Diễn đàn hỗ trợ Firefox

I don't know if it is the last update, but since this week the scrolling menu on numerous website on firefox become messed up and instead having their usual limited height (like no more than 400px) when there are numerous links in the menu, they now reach the bottom of the windows.

I added some image to explain the problem with two sites: one screenshot show firefox bug, and the other is a screenshot (from edge) to show how the scrolling menu with limited height was supposed to be before the bug.

Also the problem appear even in the debug mode, so i doubt it is an extension trouble. How to solve this problem?

In upper right corner of the menu bar, I have what appears is a shield with a helmet (with red banner). This is followed by ever changing symbols, letters, and numbers . When I mouse over it or manually point it disappears. Removal of the pointer brings it back. This shows up on Firefox and Edge browsers. Does anyone know what this is?

Not sure how to explain this without the images... But I opened up YouTube just looking for some videos and uhhhhhh. I checked on other things in my computer to see if it's just my GPU or some weird graphic thing, but everything that isn't firefox seems to be working OK. It's not that terrible, I'm just really confused.

Why is this happening? And can I fix it? Started like... two minutes ago.

I use Microsoft Outlook through GoDaddy for website-related correspondence. The Outlook sign-in page has a selectable option to remain signed in, which I check. This has worked for years: each time I open Firefox, I have been automatically signed in to my email account.

Until recently.

Now, I am NEVER signed in to my account, even though I check the "Keep me signed in" box at each login.

To experiment, I downloaded Google Chrome and have been using it for a few weeks. I stay signed in using that browser, with no issues.

Any ideas about fixing this issue?

I am trying to use a website (www.gool.co.il) which I use to study and worked for me in Firefox on PC and on IOS a few month ago and now the login is broken in Firefox but works in other browsers is there a way for me to fix it?

Firefox keeps crashing randomly, sometimes at startup, and sometimes just in the middle of a session. Sometimes just one tab will crash, and other times it'll be the entire browser. I ran it in troubleshoot mode and it still crashed, so it's not caused by an extension or anything. It never used to do this before and I don't understand what's causing this issue.

Video play problem on Mac Current Firefox version fails to play videos on my Mac (OS 14.2.1). When I click play on a video on any website, the video is extremely slow to start, then immediately stalls for several minutes at a time. My internet connection isn't the issue I'm getting over 650 MBS. I assume the problem is with Firefox, because both Safari and Opera play videos just fine.

Earlier this week, our local IT expert informed us that while Firefox would still be available, it will have no further development. I am looking at updating my Windows systems to Win11 and would like to know if this is true?

I used to have All tabs helper icon on my toolbar. At some point it disappeared and I can no longer use it. It's still activated when I look at it in the add-ons section but I can't seem to figure out how to put it back on the toolbar so that I can instantiate (i.e. use) it.

I've been using Firefox for the past two years. I go onto www.homedepot.com all the time. Every day, multiple times a day. All the sudden over the past two weeks, it won't load my bookmark. I type it in manually, it doesn't work. I clear cache, history and restart browser. No luck. I restart computer, still an issue. I go into 'private window', kind of loads and then all the sudden freezes. I use Chrome and it works no problem. Then I search the Firefox support forum to find that multiple other people have had this issue over the past five years.

I mean wow, I use Home Depot to buy materials for work plus a credit card account and then to just have it not work anymore on this browser for no apparent reason is crazy. Then to not be able to contact anyone at Firefox regarding the issue is also crazy.

I mean it's fucking homedepot. I know like 10 years ago there was a data breach with them so maybe firefox is protecting itself from them? But then just have a message pop up saying you can't access the site on firefox. No problem. But to have it be so open ended and a continuous problem over years. That's just dumb. How can I trust Firefox with my information and data if I can't even access a basic site with no recourse for solution or understanding or help?

My laptop had windows 10. I backed up both its drives, C and D, in their entirety to an external drive and installed Linux (pop!_os), but forgot to open the browser one last time and export current tabs, bookmarks, passwords, history and so on beforehand. I believe I should have the unexported files in my backup, as the Mozilla folders are there. What files do I look for in the backup of my drives and how do I transfer them to my current installation of Firefox?

When I try to open a new tab, the dot continues to move back and forth but does not load the tab. Sometimes I have gotten the message: "A web page is slowing down your browser. To stop it close the page."

I have tried fixes suggested on the web, but no help, including clearing the cache.

Thank you in advance.

Files will not download. The file is a rfa(revit) file. This is my second day using this web browser..

I have checked setting, to which I switched around to try and troubleshoot. This did not work. I ended up downloading another browser and the file downloaded no issue. Why is this happening? Ant help is greatly appreciated!

For some time I have been unable to open banking and medical portal websites. I have to use Google for these sites. Please help with any setting issues or whatever is needed to get this working again.
