MY FF recently updated to version 1380.1 (64bits) and my Sidebar Bookmarks are gone. That is I have to manually put them back every time I now start FF. I want them to always show when I start FF. When I need extra screen space, I would click the X and they'd disappear for that session. And when I was done, I'd click on View - Bookmarks they'd be reinstalled. And when I shut FF down and returned later, they'd be right there where I need them.

My question is, how do I get back to that setup?

Since update to Firefox version 138.0.1, my last viewed side bar is never automatically displayed upon REOPENING Firefox. I must always > View > Re-select the desired sidebar choice >

How can I get this side bar to re-display automatically upon opening Firefox as it used to in previous versions?

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

I tried to do the fix using userChrome.css but it just didn't work. Am I doing something wrong?

Also the fullscreen animation fix using the about:config settings doesn't work either.

Thanks in advance :3

When you right-click on a window thumbnail, a menu should appear, but instead the window thumbnail just disappears. The screenshots show 1) a Firefox mini-window 2) a mini-window that just disappeared when you right-click 3) a mini-window of any other program 4) the menu that appeared is as it should be Otherwise the browser works absolutely fine for a long time. But this problem causes a lot of inconvenience because I have 2 monitors.

I left my computer for a while, and when I returned and took it off screensaver I started going through my emails when I noticed that the bookmarks on the toolbar are missing. The toolbar is present, and I toggled between only show on new tab, never show and always show a few times, but they're still missing. I even tried bookmarking two webpages, but they were not added to the toolbar. As stated, I have the bookmark toolbar to always show. Firefox just updated yesterday, 4/8/25 to 130.1.0, and I'm pretty sure that they were there this morning, but I can't be totally sure. I noticed my computer had updates available, so knowing updating it would not have any effect on Firefox, I restarted the computer while updating so I could also restart Firefox with a bit of a delay. I had also restarted it twice before without any luck. The only thing I did besides updating Firefox was enabled the sidebar, which I then turned off and still did not have any bookmarks in the toolbar. Any assistance would be greatly appreciated, but I may not be able to view and any responses or make the stated changes until Friday.

Does the recent update Firefox 137.0 retain the separate address bar and search bar? One of the things I hate about MS Edge is that there is no separate search bar. Have not been pleased about the small size of the Firefox search bar the last few years. The user should be able to size it at will.

As the pic shows, firefox android has a terrible performance on android to show the code with Chinese characters using its default mono font. (It seems that the default mono font doesn't contains Chinese and therefore it fallback with what system intended defaultly)

So, what should i do to change the font settings? I've.explorered for the anawer and none of them could work...

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.

I have been looking all over Firefox for the setting to change the icon (was included in the latest update notes) but it’s nowhere to be found for me. Am I missing something?

Hi everyone!

Since last update (136?) when I open a page with a video in a new tab, the width of this tab is very small! Almost half my current tab.

(I don't have another example but does this have anything to do with any "media" on a page?)

I have the width set to 152 for years...

When I play a video, the current tab is reduced. Pause= normal tab. Play= small tab. Pause= normal tab...

"browser.tabs.tabMinWidth should have been adhered to."

I just completely reinstalled Firefox: still the same.

What can I do, please?

The release notes for Firefox for iOS 137.0 mention a new icon picker. Where can that be found? Same question for the new “Appearance Menu”. I don’t see either of these anywhere and the release notes give no details. Definitely have 137.0 installed.

I mean, the tabs size are already bothersome that if you have multiple tabs open it's annoying you can't read the title of the page on that tab. So, you change it manually to size 200 instead of fabricated install as 76.

Who makes sure to change these to different size?

Tab width size config browser.tabs.tabMinWidth

Now, on the latest version, it shrinks on multiple tabs.

WHO IS AUTHORIZING THE RELEASES? I MEAN, DO YOU INTENSIONALLY MAKE ERRORS AND RELEASE THEM?

Firefox desktop on PC version: 136.0.0

I am running with ubuntu 22.04.5 (linux)

I am trying to reduce the width of a panel which is on, say, firefox home. I can easily change the height of a panel (just put the mouse on the edge of the corner or top of the panel. However, when I put the mouse on the edge of either side of the panel nothing happens. I want to reduce the width of a panel and I cannot. Should add that the mouse turns into a resizing thing for all panel - it just doesn't work when trying to change width)

Thoughts?

How can I disable the huge Firefox logo appearing on the top of the default home tab? It is enormous and takes up valuable space. Instead of having four neat rows of shortcuts which all show on a new page (like it used to be) that page looks terrible now. I have tried everything formerly recommended to others asking the same question (about:config, proton, etc.) and nothing works. My current version is 136.0.4 (64-bit). A workable solution would be greatly appreciated. Thank you.

After latest update 136.0, a TB icon showed up in the 'system tray'. I'd like to hide it, I have no use for it. Browsing the settings including the advanced preferences yields nothing useful.

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.
