I'm not sure whether it happens at current version of Firefox or already happened previously, but if you close your Firefox main window without closing your Private window first, all your session tabs will be lost when we launch Firefox again. Is there any way to recover my previous tabs?

"Open previous windows and tabs on startup" doesn't seem to work for me - I check off the right box in Settings. (see attached file) but it doesn't work. I use Firefox as a dedicated app for one project, so would like it to open right at the four pages I always use.

Odd, because this USED to work, but has stopped doing so in the last week.

Laptop using Windows 11 64.

I downloaded the newest version, also signed in and out, but no help.

Thanks.

The option to restore tabs and windows is no longer working for me. I normally have a dozen tabs I work thru every day. Yesterday when I shutdown Firefox, all those tabs were there. Today when I open Firefox it only had to single Firefox default homepage. Checking under History there is no option to restore previous tabs, and the recently closed tabs was empty.

To test, I opened an IMDB page and pinned it. I then went to Wikipedia. This gave me a pinned and unpinned tab. I shutdown Firefox via the "X" to close the window. When I restarted Firefox there was only the default homepage. Neither IMDB nor Wikipedia showed up under recently closed tabs and no option to restore the previous session was available.

I have operated Firefox this way for several years. I don't know why this behavior is no longer being supported.

"Firefox detected a potential security threat and did not continue to www.webmail.ilhawaii.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem."

This problem just occurred for the first time. I contacted the website and they say I need to update the certificate in firefox. How do I do this?

Thank You

my facebook ends after a dozen posts with the error message saying reload bur reload does nothing I still can not scan down my facebook posts this only happens on Firefox no other browser has a problem

I'd like to use different themes for regular Firefox and Private Browsing mode on the same device. It seems like an easy way to keep track of where you are and what you're doing, but I haven't been able to make it work. Is that possible?

Hello,

Since the latest upgrade to 111.0.1 i am unable to copy and paste passwords from IT Glue.

IT Glue has a button to copy details to clipboard and when I do a paste I get [object promise]

I want to use Firefox, not Chrome, for my information transfers to Centrelink etc. Firefox stalls - stays blank below - every time I expect to get further info when I have filled in data. This is not so on Chrome, where the next step is revealed after filling in a segment of info/data.

Specifically, I am trying to pull up a web-site. It is called - http://pi-star/

Can someone help me with the right settings.

Plus, this works on another computer, but not this one.

The IP address I am seeking is wlan0:10.0.0.100

Please contact me if you can help. Thank you. Rick

Dear Reader:

HELLLLLLLP!

I loaded Firefox yesterday using Firefox Installer.exe

The installer loaded to my laptop with Desktop Icon Target "C:\Program Files\Mozilla Firefox\firefox.exe" This has my bookmarks and personalizations, and is synched with the Firefox on my Tower computer in another room

Now my laptop has another Destop Icon Target "C:\Users\FEDER\AppData\Local\Mozilla Firefox\firefox.exe" This firefox browser is new and has none of my bookmarks and personalzations. It is not synched.

My Apps shows only 1 Firefox installed, and it will not uninstall.

How do I remove both of these firefox browsers, remove firefox from Installed apps, so I can load a clean version?

This is frustrating.

We have an intranet site that works fine in Chrome and Edge, but does not load at all in Firefox. In Firefox, an authentication dialog appears, but after entering correct credentials, it just re-shows the same authentication dialog after a few seconds. This repeats indefinitely. There is no useful info (and pretty much no info of any kind) in the dev tools. I have tried Firefox in safe mode, with no changes to the behavior.

What steps can I try to debug this problem?

I've installed a Tree Style Tab add-on recenty. Now I want to hide horizontal tabs from the top.

I tired one solution from here: https://support.mozilla.org/pl/questions/1241745 and a solution from creator itself: https://github.com/piroor/treestyletab/wiki/Code-snippets-for-custom-style-rules#hide-horizontal-tabs-at-the-top-of-the-window-1349 (Hide horizontal tabs at the top of the window #1349, #1672, #2147) But to no avail. Can anyone help me with this?

Confused as to why there 44 instances of FF showing up in task manager. Win 11.

ANy help appreciated.

My PC is running v slow.

No viruses as per MWBytes scan.

I've used the Last Pass application with Firefox for years but recently Last Pass isn't auto-filling anymore. It auto-fills fine with other browsers but has stopped with Firefox within the last week or so. Any help would be appreciated.

I had some problems with Firefox and in the course of fixing things my 1Password extension disappeared.

I'm using an older version of the 1Password extension and have used it for many years, and the extension was working fine in my Win 11 computer before my "fix" of Firefox caused it to disappear. But I still have the 1Password extension executable, so I ran that and 1Password showed up in Firefox - sort of.

The regular 1Password icon looks something like a door's lock, but that lock symbol has been replaced by something that looks more like a puzzle piece. When I click on that puzzle piece I get see the window showed in the 1st image and when I put my mouse pointer in that window I'm asked to "run" the extension as shown in the 2nd image. The 1Password extension works fine but I don't understand why I'm seeing an icon that I didn't used to see and being required to "run" the extension instead of simply clicking on the icon.

I already tried this metod (https://support.mozilla.org/en-US/questions/1221406#search), where i set devtools.selfxss.count to 0 and restart the browser, but still cant paste things in console.
