Diễn đàn hỗ trợ Firefox

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.

This problem just started today. I am very angry. what is going on with Firefox? Websites are filled to the brim with annoying ad's. and you tube videos are constantly interrupted with ad's!!!!! What is with all the ad's? This problem has not existed until today. Please STOP this! And, No, I can not just wait a few seconds then click on "skip ads" because I am looking at videos on a computer screen while sitting away from the computer in a chair so constantly having to get up, walk to the computer, click on "skip ads", walk back to my chair is an annoyance! Just stop with all the ads!

Is it possible to move the address bar above or below the Bookmarks Toolbar in Firefox 100.0 (64 bit). If not, can you provide a link to the latest version of Firefox for Mac OS X Catalina (10.15.7) that does not have the address bar on the same level as the Bookmarks Toolbar.

Many thanks.

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 always use the current Firefox on two Macintosh browsers running OS 10.14.6.

Recently (in only one of the computers), if I download a file, a pane containing recent downloads opens in the upper left-hand quadrant. This is distinct from the downloads portion of the "Library" area, and gets in the way of my ability to use Firefox efficiently.

I can't seem to find a way to keep this pane from repeatedly opening up as I download things. Can anyone help?

Suddenly, when I search the web with a topic search term, e.g. "thrombin", I get the error message: 'The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.' Can you help me resolve this problem?

I've tried everything I could find , to add to my userChrome.css or to change about_config, but to no avail .

Bookmarks in Firefox use ellipsis , is there any way to use them in tabs as well ?

Hello! Please, implement the built-in speed dial, like in Opera and Vivaldi. It's extremely convenient and useful, lots of people need this. I've been using Firefox for more than 10 years and I hate your stupid "Firefox Home" page (sorry) on desktop and Android with icons that add automatically and I can't change and locate. It's inconvenient and completely useless. It would be great if you create something like Opera 12.17 or 12.18 had. In addition, please remove the "close" button in the last tab. I know that I can do it via the "config mode" (browser.tabs.closeWindowWithLastTab), but it's not user-friendly. It's inconvenient when you close the tab just to return home, but the whole browser closes. It makes me nervous. Thank you in advance! You are doing a great job, wish you good luck, and hope that one day Firefox will be more popular than Chromium-based browsers.

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,

Since upgrading to FF100, almost all of the 'select' boxes on my webpages have white text on a white (or very light) background, and are only visible when hovered over, see attached screenshot.

How can I rectify this please?

Hi, I tried to download a script but Firefox warned me it had a virus / malware. So I immediately put it in trash, emptied trash, restarted my Macbook and used Bitdefender to scan my Mac. Fortunately it detected no viruses. So I think I'm good (Hopefully!)

But, every time I open Firefox now, a little window appears at the top showing my last download and telling me it had a virus or malware - I'm posting a screenshot of this. I removed it from my history, and cleared the preview panel, but it still pops up. To be clear, this only happens when I completely close Firefox and reopen it, not when I just open new windows or tabs.

How can I get it to stop popping up with this message? Also - one other oddity, each time I open Firefox, it says the time this script was downloaded matches the time I open Firefox (as opposed to when I actually downloaded the pdf - about an hour ago)
