Diễn đàn hỗ trợ Firefox

I’ve been taking a look at the latest updates regarding the new Firefox design rolling out in Nightly, and while I appreciate the ongoing work and the return of features like Compact Mode, I wanted to share some thoughts from a user perspective, particularly regarding the aesthetic changes.

Personally, I’m not a big fan of heavily rounded edges across tabs and UI elements. For my workflow and visual preference, I much prefer a cleaner, sharper, and more traditional layout.

With these UI evolutions coming down the pipeline, it would be fantastic if Mozilla could provide a built-in option or setting to keep the current/classic style intact while still receiving all the important under-the-hood updates, security patches, and features. Giving users the flexibility to choose between the new design language and a more traditional layout would ensure everyone can tailor Firefox to their exact liking.

Would love to hear how others feel about the new look and whether a classic style toggle would be a welcome addition for you too!

I am making another plea: how do I change the font size of the working bars in firefox? The Title BAR, the Menu BAR, the Tab BAR, etc. On my computer, they're minuscule, and I can't see them. I'm not a programmer, I don't know anything about code, so that limits the way things can be explained to me, or that I can understand. Several of you have been kind enough to suggest different solutions, but they all make things worse. I think I've screwed things up almost irreparably. I can barely recognize my browser any more. I've even tried to refresh Firefox, and that also made the situation worse. And now, every tab crashes constantly. Thanks to anyone who can help me solve this problem.

I have an odd white circle with lines in it at about one o'clock on the Firefox icon in the dock on my MacBook. It just one day and I haven't been able to find any answer in Mozilla/Firefox web pages. I don't know if it means something i wrong or what. Thanks for helping

Firefox popped up an offer to change the screen to dark, which I did. I don't like it, want to change it back. I went to settings but was unable to make the change.

Recently a "gear" icon has appeared on the bottom left of my screen while using Mozilla. It relates to moving the tabs. I don't want to do anything with my tabs. How can I get rid of the icon? The icon reduces the horizontal screen space available. I have a small laptop so this small amount of space is important.

Thanks for your help! Cindy

1. My left-hand sidebar contained about 150 URL links, mostly not bookmarks. I have used this constantly for the last 10 years to access desired websites. 2. After installing 149.0.2 this sidebar with all links disappeared when Firefox was restarted. 3. I tried several suggested remedies such as changing profile or settings on General or Home tabs. None of these were successful. 4. I have seen a portion of my list twice, enough to believe the entire list is stored someplace. It displayed in a box on the Firefox page, but I cannot remember how I produced this list.

How do I get back to having a sidebar full of links?

I have updated to the newest version of firefox, and cannot see the menu bar or search field. I can see everything in a restore down (smaller size window) but I cannot see anything in maximize view of the window....only happens with firefox....everything works chrome and edge. If I click on the white bar it minimizes the window.

For some reason I can not understand the search bar in my toolbar has become so small that it is borderline unusable. No amount of removing and replacing it, fiddling with empty spaces, etc. has any effect on it. Furthermore it appears completely normal sized when I'm editing the toolbar. Does anyone have any clue what causes this?

I like keeping my search bar clean. In addition to the Favorites star, now there is a "add tab to taskbar". On occasion (not sure what triggers it to appear) there is also a "Toggle reader view" icon as well. How can I control what symbols appear in my search bar. I only want what I need not what Firefox thinks I need. Dislike this feature.

When I select Dark Theme, I DON'T wanr to see this. I just noticed this on my Linux Mint desktop machine tonight when I logged in. I also have Dark Reader installed and it isn't affecting ioit eitherit either. Make this go away. It burnsssssss!

Good day everyone,

I have been breaking my head over this for about a week. After the last update that was installed, now my tab width is smaller than the minimum width I have set them to. However, this only happens with active tabs from pages that have an embedded video. At first I thought this was just a thing with YouTube, but it seems it also happens with other video sites. I guess it may be related to whenever the playback button displays in the tab title and it detects there is video content.

I would like to know how to fix this behavior so that my tabs are no longer shortened beyond the minimum width setting.

Thank you in advance.

I want to find out why my browser stacks up my icons in one Vertical column... INSTEAD of a adjustable Horizontal layout...

Why the change, can it be undone...?

I have some code in my .css file that had restored colored folders, a la pre version 89 AFAIR, for the folders on the bookmarks toolbar and in the bookmarks menus off the toolbar. It was working in V138.

I just upgraded to V139 and it's no longer working. I have the plain black/white wireframes back for the toolbar folders on the bookmarks menus.

The code I was using is below. I didn't write it and I confess that I only marginally understand it.

Can someone help me to regaining the colored folders? The white ones are a serious visual impairment for my brain. I need them to be more distinct from the menus themselves.

Some Chinese characters are displayed incorrectly in my iOS Firefox app, with completely different strokes then they should have. It's not traditional Chinese or any other actually existing character, it's just straight up wrong.

As an example, below I am typing 冷 (cold) and it displays correctly in my keyboard (and everywhere else on my iPhone) but when I actually select it, the character looks completely different. If I search, it's still recognized as the correct character, but it's just displayed wrong, making it very difficult to read as these aren't characters that actually exist. This is just one example, with multiple other characters having similar issues.

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.

Dear Firefox Team,

I hope this message finds you well. I would like to suggest a small but useful enhancement to the Firefox interface that I believe would improve user experience and accessibility.

Currently, in the "Customize Sidebar" section, the available tools are limited to a few items such as AI Chat, Tabs from Other Devices, History, and Bookmarks. I believe it would be very helpful to include "Downloads" as an additional sidebar tool.

This would allow users to quickly access their recent downloads without needing to go through the menu or use shortcuts. It adds convenience and aligns well with the purpose of the sidebar — offering quick access to frequently used features.

Thank you for your time and for continuously improving Firefox. I look forward to seeing future updates! Warm regards, Julabeeb a firefox user, developer, and contributor
