Currently using 101.0 (64 bit) on Windows 10.

It's quite annoying to try to type a capital F using Shift F but end up with developer mode.

I tried in privacy mode and this still occcurs, so I think it's not something my add-ons do.

Is there any way to disable this feature?

Hello. I just closed by accident my main window so I restored it, but it apparently lost all the container data and restored all non-pinned tabs to the default container.

Is it normal, is it a bug or is it a yet-to-be feature?

It feels like a bug because pinned tabs (which were not present/open in the secondary window that stayed open when I accidentally closed the main one) where duly opened in their respective containers.

I am trying to set youtube to always open in Youtube container , when i right click on the logo or name of the container it doesn't do anything , at previous version was fine , is there any issue with current version ? is there another way to enable youtube to open always in it's own container ?

I have Firefox 101. It is set to open previous session tabs but it does not. Further I am not able to retrieve the ones I used to have available when I open Firefox. I have not cleared the history.

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.

My bookmarks toolbar is empty. When looking through the bookmarks menu, it shows that none of my bookmarks have been removed, and they are all still listed as being present in the Bookmarks toolbar, but they are not displayed in such. To be clear, bookmarks toolbar is enabled, and I have already verified its positioning in the customize toolbar pane. There is a strip of empty space where they used to be, but they are simply missing now. How do I fix whatever issue caused the toolbar to cease displaying my bookmarks?

Firefox says I need a video codec to play a video (that is aparently somewhere on the page). It does NOT tell me what video, what video format, or what codec I need. How do I find out what codec I need?

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.

For some whatever-reasons (TLDR; I need to see the whole domain (including subdomains) clearly, unlike the default of only highlighting the TLD&second-level domains[1]) I want to disable the color-distinction which highlights TLD and second level domains.[2] Is there config to do so? If not where should I propose one?

Thanks.

[1]: for example ko.wikipedia.org and en.wikipedia.org will have wikipedia.org highlighted, and that's what I can't accept because ko.wikipedia.org (Korean) and en.wikipedia.org (English) is completely different site. (Some might say you can distinguish by language, but there are some English sites which shares the same domain on wikimedia.org, so you get the point here.) [2]: From the screenshot you can see only `wikipedia.org` is highlighted. I want to make it highlight all of en.wikipedia.org. (If I need to highlight everything including the site path below the TLD, I can accept that.)

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).

Dear Sir or Madam,

I'm running 101.0.1 and spell check no longer works on any mail app like Gmail, Outlook, Yahoo, BT Mail. If I use Chrome or Edge then spell check works correctly. This is despite my Firefox Settings being as below.....

Language Choose the languages used to display menus, messages, and notifications from Firefox. ENGLISH GB Set Alternatives… ENGLISH GB Choose your preferred language for displaying pages. Choose… ENGLISH (United Kingdom) (en-gb) Check your spelling as you type = Tick (Yes)

Could you please advise a fix?

Kind regards,

Neil.

P.S. If I use Chrome or Edge then spell check works correctly.

I used a siteblocker and i tried blocking about:addons, wouldn't allow it so someone tell me how. im literally trying to prevent myself from removing extension i literally jumped from one browser to another just to make this shit possible please.

I'm trying to load a temporary add-on on my browser, but when I click the button "Load temporary add-on", nothing show up.

I tried to look for errors in the console or debugging tool, but nothing. With snap, I removed with the purge option my Firefox and install it again, but the issue still appears.

Some technical details: Ubuntu 22.04 LTS Firefox version 101.0.1 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

For ‘few a few weeks now the option to choose where to save files has failed, even with the latest 101.0.1 (64-bit) on windows 11 Home. Any ideas?

This evening I changed the default location to my data area, so at least it will hopefully defaulting to ms 'downloads' folder.

OS Name Microsoft Windows 11 Home Version 10.0.22000 Build 22000

I use an addon to mute all tabs by default. The problem is that muted tabs have the MUTED text, which shrinks the size of the tab name/title. My old eyes can't deal with that very well.

Is there any way to prevent this text from showing up globally? Thanks.

I just upgraded to Monterey on my Mac running FF 101.0.1 (64-bit). I cannot add new search engines to my list of search engines. I'm trying to add DuckDuckGo without success. I have Google, Bing and Startpage. I click on Find More Search Engines, select and add DuckDuckGo but while it appears as an extension it does not appear in the list of search engines.
