This is going to be difficult to explain, so I'll do my best;

Recently, Firefox has been exhibiting a problem where, upon maximizing a window, the window extends up by a few pixels more than any other maximized window. Now, normally this wouldn't be a problem as the top of the screen would cut off any extra padding. However, using a program that reserves the screen edge shows that a maximized Firefox window indeed extends past the regular window border by exactly 8 pixels.

What's more, when using Windows Snap on two separate Firefox windows, one of the windows respects the screen edge while the other does not! This leads to the window control buttons at the top right of both windows to be in different vertical positions, which is difficult to use.

No other programs I have exhibit this behavior, which is why I'm turning to Mozilla support. I don't know if the issue has to do with the browser or how Windows 10 renders the desktop, but it throws off the design of the desktop as I intend to display it.

In the provided example picture, the left window demonstrates predicted behavior where the upper border of the window is at the position I intend (40 pixels from the true screen edge), while the right window can be seen extending past the left one by exactly 8 pixels. I have tried this with extensions disabled, in safe mode, and every other way I can think of and the problem persists. No other programs exhibit this issue. This is utterly baffling to me and I hope someone might understand and be able to suggest any solutions.

Thank you!

Firefox 78.0.1 does not remove closed pages from memory - lags and high RAM usage

After updating from 77 (I think it was 77.0.2?) to 78.0.1 I started noticing terrible firefox performance after a few minutes of browsing. My standard browsing habit consists of launching browser with 1 pinned tab and 1 home page (so 2 tabs only), then opening 5-10 tabs from my bookmarks, checking pages then closing them and leaving only 1 pinned page open. In firefox 78.0.1 after doing this (opening and then closing multiple tabs "to the right" using new context menu added in 78) my ram usage does not drop. It goes from 2.4GB (system only usage) to 5.0GB and does not drop after closing tabs. However when I open 10-20 tabs again RAM usage does not rise (maybe slightly, like 5.3GB). So it looks like firefox has multiple tabs stored in ram and opening new tabs just rewrites that memory instead of allocating new one. I have 8GB of ram so 3GB of usage from 1 open tab is crazy. I think it was 500-900MB before. I also have terrible lags because of this - browser hangs up every few seconds for few seconds. I had trouble writing this post with 2 tabs open because of 3.3GB ram usage! Restarting browser helps - ram uasge rises from 2.4GB to 3.2GB only (800MB for 2 tabs) but every new opened and closed tab seems to stay in memory. For example if I open 10 more tabs except for 2 that always open so I have 12 tabs I have 3.6GB memory usage. After I close them it slowly drops to 3.5GB instead of returning to 3.2GB. It does not matter how I close tabs - using right click context menu (close other tabs, close tabs to the right), using X on tabs, or using add-on to close all tabs except for pinned ones. They always remain in memory somehow. PLS fix this ASAP.

P.S. I also tried checking about:performance menu but there is nothing interesting here. It says that 2 opened tabs and addons use 100MB of memory which is not true because browser at this moment uses 1060MB.

Update 1: I also tested safe mode. 3,4GB of PC RAM usage on firefox safe mode start. Opened few tabs, ram usage goes to 4.2GB. After closing all tabs except for 1 ram usage start to SLOWLY decrease but it stops at 3,7GB. Ram usage drop was really slow like 10-30 seconds. It should be instant after closing tabs.

I'm using Windows 10 and just updated to Firefox 78.0.1 last night. Normally, when I open a new tab, I push the down arrow key to bring up my browser history and access my most-used sites. Upon updating last night, I discovered that I can no longer do this. When I press the down key, nothing happens. To get the same result I'm used to, I have to press the space bar, but I've been doing this a certain way for several years and the motion is completely ingrained in me. If I turn Top Sites back on in the options, the drop-down list will open upon pressing the down key, but that of course only brings up the Top Sites. That's not what I want. I tried rolling back to the previous version, 77.0.1, but that didn't fix anything. If I create a new profile, the problem persists. Does anyone know how I can fix this? I know it sounds like an extremely minor issue, and maybe that's true, but I just want to use my browser the way I like using it. I'd appreciate any help/input.

Also, I suppose I should mention that I didn't make any changes to my preferences prior to this issue.

When I m using google doc or sheet to edit a document from google drive, I notice that my cursor will freeze for 5-10 sec from time to time. No issues with chrome on the same documents. I never had this problem until the firefox updates in the past few months. I have tried the usual steps such as disabling all plugins, start firefox in safemode but nothing works. The problem is consistent across all documents, even for new documents. Does anyone know of a workaround?

After my browser being open for a while, usually a few hours, Firefox starts to get some major hanging in some tabs; I can have two windows open, one with a youtube video playing and another with like reddit or something else, and when browsing reddit, I get major hanging when interacting for around 7 seconds.

I recorded a couple performance profiles to see what's causing it, and it seems to consistently be a very long JIT or GC call, also labelled as "Cycle Collection" in the waterfall view.

I saved the profiles and I can upload them, but I'm not sure if they come with any private info so I'm reticent to add it to this thread.

I've watched the Task Manager (the Firefox one and the Windows one) while this is happening and memory usage in the Windows task manager seems to rise quickly over a few seconds then suddenly drop back down. I'm not sure if that's relevant. In the Firefox Task Manager I didn't see anything particularly salient other than energy usage spiking up just after the hanging is over.

This doesn't only seem to happen on Windows because it also happens on my Linux laptop occasionally as well, in a very similar manner. I didn't collect any evidence on Linux yet.

This has been happening for quite a while now, on multiple versions of Firefox in a row. I'm using 79.0b3 Developer Edition right now on my Windows machine.

Closing and reopening Firefox usually causes things to clear themselves out and I don't get such long hanging for a while.

I would expect JIT and GC to happen in much smaller chunks to avoid hanging, it's strange that it takes that long for one call.

Using 78.0.1 on Windows 10, when I press F11 to get full screen in Youtube TV, it works, but it leaves a thin grey line at the very top of my screen (1280x800 resolution showing 1280/720 YTTV), and mousing over it drops down the Firefox tab and URL bars. That's "Full Screen Level 1". Using --kiosk prevents the dropdowns, but it doesn't get rid of the line.

If I play some video and mouse over the Firefox window while it's in Level 1 and not displaying any UI, a full screen icon appears in the upper right. Clicking it gets rid of the gray line and briefly shows the message, "youtube.com is now full screen." Now, mousing over the top middle of the screen displays that message instead of the Firefox UI. That's "Full Screen Level 2."

When I start Firefox, it remembers Level 1, but not Level 2, and the only way I see to get Level 2 is to click on the icon. I want Level 2 all the time for this profile, which I use on a small secondary monitor, and only for YTTV.

Any ideas?
