Hello. I am setting up a site on Linux server using Apache as reverse proxy , with ASP.NET as application server . since installing SSL , I had few mixed content blocking that i was managed to fix using CSP directive in Apache configuration file. site has no issue with all browser except Firefox. the only issue is that in admin section , to configure a option. system will load a js file that simply a dropdown with list of options to choose from . when using Firefox , it tries to redirect that page to login page . for test , i clicked on the link i located in Developer tools , which directed me to login page , entered my credentials, and scripts loads showing the drop down box and ok button. is been 3 weeks i been looking for every solution and i have done everything .. but nothing have worked. now I am resort to having to use other browsers if i need to use that functionality in admin page. In page header file name : login , location : http://MYDOMAIN.ca/login?ReturnUrl=%2FAdmin%2FDiscountRulesCustomerRoles%2FConfigure%3FdiscountId%3D6%26_%3D1702682353293 , which are not correct . and browser such as Brave and Safari dose not show different path and file name and everything is correct. dose anyone know how to fix this .. ? i saw a solution mentioned as stated resting Firefox ,but can not find a way to reset , but i have reinstalled Firefox and constantly having this issue on this single section of the page . Thanks.

Opening PDFs automatically with Firefox and, without any changes I might make, saving them with the download function in Firefox, actually ruins the functionality and data entry function of that file. Specifically this happens with PDF files downloaded from the (not all that amusing) PDFs from the FINCEN, (US Financial Crimes Enforcement Network). I do not see why and how Firefox thinks it is allowed to change files that are simply downloaded and saved on Firefox.

In other words, it seems that Firefox strips away certain "permissions" and/or "functions" (like built-in lookup, menu or choice boxes). This means that the file so downloaded via Firefox can no longer be used to properly fill in data, or to look up and choose data items within the file. (I see many times that ANYTHING having to do with "permissions" tends to be an intractable and unsolvable problem for software makers & experts, so, if you do not know right away how to solve the problem, it will probably take you several years to figure this out.)

The PDF in question is created by a government agency. If you have ever dealt with a government agency, then you know that they act sort of like Adobe or Microsoft: "They don't respond, or they do respond & say they do not understand, and if they understand, they are either unwilling or unable to fix the problem."

If there is a switch or option within Firefox, which lets me tell Firefox "Save this file exactly like it is received, nothing added or removed!", that would be nice. I just have not found such an option yet, and it would be nice if it might get provided someday.

I will share my browser data, but I am sort of convinced that a detailed question like mine will not be addressed within that shared data.

Hi!

I am getting messages that I am blocking ads for many of my internet requests. I had never received these before but all of a sudden I started to get them. I have tried a number of things but nothing works.

I am running Windows 11 and do not have any Ad blockers.

I use Firefox on a Dell Windows 11 laptop. This morning, when I opened my Outlook email, I discovered that in-message links no longer opened in Firefox (my default browser). I've checked everything I and other people can think of on the Outlook end--I'm waiting for further suggestions there--but I'm wondering if some Firefox setting could be causing the problem. Does anyone have any suggestions on where I could start looking?

Printing will not show up when I select print, only save shows. What can I do? When I use a different browser it works fine. Only when I use Mozilla, I can't print.

this is a request. i have maybe 100 tabs open at any one time to support my research projects. i've recently used the group tab function--thank you Mozilla--but now i find a need to go to a group directly. firefox view does not currently support a "sort by group" function. it has sort by recent activity and sort by order, and a general search function. but it would be great if it could also sort by group in firefox view, too. can do? thank you, C Baron

I can't see payment methods or credit card info in settings, there's no option Autofill and there is no Saved payment methods button I have added CY (my country CYPRUS) in about:config extensions.formautofill.creditCards.supportedCountries still not working

I have Windows 11 version 25H2, and Firefox 145.0.2 I'm having problems connecting to some sites, e.g. Amazon.fr The problem is the same on other sites, i.e. it takes a long, long time to connect to a site or within a site. I have tried various solutions such as: running Avast Clean Up, restarting my computer, clearing the history in Firefox before trying to connect but nothing seems to help. What's gone wrong and what's the solution?

Hello, All bookmarks disappeared after last update on Sunday 11.2.25. Is there a way to search some files and recover them? This is currently a big problem for me as all bookmark are related to our business.

Dear Firefox Team,

It has re-occurred to my Firefox Browser of the latest version of 115.30 with some websites which I have recently visited however which have appeared 8 grids of blank or white pages again under "Recent Activity" as attached with the image for your technical troubleshooting suggestion.

Those 8 grids of Recent Activity in the older version of Firefox browsers used to have shown colorful graphics or images representative of the recent websites I visited in the recent past.

May I know what I am supposed to do to recover those graphics or images?

Kindly offer any suggestion or solution?

Thank you for your kind attention.

I have a rather odd question. I have a website with a background video that autoplays made with Squarespace. The video plays fine in every browser, except maybe 10-20% of the time will only pull up the spinning white wheel with black background but just in Firefox. I have been through all troubleshooting, DRM settings reset, Cache cleared, hardware acceleration turned off, browser up to date - but none of it gives me a permanent solution. The video itself is up to correct spec in Squarespace, does anyone know what I'm missing? Thank you in advance.

When I right-click on a website and choose "send page to device", I get the notification "Sent!", but nothing actually happens on my other device. Yes, I am logged in with the same sync account on both devices.

OK when I restart firefox, or have been using it for a while, I might decide that I'd like to close a TAB or maybe even a heap of them.

Trouble is that someone has decided that when people close a TAB, the one to the right, automatically reloads.

I don't want to reload a TAB I am not currently using, I just want to close the TAB or TABS, that I am no longer using.

Stop doing this really retarded "Oh we think this is a good idea to automate things - you don't want, don't need and have not asked for, with the typical NO choose to switch it on, and NO off switch".

Seriously provide the option to turn this function on, and to turn it off.

AND up till the day this never happens, is there a switch in the about:config to turn this highly undesirable and useless function off?
