My Firefox has suddenly stopped working when websites have menus you need to scroll through on the right side. Example: websites where you are drilling down through filter options, or in Ancestry where you will typically open a record in the hints screen and scroll down through the detail. The right scroll navigation causes the whole page to scroll up and down; there's no way to navigate down in the sub-display. I have run FF in safe mode, and done a scorched-earth uninstall/reinstall and the problem persists even with no plug-ins restored. This is on a machine running Windows 11. The machine crashed right before this became a problem. Sites work in Edge without issue.

First image shows me using a dark theme, but address bar still has white background. Second image shows that switching to the light theme makes the text readable. However, I would still like to use a dark theme. I believe I started seeing this issue right when Firefox updated itself to version 100. Any way to fix the bugged address bar color? None of my extension should be affecting the address bar color.

Hello,

Firefox just updated to v100.

However, my menus (e.g., bookmarks, tools, history etc) and popups text has become black, having previously been white. The Menu Bar and Tabs text are still white.

How do I get the White text back on menus and popups please?

Thanks in advance.

I have download set to always ask and consequently always get the, "What should Firefox do with this file?" dialogue box. 9 times out of 10 I choose, "Open with ... ". 10 times out of 10 Firefox also downloads the file. How can I stop FireFox downloading files I don't want ?

Hello,

I am learning to look at websites with help of the development tools and the inspector tab and I am trying to get into how the web works and how the different programming languages interact and so forth. When moving the mouse over parts of the website, the relating code is highlighted in the inspector tab. I am having an issue as follows:

The first image shows a part of the website code. The mouse cursor is on no specific position, I marked its position with a blue arrow.

In the second image the mouse is over the red "free options" button and in the inspector tab a div appears out of nowhere. It does not appear in the code unless the mouse is moved over the button and disappears as soon as the mouse leaves the button. I have never seen that before (maybe because I am a beginner) and have no clue what happens there.

Is that done with javascript? Or with php? Or with css? Or anything else? What happens there and how can the actual code change?

In the inventor tab, does the code have to do with the DOM rather then the sourcecode of the website is that right?

Please give me some light =)

regards p3ppi

In release 100 , why did you not bring my old profile data along??? I'm a computer professional and it was a nerve-racking experience. I can't image how most people could follow your instructions on how to recover from your thoughtless update procedure. I've been through many Firefox upgrades over the years without such effort.

I like to keep shortcuts to my favorite, most often used sites on the New Tab page. One of them, to Yahoo, keeps disappearing, and is replaced by sites that I do not visit very often. How can I recreate a shortcut on my new Tab page to get me to Yahoo Finance?

I uploaded an image of my New Tab page as it currently exists. I used to have Yahoo where the "prime-genetics" shortcut appears. I want to get rid of that one and replace it with Yahoo. Thanks!

SSL_ERROR_ACCESS_DENIED_ALERT I keep getting this on different sites, I can't access lots of pages and it's getting to be a massive problem and I reallly need some help. PLEASE can someone help.

Hi,

I would like to change the light grey hover color on menus (e.g. yellow), see attachments, probably using userchrome.css.

Does anyone know the correct code to do this please?

Thanks in advance.

My laptop set-up is practically identical to that of my PC, but the latter doesn't exhibit the same malfunction.

I've tried anything I could, including reinstalling the browser, removing all of my bookmarks (about 10,000) and addressing extensions (Decentraleyes, Default Bookmark Folder, Disable Tab Detach, Flagfox, I don't care about cookies, Keepa, Notifier for Gmail, Privacy Badger, To Google Translate, uBlock Origin, Undo Close Tab, Video DownloadHelper and Youtube's Annotations No More), but not even safe mode improved the situation in the least. Windows Defender also hasn't detected any malware and my web surfing habits are as safe as it gets.

The only deeper data I could gather is that the problem manifests with a progressive, rapid surge in CPU and RAM usage; the former, for example, is saturated to its total 16 GB in a matter of about 20 seconds.

My laptop is a Dell Inspiron 7586 with Windows 11 64 bit; Firefox version is the latest, 100.0, and, by the way, none of the recent updates has improved the situation.

Thanks to anyone who might come up with an educated guess!

So, I've been trying to login to TikTok using Firefox version 100 but it won't let me login because Firefox seems to send too many requests or something that causes TikTok to restrict my login. Each time I try to login, I get the "too many attempts" message.

What's weird is that by using Firefox ESR (I think it was version 93), I'm able to login to TikTok, but it breaks WhatsApp web's login and sends it to a refresh loop. I've tried to disable all my privacy and proxy settings for TikTok on Firefox version 100 and it does not seem to have fixed the issue.
