Hello. I should use proxy to visit some websites. I do not want open Preferences each time. Also I need list to exclude website which should be without proxy anyway.

How to do this?

I use tabs within windows to keep track of to-do items/wish lists etc. I had about 5 windows open with anywhere from 10-30 tabs each, my firefox closed unexpectedly and did not give me the option to recover the windows and tabs as it has before. Any way I can recover these or am I screwed? Thanks.

Firefox version: 102.0 (64-bit) System: Windows 10 21H2

I recently downloaded a file that may have had some sort of virus or malware. The file came up negative in Windows Defender and Malwarebytes but I deleted it anyways; however, I still get a download popup every time I open Firefox telling me that "This file contains a virus or malware." I've cleared the download library and browser history (cookies, cache, etc.) but I still get the popup from the Firefox.

Is there any known fix for this? Thanks!

When I paste the following URL into the URL bar, it works on Chrome and Edge, but Firefox returns a 404 (page not found):

How can I get Firefox to recognize encoded URLs?

The un-encoded URL works, but is fragile because of the hyphen-minus characters. The source text is on a Powerpoint slide, and preservation of the hyphen-minus depends on the PDF writer, any PDF tools used (croppers, n-uppers, rotaters, page manipulators/extractors/combiners, etc.), and the various systems on which the document is processed.

I've gone through all of the steps to reset my Firefox browser and attempted to change my search engine from Duckduckgo to Startpage. Every time it works a couple of times then Duckduckgo hijacks the search engine back to itself. I've deleted this search engine, reset my browser, said yes to prompts by Startpage to be the default browser, and tried everything that I can think of. Very, very frustrating. And I start to worry about the security of the Firefox browser itself. Any ideas?

Thanks, David

Hello,

I lost my bookmarks when I changed my password. Can Firefox recover them on its servers? I've seen many similar complaints arising from similar problems. One would think that Firefox would address this issue to improve the user experience.

Firefox has assigned my .cpp files as type "Git", but .cpp files should be type "Visual Studio 2019". How do I change the type "Git" to "Visual Studio 2019" for .cpp files, so when I want to save or open a .cpp file the Firefox Applications matrix assigns .cpp files to Visual Studio 2019?

My desktop icon gave me a bad link error message, what happened to my forefox account? I upgraded, checked the save settings, and EVERYTHING is gone. All of my saved logins for several hundred sites. How can I restore them?

Please help me! Last week, was the victim of a computer scam. I called the 888# pop-up on screen. Looked so real w/MS logo and MS defender logo. I stupidly gave my IP address, name, cellphone #, (which I reported to MS fraud division and the FBI). (I installed a VPN, after the fact.) I can't believe I was so taken in by this guy.

  I went to my bank in person and gave them my new email address.  I tried to log in to my online banking today. Message "Secure Connection Failed. You are not securely connection to this site.Your connection to this site is not private. Information you submit could be viewed by others (like passwords, messages, credit cards, etc.) "
Now, I'm terrified that this scammer has access to my computer.
I'm afraid to access my online banking. He may even have access to my other online accounts, such as my cable, retail stores, etc. where I changed my email addresses and passwords.
Even if I can get "securely connected" how do I know I'm safe from these guys who have my IP address?
 What can I do?  Can someone please help me? Or make a suggestion as to where I can go to resolve this (if possible?
 Thank you so much.

i get 'server not found' and 'try again' window when trying to access sites and even within sites if i manage to get on - after several 'try again' clicks

could this be related to recently installed fibre optics or do i have a virus - my anti-virus protection is bitdefenders
