Greetings all, my trusty Firefox stopped working. Error Code PR_Connect_reset_error. Other browsers work fine. I have windows 10 with the latest updates and use Kaspersky Internet Security 21.3.10.391 (m). I have paused Kaspersky, uninstalled then reinstalled Firefox 3 times. I have cleared all Firefox cookies and caches a number of times. On my 2nd Firefox reinstallation Firefox worked ok for a couple of times then stopped again with the same error code. Please note that I am not very familiar with computer stuff so any suggestions need baby steps. Many thanks.

When I go to the website https://www.rebateinternational.com/RebateInternational/contactUs.do and I try to fill out the webform on that page and use autofill to fill in the e-mail address, it gives me an error message that says "please enter a valid email address" even though the e-mail address is valid. Also, if I do not use autofill, but simply type everything in manually, it still gives me that same error message. This problem does not occur in Google Chrome, but it does occur in Firefox. Sometimes I can solve the problem by erasing part of the email address and then re-typing that part, but that doesn't always work. It also doesn't work if I erase the entire e-mail address and type it in manually. The problem does not appear to be caused by add-ons and does not appear to be caused by hardware acceleration, because I have disabled add-ons and have turned off hardware acceleration. It also does not appear to be caused by cache and cookies, because the same problem occurs after I clear the cache and cookies. I will appreciate any response you can provide to help solve this problem.

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.

The icons on my home page suddenly became significantly reduced in size. Sure, I can tell what they are, and I've increased the text size for their identifiers below the icons. But they are now so small as to be not pleasing to the eye. How can I put them back the way they wuz?

The fucking forced dark mode has return despite the previous fix layout.css.prefers-color-scheme.content-override = 1 in about:config fixing it for years. This and the current replacement fixes don't save. I want a solution for PERMANENT light mode (black text on white background) for ALL menus, pop-ups, dropdown menus and hover over tab info.

And don't tell me to go search for a different theme I've already spent hours doing that and firefox has broken them only making some menus use the appropriate mode. On top of that I can't even pick an option to search for one that uses light mode I just have to go through each one and try it if I want to know which mode it uses that is NOT a solution to anything.

Replacement "fixes" for reference: ui.systemUsesDarkTheme won't even let me set to 0 only has true/false browser.theme.content-theme set to 1 browser.theme.toolbar-theme set to 1 (Why in the absolute hell these were added when a simple addition to preference setting wasn't is beyond me)

Very sorry for the aggressiveness but I am so very VERY tired of having to fight firefox on this preferance for years when their dark mode hurts my eyes.

When attempting to drag/Insert picture into email text, the message "The following files couldn't be attached: filename.jpg. Please try again later." appears. I have not been able to find a solution. The dragged/Inserted picture always ends up outside the email text box and cannot be moved into it. What is a solution?

Is this something new or do I need to reload Firefox? Firefox 133.03 64-bit is up to date on Windows 10.

It worked last Christmas!!! It is not important now that the holiday is over but would like to fix it.

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.

In the "General" section of my Firefox Settings, it states that "Your browser is being managed by your organization."

When I click on that, it shows the word "Certificates" under Policy Name, and "ImportEnterpriseRoots" under Policy Value.

Is this something that Firefox installed, or is it something a third-party (like my former company) installed on my computer.

Also, would this possibly slow down my computer?

Thanks for your feedback.

As a Chinese user, I am very dissatisfied with the inability to use the translation function. I request to add a Chinese option to the Firefox translation package. Thank you!

I use FF on desktop. Recently, I've run into a problem. My desktop browser will not load any pages... except Youtube. Youtube loads just fine, I can open a video or browse channels or community pages normally. I have fully reset my browser, reinstalled it, and disabled extensions. Other browsers on my PC will work normally. I have very few extensions: Sponsorblock for Youtube, uBlock Origin, and Facebook Container, that's it. I am not using a proxy or VPN. Troubleshoot mode did not fix the issue. I'm not the most tech savvy, so I apologize if I missed anything here.

Any insight is appreciated. Thanks!

I have Firefox on two Windows computers and was wondering what is the proper way to sync them.

One computer is not used often and I want to sync Firefox on it it with the Firefox on the computer I use daily so I want the Firefox that does not have the updated files updated using the Firefox data files on the computer I use daily and not the other way around. So what is the correct procedure to do this other than to make sure the Firefox program version is updated on the computer that is not used often?

Thanks

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

This is the second time I have put this forward. Using Firefox on Windows 10, I am unable to view yahoo emails. I get a white screen with a black bar across the top. Yahoo will tell me I have "5 unread messages". If I go into Yahoo using Edge, I can view the emails (which is why I think it must be a Firefox problem, but I may be mistaken. The one response was to empty the cache and such, which I have done and it doesn't help. Does Firefox not empty its cache each time I leave the site?

If this is a Firefox/Yahoo interactive problem, I apologize - it may be something about Yahoo. I have wandered all over their support sections though, without finding a potential solution.

Thanks for any support/suggestions you can make.
