Firefox Community Forum

Today when I launched the browser, a sidebar appeared. No matter what I tried, I can't remove it, it really gets in the way, I searched for information all over the Internet, but I still couldn't find any information. How can I remove the sidebar?

Why Firefox is unable to bring customising options for homepage and toolbar for mobile users in all these years despite other browsers upping their game with user feedbacks and newer browsers bringing exactly what the users want?

Big phones, too many bookmarks, can't remove or hide home button icon on URL bar, no download manager, no options to add home shortcuts or speed dials on Firefox homepage no navigation buttons at bottom, no DNS, is this Firefox in 2024 and 2025?

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!

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!

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 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?

FF ver 140. just loaded and now all my sidebar bookmark fonts are black on black. How do I change the sidebar bookmark font back to white? When I disabled all Themes the white color came back, but enabling any theme and they the font turns black again.

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

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?

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?

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.

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.

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

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.

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.

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;}

}

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

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.
