Firefox supportforum

I think it was update, my pc restarted. But it usually asks weird. I lost all windows and all tabs. Yet in library/history under restore windows, there is nothing! There was some json file, from which you could get tabs. I tried it last time and it didn't work. Also firefox wasn't even running at that time and previously i had all windows and tabs... Are you kidding me???

I lost like hundreds of important tabs.... Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa............

When i close my "main" Firefox window and after that the opened popups, this breaks my "restore previous session" setting.

this is not the first time because sometime i forget to close the popups first...

Hello, my Mozilla Firefox is hanging when I have about 50 tabs opened. So I have to kill the browser and restart it. After a few hours of work I have to do that again. Any ideas/suggestions?

Hi,

I just downloaded Firefox on my new PC (laptop) but for an unknown reason opening a link in a new tab doesn't work. Opening a link in a new window doesn't work either, and opening the link in a new private window does not work either. It is getting frustrating to say the least, as I've never encountered this problem before and I have no idea what to do. :)

Thank you kindly in advance for your help!

For last few weeks whenever I open a new web browser in firefox the screen display now open slightly off screen with the top having moved up (and also a little to the right) making the scroll bar barely visible and tabs not visible. I can grab and move sometimes but it has become a consistent problem and I do not know why. Nothing has changed that I am aware of. How can this issue be fixed? Thank you

I HAVE SYSTEM RESTORE ON MY FIREFOX. When I purposely restarted my computer, for an unknown reason, a session came up but my previous session did not automatically restore as usually it does. I did something in that window and was thinking about something else and deleted it, ie: the session. OH S _ _ _! Just lost my restore previous session opportunity..... I opened another session (and restore previous session was grayed - not available) and have not closed my session nor re-started since. Is there any other way to go back and recover my lost session windows and tabs? .... not from the previous session that I accidentally closed, but from the session before that? Thanks in advance. George

When I open a link in a New Tab, Firefox continually returns a blank page. (Previously, Firefox would happily open up to 10 or more Tabs for reading later, without batting an eyelid)

Firefox even declined to open my Home Page a short while ago.

The only extension I am using is Adblock Plus, and even disabling it, or restarting in Safe Mode, makes no difference.

I am using Firefox release 83.0 - and I've tried turning off Hardware Acceleration - again, no difference.

Any help/advice much appreciated Robin

Hi there

since a few weeks it happens daily that by accident I transfer a tab into a new firefox window obviously by moving/clicking the mouse quickly in a way that leads to this new window. then I need to copy the email adress, close the new window and make in the original window again a new tab and paste it there and place it on the right spot. not really handy... not sure what changed in firefox since this did not happen in the past. did there change sth or how better said how can I avoid that this is happening, can I lock tabs that they will not get a new window. does someone know this problem? Thanks Andy

what does a separate tab titled "about:policies#documentation" mean please? It suddenly started showing up as a 2nd tab whenever I open Firefox (Win10) link: about:policies#documentation

After i deleted the cookies and site data i noticed that after i searched something and pressed left-click, instead of opening the website in the same tab, it opens it in a new one and takes them, it is somehing that i do not want, as if i want to open it in a new tab i can just use the middle key to do it.

The + for adding a new tab is located at the upper right hand corner of my Firefox screen. Is there a way to have it show up next to the last tab that was opened? My Firefox at home has the + next to the last new tab. My Firefox at work has it on the upper right hand corner. The attached file shows what I am talking about with the + circled in red and the yellow arrow showing where I would like it to be if this is possible. Thanks.

Okay, so I have the option set in Preferences -> General for "Restore previous session".

However, when I restart the browser, all my open tabs are lost EXCEPT for any pinned tabs.

Does anybody know why this would be?

I'm using 83.0 64bit on Windows 7 SP2. This problem occurs randomly.

I try to open a site; say reddit.com, on a blank tab and it stalls. It never loads. The grey ball on the tab title moves side to site and the page is blank. I open a new tab and type in the same url and it loads fine in the 2nd tab. (The 1st tab is still blank and loading... ) It's not just reddit.com. This problem happens on any sites, Google, vk.com, facebook, etc... When the tab stalls once, it never works with any of the URLs I type in or click from bookmark.

I tried clearing the cache and cookies but it didn't help.

Any suggestions?

Am running FF84.0 on a 64-bit Windows 10 machine. After installing this FF version, I see only the "X" to close the tab, with no "--" to minimize. How do I minimize, rather than close, a tab?

[Both antimalware operations run - Malwarebytes premium trial, and RogueKiller (in Safe Mode) came back as there being no detections / clean, BTW; does that mean any infection hasn't migrated to my PC from FF?]

Tried accessing 'places' file on my desktop as seemingly directed; cannot open with another browser (Opera) nor otherwise - to further clarify, malicious tab in question will not allow me to: close it - by either clicking on its 'x', or right-clicking to use 'Close Tab' option in pulldown menu, nor use the previous page arrow, or return to home / the Google search engine screen, ANY other tab which is part of that session.....is there any way to change the default function so it DOESN'T automatically land every time on THAT precise tab upon reopening, and I can then go to History / previous sites visited to delete? Again, there are a LOT of webpages the links of which I haven't had a chance to copy & paste into an email for myself, and I'm hoping that completely eliminating them all, can be avoided......thanks
