Quite simply I replaced the dead power supply on an old PC of mine and booted it up to start using it again as a work PC.

When I did the now decade old version on firefox told me I might want a clean reboot which I clicked Ok since the history was so old on it as to be irrelevant. Firefox closed but didn't reboot. So I launched it again and simply chose not to restore the old tabs when prompted (not even some of them as that was also an option). I updated the old version on firefox I had on it before restarting it and logging into my firefox account to sync and try to transfer my work tabs to the old PC. When I did so I realized on the old PC that reopening Firefox didn't reopen where I had left off. I thought it was just the update but did a check nonetheless. Opening a couple of random tabs before exiting firefox and launching it again. It didn't reopen the last tabs. I checked the settings: "open previous windows and tabs" was checked. Did a brief google search that confirmed my next step: uncheck that box > exit firefox > launch firefox > check the box again > relaunch firefox. I did all that and was still not getting my tabs back.

Then I went back to my current PC (where I had changed nothing) and missclicked (I think I was going to the settings) exiting firefox there (3 windows and probably ~60 tabs ... yes I have a problem). And now even on my main PC firefox didn't restore windows and tabs!

I hoped I could go to history > reopen closed windows but no dice. The option is greyed out. That is also when I noticed I had no history whatsoever.

Now I unfortunately relaunched firefox a couple of times here trying to troubleshoot BEFORE I went online and saw that I could have possibly restored the last session using some backups.

With all that in mind can I still restore my tabs/history somehow? And why isn't firefox picking up where I leave it even though the option for it is on?

All of this is on firefox v148.0 on win10 for both PCs if that's relevant.

Thx in advance for any and all help!

Hello Support, Every time I open Firefox browser I see this Google Pop-up to sign in. I want this annoying tracker pop up screen to disappear altogether. I see it on the upper right screen it's very annoying and I don't or use or trust Google at all. I've searched through all settings my search engine is DDgo I see no way of eliminating google pop-up. Why I'm I receiving this and how do I get rid of of it ASAP?

Thanks, ---Dave

On my first PC, I have this specific sidebar icon in my toolbar. When I click it, the sidebar opens with Gemini ready to go. Perfect.

But on my second PC, that specific icon is nowhere to be found. Even when I go to "Customize Toolbar," it’s not in the list of available buttons. The only thing I can use is the generic "Sidebar" button, which is annoying because it doesn't open Gemini directly, it just opens the general sidebar and I have to click again.

I provided an image, where the first icon is what I want, but only second icon is available.

После обновления компьютера закрылись все группы вкладок. Они все есть в разделе закрытые группы, возможно ли их восстановить, если да, то как открыть закрытые группы вкладок?

I’m currently facing a very frustrating issue with Firefox. I have been using Firefox for many years, and it is my favorite and most comfortable web browser for my day-to-day work. I rely on it heavily as all my bookmarks and other important details are saved there.

However, over the past few weeks, Firefox has been crashing more than 10 times a day. I have already tried all the troubleshooting steps available in the forums and through AI support, but none of them have resolved the issue. I also tried installing and using the Firefox Beta version, but the problem still persists.

In our environment, other users and devices are not experiencing this issue, so it does not appear to be related to internal firewall or antivirus restrictions.

Could you please help me troubleshoot this issue? I am attaching the error screen that appears after the crash along with the crash report for you

Long Delay occurs loading multiple websites, from facebook to other sites and I often get a delay of over 20 seconds with any site involving a CDN connection of various types. I am using W11, latest version of Firefox. 148.0 (Says latest version)

When it happens I can see the connection url in the bottom left hand corner includes a CDN part. Settings are Proxy settings "Use system proxy settings"

• DNS over HTTPS is set to "default protection"
• IPv6: ISP is has just changed from gigaclear fibre to toob fibre, but it has made no difference.
• Have cleared cache. No change

This is very frustrating. Started a couple of months ago. I have ended up using Chrome ratherthan Firefox and I am close to giving up with firefox. Help appreciated.

Firefox will only start if I sign in as an administrator. It doesn't connect to the internet, and I can't get to the help screen. I did a refresh but that hasn't help. If I uninstall and then reinstall a new copy correct the problem? How do I save and reinstall my bookmarks and settings? I love Firefox and prefer it over other browsers. But I need to fix it and any help you provide will be very much appreciated. Thank you!

Firefox displays garbled characters, but other browsers do not display garbled characters on the same website.I'm sure it's not a website issue, because more than one website is experiencing garbled text problems. We tried solutions found online, but none of them worked, including completely uninstalling and reinstalling Firefox.

MY PROBLEM IS VERY SIMPLE:"IM TRYING TO OPEN A WEBSITE NAMED SLOW ROADSBUT ITS NOT OPENING AND IT SAYS INTERNAL ERROR 500 SO PLS HELP ME

THANK YOU!

bold text''''bold text' In Settings under Startup, I have check to open all my previous tabs, but when I am shutting down, Firefox wants to close all my tabs before shutting down. If Firefox closes all my tabs on shutdown, then those tabs will not be there next time I start up .... how can I keep my tabs when I shutdown and have them next time I start up

when attempting to login to 53.com credentials are entered, login pressed, login flashes but no login.... as if there is a pop up or something that should occur and doesn't. On edge it works fine, press login and a clock like symbol overlays the login button and then you are in....

I am encountering an issue where, while searching for images on google, the images appear extremely low resolution. When I attempt to open the image in another tab, it remains extremely low resolution and low quality. The issue is not with the images themselves, as I am able to view them on my phone with higher resolution, it is just my desktop that experiences this issue. Please fix it.
