Hi everyone,

I'm on 140.0.2 / Win10

My current about:config:

browser.urlbar.trimHttps false browser.urlbar.trimURLs true browser.urlbar.untrimOnUserInteraction.featureGate false

I noticed the new https trimming, but when I double-click (e.g. to select a word in the URL) to copy or change a part, the https pops back, shifting where my cursor is relative to where it was, which is annoying for having to reposition the cursor.

Disabling `browser.urlbar.trimURLs` should make sense to revert to no-trimming, but it didn't work.

`browser.urlbar.untrimOnUserInteraction.featureGate` being false already shouldn't have caused the issue I described.

Many thanks in advance!

I have the box ticked in Settings for previous tabs to be installed on Startup but it isn't happening although it used to. I was trying to get rid of caches (what are they?) and must have done something.

Firefox 139.0.1 (64-bit) on Windows 11

I occasionally increase the zoom level of websites (usually forums) with Ctrl+mouse wheel if the default text size is too small. However, if I forget to set them back to 100% (Ctrl+0) before closing the tab, the next time I open that URL, it's at the former adjusted zoom level -- not 100%. Really annoying.

How do I force Firefox to open all URLs at 100% regardless of the last custom zoom level? I have default zoom already set to 100% in Settings and Zoom Text Only is not enabled.

Thanks.

I have some code in my .css file that had restored colored folders, a la pre version 89 AFAIR, for the folders on the bookmarks toolbar and in the bookmarks menus off the toolbar. It was working in V138.

I just upgraded to V139 and it's no longer working. I have the plain black/white wireframes back for the toolbar folders on the bookmarks menus.

The code I was using is below. I didn't write it and I confess that I only marginally understand it.

Can someone help me to regaining the colored folders? The white ones are a serious visual impairment for my brain. I need them to be more distinct from the menus themselves.

How to disable the Enterprise Roots preference-have tried everything I can find on this issue. In summary, deleting certificate via reg edit but this does not work, have to delete certificate every time I re start windows 11 desk top pc.

Any other advice? Thanks

I recently updated my MacBook Pro to the latest MacOS (Sequoia). Though I didn't notice it immediately, today when I opened Firefox, all text is displayed in a foreign character set. It is pervasive - I've tried to use several tutorials to reset the language and all settings to default, but so far nothing has worked. I've uninstalled Firefox using AppCleaner (which gets any leftover files in OS folders, as well as the app itself), but a clean install results in the same issue. I've disabled all add-ons and reset all settings to default as near as I can tell. The only time the browser displays properly is when it's in Safe Mode. I'm not sure if this is related to the OS update, but I can't seem to identify any other recent change that could have the potential to cause this problem. Any suggestions would be greatly appreciated.

Currently, and for some reason there seems to have been a change that's occurred because my browser seems to think I'm out of the country (USA) as my searches return "We don't ship out of the country." How do I tell my browsers that I'm in the USA?

Hello Firefox friends o/

Anyone knows how do I make https://yandex.com my default search engine? (in the top bar of the browser). I have attached a screenshot of my settings page. Please have a look at the suspicious lack of an "Add" button 🤔. Despite my efforts, the drop-down menu will not show the available options in the screenshot, you will have to take my word for it, the only available options in that menu are: Google, Bing, DuckDuckGo, eBay and Wikipedia (en).

P.S. The settings page in Firefox must change really often, as I seen so many people suggesting many outdated methods online.

I have encountered an issue very similar to the one described here: https://support.mozilla.org/mk/questions/1407928

Firefox (version 130.0.1 (64-bit)) is not playing audio through headphones. Have tried a number of sites - e.g. YouTube, internet radio stations, news sites.

However, unlike in the above-mentioned support article, the Windows App Volume and Device Preferences settings are set to default.

I have since also tried restarting my PC (Windows 10 ; Version 22H2 (OS Build 19045.4651) and resetting the App Volume and Device Preferences to the Microsoft default settings (see Image attached).

I also tested and audio plays fine through Chrome browser, VLC media player, Teams and Edge.

Would love to find a solution! Thanks D

I have run across threads with similar questions in both mozilla support and reddit, but as they are old and archived I cannot add additional info or request clarification, so here is (yet another) new one- I understand you can go into manage data in settings to delete what you want, however in mine it only shows a handful of most recent (opened today or currently open) since my settings clears history and deletes cookies upon exiting ff.

Cookies and Site Data section shows only 40.7mb of data is stored and in Manage Data only shows 8 sites... Clear Data area, with only these two boxes selected (attached) and 'everything' (time) still only around 50mb. My storage/default folder has 1005 folders and the data is over 1.5gb; I would like to manually delete all of this and as others have tried to ask, am wondering if this is ok to manually select them and delete in windows, or using windows %appdata%(?) and if so, will the sync feature (if I just clicked 'sync now') still retain all my bookmarks when I relaunch ff? Not concerned about any browsing/form history or passwords, only bookmarks.

Helllllllllllp! Just had firefox install an update & now all my saved bookmarks, login passwords & previous home page have all gone. Have reset Home page, checked that Profile is correct & the bookmark folder is empty. Where have they all gone. Yes I have restarted my computer but made no difference.

I know that addons have no power on special pages. I understand the security concerns and I agree. I would still like to at least open `about:about` from an addon, like e.g., vimium or just from a bookmark. Is that possible? And if so, how?

I know I can hide the sidebar by clicking the button on the toolbar. But I'm used to opening my bookmarks and history with ctrl+b and ctrl+h, and being able to close them the same way. This still works to close the actual bookmarks/history, but the sidebar doesn't return to being hidden (despite being hidden before I opened them), it hangs around taking up space on the left of my screen. Even after I removed everything so it's just a useless blank rectangle with "customise sidebar" at the bottom, it defaults to staying open unless I click the button. It's really annoying. Is there any way to make it hide itself again automatically once I'm done using it?

Hi All,

I need open local exists files

file:///.../index_details.rst or file:///.../index_details.txt in my default system editor.

This has worked pretty well last in version 127. (https://ftp.mozilla.org/pub/firefox/releases/127.0/linux-x86_64/en-US/)

But after v127 Firefox always opens files directly (see screen). I can't find any settings to change this behavior. Something has been changed.

I keep back the firefox upgrade so long it was posible for me but 127 is now old and i use the last version 133.0-1.

I'm using Linux (Debian).

Thanks

How to shrink this vertical space? (see attached image)

Ever since 131.0.0 my shortcut icons got all messed up so I am trying to restore the original look. I've already removed the giant Firefox logo and made my icons larger. Now I need to condense them so I don't have to scroll to see them all.

Here's what I have so far in my userContent.css:

/* Minimize the size of the logo and wordmark on the Home/New Tab pages */ @-moz-document url(about:newtab), url(about:home) {

 .logo {
   background-size: 0px !important;
   height: 0px !important;
   width: 0px !important;
 }
 .wordmark {
   background-size: 0px !important;
   height: 0px !important;
   width: 0px !important;
   margin-inline-start: 0px !important;
 }

 /* Expand the shortcut icon images to max size on the Home/New Tab pages */
 .top-site-outer .tile .icon-wrapper {height:100% !important; width:100% !important;}

}

Well looks like they did it to us again. My tabs are back on top again and need to put them below where I am a lot of other users like our tabs!

Update: Codes working fine now for 133.0

Firefox Nightly 135.0a1 - Debian APT repository

I searched around DDG for awhile and didn't seem to find others with this issue. I have Firefox-esr installed on another device and the option is still enabled over there. Is there a way I can gain that back on this install? I use it for every link I copy. Thanks

Out of nowhere I got the sidebar today. An absolutely useless feature that I surely did not ask for. And there is no way of closing or removing it. Please provide a guide, to removing or hiding it PERMANENTLY!
