I received a Mozilla Firefox (64) update notice going for version 132. When it didn't complete, I checked that my version is Firefox ESR115 (115.17.0), which operates with Windows 7-8.1. I have Windows 10, which matches with your version 132. So my question is how do I change/update my Firefox over to match up with Windows 10 and the Version 132 update?

I have every about:config and settings option set to recommended to prevent autoplay videos. NONE work with yahoo. The vids will drop to the lower right hand corner but even if I click on the close window X they still pop open again. And again. And again. Is there a solution to this arrogant, self-centered behaviour by yahoo?

I am planning to buy a new computer to replace my current one. The new computer will have Windows 11 and the current one Windows 10. I notice the current Thunderbird files are located in C:\Users\(username)\AppData\Roaming\Thunderbird. I backup these files every day. When I install Thunderbird on the new computer, do I copy my backed up files to C:\Users\(username)\AppData\Roaming\Thunderbird BEFORE starting the Thunderbird application on my new computer for the first time? Will Thunderbird be able to locate all of my email accounts as well the current local files? Is there anything that I need to do and/or change? Thanks for your help.

My extensions are not showing up in the firefox browser, on menu bar, tool bar, or bookmarks bar. I am elderly and NOT computer literate. What to do? Using Windows 10.

Thank you.

Within the last week, my homepage has changed in look and operation. It no longer has all of my bookmarks, I can no longer navigate back to my homepage from other sites, etc. Also, it have a very plain, sterile display. What changed and how to I get back to my original homepage?

I understand that as from 14th March 2025 I will need to update Firefox. I am currently running 102.0 and have sucessfully prevented Firefox from updating to later versions. I did this to prevent the updates positioning the tabs in the wrong place. Please can you tell me if the CSS script that I use to put them back into their correct position, i.e. below the Bookmarks Toolbar, will still work.

Also, will newer versions allow the user to choose where the tabs are positioned? It was possible to do this in earlier versions and the choice is also available in other browsers.

I have also managed to stop Windows 10 updating for several years too, Microsoft kept altering my laptop in unacceptable ways.

I have Thunderbird 115.15.0 on win 10 dell xps desktop and want to install Thunderbird on my new win 11 Dell xps. The microsoft store gave me ver 128.5.2. I read that if I use the same version I can transfer my profile from the old computer. How should I approach this? Should I figure out how to update the win 10 machine to 128.5.2 before transferring the profile?

I have Firefox version 136.0.2. I think it was quite recently updated. The right click menu is broken. The choice list is much longer, and the choices "open link in new tab" and "copy link" (ones I tried) do not work. This only started happening this morning. Right click works fine in Chrome. Screenshot included.

Hi,

I am developing a website of my own and in that website I want to implement a handler for Content-Security-Policy violation reports. I want to test if this handler works as I expect and therefore I have configured a webpage such that is will report CSP violations (I see them in the web developer console) and I want to have them sent to my application's CSP-violation handler.

In my test environment, the application is running on localhost. I have run my web application both on HTTP and HTTPS (with a self-signed certificate), but in neither case Firefox is sending any reports to my application.

My CSP headers look as follows: Content-Security-Policy: report-uri http://localhost:5281/csp-violation;base-uri 'none';default-src 'self';form-action 'none';frame-ancestors 'none';report-to csp-viol;script-src 'unsafe-eval' 'nonce-9FuQ3NuVoW66DT1ZU4w9EPSymnHE1/hg';style-src 'unsafe-eval' 'nonce-9FuQ3NuVoW66DT1ZU4w9EPSymnHE1/hg' Reporting-Endpoints: csp-viol=http://localhost:5281/csp-violation Report-To: {"group":"csp-viol","max_age":10886400,"endpoints":[{"url":"http://localhost:5281/csp-violation"}]}

When I run my application using HTTPS, all HTTP in the endpoints will also be HTTPS.

I have verified that when I post something by hand to http://localhost:5281/csp-violation, my handler is executed, so that is not the issue. I believe that Firefox is just not sending the reports. Is there a way to configure Firefox such that it will send the CSP violation reports to my application when run on HTTP(S) on localhost?

Sincerely, Marcel

I always use the middle mouse button (pressing the scroll wheel) to open and close new tabs, but since the update, it doesn't work anymore and now types "=" if the cursor is in a text field. For context, I use an MX Master S3, mapped with Logi Options+.

Anyone else having this issue? How do I roll back to the previous version??

SOLVED: It was a bug with Logi Options+, not Firefox. When I hovered over the tab for the presets I had for CaptureOne, I noticed it also said Firefox. So seems something weird happened there. Deleted that preset and the issue in Firefox went away.

I couldn't find a way to delete this thread, though.

When I logged into my laptop on 9th November Firefox had closed. This happens sometimes, I'm often not sure why, but this time the previous session didn't automatically repopulate when I restarted. I navigated to the history options with the idea of retoring the previous session - either using that functionality or individually opening previous windows - but history was blank and the previous windows option was greyed out. Following suggestions online I've looked for .bak or .json or similar files to use as restore points but there's nothing since much earlier in the year up to 8th November, which are pretty much empty, and the 9th.

I'd be very grateful for any suggestions!

Dear Mozilla Firefox Team,

I hope this message finds you well.

We manage a network of workstations that frequently utilize the Mozilla Firefox browser. Recently, we have encountered a situation where many of our systems are showing vulnerabilities due to pending browser updates. The updates are being installed successfully; however, users often neglect to restart the browser, which is crucial for completing the update process and ensuring security.

To address this, we would like to inquire if there is an existing Group Policy that can be configured to automatically notify users when they need to restart their Firefox browser to apply the latest updates. Such a feature would greatly assist us in maintaining the security integrity of our workstations and ensuring that users are made aware of the importance of restarting their browsers when prompted.

If this functionality is not currently available, we would appreciate any insights on potential workarounds or future plans to incorporate such a feature.

Thank you for your attention to this matter. We look forward to your response.

Firefox is used on Windows 11 Enterprise. There is a firefox.cfg in the installation directory (and an autoconfig.js in the ./defaults/pref sub-directory). Everything works fine when a pref(...); entry is written to the firefox.cfg. However, we want the firefox.cfg to call the pref(...); entries from a global_config.js which is saved on the machines public directory.

Therefore, the firefox.cfg says:

// free line lockPref("autoadmin.global_config_url","file:///C:/Users/Public/.../global_config.js");

But firefox does not load whatever prefs are written to the global_config.js. There probably is problems with the formatting of the file path (file:///C:/Users/Public/.../global_config.js). What would the correct formatting look like? Unfortunately, Mozilla´s support guide only includes an example code for a firefox.cfg which calls a global_config.js via http:, but not via file:.

I pay my utility bills online and the utility company websites won't load in firefox but do in edge. Also various other sites wont load with an error message captcha incorrect, but no captcha shows on the screen. It's getting frustrating waiting for websites to load and getting no results. Thank you, Ann DIngee
