Firefox Support Forum

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.

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.

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.

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.)

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.

Hello, I regularly open pdf files and other documents with local readers/writers by selecting the option "open with". My big issue is that the files are yes opened with the local reader, but they are also automatically downloaded in the "Download" folder.

Before files were stored in a temporary folder, and I would like to continue like that because my "Download" folder is exploding and it's a mess!

Or, at least, there should be an option to select where to download automatically the files when I select the "open with" option. So I can chose a folder that I now is to be trashed.

Thank you!

Hi,

I use Mendeley Web Extension to pull articles and other things from Firefox directly into my Mendeley library. I will usually rapidly read through the PDF file online before deciding to add it or not. For some unknown reason, Firefox blocks the use of Mendeley on PDF file, for security reasons, and I can no longer add them to my library. Most references are only available as PDF files making the add-on completely useless. Is there a security feature that I can disable to be able to use the extension again?

Kind regards,

Mathias

I started up my computer today; I tried to open up a youtube video in picture-in-picture add-on, but it wasn't there. I restarted my computer, completely closed firefox, looked into settings for the picture-in-picture settings that are supposed to be under 'Browsing' in General but I can't find the settings for it there either. I have tried using other video sites, but nothing works.

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.

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 ?

There is no userChrome.css in my profile.

If it needs to be created, where do I create it?

Yes, I searched for help. What I found was about userChrome.css to solve specific problems, but not what to do if it doesn't exist. Is userChrome still supported?

Thank you! Mark.

Hello,

I am running Firefox v101.0.1 (64-bit) on Linux (Pop!_OS, installed as a flatpak). I am using the default system theme in dark mode, though switching to the Firefox dark theme or other themes does not change anything. When I allow the Menu Bar (File, Edit, View, etc.) to be present, the browser tabs on the next line are aligned correctly, going all of the way to the left. When I uncheck the Menu Bar, however, a gap appears to the left of the tabs. I have not seen this behavior on Firefox in other environments (Debian, RHEL, Windows), and I'm wondering if there's a way I can remove that gap. I have attached screenshots showing how the tabs are aligned with and without the Menu Bar.

Thanks so much!

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

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 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).

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.
