When I first open Firefox from my home screen it opens up minimized in the top left corner and I have to click the minimize button and then the un-minimize button to get it to open full screen.

Thanks, Patrik

Firefox browser is not responding. I cannot click the menu as suggested because when I do the whole page crashes. How do I fix this "firefox not responding" issue?

Why does Firefox has 13 processes open here and taking 700mb of memory. I went away for 2 minutes and when I left it has 6 processes and was taking about 300mb and then I came back to this.

Hi, I use the apple iCloud calendar on Firefox. iCloud calendar has recently updated and now I can't use backspace when editing events in the calendar. It isn't a problem with other browsers such as Google Chrome. Other people have had similar issues, posted on an Apple forum.

I've noticed this issue happening randomly, some of my toolbar bookmarks listed on the sidebar just up and disappear from view. As if they were never there. But I know they're still saved because when I click to Manage Bookmarks and check them there, they show up fine. The toolbar just randomly hides them for whatever reason, and I can only fix it by closing Firefox and opening it again.

I'm on the current version. I remember accessing about:support and clicking on Verify Integrity while trying troubleshoot some other issue, but don't know if that could've caused it though.

Recently Youtube refuses to play any videos for me, saying adblockers are against their rules. I have uninstalled Adblock, and reset firefox totally. Youtube is still blocking me. It works fine on Chrome. Do I have to switch to Chrome permanently?

For the past few days, when I try to log on to PlayStation on Firefox, the sign-in page sits on a loading swirl after inputting email. There's a clear memory leak shown on Task Manager. The menu bar's right-click doesn't draw properly. FF can't be closed and needs to be terminated. The only extension I have is uBlock Origin disabled for this site.

This website works on Edge.

Attached is the broken menu from right-clicking the menu bar.

Firefox uses too much memory, sometimes 20GB on a 32GB Windows machine. It's usually one or two threads which are hogging incredible amounts of memory. This time I had about 30 tabs open.

Today I tried Firefox about:memory "Minimize Memory Usage" several times, and it was largely ineffective.

I did a "create memory dump file" of one 5+GB bloated thread using task manager, but can't find a way to upload the compressed archive with this report for analysis. Finding a way to report this issue was quite a challenge. It seems most help avenues are now missing/moved, and other reports of this type of issue are "Archived".

I tried killing the 2 bloated Firefox threads and checked for tabs which might be missing or malfunctioning. Everything continued to run normally while more than 10GB of memory was returned to system use. Leaving these bloated threads overnight doesn't improve anything, in fact I can often get up and find my machine is completely out of memory because Firefox consumed it all. My smallest machines have 16GB RAM.

These memory issues aren't new. I've been reporting them off and on for more than a decade. They get better for a few months after reporting, then they get bad again in a few more months. The battle to get memory leaks fixed is continuous while Firefox springs more leaks.

I'd like to give you the memory image I generated so you'll at least have some real data to look at and analyze for this report.

The attached task manager snapshot image is a very minor example of this issue. The numbers keep increasing like there are one or more large memory leaks.

While on michaels.com I click on a product, it goes to the product then immediately the screen goes blank. It also happens when I do a search, multiple products show up, then the screen goes blank. I don't have that issues on other websites. What is going on and how do I solve this issue?

Suddenly when I try to go on Youtube, I get messages that I'm blocking ads. I'm on a Mac-mini using X El Capitan V10.11.6, which is the highest I can upgrade to. I'm using Firefox Browser 78.15 (64-bit) and info shows it's up to date. My old Safari browser still will work with Youtube, but Foxfire is my go-to browser.

Running Firefox on MacOS. Browser will occasionally delete previous session when re-opening the browser. I do NOT have the browser set to clear history on closing. I have noticed that two of the incidents occurred when I accidentally closed the default window that opened when restarting the browser but I still had Firefox open.

Really frustrating when I lose all my open tabs with research I was conducting for work.

I just started getting "403 Forbidden" when trying to access dexterlive.com from Firefox running on a Windows 7 PC. It's been working for the last 5 years. I tried with Chrome. It works fine. It also works fine on Firefox running on my Android phone. What's happened to Firefox on the PC?

Hi community, I need your help- Since I installed the last version I click click the top menu with the mouse: - when in a tab, I can't close it with "x" or right click - I can't click to "back" and "forward" buttons - I can't edit the web URL! only by opening a new tab and navigating to a term I want with the arrow keys!

What should I do?

Thank you <3
