On updating to firefox 155 in widows 10, I lost my left side bar on start up with just blank page and search engine box, with firefox application menu n top right of screen. I would like my Bookmarks menu on left sideof screen with menu drop-down folders containing site tabs contained in left side bar as previously obtained. Can anyone help with this frustration Many thanks, Dickie

When Firefox is running in a non-maximized window, an unwanted empty space appears on the left side of the tab bar, before the first tab.

This space is not present when the Firefox window is maximized. It appears automatically whenever the window is restored to a smaller/non-maximized size.

The issue affects the tab bar layout and leaves a noticeable unused area on the left side of the tabs. I would like to know whether this is expected behavior or a UI bug.

This shield on the search bar is making firefox on win11 unusable for me. I set browser.urlbar.trustPanel.featureGate = false but it still displays. Why do they keep making these changes, it seems like every month there is a new change requiring setting changes,

Since the latest update, the findbar is not displaying for me. I hit ctrl+f and I can type a word and it will highlight on the page, but I can't see the findbar itself.

In my about:config, the only modified findbar preferences I have modified are:

userchrome.floating-findbar-on-right userchrome.floating-findbar-on-right.enabled

I have tried changing them from true to false, but it doesn't fix the issue.

I have switched off the "story" but want to get rid of the overlay for this. How can I do this. It is visually offensive to have this big gray blob in the middle of my screen. I have been loyal for firefox because I do not want this kind of intrusion.

Now when I click on something in Firefox, for example a Facebook post, it opens in full-screen mode, not just in the selected window size. When the new window opens in full screen, it covers other stuff already on the desktop. It's f'ing annoying. How do I choose to have new windows open at the existing window size?

I use the setting brower.search.widget.new = false to customize my search bar. Since the latest update of Firefox (Firefox 154), I noticed that spacing between search results is larger and I don't like it as much. I am hoping to revert to the previous version where the spacing is more tight and easier to navigate. The first pic is Firefox 154 and the second is a previous version (147).

The autocomplete dropdowns for form fields have recently changed appearance, and I strongly prefer the previous, simple design.

The new version has:

• Clock icons next to autocomplete/history entries
• Much more vertical padding, making the list unnecessarily large
• Rounded "pill-shaped" highlighting when hovering over an entry

The previous autocomplete list was much more compact and clean, without the clock icons, excessive padding or rounded hover backgrounds.

Is there currently a setting, `about:config` preference or other supported way to restore the old autocomplete list appearance?

Ideally, I would like to use the previous style:

• No clock icons
• Compact rows with the previous amount of padding
• No rounded/pill-shaped hover effect
• Otherwise retain the existing autocomplete functionality

If there is no setting to restore the old appearance, could an option be added to allow users to choose between the old and new autocomplete UI?

Coming from Vivaldi, and prior to that Opera Presto. I wonder if there is a way to customize the sidebar to get the bookmark folder to "Expand on hover", or to expand the sidebar button to a few pixels on the entire left side, and keep the tabs on top?

I know this was possible last time I used FF, maybe 10 years ago between Presto and Vivaldi. But I don’t remember if it was a browser config or add-on!?

I have just reopened my Firefox and have found that recent changes have suddenly put my tabs right at the top of the window - initially very confusing because I feared that I had lost them. I would like to put them back where I find them easier to work with, how can I do that?

I have zoom set at 170% for web pages but I'm unable to do the same for bookmarks and tabs. Is there a setting that I have missed which does increase their size?
