As the subject says, is there anyway to hide the horizonal top bar, when using vertical tabs? The update works fine on Windows, but my extensions and the URL-bar are always visible on Mac, despite the URL-bar hiding on Windows, and the extensions moving to the sidepanel on Windows too. The update is kind of pointless, if I just end up having bars on both the side and the top.

I have depended and supported the use of firefox as my default browser. I have always backed up my extremely large bookmark file in html. yesterday I went to use brouser and my toolbar and bookmarks were gone. after wasting most of my day trying to retreave them. I have tried to import from html file, other browser. I keep getting error message. says cause is file being used by something else. i have tried uninstall reinstall, system restore, disabling all virus protection.plus more. I have had to use edge and chrome!!!!! AHHHH need a solution.

Hello: Thanks for creating Firefox. This is my first question after more than a decade using it. I couldn't find proper information about this. This week Firefox started to show a tiny shopping cart icon over the task bar icon of Firefox (image attached). I don´t know what it's and I can't find the functionality that make that appear. So, How do I disable it? I use Firefox everywhere, and I don't like it, specially in my job's laptop as my boss can occasionally see it and it's obviously not work-related in my case. I use chatgpt to get answers and it points to a "Shopping Assistant" feature, but I don't find it. Is it related? The term is so common that I couldn't narrow down to my specific question (what is it and how to disable it)

I use windows 11 and 138.0.4 (64-bit)

Thanks in advance for help

Each time I shut my Mac off and the next day open it up again, Firefox opens up and there are NO bookmarks on the left side. So I have to do the Command B to get them back up. I have neverf had to do this until recently??????

I have a program which I use exclusively on Firefox and until a few days ago I could open the rtf files which I downloaded on MS Word. Suddenly they won't open. I was told to go to the settings >In Firefox Settings>General, under the “Files and Applications” section, be sure that RTF files are set to “Open in Word” There is no rtf listed there as a file type. Did something get changed recently? This is a massive problem for me. I really hope you can help. Thank you

I'm trying to have Google.ca as my homepage, but Firefox won't let me. It keep reverting back to Google.com Please help. Claude Hamel [edited] @gmail.com

I lost all my tabs groups with the the update to release date for Firefox 138.0.4 on the 2025-05-19. Tab groups are still configured but my sessionstore.js is missing. I notice that there is a backup in Session-store backups dated the 2025-05-19 so I presume the tabs groups are still stored there. Can anybody suggest how to get the tab functionality back? I'm hesitant to just restore the sessionstore.js -- the actual tab group functionality is gone. I can't even recreate the groups.

I would like to be able to view the names of tabs and the address bar. I am able to adjust the page views and all is well there. I do not want to use stronger glasses just to view the tabs and address bar and then switch to another strength of reading glasses.

为什么 Firefox 115esr 会把 User Agent 中的 Windows 版本号强制设为 Windows 10？

我是在 Windows 7 下使用 Firefox 115.xx.x esr ，不知从哪个版本起发觉 User Agent 中的 Windows 版本号强制设为 Windows 10 ，请问这是为什么？ --- I am using Firefox 115.xx.x ESR on Windows 7, but I noticed that starting from which version the Windows version number in the User Agent is forcibly set to Windows 10. Can you tell me why?

Hello,

I’ve noticed that Firefox does not show the translation icon in the toolbar for a webpage, even though the page is in English. When I manually go to "Application Menu" → "Translate Page…", I receive the message: "Translation is not available for this page - Sorry, this language is not yet supported." However, if I click on "Change source language" and manually set it to English, the translation works correctly. It seems like Firefox is not detecting the language of the page automatically, and as a result, the translation feature does not appear unless I manually intervene. The issue occurred on this page: "https://mantisbt.org/docs/master/en-US/Developers_Guide/html-desktop/#dev.contrib.submit.before".

I also looked for a way to report this issue, but I only found a form for reporting incorrectly translated words here: "https://docs.google.com/forms/d/e/1FAIpQLSdoRWnsHX6vVnGIRyLi4Kl-p0GrmeVIioqWsTz3aVTRfLScng/viewform". There doesn't seem to be an option to report entire sites where the translation does not work at all.

I'm using: Firefox Desktop 138.0.4 (64 bit) on Windows 10 22H2. Thanks for your help.

When I open Firefox on my computer, I get a blank page for my home page. I have attempted to change my home page using the drop-down choices, except for blank page choice. No luck! Help.
