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.

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.

i'm trying to use policies.json to whitelist pages user can visit. When I apply changes, after browser restart I see it reacts (I use correct file), I use the template of: { "policies": { "WebsiteFilter": { "Block": ["<all_urls>"], "Exceptions": [ ....

here is see on adding an exception item - it is allowed, on removing it is not. I have a system running on http://localhost:8090. I tried multiple patterns and none of them allowed me entering my page: "*://localhost:*/*", "*://127.0.0.1:*/*", "http://127.0.0.1:8090", "http://localhost:8090", "*://www.localhost:*", "*://www.localhost:*/*", "http://localhost:8090", "http://localhost:8090/*", "https://localhost:8090/", "https://localhost:8090/*", "localhost:8090", "127.0.0.1:8090",

when changing: "Block": ["<all_urls>"], to "_Block": ["<all_urls>"],

I can open my page. I checked in console if there are any requests to other domains/ports - no. It makes single GET request to http://localhost:8090. What am I doing wrong?

Hello, Until recently, I was able to double tap the browser bar and have the window expand to fill the screen just short of "full screen" mode so I could still see the menu/task bar. I remember I did need to adjust settings for this somewhere but can no longer figure it out now that it is not functioning to this spec any more.

I did check about:config to see if "apz.allow_double_tap_zooming" was set to TRUE and it is, by following this suggestion below:

i have the same bug as described in this bug report: https://bugzilla.mozilla.org/show_bug.cgi?id=1946121

to put it shortly, after launching firefox, even when it goes to the "new tab", is always prompts for primary password. everytime. it also happens when i just go to a website like twitch. which im already logged into, it doesn't ask me to login on the website and firefox still prompts for primary password.

i am using windows 11, firefox version 138.0.4 (64-bit) my profile is synced with firefox. my windows machine does not have a password to log in. in the bug report they say it's solved with version 136.0.2 but obviously it still happens to me

i would really appreciate help fixing this because it's very frustrating.

I have been through other threads about enabling the Roboform toolbar icon. It has been a couple of years, multiple windows 11 PC installations, fresh installation. No roboform toolbar icon to this day. After multiple failures, I came up with a crazy fix I should never have to do. I am using the Firefox password manager in conjunction with Roboform. Just plain crazy. Any idea what might be going I would appreciate. I will cancel roboform if the problem cannot be rectified. Thank you Jeff

Hello. I've created about 15 saved tab groups and would like to create many more, but the lack of sorting by name (and, some might like, last used) is a hurdle.

I've not found a way to sort these groups. Has anyone been able to or is it just not possible?

Thank you and enjoy a super day! 🌞

When i'm on fullscreen in youtube or click any text or image in firefox a small white bar appears, i think is the same as the bar that appears when you are going to write something. It's pretty small but it bothers me, if anyone can help i appreciate.

Hello, as the title says. The help page is no help as features descibed do not exist. Take a look at the screenshot aswell.

What I did already:

Turned suggestions off. Removed the url from history and bookmarks + "forget about this site". DEL & SHIFT+DEL. Right click. There are no 3 dots to open a context menu. (contrary to what is stated on the help page)

I use an iMac and Macbook Pro. Autofill that used to work is no longer working on both of these when I go to USPS.com and sign up for updates on packages. It use to fill in my name on the top line and on the bottom line, it would fill in my email.

What can I do to get this feature back? It stopped working around the beginning of 2025.

Thank you, Martha.

I am currently running version 138.0.4 (64 bit). I have not been able to add any extension's tool to the toolbar. It used to be that a left-click on the "Extensions" tool produced a drop down window with a list of installed extensions and the option to and/remove any extension from the toolbar. Things still work this way with Microsoft Edge (Chromium) and Google Chrome. Left-clicking the new Firefox "unified extensions tool" opens an Add-ons Manager with "Recommendations", "Extensions", "Themes" and "Plugins". Clicking on "Extensions" does list the extensions I have installed, but there is no way to add the tools for those extensions to the toolbar.

Please, please, please put to original "Extensions" tool back on the toolbar. If you must add a tool to the toolbar for the "Add-ons Manager", do it. I actually think that would be a very good idea. Call the tool "Add-ons Manager", NOT "Extensions"!

NOTE: the computer I am running Firefox on in this instance does have my desired tools in the toolbar. I installed Firefox on this machine long before the newer versions of Firefox were released. I have used Firefox for years as my default browser on several computers over the years.

Thank you, William A. Butcher

How can I transfer all of my data and settings from Mozilla Firefox to the Firefox ESR version. I have Windows 7. I installed the ESR version but all of my bookmarks and settings disappeared. I still have the current version of Mozilla Firefox, which is no longer supported. If I can't easily and quickly incorporate all of my current settings, etc., to the temporary ESR version, and I uninstall the ESR version without that operation automatically uninstalling the current version?
