I-Firefox Community Forum

Hi. I'm still new to Firefox and don't really know the settings very well. I recently switched over to using it and realized that when I use most drop down boxes the background of the drop down menu is black, but the text is white and the selection box (when you hover over the item) is also white. Making whatever I'm hovering over very hard to see. I'm wondering if I have a strange setting turned on or not?

Settings wise I have Firefox set to dark mode, not the auto. But when I use the auto it still happens. Trying it in safe mode it still happens. Iv tried to research this a little myself. And read something about the proton setting and turning that from true to false. But this also did not work.

Is there any way to fix this? I just need the text to be a different color or the selection box (when you hover over it) to be a different color.

Attached are two screenshots of what I'm seeing

Hello! Appreciate the help I could get. It is rather hard to type when the letters are disappearing as I type it out. I will provide screenshots of my issues and hopefully someone could help me out. I just downloaded the browser and have no idea how to fix the issues. The tabs are constantly flickering in different colors. The letter are disappearing or merging together or sometimes written in bold, crossed out, or underlined. It is making it rather hard to use the browser haha, but let me know what else I can provide to help out identify the issue. THANKS!

I'm using Firefox, updated to version 140.0.4, on my Windows 11 laptop. Since Edge is my primary browser, I normally only use Firefox for two particular websites that don't work well in Edge. Beginning in March 2025, I've had a strange problem with one of those websites. In certain situations, words or phrases pop up in text boxes, meaning that if I want to type something, I first have to delete the word or phrase. Since it's a game website (not a video type game -- actually contract bridge) and the game is somewhat time-sensitive, this is very annoying. The words and phrases are ones that are appropriate to the website (i.e., not random), and seem to be the same in each session. That's why I labeled this as a "clipboard-related" issue.

Clearing the cache seems to help for a short time, but the problem always returns. <Ctrl>-F5 also helps, but seems to work for some text boxes but not others. In fact, <Ctrl>-F5 works for one type of text box, the type that I use most often, for the remainder of that session. But if I use one of the other text boxes, it doesn't help.

If that isn't strange enough, there are two additional oddities: For the other text boxes, the ones that are unaffected by <Ctrl>-F5, if I continue to use them, they eventually stop popping up words and phrases, again just for the remainder of that session.

The other oddity is that I'm using the free version of the LastPass plugin, and every time one of these words or phrases pops up, the LastPass symbol (a red box with three white dots) also appears at the right of the text box. This is completely inappropriate, since these text boxes have nothing to do with logging in or passwords. For this reason, I'm going to try to contact LastPass to ask about the same issue. However, their support isn't very responsive, so I'm hoping that somebody in the Mozilla forum will have a solution.

As I said, the problem only occurs on this one bridge website, and although I've been using Firefox to access it for several years, the issue never occurred before March 2025.

Since a recent update, whenever I try to go to ufc.om, Firefox shows me the error in the attached image. It used to display ufc.com without issues before the update [ don't remember which update ].

Other browsers [ Chrome and Edge ] display ufc.com without issues.

Windows Defender uninstalled the Firefox browser because of a Severe security threat. Is there a threat to installing and using the Firefox application on Windows 11?

When I forward or backward a video on Youtube, using J, L keys, arrow keys or mouse click, or pause & unpause, there is this fade in effect on the sound. The volume isn't constant. Volume starts at low and it gradually increases. I don't have this issue on any other browser or application.

To view my Firefox browsing history, I click the three horizontal lines icon (in the top right corner of the window) to open the Menu panel. I then click History then click Manage History.

How can I make the font larger?

Every time I close a window in firefox while I am connected to ChatGPT I get logged out. It does not save my password. I have to sign in all over again. How can I stay signed in the ChatGPT_

working with miro site using firefox is terrible -

- too long downloading and redirecting - half of times strange errors occurs - https://disk.yandex.ru/i/PFQTbYdKGSKS0Q - no problem with chrome or edge - https://disk.yandex.ru/i/XBY6SIzk_gGBYw - just search all troubles - https://www.google.com/search?q=miro+is+not+working+firefox

If a page is maximized I can not move it - I have to click on the 'intermediate' of the three choices (minimize, intermediate, maximize) before I can move it or resize it.

I have three monitors. It's the same behavior on all three.
