About two months ago, after various Windows and Firefox updates, I can no longer make Firefox the default browser. In Windows Default Apps the only option for FF is to make it the default program for Adobe Acrobat Document. Choosing Make FF Default through the browser does not work either. Additionally, I’ tried numerous suggestions, using AI help offered by both FF and Chrome, without success.

The OS is not allowing me to make Firefox the default browser. Is there any way around this?

Any suggestions?

Firefox: 155.0.1 (64-bit) Windows 11 Pro Version: 25H2 OS build: 26200.9278

Thanks

In Firefox on my Android phone, when I type about:config in the address bar and press Go, it takes me to a description of that functionality, not the configuration page. I have tried DuckDuckGo, Chrome, and Bing, and they all do the same thing. How can I go to the about:config page?

My Firefox version is 152.0.5 (Build #2016171143). My phone is a Galaxy A32 5G, model SM-A326U, Android version 13, One UI version is 5.1.

I wanted to use the new VPN feature and the icon initially showed up in the top right, but it has disappeared and is not present in "customise toolbar" or privacy settings either.

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've never had sponsored shortcuts and suddenly today I've got them. I've attempted the disable the "sponsored shortcuts" on my desktop however its greyed out.

Starting state - Shortcuts selected, sponsored selected and grey Procedure: 1.) Deselect shortcuts, select shortcuts, sponsored becomes cyan 2.) Click sponsored, it becomes grey again 3.) Deselect shortcuts, select shortcuts, sponsored becomes cyan (again) 4.) Click sponsored, it appears deselected 5.) Hit refresh and it returns to starting state

I do not edit my GPO or registry, settings are not controlled by an organization, I am not confusing sponsored shortcuts with pinned search engines.

The Support forum is full with people having this problem and it seems no one at Mozilla can even b.u.t.t in with something like "we are working on it" or "here is how you can fix it yourself, also for none nerds" or anything?? Hello Mozilla, are you still alive or should we move on to a browser that does not malfunction on such an important issue as copy and paste? P.S. no answer is an answer too Mozilla, we can safely assume you are now buried on boothill, right?

Is there somebody to answer my questions please? For the first site, it is impossible to have the PDF document when clicking the button. For the second, when I click to the "buy tickets" button, it doesn't work. What's wrong with the Firefox navigator????????????? Thank you.

Les sites suivants ne fonctionnent plus sur mon navigateur Firefox. Est-ce normal? Merci.

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.

Before the recent 1-2 updates, pdfs,pictures and .torrent meta files used to get saved in temp folder which I LOVED very much. Recently these are getting save in my download folder instead of saving in the temp folder.

I changed this setting to allows ask. Still the files are getting saved in the download folder after opening.

Please assist me to resolve this issue. Thanks.

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?

I had a background image for the new tab page that has suddenly stopped working, it just displays a white screen. I clicked the 'reset to default' button next to 'Wallpapers' on the new tab page to try to fix the problem but nothing happens. No wallpapers show up under that section either where it used to be when it was working. I've restarted Firefox and the same thing happens. I have not enabled any third party CSS wallpaper.

Apart from that, everything else is working as it should. I'm sort of a computer-idiot so if anyone could please use layman's terms it would be very much appreciated!

Hi,

After the last two updates, the **Pseudo-elements** tab in the Browser Console can no longer be closed once it has been opened, and vice versa.

Please see the video below demonstrating the issue:

Thanks.

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?

6/21/26 This morning I could not open my FireFox browser, unless i created a Profile. I was forced to use the Profiles Wizard to create a Profiles; when i finished all my Bookmarks had disappeared. Which was a great shock, had lots of Bookmarks in Bookmarks Toolbar, Bookmarks Menu, & Other Bookmarks, I need to get those Bookmarks back !! >>More info: I had Hibernated my Dell 15 laptop overnight. This morning when I turned on the laptop, I got the above message that I had to create a Profile, which I did, which made all my bookmarks to DISAPPEAR !! I need them back!

I'm having some trouble with automatic translations on firefox. I don't know if It's exclusive of firefox, but some websites, mostly wikis, open a "translate" field that automatically creates a new website, wich causes the images and some other stuff on the website to break. I tried disabling the translation on about:config off, as show in some other questions, but it did not work. This is being really annoying because it keeps breaking websites unless i get to the original link.

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

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 cannot seem to find what it is called, but only web design related stuff to scrolling.

I'm looking to change the behavior of scrolling bar, that lets me click a point and the page stops at that point, whereas right now, it keeps scrolling to the end/top of the page (based on the direction relative to the starting point). I find the behavior pretty annoying and something that used to be done by the buttons on either end point.

Is this a relic of the past or can i opt-in to it through the config
