The pinned shortcuts on my newtab page have all disappeared once again. I've gone to about:config > browser.newtabpage.pinned and my shortcuts are all listed. But only blank boxes show up on the page. It will not accept a new entry when I try to enter one. It goes back to the blank white box. Why does this keep happening? Can anyone give me a Firefox for Dummies way to fix this?? Thanks!

When I logged onto Firefox this morning it asked me to update which I did. When I got onto Firefox all my tabs were gone. Please tell me if I did something to cause this and how to keep this from happening again. I do have it set up to restore tabs when logged off and starting up again. Also please tell me how to get my tabs back! I tried to follow instructions for this but actually didn't have the things they said to click on. Thanks so much for your help!!

Hello, I am using Firefox on a new computer, and I have a bizarre problem that I never experienced on other computers. The 'recently closed tabs' and 'recently closed windows' options are disabled. They are grey, and I can't click them (see image). Also, the 'reopen closed tab' when you right-click one of the tabs is disabled (grey). I have tried to search everywhere why it can happen and found nothing. Any advice on how to enable this option? Thanks

In my location, my only option for internet access is a mobile hotspot with limited data. Consequently, I am always mindful of my data usage when using my laptop. Despite primarily browsing static pages, email, and other low-data activities, I often find my data usage higher than anticipated. The main culprit comes to mind to be videos embedded in news articles. Sometimes, with multiple tabs open, I switch to an inactive tab only to find a video playing. Although I've configured my Firefox preferences not to autoplay videos, it seems that YouTube videos still override these settings.

So, my question is, when a tab is inactive, does Firefox stop all data transfer for that tab in the background? And if not, what are the solutions to stop any background data other than continually closing all tabs?


Also, any suggestions on this topic are appreciated, especially from and to users who also live in remote areas without fiber, DSL, etc.

My old hard drive died I couldn't recover it. I cannot mount the disk to another OS etc. The session files cannot be retrived. However I had over 100 tabs open in Firefox I want to retrieve before the disk crashed. I was signed in to firefox all the time in the old computer.

I now have a new computer, I signed in to firefox and I can recover the bookmarks. But I don't see any option to recover the lots of tabs and sessions from my previous dead disk. It seems there is tab sync options between 2 devices that is concurrently signed in. But I can't sign in to a dead disk. I also can't recover the file.

How can I reteive my old sessions with many tabs? I'm hoping firefox have a way of knowing all my tabs since I was signed in and sync before the disk crash.

I have pinned various shortcuts in the New tab to link to websites I frequently use. I use two different laptops and both are configured the same. However the New tab randomly clears the pinned shortcuts. I have attached two screenshots illustrating the changes.

I'm not aware of anything I do that caused the shortcuts to be deleted. When they are pinned I think they should be there permanently.

So I enabled push notifications for Google Calendar. Every time there's a notification, Google Calendar ask if I want to enable "Switch to this tab" for their notifications. I accidentally turned it on, then I managed to turn it off. Except it now keep asking me if I want to enable it.

Looking at the settings, the only two options available are "Always ask" and "Yes", with no way of just saying no... why?

I have many tabs open at the same time and I'm noticing tabs from Urban Dictionary in particular are automatically changing to suspicious sites, quite a few porn sites in fact.

Is this something Urban Dictionary is doing to direct viewers to sponsors or is there a bug in my FF browser?

Hello Good People,

I installed Firefox a few days ago and it was looking good. I don't like that icon in the top-left hand so I right clicked it and removed it. All was good. However, today there is a blank black space in the corner as if the icon was back (but without an actual icon). It's only a small thing but it bugs me. I want the tabs to be shifted all the way over to the left like they have been up to today. It's triggering my OCD. Anyway, any advice appreciated.

Best Wishes

I have used Firefox for 10 or 20 years and have not encountered this before.

New computer running Windows 11 Home. New Firefox install. If I am writing a message in any forum or social media site, and I need to look-up some info or the name of a place or product and I use another tab to do that, when I return to the original tab, Firefox reloads the entire page again instead of just returning me to the post that was being written without reloading the entire page. It can be a severe waste of time trying to find the post I was in the middle of once the entire tab reloads when the site is a busy place with lots of new and updated posts.

I've been through Firefox settings but did not see anything that seemed to be related to this issue, but perhaps the wording/description of the needed setting wasn't clear.

Firefox preventing Win10 going into sleep mode

Hi I read these articles and they doesnt help to resolve the problem https://support.mozilla.org/en-US/questions/1349609 https://support.mozilla.org/bm/questions/1206172 https://www.reddit.com/r/firefox/comments/ip88y7/firefox_is_preventing_windows_10_from/?rdt=53488

Problem: I have Win10. Firefox 107. I have noticed that if I have opened only regular/textual web pages in my tabs like news/articles then PC goes to sleep after specified time of inactivity. But if I open in the one tab some media content like videoclip/animation/movies and put media content on pause then PC doesnt go to sleep after specified time. PC goes to sleep only by manual command (Start>Sleep). Even If I close the tab with media content PC doesnt go to sleep after specified time. I should or totally close the browser with all opened tabs or manually select Start>Sleep.

Could you help to resolve this issue ?

On the screenshots are shown that some of firefox processes couldn't stop making some activity, every second they make some web request or disk operation. May be this is reason why PC cant go to sleep. But again, this is happen only or some media content is put on pause or some tab with media content has been closed.

Why am I losing my open tabs. I have it set to open where left off.

This has happened about 3 times recently. It is a huge inconvenience as I have multiple windows with a lot of tabs open in each. It is too active and difficult to save them all as bookmarks. I thought if you were signed into your account, that would automatically remember what your open tabs were.

I think it has something to do with clearing history. A couple times that function seemed to stall. Like this time. This doesn't happen all the time though. I can clear data & history, have all my tabs sitting there, and they are restored when I go back in, as usual.

I am going to have to change browsers if this continues because I need all my working tabs, many which I will not even remember, to get back to manually.

I just turned sync on (was reluctant to do that as I don't know all the specifics how it works). My mobile phone open tabs did not wipe out as I feared probably because looks like I'm not signed in there. Might have lost everything there also. But does having sync turned on keep things stored in your account so it can't get wiped out?

Hi, Since few weeks ago, firefox never restores my previous tabs/session (I lost a year worth of tabs..), no matter what/how I tried, it keeps starting with a clean session, not even the history in there. I tried: Deleting profile, creating a new one Resetting Firefox Fully delete FF and delete the profile folder Heck, I even used librewolf, and even FF on linux and also Librewolf, same issue!!

I notice this happen once I enable the sync (login to my account), there's no setting in my account says to never restore the session or something similar.

How to solve it?! I need to have the tabs open again..
