I-Firefox Community Forum

I have tried every support advice I can find and no matter what I do passwords are not restoring. Here is what I have done: Opened about:profiles Opened profile folder Exit firefox transfer key4.db and signons.jstor files from backup to the new folder

Nothing happens.

I have tried creating new folders and following those steps. I have tried everything.

Hi. I have followed the instructions on the Mozilla site above however this does not work. The Enterprise Roots keep reloading after a while.

Any idea how to stop this happening?

I have read many articles on this but nothing works. The E Roots will in initially not reload but eventually after a day or three its back.

Many thanks

Why is there in about:config no reference to documentation of the displayed settings?

e.g. browser.chrome.toolbar_tips.hide_on_keydown

What is it? What is the meaning of the values? What is the default value? Why do we have to guess?

It is probably documented somewhere (I hope). Why is there no reference to it in about:config?

Is there a way to make the URL high lighting of the domain more obvious? I find that most people can barely see the highlighting and I'd like to make it obvious (bolder and red, or highlighted in yellow, for instance.)

Can this be done via userchrome.css?

Thanks,

Thane

Good day everyone,

I have been breaking my head over this for about a week. After the last update that was installed, now my tab width is smaller than the minimum width I have set them to. However, this only happens with active tabs from pages that have an embedded video. At first I thought this was just a thing with YouTube, but it seems it also happens with other video sites. I guess it may be related to whenever the playback button displays in the tab title and it detects there is video content.

I would like to know how to fix this behavior so that my tabs are no longer shortened beyond the minimum width setting.

Thank you in advance.

Hello Since few weeks (maybe on firefox 132 already, but surely on firefox 133) I observe issue with my firefox UI. While grabbing and holding tab (to change its position, move it on bar), whole tab bar gets thinner which realigns my whole UI. Issue is probably caused by my custom userchrome.css but I need it in current or similar form. Maybe there is some css specialist who can help me remove unnecessary parts of code?

My css is as follows:

.tab-background{ border-radius: 0px 0px !important; margin-bottom: 0px !important; } .tabbrowser-tab:not([selected=true]):not([multiselected=true]) .tab-background{ background-color: color-mix(in srgb, currentColor 4%, transparent); } menupopup > menu, menupopup > menuitem{ padding-block: 3px !important; min-height: 0px !important; }

root{

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

This button that looks like a jig saw bit will not budge.

Can I delete this in about:config by deleting the 'unified extention button' and can I delete the 'HKLM/SOFTWARE/Wow6432Node/Mozilla/Firefox/Extensions' in the registry?

Firefox these days is getting a burden with more info and such like being collected behind out backs, it's about to be ditched on all my computers, the last few episodes make me want out.

Transferring bookmarks & backups for passwords is easy and I'm not worried about that. But the about:config settings that I have customized and accreted over years so that nothing beeps, spins, auto-plays, loops, or throbs a tab, are not so straightforward. I'd like to review what files I can save how to make sure I do not lose these, which are the most important things to me about my Firefox installs--keeping the web safe for quiet, nondistracting searches and reading.

Changing Default Behavior (CSS)

When I'm reading on a computer screen, I hatehatehatedespisehatehatehate "widow and orphan" control. This is especially annoying when reading a long narrative passage that reflows so that a break (often a blank paragraph) falls at the bottom or top of a column/page. There are two relevant CSS properties, each taking a nonzero positive integer as an argument:

    widows: [number of lines]
    orphans: [number of lines]

It appears that Firefox has (like most browsers) established a "default" value of 2 in each of these parameters, which seldom appear in site-specific stylesheets. Do Not Want.

Is there a way to change this default behavior to the equivalent of:

    body {
         widows: 1;
         orphans: 1;}

without either (a) breaking anything or (b) having to redo whatever change every time there's a Firefox update?

new Date(1743623960000).toLocaleString(['en-ES'])

outputs "4/2/2025, 7:59:20 PM" in normal firefox and "2/4/2025, 7:59:20 PM" in Firefox Developer. Test on MacOS and Ubuntu.

Hi. There is a new feature of Firefox that bothers me. It is when I drag tabs around the top, they try to group when I don't want them to. So I go to about:config and find the "browser.tabs.groups.enabled" key and set it to false. But when I restart Firefox, the change reverts. How do I fix this so the change stays?

I've already tried going to Menu->Help->More troubleshooting information->Profile Folder->Open folder, but there is no "user.js" file there. Do I have to do a Firefox reset to fix this? I hope not...

Note that I'm pretty sure that other settings that I change do not revert when I restart Firefox. Right now, it seems to be just this one about:config setting, unless the new version of Firefox reverts all manually changed about:config settings upon restart.

Thanx in advance for any help.

Steps to reproduce- (1) Enable 'accessibility.blockautorefresh' in 'about:config' (This is said to ask for permission before redirecting) (2) Go here (3) End up here without permission

Extensions I'm using- Privacy Badger, uBlock origin, clearURLs and Show/hide passwords

Another question, does enabling this setting also stop internal redirection?

I need to block domain in my Firefox. Lets say example.com. Better if via about:config

Extentions is not a solution (sorry, I cannot comment this for privacy reasons)

Hi all,

I’ve been using Firefox for a while now, but coming from Chrome, I’m finding some aspects of Firefox’s cache management and tab behavior a bit inconvenient, and I wanted to share my thoughts.

The issue:

When I restart Firefox (version 133.0.3-1), it loads webpages from the disk cache, which is fine because I’ve set browser.cache.disk.enable to true and browser.cache.check_doc_frequency to 2, it will always make a request to the server on restarting Firefox with the default value of 3. However, the problem arises when I open new tabs — they also load from the disk cache instead of requesting fresh content from the server.

What I’m looking for:

   A way to have Firefox:

Load webpages from the disk cache when restarting the browser (which I want, and I have set browser.cache.disk.enable to true for this). But always make fresh requests from the server when opening new tabs, no matter what the cache settings are.

In Chrome, this behavior is more intuitive — it loads from the cache after restart but always fetches from the server for new tabs, which I find to be much more reasonable.

I understand that about:config provides settings like browser.sessionstore.restore_on_demand, but adjusting this option makes Firefox fetch content from the server for all tabs, including those opened after a restart. This doesn’t seem like a perfect solution because it takes away the ability to use the disk cache after restarting the browser.

I would really appreciate it if Firefox could offer more granular control over this behavior, so users could get the benefits of both caching and real-time requests based on the type of tab (restart vs. new tab).

Thanks for your attention, and I hope to see some improvements in future updates!

Hello!

I would like to dump Chrome and return to using Firefox. I just would like to know if it's possible somehow to remove about:mozilla page from within a browser (it's important for me). If anyone knows of a way to do it - please let me know.

Thank you!

Recently (around Fx 134) css code for chrome files stopped working. The code I use is set out below. It previously changed the background colour to tan ( #dbc3a3 ), the text colour to dark blue ( #000080 ) and the font size to 17 px. The code found at the following location also no longer works for chrome files : https://gist.github.com/MrOtherGuy/c592f6443dd228022966cbe5715ad5c9

@-moz-document url-prefix("about:"), url-prefix("chrome://"), url-prefix("resource://"){

 :root {
     --in-content-page-color: #000080 !important;
     --in-content-text-color: #000080 !important;
     --in-content-page-background: #dbc3a3 !important;
     --in-content-box-background: #e2cfb6 !important;
     --in-content-deemphasized-text: var(--in-content-text-color) !important;

}

I asked this question two years ago and the chosen solution no longer works for newer versions of Firefox. (135 in my case) . setting editor.use_div_for_default_newlines in about:config to FALSE does not work.

I am tired of pressing SHIFT <enter> to get <　br　> . Unnessessary <　div　>s make code harder to read.

Any new setting I could use to get
for pressing the enter key?
