I like to play cookie clicker and watch youtube on my 2nd monitor and for some reason because cookie clicker is being focused youtube slows to a crawl. Its almost impossible to watch videos on their because of the low frame rate and performance settings don't seem to be helping with their being only 2 option none related to what I need.

I'm basically asking how to disable tab-defocus

Hello,

When FF on my Windows 10 machine crashed FF asked if I wanted to refresh FF. I said yes, and FF reopened as usual with all my tabs. After I closed and reopened FF the next time, it reopened without any of my tabs. I then discovered that FF had unchecked the “Startup Open previous windows and tabs” box, which I had previously religiously monitored to be sure it was checked. So I lost all my previous tabs.

In my sessionstore-backups folder I found the file upgrade.jsonlz4-20 as last in a list of three more recent file names. I then dropped the file upgrade.jsonlz4-20 in the scrounger tool on this site: https://www.jeffersonscher.com/ffu/scrounger.html. It expanded in the big window, and when I clicked on Save uncompressed JSON as text, I see all the URLs run together in a text file.

How can I use this information to recover my tabs, please? If so, how? Or is there a better way to use the Scrounger – or another – tool?

Otherwise if I delete the three more recent file names in the list above the upgrade.jsonlz4-20 file, and restart FF will I recover the missing tabs? If so would I the check or uncheck the Startup Open previous windows and tabs box?

Lastly, can I restore my missing tabs using Windows’ “System restore” tool from 3 days before the crash?

Many thanks for any help!

I recently upgraded to Windows 11. I use Firefox as my primary browser, however sometimes I need to use the MS Edge browser. When I open MS Edge, it automatically closes Firefox and deletes my las set of Firfox tabs. How can get my Firefox tabs to remain? ...and yes I DO have the Startup setting box checked for: "Open previous windows and tabs"

Hello,

I use FF with the setting on start to restore the tabs of the last session.

Now I need a specific tab active/focused on start. (It is a WebRTC for our phone system and if it not focused at start ring tone will not be played)

Is there a way to start with my last opened tabs restored but this specific tab active and in selected/focused.

Pinning this tab seems to load it but WILL not play a ringtone without clicked first. If I end FF with this tab active and therefore the tab is active on next start the ring tone will be played.

But knowing me I WILL forget to click on this tab either on start or before ending FF.

Regards

I am wondering if it is at all possible to adjust the settings when pulling a tab into a new window. For example, if I am running Firefox fullscreen I would like the tab that I pull to be opened in windowed form. I noticed that this is typically the case when using Chromium-based browsers, but noticed that on Firefox it stays in the format as the previous window. (if already windowed the pulled tab will also be windowed) is there a way to ensure that the pulled tab will always be windowed?

I have a lot of tabs open. I like it that way, but if I close a tab the "hidden tabs" feature gets activated. And all the tabs go away. It isn't a huge issue it is just very annoying. How can I disable this annoying feature?

I've tried everything I could find , to add to my userChrome.css or to change about_config, but to no avail .

Bookmarks in Firefox use ellipsis , is there any way to use them in tabs as well ?

My laptop had to do a restart and I have about 10 pinned tabs and I went to open firefox and they are all gone. I've tried to do the restore session but they aren't popping back up. How do I get them back???

I've recently made the switch to Firefox coming from Opera, and there's a few behaviours I'm missing / haven't figured out how to set up to match what I'm used to. Could someone point me in the right direction?

1) When I click an external link (e.g. in Discord) to open in browser (Firefox is now default), it opens the link but it overrides the currently selected tab rather than opening a new tab.

2) Following on from that, clicking the link also doesn't make Firefox the active window. Previously if I opened a new link from elsewhere, the other browser would come to the front. Can Firefox do that too?

I currently have it set so that opening a link in a new tab doesn't switch to that tab. Which is behaviour I want (if I'm doing that in Firefox itself).

My browser just updated to version 100.0 and now there's a big white block at the top that blocks access to tabs and the Minimize/Maximize/Close buttons at the top.

I found a few other articles going back to 2015 with this same issue and the only solution that helped a tiny bit was checking or unchecking the Title Bar box. Unchecking it helps a little bit as you can see in the attached screenshot.

The top of the image is with the Title Bar box checked, the bottom of the image is with that box unchecked.

Any idea how to resolve this?

All tabs (including pinned tabs) have disappeared, but continue to show up in Task Manager (84 tabs showing in Task Manager).

I tried re-booting, but didn't help. Firefox v100.0 Win 10 / 64 bit

Edit: I did a Firefox "Refresh" and all my saved tabs returned.

I don't know if this is a problem with my installation, but websites without specific favicons (e.g.: https://forum.librivox.org/index.php?sid=fd7dca1ba59c207dd25121695677d565) don't have a placeholder icon in the tab. Is this intended behavior? There's the globe icon for bookmarks without favicons, couldn't that be used if a website doesn't have one? I think that would contribute to some visual consistency :)

I have looked across various support forums for information on this, I only see posts regarding favicons and bookmarks, not the tab itself, so apologies if this has been asked and answered already!

When i have like 50+ tabs pinned then firefox breaks and we cannot scroll tabs anymore. Of course closing tabs doesn;t work with Ctrl+W, but then we need some different shortcut for closing pinned tabs (like for example Ctrl + Shift + W) or just you fixing this bug ;) I attach 2 screenshots that show what happens with Firefox when having too many tabs pinned. I can't navigate through tabs anymore.

Recently i found that the memory usage can be very large when watching live-stream,tried many ways to fix but none of them was useful. Then i found the new function of "minimize memory usage" button,it is useful,but not so convenient.Can you please add a new way to use this function? Like: set a number of memory usage(for example 256000KB),when reach this number trigger the "minimize memory usage".Then it will be like "auto minimize memory usage". Or,you can just set an UI button on the toolbar to trigger "minimize memory usage".

Please check my screenshot Pic1:It's the live-stream tab,memory usage 1800+MB Pic2:But it seems not so large in "about:performance"

Ridiculous. FF update wants to remove, change, modify, etc. previous tabs that took many hours to set up. I don't need or want new profiles. Maybe it's all saved but none of the help is useful in restoring my tabs. How can I get some real help? This is a good reason to never use FF.

Firefox has been my default browser since 2004. I have never had a problem with closing a Firefox session with 8-12 open tabs and then re-opening Firefox later and having all the same tabs re-open with the new Firefox session. But now, every time I close and then reopen a Firefox session, it is like I have installed a version update: no tabs are saved. I am not a programmer, I am not interested in looking for obscure files and performing digital surgery. I just want my tabs to open like they have for the last 18 years. In Settings under General my Open Previous Windows And Tabs checkbox is checked. Don't see anything else that is germane. My browser is up to date--latest version.

Why is there now no option to close present tab only when clicking on X. The old (default) warning was excellent. With no warning, clicking the X kills Firefox - and all open tabs. This has lost me hours of work already. i certainly don't want to go down the route of restoring all tabs first. I can't rely on it, for instance, holding all comments made on a form. And for that matter, I wouldn't want that to reinstate a login.

Please can we return to the warning with 2 options Close all tabs and Close current tab only.

I am sending tabs from Firefox mobile to Firefox desktop (Arch Linux) (on a regular base for years). All worked fine. After a new install two weeks ago the Firefox desktop receives the tabs and opens them as supposed. But after a day or three when I open Firefox desktop it opens all previous tabs again together with the newly sent tabs. I deleted the Firefox profile and installed from Firefox sync but the problem occurs. I deleted all devices in sync and added my 2 devices (desktop and mobile) again but it didn't work. Does anybody have a similar problem (and a solution)?
