https://support.mozilla.org/en-US/kb/containers seems to suggests that it's possible to hide all tabs in certain containers, but does not explain how to do that.

"Hide and Show: Assume you use your browser for both Work and Personal tasks. When you come home at the end of the day, you don’t want to be thinking about “Work” anymore, but your browser is full of Work tabs. You can “Hide” your Work tabs and proceed with your Personal tasks. Then the next day, when you are back at work, you can “Hide” your Personal tabs and “Show” your Work tabs."

On an aside, I'm also getting pretty confused between collections (mobile), containers (desktop), sessions, tab groups, etc... they all seem to have overlapping but different functionality.

Hello, I'd like to open url links clicked from any program in a private tab. Firefox is my default browser. Links open in new tab, which is okay. I browse in private mode all of the time, but clicking links opens in normal tab, then it cashes the content, cashes history etc. Most of the stuff (from for example discord) is a one time thing, silly and probably even useless stuff.

Is there a possible way to force windows10 to use "firefox.exe -private" as the default handler to open firefox ? I don't really mind if it opens a new window instead of new tab as long as it remains private.

Thank You for Your time.

When I open Firefox a tab for gmail opens every time, but cannot be closed (there is no "X" on the right side of the tab). Therefore, when browsing in other tabs, gmail is always open. How can I close it, or better yet, remove from my computer? It does not show up in the list of programs on my computer within the Control Panel.

Hi, recently my firefox was updated and I don't know what happened but it had to reinstall all my addons after the update. But ever since then, my pocket recommendations have not been showing up. I followed the steps in this guide: https://medium.com/@EhsanNazim/re-enable-recommended-by-pocket-section-on-firefox-homepage-and-new-tab-a4df044f9c17

and set browser.newtabpage.activity-stream.feeds.section.topstories to True but still no change. Can anyone provide a solution?

Hello, suddently after upgrading my Firefox Developer Edition to version 77 I noticed that my pinned tabs have sound icon again, which i previously disabled using

browser.tabs.showAudioPlayingIcon = false

Now however I found that it was removed here:

How can i disable this annoying audio icon now ?

It is about pinned tab. I am having a problem about the pinned tabs. I pin a tab in one window. Then I open new window. I close the previous window with pinned tab. Use the new window then close it too. I reopen Firefox there is no pinned tab in new window. it keeps me losing my pinned tabs. How can I solve this problems.

When I'm minimized or maximized the browser, there's these white bars that appear around the browser. If I restart the browser, the bars will be gone for awhile and it will happen again. See attached image for a clearer idea of what I'm saying.

Also, if I minimize the browser completely, I can never open it again until I close and restart the browser. Not sure what is happening.

Problem began with not being able to open a new tab. I updated to FF 78.0.2.

Now I still cannot open a new tab and my tabs are superimposed on my bookmark folders. Clicking on that menu bar opens a folder, not a tab. FF is unusable.

Also, the three coloured buttons, appear down on the webpage rather than in the menu bar. In order to get them out of there, I have to create a title bar that holds only them and the title of the page I'm on which seems a waste of space. Can I get them on the bar next to the search box?

Image attached.

Thanks for any help. Greatly appreciated.

I regularly open links in a new tab to read later, especially for websites that I know will be slow to load (my internet is not great).

For the last couple of months, sometimes when I open a link in a new tab, it loads the link in the tab I'm in in addition to the new tab. If I go to the new tab immediately, wait for it to load the page completely, and then go back to the original tab to continue browsing in that tab, it's fine. If I open the link in a new tab and stay in the original tab to continue browsing further, the original tab will load the link in addition to the new tab so that the link is open in two tabs and the page I was on isn't in any tab. The back button still works, but it is INCREDIBLY annoying.

It doesn't do this on all links, but it consistently does that when I am using my Outlook email via webbrowser, and clicking on a link in the Washington Post email digest to a Washington Post article. For a while I thought it was just some weird thing in the Washington Post emails, but I have noticed it happening on other websites as well, most recently when I was on tumblr and clicked on a gofundme link.

Is this a general Firefox problem? a problem with an extension?

I like to open all urls and links in a new tab because then I don't loose the original tab's contents. So I have set browser.tabs.loadBookmarksInTabs to true. Alas if I click on a link in the history library it still replaces the actual tab. I know that I can do a middle click or a right click to get a new tab but I would appreciate if I could set the standard behavior to open a new tab. Is there a setting for this?

In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

Now j'm writing from Chrome... Firefox is my preferred browser but now it become unuseful... cause frequently crashes every time j open a new tab. My version is up to date ( ver. 78). J have read some topic, and have tried to set conveniently mi firewall/virus module (COMODO), but without no result... can you help me?

Normally, if I click a pdf file on-line, I get the question to open or save. If I choose open, I get a separate pdf file in my Windows task bar to open. Yesterday, this behavior was different. The PDF file became a little icon in the bottom left of my screen, and when I clicked that it opened the pdf in a browser tab. Today this is gone and it is back to its old way. I prefer the tab. Do you know why this happened or how to get that back?

The FF tab bar is so small that it's impossible to grab the window and move it, like to look at something hidden underneath it or make room for another window or app or whatever. The only places I can see to grab the window without accidentally opening tabs or dragging the tab off the tab bar into a new window are at each far end of the tab bar. So you have to decide which way you want to move the window and choose the appropriate end of the tab bar. Compared to Chrome, the FF tab bar is really skinny - even though the difference is only about 1/16 or 1/8 inch, that small difference is enough in Chrome to grab the window where you want and drag it without opening the tab right below where you're grabbing. I hope this description makes sense - hard to put it into words.

Vers 78 has changed the tab drop down combining under an extension, named "Close Multiple Tabs", the functions "Close Tabs to the Right" and Close Other Tabs".

How do I get theses two sub-functions back under the main heading? These are the functions of the tab drop down I use the MOST.

When it became version 78.0.2, the menu to close the tab on the right side was gone and I was very confused. As a result, it was pushed into the submenu. I've been using Firefox because it has a menu to close the tab on the right, but if I can't immediately access this feature, I should consider switching browsers. Please move this menu from sub to main as soon as possible.

Hi there!

My recommended by pocket feature disappeared after the most recent Firefox update. Im currently running 78.01 version. I also tried about:config and the browser.newtabpage.activity-stream.feeds.section.topstories is set to true, but pocket recommendations are still missing from the homepage. Your help will be much appreciated.

Hi all, I just got a new laptop and am trying to get FF the way I like it. This new laptop is W10, and the FF version is 78.0.1.

My old laptop (W7) also has FF 78.0.1.

I created a Chrome folder and a userChrome.css file in my new computer. I copied and pasted the "tabs on bottom" code I have been using on my W7 computer into the new file on my new computer and it is not working.

I have looked all over the web for several hours now and have tried several different versions of the code, tried turning the "legacy toolkit" line (in about:config) on and off and nothing has worked. I also can't find any information on why this code would work in W7 but not W10.

Does anyone have any thoughts?

Hi I attached this to an already solved question and I'm afraid I won't get a response. After update to 72.0.1 Tabs merged with Bookmarks Toolbar. The solved solution of new text for the userChrome.css file doesn't work. The userChrome.css text jdevlin supplied does not work on my Firefox. I had to create a new chrome folder as this update seems to have deleted it. I pasted the text into the userChrome.css but there was no change. What am I doing wrong?

Really need help on this, Firefox is practically unusable like this.

Thanks!
