Firefox Community Forum

This has happened twice now - I've had a main window open with 100+ tabs and a second window open with only one tab. All settings are as described to save history, etc. After closing Firefox and later restarting, only the window with a single tab is restored. I've saved the session backup files in another location and manual copied and renamed them into the main profile folder but in each attempt, only the single tab window was restored, which is obviously not what I want. I know the 100+ tabs are in the file because of the filesize and because I've used https://www.jeffersonscher.com/ffu/scrounger.html to scrounge the URLs from the backup file. But the point is that Firefox is NOT extracting the data from this file and restoring the other window, which makes me suspect there is a bug or problem with session restore when more than one window is open at the time of shutdown.

Thanks for any suggestions. Bob

So, despite selecting "Allow Audio and Video" in the Site Preferences, "AUTOPLAY BLOCKED" continues to show on a tab, and it only goes away once I access the tab. This particularly happens on Youtube media.

You may find attached to this question an image of my about:config settings.

What further can be done to fix this?

I played same Youtube video on Firefox and on Edge and Firefox uses way more data(I/O write bytes) I/O writes and I/O Read bytes than Edge. I added the screenshot.

pm: I ran Firefox in Safe mode and with Sessionstore disabled . Some say it is because of History, but I dont want to delete it.

Hello i've been having some problems on the latest software of yours i'm most of the time watching livestreams but from update v.100 of your software it became weird tab suspends after some in activity which is a problem for me

i found a solution through ABOUT:CONFIG and disabled these 3 for videos 1 - media.suspend-bkgnd-video.enabled 2 - media.resume-bkgnd-video-on-tabhover 3 - browser.tabs.unloadOnLowMemory

for videos and live streams it was good it didn't suspend but my problem now since update v.102 is that video plays but the CHAT stops and doesn't reload until i reopen firefox to the front of my programs

although it is runnning in the background and NOT MINIMIZED

even when the live stream has some lags and re-buffer it doesn't rebuffer or refresh the page to reconnect to the live stream until i force my firefox in front of my programs or games and again it was not minimized

if there is an option in the about:config to change this please tell me i'm already losing my mind as i missed one of my friends live stream because of that suspension

thank in advance

While using Firefox all of my non-pinned tabs disappeared suddenly. The History -> Recently Closed Tabs item in the menu was greyed out. How can I get these tabs back? I have not closed the browser yet.

Hello! My computer crashed recently ending my Firefox browsing session along with the 3 windows and likely close to 50 combined tabs I had open. Upon re-opening Firefox I'm pretty sure I clicked "Restore previous session" on the page that pops up with that prompt as I normally do expecting all previous windows and tabs to reappear, but for some reason it didn't load as usual and instead reloaded a new window saying that I'm on the latest version of Firefox with 1 additional blank homepage tab instead of my previous 3 windows with multiple tabs. In that new window the "Restore previous session" option from the menu bar was greyed out and nothing appeared in the "Recently closed windows" or "Recently closed tabs" areas. I ended the new window using the End Task feature in Task Manager and have not opened Firefox back up in hope of being able to recover the now 2 (or I guess 3 if the restore re-load is considered a new session) sessions ago windows/tabs.

I have tried 2 methods to get my previous tabs back: 1) sessionstore-backups subfolder in the Profiles folder - the recovery.jsonlz4/baklz4 are both from the newer blank tab session, the previous.jsonlz4 is from 2 months ago, and the upgrade.jsonlz4 files are also older from 2 months ago so none of those files have the data I'm looking for 2) ShadowExplorer to find an older version of the sessionstore-backups, but this too did not have helpful files from either the recovery/previous/upgrades file types after extracting and seeing only 3 tabs from the older session they logged

Before reopening Firefox again, is there any other method or attempt I should try to restore the now 2 sessions back 3 windows and their tabs? Any relevant help or advice would be greatly appreciated!

everytime I open firefox, it automatically switches tabs like these which require authentication to log in. even though their password is saved, I am still required to click in sign-in button.

Its really annoying that these kind of tabs get opened automatically, and then I have to switch back. Is there a way to disable this autoswitch or better, let the authentication happen automatically since the password is already stored ?

my BT email account used to work fine now I get the email list page up click to open an email which works fine but then when I click a link on the email instead of the link opening on a new tab it opens on the email page which means I have to keep pressing the back button before i used to just close the new open tab

Recently (last month or so) I noticed a new behavior: when I receive PDF attachments via Yahoo e-mail, if I open them using Adobe Acrobat DC reader, and print them, after printing the Yahoo e-mail tab closes. So I have full functionality -- can open the PDFs, print them, everything good -- but then I have to restart Yahoo e-mail. Big pain.

This behavior is occurring on all three of my PCs (two laptops and a desktop), all of which are running latest Windows 11, and latest Firefox, and latest Acrobat reader.

Hello, all:

I thought I could try posting here about finding a reliable tab management extension for Firefox or a program so I can sync the open pinned tabs I have on my laptops and phone with each other so I can be sure to refer to certain tabs when I'm not home or something outside of trying different extensions to see if it'll be done. That way, I can know I can be able to refer to what I need to find rather than having to go home to look on my laptop if I'm not home or something. Thank you in advance if you reply to this.

Hey, I'm facing a problem if I'm opening my website in firefox it can't e open and show the errors. Can someone help me to solve this issue? URL Thank You.

When I download a file from a Yahoo email the tab with Yahoo closes. I can reopen the tab by going to History, Recently closed tabs, but I would prefer for the Yahoo tab to remain open.

Woke up this morning, opened up Firefox and the Trolls have been busy rearranging things during the night. My profile manager disappeared, but I was able to fix that. Now my tabs are out of place and I cannot find what to do to put the Tabs back on bottom, "The way they Should be". Help, please.

Anne,

Also, I am not real computer literate, so draw pictures if necessary.

Thank you.

Hello,

I'm currently trying to log-in on Postman application. This aplication when log-in button is pressed a tab on firefox is open with the postman site log-in. The trouble comes when trying to re-open the tab on another container. It breaks the log-in. To resolve this I would be interesting to some way to choose an specific or default container for new or incoming tabs.
