Diễn đàn hỗ trợ Firefox

I don't remember when it started but text that wasn't underlined before such as: Names of shortcuts in new tab view Titles of YouTube videos on home page, and recommended while watching a video (not on the video itself) Reddit titles and usernames (old UI)

I have checked settings as best as I can and tried disabling all extensions but still have the issue.

There is a left side hidden toolbar that has history AI etc pictured below. I removed it on another computer by mistake and can't figure out how to get it back. It is on a Windows 11 machine. Thank you for any help.

It looks an update occurred but now my bookmarks Column has a white background with white type. I can't read anything there because its all the same color how do I change the background to black?

Since a few months ago the newtab page layout has been changed. The site icons are now smaller, leaving a wide margin on the page. In my opinion this margin is too wide and looks strange. Is there any way to change it back?

See the OLD and NEW layout in the uploaded images.

Hi,

I'm having an annoying glitch since the recent Firefox update. Now, when I am looking at a webpage the tabs at the top of the screen disappear and the webpage automatically maximizes and, to see your tabs you have to hover at the top of the screen to see them again. I do NOT want that! I want to see my tabs at all times! How do I change the settings so that I can do that? I sincerely hope that this "improvement" can be deactivated!

Each time I open Firefox a black symbol appears in the upper right of the Firefox Icon. This began several days ago. What does the symbol mean? See attached image. Is there a way that I can remove this?

I'm using a Windows 11 laptop with a 14" laptop with a 1920 x 1200 resolution. I'm looking for suggestions and tips about the best layout to maximise the display of content in Firefox with the minimum amount of scrolling.

Thank you.

I was experiencing that one bug that locks the sidebar from opening on hover (even with the option enabled) and I was somehow able to change the size of the sidebar while trying to get it to start working again (IDK why I didn't just close and reopen my browser because I know that fixes that) and now my open on hover sidebar is the biggest it can go and it is genuinely unusable. I can't change the size of it while it's on the open on hover option, but changing it back to the fixed/static sidebar and then editing the size does not carry over when I re-enable the open on hover option. Objectively, this is really dumb and kind of hilarious. I know I am dumb for this.

146.0 (64-bit) Windows 11 December 11, 2025 Turned on computer this am, Firefox webpage popped up telling me about what is in it's future but now my side bar is black print on really dark background. Help!

Really odd. I tried restarting and it didn't help.

All of a sudden it was double spaced and the icons look different, too. I checked and my font selection is the same: Helvetica.

I'm attaching a screen shot.

Suggestions?

Hello, after ff updated, gray line appeared. It does not disappear after changing theme. I am using laptop and a monitor. On laptop browser window goes fully to the top, but when i drag ff to the secondary monitor, gray line appears. I will attach photos.

popped up after an update, not only is it slightly distracting but also annoying as now when i try to pick up or select a tab by putting my mouse at the top of the screen it does nothing, as i select the useless black bar instead

Hello,

I just set up a computer with Debian 13 'Trixie', and I downloaded and installed the latest Firefox for Linux (version 145) from Mozilla's site.

Then I noticed at first that it wasn't following my GTK theme. Then after testing a bit, I discovered it would respect only themes with names that end in "-dark". I've taken some screenshots and attached them to demonstrate the problem.

firefox-esr from Debian's repositories didn't have this problem. But also, I've got another computer that still has an older distro (Debian 11) installed, and I'm running the latest firefox 145 on that too, and it always respects my GTK theme regardless of whether its name ends in "-dark". So, perhaps this is a GTK/GTK4 problem or something?

Does anyone know about this issue, can anyone help? I would really like Firefox to respect my choice of theme regardless of whether the theme's name ends with "-dark" or not.

Hi! ...I would like to get rid of that little icon/button (because I already have Fifo on mobile, thanks!) How can I do it? Regards and thank you
