I seeing the same warning every time I start Firefox? The file in question does not exist on my computer so far as I can tell and I did a thorough search through 3.5tB of storage on the machine to make sure. How do I stop this warning?

On all sites where I need to login with my work account I get a tab crash when the browser redirects to https://login.microsoftonline.com/ac4b0eb0-811e-4ab0-acca-8a87079290dc/oauth2/v2.0/authorize?response_type=id_token&scope=user.read......

This is a recent failure (this week), that occured without any changes on my own account to Firefox developer version 121.0b2(64-bits)

I had to install google chrome to overcome this problem. Chrome has no issues with microsoft authentication.

Please solve as soon as possible, otherwise I will be switching to another browser.
