Hi, I can't change the default hover color of buttons in the navigation bar. It either remains totally unaffected or there appears a larger background image of my color overlaid with the smaller default hover image. Hover on the bookmarks toolbar works fine, except for the "Show more bookmarks" chevron, which behaves exactly like a navigation bar button. I tried these:

1. nav-bar toolbarbutton:hover,
2. nav-bar toolbarbutton:hover:active,
3. nav-bar toolbarbutton-icon:hover,
4. nav-bar .toolbarbutton-icon:hover, #nav-bar.browser-toolbar hbox#nav-bar-customization-target.customization-target toolbarbutton:hover,
5. nav-bar toolbarbutton[open="true"],
6. nav-bar toolbarbutton[checked="true"],
7. nav-bar toolbarbutton[buttonover="true"]

For the past week, my browser does not auto-update. I have to download the update and re-download the browser.

I went into the settings and found the update section and when I clicked "Check for Updates", it kept saying "failed to check for updates". I tried with my proxy-settings on with VPN on, proxy-settings on with VPN off, proxy-settings off with VPN on, proxy-settings on, with VPN off.

This is in my personal laptop, where I am the only and admin profile.

My Firefox used to to auto-update but now it keeps saying I need to download the update, but my browser can't even tell if I have the most current version or not.

Hello, sadly I have the problem since a few days that firefox opens a new tab with the same error every time I google something or click on a new page/subpage etc. The URL on the error page is all the time "https://0.0.0.1/" mentention of course a page loading error. I don't know why firefox keeps oppening new tabs with this URL. I allrady tried to use the clearing function and even reinstalled the software, nothing worked. Maybe somebody can help me solving this problem, it is very annoying to have multiple new error-tabs per minute in a normal work flow. Thanks and best regards, Thomas

I just installed Firefox v125.0.1 on my new desktop and I am constantly being harassed by Firefox suggesting "tips" to me that I don't want nor did I ask for.

Such as this example below, see screenshot. I am browsing the web and needed to open a new tab, and immediately Firefox thinks it is okay to harass me with something that I OBVIOUSLY already know...... searching google from the address bar.

So now I have to stop what I am doing to click the "Okay, Got It" button to proceed. But, that won't stop Firefox from harassing me with the EXACT same tip in a few minutes from now.....

This isn't the only "tip" it harasses me with. It's just the only one I have managed to get a screenshot of for now.

How do I permanently disable this crap?

I have been using the internet and web browsers for 30ish years now. I'm pretty sure I know how to use an address bar by now Firefox.....

I also don't appreciate being harassed by things at all. Since this does the same "tips" repeatedly and they never stop it is absolutely harassment. Why are you showing me ANY tip more than once?????

Firefox 125.0.1 update breaks all self signed certificates

After the latest auto update I can no longer access any of my management screens on my private network with self signed certificates. This is a real problem. I have attached a couple error screen grabs, but ALL of themn are the same. The information link says there is no workaround!

So how do I recover access? Chrome works just fine ... so it is def. a Firefox problem.

Hello!

I would like to develop an application that runs continuously, say, at a panel found in a kiosk. I am considering designing it as a webpage that runs locally through the browser but I would like to prevent the users from interacting with the OS or closing the tab and the browser. Is there a way to lock Firefox in full screen and hide the exit buttons? Alternatively, do you have another recommendation for development that is more appropriate, for instance a native app?

Thank you in advance for your help.

Nvidia RTX Super Resolution seems to only work very rarely or not at all compared to the Chrome version. In some instances it will upscale the Full-Screen Video. It will not interact with windowed videos at all. But it will never upscale a windowed version that exceeds the playback resolution.

Steps to reproduce for windowed videos:

1. Open any youtube video
2. Set the resolution to 480p or lower (as I am using a QHD 2560 x 1440p monitor)
3. Playback the video and monitor Nvidia Control Panel to see if Super Resolution has activated.

Observation for windowed videos: Feature works in Chrome. Feature does not work in Firefox

Full-Screen and Super Resolution: I have no idea what is going on here, on very rare occasions it does work, for the most part it does not work at all. If I had to give a rough idea of when it works, I would say that it is more likely to work when Firefox has been freshly launched.

I could neither see an active change in the Control Panel, or notice anything in the video quality. Both a quality change and feedback in the Control Panel occur when using the feature in Chrome. I have tested on identical links, with identical quality settings.

I tried:

• setting the Super Resolution Quality manually, instead of manually
• an incognito tab

I've just updated to Firefox 125 and now, when I start to type in the URL bar and get my suggestion dropdown of previously visited pages, I no longer can see the actual url for each entry. All I see is the top level name for each entry.

This is not helpful, as I may have perviously visited a number of pages on that site and the information shown does not give me a way to differentiate sufficiently between those pages.

How can I get the exact url displayed on the suggestions dropdown.

How can I get those top level descriptions NOT displayed, so that only the urls are shown?

This has been happening to me with recent updates of Firefox, and I am very close to dumping a browser that I have used for years because of it. I go to load pages and it just sits there and spins and spins. In the time I take to open another browser like Chrome and copy and paste the exact same links into Chrome, where the download of the web page is practically instant. I go back to Firefox and it is still spinning and it is just ridiculous. I have no clue what would be causing this. After it finally loads a page, it seems fine on subsequent loads of pages.

I use a web application that lists items in a table, which provides a link to download the table as a CSV file. It used to work fine in previous versions of Firefox. However, in the current version, while the file save dialog defaults to a filename that ends in .csv and CSV is selected in the "Save as type:" drop-down, the data in the file that Firefox actually saves is in XML rather than CSV format. I don't know in which version of Firefox this behavior changed, as it's been a couple years since I tried to use this feature. Or I suppose it actually could be a new bug. I do know that when I use the same feature in Microsoft Edge, it saves the CSV file in the correct format, so this behavior seems to be peculiar to Firefox, rather than anything wrong with the web application.

Hi friends. We have had some recent power outages when everything was back up running my youtube screen only shows the video but everything else is white. I will try to attach a screenshot.

I am unable to sign the petition because the whole form does not show up in Firefox.

For the last several days I cannot access my gmail on my PC with firefox. I keep getting an error message that says:

"We’re sorry, but your account is temporarily unavailable. We apologize for the inconvenience and suggest trying again in a few minutes. You can view the Google Workspace Status Dashboard for the current status of the service.

If the issue persists, please visit the Help Center »

Try Again Sign Out"

I keep trying, but to no avail. Gmail works with Chrome on my PC. How can I fix this?

I recently updated to 125.0.1 and now get 'failed to check for updates': - when I manually check (help > about Firefox) (see image) - in 'settings' it also shows 'failed to check for updates' (see image) I never had such a problem with previous versions; any suggestions?

I have Windows 11 and the Firefox 124.0.2 browser. I cannot update to the latest version of Firefox. I receive an error message "Failed to update". I've uninstalled and reinstalled the browser, ran the install utility selecting update, nothing seems to work. Please help

Does Mozilla Firefox for Android have plug-ins?

Nothing happens when I press the play, like, dislike, notifications, favorite, or join server buttons. On top of this, when I try to open the catalogue it's just a grey screen with nothing in it. In the attached GIF I am clicking rapidly. I don't believe this is an issue with roblox itself, as when I open chrome everything works perfectly. The only extensions I am using for the site are RoPro and BTRoblox. I have tried to turn the extensions off and have even uninstalled them, however the problem was still not fixed.
