I have set Firefox to not automatically restore the previous session on launch. That is, "Open previous windows and tabs" is unchecked in the Startupsettings.

Most of the time it does not do so, however the previous session will get erroneously auto-restored in the folowing circumstances.

Open a few tabs in a normal Firefox window. Fully quit Firefox (via, for example, pressing ctrl+shift+Q). Open a private window first. Open a normal window second.

What should happen is that the new normal window contains just a single new tab. What actually happens is that the tabs that were open in the previous session get auto-restored in this normal window.

To sum up, there is no auto-session restore if Firefox is launched with a normal window first. There is auto-session restore if Firefox is launched with a private window first, and then a normal window is opened second.

Is this a known issue, and are there any known fixes to prevent the auto-session restore in the latter case also?

After uninstall and reinstall my Firefox i can't restore my bookmark. I used (CTRL+shift+b) and restore my file "JSONLZ4". But i have an error as "Unable to process the backup file". I read your forum and test many things but nothing. I also used the https://www.jeffersonscher.com/ffu/bookbackreader.html,but it does not work? It prompts:failed JSON parsing: SyntaxError: Unexpected end of JSON input. I really need my bookmarks! How can I restore them?

Hi there! After a short elektricity blackout my PC was rebooted and I lost functionality of shortcuts on Mozilla default home page, turning on or off this shortcuts leads nowhere and just move search bar.

I forgot my primary password and a double password system is a pain. I would like to eliminate the primary password, Can it be done w/o losing other data I hope.. Thanks for ANY help Email removed for privacy reasons

I have a D-link 4G Router whose IP Address is 192.168.1.1 Its does not support https, only http.

I am unable to configure it using Firefox, I have to use Chrome. Firefox prevents me connecting to it because (a) It does not support https and, if I get round this issue (b) Firefox reports that the Router's security certificate is out of date

I can never get round (b), there are no options to override Security Certificate is out of date.

I can override the same issue if I use Chrome (but I would prefer to use Firefox)

It seems a bit over-authoritarian to me, to prevent me from logging into and configuring my own Router !!!! I believe Firefox should always provide a mechanism for the user to override these security issues.

I've been able to change some of the Tooltips in my Firefox, but there are still that I can't edit. I've not been successful on Thunderbird at all. Using this in my Firefox's `userCrome.css`:

` tooltip {

   padding:          .5rem 1rem !important;
   color:            var(--light0) !important;
   background-color: var(--dark0) !important;
   border-color:     var(--neutral-orange) !important;
 }

` The "Show your Bookmark", "Open a new Tab", "Back/Forward", "Reload", all of my bookmark websites work. The "Home", "Open application Menu" and "Extensions" still show a black bg w/white text. Switching to a light theme shows the white bg w/black text, so it's a theme issue and not a Operating System (Win 10) thing.

I can't seem to get any of my custom Tooltip colors to show up in Thunderbird.

Any help would be appreciated!

I'm really shocked that the developers at Firefox has not at all fixed the memory leak issue, which caused my PC to crash three times in a row. This is clearly unacceptable; even other browsers I use don't eat up a lot of RAM in a matter of seconds that ends up my PC lagging, or worse, crashing as a result. To the Firefox devs; why are you overlooking an ongoing issue that should've been easily fixed from the get-go, especially with updates that obviously have nothing to do with the memory leak issue? It's really easy to make such a popular browser not hog up memory so easily without causing so much lag, even on higher end PCs.

If the memory leak issue isn't fully resolved by greatly reducing memory usage, especially if I'm only using one or two tabs with me, I will have to consider seeking for another working browser that does not have a memory leak issue, and remove Firefox and never reinstall it altogether.

Can't pinpoint the date, but a while back Youtube won't play videos anymore. It just shows a black screen in the player. Not even the player UI (pause button, volume, settings menu) shows. Just a black portion of the screen. Now when I went in to get a screenshot, it doesn't even show the black box.

For a while now, I've been having recurring issues with Firefox desktop freezing and becoming totally unresponsive. If there's any pattern to what causes it, I haven't been able to notice it; sometimes it happens as soon as I open the browser, sometimes it happens after several hours, sometimes it happens twice in ten minutes, sometimes it happens twice in a few hours (however, I can count the number of days it's happened less than twice in one day in the past few weeks on the fingers of one hand). When the browser freezes, it becomes totally unresponsive - it doesn't fade or display "Not Responding", and Task Manager shows nothing abnormal, but it doesn't accept any input at all, any video or other animated material that may have been displaying freezes, and it can only be "fixed" by force quitting from the task manager and reopening. This is exclusively a firefox issue; other programs open at the same time as the browser freezes are not affected.

The only real lead I have as to what could be going on is that sometimes, things don't freeze all at once, but in a cascading effect. For example, tabs, bookmarks, etc. might not highlight when moused over, but still accept the clicks, or selecting another tab might causes the address bar to display the URL of the selected tab, but the screen displayed in the window will not change. Once these cascading changes start, they generally progress to total freeze before I have a chance to do much with that information (only a few seconds), but it's unusual enough behavior to be worth noticing.

Things I've already tried that haven't fixed the issue:

• Reducing the number of tabs used and otherwise reducing Firefox's system resource usage has not impacted the problem in any way.
• Running in Troubleshoot Mode has not had a consistent effect on the problem (the most recent time I did, the browser ran stably for longer than I could stand to use the internet without my ad blocker, but this is only one data point in an already inconsistent spread; prior instances of the problem have occurred in Troubleshoot Mode)
• Disabling hardware acceleration has not fixed the issue.
• The issue has persisted through multiple refreshes and at least one full uninstall and clean reinstall.
• The issue persisted after creating and switching to a new profile multiple times.
• The issue persisted after renaming places.sqlite
• The issue persisted after clearing cache and cookies multiple times.
• The issue persisted after clearing downloads and history.
• And very likely some other stuff that I'm forgetting, I've been trying to fix this on my own for a while now.

Today I started getting repeated notifications, every 5 to 10 min or so, that my McAfee subscription has expired, my credit card has been rejected, and that my computer is infected. I do not use McAfee, either in Firefox or on my computer. I use the security suite that comes with Windows. I cannot stop these messages from appearing, and disabling notifications from McAfee in the messages does no good, the notifications just keep coming. HOW DO I MAKE THEM GO AWAY? They must be SPAM because I've never had a McAfee product on this machine, EVER. Thank you so much for the help, Dave Templeton

let's keep it as brief as possible.. i have no idea what the hell the degraders of cloudflare are doing, for the past YEARS all sites that required cloudflare worked just fine, and now i lost access to multiple sites on firefox because of the cursed "are you human: captcha loop" i'm looking for extensions, i'm seeking github codes that i don't even know how to execute. the loop keeps demanding me to change the browser to a chromium.. isn't this supposed to be treated as a targeted cyber crime? from google against mozilla? how do i fix the captcha endless loop?

Latest update (127.0.2) erased all my data. Gone are my bookmarks, passwords, sign-in shortcuts, history, etc. and I'm trying not to panic. Most of my passwords are backed up but my bookmarks are gone as is all my sign-in shortcuts, etc.

I always try to keep updated and never have had a problem with anything other than having to relearn a few new things; but this is a first for me.
