Firefox Support Forum

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

For a few weeks now, FIrefox will not play DRM content video on this computer. I have tried all the suggested solutions and none have worked. Also, I uninstalled and reinstalled Firefox, but the problem remains. I am very frustrated with this problem and am ready to get rid of Firefox permanently on ALL our computers unless this can be fixed.

Thank you in advance for your assistance.

Hi

When I visit the webpages of the Swiss Federal Post Service

    https://www.post.ch/de/kundencenter/onlinedienste

then the scroll bar will not be displayed even though the page is longer than what can be displayed on my screen. As soon as I return to another URL the scroll bar is visible again when needed.

Does anybody know what I can have a scroll bar also for this webpage?

Cheers, Pepe

I've been having this problem for a couple of weeks now. When I go to certain websites (that work on Every other browser I use) I get the following error:

Network Protocol Error

An error occurred during a connection to www.diamondtoolstore.com.

The page you are trying to view cannot be shown because an error in the network protocol was detected.

   Please contact the website owners to inform them of this problem.

It happens with Lowes & Home Depot - two sites I use every day for work. Now I have to use Chrome or Microsoft Edge -YUCK. I went to your help page and tried everything I could find that may help with this issue and nothing has helped. I see that there are a LOT of other people having the problem as well...Can you please fix it.

I use a public computer that resets itself every night. I want to login to my firefox account so I can receive all my settings, extensions, etc., when I login to sync.

However, when I login to sync, my default search provider remains as Google (the computer's default) and does not change to DuckDuckGo (the settings I previously had synced).

How do I set up sync so that when I login, it pulls all settings, etc., from the cloud, instead of keeping some that were configured locally?

Just pointing out the idiocy of this software... despite having tabs with multiple pages of the same host website open, Muppet-Zilla FireFux starts giving me the old Secure Connection Failed rubbish. Take the link, open it in public of MFF, it opens fine. Even a page that was open fine, try to open a link it, Secure Connection Failed rubbish. Hit the back key, A PAGE THAT WAS OPENED, then Secure Connection Failed rubbish. Yet in CCLeaner, Vivaldi, Chrome, Edge, no issues. So, I guess the message in that is clear - uninstall MFF, never install again. Good to know.

In the Microsoft Store there are all these updates for video extensions like "AV1 Video Extension". Should I be doing these updates? Do they make any difference to streaming video on the Firefox Browser?

Using text boxes such as comment sections in certain sites will "duplicate" the boxes directly over it Scrolling up and down will lock the boxes on screen and leave multiple traces of the text boxes Refreshing the page will remove the boxes temporarily but will happen again Happens inconsistently on multiple websites Site shown under is dcinside.com

For the past few days, when I try to log on to PlayStation on Firefox, the sign-in page sits on a loading swirl after inputting email. There's a clear memory leak shown on Task Manager. The menu bar's right-click doesn't draw properly. FF can't be closed and needs to be terminated. The only extension I have is uBlock Origin disabled for this site.

This website works on Edge.

Attached is the broken menu from right-clicking the menu bar.

everytime you update firefox, i loose my personal toolbar that took me a long time to set up. how do i get it back without all the work? also, what happened to the printer icon in the main toolbar?

Hello, when initiating a request for conditional mediation with webauthn I get the following error:

TypeError: 'conditional' (value of mediation) is not a valid value for enumeration CredentialMediationRequirement.

However when asking whether it's available with `await window.PublicKeyCredential.isConditionalMediationAvailable()` it does return true. Is this a bug?

i use to have firefox or mozilla on my toolbar, do not know how to question or figure out what i am looking,

is it adding tab firefox or mozilla to the toolbar, when on toolbar you would click on firefox for a new tab.

thank you rodney l gandy sr

I've seen other people ask this question, and the stock answer appears to be: a) They may be different subdomains, but they're the same site. b) Just add an extra bit on the end of each user name so you can get at the correct one.

Unfortunately...

a) No they are most definitely not the same site: myFirstClientsDevSite.mytestdomain.com mySecondClientsDevSite.mytestdomain.com myThirdClientsDevSite.mytestdomain.com myFirstClientsUATSite.mytestdomain.com mySecondClientsUATSite.mytestdomain.com myThirdClientsUATSite.mytestdomain.com

You see the problem? Firefox treats all those sites as being "the same site", even though they patently are not.

b) I'm working with a lot more than three clients. Plus, that suggestion is basically "we admit that our product is broken, here's a work-around that a few people may be able to use".

And finally: I'm pretty sure that Firefox used to be able to discriminate between subdomains, so the question isn't so much "how can I get it to work", as "why was it taken away in the first place".

Hi all,

Using: Firefox 119.0.1 (64-bit) on Windows 10.

I seem to having an issue with adding search shortcuts on FF, I am following this guide:

https://support.mozilla.org/en-US/kb/assign-shortcuts-search-engines

But I'm stuck at step #4 as the table seems to be disabled.

This is a personal laptop and has not policies on it.

Thanks for your time and assistance!

I get a blank screen when I try to access my e-mail. Is there a reason you do not want me to access my e-mail? Don't tell me you will e-mail me the answer. I will not get it because you will not let me access my e-mail. This situation has been going on for a few weeks and it is getting irksome. When I call your support people hank up on me.

The box in Settings > General > Startup > Open previous windows and tabs is still unticked.

Does anyone know what could be causing it and how to fix it?

Thanks :)

Hi Firefox Team, I am a university student, and I keep getting these messages below, especially when I am doing research for my assignments; it is painful as time is of the essence. I need your help asap. I have already cleared my cache, and cookies Thank you The connection was reset

The connection to the server was reset while the page was loading.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If a firewall or proxy protects your computer or network, make sure that Firefox is permitted to access the web.
