Firefox Support Forum

This isn't a question about the "Multi-Account Containers" addons, I am pretty sure that there was a section called "Container tabs" in the privacy and security settings, and I could use containers without installing an addon some days ago.

I can still access by directly viewing this address

about:preferences#containers

But I can't find it in the settings, and this feature does no longer work.

So I went to read recent release notes from Firefox 100 to 101.0.1, but I didn't find any notes to say this feature has been disabled. Could this be an unexpected result of an update?

Unable to complete backup of firefox profile because of over-length file names in storage sub-directory. Is is ok to simply delete one or more file names which are old URL's and no longer required? Clear History All doesn't clean them out. (Firefox 101.0.1 (64-bit) on WIndows 10) thanks

Using Mac OS 12.4 and Firefox 101.0.1. After launching Firefox, a second icon appears in the "recently used" apps section of the Mac OS dock (see attached screen shot). The icon stays there and goes away, and then comes back, and then goes away, etc. This continues on and on until Firefox is closed.

Why is this happening? Never acted this way before the latest updates.

Hi guys. So, I have Avira free antivirus. Can I still install for example Norton web security addon for Firefox? Will there be any problems between my installed antivirus and the Norton addon? Sorry if this is a noob question, but there you go :) Any help would be appriciated. Thanks in advance for any reply.

I want to select multiple Tabs from a bookmark folder to open in the background.

On Chrome this used to be quite easy: Just open the Dropdown, click whichever tabs you wanted to open with the Mousewheel and done.

On Firefox you need to enable new tabs to open in Background first. I managed to find the setting for that with google after a while. You need to go to advanced settings by typing about:config into your url bar.

Then you search for browser.tabs.loadBookmarksInBackground and click "enable".

But this didn't fix the other issue I had, that the dropdown menu always closes as soon as I click anything.

Is there a way so it stays open until I'm done selecting the pages I want?

Hi, I have this problem that is driving me crazy, I know it is not an issue with firefox but I really appreciate any help.

The problem is that there is a grey html code in inspector when rendering the html page, the grey code is not exist in my original file but that grey code I had already deleted it after using it a while, but it is still appears as grey code in inspector and this made me some issues in jquery.

So how can i get rid of it ?

Thanks

In the bookmark-bar in my Firefox-installation contains the soft-button for the function "Import bookmarks". I do not need this function always showed in the bookmark-bar. How can i remove it ?

Hello Please explain to me how to transfer tabs from desktop to Android phone because there is no option on my desktop browser settings and no matter how much I sync, the desktop tabs will not be transferred to the phone again. please guide me

I am trying to download a spreadsheet file which has a .xlsx extension. Firefox insists on downloading the file (my default action) but I want to be given the option to open in my spreadsheet program (Libreoffice).

Looking in Settings and scrolling down to Files and Applications -> Applications, there are other spreadsheet formats present but not one for .xlsx. How do I add the "Always Ask" option for .xlsx files?

Libreoffice is the default system application for opening these files.

Hello, I experience a XUL Runner error message after attempting to update Firefox and in following the guidance to rectify the error deleted the Firefox folder including the bookmarks. Is there anyway of recovering the bookmarks (maybe with a third party program) or are they lost forever? Thank you.

Firefox wasn't working well on a seldom-used laptop, and the update to 100.0.1 didn't go quite right, so I deleted the old version and (using the odious Edge) tried downloading a fresh copy of the software.

But then I get a message from "7-ZIP" that reads "Can not create temp folder archive"

I'm stuck. Advice?

I am reinstalling Windows\Firefox, and would like to hide\remove Bookmarks Toolbar & Other Bookmarks, as shown on the images. The Delete Folder option is greyed out for both, and Other Bookmarks is empty.

Both were hidden\removed in my original installation, but I can't remember how I did that. I've seen posts mentioning e.g. browser.toolbars.bookmarks.2h2020 (it doesn't exist) in About:config, right-clicking on the Other Bookmarks and uncheck it (it doesn't exist).

I'm using Firefox 101.0.1 (64 bit).

Instacart webpage suddenly will not display/open on Firefox but can display fine on Chrome. Instacart App on mobile phone works fine, just won't open in Firefox. Any suggestions other than using Chrome? Firefox version 101.0.1 Windows 10. Was working fine until latest update installed this morning.

Title says it all pretty much. I have text cursor indicator turned completely off on windows, so that's why I'm wondering why Firefox does it when I never enabled something like it. I have the ctrl+pgup and ctrl+pgdown button combos binded to my extra mouse buttons, and I use them very frequently, so this starts to become really annoying really quickly. Especially if I've somehow accidentally 'selected' something on youtube or such, and then it displays a big blue blob out of nowhere. I don't know if this is a purposeful feature or what, but I would appreciate it if somebody could tell me how to disable it, it's extremely irritating.

For the past few days I get the request to enter captcha characters every time I try to access the Amazon website using Firefox on my Win10 PC. It works fine on my Firefox for android on my phone and also works fine using the Edge browser on this PC.

I've tried resetting Firefox. I've tried troubleshooting mode. I've tried turning off enhanced tracking. What else could cause Amazon.com to feel the need to verify that I am not a robot ?
