In the past month any browsing window I use suddenly goes to full screen and I have to manually reset it by resizing it. Why does this auto-full sizing occur? I can not find a setting that allows this. I just want any screen window I have to stay the way I set it.

Is there away to prevent the auto-unhide of the menu bar in full screen mode when the cursor moves to the top of the screen? I have searched for answers to this and found some old posts about creating a userChrome.css file but I couldn't get it to work.

Here's my use case. I access a remote desktop through Citrix for work. I use a browser via Citrix Lite instead of Citrix Workspace because the desktop will dynamically adjust to the window size when I don't need it in full screen which Citrix Workspace will not do. However, the auto-unhide feature of menu bar when the browser is in full screen mode also causes the desktop to dynamically adjust when it drops down and again when disappears. This forces me pause when trying to work because it happens often since I'm using a a large monitor with multiple applications open with tool bars on the top rows. I know that I can not hide the menu and address bar but don't want to lose the extra screen real-estate. I would much rather have a keyboard shortcut to reveal the menu bar or some other option.

Someone had me do an add-on. I have no idea what the add-on did. Nor do I know how to use the add-on or if it installed correctly. No one gave instruction on how to do what I am asking . So I am stuck with the need to make my scroll bar wider. I need detailed instructions for an idiot on the computer.

The weather widget on the homepage sponsored by accuweather is missing a lot of major cities that were available before October 2025. They are available in accuweather, but for some reason my widget defaulted to singapore, and I can't manually select cities like chattogram / dhaka or even new york even though the are available in accuweather.

every SINGLE time i press the windows key in this browser it opens this menu with. 'file, edit, view, history, bookmarks.

I don't need this useless bullshit and never will. how do I disable it forever.

Hi, Long time Mozilla supporter here. Keep up all the great work for us!! The fonts on my www site are jibberish. Very weird. Note this is only on my Nightly (I keep it updated) browser. Site: https://neilmurphystudio.com/ 1. Image attached showing font display in Nightly regular browser 2. Nightly private browser window displays correctly!!! 3. Regular Firefox (not Nightly) displays correctly. 4. Chrome and other browsers display fonts correctly.

I've tried a few online suggestion. Nothing works so far. Ideas please? I really want to continue using Nightly if possible. My best, Neil Murphy

BTW, I may have more than one Mozilla/Firefox account. How can I check that? Try logging in with the 2 possible emails? This time, I logged in using [email address] I may have an account under [email address]

Thank you!

I want my old Firefox look back! What the heck have you people done and why. Does someone else now own Firefox? I loved it before and now I'm so aggravated I will look at other browsers and even if they are as bad as this "new look" in Firefox, I will switch anyway! Why the heck did you do this and who's brilliant idea ruined my Firefox?

MacOS 26.0.1 Tahoe Firefox 143.0.4 (aarch64)

There is a white border around the webpage content in the browser (screenshot attached). This border exists even in troubleshooting mode, with all extensions disabled, regardless of toolbars or theme, etc. The only place it does not appear is the about: pages (screenshot attached). I've uninstalled and reinstalled Firefox and updated MacOS. The issue disappears when I quit and reopen Firefox but reappears when I resize the window. Is there some obvious checkbox setting I'm missing? I cannot figure out what is causing this. Thanks for any help.

I just updated Firefox to 144.0 On the home page the Firefox logo came back. I went into about:config to check if the update changed the browser.newtabpage.activity-stream.logowordmark.alwaysVisible setting from false to true. It was still set to false so it seems setting it to False is no longer working. Has anyone else noticed this? or Does anyone know any other way to remove firefox logo?

I somehow accidentally removed the Mozilla Firefox Header that has File, Edit, View, Help, etc.. I can not even check for the version of Firefox that I am running. How do I get it back without losing all of my tabs? I could not locate anything regarding this under the Settings area, where it should be located.

how do I get the house tab onto my tool bar? my lap top has it so when I close a window it goes to main Mozilla window. on my desk top there is now house to press when I leave a window it closes the home window.
