Firefox supportforum

After updating Firefox, I now have a horizontal line across the upper portion of my computer screen. I have uninstalled FF and updated again thinking it would remove it. I have searched for a resolution and nothing has worked for me. I don't want to have to pay an expert to remove the line. Please give me a fix for this as it is really bothersome.

I've recently made the switch to Firefox coming from Opera, and there's a few behaviours I'm missing / haven't figured out how to set up to match what I'm used to. Could someone point me in the right direction?

1) When I click an external link (e.g. in Discord) to open in browser (Firefox is now default), it opens the link but it overrides the currently selected tab rather than opening a new tab.

2) Following on from that, clicking the link also doesn't make Firefox the active window. Previously if I opened a new link from elsewhere, the other browser would come to the front. Can Firefox do that too?

I currently have it set so that opening a link in a new tab doesn't switch to that tab. Which is behaviour I want (if I'm doing that in Firefox itself).

Having any google related webpage open for more than a couple of minutes causes it to disconnect (gmail, calendar). This results in no connectivity to any Google services. Opening new tabs will refuse to load even Google.com. The only fix is to completely close out of Firefox and relaunch. But having gmail open for a few minutes will result in it disconnecting again.

The issue persists in 'troubleshooting mode' as well as after doing a refresh. I have experienced this now for the past couple of weeks on my Windows 10 work laptop. I have also seen this on 2 different Linux machines in the past few days. I had attempted to disable http3 and telemetry settings from an older post I had found, but no luck. Not sure what else to try at this point.

On the page: https://support.mozilla.org/en-US/kb/manage-downloads-preferences-using-downloads-menu#w_downloads-panel-automatically-opens it says: "Downloads panel automatically opens" "Every time you start a download, Firefox will automatically bring up the Downloads panel by default, . . . "

It never used to do that ! Having the Downloads panel drop down and just sit there covering a large part of the page every time I save a little picture is an extreme nuisance ! How do I prevent it from happening ? Please help ! Many thanks !

I've downloaded your new version"100" a few times and have found the same problem as a few others. I've tried re-installing a few times, and even after completely un-installing older versions, including clearing cache data etc., but the same thing happens. Are there a few 'bugs' to fix in the new "100" version or is another browser sabotaging this version in some way? I didn't have problems with earlier versions.

Hello, I have trouble with browsing Facebook, sometimes there is a huge memory leak (please check the first uploaded image), and as you can see in the second uploaded image, after I "end task" the Firefox tab that use a lots of memory, the Facebook tab crashed. The third uploaded image is the addons I have installed.

Is there a way to solve this? I go to about:memory and click on all there buttons in "Free memory" but that seems to have no effects.

Thank you for your time, Tom.

Hello dear volunteers (followers),

After Firefox Update to 100.0, the Theme that I created (JOHN - Light Grey) stopped working properly. More Specific all drop-down and pull-down menus have been transformed to a "white" background color, overcoming the initial created one, which was "dark gray".

So I tried to revise (update) my "Theme". But this became impossible.

In Developer Hub, in Theme Generator there was a (pink) frame warning "the following manifest properties that your most recent version upload used in it's manifest are unsupported in this wizard and will be ignored: properties popup popup_text tab_loading So I couldn't edit the theme and even more I can't finish and save any changes. Well, Is there any skilled user to give me a hand ? I would appreciate too much any piece of advice ...

Herewith I attache relevant screenshots.

Thank you in advanced

Hi, I cant log in to any plusnet pages, this is not just Firefox other browsers do the same. I get a message Secure connection failed. All other websites seem ok. Even private browsing is OK but no PLUSNET. I use Firefox 100 and search with Duck Duck Go. Please help as Plusnet can't. Many thanks I.M.

I have one website, newsleader.com, that says I need to enable Javascript for it to work. It worked yesterday and I didn't change anything. I have done all suggestions to enable Javascript and it shows that it is enabled. This site works fine on Chrome. Thanks

So, for a few months now, the preview panel in Firefox has been popping up with every successful download of a file from online. Its a bit inconvenient because anytime it pops up, it basically tabs me off a page and interrupts my writing or the like. This wasn't an issue last year when after successful downloads, the downloads icon in the toolbar just lights up blue to signify a successful download. The preview panel popping up every time Firefox successfully downloads something (due to reasons, I download files in bulk from multiple sources) is incredibly irritating. The problem goes away when I just remove the download icon/panel from the toolbar entirely. I just wanna know WHY this bizarre phenomenon happens.

Not sure when it began, probably before the current version, i.e. it's not related to the latest update. When exiting, everything seems fine at first but then Crash Reporter pops up. If I try to restart my Windows/PC with FF open, the restarting becomes blocked by Firefox, so I have to cancel the restart and deal with Crash Reporter first.

The same crash happens in Troubleshoot Mode.

I don't have any special security software (aside from Malwarebytes with real-time protection disabled).

Latest reports: bp-3e00592e-2756-43bf-9642-01b550220502 bp-2435de7c-8279-4d85-b151-b94380220502

Signature is different (almost) every time but as far as I remember no crash felt any different from the two crashes above. For example: bp-093ec6db-d0e2-4f05-8dbd-e03b50220429 bp-47c1b14c-cba2-4007-9f53-089fc0220429 bp-f4ca1090-d760-4209-a47f-8d40e0220429 bp-4a506f38-75ac-4f62-b4bc-324f00220429 bp-d9a19762-4234-450e-82ed-d41940220429 bp-1b0e9da0-29e6-4107-ad7e-ed77f0220429

Hi! I did a "refresh" on firefox. How do I recover my bookmarks and passwords? There is a folder on my desktop named "OLD FIREFOX DATA" but I have no clue how to use the information contained in said folder.

Thanks for any help!

How can I stop Firefox from asking for the master password for bookmarks on start up? Often I don't need to use a password. It is very annoying and I think it is dangerous because then if I step away anyone has the use of my passwords. Firefox used to only ask when you needed to use a password to login to a site. I think this change is dangerous.

I can't open Firefox. When I click on the icon Bing shows up. I downloaded the latest version of Firefox, I can't install it because I get the message that I have to close Firefox because it is running. How can it be? I haven't been able to open it for weeks.

I am in the USA. Every time, on any page or website that I need to provide credit card info, when I click in the box to type in the CC numbers/expiration date/CCV, a window pops up as it should (for auto-fill) with my credit card information. In that window, I can scroll over the different credit cards, click on the one I want to use, and it SHOULD auto-fill into the box where the numbers would normally be typed in. Now, the window still pops up and I can scroll over the credit cards and choose one, but when I click on any of the particular credit cards, the auto-fill doesn't work. The boxes in "settings" are checked to allow auto-fill. It worked for months, then just stopped. Thanks for your assistance!

I'm running Firefox 100.0 (64 bit) on windows 10 pro 21H2. I've been using Firefox to access Flightradar24 to view real time flight across the globe. All of a sudden today the map doesn't appear any more . I think they use Google maps and overlay their info.

The maps show properly in MS EDGE and Google Chrome.

I've attached a screen shot of what I get.

Thanks

I was using lightspeed POS and routinely get a dialogue box asking me if i am sure i want to do something. in an effort to save .05 seconds, i selected do not let this website ask me again. this unfortunately broke a site function of doing the thing that requires confirmation and im sure broke countless other functions that rely on that confirmation. how do i undo?

Ive cleared cookies and site data, thinking it was sort of a cookie thing and it would reset, but no avail.
