Firefox browser problem. When dragging the mouse over text on a webpage to select text I want to copy, some of the selected text and an area of webpage adjacent to the text I'm trying to select is blocked by a box that automatically appears. Sometimes it whites-out a box-shape but usually it's blacks-out. This blocks that part of the page and some of the text I'm trying to select while I'm dragging my mouse and I can't see the mouse while I'm trying to select text within that box. What did I do to cause this and can I change something to make it stop? This is only when using Firefox and I didn't have this issue until October 2023.

Wanted to export some bookmarks, and couldn't figure out why (latest Firefox) Bookmarks "Library" was missing relevant buttons/menus. (Screenshots attached.)

After testing, found they actually are there, but have have almost no contrast vs background - that is when "Manage Bookmarks" is called from a Private window. But things look fine when called from a Standard window. (No extensions; same in Safe Mode.)

Can anyone advise?

A simple workaround is to bring a standard window to the front first, but am curious if this is Firefox on all systems? Only FF Linux? Only the particular (default) settings of my Linux Mint 20.3 Cinnamon installation, and display? Not even sure a Bookmark management window is ever meant to assume the theme of the foreground window (here Private browsing's dark).

Thank you.

my browser continues to show symbols instead of words. I troubleshot the font issue and it does not seem to be that. this is on a macbook pro and the browser is updated. I deleted the browser and reinstalled it. which worked for a day but then everything went back to showing symbols. it is intermittent in that sometimes it will show the real words and then a few hours later is will show this.

Hello there.

I've notice FF in the past month has stooped maintaining scroll position upon refreshing. It was working perfectly until recently. maintain scroll position upon refreshing is a key feature to my work. Please help!

I decided to migrate from chrome to firefox, sadly, my experience has been faced with random slow downs or partial loads even on a fresh install. It's weird but it seems that at random times some websites will refuse to fully load or even start loading, it appears that the app is just hanging. This is usually fixed after several refreshes. Oddly enough, even on a fresh install, if I attempt to load up the same website while in private browsing, it loads right away, again this is consistent even on a fresh install, the attached image was an attempt to load youtube after signing in on a fresh install without add-ons, I tried loading up youtube in private and it worked right away. Chrome wasn't presenting this problem on my computer for years. Any ideas? My computer specs are high enough where they shouldn't matter. I'm running an AMD GPU (7900 XTX) but I haven't found any know issues regarding these, to even discard that, I disabled hardware acceleration, but the issue persisted. Running up to date windows 10, installing latest version of firefox.

Hi there, I have configured Firefox to remove cookies after closing it. At the same time, I have added some webs that I usually use as exceptions, allowing to remember cookies in those. However, I have the following question: if I reject all cookies except for the mandatories ones in a website that I added to my "remember list", does that mean that future entrances in that web will be with only essential cookies?

As an example, if I mark https://www.bbc.com/ as cookies, and the first time I enter I reject all non-essential cookies, next times I enter in the bbc will I be navigating with only the cookies I accepted on this first entrance? Or allowing a site automatically accepts all cookies?

Thank you very much on advanced.

To identify myself I had to scan a qr code on a website using my phone. This used to work in firefox but it doesn't anymore. It still works in edge. I'm using firefox 119.0.1 x64 on windows 11 home 22H2. How can I fix this?

For whatever reason the Picture-in-Picture button keeps not showing up in normal places like Prime, Netflix, Hulu, etc. I can make it come back by going to the Settings turning off the Picture-in-Picture option (Which is always still active) refreshing the settings then going back to Picture-in-Picture and turning it back on and then finally refreshing the video I was trying to use, but this is kind of a lot to have to do every time it happens and it seems to be happening more and more, so I'd like to fix the root cause instead if possible. Any ideas?

I have two PCs, both running the same versions of Firefox for years. A little over a year ago, after an update, a new "Private" icon appeared in my taskbar in addition to the normal Firefox icon on one of my machines, but not the other one. This presented, and functioned as two different, independent browser applications; I could just click on the private browser icon to open the private browser without opening the "regular" Firefox. I don't know where this came from, but I like it... but it never changed on my other PC, and I can't find how to apply it; is there a setting or something I'm missing? Why did it happen automatically on one machine, but not the other?

Hello, I've got a reproduction issue on France TV live programs which I watch through nordvpn. The picture keeps "jumping" fast up and down in a very bothering way. This doesn't happen when the video is NOT live. I run the latest version of LINUX MINT. What can I do to fix it? The only way I found to stop the issue is to take down the resolution of the live video to its minimum which gives me a disastrous picture but stops the "jumping". I guess you might say there is something wrong with my GPU. The point is that my PC is brand new with an AMD 5600G, new MB, 16Gb of RAM and 500w of PSU. BUT more than anything I have to say that everything WORKS FINE with CHROME. I like FIREFOX I have been using it literally for decades now. (I'm 75). Is there a solution? Looking forward to hearing from you. Thanks in advance. François.

Hello, I recently used my MacBook Air to connect with a projector for a classroom presentation. The presentation was using Google Slides. I adjusted the settings to optimize the presentation--setting the navigation and bookmarks bars to hide when in full screen.

I normally use my Firefox browser in full screen mode, but have the navigation bar and tool bar visible.

I cannot figure out how to undo what I did so that my navigation bar and toolbar are visible again when I am in full screen mode. Indeed, when I move the pointer to the top of the screen to make the navigation bar and toolbar visible, I cannot move the pointer back to the navigation bar or toolbar without it disappearing again. Essentially, I need to undo full screen mode.

Thanks, jch

when i go to manage bookmarks i can go to views and sort them by last added, how do i make it, so that when i go to the bookmark drop down menu from the top of the screen so also list the bookmarks in order of last added?

Hi,

I've been using firefox for 10 years and this is the first time this is happening on me. Firefox was working fine but it does not work starting yesterday, simple task like opening and starting a new tab firefox took more than 20 seconds. None of the pages are showing anything, even those about:config pages are not working Every other browsers, like safari and chrome is working perfectly.

I tried to refresh, reset, safe mode, uninstall and deleted library/caches/firefox, library/application support/firefox, but the same problem still occurs.

My specs: macos 14.1. intel 13900kf, 6800xt, corsair vengeance ddr5 48gb, wd 850x ssd

Here is what is showing in terminal. Thank you.

I have macbook. When I open a puzzle e.g. sudoku, the puzzle costantly jiggles about (which I have video of). When same puzzle is opened in PC, ipad or Safari this doesn't happen. Why?

After the last update

When you click on a product on eBay you get a disorganized page.

See they upload image.

I an not having this issue with any other browsers.

Edge, Oprea, and Chrome all work fine.

Any Help?

I've been having this problem for a couple of weeks now. When I go to certain websites (that work on Every other browser I use) I get the following error:

Network Protocol Error

An error occurred during a connection to www.diamondtoolstore.com.

The page you are trying to view cannot be shown because an error in the network protocol was detected.

   Please contact the website owners to inform them of this problem.

It happens with Lowes & Home Depot - two sites I use every day for work. Now I have to use Chrome or Microsoft Edge -YUCK. I went to your help page and tried everything I could find that may help with this issue and nothing has helped. I see that there are a LOT of other people having the problem as well...Can you please fix it.
