As described, I (changes being intended as temporary) changed the maximal size for the sidebar to open upon hover. Only when, at that length, I try to revert the change, the sidebar closes before I can "grip" the edge of the sidebar to shrink its length.

My issue is not that I cannot fix this change. My issue is that my change isn't permenant. I followed the standard steps of "Right-click anywhere on Sidebar > select 'Customise Sidebar' in menu > let Sidebar collapse > in 'Customise Sidebar' panel deselect 'Expand sidebar on hover' option > close 'Customise Sidebar' panel > pick up the RH edge of now stationary Sidebar by hovering mouse until the 'gripper' symbol (double-headed arrow) appears... drag RH edge of Sidebar to desired new max-open width."

The issue is that, after doing this, the sidebar reverts to taking up half the screen once I re-enable "Expand sidebar on hover" and reversing the steps listed above.

Any help would be appreciated! I'd rather not have to re-install.

Today all of a sudden the size of tabs, toolbar, and sidebars on Firefox became so tiny that I cannot read them anymore. And although I can adjust the font size of each page I cannot do the same for the tabs, toolbar and sidebars. It has become unusable to me this way. I need a magnified glass to see what tabs I have open, to search or access the toolbar and sidebars. I hope you can tell from the screenshot how tiny they have become. Please help.

The mouse cursor does not highlight text in the address bar. It is selecting the text but the blue 'select' highlight doesn't show so I'm working blind. Firefox 154.0b5 Build ID: 20260731090442 (64-bit) on Windows 11 Home 25H2. Build 26200.8875 Tested in troubleshoot mode - same issue.

No point adding screenshots to show an invisible select highlight.  :-)

Name Firefox Version 154.0b5 Build ID 20260731090442

I do not have the function to customize my display screen to dark anymore after the last update, why? The screen shot below used to be a White on Black screen before the last update now it Black on White and I cant change it back

Updated to Firefox 152.0.1 and I've noticed about:privatebrowsing now has a very bright garish (subjective) purple background; I'd like to replace this with something else.

Here's what I've tried so far:

• Adding the css in this 2023 reddit post to my userchrome.css
• Fiddling with about:config, per Ty and James' replies in this similar 2022 question
• As a sanity check, directly editing the style element of the body tag in the inspector to check if `background-color: #424242` the css works. (obviously doesn't stick, see first point)
• As a second sanity check, changing the colour in the userchrome.css to fuchsia, as I'd read in older articles there'd sometimes be a flash of colour before something else was applied and bright pink is easier to see than grey
• Changing the Firefox theme from System theme (Auto) to Dark, Light, and then Firefox Alpenglow to see if that would change the background colour (it doesn't).

I do see that Alpenglow theme now matches about:privatebrowsing shockingly well, but it's not my preferred flavour of utilitarian blacks/dark greys.

Tried to show what I'm after, screenshot of about:privatebrowsing in a split view next to about:newtab. Other than above, the only other things in my userchrome.css are some styles to attempt to return curvy tabs edges.

I just updated Firefox to version 152. Now my bookmarks toolbar is broken. Can't open any site from that toolbar. Also,, the pinned sites and folders are scrambled one over the other on the left (see picture).

How do I get rid of that new sidebar, the slim section? It is totally wasted space! I just want my bookmarks there without that sidebar taking up real estate. It is totally useless for me! Sometimes you just need to leave things alone.

The Firefox main screen has about 2" of space on 3 ides. The icons are so far down (the 4th side) that I cannot read the second line without moving the page up. Many of the web sites I load are off kilter, mostly NYT and Facebook games which always have to be adjusted to a place where they are on the screen correctly. I have spent several hours searching through forums, resetting , refreshing , changing zoom, you name it. I then repeated the process with Gemini, at which point it seemed I only Made the Google search bar smaller but by now I m not even sure.

Since a recent update, the shortcuts on my home page have moved up higher on the home page.

Previously, they were more in the middle of the page.

Is there any way to move them back down to the middle of the page? It just looks off to me. :)

Greetings,

I'm using & viewing the most updated Firefox browser on a Windows 10 Pro (64 bit), desktop, 24" monitor screen.

With the current updates, the list of bookmarks in my Bookmarks Bar has become very small, skinny & overly spaced, hampering readability.

Though I have learned how to enlarge the bookmarks font size, using the "about:config" & updating the 'layout.css.devPixelsPerPx' attribute, the font still remains very skinny & overly spaced.

Is there an attribute that I can change to alter the Font Style (for example to "Semi-bold") & Spacing of the bookmarks list? If so, please be kind enough to describe the process & I'll give it a go.

If a Firefox Development Team member happens to be reading this post, I'd like to put in a request to add some Bookmarks Bar "FONT EDITING" tools accessible via the browser SETTINGS dialogue, to accommodate readability on ALL the various OS & computer form factors that have proliferated these days.

Thank you, Bruce

the resolution offered to my earlier question about removal of logo did not help and the youtube video also did not help. What am I doing wrong? Please consider me a tech 'idiot'.

Hello,

In Firefox (up to date), the “module” (right-click) that allows for direct translation is great, and I want to thank you for it.

However, do you plan to keep the “Windows 98-style” stamp-like format of the dialog box that opens for much longer? In 2026, on 27-inch screens, it’s honestly very annoying—even if you can zoom in just a tiny bit, it’s a pointless step and not ergonomic at all! It’s the little details like this that make us look elsewhere!

Thank you in advance for your understanding!
