During the week of March 7-13, 2026, upgrade(s) caused the size of my bookmarks, fonts and tabs to shrink to barely readable (see attachment) in the Firefox browser window on my Windows 11 PC. I've tried every internet base advice article. How do I increase the size of them?

Hello Mozilla Firefox Support,

I am experiencing an issue with my Firefox browser where my Firefox home page appears very blurry. This has raised some concerns for me about whether something may be wrong with my browser or if my Firefox security may have been compromised.

I would appreciate it if you could help look into this issue or provide guidance on what might be causing the blurry display on my home page. I want to make sure my browser is secure and functioning properly.

Please let me know if there are any troubleshooting steps I should follow to resolve this problem or to verify that my Firefox browser has not been compromised.

Thank you for your assistance.

The size of the slider is so tiny, it is extremely difficult to see let alone manipulate. Is there a setting which would allow a user to make them much wider, thereby easier to see and manipulate? Thanks

How do I get the full url line of where I am currently on the homepage back for the search line, or the old full browser line? Have been looking in settings and haven't located it.

About ready to leave firefox over it, and been here for years.

Thanks,

Michelle

In all webpages, including Firefox settings pages, text appears like poorly chosen Cleartype settings. This does NOT apply to the menu and Address bars, nor the drop down options in "Which topic best describes your question?" that appears when asking a question here. Troubleshooting mode does NOT solve this, however switching profiles DOES, so I imagine there is a setting responsible for this however I've reset all font-related settings I could find. I've attached a screenshot of the result on this page. Choosing alternative fonts does NOT solve this.

On my first PC, I have this specific sidebar icon in my toolbar. When I click it, the sidebar opens with Gemini ready to go. Perfect.

But on my second PC, that specific icon is nowhere to be found. Even when I go to "Customize Toolbar," it’s not in the list of available buttons. The only thing I can use is the generic "Sidebar" button, which is annoying because it doesn't open Gemini directly, it just opens the general sidebar and I have to click again.

I provided an image, where the first icon is what I want, but only second icon is available.

Since updating Firefox from a previous version, the browser no longer displays any Unicode emoji characters. Where an emoji would normally be rendered (👁️), the browser instead displays empty space. Websites such as twitter and discord, which use their own artwork for emoji, are unaffected. This has negatively affected my browsing experience.

For illustrative purposes, I will add a series of emoji and include a screenshot of how they are displayed: (😀🙁😡💀). Other characters still display correctly: (β❖♞䷲⎈𐘢𓀺இ). My computer otherwise displays emoji correctly. The issue persists after disabling extensions, and has persisted between computer restarts.

I'm running Linux (NixOS) and Firefox version 148. I've tested on Chrome based browsers and they work fine. Tested on Firefox forks and they also don't display correctly. This is new since less than a week ago.

Thanks for any help with this.

Hello Again that white stripe at the top of the screen is back this PM: I refreshed firefox yesterday and it solved until now: have carried out the dirty dozen: updated FF yes, clear cache yes etc.

Can anyone help me in layman terms: I checked safari and it was OK there. would prefer FF : I use (have done so since its inception) DuckDuckGo as my home page .

Thank you
