Hi I try to move from Google Chrome to Firefox but I fail on a simple but important setting. How can I set the home page to a specific URL. If I go to settings -> Homepage I do not find the field where I can set my homepage. Thanks, Rupert.

Currently using Firefox Nightly version 111.0a1 for Android now when trying to open a link in another app it always shows a popup to confirm.

This was not present in previous releases and I don't know if there is a way to prevent this popup as it makes it uncomfortable. Is there an option I may be missing to disable this feature? If not, could an option like this be introduced?

Thanks and regards

Kubuntu 22.04 Thunderbird 102.7.1 (64-bit)

I simply cannot change the default browser from Chrome to Firefox.

• Firefox is my default browser.
• I've set network.protocol-handler.warn-external.http and network.protocol-handler.warn-external.https to true.
• I've edited the attachment entries for https and http to "always ask"
• I've delete the attachment entries for https and http

No success. Thunberbird always reverts the setting to Chrome.

This should not be so complicated :( Why not a simple setting "Default browers" and pick one from there?

I really often need to copy/paste from a terminal opened in my browser. Because the shortcut for copying in a terminal is always Ctrl+Shift+C, it's a mess to have instead Firefox opening Inspector from devtools.

How can I disable this shortcut ?

I've tried to update some about:config settings but it doesn't seem to be helpful and old working correctives add-ons are not supported anymore.

Hello,

I've changed the background color on the private tabs/windows with this CSS:

@-moz-document url(about:privatebrowsing){
 html.private{
  background-color: #2B2A33 !important;
  --in-content-page-color: gray !important;
}

I would like to make the "background-color" to be the same as the window background without hardcoding it, so it always match the theme, ie:

 background-color: <window.background> !important;

I would like to do the same with the background color of the search box in the private mode window, but I can't find the id.

Regards.

Extensions no longer shows on Customize Toolbar tab on the latest version 111.0. I had Dark Reader and SoundFixer on the toolbar before and I can no longer add them back.

I was totally blindsided by the changes imposed by the switch to this feature. Having now read up on it I can understand the need for it, but IMHO the implementation is... not optimal. Why do we have to have two "overflow" icons? Why could the two functions (traditional overflow list and new Extensions Management) not be maintained under a single button/function as before? (I don't care which symbol would be used, but splitting up the access to these functions? Come on!) AND why can we no longer order the items on the new overflow menu the way we want? --at least, I haven't found a way to move them around. Further, when extensions say that they "Can't read and change data on this site", does that mean that the extension is broken, nonfunctional, locked out, etc., or are we required to do something to restore it to functionality? -And if so, do we have to do this for every extension, on every site? Let me just say, not a huge fan at this point. Ugh.

Hello dear Mozilla (or should I say Thunderbird) crew and community,

Some months ago, in December 2022 I think, under Windows 10, my Firefox webbrowser got started whenever I started Thunderbird, showing a request for donation screen. Having enjoyed the benefits of Thunderbird for a long time, I thought it was reasonable to donate. I hoped the screen would disappear after this, but it didn't. I have searched for solutions to get rid of it, because it slows down TB whenever I want to look into my emails. But sofar, without success. The only things I DID find were that I can get rid of the screen under Linux (as a normal user). Under Windows I can start TB 'as Administrator' and then remove the URL (see below) from the settings. But as I recall it, it reappeared after a couple of restarts of TB even in this case. And starting TB as Administrator gives me no access to my emails which are stored under my user account. Removing the URL, by the way, can not be done through the normal settings screens. I had to go to the "hamburger" menu icon and then select Settings, scroll all the way down and then click on the Configuration Editor button. There I found these three related parameters and their values:

app.donation.eoy.url = https//www.thunderbird.net/thunderbird/102.0/eoy/ app.donation.version = 1 app.donation.eoy.version.viewed = 1

My questions:

1) Why can't I remove the URL for the "end-of-year" donation screen as a normal Windows user?

  Every time I delete it, it's back the next time I start TB.
 (for God's sake, it's almost April by now and I DID donate at year's end ;-)

2) The file 'prefs.js' in my user mail profile/directory seems to hold part of my settings, but it states "DO NOT EDIT THIS FILE". Could I define a 'user.js' file to actually circumvent my inability to remove the URL through the Configuration Editor? 3) Or even better: what IS the right way to remove the donation screen in my situation; or put differently: is this an error (f.e. with user rights) in the Windows version of TB not present in the Linux version?

Thank you in advance for your help or suggestions,

When I open "Extensions" (about:addons) by clicking the Extensions icon, I want it to start on my own extensions, not Recommendations. How can I make "Extensions" open to the actual Extensions tab? Or can I remove the "Recommendations" tab entirely?

I already saw [to remove 'Recommendations' tab in about:addons]. But about:config

 extensions.htmlaboutaddons.recommendations.enabled = false

only removes recommendations from the Extensions tab. And adding

 extensions.getAddons.showPane = false

does not work, the Recommendations tab is still there.

Made a mistake by changing user_pref("layout.css.devPixelsPerPx" from I think - 0.5 to +0.5 as incoming emails font was miniscule, but made nor difference... so thought it may be a font size, so changed to 12.... Now ginormous and unreadable. Searched through pages here for an answer and got to the prefs.js folder to find this file but it is not there.... I searched with notepad edit search for "layout" but no luck. Any ideas anyone? I tried adding the line user_pref("layout.css.devPixelsPerPx", "1.5"); whilst TB was closed and then opened TB but had made no difference.. :-( Any ideas anyone? TIA Graham

I've tried following both methods for dissabling the mute button on tabs, it's a slight annoyance, since it's easy to accidentally mute a tab when it's pinned.

Specifically, the first method I've tried changing the setting in about:config called "browser.tabs.showAudioPlayingIcon" from true to false, which was from 7 years ago it seems, which had no effect.

The second method was by making a new rule in a "userChrome.css" file in a new folder called "chrome" with that exact naming, case sensitive. The code in that file is as follows:

/* Hide the mute/unmute button */
.tab-icon-overlay:not([pinned], [sharing], [crashed]):is([soundplaying], [muted]) {
    display: none !important;
}
/* Keep site icon visible on hover */
.tabbrowser-tab:hover .tab-icon-stack:not([pinned], [sharing], [crashed]):is([soundplaying], [muted]) > :not(.tab-icon-overlay), 
     /* for site icon with Compact density */
:root[uidensity="compact"] .tab-icon-stack:not([pinned], [sharing], [crashed]):is([soundplaying], [muted]) > :not(.tab-icon-overlay) {
    opacity: 1 !important; /* overrides full transparency with full opacity */
}

If there's an updated version of the code that's meant to have that effect in modern firefox, then please let me know, or if there's some other new way of removing the mute button on tabs. Thanks.

Hi there,

I'm trying to add multi-containers add on to a new Firefox install, it installs, but the icon doesnt show up. It's not hidden in the customise toolbar menu either. Have tried removing/re-adding, but it doesnt come up. It is possible to get to it by clicking the extensions icon, then clicking multi-container, but this isnt very user friendly. Is there a way to resolve this?

Thanks!

Firefox 112.0 running on Windows 10 64-bit laptop with a small (pixel geometry) display screen has unnecessarily large padding (white space) around each bookmark as I navigate bookmarks on the bookmark bar.

I believe this was a change instituted around version 89 (in a nutshell, I could see more - twice as many? - bookmarks listed within a bookmark folder with version 88/before. The vertical whitespace between bookmarks within a folder is excessive and makes it much more necessary to scroll within a (long) list of bookmarks in a folder when looking for one.

There was a procedure posted in the discussion below on how to set and enable "compact density".

Bookmark Padding in New Firefox Versions 2 https://support.mozilla.org/en-US/questions/1369996

The procedure below was attempted - browser.compactmode.show enabled, browser restarted, however, I cannot fin "Customize Toolbar" and "compact".

"go to - about:config search - "browser.compactmode.show" - change to TRUE , then close that window go to - Customize Toolbar at the bottom of that page, there a box called Density. Click that, you'll see "compact (not supported)" Apparently, it IS supported because I chose that. (it looked like it ignored my choice) After I closed Customize Toolbar, the bookmarks were compact spaced again. Exactly how I need them."

Is this fixable/solvable?

I'm using the 64-bit version of thunderbird and I'm unable to increase the font size of the incoming messages in my inbox. I went to settings, general, Language and Appearance and under advanced changed fonts to 24, 20 and 20 while checking off the font control boxes. None of these changes the size of the text in the body of the text. Any help would be greatly appreciated.

When I type about.config in the address bar, I just see search results for it, instead of going to the config page. I tried enabling a separate search bar in settings, and also turned off all suggestions, but that did not help. I still see the spyglass search icon on the address bar. How do I get past it?

I am looking at houses several times a day as they come in on emails. I was hoping there was an alteration in the settings that when clicking on a link it opens that link in the browser, but I don't lose focus from Thunderbird. There could be a hundred emails with house details, and I need to go through them methodically. What would be great to do, is click on the link if interested in the house details and then delete the email. Leaving me opening the new email with more house details, whilst the browser stays in the background. When I have completed the emails, I look on my browser at the ones I found interesting. Is there such a setting or addon for this? I hope I have put this succinctly? Thanks for reading, hope there is an answer.

Firefox 114 introduced hidden support for nvidia video super resolution. In about:config you can enable preference gfx.webrender.super-resolution.nvidia to make it work. However I see 0 difference on all videos on all pages. I have everything in nvidia control panel set correctly (VSR enabled and set to 4/4 quality).

Tried to find more info online and someone on reddit complained that it worked before but it stopped working with latest firefox beta (probably before final 114 release): https://www.reddit.com/r/firefox/comments/13duluz/nvidia_video_super_resolution_comes_to_firefox/

I tried using logic too - if this pref is related to webrenderer in its name maybe it is not working because I am not using webrenderer? However I checked about:support and in section graphics->composition I have "webrenderer" so it seems I am using it, but its VSR feature is not working at all.

I have no usable Menu options at the top of the Thunderbird email screen. I hit a wrong key yesterday and things such as Write, Reply, Print, Send, Delete, Junk, etc. have disappeared. I read some possible things to help but I do not have III on the upper right of my screen and pressing Alt when opening Thunderbird also does not work. HELP!
