Hi,

I have an odd problem with a friend's Firefox and Thunderbird on Windows. The font changed to white in the address bar, the tab titles, some content on websites, some elements of the settings etc.

From what I can see there is no difference to my settings under "Language and Appearance". When I create a new profile either with the profile manager in Firefox or by renaming "%appdata"\Mozilla Firefox", nothing changes. So I can rule out a custom userchrome.css or similar in the profile folder. When I switch to "troubleshoot mode" with the old or the new profile, everything looks fine.

It also affects Thunderbird, but no other programms.

I can't figure out, where the problem lies.

When I check "Check spelling as you type" and choose size of fonts and then close my browser it doesn't remember the settings chosen, IE, when I open it again, go to settings the "check spelling as you type" isn't checked and the size of the fonts shows earlier setting

I tried to use a ftp link setting firefox as the default ftp app, not realizing firefox no longer supports ftp. I am unable to reset the default app and can't find the setting to do so. I downloaded filezilla and wish to set it to be the default app for ftp. Can someone help me with this? Before anyone suggests it, resetting firefox to default settings is not an option.

Hello,

I've recently uploaded a custom-made extension to the Chrome Web Store for my personal use and for a few specific users. It's currently awaiting review.

However, I'm encountering an issue where I cannot download and use the extension myself. When attempting to download, I receive the message "Download failed. Please check your connection."

Although I can see the extension listed on the store (since it's mine), I'm unable to use it personally.

Could you please assist me with resolving this issue?

Thank you.

The AI overviews that I am used to seeing at the top when I ask a question have disappeared. I think it has something to do with the AI controls but I can't figure out how to turn that option back on in Windows 10 Firefox. The only video I found refers to Windows 11 and the screens don't match. Is this feature still available and if so how do I enable it?

Good day,

The old version of Firefox prior to July 26, 2025 opened multiple browsing tabs. These tabs looked like the ones from my toolbar.

When I uninstalled Firefox after July26, 2025 and reinstalled it I opened and still all of the tabs would open again.

I tried to delete the history and still the tabs opened. I refreshed and reset and still the tabs opened.

I do not want to lose saved history or have to delete multiple tabs every time I open the browser.
Thank you

The 'add "outlook.live.com" as an application for mailto links' keeps popping up continuously after I click to X to delete the banner message. How do I disable it? Firefox should have a "don't remind me again" option. I do not want to add mailto links or make any changes. Thank You!

When I hover over tabs, Firefox also displays a text below. So, for example, if I hover over the tab for Google Calendar, a text below shows 'Google Calender - August 2024'. Can I disable the text somehow?

I'm using Firefox Firefox 129.01.

I have an address/search bar at the top of my screen AND one in the center of my home web page beneath the Firefox logo/brand. Currently, if I want to effect a search the Firefox web homepage uses the address bar across to top of the page. I want to set a preference/priority to using the search bar beneath the Firefox logo/brand. Any help would be greatly appreciated.

My son's email messages are being blocked. As far as I know he is the only one. Also, when I try to open a site from the email function, it just keeps searching... This appeared about two weeks ago. I searched for "Blocked Email" and only one has been blocked; a conspicuous spam.

I have for years hated that the right mouse click on a link had "open link in new tab" at the top of the menu, but accepted it as the item I wanted was only the second one down "open link in new window" and it was easy enough with my aging eyes not to have to read the item and have complete confidence that the second item would be selected and would be the item intended to select.

Now, in version 150 you have introduced another item which interfers with my selection.

I detest, hate, the horror of ""Open in Split View." This should NOT BE FORCED ON ME.

I hope in a future version you will allow complete customization of that menu, so that the available items may be reordered as the user needs, especially so I may have "open link in new window" at the top of the menu

I have set my version back to 149.0.2, disabled automatic dates, and will check to see when you have an improved browser with more complete customization possible for users, even ones you do not know.

If "open in split view" had been put lower in the menu, perhaps I would be pleased to explore its usefulness, but you were impertinent and presumptuous to try to force it on me.

Approximately 2 years back, for a short period of time, FireFox let you choose an audio output device in video conferencing web apps, through the web app directly.

This seems to be gone now, but I'd like to turn the feature back on.

It's very problematic to have to change your default audio device for video calls, as your computers sound effects and whatnot will also play in your headset as well, where as before, all you got was the audio from the video call in your headset.

Is there a way to turn this on again? Owl Practice (one of the VC web apps I use) still shows the different output devices, but regardless of which one you pick, it always comes out the default device. For a while this feature actually worked, but now it doesn't.

Is there a setting I can change? Maybe in about:config?

Thanks!
