Hello all,

I can see that I can access hidden tabs from firefox menu > History > Hidden Tabs. I have non hidden tabs in my permanent session that is saved/reload whenever I close/open Firefox.

I searched in the support section of Mozilla and found that I can use extensions to hide tabs and find these hidden tabs through History > Hidden Tabs to access or simply unhide any of those tabs.

My question is what would be the benefit of hiding any tab? For privacy? If so, is hiding tabs really efficient to protect tabs content and/or browsing history?

I could see that some extensions offer to protect hidden tabs with a password and even automatically unload tabs upon hiding them.

Thanks in advance to shed some light on this hiding feature.

Hello community,

I've been moved to MacOS at work and since then, Firefox will not always restore my pinned sites when I start it the next day.

Here is what I do:

1. Right click a tab, select "Pin Tab"
2. Go about my day
3. At the end of the day, I close Firefox by using command Q and shutdown my Mac
4. The next day, I start Firefox and most of the time, my pins are gone

I did not have this issue on Windows Firefox. I am using MacOS 26.5.2 and Firefox 152.0.4 Firefox says "Your browser is being managed by your organization" in settings. It is a link that can be clicked and the only active policy showing there is "DisableAppUpdate" which I assume is because we have our own tool to manage software updates.

Any idea what could cause my pinned tabs to disappear? I did not really customize the settings so far, I do NOT clear browsing data when exiting FF and the startup option "Open previous windows and tabs" is NOT selected. I have Ecosia and 1Password as plugins.

Any help appreciated, thank you.

I can not seem to find the button to open a saved, closed tab group. I have googled, and there seems to be a lot of people with the same issue. However, None of the information given under those forums provides me with a clear, easy solution. Please help.

In Firefox 152.0.5 under Windows 10, when I hover the mouse pointer over a tab, a balloon pops up showing the text that is on the tab. I find this extremely annoying as I can read what is on the tab. I have searched on the Mozilla site, and I have searched with Google, all to no avail. How can I disable those redundant popup balloons?

Firefox opens as it should but it opens with two additional tabs showing. How do I prevent this. What setting/s do I manipulate to prevent opening multiple tabs on start up? windows 11 / HP Omnibook, new purchase initial set up of FireFox.

Last night Firefox on my laptop performed an automatic Firefox update.. The Firefox that was installed can only display a single tab. This is a major for me, since I normally work with multiple tabs. This problem may impact a large number of Firefox users. The documented recommended fix for this problem did not fix the problem.

7/7/2026 Last night Firefox on my laptop performed an automatic update to the latest Firefox version. The new Firefox has a very bad setting in about;config .. this new Firefox can only show 1 tab ... it is opening up a new tab on top of the first tab, making it impossible to have more than 1 tab ..

This is going cause problems for thousands of Firefox users .. . how I fix this problem ... I tried setting the add tab settings into about;config to add a new tab to the right of the current tab, but my change made no difference ... how can I fix this problem ... does Firefox have a plan on how to fix for this problem for thousands of Firefox users.. this problem will impact thousands of Firefox users..

In the past, when I would click on a link on my home page, the link would open in a new tab, but I would stay on my home page so that I could look at the opened link later. Now when I click on a link on my home page, it doesn’t open in a new tab, but rather opens the link in the same tab that I was viewing my home page on. I have checked my settings, and everything appears to be how I want it. I believe that the "Open links from apps next to your active tab" is the setting that should accomplish what I want. I do have it checked, and yet it won't open my links in a new tab. How do I get links to open in a new tab?

Up until today, when I double-clicked a message in the Inbox, it opened the message in a new tab, and focused that tab so I could read the message. Now it creates the tab, but I have to click on that tab to see the message. (I do not want the preview pane, either). I run 150.0.1 (64-bit) on Windows 11.

I changed the setting to open it in a new window. That had no effect.

If I have a pinned tab, but I close out of the browser completely, that pinned tab should NOT open there when I relaunch the browser. NO tabs should be opened when I relaunch the browser after it has been completely closed.

PLEASE provide a way to disable this annoying "feature" (i.e., bug).

Thank you

How can I get right click to open my selection in a new window? this option has disappeared!

When I right click to open a link in a new window, the top 2 boxes of the right click window are blank and below them is AI stuff, but no open link in a new tab/window! where did it go? How can I get the right click open in a new window back??????

In the previous version of Firefox, there was a location to save current tabs in the "Home" section is that still available? Where is it?

I've attached a photo of the current page, and there does not appear to be a "save current tabs" option

Where is my home screen start up tabs? I used to start up Firefox and my chosen tabs opened. Where are they? That is the reason I have stuck with Firefox all these years.

When adding tabs to a tab group, are the tabs moved or copied into the group?

I have many different interests. I also have hundreds of tabs. I would like the tabs in a group not appear on the open tabs line. I also want selecting a tab group to replace the default open tabs line.

I had about 15 pinned tabs - unloaded - that I was saving for a research project. I shut my PC down and when powered up for the next session - all the pinned tabs were gone. I never thought to record the tabs via screen shot or something.

Is this normal - what are the limits of pinned tabs ? Do they expire in a day ? When the PC powers down ? When Firefox updates ?

Exactly what are the limits or boundaries for pinned tabs ?
