Until FF100, I used to disable <Ctrl><W> (close tab) by modifying browser/omni.ja, commenting the following line out in chrome/browser/content/browser/browser.xhtml :

<key id="key_close" data-l10n-id="close-shortcut" command="cmd_close" modifiers="accel" reserved="true"/>

It worked until FF100, but doesn't work anymore in FF103 : commenting that line out seems to have no effect on <Ctrl><W>.

Does anybody know why ? Or does anybody know a way to disable <Ctrl><W> ?

Background : on French keyboards, the <W> key is right next to <X>, so when I try to do a cut/paste (<Ctrl><X> → <Ctrl><V>) I sometimes end up doing <Ctrl><W> by mistake, thus closing the tab. Re-opening the tab doesn't always do the trick, sometimes the latest work is lost.

I am trying to set youtube to always open in Youtube container , when i right click on the logo or name of the container it doesn't do anything , at previous version was fine , is there any issue with current version ? is there another way to enable youtube to open always in it's own container ?

Hi,

I am testing v102esr of Firefox for a rollout in September.

One of this issues I have come across is the extremely high number of processes started when opening Firefox.

We have our own website run via Windows Server using IIS. The home page has no remote content - it's all local so I don't believe any remote content is being opened. There is only one tab open.

For each new tab I open I get at least one additional process. So with 10 tabs opened I ended up with 24 processes.

In FF91esr this was 3-5 processes. I also noticed under performance settings I can no longer specify the number of processes.

Is there any way to reduce this number to something more sane, like 3-5?

Also, why is there a Console Window Host running under Firefox?

Is the Node.js also new? I don't recall seeing it before

thanks

I have noticed recently that every week or so my Firefox browser will randomly change my homepage directory to the landing page / search for MSN, which is baffling, since it is obtrusive and anti-Mozilla to me.

If y'all are sneaking it in for that sweet ad revenue, I understand, but I would donate to avoid this issue.

Otherwise Firefox / Thunderbird are awesome, and I appreciate all that you do!

Cheers, Elliot

How do I add a site in setting - camera permissions to allow it to use my camera and microphone while still blocking other sites from asking to be allowed to use it.

Duplicate. See https://support.mozilla.org/questions/1385117

Many file types are no longer listed under Settings > Applications>Content Type at about:preferences#general. I used to be able to click on a file in an email like a Word or Excel document, and it would come up on my screen. Now Firefox asks me to Save them. I don't want to automatically save files without first looking at them. How can I get those file types in the Application list again?

I have attached a pic of the file types I have left to chose from. There used to be a lot more. How can I get back all the missing choices I have had there for years?

I had problem with Firefox. He was slow, i reseted, but my addons disappear. Now i have problem, i can install any addon's. Doesnt matter, official or unofficial. I cant anything. Firefox was again reseted, uninstalled and again installed. No matter what i do, come this massage:

"Installation aborted because the add-on appears to be corrupt."

I'm testing FF102 for rollout in September and working through various issues. The latest one I've come across is the edit bookmark "button" on the right of the URL bar. It's a blank space on the URL bar, and when hovered over is a highlighted blank space. After clicking it twice it displays the Edit book mark menu.

How can I remove it completely? I've look at about:config and nothing stands out as obvious to me controlling this and I can't find a setting for it.

The image below shows the highlighted blank icon space.

This code in userChrome.css worked in FF91 but only hides the icon in FF102.

#star-button { display:none !important; }

Thanks

I've some search engines which was configured a lot of years ago (or maybe was imported from another browser many years ago). They are working in address bar (e.g. I can enter there "cve something", press Enter and get redirected to https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=something), but not listed neither in about:preferences#search nor in my profile's search.json.mozlz4 (I've unpacked and checked it - it contents does match about:preferences#search). I've tried to grep for "cvekey.cgi" in my profile folder but get no results (I suppose these "hidden" search engines are stored in some sqlite file).

I'd like to have these hidden search engines listed in about:preferences#search. I can even manually re-add them, but how can I find complete list of all configured search engines?

After update of Firefox version 103.0.1 the symbols are too big and the size cannot be reduced (to small size). So too few symbols fit into a symbol line. How can this be fixed?

I woke up this morning and my tab bar on Firefox was out of control. I figured out how to shrink the tabs in about:config. However, there is a huge space at the end of the tabs that is completely unnecessary. I've been googling all morning. I tried to find compact mode--but "density" is gone, even when I go back into about:config and enable it. The only other help I found was to change the CSS code and unfortunately, that is outside my wheelhouse.

Is there ANY way I can get my old tab bar back so that the tabs fill the top of the screen as opposed to having a huge empty space at the end?

Firefox using Windows 11 the Top Menu bar takes up to much real estate. But running same Browser on Windows 10 it works fine. How can I reduce the top Menu Bar so I can see more of Web page as far to big on Windows 11? Any ideas help appreciated. Does anyone know of a cure.? Check the attached image or Images for proof. Even some web pages its far to wide to fit screen.

Firefox has suddenly stopped sizing shipping labels when downloading them from Amazon and ebay. They print way too large. Changing the printer setting, size, etc does not help. It seems as though Firefox is converting them somehow. I have tried clearing the printer settings in Firefox also.

Everytime Firefox wants me to add something as search engine. For example I open YouTube and in the address bar it says ADD YOUTUBE. I cannot share screenshot because it just says uploading and not uploading anything from all my devices.

I have Firefox 103.0.2 and have enabled the use of style sheets in about:config. I have a CSS style sheet userChrome.css that is giving me color at the top heading and in the tabs, except for the active tab (is white)

I'll list the CSS and see if you can give me some guidance in what i need to do to put some roundness in the top corners of the tabs. the UserChrome.css file .titlebar-color{ color: AccentColorText; background-color: AccentColor; } .tab-background{ border-radius: 5px 5px !important; margin-bottom: 0px !important; } .tabbrowser-tab:not([selected=true]):not([multiselected=true]) .tab-background{ background-color: color-mix(in srgb, currentColor 5%, transparent); } menupopup > menu, menupopup > menuitem{ padding-block: 2px !important; min-height: 0px !important; }

root{

--arrowpanel-menuitem-padding: 2px !important; }

The whole top is solid color (same as Windows color, which is ok by me. However, it would also be nice if there were a dividing line or separation between the menu on top and the "tabs" below. Any ideas would be great! Thanks!! Vern

Hello,

I just upgraded to Firefox 98.0.1. And there doesn't seem to be an option to add Pocket suggestions to the homepage, as there used to be.

You can add Pocket articles that you've saved, but not suggestions from Pocket.

It used to be under settings - home - recommended by Pocket.

Has this been removed from the options?

Thanks, Taylor

I have Firefox 101. It is set to open previous session tabs but it does not. Further I am not able to retrieve the ones I used to have available when I open Firefox. I have not cleared the history.

In Settings, I have configured "When using the address bar, suggest..." to use my Bookmarks, and nothing else.

Let's say I have a bookmark for the URL: https://www.mozilla.org/en-GB/firefox/products/

If I start typing "moz", that bookmark appears in the suggestions, but the autocomplete also offers me the domain's "home" URL, https://www.mozilla.org.

I don't have that "home" URL bookmarked, so I don't want it to be suggested to me - as I told Firefox when I set "Bookmarks" as the only source of suggestions. Often when trying to navigate quickly to a bookmarked page, I assume that autocomplete will be giving me my bookmarked page, and end up accidentally going to the "home URL" instead.

So is there a setting that lets me keep my bookmark suggestions, but disable this "autocomplete with home URL" behaviour?

This isn't specific to mozilla.org: that URL was just an example.
